I test the Apache Felix Servlet Bridge with an example where Apache Felix
Karaf is launched but Tomcat generates this error during initialization of
the proxy bridge servlet
-->

How the ProxyServlet retrieves such bundleContext ?
Here is my config :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>

</servlet>
<servlet-mapping>
<servlet-name>proxy</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
WebAppListener class :

private Main main;
public void contextInitialized(ServletContextEvent sce) {
try {
LOG.info("contextInitialized");
String root = new File(sce.getServletContext().getRealPath("/")
+ "WEB-INF/karaf").getAbsolutePath();
LOG.info("Root: " + root);
System.setProperty("karaf.home", root);
System.setProperty("karaf.base", root);
System.setProperty("karaf.startLocalConsole", "false");
System.setProperty("karaf.startRemoteShell", "true");
main = Bootstrap.launch(new String[0]);
} catch (Exception e) {
main = null;
LOG.error( e );
}
}
public void contextDestroyed(ServletContextEvent sce) {
try {
LOG.info("contextDestroyed");
if (main != null) {
main.destroy(false);
}
} catch (Exception e) {
LOG.error( e );
}
}
}
