taskdef with classpathref not working
I want to be able to define task's that use either the axis-1_1
or the axis-1_2_1 jars depending upon the value of a property.
The intent is to avoid having users explicitly set their CLASSPATH
before invoking the build. I have found examples such as the following
that appear to be exactly what I want but I have not been able to get
this (or a large number of other variants) to work.
I'm running java 1.4.2 with ant 1.6.0 on linux.
<target name="init_axis-1_2_1" unless="axis.version.1_1">
<echo message="Setting axis.classpath to **/*.jar in
${axis.home}/lib"/>
<path id="axis.classpath">
<fileset dir="${axis.home}/lib">
<include name="**/*.jar" />
</fileset>
</path>
<property name="axis.classpath.string" refid="axis.classpath"/>
<echo message="axis.classpath=${axis.classpath.string}"/>
<taskdef name="axis-wsdl2java"
classname="org.apache.axis.tools.ant.wsdl.Wsdl2javaAntTask"
classpathref="axis.classpath">
</taskdef>
</target>
This runs great, the conditional is triggered correctly, the axis
classpath is
set correctly, but I get the following error upon build.
init_axis-1_2_1:
[echo] Setting axis.classpath to **/*.jar in /opt/jlib/axis-1_2_1/lib

The class is definitely on the classpath.
Anyone know what gives?
Thanks!

Thanks to Steve and Stefan!
In experimenting, I had put the axis-ant.jar in $ANT_HOME/lib
and that was the root of the classloading problem as described
in the faq. I was able to quickly determine this to be the case
by running an "ant -diagnostics".

It looks like axis-ant.jar is being loaded, but part of axis.jar itself
is not being picked up.
Make sure there is no other axis-ant.jar in your classpath (do
-diagnostics) to make sure it hasnt crept in
Other points
-there is a properties file somewhere under org.apache.axis.tools.ant.
that defines all the ant tasks that axis includes
-instead of two targets to set up the path and tasks, you could have one
target which chooses a different axis.home value depending on a switch,
then use that
<condition property="axis.home" value="${axis-1.1.home}">
<istrue "use.axis.1.1" />
</condition>
<property name="axis.home" value="${axis-1.2.home}"/>
<path id="axis.classpath">
<fileset dir="${axis.home}/lib">
<include name="**/*.jar" />
</fileset>
</path>
...etc.
I would also point out that Axis1.3 is newly out, and that I would
really not use axis1.1 in a production system, due to some bugs,
especially its quirky handling of mustUnderstand.

In general, this works. But you need to check very careful which
classes are where. If your task class can be loaded in a classloader
higher up in the classloader hierarchy (like CLASSPATH or
ANT_HOME/lib) then your classpathref will simply get ignored. Read
the FAQ entry <http://ant.apache.org/faq.html#delegating-classloader>
for more details.
