According the servlet 3.0 spec, tldScanner classes are picked up during web-app load phase from the classPath using SPI mechanism. Normal sequence is to scan; - WEB-INF/lib - parent URL classPath However with the BundleClassLoader being the parent classLoader of Tomcat web-app classLoder, it fails to pick up TLD scanner references reside in plugins directory. That is why we have used a our own JarScanner >> It seems that this is relate to JarScanner. Can someone tell me >> what I have done wrong here? Or a way to fix this?

I manually set the TldCache and manually added the JasperInitializer to the StandardContext to get rid of the NPE I will try to answer the an answered questions in other thread.
