Help for configuring openejb
Hi,
I'm a new openejb user, or even a new starter of J2EE.
I'm currently trying to configure the openejb to but encountered unexpected
NullPointerException.
My configure file is as below:
<?xml version="1.0" encoding="UTF-8"?>
ConnectorName db
PoolSize 10
Passivator org.apache.openejb.core.stateful.SimplePassivater
TimeOut 20
PoolSize 50
BulkPassivate 50
TimeOut 0
PoolSize 10
StrictPooling true
ResourceAdapter mq
ActivationSpecClass org.apache.activemq.ra.ActiveMQActivationSpec
InstanceLimit 5
JdbcDriver org.postgresql.Driver
JdbcUrl jdbc:postgresql://localhost/zhou
UserName joe
Password xianzheng
BrokerXmlConfig broker:(tcp://localhost:61616)?useJmx=false
ServerUrl vm://localhost?async=true
ResourceAdapter mq
I suspect it is caused by the db connector. How may I fix this please?
Thanks for your time in advance.
Regards,
Joe

Hey David,
I've tried the latest build and fixed my config file easily.
Thanks a lot for this.
I'll bother you later if I find more issues. -> I'm sure I will:)
Thanks,
Joe

Hi Joe,
I used your config to make some improvements. Running it through a
few times I found a mix of places where we should have given better
error messages, a bug or two, and a few places where we needed to add
more configuration options.
Some details here:
http://issues.apache.org/jira/browse/OPENEJB-742
http://issues.apache.org/jira/browse/OPENEJB-743
http://issues.apache.org/jira/browse/OPENEJB-744
http://issues.apache.org/jira/browse/OPENEJB-745
The beta 2 should be out in about a week (give or take considering new
years is coming up).
Till then this is what you need to do to get your config running in
beta 1. Modify these three elements to look like this:
<Connector id="db" provider="Default JDBC Database">
<Resource id="mq" provider="Default JMS Resource Adapter">
<Connector id="mq_connector" provider="Default JMS Connection
Factory">
In beta 2 those will be declarable pretty close to how you had them
originally:
<Connector id="db" type="DataSource"> // same as you had
<Resource id="mq" type="ActiveMQResourceAdapter">
<Connector id="mq_connector"
type="javax.jms.ConnectionFactory">
This is where OPENEJB-743 comes in. In beta 2 you'd get a message
like this from your original <Resource id="mq"> declaration:
org.apache.openejb.OpenEJBException: Failed Configuring
Service(id=mq): Cannot determine a provider for
Resource(id=mq_connector, type=null, provider=null).
Possible valid configurations might be:
<Resource id="mq_connector" type="javax.sql.DataSource"/>
<Resource id="mq_connector" type="DataSource"/>
<Resource id="mq_connector" type="ActiveMQResourceAdapter"/>
<Resource id="mq_connector" type="javax.jms.ConnectionFactory"/>
<Resource id="mq_connector"
type="javax.jms.QueueConnectionFactory"/>
<Resource id="mq_connector"
type="javax.jms.TopicConnectionFactory"/>
<Resource id="mq_connector" type="QueueConnectionFactory"/>
<Resource id="mq_connector" type="TopicConnectionFactory"/>
<Resource id="mq_connector" type="javax.jms.Queue"/>
<Resource id="mq_connector" type="Queue"/>
<Resource id="mq_connector" type="javax.jms.Topic"/>
<Resource id="mq_connector" type="Topic"/>
<Resource id="mq_connector" type="org.omg.CORBA.ORB"/>
<Resource id="mq_connector" type="ORB"/>
<Resource id="mq_connector" type="javax.mail.Session"/>
(fyi, the <Resource> and <Connector> tags are synonyms)
I've made a pre beta-2 build for you that has the changes:
http://people.apache.org/~dblevins/openejb-607397/
It should be pretty bullet proof, but if you run into any issues at
all definitely let us know as we are happy to make improvements and
love the feedback.

It's been a while since 3.0-beta-1 was released and lots of changes
made into openejb (most notably improved ejb3.0 compliance) and we're
working on releasing 3.0-beta-2. I've just built it for you so you
could give a shot and make it even better (way before it gets
released).
http://people.apache.org/~jlaskowski/openejb-3.0.0-SNAPSHOT-bin.zip
Try it out yourself and let us know how it works.

Hi Joe,
The config looks ok at first glance. Can you send a full stack trace
of the NullPointerException?
