WSDL2Java Task fails to generate src files Caused by:
java.lang.NoSuchMethodException:
javax.xml.bind.annotation.XmlElementRef.required()
-----------------------------------------------------------------------------------------------------------------------------------------
Key: CXF-4239
URL: https://issues.apache.org/jira/browse/CXF-4239
Project: CXF
Issue Type: Task
Components: Tooling
Affects Versions: 2.3.9
Environment: Windows XP, Eclipse Helios, Java 1.6 version
Reporter: SAURABH NIGAM
Priority: Critical
We have a webservice up and running, currently exposed through CXF Simple
frontend. But when we try to generate proxy jar for it using WSDL2Java utility
provided by CXF 2.3,9 version , we are getting some exceptions, which we are
unable to debug further. Please find below the ant build.xml used for
generating the src java files :-
<?xml version="1.0"?>
<project name="cxf wsdl2java" basedir=".">
<property file="./../src/antbuild/eflow_project_windows.properties" />
<path id="cxf.classpath">
<fileset dir="./lib">
<include name="*.jar"/>
</fileset>
</path>
<target name="cxfWSDLToJava">
<java classname="org.apache.cxf.tools.wsdlto.WSDLToJava" fork="true">
<arg value="-client"/>
<arg value="-d"/>
<arg value="src"/>
<arg value="-verbose"/>
<arg
value="http://z1dnd83a.dev.qintra.com:40400/eflow/services/EflowProvisioningServices?wsdl"/>
<classpath>
<path refid="cxf.classpath"/>
</classpath>
</java>
</target>
</project>
The lib directory here being used for cxf classpath has all the libraries from
the CXF 2.3.9 distribution binary.
The exception stack trace we are experiencing is as follows :-

Please guide us as to how to get this issue resolved as we are kind of stuck
due to this issue. It seems that some method is missing while trying to call
through reflection, but since we don't have any java source file as of now, I
am unable to debug it further. This exception we are getting while trying to
generate java proxy src files using WSDL2Java utility from CXF version 2.3.9.
Any help of any sort will be highly appreciated. Please take it as a high
priority, as its blocking our production delivery schedule.
