I used a program below to test webservices:

public class TestWS {

/** Main method launched from CLI
 * @param 1st parameter provides URL 2nd location of file, content type is calculated upon extension
 * 'application/soap+xml' is used for sxml files
 * @return 0 to OS if completed successfully, otherwise 1
 * Response from HTTP server is printed on console
 */
public static void main(String[] _args) {
System.out.println("TestWS     Copyright (c) 2006 D Rog.");
if (_args.length != 2) {
System.err.println("Invalid number of arguments\n Use: TestWS URL file_location");
System.exit(1);
}
FileInputStream is = null;
HttpURLConnection con = null;
try {
is = new FileInputStream(_args[1]);
con = (HttpURLConnection)new URL(_args[0]).openConnection();
con.setRequestProperty("Content-type", getType(_args[1]));
con.setRequestProperty("SOAPAction", "Some-URI");
con.setDoOutput(true);
OutputStream os;
AroundData.copyStream(is, os = con.getOutputStream());
os.flush();
if (con.getResponseCode() == con.HTTP_OK) {
AroundData.dumpStream(System.out, con.getInputStream());
} else
System.err.println("Response code: "+con.getResponseCode());
} catch(Exception e) {
e.printStackTrace();
} finally {
try {
con.disconnect();
is.close();
}catch(Exception e) {}
}
}


public static String getType(String _name) {
if (_name.endsWith(".xml"))
return "text/xml";
if (_name.endsWith(".sxml"))
return "application/soap+xml";
if (_name.endsWith(".htm") || _name.endsWith(".html"))
return "text/html";
if (_name.endsWith(".txt"))
return "text/plain";

return "application/byte-octet";
}
}

Hi D Rog,
Thanks for your reply,
but could you please tell me what is AroundData here
"AroundData.copyStream(is, os = con.getOutputStream())"

Thanks

Try using Jakarta Commons HTTPClient. Search in google: post xml HttpClient
It's quite easy.

           // Create the HTTPS Client
            HttpClient httpclient = new HttpClient();
            // creates the post method to use.
            PostMethod post = new PostMethod( this.getTargetUrl() );
 
            post.setRequestEntity( new StringRequestEntity( yourXmlRequest ) );
            // Specify content type and encoding
            // If content encoding is not explicitly specified
            // ISO-8859-1 is assumed
            post.setRequestHeader(
                    "Content-type", "text/xml; charset=ISO-8859-1");
            // execute method and handle any error responses.
            httpclient.executeMethod(post);
 
            // read the response
            InputStream in = post.getResponseBodyAsStream();
 
            reader = new BufferedReader( new InputStreamReader( in ) );
            String line;
            StringBuffer buffer = new StringBuffer();
            while( ( line = reader.readLine() ) != null ) {
                buffer.append( line );
                buffer.append( "\n" );
            }
            // clean everything
            reader.close();
            //Now 'buffer' contains the resonse.
