Я запускаю Jetty на платформе Android для обслуживания статических html-страниц и сервлета. Теперь я попытался добавить поддержку страниц JSP, но у меня есть это исключение, когда я запрашиваю любой jsp:
HTTP ERROR 500
Problem accessing /time.jsp. Reason:
Server Error

Вот мой код конфигурации из основного действия:
public void startServer()
{
server = new Server(8080);
System.setProperty("org.apache.jasper.compiler.disablejsr199", "true");
// Create a resource handler for static content.
ResourceHandler staticResourceHandler = new ResourceHandler();
staticResourceHandler.setResourceBase(Environment.getExternalStorageDirectory().getAbsolutePath() + "/web/static/");
staticResourceHandler.setDirectoriesListed(false);
// Create context handler for static resource handler.
ContextHandler staticContextHandler = new ContextHandler();
staticContextHandler.setContextPath("/static");
staticContextHandler.setHandler(staticResourceHandler);
// Create WebAppContext for JSP files.
WebAppContext webAppContext = new WebAppContext();
webAppContext.setContextPath("/");
webAppContext.setResourceBase(Environment.getExternalStorageDirectory().getAbsolutePath() + "/web/");
webAppContext.setInitParameter("org.eclipse.jetty.servlet.Default.dirAllowed", "false");
// Create servlet context handler for main servlet.
ServletContextHandler servletContextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);
servletContextHandler.setContextPath("/servlet");
servletContextHandler.setResourceBase(Environment.getExternalStorageDirectory().getAbsolutePath() + "/web/servlet/");
terminalServlet = new TerminalServlet(this);
networkServlet = new NetworkDrawerServlet(this);
servletContextHandler.setClassLoader(Thread.currentThread().getContextClassLoader());
servletContextHandler.addServlet(new ServletHolder(terminalServlet),"/terminal");
servletContextHandler.addServlet(new ServletHolder(networkServlet),"/topology");
//servletContextHandler.addServlet(new ServletHolder(new DefaultServlet()), "/*");
// Create a handler list to store our static, jsp and servlet context handlers.
HandlerList handlers = new HandlerList();
handlers.setHandlers(new org.eclipse.jetty.server.Handler[] { staticContextHandler, webAppContext, servletContextHandler });
// Add the handlers to the server and start jetty.
server.setHandler(handlers);
try {
server.start();
} catch (Exception e) {
}
}
Я помещаю файлы веб-сервера (статический контент и файл jsp) в каталог «/web/» во внешнем хранилище (и это работает для статического контента, я установил права чтения и записи в файле манифеста).
Я думаю, что это общая проблема конфигурации под Android, потому что тот же код, скомпилированный и выполненный на рабочем столе, работает нормально.
