Hi,
I installed the bundle org.eclipse.equinox.http.jetty and all its
required bundles.
If I install a webapp bundle, it must use the
org.eclipse.equinox.http.registry's extension point to define where
resources or servlets can be found.
But why does the jetty bundle knows that a new webapp is installed and
how did it get the informations about that webapp?
How can I define the jsp's location in a webapp? Is that feature already
supported?
Thanks for help!!!
Best regards,
Sabine

sorry, can't help you with that one.

I do it as follows:

>
> Servlet adaptedJspServlet = new org.eclipse.equinox.jsp.jasper.ContextPathServletAdaptor(new org.eclipse.equinox.jsp.jasper.JspServlet(context.getBundle( ), "/WebContent"), "/jsp", "/WebContent");

Where "/WebContent" is the top-directory where all my web-recources are
located. Actually I've got another directory called "jsp" inside that
one, but it seems that all subdirectories are scanned for JSPs.
And "/jsp" is the name under which the JSPs are available. So for example:
<YourProject>/WebContent/Main.jsp
->
http://localhost/jsp/Main.jsp
and
<YourProject>/WebContent/jsp-files/Main.jsp
->
http://localhost/jsp/jsp-files/Main.jsp
On http://www.eclipse.org/equinox/server/jsp_support.php you can
download and import a team project set. I think you need that one to get
the bundles that support JSPs.
Near the end of that page there's also a project for JSTL-support.
Hope that helps,
Johannes

But I have a question:
Where does the "HttpContext" and "service" came from?

I think I forgot something. I wrote a class extending ServiceTracker
(Following a tutorial from the EclipseCon(?), I think - but I don't have
that one here anymore. I'll post where it can be found when I get it again).

And I use that class in the BundleActivator start()-Method:
> httpServiceTracker = new MainPluginTracker(context, "/jsp", "/WebContent");
> httpServiceTracker.open();
As you can see, I added the two variables "alias" and "dir", to use that
Tracker with different plugins.
Hope it is a bit clearer now. Sorry, I thought you could use the code I
posted yersterday in the Activator, but that don't seem to work.

1) org.eclipse.equinox.http.jetty exposes an OSGi Http Service.
2) org.eclipse.equinox.http.registry uses the extension registry to listens
for servlet and resource extensions and then will handle the registering in
all available Http Service instances.

JSPs (and taglibs) are found through the ServletContext.getResource methods
so it's a matter of setting up your resource paths correctly. The OSGi Http
Service creates a ServletContext from the getResource methods in the
HttpContext. In addition to servlets and resources there is another
extension point in org.eclipse.equinox.http.registry which specifically
deals with setting up an httpcontext which you might look at.
You can take a look at JSP support here
http://www.eclipse.org/equinox/server/jsp_support.php
There is no direct integration of this support in http.registry currently
however it's a planned item and will be added shortly.
