Jetty failure accessing JSP [message #135101]

Dear Sir,
I've succesfully run a bundle implementing a servlet that response to an
HttpServletRequest, using Equinox with Jetty in an Eclipse project.

My problem is that simply changing the response from my servelet, from:
"
resp.getWriter().println("<html><body>Hello from old-Servlet1 </body></html>");
"
to
"
resp.sendRedirect("index.jsp");
"

I get an error in the browser, like:
"
HTTP ERROR 404
Problem accessing /index.jsp. Reason:
ProxyServlet: /index.jsp
"

Where "index.jsp" is a very simple JSP that works OK on a different
configuration (i.e. Eclipse on Tomcat).
The problem seems related to the fact that the "index.jsp" is not
available in "some classpath" for the Jetty engine, but I have no idea
where this "classpath" information should be placed.
I've not found any structure like the "webapp" that I use for Tomcat, so I
have really no clue.

Can you give me some hint?

Thanks in advance.
Kind regards.
Maurizio

This should definitely work. Can you post a sample project to show what
you're doing
Can you access the index.jsp directly e.g. without the redirect?

Dear Simon,
The answer to your question is: no, I cannot even acces the index.jsp from
the browser.

The only thing that I can do from the browser is:
"http://localhost:8080/myservlet"
This works OK and I can make some HTML through the
resp.getWriter().println(..).

But, if I do:
"http://localhost:8080/index.jsp"
I get the same error that I mentioned in my initial email, and to be
honest with you I think that they should be the same thing then the
resp.sendRedirect("index.jsp").

This is why I thought it could be a problem of "some classpath missing"
for Jetty server.
Where do I specify to the Jetty server the root of my web-app?
Using Tomcat I have the "webapp" folder and everything is in it.
Using the Jetty bundle where I can find it, if this still makes sense?

I could also post my small project, but I don't see from this web-form any
possibility to adding some attachement. Is there any way?

Thanks in advance for any hint in resolving this issue.
Kind regards.
Maurizio

How are you registering your JSPs? (Are you using
org.eclipse.equinox.jsp.jasper.JspServlet)
Are you using the extension registry or registering your Servlet's directly
using the OSGi HttpService.

Hi Simon,
Thanks for your reply.

I'm registering the JSPs in my plugin.xml using:
"
<extension
point="org.eclipse.equinox.http.registry.servlets">
<servlet
alias="/index.jsp"
class="org.eclipse.equinox.jsp.jasper.registry.JSPFactory" />
</extension>
"
For this I've also installed two bundles:
org.eclipse.equinox.jsp.jasper_1.0.100.v20080427-0830, and
org.eclipse.equinox.jsp.jasper.registry_1.0.0.v20080427-0830

I think that the above means that "I'm using the extension registry and
NOT the OSGi HttpService". I presume that this is OK, is it?

I'm NOT using org.eclipse.equinox.jsp.jasper.JspServlet.
My servlet is defined like:
"
...
public class Servlet1 extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
....
resp.sendRedirect("/index.jsp");
}
"

That's all I need to do.
What should I do for getting my "index.jsp" visible from that context?

Note also that I've checked via
"getServletContext().getResource("/index.jsp")" and
"getServletContext().getResourcePaths("/")", and both of them return valid
info. The seconds indicate:
"
[/bin/, /index.jsp, /.classpath, /WEB-INF/, /build.properties,
/.settings/, /plugin.xml, /.project, /src/, /hello.jsp, /META-INF/]
"

This looks like that my "index.jsp" is a valid resource for the context.
Is it?

Thanks in advance for your help.
Kind regards.

You need a bit more bundles. They have dependencies which will need to
be satisfied.

Can you launch with "-console" and type "ss" in the console to see if
all bundles resolve correctly?

Dear Gunnar,
Invoking ss at the Equinox console indicates:

Dear Gunnar,
According to what I read in the "OSGi based JSP Support" from the Eclipse
site, the required bundle should be:

javax.servlet.jsp [branch v2_0])
org.apache.common.logging [v1_0_4])
org.apache.commons.el [branch v1_0])
org.apache.jasper [branch v5_5_17])

Finally I do have all of them in the ACTIVE state:

0 ACTIVE org.eclipse.osgi_3.5.0.v20090520
2 ACTIVE javax.servlet.jsp_2.0.0.v200806031607

40 ACTIVE org.eclipse.equinox.jsp.jasper.registry_1.0.0.v20080427-0830
47 ACTIVE examples.servlet_1.0.0.qualifier

Despite that, I still get the error message:

Where should I focus?

Thanks.

That looks good so suggests something fairly basic is going wrong. Probably
the fastest way to get help is to export your "examples" project and attach
it so someone can take a look.

Here's the trimmed down zip Maurizio sent me.

I've just take a quick look however I notice that you are using "/index.jsp"
as your alias. In terms of the lookup done this will map a request for
index.jsp to the "/" resource in your Httpcontext. Alias is used as a prefix
to match against so for alias="/index.jsp", if you want to be really sick
try http://localhost/index.jsp/index.jsp. I'd suggest instead to use the
alias "/*.jsp".

Dear Simon,
I cannot believe .... it seems like a VERY stupid thing, does it?

Everything is up-and-running, now!

Thanks a million.
