[Pljava-dev] PLJAVA - could not load library libpljava ...

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.

Thomas Hallgren
