问题
I had an application which is tightly coupled with jacorb and it is working great with Jboss. Now, i have to migrate this application to deploy the same in Websphere 8.5.5. General flow is , my application will reach another system (developed in C++) through corba usign jacorb. since IBM is having its own ORB implementations, My application is getting deployed in websphere. If my application is modified to make use of IBM orb jars, then 80% of applciation have to change. Kindly suggest me the way to include jacord proeprties and jar to resolve the errors.
My trails : All trails are independent to each other.
1) Kept my orb.properties, jacorb.jar and removed IBM orb.properties in WAS->JAVA->JRE->lib
2) Included my files in JVM classpath through Admin console.(Server failed to start after this change).
3) Modified the IBM orb.properties with jacorb properties but getting classcast exceptions.
