Migration of DB2 java stored procedures to PostgreSQL

for a potential migration from DB2 on DB2/z to PostgreSQL I have to take care of a whole

somehow possible or is it anyway the same because Java = Java?

Any experiences/recommendations or helpful ressources?

There is PL/Java, but it is not part of the core PostgreSQL distribution, so you'd
have to build it yourself.

If performance is important or you don't want to depend on third-party modules,
post the code to PL/Python or PL/Perl. If the code is just glue around some SQL,
PL/pgSQL might be the best choice.

+1 for PL/Java, we've been using it for years.
