Trying to call a webservice which has Basic Authetication. I am passing in the valid crediantials but some how getting status 500 at getExecuteMethod(). Does this mean call to the webservice successful?? Please help.. Its very urgent..
HttpClient client = new HttpClient();
 

			// pass our credentials to HttpClient, they will only be used for

			// authenticating to servers with realm "realm" on the host

			// "www.verisign.com", to authenticate against

			// an arbitrary realm or host change the appropriate argument to null.

			client.getState().setCredentials(

				new AuthScope(

					AuthScope.ANY_HOST,

					AuthScope.ANY_PORT,

					AuthScope.ANY_REALM),

				new UsernamePasswordCredentials(

					userName,

					password));

	

	

	

	

			// create a GET method that reads a file over HTTPS, we're assuming

			// that this file requires basic authentication using the realm above.

			post = new PostMethod(url);

					

			post.setDoAuthentication(true);
 

			RequestEntity entity = new StringRequestEntity(soapRequest);

			post.setRequestEntity(entity);

			

			

			ILogger.ITimer t = getLogger().createTimer();

			

	

			//	timer.setAutoReset(true);
 

			status = client.executeMethod(post);

			 if (status != HttpStatus.SC_OK) {

			 	System.err.println("Method failed: " + post.getStatusLine());

			 }
 

Here is the log file info:

[7/14/09 21:19:56:206 EDT] 00000027 AuthChallenge I org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme basic authentication scheme selected

I don't think getting 500 response code has to do with
(in)valid credentials. You get an error "Not Authorized"
when the credentials are not valid.

This means that the XML you are sending to server doesn't
have valid syntax.

HttpClient, btw, is not the first choice for a web service client. While it can work as one afaik, you would be better off using something like Axis

This helped to resolve the problem as i missed backslash to one of the tags used in my XML passing using HttpClient.
