Thanks for the reply I will try this. I was under the assumption that the App server was supposed to create the finder methods?

I have created a simple Bean Managed Persistence EJB and got it to work with PointBase4 and JBoss3.0.3
I am now try to convert the bean to use Container mananged persistence but I am having problems running the test program.
The EJB is a simple "Quote of the day" app that reads a quote from the database.
The table is defined as follows in Pointbase
**************************************************
CREATE TABLE "QOTD"."QOTD" (
"ID" INTEGER IDENTITY NOT NULL,
"CREATE_DATE" TIMESTAMP,
"MODIFY_DATE" TIMESTAMP,
"QUOTE_TEXT" VARCHAR(1000),
"DISPLAY_FLAG" BOOLEAN );
**************************************************
The Entity bean is defined in ejb-jar.xml as follows..
**************************************************
<ejb-jar>

<enterprise-beans>
...
<entity>
<ejb-name>quotecmp</ejb-name>
<home>qotd.QuoteCMPHome</home>
<remote>qotd.QuoteCMP</remote>
<ejb-class>qotd.QuoteCMPBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>qotd.QuotePK</prim-key-class>
<reentrant>false</reentrant>

<cmp-version>2.x</cmp-version>
<abstract-schema-name>QuoteCMPBean</abstract-schema-name>
<cmp-field><field-name>quote</field-name></cmp-field>
<cmp-field><field-name>display</field-name></cmp-field>
<cmp-field><field-name>lastMod</field-name></cmp-field>
<cmp-field><field-name>created</field-name></cmp-field>
</entity>
</enterprise-beans>
...
</ejb-jar>
**************************************************
The content of the jbosscmp-jdbc.xml packaged in the jar is :

**************************************************

**************************************************
I pieced this file together from various snippets of info on the net so not sure if it is correct!

When I run a simple test to create a new bean I get the following error:
**************************************************
javax.ejb.FinderException: Find failed: java.sql.SQLException: Expected to find "FROM" instead found
"QOTD" at position 13.

TIA for your help!
