我如何去使用一个OSGi包一个** ** CSS资源文件从另一个OSGi包

Question

我的项目目录结构（在Eclipse）：

MyProjectContainingCSS/ 
    src/  --> "source directory" on Eclipse's classpath/buildpath 
     com.me.myapp 
      style.css 


MyProjectInheritingCSS/ 
    src/  --> "source directory" on Eclipse's classpath/buildpath 
     com.me.myapp 
      StyleImpl.java 

我想在CSS文件中使用的style.css在类StyleImpl.java包含在OSGi包MyProjectContainingCSS在其他OSGi包MyProjectContainingCSS，

是这样的：

public class StyleImpl { 
    public static void main(String[] args) { 
     css = this.getClass().getResource("/com/me/myapp/style.css").toExternalForm(); 
     scene.getStylesheets().add(css); 
    } 
} 

我如何才能在另一个OSGi包的一个OSGi包中使用CSS资源文件？

谢谢大家提前。

UPDATE

的bnd.bnd文件

Bundle-Version: 0.0.0.${tstamp} 
-buildpath: \ 
    ../cnf/plugins/org.apache.felix.dependencymanager.annotation-3.2.0.jar;version=file,\

为了让您自己的捆绑文件，你可以这样做：

Bundle bundle = FrameworkUtil.getBundle(this.getClass()); 
Enumeration<URL> resources = bundle.getResources("/com/me/myapp/style.css"); 
if (resources != null) { 
    URL myCSS = resources.nextElement(); 
}    

如果你能找到其他的OSGi bundle对象，你可以这样做。我会尝试这样的：

Bundle bundle = FrameworkUtil.getBundle(this.getClass()); 
    Bundle[] bArray = bundle.getBundleContext().getBundles(); 
    Bundle cssBundle = null; 
    for (Bundle b : bArray){ 
     if(b.getSymbolicName().equals("com.me.myapp")) { 
      cssBundle = b; 
      break; 
     } 
    } 
    Enumeration<URL> resources = cssBundle.getResources("/com/me/myapp/style.css"); 
    if (resources != null) { 
     URL myCSS = resources.nextElement(); 
    }
