Hello Steve
this problem is the one described here : http://ant.apache.org/faq.html#delegating-classloader I had this happening also with a JNDI implementation class. Are the JSSE interfaces part of the JDK you are using ? I wonder whether a good wording for this type of problems would not be something like : "Classloaders are not reentrant" ? As workarounds : if you use ant 1.6, start ant like this : ant -lib [path to ws jars] with older versions of ant, you will have to set your CLASSPATH to include the jars which you need, then start ant Cheers, Antoine > I am trying to update our build file as we have just upgraded to > WAS5.1 to use the wasdmin task.
