Apache Felix HTTP service HttpServiceImpl.isNameValid does not match OSGi R4.2 spec?

[Misha Koshelev]

Dear All:

Thank you all for your help and patience with me.

I am working on the following OpenMRS ticket:
http://tickets.openmrs.org/browse/TRUNK-1596

I am trying to use Apache Felix instead of Spring DM Web Extender.

I have had some problems with JSP support, and am trying to use the
Equinox JSP bundle:
http://www.eclipse.org/equinox/server/jsp_support.php
with Felix, specifically using the bridge sample in 2.0.4. I have
double checked code in trunk.

I _am_ successful with Equinox servlet bridge, see:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=329706

However, this example:
http://prdownloads.sourceforge.net/sse-examples/org.eclipse.equinox.jsp.examples-proj.zip?download

contains the following lines in org.eclipse.equinox.jsp.examples.Activator:

                                HttpContext commonContext = new
BundleEntryHttpContext(context.getBundle(), "/web"); //$NON-NLS-1$
                                httpService.registerResources("/jsp-examples", 
"/",
commonContext); //$NON-NLS-1$ //$NON-NLS-2$

                                Servlet adaptedJspServlet = new 
ContextPathServletAdaptor(new
JspServlet(context.getBundle(), "/web"), "/jsp-examples");
//$NON-NLS-1$//$NON-NLS-2$
                                
httpService.registerServlet("/jsp-examples/*.jsp",
adaptedJspServlet, null, commonContext); //$NON-NLS-1$

Felix bridge complains:

java.lang.IllegalArgumentException: Malformed resource name [/]
        at 
org.apache.felix.http.base.internal.service.HttpServiceImpl.registerResources(HttpServiceImpl.java:105)
        at 
org.eclipse.equinox.jsp.examples.Activator$HttpServiceTracker.addingService(Activator.java:38)
        at 
org.osgi.util.tracker.ServiceTracker$Tracked.trackAdding(ServiceTracker.java:1030)

The relevant code, in trunk, is, from
http://svn.apache.org/repos/asf/felix/trunk/http/base/src/main/java/org/apache/felix/http/base/internal/service/HttpServiceImpl.java


 public void registerResources(String alias, String name, HttpContext context)
        throws NamespaceException
    {
        if (!isNameValid(name)) {
            throw new IllegalArgumentException( "Malformed resource
name [" + name + "]");
        }
...

and


private boolean isNameValid(String name)
    {
        if (name == null) {
            return false;
        }

        if (name.endsWith( "/" )) {
            return false;
        }

        return true;
    }

However, the R4.2 enterprise spec from
http://www.osgi.org/Download/File?url=/download/r4v42/r4.enterprise.pdf
on page 48 clearly states:

The name parameter must also not end with slash (’/’) with the
exception that a name of the form “/” is used to denote the root of
the bundle.

Should isNameValid not read, similar to isAliasValid, in the same file:

    private boolean isNameValid(String name)
    {
        if (name == null) {
            return false;
        }

        if (!name.equals("/") && ( !name.startsWith("/") ||
name.endsWith("/"))) {
            return false;
        }

        return true;
    }

???

Thank you

Yours
