I (think) I've managed to get a compile now using Eclipse and jdk1.5_10.
Unfortunately when registering my java function calls using

set search_path=voting;

select sqlj.install_jar('file:///usr/local/manifest/vote.jar',
  'vote', false);
select sqlj.install_jar('file:///usr/share/java/log4j.jar',
  'log4j', false);
SELECT sqlj.set_classpath('voting', 'vote:log4j');

CREATE or replace FUNCTION vote(AccountID int8, CapitalID int8,
  EventID int8, CanCopy bool, CopyFromEventID int8)
  RETURNS varchar
  AS 'uk.co.manifest.postgres.vote.VoteCalc.vote(long, long, long,
boolean, long)'
  volatile LANGUAGE java;

I get the error:

java.lang.NoSuchMethodError: Method org.postgresql.pljava.internal.Portal._
fetch(JZI)I

on that first install_jar() call followed by "failed to create JVM" on
any subsequent calls :-/ I've not found an answer by googling. Can
anyone help?
