I have created an entity bean with a method getMember. My session bean has this code - for which I am receiveing a javax.naming.NameNotFoundException: Missing Node - Member. How do I write this lookup???
public java.lang.String getMember(Integer memberid)
{
String strMemberName = null;
try {
Context ctx = new InitialContext();
// Object obj = ctx.lookup("java:comp/env/ejb/member");
Object obj = ctx.lookup("java:comp/env/Member");
MemberHome aMemberHome = (MemberHome)PortableRemoteObject.narrow(obj,MemberHome.class);
Member aMember = aMemberHome.findByPrimaryKey(memberid);
strMemberName = aMember.getFname();
return strMemberName;
} catch (ClassCastException cce) {
cce.printStackTrace();
return "ClassCastException " + cce.getMessage();
} catch (NamingException ne) {
ne.printStackTrace();
return "NamingException " + ne.getMessage();
} catch (FinderException fe) {
fe.printStackTrace();
return "FinderException " + fe.getMessage();
}
}

I think your code is ok.
Do you get any exceptions at deploy time?
Have you specified a reference to the entity ejb in ejb-jar.xml (for the session ejb)?

hi
I think that it is 99% due to EJB, which is not deployed on the server.
check it out once again

Found standard partition.

I looked at the ejb-jar.xml and there is no reference to the entity in the session. There is a reference to the entity in the enterprise-bean. What tags am I susposed to use for the session bean to represent the entity???

This is a piece of ejb-jar.xml of a project i'm working on.
My session HousesInfo looks up for my PartyHouse bean, so i need a ref to it in:
-> ejb-jar.xml

-> jboss.xml (or your server file conf. file)

I'm refering the local interface of PartyHouseBean.

Hi,
You need to define a ejb reference for your local bean in your ejb-jar.xml in order for you to use java:comp/env
e.g.

Cheers.
