I got the following error when I tried to deploy ejb:
19:46:13,320 ERROR [MainDeployer] could not create deployment: njar:file:/export/home2/jboss-3.0.0_tomcat-4.0.3/server/default/tmp/deploy/server/default/deploy/order.ear/123.order.ear^/order.jar

My ejb-jar.xml looks like this:

ejb-jar>
<display-name>Order Bean</display-name>
<enterprise-beans>

Order Bean
<ejb-name>OrderBean</ejb-name>
org.jboss.order.interfaces.OrderHome
org.jboss.order.interfaces.Order
<ejb-class>org.jboss.order.ejb.OrderBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<ejb-ref>
Order bean
<ejb-ref-name>ejb/OrderHome</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
org.jboss.order.interfaces.OrderHome
org.jboss.order.interfaces.Order
</ejb-ref>

</enterprise-beans>
</ejb-jar>

And my jboss.xml looks like this:

<?xml version="1.0"?>

<enterprise-beans>


<ejb-name>OrderBean</ejb-name>
<jndi-name>ejb/OrderHome</jndi-name>
<ejb-ref>
<ejb-ref-name>ejb/OrderHome</ejb-ref-name>
<jndi-name>jnp://gryphon:1099/ejbs/OrderBean</jndi-name>
</ejb-ref>

</enterprise-beans>


What could go wrong here?

Thanks,
