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.

The problem is not this line:

out2.close();   

The problem can be the SOAP action or the message you are sending.

You can try checking the response code before reading the actual connection input stream (connection.getResponseCode()) and if the response code is not 200 (OK) then instead of the input stream read the connection error stream for more details (connection.getErrorStream()).
