I am trying to deploy a cmp2 EJB using jboss 3.0.6 and jboss 3.2.0RC2. I am
using firebird jdbc/jca RC3. The table has three fields, int, VARCHAR(48),
VARCHAR(2), VARCHAR(48). I am using Eclipse 2.1.M5 and xDoclet 1.2RC2. I
keep getting the following error on deployment:

I have also tried stable versions of all the above mentioned products and
still get the same error.

I'm new to EBJ, JBoss and Firebird.

Sincerly,
Really feeling stupid in Illinois
