----------------------------------


Thanks for your quick response, your patch resolves our problem. I agree that this could best be characterized as a bug in Tomcat and it is great that you nevertheless provided this solution.

> Embedding Felix within a webapp that is deployed on a Tomcat gives the following problem:
> Felix is started and the ExtensionManager registers the URL "felix://extensions/" with the parent URLClassLoader, which is Tomcats WebappClassLoader. The org.apache.jasper.compiler.TldLocationsCache then fails to initialize because it tries open a connection to this URL (in the scanJars method). As a result, it is at least not possible to use JSPs.
> The partial stacktrace is shown below. The message "Resource not provided by any extension!" comes from the IOException that the ExtensionManager throws when it is requested to open the URL for "felix://extensions/".
> SEVERE: Servlet.service() for servlet ShowServlet threw exception
> org.apache.jasper.JasperException: Unable to initialize TldLocationsCache: Resource not provided by any extension!
>         at org.apache.jasper.compiler.TldLocationsCache.init(TldLocationsCache.java:254)
>         at org.apache.jasper.compiler.TldLocationsCache.getLocation(TldLocationsCache.java:225)
>         at org.apache.jasper.JspCompilationContext.getTldLocation(JspCompilationContext.java:527)
>         at org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:423)
