glibc-2.3.2

My actual LD_LIBRARY_PATH:
root at newbie:~# echo $LD_LIBRARY_PATH
/usr/lib/jdk1.5.0_02/jre/lib/i386/client:/usr/lib/jdk1.5.0_02/jre/lib/i386:/usr/lib/jdk1.5.0_02/jre/lib/i386/native_threads

I've upgraded the jdk:

root at newbie:~# java -version
java version "1.5.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)
Java HotSpot(TM) Client VM (build 1.5.0_02-b09, mixed mode, sharing)

Thomas, i've installed pljava by the source and the error now is:

ERROR:  attempt to redefine parameter "pljava.vmoptions"

See my postgresql.conf

<cut>
# define "pljava" as a custom variable class. This is a comma separated
# list of names.
#
custom_variable_classes = 'pljava'

# define the class path that the JVM will use when loading the
# initial library. Only meaningful for non GJC installations
#
pljava.classpath = '/downloads/pljava-1.1.0b1/build/pljava.jar'
pljava.classpath = '/usr/local/pgsql8/lib/postgresql.jar'

# Set the size of the prepared statement MRU cache
#
pljava.statement_cache_size = '1'

# If true, lingering savepoints will be released on function exit. If  
false,
# the will be rolled back
#
#pljava.release_lingering_savepoints = true

# Define startup options for the Java VM.
#
pljava.vmoptions = '-Xmx64M -Dbackchannel.port=48'

# Setting debug to true will cause the postgres process to go
# into a sleep(1) loop on its first call to java. This is
# only useful if you want to debug the PL/Java internal C code.
#
pljava.debug = true
</cut>



Thanxs!
