Hi Joe,

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

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"?>
<openejb>

        <Container id="cmp" ctype="CMP_ENTITY">
                ConnectorName db
                PoolSize 10
        </Container>

        <Container id="stateful" ctype="STATEFUL">
                Passivator   org.apache.openejb.core.stateful.SimplePassivater
                TimeOut 20
                PoolSize 50
                BulkPassivate  50
        </Container>

        <Container id="stateless" ctype="STATELESS">
                TimeOut 0
                PoolSize 10
                StrictPooling true
        </Container>

        <Container id="mdb" ctype="MESSAGE">
                ResourceAdapter mq
                ActivationSpecClass 
org.apache.activemq.ra.ActiveMQActivationSpec
                InstanceLimit 5
        </Container>

        <Connector id="db" type="DataSource">
                JdbcDriver   org.postgresql.Driver
                JdbcUrl      jdbc:postgresql://localhost/zhou
                UserName     joe
                Password     xianzheng
        </Connector>

        <Resource id="mq">
                BrokerXmlConfig broker:(tcp://localhost:61616)?useJmx=false

                ServerUrl vm://localhost?async=true
        </Resource>

        <Connector id="mq_connector">
   ResourceAdapter mq
        </Connector>
        
        <Deployments dir="apps/" />

</openejb>

I suspect it is caused by the db connector. How may I fix this please?
Thanks for your time in advance.

Regards,

Joe
