How to get a resource in another bank

Question

I have a jar built into a package that should receive a resource packaged with it like this:

MyBundle
  -\ src
  -\lib
    -\MyEmbeddedJar
      -\src
        -\SomeClass
      -\someResource.xml

I am trying to access "someResource.xml" from "SomeClass" as follows:

SomeClass.class.getResource( "someResource.xml" ); 

But I’m out of luck. I tried several options with added CWD (for example: ./ someResource.xml), but I just can't load this resource.

I know that the “right” way is to use Activator to return to the appropriate classloader, but the built-in jar can be used in other projects, so I would not want to add special OSGi code to it to make it play well with OSGi.

Is there any other way to load resources in OSGi agnostically from OSGi?

, SomeClass, java.net.URL. someResource.xml .

SomeClass :

new SomeClass( FileLocator.find( Activator.getDefault().getBundle(), new Path( "./someResource.xml" ), new HashMap< String, String >() ) );

. , SomeClass? , , ?

:

embedded.jar
    src/SomeClass.class
    someResource.xml

embedded.jar embedded.jar Bundle-Classpath.

SomeClass.class.getResource("someResource.xml") , src/someResource.xml, SomeClass src. someResource.xml , SomeClass.class.getResource("/someResource.xml") .

OSGi, , Java.
