Entity Bean, with DB2 can't create

warx_sg Mar 22, 2005 4:25 AM

Hi all,

i have a simple Entity Bean; which has a multiple primarykey composed by three strings.
When i call the create method passing a PrimaryKey object i get the error :

javax.ejb.CreateException: Error checking if entity exists:com.ibm.db2.jcc.b.SqlException: DB2 SQL error: SQLCODE: -302, SQLSTATE: 22001, SQLERRMC: null

If i have an entity bean with one primary key everything works fine.
I use JBuilderX to generate EntityBean, JBoss 3.2.7 and DB2 as database.
I suspec that there are some problem with DB2 database.
Any good suggestion ?
Cheers.

Stefano

Did you trace SQL statements ?

uncomment tracing in log4j.xml for cmp plugins

Hi,

i just recreated a project with JBuilder, create a Session Bean an Entity Bean with a primary key composed by thrre fields and changed the log4j properties to tace the sql statements under JBoss.
Well, everything works fine.
I don't know how but it works.
Probably JBuilder did some mistakes to create automatically EJB in my project.
Cheers.

This is a problem of IDE. You never know what IDE did behind. It is better to use XDoclets
