Hi,

Thank you for sharing the fix. Would you please open a JIRA at http://issues.apache.org/jira/browse/TUSCANY and contribute your patch there?

      Hi again,

      After a lot of debugging I've found what's happening with JBoss (any version surely) and Tuscany. Here it goes:

      1. We are at ContributionServiceImpl of the Tuscany 1.3.2 source, lines 357-369.
      2. URL points to the directory of the calculator war deployed in JBoss.

      - When running in JBoss the URL.getConnection() returns an instance of sun.net.www.protocol.file.FileURLConnection. The FileUrlConnection when invokes the getInputStream() tries to instance a FileInputStream. Here URL points to a directory (calculator-sample-webapp.war), then FileInputStream throws a FileNotFoundException (see FileInputStream signature in javadocs). On windows machines the error message is 'Access Denied' (?) and on Unix machines the error message is 'Is not a Directory' (more accurate).

      After reading all sources of PackageProcessor (the ones using the InputStream obtained from the URLConnection) I've seen that only JarContributionProcessor uses the InputStream object. FolderContributionProcessor, the one who reads directories, don't uses the InputStream object.

      Then, temporary, I've changed the code to:

              try {
                  if (!new File(sourceURL.toURI()).isDirectory()) {
                  // lines 357 to 369
                  }
              } catch (URISyntaxException ex) {
                  ex.printStackTrace();
              }
              
      And it worked fine.

      - When running in Tomcat it works fine because URL.getConnection() returns an instance sun.net.www.protocol.file.FileURLConnection and a java.io.ByteArrayInputStream when the getInputStream() method is called.

      - I think a JIRA is needed to better solve this situacion for JBoss servers.

      Bye and hope that helps others.

      Jose Luis
