ExtensionManager does not work with Tomcat
------------------------------------------
Key: FELIX-414
URL: https://issues.apache.org/jira/browse/FELIX-414
Project: Felix
Issue Type: Bug
Components: Framework
Environment: Felix framework 1.0.1
Tomcat 5.5.23
Reporter: Martijn Hendriks
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!
