I was having the same error today on linux, and happened to do an 'ldd' on
'libpljava.so'

As I recall, it has a dependency on libjvm.so, but the installation of Java
had not told the system where to find either the server or client version of
libjvm.so, so I put a symbolic link to the libjvm.so version I wanted to use
in the '/lib' directory and the error went away.

I'm not sure if that is the right solution, but it seems to have worked so
far.

Howdy,
    I'm having a bit of trouble installing PL/JAVA.  I believe I've the
LD_LIB and CLASSPATH variables correctly, but I'm still getting the
error about libjvm.so:
---------------
java.sql.SQLException: ERROR:  could not load library
"/usr/lib/postgresql/libpljava.so": libjvm.so: cannot open shared object
file: No such file or directory
---------------

I believe I'm setting both CLASSPATH and LD_LIBRARY_PATH correctly for
my machine.  Can you think of any reason why this error might occur?

Below is the output of the init script to start postgres.

Many thanks,

Eric
