Subject <java fork="true"> does not detect process termination
Date Mon, 23 Aug 2004 14:59:06 GMT
Hi,

I start a weblogic managed server with the following target:

<target name="startwlm" if="server.name" depends="init-wl">
  <java classname="weblogic.Server" fork="yes" dir="${applications.dir}/.."
>
    <sysproperty key="java.library.path" path="${weblogic.home}/bin"/>
    <classpath refid="weblogic.class.path"/>
    <jvmarg line="${weblogic.jvm.args}"/> 
    <jvmarg value="-Dbea.home=${bea.home}"/> 
    <jvmarg value="-Dweblogic.Domain=${weblogic.domain.name}"/> 
    <jvmarg value="-Dweblogic.Name=${server.name}"/> 
    <jvmarg
value="-Dweblogic.management.username=${weblogic.server.username}"/> 
    <jvmarg
value="-Dweblogic.management.password=${weblogic.server.password}"/> 
    <jvmarg
value="-Dweblogic.management.server=${weblogic.server.host}:${weblogic.serve
r.port}"/> 
    <jvmarg value="-Ddomain.dir=${weblogic.domain.dir}"/>
    <jvmarg
value="-Djava.security.policy=${weblogic.home}/lib/weblogic.policy"/> 
  </java>
</target>

In order to shutdown this process, I call an other target like this:

<target name="stopwlm" if="server.name" depends="init">
  <taskdef resource="net/sf/antcontrib/antcontrib.properties"/> 
  <propertycopy name="port" from="${server.name}.port"/>
  <java classname="weblogic.Admin" fork="yes" dir="${applications.dir}/..">
    <sysproperty key="java.library.path" path="${weblogic.home}/bin"/>
    <classpath location="${weblogic.home}/lib/weblogic.jar"/>
    <arg line="-url ${weblogic.server.host}:${port}"/> 
    <arg line="-username ${weblogic.server.username}"/> 
    <arg line="-password ${weblogic.server.password}"/> 
    <arg value="SHUTDOWN"/> 
  </java>
</target>

The weblogic server instance shuts down correctly (the process ID
disappears) but the ant process that ran startwlm does not return and
continues waiting. This problem exists in ant 1.5.3 and 1.6.2.

I do the same thing with the admin server and it works fine.

Does anyone have an idea of what I am doing wrong here?

Thanks in advance,

Patrick.
