Loading of native libraries in PLJAVA

We are facing 2 problems in loading files from Pljava.

1. Loading Native C library from Pljava trigger.

From Pljava trigger, we were trying to load native library,
Using System.loadLibrary("<library_name>"), which is
specified in the LD_LIBRARY_PATH.

Also specified the library file under /var/lib/pljava where
all the pljava specifc "*.so" files are located, which has an entry in the
postgresql.conf - dynamic_library_path for
"/var/lib/pljava",

Both theses cases failed to load native library.

we are getting this error in both cases-
UnSatisfiedLinkedError

2. Loading Properties file from trigger. (using
Properties.load(<properties_name.properties>))
We are unable to load properties file from
Properties.load("<properties_name.properties>").
we have included properties file in jar file and installed
the jar and set the jar file in the classpath using "sqlj.set_classpath".

Any light on this.

Thnx
