Hello, in the last days I tried to build a Java App that embedds Felix and gets build by Maven2. When starting the app outside eclipse in console, I got the error:
ERROR: Unable to start system bundle. (java.lang.NoClassDefFoundError: org.osgi.vendor.framework property not set) java.lang.NoClassDefFoundError: org.osgi.vendor.framework property not set ... I then found out that: on Site: http://static.springsource.org/osgi/docs/1.2.0-rc1/reference/html/spring-osgi-faq.html#incomplete-osgi-jar -> When doing integration testing I receive java.lang.NoClassDefFoundError: org.osgi.vendor.framework property not set... Remove the official OSGi jars (osgi.jar or osgi-r4-core.jar) from the classpath and use only the actual OSGi platform (Equinox/Knopflerfish/Felix) jars. The former provides only the public classes without an actual implementation and thus cannot be used during runtime, only during the compilation stage. Then Karls advice helped me very much. I learned that when ever you want to embedd felix, just look at org.apache.felix.main Project, its the best sample to start Felix embedded, because main is the starter for framework. Meanwhile I found a solution: 1. take org.apache.felix.framework as maven dependency 2. Embedd felix jar using maven-bunde-plugin ( <Embed-Dependency>*;artifactId=org.apache.felix.framework;inline=true</Embed-Dependency> in instructions Tag ) 3. to minimize Framework dependencies the Felix Starting-class one should use Packages like: org.osgi.framework.BundleActivator org.osgi.framework.launch.Framework org.osgi.framework.launch.FrameworkFactory and not Felix' special Packages Then the Felix embedded tutorial does work proper with maven2. I just wanted to tell, because before it took some days for me getting felix and osgi to work with maven. Perhaps someone will save time now. regards Matthias 2010/5/14 Karl Pauls <[email protected]> > > Just have a look at our main launcher (trunk/main).
