Java Question

Why this Ant/Ivy integration of CXF WSDLToJava does not work?

I would like to use

WSDLToJava
of Apache CXF in my Ant buildfile to create Java code from a WSDL. The dependencies are resolved using Ivy. I always get the following error:

WSDLToJava Error: Could not find jaxb databinding within classpath


I do not have an installation and want to use Ivy to do the job for me. Here is the part of my Ant buildfile:

<target name="generate" depends="init">
<ivy:retrieve conf="build"/>
<mkdir dir="${basedir}/target/generated"/>
<ivy:cachepath pathid="build-classpath" conf="build"/>
<java classname="org.apache.cxf.tools.wsdlto.WSDLToJava" fork="true">
<arg value="-d"/>
<arg value="${basedir}/target/generated"/>
<arg value="-client"/>
<arg value="${basedir}/src/schema/MyWebService.wsdl"/>
<classpath refid="build-classpath"/>
</java>
</target>


I use Java 6, Ant 1.8, Ivy 2.2.0 ant CXF 2.2.12. In the Ivy module I configured the following:

<configurations>
<conf name="build" visibility="private"/>
...
</configurations>

<dependencies defaultconfmapping="*->default">
<dependency org="org.apache.cxf" name="cxf-tools-wsdlto-frontend-jaxws" rev="2.2.12" conf="build"/>
<dependency org="org.apache.cxf" name="cxf-rt-databinding-jaxb" rev="2.2.12" conf="build"/>
...
</dependencies>


Where is the problem? Maybe there is a dependency missing, but which one? Without Ivy, the Ant integration uses a classpath with all jars of the CXF installation. If I do so, it works.

In the output of the build I see the following:

There is a cxf-tools-wsdlto-databinding-jaxb dependency that you likely need as well. For a variety of reasons, the tooling and runtime are separate for JAXB.
