Hello Michael,
if its within same webapp (I presume it is), you can use
ContainerRequestFilter - short sample:
// redirects *helloworld to *helloworld/something
public class MyFilter implements ContainerRequestFilter {
@Override
public ContainerRequest filter(ContainerRequest request) {
try {
if(request.getAbsolutePath().toString().endsWith("helloworld")) {
request.setUris(request.getBaseUri(),
request.getRequestUriBuilder().path("something").build());
}
return request;
} catch (Exception e) {
// add proper handling
}
return null;
}
}
I have to admit I don't really know why your case don't work, but it
might be meant for lower level use / redirecting to another
servlet/filter maybe.. not sure. Anyway ContainerRequestFilter should
work for you (but its Jersey specific). See
http://jersey.java.net/nonav/apidocs/1.11/jersey/com/sun/jersey/spi/container/ContainerRequestFilter.html.
Regards,
Pavel
