You can read some articles about bytecode processing and threads etc. here.

I am using websphere application server version with RAD But I cannot generate EJB stubs because of an error message which says "Cannot find RMIC because it is not installed. Expected location of RMIC is C:\Program Files\IBM\SDP70_1New\runtimes\base_v61\java\bin.

However RMIC is available in that location.
Some search in the google told me that the java used in eclipse may not be the one provided by websphere.
But I think the rmic is located inside websphere profile only.

Please help.

I just passed SCBCD 5.0 with 86%. I did not think I could do it without Head First .
I just read EJB3.0 from O' Reilly and the spec. I would say EJB specs are so beautifully written, its just like a book. But, I would say, if there was a 'Head First' available, my girl friend would have been happier .
Thanks a lot to the ranchers for support.

You should not narrow the object returned from the JNDI lookup unless you have a remote interface.

More seriously, you must have the ejb-jar.xml file in your EAR. It is mandatory to have this deployment descriptor for the EJB.

I thought ejb-jar.xml is optional in EJB3.0 spec. However even using an ejb-jar.xml did not work.

what exactly do i write in my ejb-jar.xml when i already have all the information in annotations
Yes, its part of the same application.. that is the ejb and the web application are in the same ear file
Thanks! but it still does not work

Here is the EJB

Here is the Local interface

And here is the servlet

now i have used the following request parameters.. but none of them works



i am not having any ejb-jar.xml

Hi, i'm absolutely new to ejb, so this is a silly question. I can access the EJBs from web container using @EJB annotation. But, when i try to use JNDI, the server log shows that the JNDI name does not exist. I'm using glassfish. Can somebody tell me how the default jndi names are used in glassfish, and how i can modify and assign custom jndi names?
Can anybody tell me if there is a way to use declarative authorization in j2ee in combination with JAAS authentication? I need this for my project.

why don't you check your history in the sun cert database and see if the kit is created, sent or not. if they are, probably they reached a wrong would need to request sun to resend it. otherwise mail sun telling them the problem.
