RE: Transaction question

[Simon Evans]

i think you need transaction attribute 'RequiresNew' in B, and 'Requires' on
A.
then A has to catch B's remote exception.

ejb-jar.xml like:

       <container-transaction>
         <method>
          <description>Transaction-handling for the SmsManager</description>
          <ejb-name>nl.unwired.sgs.sms.SmsManager</ejb-name>
          <method-intf>Remote</method-intf>
          <method-name>A</method-name>
         </method>
         <trans-attribute>Required</trans-attribute>
       </container-transaction>
       <container-transaction>
         <method>
          <description>Transaction-handling for the SmsManager</description>
          <ejb-name>nl.unwired.sgs.sms.SmsManager</ejb-name>
          <method-intf>Remote</method-intf>
          <method-name>B</method-name>
         </method>
         <trans-attribute>RequiresNew</trans-attribute>
       </container-transaction>

code like:

A(){
        try{
                b();
        } catch(Exception ex){}
}

so B will execute in a new transaction and rollback when an exception is
thrown. A will finish wihtout throwing an exception and commit its own
transaction.
