getUrlsForBundlesWithTlds

public java.net.URL[] getUrlsForBundlesWithTlds(DeploymentManager deployer,
                                                BundleFileLocatorHelper locatorHelper)
                                         throws java.lang.Exception

The jasper TldScanner expects a URLClassloader to parse a jar for the /META-INF/*.tld it may contain. We place the bundles that we know contain such tag-libraries. Please note that it will work if and only if the bundle is a jar (!) Currently we just hardcode the bundle that contains the jstl implemenation. A workaround when the tld cannot be parsed with this method is to copy and paste it inside the WEB-INF of the webapplication where it is used. Support only 2 types of packaging for the bundle: - the bundle is a jar (recommended for runtime.) - the bundle is a folder and contain jars in the root and/or in the lib folder (nice for PDE developement situations) Unsupported: the bundle is a jar that embeds more jars.
