nice article!
and ... what about invoking web services?
is there a lightweight process to invoke and receive messages without dealing with the "dirty" xml/soap/etc code?
bye!

Frank, in the article you say:

"Generate Web service artifacts, including a WSDL file, by applying annotations to that source file. This step is performed with the help of the apt tool, which is part of JDK 1.5."


How can you generate WSDL from source file? Specifically, the type section of the wsdl that would need the schema of the serialized object. I don't see how this could be ever done by APT-ing the source files.

Hi,

I use JWSDP 2 to compile this sample program. But, I've got the following error when I compile the server:

Can somebody tell me how to fix the error?

Thank you in advance,

it is a bug and root cause is that some lib files are not added in the war. check , properties->build->packaging, those files should be seen war content table, otherwise add it manaually.
