Java VM conflict on start with running VM in Browsers

Thread view:

Hello Everyone,

I have a module linked with Netscape/Mozilla-Browsers.

In this module I start a JVM via the JNI interface.

When this VM is running and I want to load an Applet in the Browser, I
get the message that an error occured while connecting to a running
JVM.

With the affect that the applet cannot be loaded.

What can I do to find the right connection between the two VMs?

Or how can I start the JNI-VM to avoid the above mentioned.

thanx in advance
Sebastian

I'm afraid it is not possible to start two VMs in the same process. See
http://java.sun.com/j2se/1.4.2/docs/guide/jni/spec/invocation.html.

"JDK 1.1.2 does not support creating more than one VM in a single process."
AFAIK, this still holds.

What you could do in your plugin, is _find_ the Java plugin's VM instead of
creating a new one. That would require starting an applet first.
