Hi it's me again. This is still in regards to the Chapter 4 example of the BMP entity bean, from Sun's J2EE Developer's Guide.

As I mentioned in my other post on this topic, I found that I needed to run cloudscape's IJ tool so I could "delete from account;" before I re-ran my application.

I decided I'd modify the Account EJB so that it would not simply throw an uncaught expection. So here is the modified method:The try catch block at the end is inserted by me. This works great now.

But I had a good deal of trouble gettting Sun's app server to "Update and Redeploy". In short, it doesn't work, or I'm perhaps expecting too much of it. I needed to completely remove the EJB From the Account app, and re-do the EJB Jar Wizard, resetting all the jdbc stuff, and the transaction support, etc..

Is there no way for the app server to realize that a recompile is necessary, since the source class files have changed? It seems to do this check, but poorly. Example: here is the output in the DOS window when I undeploy the app, and click "update and redeploy"
But there is code generation required! How to get it to realize this is the problem.

see my response to your other post.

I eventually realized that 'update and redeploy' was broken, but there is a work-around. hopefully you are not like the 'unlucky' co-worker of mine.

Thanks, Mike,
I think i have same bad luck as your 'co-worker', every time I need to break every JAR and War, then close the depolytool, reopen it and refill Wizard that was missed after i close the tool. Now I am sick for the deploytool but i have to use it to finish my project, my group members have no problem to use it.
Thanks again.
Amy

Completely unrelated to your questiojn, but...

In case of an exception, the statement will not be closed. Try

Similarly, I don't know where your Connection is coming from but you should take care to close it in a finally clause. (I hope you're not grabbing a permanent connection for your bean -- that's what connection pools are for).
