Is it possible to independently upgrade the version of Tomcat used by Virgo Tomcat? [message #869641]

Virgo Tomcat Server 3.0.3 ships with Tomcat 7.0.26, while Tomcat recently released version 7.0.27. Is it possible for me to "drop in" a newer version of Tomcat 7.0 into my Virgo Tomcat Server install, or is there coupling between Virgo and Tomcat which would prevent doing this (or make it a bad idea)?

If it is possible, is the process documented?

Thanks!

Theoretically you can.
In practice you should know that Tomcat does not ships OSGi metadata within the binaries.
So you should provide that by yourself.
As we have fragments attached to the catalina bundle, when you create the OSGi metadata you should keep the bundle symbolic names same as ours.

Thanks for the explanation.

Is the "OSGification" of Tomcat done manually, or are there scripts? If there are scripts, are they publicly available? Ideally I would use the same process that Virgo devs do (to prevent/avoid bugs, etc).

Sorry to dig up a slightly old thread.
I am evaluating Virgo Tomcat at the moment and I was wondering if someone is able to answer Jacobs question about the process the Virgo devs take to wrap Tomcat in OSGi bundles.
The reason I am asking this question is risk management. If there ever is a problem with the version of Tomcat Virgo ships with I would like to be able to upgrade Tomcat independently, following the same steps the Virgo developers take.

Hi,

We are using Eclipse Orbit project for our OSGIfication of the Apache Tomcat binaries - http://eclipse.org/orbit/.
You can use also Bundlor for this - http://www.eclipse.org/virgo/documentation/bundlor-documentation-1.1.1.RELEASE/docs/user-guide/htmlsingle/user-guide.html
However it is not just OSGIfication of the binaries. In Virgo Server for Apache Tomcat we have an internal integration with Apache Tomcat. Before moving to a new version of Apache Tomcat we execute a lot of tests in order to verify that everything is working property in OSGi environment.

Regards
Violeta
