Use Various Freemarker Templates To Create Web Pages For Website
Feb 23, 2014
I 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?
I am working on a project for a store. I need to accept the purchased items from the user and an automatic cash memo would be generated. Now I have an experience with building desktop applications before and have managed to build up the UI. Presently I am stuck in creating a template for the invoice/memo (whatever you may call it). I have the following requirements:
1) How do I create a good template for invoice/memo with the company logo ??? Do I have to rely on any third party software? Any detailed tutorial would be useful.
2) How do I convert that invoice/memo to a pdf file???
I have a random list of links whose title I am getting from the database. I'd like to catch one of these links when the user clicks one of them and process it from a single jsp file. Possible?
E.g.: when user clicks one of these links, can I dynamically call a web page that fetches information from the click and gets values from a database and insert it on JSP page....
I am working with Netbeans 8.0 and JSF2.2. I am trying to create a web site that has a common header, footer, and menu. The only part that would be dynamic is the content. So here goes...
1) I need a common template that has 4 parts, Header, Footer, Menu, Content 2) The header, footer and menu are to be in a separate files of which are called from the main template 3) The content will change based on the menu item changed 4) The menu has to change the content section only
I know how to do this in HTML but I am trying to set up some thing in JSF to learn more on JSF pages. All I am looking for is an example that I can follow along with having the multiple pages as well having the menu change the content (I have done a ton of internet searching but nothing really fits the bill).
This is the code I have currently.
Index (Main Template) <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://xmlns.jcp.org/jsf/facelets" xmlns:h="http://xmlns.jcp.org/jsf/html">
Its required to create a service to embed widgets on any foreign website(server), using servlets where i'll pass encrypted widgetId and in turn i will get html for displaying it on screen. Also a refresh button with the embedded widget is to be provided so as to fetch updated computed data. The point is that user should copy some html/script code and place it on his website.
I am thinking of following approach.An empty span with id, followed by a js script to make ajax call to the server to get widget HTML.
I'm wondering if there's a way to build a template for managed beans which could be extended by a constructor instead of re-writing beans for each entity. I can do that quite easily for Dao objects by creating facades and using those facades to create Dao implementations for specific entities. Not sure if the same concept works for managed beans and haven't really come accross any searches.
I wrote the following but I'm not sure how to implement or even if the concept of generics and templating can be applied to managed beans in the same way it can be applied to Dao classes:
public class BeanTemplate<T> { private ListDataModel<T> listModel; @EJB private GenDao dao; private Class<T> entityClass;
[Code] .....
The above assumes there's only one method needed in the bean. I thought of extending like this:
public class EmployeeBean extends BeanTemplate<Employee> { public EmployeeBean() { super(Employee.class); }
// how can the methods be called??
Is the same concept for creating dao templates possible for managed beans?
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
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.
I have a large product with many maven projects, all of which can be hierarchically tracked back to the same parent. The projects have javadocs and whatnot.
Icommand line instructions (Windows 7) to generate the full API documents html on my local machine (of all the projects together). If there is a maven command for doing this from the CMD, more the better.
So 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:
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:
I 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?
I 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?
I need to parse an html web page to extract specific information from the tags in Java. For example,
<b>Species </b> Strain </td>
I need to look for the Strain info (Strain is variable in length) in the page. The whole web page is stored as a huge string. I need a regular expression that can identify all the Species and retrieve their corresponding strain info. how to do this or can propose some clever string manipulation methods in Java.
I have a Registration Form in which I am registering user to perform some sort like Entering messages I want to perform some Server Side validation.
Like suppose a user has Enter an Id then as soon as he start entering the Id then I want that this Id should be checked in database that if this Id exists in database or not.
and similar types of validation I want to apply on other fields to.
I have a server written in java and can display html pages. but when i try to add css to the page the server doesnt use it.(not my code). Do you have to flag the browser to use css or something?
public class SimpleWebServer extends Thread { public static final String VERSION = "SimpleWebServer"; public static final Hashtable MIME_TYPES = new Hashtable(); static { String image = "image/"; MIME_TYPES.put(".gif", image + "gif"); MIME_TYPES.put(".jpg", image + "jpeg");
I 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??
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 .
I am working on a little project to create an App that can read contents from a website and return it back to my app. What protocol to use for that. Just the reading/retrieving content from a website.
Is it possible to use java to log on to a website? I mean,Ii know how to connect to a website and send commands, but I am not sure how to tell the server that i want to login?
And then after you logged in is it possible to then do something? like, if you logged in to gmail.com you would be able to see your emails?
