    Unexpected transaction retries

    jesper6tv Newbie

      Im using JBoss 3.2.5.
      I have a problem with a SLSB, where in some cases, a call to one of its method is performed twice, that is the transaction is apparently being retried, without any Exception being thrown. No deadlock is being reported.
      Is this a feature or a bug?
      Does JBoss transaction management retry a transaction in case of resource timeout, or to serialize transactions?

      Regards
      Jesper

          There is retry logic on application deadlock detection. The retry attempt is logged at debug level. See the org.jboss.ejb.plugins.TxInterceptorCMT code.

            Thanks for the quick answer. That explains my problems.

            Will it be possible in a later release of JBoss (4.0?) to assign different MAX_RETRIES on a per Bean basis?

              Create an RFE for that on sourceforge.

              You can disable retries by specifiying a org.jboss.ejb.plugins.TxRetryExceptionHandler implementation in the container configuration in either the jboss.xml or standardjboss.xml

              <jboss>
              ...
               <container-configurations>
              
               <container-configuration extends="Standard Stateless SessionBean">
               <container-name>Retry</container-name>
               <container-interceptors>
               <interceptor>org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor</interceptor>
               <interceptor>org.jboss.ejb.plugins.LogInterceptor</interceptor>
               <interceptor>org.jboss.ejb.plugins.SecurityInterceptor</interceptor>
               <!-- CMT -->
               <interceptor transaction="Container">org.jboss.ejb.plugins.TxInterceptorCMT
               <retry-handlers>
               <handler>org.jboss.test.retry.interfaces.RetryHandler</handler>
               </retry-handlers>
               </interceptor>
              ...
