| Summary: | 0001010: rewrite-dispatch issues | ||||
| Description: |
(rep by Bill Au) I have two webapps, webapp1 and webapp2, installed in my resin server. For URL that looks like "/webapp1/select", I actually need to have it handed by webapp2 (ie /webapp2/select). So I somehow need to rewrite/map/forward/redirect requests with the URL /webapp1/select to /webapp2/select. I came across <rewrite-dispatch>. I tried putting the following under <host>: <rewrite-dispatch> <forward regexp='^/webapp1/select' target='/webapp2/select'/> </rewrite-dispatch> But got a 500 response: 500 Servlet Exception java.lang.NullPointerException at com.caucho.server.connection.AbstractHttpRequest.getRequestDispatcher(AbstractHttpRequest.java:2016) at com.caucho.server.dispatch.ForwardFilterChain.doFilter(ForwardFilterChain.java:78) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:229) at com.caucho.server.http.HttpRequest.handleRequest(HttpRequest.java:268) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:389) at com.caucho.util.ThreadPool.runTasks(ThreadPool.java:492) at com.caucho.util.ThreadPool.run(ThreadPool.java:425) at java.lang.Thread.run(Thread.java:595) When I tried: <rewrite-dispatch> <redirect regexp='^/webapp1/select' target='/webapp2/select'/> </rewrite-dispatch> I got a different 500 response: 500 Servlet Exception java.lang.NullPointerException at com.caucho.server.connection.AbstractHttpResponse.getAbsolutePath(AbstractHttpResponse.java:633) at com.caucho.server.connection.AbstractHttpResponse.sendRedirect(AbstractHttpResponse.java:557) at com.caucho.server.dispatch.RedirectFilterChain.doFilter(RedirectFilterChain.java:87) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:229) at com.caucho.server.http.HttpRequest.handleRequest(HttpRequest.java:268) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:389) at com.caucho.util.ThreadPool.runTasks(ThreadPool.java:492) at com.caucho.util.ThreadPool.run(ThreadPool.java:425) at java.lang.Thread.run(Thread.java:595) /webapp2/select is mapped to a servlet but there is no mapping for /webapp1/select. Is that the cause of the NullPointerException? Should the RewriteFilter be used instead? |
