I have a servlet that is not mapping to my URL:
<servlet-mapping>
<servlet-name>view</servlet-name>
<url-pattern>/View/*</url-pattern>
</servlet-mapping>
When I try to call the Servlet from a JSP:
<a href="/View/viewFlow?V1">V1</a>
The resulting link is [URL].... It's bypassing the project name. The link should be [URL]...
I have this mapping:
<servlet>
<servlet-name>wsdl</servlet-name>
<jsp-file>/wsdl/bankconnect.html</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>wsdl</servlet-name>
<url-pattern>/wsdl</url-pattern>
</servlet-mapping>
And this works fine: URL....The war file is deployed under the context root /bankconnect/ I want to make a servlet mapping, before the context root "i still want the context root bankconnect". URL....
We generally use [URL] ..... for running web applications.
What I want is to access my web app using something like this: [URL] ....
How to achieve this? Actually what i want to ask is that how URL like WWW.example.com is mapped to web applications? Assuming that i am using tomcat server.
When I map my servlet to the ROOT of the site, the javascript, CSS and image files are not served. The conversation between the server and browser shows the files are being sent, but they are not rendered in the browser. This happens in both Firefox and Chrome.
If I change the mapping to anything other than the root, such as /x/, everything works as it should.
Here's my web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
[Code] .....
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter pw = response.getWriter();
String connectionURL = "jdbc:mysql://localhost:3306/userdb";// userdb is the database
Connection connection;
[Code] .....
When casting a char which is read from a file to an int, can i assume that the mapping used will be ASCII? I've learned that unicode uses ASCII mappings for the characters that overlap.
Are there any other possibilities for int values of one character? I still have trouble understanding character encodings.
I am writing a program where I need to split an array of full names into First names and Surnames, using mapping. However, I am struggling how to split it up... and my First Names and Surnames list are both just displaying the full name.
public static void main(String[] args) {
String[] names;
names = new String[8];
Scanner s = new Scanner(System.in);
for (int i = 0; i < names.length; i++) {
System.out.println("Enter full student name:");
[Code] ....
I'm working on a project and I'm just about to implement different stages (menus etc). The program is opened in an intro stage that just renders a text (slick, Unicode font) looking like this:
After switching to a different stage hat uses shadow mapping and then back to the intro stage it looks like this:
I've found that removing the line:
glCopyTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT, 0, 0, shadowMapWidth, shadowMapHeight, 0);
solves the problem but then the shadow mapping isn't working.
I'm looking for a working example of shadow mapping with java code using shaders. There are so many c++ or c tutorials out there but i haven't managed to rewrite them since I'm too bad in c/c++. I've been trying to implement this a long time but can't get the hang of it. Any example out there? Preferably as sstripped down as possible except for the shadow mapping.

We need to process (read and parse) big xml files (500 Mo to 1 or 2 Go). What's the best framework or Java library to use for this requirement ? Then what's a good OXM (in this case xml to object mapping) solution for this kind of file ?
View Replies View RelatedI have downloaded and testing these two mapping libraries. I wrote a program which has 100000 iterations and maps the beans of the same class:
public class IntBean {
@JMap
private int int1;
@JMap
private int int2;
[Code] ....
Mappers are created BEFORE iterations start:
private JMapper jmapper = new JMapper(IntBean.class, IntBean.class);
private MapperFactory orikaFactory = new DefaultMapperFactory.Builder().build();
private MapperFacade orikaFacade = null;
orikaFactory.registerClassMap(orikaFactory.classMap(IntBean.class,IntBean.class).byDefault().toClassMap()); orikaFacade = orikaFactory.getMapperFacade();
What is in each iteration:this.orikaFacade.map(a1, a2);
or
a2 = (A) this.jmapper2.getDestination(a1);
I know, that Orika and Jmapper are great libraries from Google and they use reflection in a different way than for example Dozer, which is much slower, they se reflection to generete code somehow..
I have 3 questions:
1) How they work - when the code is generated, during maven build, in runtime - everytime when I create mapper in code? Are they change class code byte dynamically?
2) Why there is this speed difference that I noticed?
3) Which library would you choose and why? Both have the same capabilities? Why both come from Google? Why Google didnt develop Orika and created Jmapper instead?
So, i got the following code:
@Path("{bill-id}/request")
@Path("{user-id}")
and the following pattern
myhost/c15a856/request
somehow, the container always decides to match it to @Path("{user-id}"). How do I resolve this
I am trying to use iText to create a PDF document. I found a nice tutorial online but one thing stumps me. How do I get the URL of the JSP page that contains the content? Since this will not be static, I don't want to hard code this. I am sure this is something simple but I am fairly new to servlets and JSP.
String File_To_Convert = "test.htm";
How do I get the url of the JSP page?
Is it permitted or possible to use annotations on classic servlets?
E.g.:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
[Code] ....
I tried to visit my webapp with /appinfo appended after the context url but I get a 404 and I see no errors in the GlassFish4 log.
My project is using JSF 2.x with the viewservlet mapped on *.xhtml and it is using Spring Beans as well (using the Spring Context Loader), mapped to /rest/*. Do I need to map something else?
I can only get this servlet working without annotations but only using the old web.xml way.
I don't know what I need to do to get my servlet working with annotations.
I have my mapping as below
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>co.edureka.controllers.MainController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>main</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
So that I can map the first request coming say www.xyz.net to my first page , it does the work but some of my css and images is not getting displayed .
So I did as below
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>co.edureka.controllers.MainController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>main</servlet-name>
<url-pattern>/first</url-pattern>
</servlet-mapping>
By doing this my css and images get displayed and everything works fine.
But the problem is I want to display my first page as user puts the url.
I am putting my jsp pages in WEB-INF/jsps , I am not putting it directly under WEB-CONTENT directory.
I am new to Servlets and came across it in Head First Java 2nd Edition. I wrote the servlet code. I don't know how to run it. Do I need to set up a server?
View Replies View RelatedSuppose we have two servlets runing inside same war on same server. When user access servlet A and create a session, he then open another tab or browser to access servlet B (session created by servlet A still exist). Inside servlet B, does
request.getSession()
return the session created by servlet A ?
I'm trying to go back to basic and strengthen some of my foundation. I'm wondering what kind of data would be appropriate to be stored inside a session? My app is a web app where all the users are the employee of a company. So it's an web-based app that keeps track of stock movements, purchasing and sales order (standard distributor company). The web app interacts strictly with employees, so no public facing app (yes, that's right, no shopping cart). So, in this kind of web app, what kind of data that by storing it to session.
View Replies View RelatedI am calling a jsp page from my servlet using the requestdispatcher.forward(myjsp.jsp) method. myjsp.jsp is creating a new thread which is parallely processing along with the servlet. The issue is that the jsp page is not displayed until the servlet finishes its execution, although the new thread is created by jsp and is executing in parallel. How do we have the jsp page displayed even when the servlet is executing.
View Replies View RelatedI have a secured Struts application in WebSphere that uses FORM j_security_check for authentication.There is also a Post Logon "filter" defined which runs some code after a login is processed.The extract from web.xml showing the login configuration and filter is as follows:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>MyRealm</realm-name>
<form-login-config>
<form-login-page>/login.html</form-login-page>
<form-error-page>/error.html</form-error-page>
[code]....
If a user isn't logged into the application and they try to access one of the secured servlets, for example quotes.do, they are directed to the login page to enter their information.If they login successfully, they are then directed to quotes.do, rather than the default "welcome" page. Is there a setting in the web.xml or the post logon filter where I can force j_security_check to ALWAYS go to the default welcome page after a successful login?
I need to encode the URL in order to prevent XSS security threat. I don't have to encode the complete URL, I just have to encode the values for query string. How to encode only the values of query string parameters and change it in the URL itself using java. I am planning to do this in a filter.
View Replies View RelatedI am trying to finish this servlet that adds a new course to my courses display. im using a check box so the user can pick what the prerequisite are for the new course they want to add. so if they check cs201 , it will add cs201 as a prerequisite for that new course.
for some reason my checkbox will only add the first checkbox that is clicked. like if i add a subject , and click the check boxs for cs203 , cs202, and cs201. it will only grab cs201 and add it to my course display. it wont grab all 3. how can i grab the other info thats checked?

I did a Servlet and a JSP with a combobox. I called the JSP on one browser and selected value n1 from the combobox. From another computer, I called the (same URL) and selected value n2. I expected the Servlet to handled both requests separately, however when I select value n2 on the 2nd browser, the jsp on the 1st browser that initially had value 1, now changes into value 2 as well.
Why cant the servlet handle requests separately? users actions on different browsers should not interfere with each other..!
