[Resin-interest] class loader question on linux?
I wonder if someone on the list has an idea as to what to try in this situation.
I used to in resin 2.x use the "class loader hack" config, not sure now why. I
now have potentially a class loader issue loading native code, but ... no hints
I get from logs.
The code bellow I am using, works great in Resin nightly on windoze in the
container. It works great on Linux (Fedora 7) in Java outside of resin servlet.
But it fails to ... parse when inside the resin container, it just returns
blank and no traces or logs.
One time it said:
UnsatisfiedLinkError: Native Library already loaded in another
classloader
But no errors anymore show up. In any case I moved needed loading jars to
resin/lib and .so files are in LD_PATH and CLASSPATH.
I wonder what I should try to debug? Anyone?
Even if there's a link on the resin 3.x classloader "hack" if any, or .. a link
to educate me more on native java integration or on how to hook up remote resin
to debug,jconsole,jmx or to slap me for a something silly.
There is some google on resin's class loader and on the error I got above once
but not more. Again works on Windoze and on linux outside of the container

Hey, the compilation works just fine here. If you want to compile resin itself, then use ant to build it.
