Jamal,

In the jaws.xml file below the <jaws> tag you should have lines like the following. This is so that it knows which datasource to use and which database mapping to use. http://www.jboss.org/documentation/HTML/ch05s02.html

        <datasource>OraclePool</datasource>
        <type-mapping>Oracle</type-mapping>

I presume in you jboss.jcml file you have added an entry for the OraclePool datasource http://www.jboss.org/documentation/HTML/ch03s05.html.

I also presume that if you look in your table that there is a row with a primary key value of "1" as ObjectNotFoundException is thrown when it cannot find the data in the database.

hope this helps,
Paul

Paul:

I was wondering if you can guide me on this one:

I am using JBoss-2.2.2_Tomcat-3.2.2 just downloaded today. Here is my
problem:

(I am running on window NT 4.0, jdk1.3, jdbc thin drivers classes12.zip from
Oracle)

I have constructed a simple CMP EJB called JDBCTEST. It represents a table
in an Oracle 8i with the same name. My table has two columns: ID, NAME .
The type for both columns is VARCHAR. The bean deploys without any problems,
but when I try to use the findByPrimaryKey() or create methods from a client
class this is the error I am getting:

Got context

Got reference

javax.ejb.ObjectNotFoundException: Object with primary key 1 not found in
storage

        at com.acs.ejb.JDBCTESTBeanClient.main(JDBCTESTBeanClient.java:56)

Here is my client class:

 <<JDBCTESTBeanClient.java>>

Here are is the EJB jar:

 <<JDBCTEST.jar>>

I am not 100 percent sure about the inclusion and use of jaws.xml file. It
does not seem to make any difference if it there or not. I would very much
appreciate your help in advance. I think I am not structuring my descriptor
files correctly.

Regards,
Jamal.
