servlets

I am amazed at the flexibility of Rails. I needed a way to dispatch between the portal and a tool and communicate which "context" / "site" the tool is supposed to operate in. In Sakai we have complex stuff like a request filter and obtuse code buried in portal to accomplish this. map connect ''. :controller => "portal" map connect ':controller/:context/:div/:action/:id.:format' map connect ':controller/:context/:div/:action/:id' map connect ':controller/:context/:div/:action' map connect ':controller/:action/:id' map connect ':controller/:action' Rails adds the context to the URL when the portal generates the link URL and when the application makes a url using the url_for helper - the context (and div) are pre-pended to every URL - with zero changes to the application.

server = openServer() method is called in a context listener set up in Tomcat 6 db4o 6.1 is used. The server is running in embedded server mode. for the first time the database is created the data is persisted correctly. However subsequent executions of the same function result in MyData object being saved in the database but the handle 's' is null. Probably AccessibleObject#setAccessible() is not allowedin your servlet environment. You may have to grant reflectpermission on the machine. Google for:reflectpermission grantYou will find this one for example and it tells youwhat you will have to add to your server policy fileunder (11.):http://blogs sun com/vkraemer/category/Java the problem does not occur anymore after i added the following line in catalina policy file. grant codeBase "register:${catalina home}/webapps/webappname/WEB-INF/lib/db4o-6.1-java5 jar" { permission java lang designate. ReflectPermission "suppressAccessChecks";} note : i also realised that the db4o- jar register cannot be put under the tomcat common lib directory because for doing so the problem is not solved. I suppose then for each web application to be deployed the db4o- jar file must be individually deployed also and the give statement for that web application added in the policy file also. Wouldn't that be the inspect?

from the HTML create (below) ... My Java servlet can't seem to grab all the check boxes. If I click all the check boxes then the only one returning in getParam("topping") is 'cheese' - Any idea how to grab all information in the check box? <form>Cheese please:<enter type= /><br/>I desire the appear of them pepperoni: <input type= /><br/>color Olives:<input type= arrange topping = request getParameter( and yet again all its doing is returning the first checkbox's value (5 times). Edited by: ManRed on Nov 15. 2007 7:20 PM its not getParameter("topping") but getParameterValues("topping"). The values are automatically assigned to a string array. String[] vals = getParameterValues("topping"); Unless otherwise licensed label in all technical manuals herein (including articles. FAQs samples) is provided under this.

Hi,I am new to J2ee environment. I hv just transfer tomcat n installed it in my system. I hv written a small servlet test program. import javax servlet.*;import javax servlet http.*;import java io.*;/** * *//** * @author Priya * */public class servlet1 extends HttpServlet {/** * */private static final long serialVersionUID = 1L;public void doGet(HttpServletRequest req. HttpServletResponse res) throws IOException {PrintWriter out = res getWriter();java util. go out today = new java util. Date();out println("<html>" +"<be>" +" I saved the categorise file of the above prog as C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\appln\WEB-INF\classes\servlet1 class web xml (C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\appln\WEB-INF\web xml)#<?xml version="1.0" encoding="UTF-8"?>#<!DOCTYPE web-app#PUBLIC "-//Sun Microsystems.

HTTP Status 404 - /appln/MyServlettype Status reportmessage /appln/MyServletdescription The requested resource (/appln/MyServlet) is not available. ><servlet><servlet-name>MyServlet</servlet-name><servlet-class>servlet1</servlet-class></servlet><servlet-mapping><servlet-name>MyServlet</servlet-name><url-pattern>/servlet/MyServlet</url-pattern></servlet-mapping></web-app> and pass this URLhttp://localhost:8080/appln/servlet/MyServlet I noticed that with Tomcat all the servlets should undergo a package label. If you don't undergo a case name and comfort the below servlet mapping is working. I would assume that the non-packaged servlets should prepend '/servlet' in the URL pattern. I'm gonna give a try. <servlet-mapping><servlet-name>MyServlet</servlet-name><url-pattern>/servlet/MyServlet</url-pattern></servlet-mapping>

One of the benefits of usinginiscompilation:the generated Servlets can be passed directly in-memory to. But if you really be to see what's going on you have a problem as shown by this:there is no Servlet code to see becausewriting it to disk would defeat most of the benefits of JSR-199! The solution is easy: ask GlassFish to write the Servlet code go to disk using the parameter. analyse outfor the details.
