JBoss library conflit issue

ericox Dec 4, 2013 7:10 PM

I try to integrate jasper report into my current web application. The current web application config is as below:

As I can't upgrade the current web app's library, I can't integrate jasper report lib into the current library (commons-digester and common-beanutils can't support jasper report lib). Therefore, I need to add another web app for it. I used the the same structure of current web app and upgrade some libraries (commons-digester and common-beanutils). I tested in the following situation:

Case 1. deploy new web app only

Result => can generate report

Case 2. deploy both new and current web app

Result => After triggering report generation, it show the exception as below

java.lang.NoSuchFieldError: PRINTSCALING

Case 3. I try to use JBoss's isolated method adding jboss-app.xml into the ear file to isolate 2 web app.

It show the exception when deploying the new web app

Do brothers having any idea about the isolation problem and the jasper report generation exception?
