Hi All,

We are using WebLogic 8.2 server for our project. We have JMSs and MDBs. In Weblogic, each queue can be configured for Time To Deliver Override. See attachement for the Time To Deliver Override configuration. More details on this click the following link Using Time To Deliver Override, one can specify the schedule at which the queue should deliver the message to the MDB. Example: deliver message to MDB only from 9AM to 4PM.

Is there any similar feature available in JBOSS 5.1 GA?

I worked for a MNC. Notice period was 3 months. i.e. Either serve 3 months notice period or pay 3 months basic salary. I gave 2 weeks notice period. Manager accepted it and waived my balance notice period.

Step 1: send a resignation mail to your manager.
Step 2: your manager will call you for the discussion. Negotiate with him for the earliest release. Ask him one week(No harm in asking one week if company policy says 3 months. There is a chance for full waiver of your notice period. just try..!!)
My opinion: If resigned, one should not stay more than 2 weeks in the company.
Step 3: upload your resignation details in your company's separation system. (Must for HR people to track)

These 3 steps should happen in maximum 3 days.

==================SAMPLE LETTER=========================
Dear <manager>,

I hereby tender my resignation from my position as System engineer. I request you to relieve me on or before 26th April 2008. During this period I will handover the charges as required.

It has been a genuine pleasure working for company during these past 2.5 years. I would like to thank you for the opportunity to be a part of your team.

your's sincerely

All the best..!

Hi Rahul,

1. The Client Calls this method to tell the container that he(client) is done using the bean's EJB Object reference:

Here, Client is done with EJBObject reference not with entity. So if remove method is called, Entity in Database will be deleted. #1 is applicable for Session Bean, where if client is done, he/she can call remove method. it is not possible with Entity Bean. No method for doing so in Entity Bean. :-)
1. No methods for this kind of task

2. ejbRemove()

3. setEntityContext()

4. ejbActivate()

In home interface, in your case return type should be Collection not just String.


In Bean,

//Query for ejbSelectGetAllEmpNames SELECT OBJECT(m) FROM Employee m

//if Return EJBs Of Type is Remote
/*then at deploy time it says RemoteException Error processing ejb jar compilation failed*/
Should have remote interface for the Entity Bean. In your case, it should be Remote, because you are returning the Collection obtained from ejbselect method to a remote client

//if Return EJBs Of Type is None
If you give 'None' or 'Local', it will take it as 'Local'

Hope this reply helps you to resolve issues. If i am wrong please correct me.
