JNDI access to J2EE components

[Shobhan Ganta]

Hi All,

This question is from HFSJ mock exam 11 Q.9

Which are DD elements that provide JNDI access to J2EE components?
(Choose all that apply.)
A. <ejb-ref>
B. <entity-ref>
C. <ejb-local-ref>
D. <session-ref>
E. <ejb-remote-ref>

The correct answer given is A, C (explanation : (servlet spec 9.11)-In addition, <ejb-local-ref> also provides the web app creator with a JNDI reference to J2EE components.)

but I feel the following code snippet will be used for declaring the JNDI access.

<env-entry>
<env-entry-name>rates/discountRate</env-entry-name>
<env-entry-type>java.lang.Integer</env-entry-type>
<env-entry-value>10</env-entry-value>
</env-entry>

I don't see any of these tags available in the question options. Can someone please explain?

Thanks
Shobhan

You are right env-entry also has to do with JNDI lookup, but according to the Servlet2.4 spec all of the following tags have to do with JNDI lookup:

SRV.13.1 Deployment Descriptor Elements
Syntax for looking up JNDI objects (env-entry, ejb-ref, ejb-local-ref, resource-ref, resource-env-ref)
