如何从eclispe rcp中的捆绑包中加载文件

Question

I am loading a property file in the eclipse bundle but my code is using InternalPlatform from eclipse package which is not the best way to do that because it is restricted package from the eclipse . How do I load this file from the classpath.

public Properties getProperties(String resourceName){
            Bundle bundle = InternalPlatform.getDefault().getBundle("sample-bundle");
            try {
                return PropertyFactory.getProperties(new URL("platform:/plugin/" + bundle.getSymbolicName() + "/" + resourceName));
            } catch (Exception e) {
                logger.error("Unable to load aegis config {}", e.getMessage(), e);
                return null;
            }



private static Properties getProperties(URL url) throws IOException {   
    Properties properties = new Properties();
    logger.info("Loading Properties  from {}", url);
    properties.load(url.openStream());
    return properties;
}

The Platform class provides an official way to get the bundle for a plugin given its id:

Bundle bundle = Platform.getBundle("sample-bundle");

You can then use the FileLocator class to find a resource in the bundle:

IPath path = new Path("relative path of resource in bundle");

URL url = FileLocator.find(bundle, path, null);

Note: Platform is org.eclipse.core.runtime.Platform in the org.eclipse.core.runtime plugin. Path is org.eclipse.core.runtime.Path .
