Surely I'm doing something wrong but after reviewing everything a lot of times, watching all the videos I've been able to found about Libra on Youtube, trying to do the same from several different ways... a I always get a 404 error when a simple Hello World is invoked.

For instance, I've created a Dynamic Web Project (2.5) with OSGi facet support and added a Hello World servlet. Everything seems fine: the dual project configuration (as Dymanic web and plugin project), etc.

If I run the Dynamic Web Project on Tomcat, I'me able to read the Hello World servlet output.

However, as OSGi Bundle... despite the MANIFEST is present and properly configured, the plugin bundled created and deployed, even it is loaded into Equinox (it is shown as ACTIVE bundle from the Apache Equinox Gogo console by running the ss command) , the servlet is not found (404) on the Equinox Server!

I've also extracted the plugin content form the jar file and it looks right: the servlet class is present as well as the web.xml descriptor file properly configured with the servlet and the mapping and the expected webapp structure (WEB-INF, etc).

Maybe I'm invoking the servlet with a wrong path...


<protocol> is http.

I've edited the MANIFEST of the plugin bundle and it contains the same

Web-ContextPath: /<>

the <servlepath> corresponds to the <url-pattern> of the <servlet-mapping>

Just the same URL works with Tomcat.

Any suggestion?

PS: I've attached my project whether you want to look at it. It's quite basic.

The console output is shown below as it might help to track bundle versions. I would like to notice that I installed the latest stable Libra milestone ( available from the update site:

http ://

on my Eclipse Luna instance (4.4.1).

The Target Platform Profile is the Infocenter deployable feature built against Eclipse Luna. As the ServletBridge is not included in the Luna edition, I built it from the latest sources available on the repository, hence the version is 1.3.0. Despite it, I've downgrade the ServletBridge to the 1.0.2 version shipped with the Eclipse SDK 3.7.2 version getting the same results, so it looks like not having any impact.

Another noticeable thing is that the jasper version was downgraded to support 2.5 Servlet API (Indigo) rather than the default 3.0 version.

That said, everything above works fine.

The only one pending issue would be seeing the damn HelloWorld servlet Mad
