Hi, I took a look at your code.
It looks good. Since the *.h headers from OSG and VPB DLLs are not intended for java JNI invocation, I see that your code has built is own DLL which in turn uses the OSG runtimes. I am taking this similar approach -- as follow... Since I want to do what osgdem.exe does but want to make that accessible from a java application, I wrote a C DLL on Windows that is invoked by my java class. When that DLL has all the includes and DLL lib imported linked to it (same build dependency as osgdem.exe -- but it is a DLL instead of a EXE), the java class can invoke that function in that DLL -- i put some test code in that DLL. Then I copied most of the code from osgdem.cpp into the main function of my DLL. I re-initialize the arguments etc from my entry point so that it mimics osgdem.cpp as much as possible -- at least at this version. Now, when I invoke my DLL which should do the same essential thing that osgdem.exe does, it encounters a java hotspot exception access violation. here is the content of that log file it is generated by jvm.
