Hi, >Have you tried synchronizing access to the native methods? Yes. >Does Tomcat and the JVM crash when you only have one servlet using the native code? Yes, everything crashes when the first servlet gets the instance of shared object. Lets say the shared object is called Data. The servlet gets the Data instance by "Data data = Data.getInstance();" and in Data object it looks like this: "private static Data instance = new Data();" and then the getter method. Data in it's constructor tries to get access to Tibco Rendezvous and create a session. And exactly at this moment everything crashes.
>Alternatively, can you have two instances of the object so that it is not shared? No, i need to have it like this. This shared object gets the data, which is then shared among other servlets. >What are the messages printed by the JVM when it crashes?

It looks like. JVM says it's loaded. See the crash message. I've marked the suspected library. BTW, i've patched the system as it was suggested by sun. The funny thing is that it runs without any problems if used without Tomcat.
