[Pljava-dev] PL/JAVA on Windows

Dear Thomas,

Definitely these lines of code are causing the
problem. Last day when I was working on getting pljava
installed I did not stop the server when making the
changes to the postgresql.conf file.

Later the evening when I rebooted my machine I got the
same error which I could not explain. So I completely
reinstalled postgresql and the problem was over.

Today I restarted the installation of pljava and there
it was again the strange error.

When I stop the server, change my postgresql.conf and
remove these lines of code, start the server, start
pgadminiii, I can access my database.

When I stop the server, put lines of code in the
postgresql.conf, start the server, it is no longer
possible to open the connection in pgadminiii.

With the error message mentioned.

After your reply I did shut down the server and added
the lines of code. Then I rebooted my machine, and did
the same test. It is giving me the same results.

So please help me out identifying what the problem is.

Regards,
Danny
