[Pljava-dev] Newbie question org.postgresql.pljava.internal.ServerException

[stefano bianchi]

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As my old postgres installation was outdated i make a fresh installation,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 ??
