| Summary: | 0004051: Servlet 3.0 Upload API throws NPE | ||||
| Description: |
When using Servlet 3.0 API for file upload, I get the following NPE: <snip> java.lang.NullPointerException at com.caucho.server.http.HttpServletRequestImpl$PartImpl.write(HttpServletRequestImpl.java:2142) at org.wiztools.fileupload.ServletIndex.doPost(ServletIndex.java:39) at javax.servlet.http.HttpServlet.service(HttpServlet.java:158) at javax.servlet.http.HttpServlet.service(HttpServlet.java:96) at com.caucho.server.dispatch.ServletFilterChain.doFilter(ServletFilterChain.java:109) at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:183) at com.caucho.server.webapp.AccessLogFilterChain.doFilter(AccessLogFilterChain.java:103) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:286) at com.caucho.server.http.HttpRequest.handleRequest(HttpRequest.java:789) at com.caucho.network.listen.TcpSocketLink.dispatchRequest(TcpSocketLink.java:660) at com.caucho.network.listen.TcpSocketLink.handleRequestsImpl(TcpSocketLink.java:624) at com.caucho.network.listen.TcpSocketLink.handleRequests(TcpSocketLink.java:575) at com.caucho.network.listen.TcpSocketLink$AcceptTask.doTask(TcpSocketLink.java:1183) at com.caucho.network.listen.TcpSocketLink$ConnectionReadTask.runThread(TcpSocketLink.java:1118) at com.caucho.network.listen.TcpSocketLink$AcceptTask.run(TcpSocketLink.java:1150) at com.caucho.util.ThreadPool$PoolThread.runTasks(ThreadPool.java:901) at com.caucho.util.ThreadPool$PoolThread.run(ThreadPool.java:866) </snip> This happens only when my Servlet has both doGet() and doPost() method. When I write a Multipart Servlet having only doPost() method, this exception is not thrown. I have created a sample project to test this issue: http://code.google.com/p/servlet30-file-upload/ [^] (Maven based JavaEE 6 Web Project) Only the third upload feature (*With Additional Parameters to Exclusive Servlet*) in this sample application works. |
