I am creating a webapp project , in which i have loaded my JSP page having JSTL tags in a DIV tag successfully but when user clicks on a radio button a jquery fires which loads that perticular div tag , and the html content in that div tag is then loaded again but not the JSTL content..
View RepliesI am using Jboss as application server and tomcat as web server.
How to turn off auto-reloading of servlets and jsps.
Since I done a recent git pull on my project, for some reason now Im getting an error when starting Tomcat and rendering the index.jsp, but I dont understand whats changed, as this was working before.
The error:
org.apache.jasper.JasperException: /index.jsp (line: 4, column: 42) File "/blog.postTags" not found
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:42)

org.apache.jasper.compiler.Parser.parseDirective(Parser.java:475)
org.apache.jasper.compiler.Parser.parseElements(Parser.java:1427)
The index.jsp:
<!DOCTYPE html>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="p" uri="blog.postTags" %>
<html>
<head><title>Blog Home</title></head>
<body>
<h1>Blog Home</h1>
<br />
<% out.println("Your IP address is " + request.getRemoteAddr()); %>
[code]....
I really am unsure as to why this has stopped working, I even rolled back to an earlier commit and this was definitely working before, but I havent changed anything, Initially when you start Tomcat is shows another error in the browser, but on a refresh its a null on this tag library?
I would like to know why javax.faces.webapp.FacesServlet

View Replies View RelatedI am creating a shopping list, with each element and object called product from the Item attribute class. Each product object has a description, price, and priority. From user input, I am able to create each product object, and then .add to my arraylist. I know that it successfully adds because I have it printed in each iteration of the do-while loop. Once the user indicates they want to quit, the loop ends. I then want to print each description, price, and quantity but this for loop will only print the last element over and over. Here is what I have:
ArrayList <ItemAttribute> list = new ArrayList<ItemAttribute>();
Scanner keyboard = new Scanner(System.in);
ItemAttribute product = new ItemAttribute();
public void findDescrPrice() {

I have one Project -"A".Inside of that I use, .XLS to read data.
Structure - A/src/TestData
Inside of the TesetData - I have placed XLS files.
I have main method in TestDriver class.If I run this in Eclipse, running fine.But after exported to executable/runnable Jar, and ran via command line (command - jar -jar myjar.jar), I see issue: "Exception in thread "main" java.io.FileNotFoundException: srcTestDataTestCaseController.xls"
public static void main(String[] args)
throws Exception
{
ResultSet rs;
rs = readExcelData(testControllerName, sheetName, "");
}
As I use main() method which is static, I am getting error if I write like the below:
public void getXls(){
String testControllerName ="TestCaseController.xls"
TestDriver.getClass().getClassLoader().getResource (testControllerName);
}
How to read/access the XLS, after I exported as runnable jar
We have a webservices application that uses Java 1.6.0_43, Spring 3.2.3, CXF 2.6.9 and deployed to Jboss 5.0.1 GA in a LINUX x86_64 centos box. It essentially uses apache httpclient (4.2.2) to call internal services and returns the results back to customers. The application has been running fine for a year or so until early this month when all of sudden, it loaded about 300K classes in a very short time during our regression tests and saturated the CPU usage ever since. Hence the application is no longer responding.
I have been trying to troubleshoot the problem for a while. Tried visualvm, dynatrace. thread dumps. heap dumps... None of them is very effective in capturing what are the classes that are loaded so many times and what path triggered that.
One of my friend asked me that which will load first static variable or static block ? My answer was to static variable.. So he gave me two program and said to differentiate between them
1st program
public class Test {
public static void main(String args[])
{
System.out.println(Test.x);
}
static {
System.out.println(Test.x);
[Code] ....
Output of this :
90
90
I tried to decompile the byte code and found it's same for both the above equation. How to differentiate between them. I am confused when the static variable will initialised.
I am fetching records from result set and displaying on JSP with <c:forEach> tag
<c:forEach var="outer" items='${ProductList}' varStatus="seq1">
<tr>
<td class='center' nowrap><input type="radio" name="view" id = "view" value="Y" ></td>
<td class='left' nowrap><c:out value='${outer.sourceIndex}' /></td>
<td class='left' nowrap><c:out value='${outer.prodNameAbbr}' /></td>
<td class='left' nowrap><c:out value='${outer.productName}' /></td>
<td class='left' nowrap><c:out value='${outer.effectiveDate}' /></td>
<td class='left' nowrap><c:out value='${outer.uuName}' /></td>
</tr>
</c:forEach>
Below is one row with radio button
SourceIndex ProductAbbreviation Product Name Effective Date UseID
ABC PQR Test123 03/12/2014 smj
I have a view button also to select above radio button. When I select that I need all above values to be set in request.
translate this part to jstl and el?
<%
while(i<nrows){
if(i==0){
%>

I am looking at JSP page, which has code line as follows
<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %>
This taglib will have to be installed on local environment. How is it referred in jsp ? I dont see any code in jsp, which refers to the location of JSTL. So how does jsp invoke these tags ? Is it through classpath ?If its so , how is classpath set for JSTL ? Is it just as classpath is set for java ?
i am doing a code using JSTL to fire a query. everything come fine except the resule is not sorted as desired. i am putting the code below--
String sort_order=(String)request.getAttribute("sort_order");
request.setAttribute("sort_order",sort_order);
<sql:query var="viewQueryj" sql= "select USER_ID, PERMISSION_ID, USER_NAME from administrator order by ?">
<sql:param value="${sort_order}"/>
</sql:query>
now the resule is always sorted by USER_ID. if i want to sort it using USER_NAME i pass parameter from controller to this page in sort_oredr variable which comes fine but the result doesn't sort by name, only by id. if i hardcode USER_NAME in query then the result is as desired.
I want to use the list element inside my scriptlet. Below is my code which is not working.
<c:forEach var="social" items="${sociallist}">
<%
callToFunction(%>${social}<%);
%>
</c:forEach>
How can i access social var inside scriptlet.
In JSP page: firstly set the setter of a entity in bean and then set it in session,request etc. and gvet values using foreach loop as follow :
<jsp:useBean id="st" class="beans.student">
<jsp:setProperty name="st" property="roll_no"/>
</jsp:useBean>
<%
[Code]....
Here start is the variable whose value will vary after every time i visit this function.So how would i be able to use above query.
P.S. i was using scriplet before and i was able to deal these issues with scriplet easily.
I have the following data in a file called books.xml in my WEB-INF folder:
<?xml version="1.0"?>
<books>
<book>
<name>Padam History</name>
[Code] ....
I'm using the following code in a jsp:
<c:import var="bookInfo" url="/WEB-INF/books.xml" />
I know that it's finding the file because if I delete books.xml from the WEB-INF folder I get a FileNotFound exception.
However, for some reason it doesn't appear to be importing the data into the bookInfo variable.
I noticed this problem because when I try to parse it via:
<x:parse xml="${bookInfo}" var="output"/>
I get org.xml.sax.SAXParseException: Premature end of file.
When I try to display the data in the variable either by:
<c:out value="${bookInfo}" />
...or by means of a scriptlet (which I realize is not a best practice):
<%
String myVariable = (String)pageContext.getAttribute("bookInfo");
System.out.print("bookInfo=" + myVariable);
%>
...I get nothing.
BTW when I do:
<c:import var="data" url="http://www.tutorialspoint.com"/>
<c:out value="${data}"/>
that works fine!
I have a HashMap returned from the server. There are two conditions
1. HashMap returned with only one set of key value pair or
2. HashMap with multiple set of data key value pairs.
Now in UI I have to display either text box or drop down box depending upon the size of map for that I am using length method
Java Code:
<c:choose>
<c:when test="${fn:length(myDto.mayMapInDto) eq 1}">
display text box
</c:when>
<c:otherwise>
display drop box
</c:otherwise>
</c:choose> mh_sh_highlight_all('java');
I can display drop box by looping but not sure how I can get only one element for text box. Tricky is I can't use key value to access since UI don't know what key will be returned.
I have for values in drop down:
<SELECT name = "productCodeDefault" id="productCodeDefault" value="<c:out value ='${ProductDefBean.productCodeDefault}'/>" >
<OPTION value="" ></OPTION>
<OPTION value="a" >A1</OPTION>
<OPTION value="b" >B1</OPTION>
<OPTION value="c" >C1</OPTION>
<OPTION value="d" >D1</OPTION>
</SELECT>
When I am getting value = "a" from ProductDefBean, In the dropdown 'A1' should get selected. This is not happening. What I need to modify?
Note** When I am doing view Source of my JSP, I am getting value='a'
Is there a way we can open a .chm file stored at server through jsp application without downloading the file and saving it to the local machine.
What I googled is : we cannot download .chm files from a web browser and simply click Open. Download the .chm file to your computer first, right-mouse click it in Windows Explorer and select Properties. Then click Unblock.
But I want my users to simply view the file without downloading it.
In jsp when using EL the parenthesis are not allowed for grouping of expressions. I mean
${(2+3)-1}
is not allowed so if i have to group expressions in EL how do i achieve it?
I wanted to do the following in EL
${(a==b && b==c) || (v==r && r==d)}
so how do i achieve this?
Why will this NOT validate correctly in my IF Statement? Basically, a user chooses an option from the drop down list. The value is passed to t.jsp (itself) and if the option "All" is chosen, then it does something. If any of the years are chosen, then it does something else.
t.jsp (simplified version of what I want)
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<html>
<form method="get" action="t.jsp">

One of my official site is not disaplying the content in machine#1 IE10 browser.And the same site is showing data in another machine#2. I compared the both machines JRE and JDK settings but no difference found.
how to link the JRE to browser.
I'm a first timer at jsf, and right now I'm learning how to use ajax in jsf. i got a problem when i click a command link i want to change in a content, but when i run my web and i click the command link it didn't do anything. This is the source :
<?xml version="1.0" encoding="UTF-8"?>

In this code when i click the Home button it suppose to change the ouput text to a string that store in my bean. This is my bean:
/*

* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package UI;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

At first the output text value is the same as the string i store in the bean. but when i click the commandlink, it didn't do anything, is there something wrong with my code?
