Jayachandra, thanks for your info and time. But I have never had lock to
make things going. Here is my code:
package ws.Echo;
public interface Echo
{
public String echoString(String arg);
public String echoString_double(String arg1, String arg2);
}

When I use tcpmoni to see the soap code, it seams to me that the client
side code
is fine and I did see string "10" and "12" passed in the envelope. But
on the server size, I couldn't see the string "12", it was null. And the
tomcat server displayed
the following errors:
java.io.NotSerializableException: ws.Echo.EchoImpl

P.S. Could you zip your entire code and send to me so I can make
comparison between your and mine?
