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

Violeta,

could you share more information on how tomcat is OSGi-fied ?
Are there perhaps BND files that can be used for this ?
What would be the easiest path for one to upgrade Tomcat ?
I'm OK with cloning virgo git repos if needed and building it if needed.

Thank you.

Jan

Is there an eclipse.org run Continuous Integration system to produce ORBIT artifacts automatically on a new release of the base open source project.

So every release of the upstream project gets an ORBIT release ?

We are using bundlor. You can easily create your own template.mf files.

As I said before:

The easiest path to upgrade Tomcat is to ask Gemini Web project to provide new version.
I'm expecting new Gemini Web release once Apache Tomcat 7 with JSR-356 implementation is released.

There is a strict policy for working with third party dependencies. [1]

Thanks for the document reference.

However it is not completely clear what point is being made by citing it.

The 3rd party open-source project has already been approved for tracking with ORBIT.
So presumably every release of that 3rd party project could have an ORBIT release without any significant red-tape.

Which then leads into the use of CI and automated systems to provide that. Now users who want newer versions of ORBIT artifacts do not need to spend their time and effort on independently building it themselves; only for that effort to be duplicated when eclipse.org makes an official release, they can instead spend that time improving and contributing the Eclipse product that relies on it.

I understand right now that a Virgo release is made for a specific version of a tomcat, instead of making an installer that will offer, go and download and combine and then unit test the Virgo parts with the Tomcat parts by using any compatible ORBIT tomcat version.

Nope
If we want to use Apache Tomcat version 7.0.35 for example we need to follow the process.
If we want to use Apache Tomcat version 7.0.42 again we need to follow the process.
etc.

I will again quote myself

Several time we needed to adjust our implementation to the newer version of Apache Tomcat.
One example [1]

Hi Violeta!

Will Gemini Web upgrade tomcat only when JSR 356 was implemented?

There some important bugfixes on Websockets made before 7.0.35

https://issues.apache.org/bugzilla/show_bug.cgi?id=55267
https://issues.apache.org/bugzilla/show_bug.cgi?id=55524

(this last is on trunk yet)

Hi,

I've just started a new mail thread for 7.0.44 voting. [1]
I expect to have a result this week.
So if it passes the vote we can update the Apache Tomcat in the Gemini Web.
