Writing scalable server applications in the Java™ programming language has always been difficult. Before the advent of the Java New I/O API (NIO), thread management issues made it impossible for a server to scale to thousands of users. The Grizzly NIO framework has been designed to help developers to take advantage of the Java™ NIO API.

ServletContextImpl return null for resource #615

Closed glassfishrobot closed 14 years ago

glassfishrobot commented 15 years ago

I'm trying to compile a JSP with jasper, but the resource is always null.

try to get resource from com.sun.grizzly.http.servlet.ServletContextImpl.java where path = "/demo/jsp/index.jsp" public InputStream getResourceAsStream(String path)

{ path = normalize(path); if (path == null) return (null); return Thread.currentThread().getContextClassLoader() .getResourceAsStream(path); }

Environment

Operating System: All Platform: All

Affected Versions

[1.9.22]

// Create the ROOT context this.rootcontext = this.embedded.createContext("/demo", "c:/workspace_personal/JSPSupport/demo"); this.rootcontext.setReloadable(false); this.rootcontext.addWelcomeFile("index.jsp"); this.host.addChild(this.rootcontext);

String[] aliases = new String[]

String context = "/demo"; String servletPath = "/jsp"; String rootFolder = "c:/workspace_personal/JSPSupport/demo";

ServletAdapter adapter = new ServletAdapter(); Servlet servlet = (Servlet) ClassLoaderUtil.load("org.apache.jasper.servlet.JspServlet"); adapter.setServletInstance(servlet);

adapter.setContextPath(context); adapter.setServletPath(servletPath); adapter.setRootFolder(rootFolder);

it will set the Servlets from his default web.xml. (*.jsp)

WebAppContext webappcontext = new WebAppContext(); webappcontext.setContextPath("/"); webappcontext.setWar(rootFolder);

HandlerList handlers = new HandlerList();

handlers.setHandlers(new Handler[]

); server.setHandler(handlers); server.start();

String url = context + servletPath + "/index.jsp"; HttpURLConnection conn = getConnection(url); assertEquals(HttpServletResponse.SC_OK, getResponseCodeFromAlias(conn));

String response = readResponse(conn).toString();

System.out.println("response=" + response);

assertEquals(url, response.trim());

server.stop(); }

survivant@java.net said: I think we still have a problem when the jsp path are not in the classpath (not resources)

try to run the testcase :JSPSupportTest from my JSPSupportDemo (rar file)

survivant@java.net said: I did some changes to my test by adding the root folder to the classpath and it works.

String context = "/ctx"; String servletPath = "/demo/jsp"; String rootFolder = "c:/workspace_personal/JSPSupport/";

GrizzlyWebServerDeployer deployer = new GrizzlyWebServerDeployer(); deployer.appendWarContentToClassPath("c:/workspace_personal/JSPSupport/");

I'll try tonight more tests.
