Hii, I want to know how the server could be changed to tomcat 8? Please tell me the plugin type for this issue.

Hi

After adding following Spring security setups

• dependency injunction in pom.xml
• SecurityConfiguration.java
• Added filters in web.xml
• Other configurations in todo-servlet

I am getting the following error, please help. I have deleted and reinstalled the whole project and get same error page.

javax.servlet.ServletException: Servlet.init() for servlet dispatcher threw exception

This:

log4j
log4j
1.2.17

Should be changed to this: 1.2.16
Otherwise there will be error:

I have problem with step 3, Passing request parameters using get method. The attribute is not defined in JSP and blank. If I change the line to:

request.getSession().setAttribute("name", name);

then it works. I also have problems with that I have to press reload before the changed parameter shows up in the JSP page output - simply change in address bar and press return does not update the page. I'm using Edge browser.

It seems to me that I do all I should do:

1. I changed file pom.xml
2. I created file webapp/LoginServlet.java
3. I created file webapp/WEB-INF/web.xml

On localhost:8080 I see:
HTTP Status 404 - /
type Status report

message /

description The requested resource is not available.

Apache Tomcat/7.0.47

What mistake I made? What should I check?

Getting issue : java.lang.IllegalStateException: No Java compiler available

Jars/Maven Dependencies: After going through couple of blogs added jars including ecj and jsp-api.jar. But the issue persists. Can I get some help here.

log4j:ERROR Could not find value for key log4j.appender.Appender2

after login page its not moving to login-do

My pom.xml is the same, but for some reason I had to add an asterisk to
<context:component-scan base-package="com.in28minutes.*" />
in todo-servlet.xml (Step 12)

I have Luna Service Release 2 (4.4.2)

Hello Sir,
How may I change the complete server. Through Maven to normal Apache server. I did try but the request is not getting handled.
Thanks, Warm Regards.

I'm new on SpringMVN and I just stated the course. I got a few issues, the import javax.servlet.annotation.WebServlet, javax.servlet.http.HttpServlet,javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse cannot e resolved. Any clue? Thanks.

This error happens because of:

https://github.com/in28minutes/SpringMvcStepByStep/blob/master/Step11.md

/pom.xml

4.2.2.RELEASE
just change it to

4.2.3.RELEASE
and it will work, no matter if you use Java 7 or Java 8

If you download project from GitHub, you can see that in Step11.zip there is version 4.2.3 while in Step07.zip there is version: 4.2.2

It would be great if this would be corrected in: https://github.com/in28minutes/SpringMvcStepByStep/blob/master/Step11.md

It took me some time to find cause of this error, might save time for some one else.

Hello sir,
I am having trouble at step 27 while validating an add-a-new-todo request. When i enter more than 6 characters, the code executes normally. Although when i enter less than 6 chars, it returns;

java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'todo' available as request attribute.

Rest of the code flows normally. Here is the code of add controller.

@RequestMapping(value = "/add-todos", method = RequestMethod.GET)
public String showAddTodoPage(ModelMap model) {
model.addAttribute("todo", new ToDoBean());
return "add-todo";
}
@RequestMapping(value = "/add-todos", method = RequestMethod.POST)
public String addTodo(ModelMap model, @Valid ToDoBean todoBean,
BindingResult result) {

	if (result.hasErrors()) {
		return "add-todo";
	}
	String user = (String) model.get("name");
	todoService.addTodo(user, todoBean.getDesc(), new Date(), false);
	model.clear();// to prevent request parameter "name" to be passed
	return "redirect:/list-todos";
}

I have uploaded the code here. Thank you sir.

in28Minutes-first-webapp.zip

When we edit the description using edit option, it is not reflected when you see the todo page (Step 29)

When editing Todo (Step 28), seems like it is adding a new Todo with new desc and not deleting the old todo that is in code in TodoService.java (updateTodo function)

I don't understand how does the updateTodo function in TodoService.java removes the existing todo and add a new todo as it doesn't work when I try doing that.
