Thanks Matt,
I did make sure to use the Java 1.4 JDK prior to posting. I've created a
simple application that only loads the dll. I've removed all the code from
my .cpp file except the DllMain method and the simple application does not
crash. However, if I add a method to the .cpp file that accesses the
NetView code, i.e. OVwInit() or OVwGetAppName(), the program crashes (even
though the methods are not called) with the error previously reported. I'm
troubleshooting now to see if I can figure out what is going on.
Have you integrated an application using Java 1.4? Just curious if anyone
else already has done this. Also, I have NetView running on two different
machines and when the program is started, without my application, it starts
a Java process. We install the 1.4 JRE that our application uses. Could
there be a conflict between the JVM NetView uses and the one my application
uses?

This may be an obvious answer but I would recommend you ensure that you
build your dll using Java 1.4 JDK... just to ensure that the headers
haven't changed or anything of that sort..

Integrating Java Applications using Java 1.4
01/15/2003 07:47 PM
Hi,
Has anyone tried to integrate a Java 1.4 application with NetView? I have
a
Java application that uses JNI to communicate with NetView. The code
builds
and runs fine using Java 1.3 but if I change to Java 1.4, I am unable to
load my .dll library. Below is the error occurs when the application runs.
Thanks,
Ken Stoutzenberger
