Mine is a web application. I have created a Jar containing some custom code and a few 3rd party jars. I have copied the custom jar to WEB-INF/lib folder. The 3rd party jars inside my jar are not visible to the application during deployment/runtime? I have no idea how to make them visible. Please help.

Thanks.
