Java2WSDL ant task

[Hollywood]

I have the following snippet in my build.xml file:

<property name="build.dir" value="./build"/>
<property name="src.dir" value="./src"/>
<property name="compile.debug"    value="true"/>
<property name="compile.optimize" value="false"/>

<path id="compile.classpath">
    <pathelement location="./lib/xercesImpl.jar"/>
    <fileset dir="${axis.home}/lib">
        <include name="**/*.jar" />
    </fileset>
</path>

<taskdef resource="axis-tasks.properties" classpathref="compile.classpath"/>

<axis-java2wsdl
    output="./${app.name}.wsdl"
    className="${app.path}${app.name}"
    namespace="${app.namespace}"
    style="DOCUMENT"
    location="${service.location}">
    <mapping namespace="${app.namespace}" package="${app.package}"/>
    <classpath>
        <path refid="compile.classpath"/>
        <pathelement location="${build.dir}/base/${app.path}"/>
    </classpath>
</axis-java2wsdl>

However, it claims it can not find the class file to generate the WSDL from.
Anyone have any thoughts?

Thanks!
