Hello
If you need only static resources, maybe you should simply register
Whiteboard-based resources? Something like this:
register a context to "get" a context path:
Dictionary<String, Object> properties = new Hashtable<>();
properties.put("osgi.http.whiteboard.context.name", "my-context");
properties.put("osgi.http.whiteboard.context.path", "/sample");
ServiceRegistration<ServletContextHelper> reg =
context.registerService(ServletContextHelper.class, new
ServletContextHelper() {}, properties);
register resources into this context path:
Dictionary<String, Object> properties = new Hashtable<>();
properties.put(HttpWhiteboardConstants.HTTP_WHITEBOARD_RESOURCE_PATTERN,
new String[] { "/static/*" });
properties.put(HttpWhiteboardConstants.HTTP_WHITEBOARD_RESOURCE_PREFIX,
"/resources");
properties.put(HttpWhiteboardConstants.HTTP_WHITEBOARD_CONTEXT_SELECT,
String.format("(%s=my-context)",
HttpWhiteboardConstants.HTTP_WHITEBOARD_CONTEXT_NAME));
ServiceRegistration<Object> resReg = context.registerService(Object.class,
new Object(), properties);
Then you'll be able to get resources from bundle's "/resources" directory
using URI's like "/sample/static/*"
But sure - your WAR approach should work too.
