[Axis2] NoClassDefFoundError while using WSDL2Java

[Jozef Krssak]

Hi all
I am trying to migrate our code based on Axis to Axis2 and I am generating
java classes from WDSL.
I am getting the following exception:

2007-10-04 10:25:12,199 344   DEBUG [
org.apache.axis2.wsdl.codegen.CodeGenerationEngine] (main) Extension class

    at org.apache.axis2.wsdl.WSDL2Java.main(WSDL2Java.java:24)


To get more information about extension class name I have done small change
in CodeGenerationEngine.getObjectFromClassName() to see content of parameter
className. The exception happens when JaxMeExtension is loaded:

I am able to get java classes (even if I have still other problems to
include this Axis2 code into our existing project without compilation
errors) but I am not sure if this exception can harm any generated java
code. Maybe this information will be usefull for someone to fix it. I could
not find "org/apache/ws/jaxme/generator/SchemaReader" or "
org.apache.ws.jaxme.generator.SchemaReader" in Axis2 sources.

For full information I have tested it with Axis2 1.3 and last nightly build
and my WSDL2Java options are:

                <java classname="org.apache.axis2.wsdl.WSDL2Java"
fork="true">
                    <classpath refid="axis.cp"/>
                    <jvmarg value="-Daxis2.jalopy=false"/>
                    <arg value="-uri"/>
                    <arg file="@{file}"/>
                    <arg value="--output"/>
                    <arg file="${generated.dir}"/>
                    <arg value="--databinding-method"/>
                    <arg value="adb"/>
                    <arg value="--unpack-classes"/>
                    <arg value="--unwrap-params"/>
                    <arg value="--noBuildXML"/>
                </java>


Thanks
