I spent several days trying to figure this out and have finaly succeeded. I could not find any place that had all this information in one spot so here it is.
I was trying to create an entity bean that used an identity column in an MSSQL table for it's primary key. Here is what I finaly came up with. I have finally successfully inserted a row into a MSSQL database table using an entity bean whose primary key is bound to an identity column. The code has two entiy EJB's. Look for the PropsIdentiyEJB. The trick was to set the prim-key-class to java.lang.Object, the return type of the ejbCreate() method to Object, the findByPrimaryKey parmeter to Object, the unknown-pk-class to java.lang.Integer and add the field-name tag set to key. Here's the script I used to create the table. Look for the PropsIdentityEJB ejb. | CREATE TABLE [dbo].[PropsTableIdentity] ( | [key] [int] IDENTITY (1, 1) NOT NULL , | [value] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL | ) ON [PRIMARY] | GO | Jbosscmp-jdbc.xml | <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE jbosscmp-jdbc PUBLIC "-//JBoss//DTD JBOSSCMP-JDBC 4.0//EN" | "http://www.jboss.org/j2ee/dtd/jbosscmp-jdbc_4_0.dtd";> | <jbosscmp-jdbc> | <enterprise-beans> | <entity> | <ejb-name>PropsIdentityEJB</ejb-name> | <datasource>java:/webquotes</datasource> | <datasource-mapping>MS SQLSERVER</datasource-mapping> | <pk-constraint>false</pk-constraint> | <table-name>PropsTableIdentity</table-name> | <cmp-field> | <field-name>value</field-name> | <column-name>PropsTableIdentity.value</column-name> | </cmp-field> | <unknown-pk> | <unknown-pk-class>java.lang.Integer</unknown-pk-class> | <field-name>key</field-name> | <column-name>key</column-name> | <jdbc-type>INTEGER</jdbc-type> | <sql-type>INTEGER</sql-type> | <auto-increment/> | </unknown-pk> | <entity-command name="mssql-fetch-key"/> | </entity> | <entity> | <ejb-name>PropsTableEJB</ejb-name> | <datasource>java:/webquotes</datasource> | <datasource-mapping>MS SQLSERVER</datasource-mapping> | <table-name>PropsTest</table-name> | <cmp-field> | <field-name>keyid</field-name> | <column-name>PropsTest.keyid</column-name> | </cmp-field> | <cmp-field> | <field-name>value</field-name> | <column-name>PropsTest.value</column-name> | </cmp-field> | </entity> | </enterprise-beans> | </jbosscmp-jdbc> | ejb-jar.xml | <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN' 'http://java.sun.com/dtd/ejb-jar_2_0.dtd'> | <ejb-jar> | <enterprise-beans> | <session> | <ejb-name>HelloEJB</ejb-name> | <home>com.dynix.webquote.HelloHome</home> | <remote>com.dynix.webquote.Hello</remote> | <ejb-class>com.dynix.webquote.HelloBean</ejb-class> | <session-type>Stateless</session-type> | <transaction-type>Container</transaction-type> | </session> | <entity> | <description>test of entity</description> | <display-name>PropsIdentityEJB</display-name> | <ejb-name>PropsIdentityEJB</ejb-name> | <home>com.dynix.webquotes10.PropsIdentityHome</home> | <remote>com.dynix.webquotes10.PropsIdentity</remote> | <ejb-class>com.dynix.webquotes10.PropsIdentityBean</ejb-class> | <persistence-type>Container</persistence-type> | <prim-key-class>java.lang.Object</prim-key-class> | <reentrant>False</reentrant> | <cmp-version>2.x</cmp-version> | <abstract-schema-name>PropsIdentityEJB</abstract-schema-name> | <cmp-field> | <description>value type</description> | <field-name>value</field-name> | </cmp-field> | </entity> | <entity> | <description>PropsTableEJB description</description> | <display-name>PropsTableEJB</display-name> | <ejb-name>PropsTableEJB</ejb-name> | <home>com.dynix.webquotes10.PropsTableHome</home> | <remote>com.dynix.webquotes10.PropsTable</remote> | <ejb-class>com.dynix.webquotes10.PropsTableBean</ejb-class> | <persistence-type>Container</persistence-type> | <prim-key-class>java.lang.String</prim-key-class> | <reentrant>False</reentrant> | <cmp-version>2.x</cmp-version> | <abstract-schema-name>PropsTableEJB</abstract-schema-name> | <cmp-field> | <description>Keyid col</description> | <field-name>keyid</field-name> | </cmp-field> | <cmp-field> | <description>value col</description> | <field-name>value</field-name> | </cmp-field> | <primkey-field>keyid</primkey-field> | </entity> | </enterprise-beans> | </ejb-jar> | Remote file PropsIdentity.java | package com.dynix.webquotes10;
