Hi Tim,
It seems you have either a CLASSPATH environment variable or the 
postgresql.conf variable 'pljava.classpath' setup so that the System 
Classloader makes attempts to read the log4j-1.2.13.jar file. Please 
make sure that:

a). No CLASSPATH environment variable is visible to the PostgreSQL backend.
b). the pljava.classpath *only* contains the full path to pljava.jar.

Kind regards,
Thomas Hallgren
