HTTP/1.1 500 Internal Server Error

[gabicavalcante]

Hello,

I'm trying tu run the project, but always I get "HTTP/1.1 500 Internal Server Error".

My code:

import java.io.IOException;
import java.io.InputStream;

import org.opensaml.DefaultBootstrap;
import org.opensaml.xml.ConfigurationException;

import de.tudarmstadt.ukp.shibhttpclient.ShibHttpClient;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient; 
import org.apache.http.client.methods.HttpGet; 
 

public class Main {
	
	private static final String Username = "...";
	private static final String Password = "..."; 
	private static final String IdpUrl = "https://<idp>/profile/SAML2/SOAP/ECP"; 
	private static final String protected_url = "https://<sp>/secure/index.php";  

	public static void main(String[] args) throws ConfigurationException, ClientProtocolException, IOException { 
		DefaultBootstrap.bootstrap();
		
		HttpClient client = new ShibHttpClient(IdpUrl, Username, Password, true);
		
		try {
			HttpGet req = new HttpGet(protected_url);
			System.out.println(req.toString());
			HttpResponse res = client.execute(req);
			
			InputStream output = res.getEntity().getContent(); // returns an InputStream
			System.out.println(output.read());
		} finally { 
	    }
	}

}

My Idp log:

I would love to help, but it has been quite a while since I was working on this. Unfortunately, I have no idea what problem you are running into. However, if you manage to solve it, I would encourage you to post a message here explaining how you did it in case other people run into the same kind of trouble.

Good luck!

When the code try to logging in to the IdP, It does not define the content-type. I added:

idpLoginRequest.addHeader(HttpHeaders.CONTENT_TYPE, "text/xml; charset=utf-8");

And now it's working
