Can't really tell from that stack trace.
Try dumping the stack of the root cause. Something like:
  exception.getRootCause().detail.printStackTrace()

It could mean that the server hasn't completed startup yet.
To determine when the server is accepting connections, configure
$OPENJMS_HOME/config/log4j.xml with the following:

  <category name="org.exolab.jms.server.net.RemoteServerConnector"
additivity="false">
    <priority value="INFO"/>
    <appender-ref ref="STDOUT"/>
  </category>

To find out what the embedded connector is doing, add:

  <category name="org.exolab.jms.net.vm" additivity="false">
    <priority value="DEBUG"/>
    <appender-ref ref="STDOUT"/>
    <appender-ref ref="openjms"/>
  </category>

You may also need to add:
  <category name="org.exolab.jms">
    <priority value="WARN"/>
    <appender-ref ref="STDOUT"/>
    <appender-ref ref="openjms"/>
  </category>
