We are loading a custom build jar files from shared-dir and corresponding property file from common/wsrr dir. Things works fine till we have only one broker instance on the server or we need to load the same jar/property file from all the brokers.
Now we need to have another instance of broker (V7.0.0.4) which needs to be load a sligtly updated version of jar and corrosponding property file.
Option that we could find, it to create the new broker with diffrent workpath and place our jar file and property file there. But this required the broker to be recreated, which we do not want to do.
Please advise if there is a better solution for above problme. |

It really depends on how one is doing this. Certainly one shouldn't copy them into the broker install, nor should one alter the system level CLASSPATH.
Yes, use a JavaClassLoader configurable service. It allows you to create separate class loaders for *each* Java Compute node, if you really want.
This means you don't have to have a new EG, or a new Broker to use two levels of some set of Jar files. You just need two JCNS. |
