My jsp page needs to have a dropdown box. on selecting one/more than one values from this list, the same values get populated in another one.. we have a delete button too , it allows to populate the second box again.
The thing is i am to avoid scripts and use custom tags as much as i can...
Is there anything wrong with writing JSP tags in psuedo-HTML? I've been writing tags in XHTML, but it would seem that XHTML could not be compliant with both an XHTML standard and the HTML5 standard.
<esi:assign name="searchfor">'''someval like < or >'''</esi:assign> . Now on the basic of request param i want these tags should render with value < or > on the basis of what is inside tags. I applied the below code but didn't work. Any Idea. <c:if test="${testval}" > <jsp:text><![CDATA[<xmp>]]></jsp:text> </c:if> <esi:assign name="searchfor">'''>'''</esi:assign> <c:if test="${testval}" > <jsp:text><![CDATA[</xmp>]]></jsp:text> </c:if>
how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.
I am trying to write the id3 tags using mp3agic library. The problem is it does not update the id3 tags for the mp3 files which already contains id3 tags but it only updates the file that have id3 tags which are empty.
When i look at the newly created files, they contains the older tags. Then i wrote a script to access id3 tags through mp3agic
id3v1Tag.getArtist()
then it was showing updated tags.
Why it is showing updated tags even if they are not really updated in folder where i visits ?
I am familiar with php, but I don't know Java. We need a program, that will be able to scrape large amount of title tags from large sites, fast. I've been trying Seo Spider by Screaming Frog, and Xenu's Link Sleuth, but these programs are not good enough. They hang up, they save all the data in RAM, I think, and after a relatively short period of scraping, they stop working, become unresponsive, and so on.
Somebody recommended me getting a custom made program in Java, which would be able to scrape title tags only, from large sites (I am talking 25 - 50 million pages or more). I was told that it would not have a graphic interface, or anything like that. Nothing like this is needed too, we just need to have title tags.
1. All jsf tags like datatable, form, etc.. will generate UIComponents in server side, right?
2. All non JSF tags will not generate UIComponents in server side, right?
3. If you want something in a view that will be the same across users and requests, I mean, It will not change like a label tag, it doesn't make any sense to create it with a JSF tag in order to save memory in server side, right?
I know that the simple deployment using only applet tags inside HTML causes severe security restriction for the applet on the client side. but can this simple HTML file contains .jar files inside the applet tags instead of .class files.
I want to create a quiz in java in which questions and options will be retrieved from mysql database.I want the options to be in drop down list format.And I am using jsp for presentation layer and all the connections with database are in java..how to retrieve the options from database to drop down menu...

I am familiar with Java but new to JSP. I have a Java Servlet app where user actions are recorded in a SQL Server database amd I now need to quickly put together a JSP front end application to view user actions. I want two drop down boxes to filter the results that will be displayed in a list box. What I need is the first drop down list box to show unique user names that have logged in. I can interrogate the database with the following SQL;
"SELECT DISTINCT(USER_ID) FROM AUDIT_MESSAGE"
Then when a user is selected from the first drop down list box (perhaps some sort of on change event) a second drop down list box shows the logins times of the selected user. Again I can interrogate the database with the following SQL;
SELECT SESSION_ID, EventTIME FROM dbo.AUDIT_MESSAGE WHERE OPERATION = 'loginResponse' AND RESULTS = 'OK' AND USER_ID = 'firstdropdownlistselection'
Then finally when a login time is selected in the second drop down list box all events for the selected user while logged in with that login time are displayed in the list box.
I have a jsf form which has a drop down. When I select any value in drop down it shows related details. When I use chrome browser, and I press back space key it comes back to the page, it keeps the value selected which was selected earlier, but in the firefox, IE it keeps the zero index selected. The same code is not working for chrome browser.
I would like the zero index to be selected in the drop down in previous page in chrome browser also when back space key is pressed...
i am trying to create an applet with drop-down lists. When I compile the program the following error message appears '. . .is not abstract and doesn't override abstract method action Performed. . . Here is my code . . .
import java.awt.*; import java.awt.event.*; import java.applet.*; public class DavidApplet extends Applet implements ActionListener //class header { Label fName=new Label("First Name");
I have a fixed list of 20+ values to be populated in a dropdown. The set of values are always going to remain the same, no future scope of modifications, additions or deletions.
Listing each of them as <option> in JSP is making the page look cluttered. Or is it better reading it as a comma-separated string from a properties file and then iterating to populate the dropdown.
What will be the best approach to populate such a dropdown in JSP?
Is it possible to get the list/ values in html/jsp from servlet?
I have a table inside an html/jsp page and when the user clicks a button I need to refresh the whole page with some additional text message.
Currently what I am doing is that I am using a java bean for the jsp page that contains a list of values inside the table then store it in session but I think there is a better way without storing it in session.
I tried using request.getParameter() but it only returns string.
I have list of employees in my database and their associated information like employeeId,supervisor and process. I have class named EmployeeDetails having same properties. I am fetching details of all users using below code:
In employeeList, we have list of objects having data of employees. I donot know how to get which object is selected in dropdown and based on that rest of the text fields are populated. Example:
Name ID Supervisor ------------------------------------------------------- Pawan Kumar3033045Vimal Kumar Vimal Kumar3040901Dinesh Hemrajani
If Pawan Kumar is selected from dropdown then '3033045' and 'Vimal Kumar' should get populated.
My question is related to combo boxes. A combo box in general is a text field with a dropdown list. I would want to know if we can replace hthe dropdown List by an other component, for example a JTable component.
I am working on a project that uses a custom tag in a JSP file. Here is the tag descriptor
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd"> <taglib> <tlibversion>1.0.0</tlibversion> <jspversion>1.1</jspversion>
[code]...
Everything seems working fine except that the custom tag handler does not get called at call. I set breakpoint and it never stops there. The JSP page is displayed fine, only not showing the custom tag content and there is no logged error/warning from the log. The tld is found fine. Like what classes called/validated the tag handler so I can logging those classes at DEBUG level to see what goes wrong.
I would like to create a custom tag which works similar to <c:forEach/> tag i.e
<c:forEach var = "movie" items = "${collection}> ${movie} </c:forEach>
I would want to create the similar behaviour(as above) in my own custom Tag.Morever I would like to use the doStartTag() and doEndTag() and doAfterBody() methods while creating custom Tag.
