POOSGi bundle imports packages from non-bundle jars: create bundles for them?
text
Body
copied!<p>I am new to OSGi, and am using Equinox. I have done several searches and can find no answer to this. The discussion at <a href="https://stackoverflow.com/questions/1340483/osgi-handling-3rd-party-jars-required-by-a-bundle">OSGI - handling 3rd party JARs required by a bundle</a> helps somewhat, but does not fully answer my question.</p> <p>I have obtained a jar file, <code>rabbitmq-client.jar</code>, that is already packaged as an OSGi bundle (with Bundle-Name and other such properties in its MANIFEST.MF), that I would like to install as a bundle. This jar imports packages <code>org.apache.commons.io</code> and <code>org.apache.commons.io.input</code> from <code>commons-io-1.2.jar</code>. The RabbitMQ client 2.7.1 distribution also includes <code>commons-cli-1.1.jar</code>, so I presume that it is required as well.</p> <p>I examined the manifests of these commons jars and found that they do not appear to be packaged as bundles. That is, their manifests have none of the standard bundle properties.</p> <p>My specific question is: if I install <code>rabbitmq-client.jar</code> as a bundle, what is the proper way to get access to the packages that it needs to import from the commons jars? There are only three alternatives that I can think of, without rebuilding <code>rabbitmq-client.jar</code>.</p> <ol> <li>The packages from the commons jars are already included in the Equinox global classpath, and <code>rabbitmq-client.jar</code> will get them automatically from there.</li> <li>I must make another bundle with the two commons jars, export the needed packages, and install that bundle in Equinox.</li> <li>I must put these two commons jars in the global classpath when I start Equinox, and they will be available to <code>rabbitmq-client.jar</code> from there.</li> </ol> <p>I have read that one normally does not use the global classpath in an OSGi container. I am not clear on whether items from the global classpath are even available when building individual bundle classpaths. However, I note that <code>rabbitmq-client.jar</code> also imports other packages such as <code>javax.net</code>, which I presume come from the global classpath. Or is there some other bundle that exports them?</p> <p>Thanks for any assistance!</p>
