Java HotSpot Virtual Machine

Hi I am having a bit of trouble setting the correct classpath for jar files in JNI.

I have a standalone Java class

myClass

which uses a jar file

mjar.jar

. This class can be used from a main "mainClass fine.

myClass

builds fine

I make and build the

mainClass

using a batch file.

SET ROOT_DIR=D:\myDocs
SET CP=.
SET CP=%CP%;%ROOT_DIR%\myjar.jar
javac -g -classpath %CP% mainClass.java

SET ROOT_DIR=D:\myDocs
SET CP=.
SET CP=%CP%;%ROOT_DIR%\myjar.jar
java -classpath %CP% mainClass

All that works fine.

However when I reuse myClass in a JNI c file, the JNI cant find the class. There is not a problem with the origional JNI code as If I remove the jar stuff in

myCLass

, the JNI code finds the myClass and workes fine.

So the problem is that I am unsure how to set the class path for JNI code in C to find/include the Jar files
