Hi Everyone,
Axis 2 1.0 Release, cygwin, java 1.5.0_05-b05.
I'm attempting to run WSDL2Java.sh and I'm running into an NPE. The wsdl is
actually broken up into a ton of different files, so I'm not sure if that is
contributing to my error or not. I'm afraid I've included a ton of diag
info in the email - please feel free to tell me to take a long walk off a
short pier - all apologies.
Anyway, I've gathered some data from Eclipse. I can't determine if I'm
running into a bug, or just poor WSDL. I placed a breakpoint at line 595 in
org.apache.axis2.description.WSDL2AxisServiceBuilder which is where the NPE
originates. It appears that the Input of my Operation's have null Messages.
I have 8 Operations, and all of them have null Messges. I have some info
from eclipse:
Stack:
Thread [main] (Suspended (breakpoint at line 595 in
WSDL2AxisServiceBuilder))

boolean)

The message field is null, so an NPE is thrown at line 595:
