Subject [jira] Created: (AXIS2-1867) NullPointerException generating WSDL with anonymous simple types
Date Wed, 13 Dec 2006 09:45:20 GMT
NullPointerException generating WSDL with anonymous simple types
----------------------------------------------------------------

                 Key: AXIS2-1867
                 URL: http://issues.apache.org/jira/browse/AXIS2-1867
             Project: Apache Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: codegen
    Affects Versions: nightly
         Environment: Axis2 1.1.1-SNAPSHOT (nightly build), JDK 1.5.0_08 x64, Windows XP x64
            Reporter: Peter Runge


WSDL2Java is failing on a WSDL that has multiple anonymous simple types with a NullPointerException.

This may be related to issue AXIS2-1780, however this WSDL was tried with the latest nightly
build (built 2006-12-13).

The following is output of the error with the nightly build.  The same error occurs with Axis2
1.1.

It seems that removing one of the anonymous simple types allows the code to be generated without
error.

The following WSDL was used (simplest form of original to reproduce bug):
