Invoking webservice- Server returned HTTP response code: 500

[purnima Nair]

I am trying to invoke webservice from jsp.
URL url = new URL(SOAPUrl);
URLConnection connection = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection) connection;

byte[] b = reqXml.getBytes();

httpConn.setRequestProperty( "Content-Length",
String.valueOf( b.length ) );
httpConn.setRequestProperty("Content-Type","text/xml; charset=utf-8");
httpConn.setRequestProperty("SOAPAction",SOAPAction);
httpConn.setRequestMethod( "POST" );
httpConn.setDoOutput(true);
httpConn.setDoInput(true);

OutputStream out2 = httpConn.getOutputStream();
out2.write( b );

out2.close();

// Read the response and write it to standard out.
InputStreamReader isr =new InputStreamReader(httpConn.getInputStream());

When it reaches the above line httpConn.getInputStream() it throws the error
java.io.IOException: Server returned HTTP response code: 500 for URL:
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1313)

Due to this,response is not generated and webservice methods are not called.What could be wrong?Please help.

Regards,

Problem may be this line

 out2.close();  

You should never close a connection until you have also handled the matching input stream. You can flush() to ensure the entire request is sent.

The close will close both sides of the connection.
