Thanks a lot Violeta....
Adding the following code , It did the trick for embedded tomcat program...
List<File> filterdJarfiles = getAppJarFilesAlone(folderName);
WebResourceRoot resources = new StandardRoot(contextNew);
for(File jf:filterdJarfiles){
String st =
jf.getAbsolutePath().substring(0,jf.getAbsolutePath().lastIndexOf(File.separator));
resources.addPreResources(new DirResourceSet(resources,
"/WEB-INF/lib",
st, "/"));
}
contextNew.setResources(resources);
CustomLoader loader= new
CustomLoader(contextNew.getParentClassLoader(),contextNew);
contextNew.setLoader(loader);
But required to set the loader though..
Thanks a lot...
