We use Java Proxy for some of our web front end to Gen server back end CICS/DB2 applications.
We have just recently upgraded the encyclopedia and GUI client-server environment from 8.0 to 8.5 IE1 (working on IR2).
I have a question concerning the Java proxy. We have a web app (Websphere, WAS 7) that is comprised of 20-30 proxy interfaces in the
web front end.
Currently they are all 8.0 proxies, but we are introducing one new proxy and making a change to another. These will be the first 8.5
proxies to be delivered/deployed.
Is it possible to deploy multiple common runtime jar files/collections to the same web app server?
Effectively we want both 8.0 and 8.5 common runtime jar to be in the classpath so depending on which version is called, it will be found.
i.e. we would deploy both the 8.0 common runtime jar (we call it agen80.jar) and the 8.5 common runtime jar (agen85.jar).
In very limited testing it seems that this would work OK, but it has not yet been tested with WAS or with My Eclipse Blue (our Java developer SDK)
Does anyone know this has been tried before? or accomplished?
Are there any issues or gotchas to this approach?
Does it even make sense?
