NameNotFoundException at context lookup
hi!
i want to use a stateless session bean in my servlet code, but i'm getting a namenotfoundexception when i try to do a lookup for my bean.
here's the code of the init()-method of the servlet.
public void init(ServletConfig config) throws ServletException {
try {
InitialContext ctx = new InitialContext();
aktenBean = (AktenBean)(ctx.lookup(AktenBean.class.getName()));
it = (aktenBean.getAllAkten().iterator());
} catch (Exception e) {
System.out.println("*******************");
System.out.println("** lookup failed **");
System.out.println("*******************");
e.printStackTrace ();
}
}
there's something wrong with call to ctx.lookup(...), but i don't know it.
the code of my bean:
@Stateless
public class AktenBean implements Akten {
@PersistenceContext (unitName="IngresManager")
private EntityManager em;
public Collection getAllAkten() {
return ((new AkteFacade(em)).getAllAkten());
}
}
the "IngresManager" is the name of the entitymanager in persistence.xml which is in the META-INF directory of the entities.par. the AkteFacade should use the entitymanager to make a query to my entity beans using the properties defined in the file persistence.properties from the directory jbosshome/deploy/ejb3.deployer/META-INF.
my application is packaged into an ear consisting of web.war (my web-app with the servlet), business.ejb3 (inside is stateless session bean) and entities.par (hibernate persistence archive with two entity beans).
the deployment is done well except the web.war. i got the following output on the jboss-console:

how can i use the stateless session bean in the servlet? i guess it's a trivial problem but i'm not able to solve it.
i appreciate any hint which will lead me to a right way. thanks in advance!
regards
patrik
ps.: my system config
eclipse 3.1rc4, jdk1.5update3, jboss4.0.3rc1 with ejb3, hibernate 3.1alpha
pps.: more info:
the global jndi namespace:
+- XAConnectionFactory (class: org.jboss.mq.SpyXAConnectionFactory)
+- containers (class: org.jnp.interfaces.NamingContext)
| +- ams.beans.stateless.AktenBean (class: org.jboss.ejb3.stateless.StatelessContainer)
(in the third line i see that the bean is bound, or am i wrong?)
