hi... There is two case that i would like to hear opinion from you guys.I use EJB to pass all the data to different machine and location.I am using orion 1.4.8 for all the location. first case: one client sent data to destination named ormi://machineA/A and forward all the data to 3 different machine named ormi://machineB/B,ormi://machineC/C,ormi://machineD/D concurrently. Some thing happen went machineA try to forward all the data to this 3 machine concurrently. MachineA give exception java.lang.NullPointerException domain was null. seconds case: one client sent data to destination named ormi://machineA/A and forward all the data to 3 different machine named ormi://machineB/A,ormi://machineC/A,ormi://machineD/A concurrently. But only machineB get all the data for machineC and machineD. Therefore machineB get is 3 data. Suppose every machine will get its own data. I had change the port number and its still point to same machine that its see first and give all the data although it didn't give any exception went machineA try to find ejb application in different machine. Had anybody out there had same problem with me. I would to hear from u guys. __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
