Here is the relevant change of ServletServiceContext#getResource(String 

old implementation:

public URL getResource(String path) throws MalformedURLException {
     // hack for getting a file protocol or other protocols that
     // can be used as context
     // path in the getResource method in the servlet context
     if (!(contextPath.startsWith("file:") || contextPath.startsWith("/")
           || contextPath.indexOf(':') == -1)) {
         SourceResolver resolver = null;
         Source source = null;
         try {
           BeanFactory factory = 
           resolver = (SourceResolver)
             source = resolver.resolveURI(contextPath);
             contextPath = source.getURI();
         } catch (IOException e) {
             throw new MalformedURLException("Could not resolve "
                 + contextPath + " due to " + e);
         } finally {
             if (resolver != null) {

     // HACK: allow file:/ URLs for reloading of sitemaps
     // during development
     if (this.contextPath.startsWith("file:")) {
         return new URL("file", null,
           this.contextPath.substring("file:".length()) + path);

     if (this.contextPath.length() != 0 && this.contextPath.charAt(0)
          != '/') {
         throw new MalformedURLException("The contextPath must "
             + "be empty or start with '/' " + this.contextPath);

     // prefix the path with the servlet context resolve and
     // resolve in the embedding
     // servlet context
     return super.getResource(this.contextPath + path);

new implementation:

public URL getResource(String path) throws MalformedURLException {
     if (path == null || !path.startsWith("/")) {
         throw new MalformedURLException("The path must begin " +
                 + "with a '/' and is interpreted "
                 + "as relative to the current context root.");

     // lazy initialization of the base URL
     synchronized (this) {
         if (this.contextPathURL == null) {
             this.contextPathURL = new URL(this.contextPath);

     return new URL(this.contextPathURL, path.substring(1));

The problem with the old SSF was that it _only_ worked, if it was used 
together with Cocoon 2.2. After this change the SSF completely relies on 
the standard URL handling and can really be used now in every 
environment and not only together with Cocoon 2.2.

This requires some changes in Cocoon (-> use JNet to resolve 
blockcontext:/ URLs) but since we can be sure that nobody else than 
Cocoon 2.2 was able to use the SSF 1.0, I think that a release of 1.1 is 
appropriate in this case.

I will synchronize our refactorings of JNet with the code in Apache 
Commons - I hope that somebody else has some time to cut the actual release.

yes, definitely. I use it in all web projects, not only in my Cocoon 
based ones.

I can't promise too much but I will see what I can do.

I will create the release artifacts tomorrow or on Tuesday.
