 Response to myself....

Looking into source code, I see how the example works.....

Then i comment out the log call, as I see the process stop & exit when it
submit a message to the logger.

I'll have to study further how it work.

bye

questionorg.postgresql.pljava.internal.ServerException

Hi everybody,

I'm start in testing using Win Xp Postgres and PLJava.

As my old postgres installation was outdated i make a fresh installation,
incudingt also PLJava using, postgres-8-2-int installer.

Al the installation work well, and I suppose also the test runs good.

Then I start to write my own littlte class, and i "lear" ho pass and receive
data from postgres to the java class.

I got problem when i use jdbc connection. I play with a simple insert
statement, and it seem to work 8 i had received a 1 row result from insert
statement, but I got also an exception, and the record isn't stored in his
table.

Where i'm wrong ??
