Hello,
in the application that I'm working on, there's an javax.servlet.Filter
class defined and mapped to a servlet (in the web.xml):
> <servlet>
> <servlet-name>MainServlet</servlet-name>
> <servlet-class>package.control.MainServlet</servlet-class>
> </servlet>
> <filter>
> <filter-name>MigrationFilter</filter-name>
> <filter-class>package.migration.MigrationFilter</filter-class >
> </filter>
> <filter-mapping>
> <filter-name>MigrationFilter</filter-name>
> <servlet-name>MainServlet</servlet-name>
> </filter-mapping>
The web.xml-file is located in Project/WebContent/WEB-INF/web.xml. I am
registering the whole WebContent-directory as a recource in the
plugin.xml (working with the JSPs in that directory (and subdirectoies)
works fine, so that recource-definition should work right).
At the moment I'm running it all with the jetty-bundle under eclipse.
How can I get that filter to work correctly?
Johannes

Hi Johannes,
The OSGi Http Service does not provide direct support for filters.
That said, if you can get over the method name, the HttpContext has a
"handleSecurity" method that can act in much the same way as a filter.
For the time being I'd suggest using this approach.

I've been experimenting with a FilterChainServletAdaptor
e.g.
FilterChainServletAdaptor chainServlet = new FilterChainServletAdaptor(new
MainServlet());
chainServlet.add(new MigrationFilter(), filterparams);
chainServlet.add(new AnotherMigrationFilter(), otherfilterparams);
....
httpService.registerServlet("/servlet", chainServlet, servletParams,
myHttpContext);
It looks pretty complex, but it actually works pretty well.
When I have a little more confidence in it I'll post it here --
