Subject Re: Eclipse + Geronimo + EJB = NullPointerException?
Date Thu, 26 Oct 2006 12:15:09 GMT
There must be a tag like given in the web.xml if your EJB is locally 
referred one.

<!-- To refer local EJB's  -->
	<ejb-local-ref>
		<ejb-ref-name>ejb/BankManagerFacade</ejb-ref-name>
		<ejb-ref-type>Session</ejb-ref-type>
		<local-home>org.apache.geronimo.samples.bank.ejb.BankManagerFacadeHomeLocal</local-home>
		<local>org.apache.geronimo.samples.bank.ejb.BankManagerFacadeLocal</local>
		<ejb-link>BankManagerFacadeBean</ejb-link>
	</ejb-local-ref>

If still have problem please post your TigerUtil.java, ejb-jar.xml and 
openejb-jar.xml files.

Have a look at :
