I have problem using pljava-1.1.0 and PostgreSQL 8.0.3 for Compiere-2.5.2
on Redhat Enterprise Linux AS 4 Intel 32 bit.

Here are the command and error message:

3) installed pljava-src-1.1.0.tar.gz:
# export PATH=/opt/SUNWappserver/jdk/bin:$PATH
# export JAVA_HOME=/opt/SUNWappserver/jdk
# tar zxf pljava-src-1.1.0.tar.gz
# cd pljava-1.1.0

lrwxrwxrwx 1 root root 16 May 22 00:10 libpljava.so -> libpljava.so.1.1

4) Updated postgresql.conf:
# grep pljava.classpath /var/lib/pgsql/data/postgresql.conf
pljava.classpath = '/home/zoong/JDK/pljava-1.1.0/build/pljava.jar'

Also tried with:
pljava.classpath = '/home/zoong/JDK/pljava-1.1.0/build'

# ls -l /home/zoong/JDK/pljava-1.1.0/build/pljava.jar
-rwxr-xr-x 1 root root 126271 May 22 00:10 /home/zoong/JDK/pljava-1.1.0/build/pljava.jar

# grep dynamic /var/lib/pgsql/data/postgresql.conf
dynamic_library_path = '$libdir:/usr/lib/pgsql:/usr/lib:/home/zoong/JDK/pljava-1.1.0/build:/home/zoong/JDK/pljava-1.1.0/build/objs'

5) started PostgreSQL:
su - postgres
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/SUNWappserver/jdk/jre/lib:/usr/lib:/usr/lib/pgsql:/opt/SUNWappserver/jdk/jre/lib/i386:/opt/SUNWappserver/jdk/jre/lib/i386/client:/opt/SUNWappserver/jdk/jre/lib/i386/native_threads
$ export PATH=/opt/SUNWappserver/jdk/bin:$PATH
$ export JAVA_HOME=/opt/SUNWappserver/jdk
$ pg_ctl start -D /var/lib/pgsql/data -l logfile -o "-i"

6)
# ldd /usr/lib/libpljava.so
libjvm.so =>
/opt/SUNWappserver/jdk/jre/lib/i386/client/libjvm.so (0x009b2000)
libc.so.6 => /lib/tls/libc.so.6 (0x004e8000)
libnsl.so.1 => /lib/libnsl.so.1 (0x002cc000)
libm.so.6 => /lib/tls/libm.so.6 (0x0069b000)
libdl.so.2 => /lib/libdl.so.2 (0x00111000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x001a0000)
/lib/ld-linux.so.2 (0x008ec000)

Any help would be very appreciated.
