Null pointer exception in WSDL2C compiling schema when generating ADB
---------------------------------------------------------------------
Key: AXIS2C-768
URL: https://issues.apache.org/jira/browse/AXIS2C-768
Project: Axis2-C
Issue Type: Bug
Components: wsdl2c tool
Affects Versions: Current (Nightly)
Environment: Windows XP
Reporter: Bill Mitchell
When I attempt to generate C bindings for the WSDL file below, the WSDL2C
utility fails with a null pointer exception without generating any stub code
whatsoever.
The exception trace is:
>java org.apache.axis2.wsdl.WSDL2C -or -d adb -wv 1.1 -u -uri service.wsdl
Retrieving document at 'service.wsdl'.

I receive this failure both with the WSDL2C released in Axis2-1.3 and in the
current nightly build I downloaded yesterday. Of course, it is a little
difficult to isolate what in the WSDL is causing the failure, as no stub code
is generated that might hint at the problem area. The same WSDL is accepted by
the Axis2 WSDL2Java utility, so the issue is specific to C code generation. As
the WSDL2Java utility accepts the file, this suggests that the WSDL itself is
valid. If -d none is specified on the command line, the WSDL2C utility runs to
completion, so the issue is specific to the generation of the C data bindings.
