There is only a 32 bit JVM on the machine. The bridge dll has not been
recompiled since
mid '08. If it was an incompatibility with the Microsoft Runtime Library
wouldn't you expect
the Service Version to do the same ?
If you look at the code you will see I try to create a file on the
root of the C drive (remotedebug.txt) and
The file does get created via the Service but not standalone, weird. If it
was crashing
as a result of the file creation, would you expect to see the CPPinit at the
top
of the stack trace ?
Thanks again

Subject: Win7 calling native code via JNI
as soon as I call the dll's init function
(CPPInit) it crashed the JVM.
Are you using the same JVM when you run Tomcat as a service? The one in
this crash is the 32-bit client, but you're on a 64-bit platform, and I
wouldn't be surprised that the service is using a 64-bit server JVM
(assuming you have one installed).
It wouldn't even get that far if he tried to load a 32-bit dll in a 64-bit
JVM.
My guess is an incompatibility in the MSVCRT.dll versions. If you compile
the JNI dll with a newer version of MSVC, then you can see weird crashes
like this.
If you look at the code you will see I try to create a file on the
root of the C drive (remotedebug.txt) and
Does the account you're running on have permission to do that? (Win7 is
a tad picky about things like that.)
