run.client_71a task of Workbook (by Burke, et. al.)

[cchoi]

Hi,

This task creates an entity EJB with a specified primary key; therefore the corresponding record is inserted into the table.
When you run the task after you've run it once already, you get ...DuplicateKeyException...as expected.

But it seems the data is lost when JBoss is shutdown.
If you run the same task again after having restarted JBoss, you don't get ...DuplicateKeyException...;
i.e., the entity EJB is created with no problem as if it hadn't been created.

How come the data is lost when JBoss is shutdown?
How could I keep the data even when JBoss is shutdown?

Thank you very much for your explanations in advance:)

Are you sure the record is updated.

When you use cmp stuff and don't be carefull it will create the tables for you at start up. And so all data is lost.

Is the data lost when you shutdown or startup

Thank you very much, pvamstel. Problem resolved.
Like you said when JBoss re-starts it re-create table so the data originally in the table are re-set.
I set the value of <remove-table> element of
jbosscmp-jdbc.xml to false; then, now JBoss doesn't reset the table's data anymore when it re-starts.

Thank you again:)
