Java2WsdlAntTask cannot be found using the classloader AntClassLoader

[Kumar Raja]

Hi All,

I'm not sure, if this needs to be posted to Webservices forum or here, but since this is related to build.xml, I thought of putting my question here.

I have a project as below

HelloWorld
|
| ------- src (All my source code)
| ------- lib (All required axis 1.x jar files )
| ------- build (All compiled class files)
|------ build.xml (this is directly under HelloWorld)

Snippet from my build.xml is as follows

    
          <project name="HelloWorld" basedir="." default="generateWSDL">  
   
  <property name="conf.dir" location="${basedir}/conf" />  
  <property name="build.dir" location="${basedir}/build"/>  
  <property name="classes.dir" location="${build.dir}/classes" />  
  <property name="compile.src" location="${basedir}/src" />  
  <property name="lib" location="${basedir}/lib" />  
  <property name="wsdl.dir" location="${build.dir}/wsdl" />  
  <property name="wsdd.dir" location="${build.dir}/wsdd" />  
  <property name="java.home" location="C:/DevCenter/Sun/jdk" />  
  <property name="jboss.home" location="C:/DevCenter/jboss" />  
  <property name="axis.home" location="C:/DevCenter/axis-1_4" /> 

<path id="classpath">  
   <pathelement path="${java.home}/lib/*.jar" />
   <pathelement path="${jboss.home}/client/*.jar" />     
   <pathelement path="${axis.home}/lib/*.jar" />     
   <pathelement path="${lib}/*.jar" />     
   <pathelement path="${classes.dir}" />  
  </path>  
  
   
   
 <taskdef name="axis-java2wsdl" classname="org.apache.axis.tools.ant.wsdl.Java2WsdlAntTask" >  
         <classpath refid="classpath"/>  
 </taskdef>  
   
 <taskdef name="axis-wsdl2java" classname="org.apache.axis.tools.ant.wsdl.Wsdl2javaAntTask" >  
          <classpath refid="classpath"/>  
 </taskdef>

<target name="generateWSDL" description="Generates wsdl files from the java service interfaces">  
  <mkdir dir="${wsdl.dir}"/>  
  <axis-java2wsdl classpathref="classpath"  
           output="${wsdl.dir}/HelloWorld.wsdl"  
           location="http://localhost:8080/axis/services/HelloWorld"  
           namespace="http://myservices.com"  
           classname="org.myapp.hello.HelloWorldService">  
     <mapping namespace="http://myservices.com" package="org.myapp.hello"/>  
  </axis-java2wsdl>  
 </target>  
   
 <target name="generateWSDD" description="Generates wsdd files from the wsdl files">  
  <mkdir dir="${wsdd.dir}"/>  
  <axis-wsdl2java  
        output="${wsdd.dir}"  
        deployscope="Application"  
        serverside="true"  
        url="${wsdl.dir}\HelloWorld.wsdl">  
  </axis-wsdl2java>  

As evident from the build.xml, I'm trying to use ant tasks for generating WSDL and other artifacts using axis implementation. But my problem is, it won't run. When I run ant against this build.xml, I see the below error message

    
taskdef class org.apache.axis.tools.ant.wsdl.Java2WsdlAntTask cannot be found using the classloader AntClassLoader[C:\DevCenter\HelloWorld\build\classes]

Is there anything I'm missing here. Do I need to have any other jars in my classpath.

Please advice.

You probably need to add the JAR that contains that ANT task to the CLASSPATH that ANT runs with yes.

When you define the 'classpath' - you need to use <fileset ...> instead of <pathelement... >

e.g.

<path id="classpath">
   <fileset dir="${axis.home}/lib">
      <include name="**/*.jar" />
   </fileset>
   <fileset dir="${jboss.home}/client">
      <include name="**/*.jar" />
   </fileset>
   ...
   ...
   <pathelement path="${classes.dir}" />
</path>
