Many Apache projects (like commons.a.o) now include the OSGi metadata in their standard jars, so you can just load them as bundles. I don't know if that's the case for iText, searching "itext osgi bundle" on google should help find out if such bundles are available. Install the bundle (using OSGi console is the easiest for a quick test) , and check the OSGi console to see if it exports the packages that you need. If you cannot find an iText bundle, you could "OSGify" an existing iText jar using the bnd tool or the maven-bundle-plugin to add the required MANIFEST.MF information to it. Last (and least optimal) solution is to embed the iText classes in your bundle using the Embed-Dependency option of the maven-bundle-plugin, see http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html That last option might be the easiest for a quick test, the problem is that it adds bloat to your bundle and if another bundle needs those classes that would lead to duplication. Hope this helps, -Bertrand
