I am a beginner on MyEclipse platform. I was very quickly able to make the first EJB program from http://www.laliluna.de/35.html thanks to the author. The XDoclet ran perfect and bean deployed on JBoss 4.0 in first go. Everything seems to go perfect but when it came to testing, a simple exmple to insert in database throws below mention error. Can anyone help me on this.

I am using MyEclipse 3.1M2, JBoss 4.0, MySql 4.1 and i have created entity bean for table Units (unitno – int, unitname-string, unitsym-string, description-string). From the error it looks like EJB engine failed to find units table. I am sure the table is there and its empty.
