Unable to cast ApexClass into sobject_x when calling the create method. about apex-toolingapi

[tquilapratyush]

I've just modified few more codes in the class generated from tooling wsdl and now its giving me - "System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: INVALID_TYPE: Must send a concrete entity type. faultcode=sf:INVALID_TYPE faultactor="

Request that I've formed now is:

env:Header00D24000000JxJC!AR4AQKVFBz8f81yXxdy_ZrddOFNONhEh5_VNKJGiMfjyW0faAMaUfM0KAEimGnVTnsyHOHbCbQcIfRP3tEWj6zm_hVLr8hFm/env:Headerenv:Body33.0@istest

private class Test_toolingSoapSforceCom {}Test_toolingSoapSforceComtrueTest_toolingSoapSforceComActive/env:Body/env:Envelope

Please could you let me know if I'm doing anything wrong. Thanks in advance for your help.

@dancinllama any thoughts on this?

@tquilapratyush you may in the meantime want to try out the earlier REST based implementation, which was archived in this branch, https://github.com/afawcett/apex-toolingapi/tree/apex-toolingapi-rest

Thanks a lot @afawcett This works like a charm..

To provide more info on my issue:
Intially, I tried something like:
List sObjects = new List();
sObjects = testClassList;
ToolingAPIWSDL.SaveResult[] saveResult = toolingAPI.create(sObjects);
And, then I tried the following, but both of them gave the same exception – Invalid_Type.
List sObjects = new List();
for(ToolingAPIWSDL.ApexClass newTestClass : testClassList) {
ToolingAPIWSDL.sObject_x newSObject = new ToolingAPIWSDL.sObject_x();
String[] tempFieldstoNull = new String[]{};
newSObject.fieldsToNull = tempFieldstoNull; //null
newSObject.Id = null;
newSObject.ApexClass = newTestClass;
sObjects.add(newSObject);
}
ToolingAPIWSDL.SaveResult[] saveResult = toolingAPI.create(sObjects);
