Rose,
First of all, the LD_LIBRARY_PATH is not applicable in a Windows 
environment. Windows use the PATH environment to find both executables 
and executable extensions (a.k.a. shared libraries or dll's). So, your 
problem is either the dynamic_library_path setting in the 
postgresql.conf or the PATH setting. LD_LIBRARY_PATH can be skipped 
altogether.

Placing the libpljava.dll in the root catalog seems to be a very bad 
choice and it doesn't solve any problem. Let libpljava.dll remain in the 
pl/java installation directory and set the dynamic_library_path to point 
to that directory.

The PATH environment that appoints the Sun Java dll's must be in effect 
for the PostgreSQL *server*. Setting it before you execute a *client* 
program (such as the deployer) will not help one bit. If you run the 
PostgreSQL as a service, the setting must be a system setting and the 
service must be restarted if you change it.

The PATH entries relevant to PL/Java are, assuming that your JAVA_HOME 
appoints the JRE (as opposed to jdk):

%JAVA_HOME%\bin\client;%JAVA_HOME%\bin

skip everything else under %JAVA_HOME%. It's irrelevant.

Regards,
Thomas Hallgren
