Loading the classes from a jar that is dynamically uploaded through a servlet

[Komal]

I am uploading a jar dynamically through servlet and saving it in my WEB-INF/lib directory. I want to get all the classes annotated with my @annotation,

have used reflections code below without any luck.. the manifest of the jar is readable but the classes are not.. the set of classes is 0

List<ClassLoader> classLoadersList = new LinkedList<ClassLoader>();

classLoadersList.add(ClasspathHelper.contextClassLoader());

classLoadersList.add(ClasspathHelper.staticClassLoader());

ConfigurationBuilder builder = new ConfigurationBuilder().setScanners(new SubTypesScanner(false), new ResourcesScanner(),

new TypeAnnotationsScanner());

Set<URL> set = ClasspathHelper.forClassLoader(classLoadersList.toArray(new ClassLoader[0]));

FilterBuilder filterBuilder = new FilterBuilder().include(FilterBuilder.prefix(exportPackage));

Reflections reflections = new Reflections(builder.setUrls(set).filterInputsBy(filterBuilder));

Set<Class<? extends Object>> classSet = reflections.getTypesAnnotatedWith(MyAnnotation.class);

What changes to the configuration will help get the classes from the jar that is dynamically uploaded..

I have tried adding the URLClassLoader to the classLoadersList, but that too dosent seem to help.. 

Also kept the uploaded jar in a separate folder than WEB-INF/lib but the issue remains..

Any suggestions will be highly appreciated.
