ejbjar fails when behind firewall/proxy server

[Tim Dawson]

this works fine when working at one location, which doesn't use a proxy
server...

    <ejbjar srcdir="${classes.source}"
            descriptordir="source/com/wamnet/wap/server"
            basejarname="wap-ejb">

      <weblogic destdir="${staging.dir}"
 
classpath="${weblogic.home}/classes;${weblogic.home}/lib/weblogic.jar;${clas
ses.source}"/>
      <include name="ejb-jar.xml"/>
      <exclude name="weblogic-ejb-jar.xml"/>

but from another location which DOES  use a proxy server, I get THIS:

BUILD FAILED

Any ideas how I can get around this?

Thanks,
