Web.xml version when moving to Jboss7

[davisonri_k12]

Currently i am working on migrating an application from Jboss 4.2.2 to jboss 7. in the older jboss version my web.xml looked like this

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

Notice the version is 2.4. when I deploy the application with this web.xml it seems to work well. But i have read in places that on jboss 7 the web.xml version should be 3.0 (since it is based on j2ee6)

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

      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_3_0.xsd"

      version="3.0">

I am not able to definitively figure out is original web.xml can be retained. Any one know if i need to change this ?

Hi,

you can still use legacy version of web.xml.

But you won't be able to use new features that servlet 3.0 spec brings.

but changing web.xml to be 3.0 complient should be simple change.

In short it is recomended so you can gain new functionalites but not required

Thanks. That makes sense. would you happen to know of any helpful documentation that illustrates the changes to the web.xml from 2.4 to 3.0. Or if i dont intend to use any new features of servlet 3.0, is it just a matter of chaging the version and schema location ?

JSR-000315 Java™ Servlet 3.0.

It contains a substantial change log from version 2.3 onward.
