Thanks for the toolkit - most useful!

I needed to be able to search for people using name and company, and then
get the person's public URL.  I think to do that I need to get a search
result and then ask for the Person with ProfileField.PUBLIC_PROFILE_URL. 
Some of those results will be outside of my network, and to get
out-of-network profile data by ID it appears that the headers from a
previous search need to be provided.  

If there is a better way to get that information let me know, but what I
did was add a new getProfileById method to LinkedInApiClient.java and
BaseLinkedInApiClient.java.

LinkedInApiClient.java:

    /**
     * Gets the profile by id, request and fields.
     * For details see <a
href="http://developer.linkedin.com/docs/DOC-1002">http://developer.linkedin.com
/docs/DOC-1002</a>
     * 
     * @param id the profile id 
     * @param headers the request headers
     * @param profileFields the profile fields
     * 
     * @return the profile by id
     */
    public Person getProfileById(String id, Headers headers,
Set<ProfileField> profileFields);

BaseLinkedInApiClient.java:


    /**
     * {@inheritDoc}
     */
    @Override
    public Person getProfileById(String id, Headers headers,
Set<ProfileField> profileFields) {
        assertNotNull("id", id);
        assertNotNull("profile fields", profileFields);

        if (headers != null) {
            LinkedInApiUrlBuilder builder =
createLinkedInApiUrlBuilder(LinkedInApiUrls.GET_PROFILE_BY_ID);
            String                apiUrl  = builder.withField("id",
id).withFieldEnum("profileType",

ProfileType.STANDARD).withFieldEnumSet("profileFields",
                                                    profileFields).buildUrl();

            return readResponse(Person.class, callApiMethod(apiUrl,
headers.getHttpHeaderList()));
        } else {
            return getProfileById(id, profileFields);
        }
    }

I have *not* run this through any unit tests (ran into throttle limits
during the development...).

Thanks again,
Doug.

Currently when throttle limit for a resource is reached, the library throws
403 Forbidden exception. It should show appropriate message.

Hi Linkedin-j author:
      I want to build a linkedin-based app for my customer, but the jar do
not work on 1.5JDK because of the Marshall Class.
      How to deal with it. Need your help.



       Thanks.

What steps will reproduce the problem?
1. Run a client.updateCurrentStatus from within the Google AppEngine java dev 
environment.

What is the expected output? What do you see instead?
The expected output is the setting of the status.
Instead you get a container exception complaining about redirecting a client 
request.

What version of the product are you using? On what operating system?
1.0.335-rc2 on MAC OSX 10.6
Google Appengine dev server for Java 1.3.7

Please provide any additional information below.

Adding the following to line 1904 of BaseLinkedInApiClient.java fixes the 
problem.
1904:             request.setInstanceFollowRedirects(false);
Just before:
1905:             request.connect();

The problem is that the local HttpClient library used by appEngine (including 
1.3.7) automatically sets FollowRedirects to true, which is invalid for a PUT 
operation. 

I've only tested this with updateCurrentStatus.  Not sure about the rest of the 
API calls.

Add support for specifying a callback url while requesting a request token
from oauth service.

Hi Nabeel,

As your code implemeted for company data, there are 3 fields that can be
retrieved:type, name and industry. I found out on LinkedIn more company
data, such as: address, website, number of employee, etc. I want to
retrieve these data also, so could you please show me where in your code I
can adjust to do this. 

Thank you very much,
Quyen

What steps will reproduce the problem?
1. Downloaded the jar from the path, 
http://code.google.com/p/linkedin-j/downloads/list - (May 24) - 
linkedin-j-0.1-rc4.zip 
2. Inlcuded the jar in the class path and try to access the class in the jar.
3.

What is the expected output? What do you see instead?
The expected output is that the method has to run and gives the required 
objects.

 Exception in thread "main" java.lang.NoClassDefFoundError: oauth/signpost/signature/OAuthMessageSigner

What version of the product are you using? On what operating system?
The version downloaded is May24 the build. Working on Windows 2000 professional 
operating system.
Working wiuth Eclipse Ganymede. The jdk used is 1.6 version.



Please provide any additional information below.


I need the following to be printed.
            System.out.println("Request token: " + requestToken.getToken()); 
                System.out.println("Token secret: " + requestToken.getTokenSecret()); 
                System.out.println("Expiration time: " + requestToken.getExpirationTime()); 


Code:

// In consumerSecretValue & consumerKeyValue specified the key got from 
developer\apps.

            final String consumerKeyValue = "consumerKeyValue "; 
                final String consumerSecretValue = "consumerSecretValue "; 

                final LinkedInOAuthService oauthService =       LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(consumerKeyValue, consumerSecretValue); 

                LinkedInRequestToken requestToken = oauthService.getOAuthRequestToken();                  

                String authUrl = requestToken.getAuthorizationUrl(); 

                System.out.println("Request token: " + requestToken.getToken()); 
                System.out.println("Token secret: " + requestToken.getTokenSecret()); 
                System.out.println("Expiration time: " + requestToken.getExpirationTime());

Kindly help us to get rid of this issue. 

Hi,

Can you deploy your linkedin api jar's in any maven repo so that we can use 
easily?.


You can also use your google code svn as maven repo. See the below link for 
more info.

What steps will reproduce the problem?

Trying to generate the OAuth request token throws an exception on the Apache 
Tomcat Server.
The following code works fine on the desktop in a NetBeans 6.7 project and it 
also worked previously on Apache Tomcat web application using servlets built by 
Netbeans 6.7. However, its stopped working on the server now

/***********************************************************************/
Code which throws the exception
/***********************************************************************/

private static String generateLinkedInUrl(){
    try{
    final LinkedInOAuthService oauthService = LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(LINKEDIN_CONSUMER_KEY,LINKEDIN_CONSUMER_SECRET);
    String callbackUrl="http://addison.cyberonix.net/CatServer/LinkedInServlet";
    LinkedInRequestToken requestToken = oauthService.getOAuthRequestToken(callbackUrl);
    String url=requestToken.getAuthorizationUrl();
    //session.setAttribute("LINKEDIN_REQUEST_TOKEN", requestToken);
    System.out.println(url);
    return url;
    }
    catch(Exception ex){
        ex.printStackTrace(System.out);
    }
    return null;
    }

}

/***********************************************************************/
What is the expected output? What do you see instead?

Windows works ok
Apache Tomcat on Linux throws the exception

Please provide any additional information below.

What steps will reproduce the problem?
1. Fetch the list of network updates using the library.

There is no method in the library to retrieve the comments associated with
a network update.

Hi,

Can you provide support for fetching messages,invitations?.

What steps will reproduce the problem?
1. Fetch access tokens of a user for the first time using signpost library. And 
Storing them
2. Using these tokens later and post a share using LinkedInApiClient class
3. post share with LinkedInApiClient's object . postShare() method.

What is the expected output? What do you see instead?
Expected Output: The share is updated in user's linkedin profile.
Current output: com.google.code.linkedinapi.client.LinkedInApiClientException: 
java.io.IOException: Received authentication challenge is null
it's in android Logcat and in web browser I can't see status updated

What version of the product are you using? On what operating system?
Android 1.1, with Signpost library for o auth. 

Please provide any additional information below.
It works well if user need to authorize my application every time but when i 
skip this step and use stored tokens instead I was thrown an error

Tried with the OAuthAuthenticationExample.java

specified the consumer key and secret option, but the error appears:

due to the OptionValidator class

there are a couple of '-' in the key and secret option

How do i counter this problem??

Any help is welcome.

Hi Nabeel,

I did some research on the exception but still couldnt find the solution.
Do you have any solution or hint on the problem?

Thank you in advance,
Quyen

The implementation for ProfileField.RELATION_TO_VIEWER_RELATED_CONNECTIONS is 
missing so I had to add one myself. Attached are the changes I did to make it 
working.

What steps will reproduce the problem?
1. Retrieve a profile education records
2. Examine the education record

What is the expected output? What do you see instead?
Expect to see Major in addition to degree. It appears in the linkedIn API 
documentation

What steps will reproduce the problem?
1.Downloaded latest versions of signpost and linkedin api
2.Using netbeans IDE 6.8
3.

What is the expected output?
I expect to get the user's profile

What do you see instead?
The line producing an error is 'Person profile = 
client.getProfileForCurrentUser(EnumSet.of(ProfileField.ID));'

the exception below is produced

'com.google.code.linkedinapi.client.LinkedInApiClientException: 
java.lang.IllegalArgumentException: attribute name can not be null'

What version of the product are you using? On what operating system?
Linkedin-j latest version
signpost 1.2.1.1 is also in my classpath
windows xp

What steps will reproduce the problem?
1. while retriving OAuth request token 

What is the expected output? 
Expected output should get the token key and token key secert

What do you see instead?

Hi Nabeel,

I am testing OAuthAuthenticationExample, the program only executes
printHelp(options). I don't change anything in the code. I don't know how
to specify the consumer key and secret on command line as program
arguments. Could you please show me how to do that?

Also, I already included the jar file from dev-lib, dist, jaxb-lib, lib
folders to my classpath. Do i still miss any jar files?

Thanks in advance,
Quyen

LinkedIn API site supports GZip compression. So it would be good to have
that support built into the library and enabled by default. This will
result in efficient utilization of network bandwidth.

What steps will reproduce the problem?
1. add lines below to OAuthAuthenticationExample main method
    Properties systemSettings = System.getProperties();
    systemSettings.put("https.proxyHost", "myprox");
    systemSettings.put("https.proxyPort", "port");
    systemSettings.put("https.proxyUserName", "name");
    systemSettings.put("https.proxyPassword", "mypassword");
    System.setProperties(systemSettings);
2. run OAuthAuthenticationExample 
-consumerKey xxx --consumerSecret xxx

What is the expected output? What do you see instead?
Now visit:
https://www.linkedin.com/uas/oauth/authorize?oauth_token=xxxxx
... and grant this app authorization
Enter the PIN code and hit ENTER when you're done:

What version of the product are you using? On what operating system?
Simulator

Please provide any additional information below.

Hi Nabeel.
Thanks for your library. I have tried it and i keep getting this error.

 'com.google.code.linkedinapi.client.LinkedInApiClientException: java.lang.IllegalArgumentException: attribute name can not be null'

The exception is being thrown by this line:

Person profile = client.getProfileForCurrentUser(EnumSet.of(ProfileField.ID));

 can you please help me out.I am using the latest linkedin-j and signpost 1.2.1.1. the problem persists even when i use the no_argument constructor 'getProfileForCurrentUser()'.

Regards, Eugene

What steps will reproduce the problem?
1. Call LinkedInOAuthService.getOAuthRequestToken() with a callback url.
2. Open the authorization url in a browser.
3. Authorize the application.


What is the expected output? What do you see instead?
The application should be redirected to the callback url. Instead a 404
error message is displayed.

What steps will reproduce the problem?
1. Call the Invitation API through the library

Instead of the response we get:
Caused by: java.io.IOException: Server returned HTTP response code: 400 for

This is a known issue and is also posted at
http://developer.linkedin.com/docs/DOC-1035.

What steps will reproduce the problem?
1. Using the library try to fetch profile of the user specifying field
selectors that contain '/' like ProfileField.LOCATION_COUNTRY_CODE.
The library throws an exception.

com.google.code.linkedinapi.client.LinkedInApiClientException:

A question about the correct syntax of specifying the field selectors with
'/' has been posted on LinkedIn API forums.

Some network update types (e.g. recommendations given) are not available
through the API.

Both the domain model and the api needs to be updated to accomodate all
available network update types.

Removing the dependency of external jars will make the library more
reusable. Will need to implement OAuth on our own.

What steps will reproduce the problem?
1. In the web application first get all my connections.
2. I list all the connections on the UI with selection.
3. I try to send message to selected connection using the api.I get a http 401 
response.

What is the expected output? What do you see instead?
Should send a message.But i get a 401 error.

What version of the product are you using? On what operating system?
Latest available on window XP Professional.

Please provide any additional information below.
Getting connections & sending message when performed separately it works fine.

What steps will reproduce the problem?
1. Get the network updates through the API.

In the returned object the id of the person is invalid.

This is a known issue in the API and is also posted here:
http://developer.linkedin.com/docs/DOC-1035

What steps will reproduce the problem?
1. Create a client
2. access a method that communicates with linkedin
3. access a method that communicates with linkedin

What is the expected output? What do you see instead?
Should have no problems, instead the first method works fine, then the
second method throws exceptions LinkedInApiClientException: Stream Closed

What version of the product are you using? On what operating system?
most 0.1rc3 android

Please provide any additional information below.

Hi Nabeel,

I tried to set up the proxy, but it still doesnt work, something like this:
        Properties systemSettings = System.getProperties();
        systemSettings.put("http.proxyHost", "proxy");
        systemSettings.put("http.proxyPort", "8080");
        System.setProperties(systemSettings);


Do you have any hint???

Thanks in advance,

Hi,
    Now we use the linkedin api to build application for end users.
    but the api is limited in data transfer\ features.

    Will the api provide the job\inmail feature? Will the linkedin websites
build their own client like facebook? or totoally open as twitter?
   \
     What's your linkedin api strategy?

What steps will reproduce the problem?
1. Using sample OAuth code, call:
requestToken = oauthService.getOAuthRequestToken(callbackUrl);
without or with null callbackUrl.
2. System attempts to make authorisation.
3. LinkedIn responds with 401: Invalid Signature 

What is the expected output? What do you see instead?
It may be better to throw an exception before sending off to LinkedIn 
indicating no callbackUrl provided. This was causing us hell trying to work out 
where it went wrong, simply because LinkedIn's response was so convincing! The 
actual error was in our code miles away to do with config... 

What version of the product are you using? On what operating system?
Latest (6 Sept 2010), Mac OS X Snow Leopard 10.6.6

NB: This maybe better in the 'gotchas' pile

Hi Nabeel,

Is this possible to hard code user name and password of linkedIn account so
that the user doesn't have to go to the authorization page to grant the app
authorization???

The library can be ported to Android with minor changes (since jaxb is not
currently available on android.). Also need to make an example application
for android that uses the features of the library.

The current build file was autogenerated by eclipse and is not 100%
perfect. It needs to be corrected. Plus I have to enable maven dependency
management for the project.

What steps will reproduce the problem?
1. Try to get the connections of a user by his own email.

Instead of returning the connections, it throws the following exception:
Caused by: java.io.IOException: Server returned HTTP response code: 403 for

This issue has also been posted on the LinkedIn API forum:
http://developer.linkedin.com/thread/1265

Hi Nabeel,

thanks for the work you've done. Could you please have a look at this issue ?

What steps will reproduce the problem?
1. Authenticate
2. Get a User object with 
getProfileForCurrentUser(EnumSet.of(ProfileField.MEMBER_URL_RESOURCES));
3. Call profile.getMemberUrlResources();

What is the expected result? What do you see instead?
Expected a MemberUrlResources instance that gives access to multiple resources
Received a MemberUrlResources instance with a single .getMemberUrl() method

As long as it is possible to enter multiple websites on a profile I expected to 
get multiple 
resources.

Thanks

Nicolas

The library currently fetches most recent 5 comments for each network
update. The LinkedIn API also includes call to fetch all comments. Need to
incorporate that in the library. Also the id and timestamp of an update
comment are not available through the library but they are available
through the API. This needs to be fixed as well.

What steps will reproduce the problem?
1. use the postShare method
2. Post the following status "Rêvez vos voyages, et voyagePlus s'en occupe"

The status displayed on Linkedin looks like:
R�vez vos voyages, et voyagePlus s?en occupe

Any solution on how to encode those special characters?

What steps will reproduce the problem?
N/A

What is the expected output? What do you see instead?
It would be nice if the API supported the actions "like" and "comment" on 
network updates

What version of the product are you using? On what operating system?
N/A

Please provide any additional information below.

Any thoughts on having LinkedInOAuthToken implements java.io.Serializable?
 That way you could stick a LinkedInRequestToken in an HTTP session, for
example, so that it can be reused on a subsequent request when you need to
get the access token with it.

Hi Nabeel

I got this exception when hitting the following line in
OAuthAuthenticationExample: 
LinkedInRequestToken requestToken = oauthService.getOAuthRequestToken();

In order to reduce the number of LinkedIn API calls I need to the following to 
the ProfileField enum:

RELATION_TO_VIEWER_RELATED_CONNECTIONS_FIRST_NAME("first-name", 
RELATION_TO_VIEWER_RELATED_CONNECTIONS, false),

RELATION_TO_VIEWER_RELATED_CONNECTIONS_LAST_NAME("last-name", 
RELATION_TO_VIEWER_RELATED_CONNECTIONS, false),

RELATION_TO_VIEWER_RELATED_CONNECTIONS_PUBLIC_PROFILE_URL("public-profile-url", 
RELATION_TO_VIEWER_RELATED_CONNECTIONS, false),


Is there a flexible way to specify such fields without hacking the library?

I basically want to do something like this:

Person person = client.getProfileById(id, EnumSet.of(
                ProfileField.FIRST_NAME, ProfileField.LAST_NAME, ProfileField.HEADLINE,
                ProfileField.PUBLIC_PROFILE_URL, ProfileField.RELATION_TO_VIEWER_DISTANCE, 
                ProfileField.RELATION_TO_VIEWER_RELATED_CONNECTIONS, 
                ProfileField.RELATION_TO_VIEWER_RELATED_CONNECTIONS_FIRST_NAME, 
                ProfileField.RELATION_TO_VIEWER_RELATED_CONNECTIONS_LAST_NAME,
                ProfileField.RELATION_TO_VIEWER_RELATED_CONNECTIONS_PUBLIC_PROFILE_URL));

In ProfileField, there is no constant for the field "interests" but there is on 
the Person class.  There should be a constant in ProfileField named INTERESTS 
that maps to the LinkedIn field "interests" and calls 
Person.setInterests(String) when a Person is inflated.

What steps will reproduce the problem?
1. Try to access a profile on the connections of a user by url.

Instead of returning the profile or connections it throws the exception:
Caused by: java.io.IOException: Server returned HTTP response code: 400 for
URL:

This has also been posted on the LinkedIn API forum:
http://developer.linkedin.com/thread/1264

Please implement new search API(http://developer.linkedin.com/docs/DOC-1191) 
replacing the existing search API(http://developer.linkedin.com/docs/DOC-1005) 
because the present search API is deprecated according to the linkedin 
developer Network.

Hi Nabeel!

Do you plan to add support for other profile fields, such as `date-of-birth`,  
`im-accounts`, `phone-numbers` or `twitter-account` and others, described in 
http://developer.linkedin.com/docs/DOC-1061 ?

What steps will reproduce the problem?
1. Downloaded the latest source files.
2. Compiled the sources using eclipse.
3. Ran the OAuthAuthenticationExample as a java application specifying my 
consumer key and secret.

What is the expected output? What do you see instead?
Example should work as expected.But i get the following exception.

What version of the product are you using? On what operating system?
I downloaded the following zip "linkedin-j-0.1-rc4.zip" and using it on windows 
XP.

Any help would be much appreciated.

Thanking you,

Vinay 

What steps will reproduce the problem?
1. I'm unable to use the last published snapshot in my project, so I downloaded 
the source.
2. Though I'm unable to build the tool on the command line using ant or maven.
3. Importing the project into eclipse and running the sample authentication 
code in eclipse works  
though.

it would be great if you can publish a snapshot that works or update the build 
scripts so people can 
build and use trunk. 
Beside that - awesome project, thanks!
