[Ant] How to factorize tasks? (Newbie-question)

I want to factorize two ant targets (deploy/undeploy). The only
difference is that they call a java class with a different parameter
(a wsdd file). Here is a snippet of the working ant build.xml file:

<project name="MyProject" default="compile" basedir=".">
    ...
    <path id="project.adminclient.classpath">
    ...
    </path>


    <target name="deploy">
        <java classname="org.apache.axis.client.AdminClient">
            <arg value="A"/>
            <arg value="B"/>
            <arg value="deploy.wsdd"/>
            <classpath refid="project.adminclient.classpath" />
        </java>
    </target>

    <target name="undeploy">
        <java classname="org.apache.axis.client.AdminClient">
            <arg value="A"/>
            <arg value="B"/>
            <arg value="undeploy.wsdd"/>
            <classpath refid="project.adminclient.classpath" />
        </java>
    </target>

</project>

I thought I could facorize the <java> tag to something like:

<project name="MyProject" default="compile" basedir=".">
    ...
    <path id="project.adminclient.classpath">
    ...
    </path>

    <java id="project.adminclient.execute"
classname="org.apache.axis.client.AdminClient">
            <arg value="A"/>
            <arg value="B"/>
            <classpath refid="project.adminclient.classpath" />
    </java>


    <target name="deploy">
        <java refid="project.adminclient.execute">
            <arg value="deploy.wsdd"/>
        </java>
    </target>

    <target name="undeploy">
        <java refid="project.adminclient.execute">
            <arg value="undeploy.wsdd"/>
        </java>
    </target>

</project>

The call of the <java> tag works but the problem is that the parameter
(wsdd-file) isn't passed to the <java> tag.

Can you say me how one would do this?

Thank you very much!

Here's what I would do to combine common parts of two targets (sorry, I didn't
test this, but you'll get the idea):


<target name="_callAdminClient">
<fail message="No parameter, you probably called this target directly!"
unless="adminclient.third.parameter"/>
<java classname="org.apache.axis.client.AdminClient">
<arg value="A"/>
<arg value="B"/>
<arg value="${adminclient.third.parameter}"/>
<classpath refid="project.adminclient.classpath"/>
</target>

<target name="deploy">
<antcall target="_callAdminClient">
<param name="adminclient.third.parameter" value="deploy.wsdd"/>
</antcall>
</target>

<target name="undeploy">
<antcall target="_callAdminClient">
<param name="adminclient.third.parameter" value="undeploy.wsdd"/>
</antcall>
</target>
