Hi Claude,
Yes, it's possible to use JNI with Servlets, but there are a few things you
must watch out for.
1. The DLL you create must be somewhere on the system classpath (such as in
C:\WINNT\SYSTEM32)
2. The java class which contains the ...native... declarations must be
outside the /servlets/ directory, but still on the servlet engine's
Classpath. (e.g. c:\jclasses) To set this you must consult your servlet
engine's documentation.
3. I am still having problems with the 'small differences - big
implications' factor. Things which work fine in a Java application often
give trouble when transported to a servlet.
I presume it's possible to write JNI DLLs in other languages than C/C++, but
never considered doing that. You could get away with knowing less C, but
then it depends on your application. How would I fare in France not knowing
French?
I hope that helps,
Mark Foley
