Java and JavaScript in the Database

I am trying to set up a db to be able to develop pl/sql using java stored procedures.

When attempting to use the loadjava utility, i get:

ora-29554 unhandled java out of memory condition

here is what i have:

ora 9.2.0.1.0 running on winXP Pro.
756 MB ram, with 1GB virtual memory set up.

shared pool: 80MB
buffer cache: 48MB
large pool: 48MB
java pool: 104MB

total sga: 280MB
sga max size: 1GB

java_max_sessionspace_size: 2048
java_soft_sessionspace_limit: 250

System tablespace: 700MB, used 487MB
undotbs1: 1.1GB, used: 19MB
undo mode: auto

from metalink, i am looking at notes 204935.1 and 120994.1, which has details on setting this up. i seem to have everything set per those docs, but i still get the error message when i try to use the loadjava tool, and/or when i try to create a java class directly in the db by using 'create or replace and compile java source named ...'

i know that java is enabled. when i do:

select * from v$option;

the results show java = true.

when i do:

select count(1) from dba_objects where object_type like '%JAVA%';

i get 10452 objects found.

so i'm not sure what to try next or why i am getting the out of memory error. can anyone help?
