[ZHAO,YUN (HP-China,ex2)]

My database.xml is like the following, and the datasource which i defined in the example server of weblogic is working fine! <database name="petstore" engine="oracle">     <jndi name="datasource-petstorePool"/>     <mapping href="user.xml"/> </database> Is there other thing i need to declare in the database.xml file???   In the ejb-jar.xml file, i have the following transaction description for the session bean and when i use entity bean instead of JDO, the session bean works fine. <container-transaction>       <method>         <ejb-name>SignOnEJB</ejb-name>         <method-intf>Remote</method-intf>         <method-name>createUser</method-name>         <method-params>           <method-param>java.lang.String</method-param>           <method-param>java.lang.String</method-param>         </method-params>       </method>       <trans-attribute>Required</trans-attribute>     </container-transaction>     <container-transaction>       <method>         <ejb-name>SignOnEJB</ejb-name>         <method-intf>Remote</method-intf>         <method-name>authenticate</method-name>         <method-params>           <method-param>java.lang.String</method-param>           <method-param>java.lang.String</method-param>         </method-params>       </method>       <trans-attribute>Required</trans-attribute>     </container-transaction> -----Original Message----- From: Andrew [mailto:[EMAIL PROTECTED]] Sent: Sunday, October 27, 2002 8:10 PM To: [EMAIL PROTECTED] Subject: Re: [castor-dev] how can i inform Castor JDO engine that i will use EJB Container's Transaction Management? 1)You need to configure castor for container integration- through JNDI DataSource in database mapping config file(see site for reference). 2)Be sure that you set up properly container configuration(transaction management) in EJB descriptor.   Regards.     ----- Original Message ----- From: ZHAO,YUN (HP-China,ex2) To: [EMAIL PROTECTED] Sent: Sunday, October 27, 2002 12:52 PM Subject: [castor-dev] how can i inform Castor JDO engine that i will use EJB Container's Transaction Management? I have a session bean and a jdo class.   The session bean's business methods use Weblogic Server's EJB Container's Transaction Management--there are no  "db.begin()" and "db.commit()" calls again,  and create and use a org.exolab.castor.jdo.Database object, too.   But it seems that JDO engine don't know that it is using Container Management Transaction[CMT], because it threw a exception with a message of "there is no transaction in the executed thread".   So i want to know how i can inform Castor JDO engine that i will use EJB Container's Transaction Management?   Thank you very much!     yamssar
