java - Cannot start embeded Apache Felix -

i want create java desktop application based on apache felix framework. created main java class:

when run jar file error:

can tell me how can solve problem?

you need have osgi framework on application classpath, e.g. felix. example should launch follows:

java -cp dx-57-1.0.jar;org.apache.felix.framework-4.2.1.jar test.main.startapplication
