weblets similar fuctionality in seam?

[jbuechel]

Just a short question (although i did a quite long research in forums):

Is there a weblets similar functionality in JBoss Seam or a4j?
I'm on the verge of including weblets to my project but i'm not very happy about including another library and configuration stuff..

Information would be very appriciated.

Take a look at the Seam Resource Servlet. It doesn't work exactly like weblets, but it solves a very similar problem.

Thanks for the hint, Norman!

It's quite simple and pretty much that what i was looking for.

Here is some code for interested ones:

@Startup
@Scope(ScopeType.APPLICATION)
@Name("fwcResource")
@Install(precedence = Install.BUILT_IN)
@BypassInterceptors
public class FwcResource extends AbstractResource {

 //Has to start with the url-pattern of Seam Resource Servlet mapping in web.xml
 public static final String WEB_RESOURCE_PATH = "/seam/resource/fwc";
 private static final String RESOURCE_PATH = "/fwc";

 @Override
 public String getResourcePath() {

 return RESOURCE_PATH;
 }

 @Override
 public void getResource(HttpServletRequest request,
 HttpServletResponse response) throws ServletException, IOException {

 String pathInfo = request.getPathInfo().substring(
 getResourcePath().length());

 InputStream in = Resources.getResourceAsStream(
 "/com/test" + pathInfo,
 getServletContext());

 if (in != null) {
 byte[] buffer = new byte[1024];
 int read = in.read(buffer);
 while (read != -1) {
 response.getOutputStream().write(buffer, 0, read);
 read = in.read(buffer);
 }
 response.getOutputStream().flush();
 } else {
 response.sendError(HttpServletResponse.SC_NOT_FOUND);
 }

 }

}

Or just leave this constant if you don't need:

 //Has to start with the url-pattern of Seam Resource Servlet mapping in web.xml
 //public static final String WEB_RESOURCE_PATH = "/seam/resource/fwc";
