The easiest way to get thread dumps is for one to use JDK 1.5 or above on the server.  Make sure the JDK'x JMX MBean Server is turned on and that you've set the switches to allow for remote JMX connections..

enable jmx remote switch = "-Dcom.sun.management.jmxremote"
remote jmx port = "-Dcom.sun.management.jmxremote.port=SOMEPORTNUM"
disable remote auth = "-Dcom.sun.management.jmxremote.authenticate=false"

Install JCONSOLE on a workstation somewhere (preferably 1.6), download the JTA Plugin (Thread Dump Analyzer JCONSOLE Plugin) from https://tda.dev.java.net/ - then you should be able to perform thread dumps remotely.
