Hi there,
I use NetBeans 4.1EA and J2EE RI. I have no problem with creating CMP
Entity beans using Pointbase or MySQL database server but when I want to
deploy CMP Entity bean which is mapped to a PostgreSQL table,
JCodeGenerator of Application server catches an Exception.
Unfortunately, I could find only one message that it's sender have my
problem and there was no reasonable reply to that. the message is:
> Having a strange problem with Sun studio 4 update 1 talking to postgreSQL
> 7.3. (Redhat version)
>
> Using the latest Postgres JDBC driver (both latest stable and dev
> releases)- in Sun studio I'm having problems mapping my container manager

and here is some information about my databse and app:
1. the database name is habib and is in localhost.
2. the table is student and here is it's columns:
CREATE TABLE student
(
id int2 NOT NULL,
name varchar(10),
CONSTRAINT student_pkey PRIMARY KEY (id)
)
WITH OIDS;
ALTER TABLE student OWNER TO habib;
of course, I checked WITHOUT OIDS, but the problem remains.
3. here is public_Module1Ejb.dbschema :
