EJB3 lookup

Question

Hi,
We are working with JDeveloper Studio 10.1.3.1.0, and we are using EJB3 session beans. We can access our session beans using annotations, and this works fine, but we have a situation in wich we need access to a generic EJB (local interface), so we want to use the old lookup. But it doesn’t work, we get a javax.naming.NameNotFoundException, maybe we are using the wrong name?
This is an example of the EJB we are using:
@Stateless(name="MyProcessEJB")
public class MyProcessEJBBean implements MyProcessEJB {
And this is the code we are using to access the EJB, from another EJB:
Context context = new InitialContext();
Object process = context.lookup(name); // name is "MyProcessEJB"
Thanks in advance

Hi,
You could do one of the following:
1. Provide an orion-ejb-jar.xml in the META-INF directory (the same dir where ejb-jar.xml resides):
orion-ejb-jar.xml:
<?xml version = '1.0' encoding = 'windows-1251'?>
<orion-ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-ejb-jar-10_0.xsd" schema-major-version="10" schema-minor-version="0">
    <enterprise-beans>
        <session-deployment name="MyProcessEJB" local-location="SomeLookupName"/>
    </enterprise-beans>
    <assembly-descriptor>
    </assembly-descriptor>
</orion-ejb-jar>Then you can look it up via:
MyProcessEJBLocal bean = (MyProcessEJBLocal)ctx.lookup("SomeLookupName");
2. If you are accessing the EJB from a web module, you can define the following in web.xml:
<ejb-local-ref>
    <ejb-ref-name>SomeLookupName</ejb-ref-name>
    <ejb-ref-type>Session</ejb-ref-type>
    <local>some.package.path.MyProcessEJBLocal</local>
    <ejb-link>MyProcessEJB</ejb-link>
</ejb-local-ref>And then you can look it up by the name you specified in the &lt;ejb-ref-name> tag. In my example, it is: "SomeLookupName".
