[Pljava-dev] [Fwd: Unable to load class org/postgresql/plsql/internal/Backend]

Here is my dynamic_library_path in postgresql.conf
dynamic_library_path =
'/usr/lib64/:/home/java/j2sdk1.4.2/jre/lib/amd64/server/'

Note that I am running an AMD64 so things will look slightly different.
The key in this line is that this path points to a directory that
contains a file called libjvm.so. In some JVM's I have seen that file
under jre/lib/client (rather than /server)

Here is what my LD_LIBRARY_PATH looks like:
LD_LIBRARY_PATH=/usr/lib64/:/home/java/j2sdk1.4.2/jre/lib/amd64/server/
export LD_LIBRARY_PATH

In my case the pljava build placed pljava.so.1.1 in /usr/lib64 and
created soft links with the proper file name of pljava.so

Also, you may run into another problem once you get past the library
path issue. I was unable to install pljava using a 1.5.x JDK. I ended up
using Blackdown 1.4.2. It has something to do with being able to spawn a
VM from within Postgres. I don't remember exactly.

Finally, I'm serious about restarting postgres. I did two installations
where the path settings were right but I had to restart postgres before
I could successfully add pljava as a language in the database.
