Spring Web MVC does not work with OSGi

[dmitter]

Hi,

Not directly a Spring Web MVC related issue, but as there is no Spring OSGi forum yet that's the most relevant one.

I'm trying to get Spring Web MVC 2.5 RC1 running inside an OSGi container (equinox). However, Spring Web MVC does not get started. The state of my bundles after I start the OSGi container:

id      State       Bundle

Watch the bundles 19 (Spring Web MVC) and 16 (my own bundle that depends on Spring Web MVC). As you can see, the Spring Web MVC does not get started. The reason:

osgi> diag 19
initial@reference:file:2043365030.bundle/ [19]
  Missing imported package com.lowagie.text_0.0.0.
  Missing imported package com.lowagie.text.pdf_0.0.0.
  Missing imported package freemarker.cache_0.0.0.
  Missing imported package freemarker.core_0.0.0.
  Missing imported package freemarker.ext.jsp_0.0.0.
  [... and so on ...]

Fine. That tells me that I have to install these bundles. However, in the MANIFEST.MF of Spring Web MVC these packages are declared as "optional":

Import-Package: com.lowagie.text;resolution:=optional,com.lowagie.text
 .pdf;resolution:=optional, [... and so on ...]

Why can Spring Web MVC not get started without these optional dependencies? Did I overlook something?

Bye,

Daniel

Just realized that there is a Google group for Spring OSGi. So I'll repost it there... (see http://groups.google.com/group/spring-osgi/)
