Bug when using both Jpcap + jFreeChart Libs

[Bentow]

Hello Everybody,

I'm involved in a project using JpCap and Graphs.
When I run my JPCAP application solely, it works just fine. But, when
I add the jFreeChart + jCommon libraries to the classpath the
following error appears on screen:
--
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jpcap in
java.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)
at jpcap.JpcapCaptor.<clinit>(JpcapCaptor.java:251)
at core.ThreadRTP.main(ThreadRTP.java:82)
--

I filtered the error so I know it happens only when I add both
libraries, if don't include them, it works just fine.
Did anyone have problem with this, or something similar?

Cheers

Solved!!!

I don't know why, but after I add these 2 libraries, I need to
explicitly put into the VM arguments:
-Djava.library.path=c:\windows\system32\

Crazy java eheheh

Cheers.

This raises many questions. How was the code finding the DLL before you
added the other libraries? Where did you add them? What classpath? Are
there multiple versions? Are any in extension directories?
