Http Whiteboard
I've in the process of trying to convert a couple of servlets over to user HttpWhiteboard. I looked online for an example and it seemed pretty straight forward.
Based on my understanding, I came up with the following but it doesn't work. Jetty doesn't have a myApp context. I assume there is something missing?
Help?
Scott
@Component(
property = {
HTTP_WHITEBOARD_CONTEXT_NAME + '=' + ContextHelper.CTX_NAME,
HTTP_WHITEBOARD_CONTEXT_PATH + '=' + ContextHelper.CTX_PATH
}
)
public class ContextHelper
extends org.osgi.service.http.context.ServletContextHelper
{
public static final String CTX_NAME = "myApp";
public static final String CTX_PATH = '/' + CTX_NAME;
}
@Component(
name = "myApp.listings",
property = {
HTTP_WHITEBOARD_CONTEXT_SELECT + "=(" + HTTP_WHITEBOARD_CONTEXT_NAME + '=' + ContextHelper.CTX_NAME + ')',
HTTP_WHITEBOARD_SERVLET_NAME + '=' + "MyApp Listings",
HTTP_WHITEBOARD_SERVLET_PATTERN + '=' + "/list/*"
},

One thing I forgot about the working example:
- I need to have HTTP whiteboard loaded when I start the servlet
components
I accomplish this by adding a dependency to the pax-http-whiteboard
feature in the template karaf feature files of the bundles holding the
DS components that contain services that want to register with the HTTP
whiteboad:

Here is a working example:
1. This defines the web context "/ukelonn" (and attaches a shiro filter
to the web context)
https://github.com/steinarb/ukelonn/blob/8442f5df62bc973902085705c637e65c3bc00f8c/ukelonn.web.security/src/main/java/no/priv/bang/ukelonn/web/security/UkelonnServletContextHelper.java#L7

2. Here are servlets that register with the webcontext
https://github.com/steinarb/ukelonn/blob/8442f5df62bc973902085705c637e65c3bc00f8c/ukelonn.web.services/src/main/java/no/priv/bang/ukelonn/api/UkelonnRestApiServlet.java#L37
https://github.com/steinarb/ukelonn/blob/8442f5df62bc973902085705c637e65c3bc00f8c/ukelonn.web.frontend/src/main/java/no/priv/bang/ukelonn/web/frontend/UkelonnServlet.java#L36
The syntax for registering with the context ie.
HttpWhiteboardConstants.HTTP_WHITEBOARD_CONTEXT_SELECT + "=(" + HttpWhiteboardConstants.HTTP_WHITEBOARD_CONTEXT_NAME +"=ukelonn)",
is a bit clumsy, but it works.
(I have on my todo list to figure out if the servlet API 3.0 annotations
can be used instead...)

I’m a bit confused. I’m doing this with OSGi R6 so the URL pattern list has to be the latter part of the string created by:
HTTP_WHITEBOARD_SERVLET_PATTERN + ‘=’ + PATTERN_LIST
does it not?

You can have multiple patterns just by adding the property as a String[]/Collection. See https://osgi.org/javadoc/osgi.cmpn/7.0.0/org/osgi/service/http/whiteboard/propertytypes/HttpWhiteboardServletPattern.html#value-- which is the component property type for that whiteboard property.
If you can’t use component property types then repeated single value entries in the property element get aggregated into an array.

Perhaps that’s related to something else and the presence/absence of Web-ContextPath is triggering the other issue. I’ll see what I can figure out in that regard.
I do have one last question though. I’m wondering what the syntax is to associate multiple URL patterns with a single servlet. I assume I can use wildcarding and stuff like that but can I use a Java RE? How about a URL list? Comma separated, bounded by braces, brackets?
I’m thought I had a copy of the R6 compendium squirreled away so that I could just look it up but it may be on my machine at home and for some reason I’m not seeing it at osgi.org<http://osgi.org/> even though I’m sure it’s there somewhere.

Thanks Tim,
That’s exactly what I thought but without it I get the following from Jetty.
HTTP ERROR 404
Problem accessing /myApp/. Reason:
Not Found
Perhaps that’s related to something else and the presence/absence of Web-ContextPath is triggering the other issue. I’ll see what I can figure out in that regard.
I do have one last question though. I’m wondering what the syntax is to associate multiple URL patterns with a single servlet. I assume I can use wildcarding and stuff like that but can I use a Java RE? How about a URL list? Comma separated, bounded by braces, brackets?
I’m thought I had a copy of the R6 compendium squirreled away so that I could just look it up but it may be on my machine at home and for some reason I’m not seeing it at osgi.org even though I’m sure it’s there somewhere.

Hi Scott,
sorry for the later answer, I was traveling yesterday.
You have an example in the Karaf distribution:
https://github.com/apache/karaf/tree/master/examples/karaf-servlet-example/karaf-servlet-example-annotation
We also have an example in Winegrower:
https://github.com/jbonofre/winegrower/tree/master/winegrower-examples/http
Basically, if you register a Servlet service with name and urlPatterns
as service properties, and you have the http-whiteboard feature
installed, it should work straight forward.
Regards
