pljava failed to install in x64 Windows 7 - Mailing list pgsql-novice

Path:
   %JAVA_HOME%\bin;%JAVA_HOME%\bin\server

Classpath:
   C:\Program Files (x86)\PostgreSQL\8.4\lib\deploy.jar;C:\Program Files (x86)\PostgreSQL\8.4\lib\pljava.jar;C:\Program Files (x86)\PostgreSQL\pgJDBC\postgresql-8.4-701.jdbc4.jar

I also modified the postgresql.conf by adding the following lines:
   custom_variable_classes = 'pljava'
   pljava.classpath='c:/Program Files (x86)/PostgreSQL/8.4/lib/pljava.jar'

When I run the install.sql to install pljava, I receive the following errors:

------------------------------ 

Is there any clue on how to fix this? My guess is that the pljava.dll is not a 64-bit version, either that, or pljava.dll is looking for some dependency DLL that should be in 32-bit instead of 64-bit. Thanks!
