Hi all,

I am building a web application that calls entity beans through a session bean. For example:

Code:

	try {
		  	a1 = home.create(new Date().getTime(), 1, leverancierID, productID, hoeveelheid);
	 	} catch (Exception e) {
			System.err.println("Kan order niet aanmaken: " + e);
			System.exit(2);
		}

I actually never get an error, everything compiles fine but nonetheless the data never gets inserted into the HSQL database tables. So, I thought something might be wrong with the descriptors. I checked and re-checked everything but the data does not get mapped to the database. It simply doesn't get inserted. It's a mystery.

Here are my descriptors (I actually have three beans but none insert data. Hereby I give an example for the bean called OrderBean)

And my web application server specific (I use JOnAS) descriptor

One last thing I'd like to mention: I based my code upon an example and all my fields in the DB table end with "_". If this is really a problem, why are there no errors then?

I really don't know what I should do. Could you guys please help me?
Thank you so much!
