Hi, I am a newbie to Web Services and am trying to build a Web Service that is capable of receiving a XML data file. I am using JBoss 4.02 and JDK 1.5. When trying to build the HelloWorld example as shown in one of the tutorials, I got a NullPointerException for the DIIClient. Searching on these forums, I found it to be a bug JWS187. Is there any way to keep my current versions of JBoss and JDK and get past this bug? Also, could anyone please point me in the right direction (links, tutorials etc) for sending attachments in Web Services and dynamically validating XML data? Any help would be greatly appreciated.
