Tim,

I tried deploying directly to Geronimo as you advised. I found I could
republish multiple times if Geronimo had been started directly and not by
Eclipse. This led me to carefully examining the ps traces running outside
eclipse and under eclipse.

By moving the JVM parameters to the start of the Eclipse input box I solved
the problem. I think the problem was that I had inserted these parameters
immediately before the closing ". I think these parameters were not getting
through to the JVM invocation.

Thanks for your help,

Steve
