Added patch equinox servlet bridge:
1) Filter support from http://angelozerr.wordpress.com/2010/09/08/osgi-equinox-in-a-servlet-container-step4/ 2) Modify to work with OSGi web container ( geminiweb ) instead of normal servlet container

* The java.net.URLClassLoader class allows one to load resources from arbitrary URLs and in particular is optimized to handle

|

|
* The CloseableURLClassLoader is meant to replace the URLClassLoader and provides an additional method to allow one to "close" any

|
* resources left open. In the current version the CloseableURLClassLoader will only ensure the closing of jar file resources. The
|
