DTD to set Entity Bean's JNDI Name?
My question is what deployment descriptor I use to bind a JNDI name to my Entity Beans.
I am stuck.
My applicartion deployes with no error messages. I have some Servlets included that all work.
AND ... deploying my application even creates all the required database tables correctly.
However, when I pass a Game object to a Servlets doPost () where I want the Servlet to create the GameBean, I cannot find my Bean Objects.
And when I look in the JNDI list in the console they are not there.
If anyone is willing to help, here are the sections of the code I think are relevant for one Bean:
<ejb-jar> <enterprise-beans> <!-- MemberBean --> <entity> <description>MemberBean Definition</description> <display-name>MemberBean</display-name> <small-icon/> <large-icon/> <ejb-name>MemberEJB</ejb-name> <local-home>org.projects.games.go.MemberLocalHome</local-home> <local>org.projects.games.go.MemberLocal</local> <ejb-class>org.projects.games.go.MemberBean</ejb-class> <persistence-type>Container</persistence-type> <prim-key-class>java.lang.Integer</prim-key-class> <reentrant>False</reentrant> <cmp-version>2.x</cmp-version> <abstract-schema-name>MemberSchema</abstract-schema-name> <cmp-field><field-name>id</field-name></cmp-field> .... other fields <primkey-field>id</primkey-field> <resource-ref> <description/> <res-ref-name>DefaultDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> <res-sharing-scope>Shareable</res-sharing-scope> </resource-ref> </entity> ... </enterprise-beans> </ejb-jar>
