Modifying web.xml after enterprise application is already deployed

[Martin Lira]

Hi All,
I have an enterprise application (EAR file) that is deployed on a WAS 5.0. It consists of couple of web modules (WAR files). I made changes in some beans used in one of the web modules and added a new DataSource. Is there any way I can directly go and modify the web.xml for the web module and specify the resource references to the new DataSource directly rather than going through the process of redeploying?

Thanks,
Martin

Yes. The web.xml file is cached in the WebSphere config/cells/cell_name/applications/ear_name/deployements/app_name/war_name/WEB-INF directory. You have to make the changes in both places (the cache and the app) and then restart the application.

Honestly, you are better of just doing an update.

thanks for pointing that out William. But I found a work around. I am using the jndi name directly instead of the resource reference "java:comp/env/jdbc/ds". Is there any drawback of using this?

  
      myDataSource = (DataSource) new InitialContext().lookup(
 "java:comp/env/jdbc/ds");
      //Instead of this i do lookup directly on the jndi name
 
      myDataSource = (DataSource) new InitialContext().lookup(
         "jdbc/datasouce");
 
 

Thanks,
ML

Thanks for the hint...
