Such jars need to be embedded in an OSGI bundle. The bundle that embeds the jar can than export the required packages . > I ask this because I would like to make use of Commons Math library in my > osgi bundle. The Apache Commons Math jar (at least version 3.1.1) is an OSGI bundle. So you can install it the same way as your own bundles and just use it. > I tried to export the lib folder containing the external jar, along with the > src files during the creation of the bundle but that did not seem to help. Embedding a Jar by using the maven bundle plugin works by (1) adding the dependency to the jar (2) adding the <Embed-Dependency> {artifact-id1}, {artifact-id2} <Embed-Dependency> to the configuration of the "maven-bundle-plugin" (3) exporting the packages of the embedded jar file that you want to have globally available in the OSGI environment (e.g. packages of classes you are using in interfaces of services your bundle provides). This is best done by using the <_exportcontents> {package1}; version={package1-version}, {package2}; version={package2-version} </_exportcontents> The "maven-bundle-plugin" will automatically include the jars in the bundle and set the bundle classpath accordingly. But as mentioned above for Apache Commons Math this will not be necessary as this module is already a valid bundle. > > So please let me know if it is possible, if so, how to go about doing it. > You might also be interested in [1] as it provides some information on how to build custom Stanbol configuration. best Rupert [1] http://stanbol.apache.org/docs/trunk/production-mode/ > cheers, > Amar > > ------------------------------------------------------------------------------- > This message was sent using EURECOM Webmail: http://webmail.eurecom.fr > -- | Rupert Westenthaler [email protected] | Bodenlehenstraße 11 ++43-699-11108907 | A-5500 Bischofshofen
