Timeouts for RMI-Calls to EJBs
------------------------------

                 Key: EJBTHREE-1930
                 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1930
             Project: EJB 3.0
          Issue Type: Feature Request
          Components: ejb3
         Environment: Linux, SUN-Java5-20, JBoss 4.0.2, JBoss 4.2.3.GA
            Reporter: Bernd Köcke
         Attachments: tif-1.1.zip

I would like to introduce client defined timeouts for RMI-Calls to EJBs. We have EJBs which are called from webfrontends and background processes. The Frontends have strong timing demands, e.g they only want to wait 50ms to get an answer but they accept to goon without it. This can be solved by application desing, but we have running applications which should not change. By looking into the code I found that it should be enough to set the SO-Timeout on the clients socket and the goal was to do this without changes in the clients code and the EJBs. So I build a small framework that the client only needs a jar- and a property-file to set timeouts for the RMI-Calls. I build this for EJB 2.1 on JBossAS 4.0.2 and EJB 2.1 + 3 for 4.2.3.GA. I talked to Carlo and he said that the latter could be interesting. It is installed on the server side by additonal JARs and configuration, no patches to existing JBoss code is needed.

The attachment is a complete Maven Eclipse project with sources, classes and artifacts. The framework is called "Timed Invoker Framework" (TIF). I added JBoss deployment descriptor fragments to the ZIP and a readme PDF. The PDF is a copy of my internal Wiki page which describes usage and installation of TIF and the source contains JavaDoc.
