A simple CMP EJB, can not found EJB by lookup method, what's

[xieby2001]

There 4 EJBs

entity beans

studentBean:
ejb-name="student"
jndi-name="ejb/school/student"
local-jndi-name="ejb/school/studentLocal"

contactBean:
ejb-name="contact"
jndi-name="ejb/school/contact"
local-jndi-name="ejb/school/contactLocal"

courseBean:
ejb-name="course"
jndi-name="ejb/school/course"
local-jndi-name="ejb/school/courseLocal"

specialtyBean:
ejb-name="specialty"
jndi-name="ejb/school/specialty"
local-jndi-name="ejb/school/specialtyBeanLocal"

session bean
xstudioBean:
Client through xstudioBean to access the entity bean.

relationship between them:
(student:contact)-(1:1)
(student:course)-(m:n)
(student:specialty)-(n:1)

My code can be compiled and deploied. But when I wrote a client to access the entity bean, an exception occured, it seems like xstudioBean can not lookup then entity bean. This is my Jndi-name in xstudioBean:

private final static String JNDI_NAME_STUDENT = "java:comp/env/ejb/school/student";
private final static String JNDI_NAME_CONTACT = "java:comp/env/ejb/school/contact";
private final static String JNDI_NAME_COURSE = "java:comp/env/ejb/school/course";
private final static String JNDI_NAME_SPECIALTY = "java:comp/env/ejb/school/specialty";

my lookup method in xstudioBean:

private studentLocalHome lookupStudent()
throws NamingException
{
Context initial = new InitialContext();
Object objref = initial.lookup(JNDI_NAME_STUDENT);
return (studentLocalHome)objref;
}


I use xdocelet to generate deployment descripte file.

java:comp/env is for use inside individual beans
and must be configured using <ejb-ref>

You cannot use it from a client,
unless it is an "application client" which jboss
doesn't support. (optional part of the j2ee spec)

I have ejb-ref in my code like this:

@ejb:ejb-ref
view-type="local"
ejb-name="student"


my source code:

I know the problem, my jndi-name is not right, it should like this:

private final static String JNDI_NAME_STUDENT = "ejb/school/studentLocal";
private final static String JNDI_NAME_CONTACT = "ejb/school/contactLocal";
private final static String JNDI_NAME_COURSE = "ejb/school/courseLocal";
private final static String JNDI_NAME_SPECIALTY = "ejb/school/specialtyLocal";

Now, it can work fine.
