View Replies View RelatedJSF :: Extension Of Pages In URL?
Jan 22, 2014 I am working in JSF and I've forgot few of the basics :'I use eclipse IDE to develope JSF projects. When I used to create a JSF file, it's extension is basically .jsp and when I ran that file in server .jsf extension used to be displayed in url. But recently, when I did the same thing I got .jsp extension in browser. in web.xml
when url-pattern is the following, .jsp extension is shown, eg: FileName.jsp
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
but when I change the url-pattern as per following, .jsf extention is shown , eg: FileName.jsf
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
even if I change the url-pattern to abc or xyz, the webpage url is shown in that format. eg: FileName.abc this is the actual scenario to specify extension of a jsf page, or is this an error.

View Replies View RelatedJSF :: Passing Argument Parameters Between Pages
Jul 19, 2014So I have an application where the user logs in (using j_security_check). User is taken to a welcome page where user's name is displayed as a link. When clicking that link I would like to take the user to a page where the user is able to update the credentials (password, address, etc). In this way the user only has access to the link related to that specific user's credentials. I am trying the following structure:
The welcome page (adminindex.xhtml) is:
<h:form>
Welcome to admin <h:commandLink value="#{userb.loggedUser}" action="#{userb.selectedUser}"/>
<f:param name="userName" value="#{userb.userName}"/>
</h:form>
The user backing bean:
public String selectedUser() {
userName = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get(userName);
selUser=uServ.findByName(userName);
return "UpdateUser";
[Code] ....
The last line of the stack suggests that a null PK value is being picked up by the FacesContext method in the backing bean. I'm confused because the userName string IS the primary key of the user table which is structured like this:
CREATE TABLE sha_users
( username VARCHAR(255) NOT NULL
, password VARCHAR(255) NULL
, PRIMARY KEY ( username ) );
I'm sure I'm getting the concept of how to pass query parameters...

View Replies View RelatedJSF :: How To Render More Than One JSP Pages Into 1 Single View
May 15, 2014I have an application where the WebContent folder has a number of .jsp pages like navigation.jsp, primarytabs.jsp etc.
The navigation.jsp contains a vertical menu and the primarytabs.jsp contains a tab on top, and some other jsps contain individual components.
When I run the application of the application server, it opens up a welcome page, and all these navigation items, and tabs and others merge into a single view and show us a well formed combination of all these components.
I did some studying and read about "composite views". But I wasn't sure if I can call this composite view or not.
How JSF combines all these jsps into one view and where to find that "binding" within the code so I can make the relevant changes?
Servlets :: How To Check For A Session As The User Goes Through Different Pages
Mar 18, 2014I have a question about how to check for a session as the user goes through different pages. I am using Java beans and EL to pass data from page to page but I cannot figure out how to check for a session on the pages without the use of a scriptlet with an if else statement in it.
I do not want the user to be able to access any pages unless they are logged in. With a scriptlet, I can create a statement that says if session exists show name else redirect to login page.
From what I have read and what some of the wonderful members here have told me, scriptlets are a big no no these days. So, how do I do these without the use of a scriptlet?

Use Various Freemarker Templates To Create Web Pages For Website
Feb 23, 2014I have a Java application and it uses various Freemarker templates to created Web pages for a Web site. Here is a snippet of one of my Freemarker templates that will display the fee description, fee charge, and an add button. The fee has to do with charges that pertain to automobiles. When I click on the "Add" button, I will be taken to another Web page. How would I send the fee.description and the fee.charge to the other page when I click on the "Add" button?
<tr class="${rowclass}">
<td class="leftalign">${Fee.description}</td>
<td class="centeralign"><#if Fee.charge??><#if Fee.charge?trim?upper_case != "No Charge"?trim?upper_case && lot.workOrderFee.charge?trim?upper_case != "Market Price"?trim?upper_case >$</#if>${Fee.charge}</#if></td>

Renaming Individual Extracted Pages Files From Single Booklet PDF In Correct Sequence
Sep 7, 2014I have huge PDF files which are in booklet format. Example:
Assume a booklet pdf file has 24 pages which each page contains 2 pages which is in two sides - left side and right side.
The first page has 48th page number on the left side and 1st page number on the right side
The second page has 2nd page number on the left side and 47th page number on the right side
The third page has 46th page number on the left side and 3rd page number on the right side
I have vertically cut the Booket PDF files in to separate individual PDF files using bulk operation in separate folder.
for example, the cutted PDF file will be as follows in the above case
1st pdf file - 48th page
2nd pdf file - 1st page
3rd pdf file - 2nd page
4th pdf file - 47th page
5th pdf file - 46th page
6th pdf file - 3rd page..
Similarly for other PDF files too....if a PDF file has 95 pages....
the first page has 95th page number on the left side and 1st page number on the right side
Now the issue is how to rename and arrange the files correctly in the sequence for EACH PDF file so that we can merge the PDF file as one at last for each PDF file...
After renaming correctly in the proper sequence for the above file
1st pdf file should point to 1st page
2nd pdf file should point to 2nd page
3rd pdf file should point to 3rd page...
The problem is all the PDF files which we are planning to split will have different set of pages..example
PDF1 file - has 48 pages as above -> files should be renamed and arranged as 1, 2, 3, 4...48 correctly
PDF2 file - has 96 pages -> files should be renamed and arranged as 1, 2, 3, 4.....96 correctly
PDF3 file - has 56 pages -> files should be renamed and arranged as 1, 2, 3, 4.....56 correctly
Program which will rename the vertically cutted files in a proper sequence??
Java Application With Several Classes All In Same Java File
Apr 9, 2015I've written a java application with several classes all in the same .java file. It works just fine. Now, I've broken it up so that each class has its own .java file. Still works fine. My next step is to put those classes into a package, but I'm not about to get the program to run.The .java source files are all in /home/user/src
I've set the CLASSPATH to /home/user/src..All of the source files have "package com.myfirm.program" on the first line.I compiled the application with:
javac -d . File1.java File2.java File3.java (etc...)
the compiler created the directory: /home/user/src/com/myfirm/program and put all of the .class files in there.So how do I get the program to run? if I run from /home/usr/src
java File1
I get: Exception in thread "main" java.lang.NoClassDefFoundError: File1 (wrong name: com/myfirm/program/Program)
Make A Calculator Using Java GUI
Jul 29, 2014I am trying to make a calculator using Java GUI. I've managed to make an ActionListener and add it to a button, but I've made an error in my code that I'm unsure of how to solve. Because of how I've written the code, only one number can be placed in the text field. For example, the an ActionListener for the three button on the calculator was added to the button, but no matter how many times the user presses the button, only one 3 will appear in the text field. The code is below:
import javax.swing.*;//import the packages needed for gui
import java.awt.*;
import java.awt.event.*;
public class Calculator {
public static void main(String[] args) {
JFrame window = new JFrame("Window");//makes a JFrame
window.setSize(300,350);
[code].....
As you can see, because the compiler forces the String variable to be final, so when the user presses the button, the code simply shows how a space character and three character would look like, because the String variable can't change. How do I write my code so that every time the user presses the button, a character is added to the text field?
