2 JSF/Richfaces versions in same app server

Question

在同一个weblogic应用程序服务器中，如果我们使用2个不同的JSF / Richfaces版本托管2个diff ui它会正常工作还是会有任何类加载器异常？

Answer 1

If you separate the 2 UI into different .ear/.war files there should be no problem as you can do something like this in your weblogic-application.xml to specify preferred packages:

<prefer-application-packages>
   <package-name>org.apache.*</package-name>
</prefer-application-packages>

You can also try using the weblogic.xml to force what classes get loaded like:

<container-descriptor>     
   <prefer-web-inf-classes>true</prefer-web-inf-classes>   
</container-descriptor>
