Hi,

Can you include the output of the following?

SELECT schemaname, jarname
  FROM sqlj.classpath_entry NATURAL JOIN sqlj.jar_repository
  ORDER BY schemaname, ordinal;

SHOW pljava.classpath;
SHOW search_path;

Very often, an issue like what you are reporting will have an explanation among those settings.

SELECT schemaname, jarname
  FROM sqlj.classpath_entry NATURAL JOIN sqlj.jar_repository
  ORDER BY schemaname, ordinal;

SHOW pljava.classpath;
SHOW search_path;

SELECT schemaname, jarname
FROM sqlj.classpath_entry NATURAL JOIN sqlj.jar_repository
ORDER BY schemaname, ordinal;
return:

schemaname jarname
public pgjar

SHOW pljava.classpath;
return:

ERROR: unrecognized configuration parameter "pljava.classpath"

SHOW search_path;
return:

search_path
public, "$user", public

Oops, sorry, I copied the show pljava.classpath from an older issue, before the variable name changed. It would be show pljava.module_path in recent versions.

But even that might be less important here than

SELECT sqlj.get_classpath('public');

It's all right, glad you helped!
return:

get_classpath
pgjar

This may show more:

\c
SET client_min_messages TO debug1;
CREATE OR REPLACE FUNCTION test_pljava(query TEXT) RETURNS TEXT AS 'com.kamin.pljava.Cases.executeSelect' LANGUAGE java;

Sometimes during create-time validation, another exception further down the stacktrace may end up looking like the method wasn't found.

If you don't see more useful output at the client, also take a look in the server log afterward.

Was there any resolution?
