The Buttso Blathers: weblogic.xml and prefer-application-packages

11 August 2011

weblogic.xml and prefer-application-packages

Short and sweet this one, purely for my own future simple reference.

To use prefer-application-packages in weblogic.xml, it looks like this:

<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.2/weblogic-web-app.xsd">

  <jsp-descriptor>
    <keepgenerated>true</keepgenerated>
    <debug>true</debug>
  </jsp-descriptor>

  <context-root>/quicktest</context-root>
  
  <container-descriptor>
    <prefer-application-packages>
        <package-name>org.codehaus.jackson.*</package-name>
        <package-name>org.codehaus.jettison.*</package-name>
        <package-name>org.objectweb.asm.*</package-name>
    </prefer-application-packages>
  </container-descriptor>

</weblogic-web-app>

Yes it is -- we added it specifically to support war level filtering since it's a common deployment model.

It's in the XSD, so must be a doc oversight.

I'll log a doc bug, thanks for pointing it out.

The WLS 10.3.6 documentation shows it as well now:

I had something on this topic a while back, have a look at this:

That seems like it covers what you are looking for.

Have a look anyway and post back if you still are having trouble.; 10:18 pm
