I have two jsp pages. I am trying to add "Russian" language. Russian characters are shown perfectly on jsp page, but when I try to send this value to another jsp page from parameter then in second jsp page this value is changed to different characters. This problem is only in Russian Language and not in others such as Italy and French.
For example
On demo.jsp page the russian character "приветствие" is shown correctly.
but when I try to send it to another page "test.jsp" then some unknown
characters are shown like "!C<Cä5 Cô>CôCC´OD=Cä5!"
Code:
demo.jsp
String welcometext=langP.get("welcome");
<jsp:include page="<%=test.jsp%>">
<jsp:param name="wlc" value="<%=Encode.hex8Code(welcometext)%>" />
</jsp:include>
In test.jsp
String title = Encode.utfToUnicode(Decode.hex8Decode(request.getParameter("wlc")));
System.out.println(" Russial welcome test "+welcome);
Is there any special code we need to add for Russia while sending them in query parameters??
Please note* the following code are already written else it would have given problem for French and Italy language too..
<%# page contentType="text/html; charset=UTF-8" %>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
Also tried with following but didn't help out!
request.setCharacterEncoding("UTF-8")
Try to add <% request.setCharacterEncoding("UTF-8"); %> to your main jsp page:
Here is my example:
demo.jsp
<%#page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<% request.setCharacterEncoding("UTF-8"); %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>Привет</h1>
<jsp:include page="/test.jsp" flush="true">
<jsp:param name="wlc" value="Привет"/>
</jsp:include>
</body>
</html>
test.jsp
<h1>Param values is</h1>
<%
String hello = request.getParameter("wlc");
out.print(hello);
%>
I don't know the better solution but the following code solved this issue. I kept the variable in session attribute.
demo.jsp
session.setAttribute("welcometext", welcometext);
test.jsp
String welcometest=(String) session.getAttribute("welcometext");

I wrote a servlet.
request.setAttribute("itemCount", 1000);
request.getRequestDispatcher("test.jsp").forward(request, response);
And in test.jsp I wrote:
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<%
String name=(String)session.getAttribute("itemCount");
out.print("Total items are: "+name);
%>
<p>Number of items: ${itemCount} </p>
</body>
</html>
But the second row is
Number of items: 1000
while the first row is
Total items are null
So what's the issue?Any help? Thx.
In your servlet, you can try using:
request.getSession().setAttribute("itemCount", 1000);
& then in your jsp, you can access itemCount the way you are accessing.
Or alternatively,
use
<%
String name=(String)request.getAttribute("itemCount");
in your jsp if you don't want to change any code in servlet (also mentioned by tgdavies in comment)
I want to send a query string from one jsp page to jsp page but I want to hide the name-value pairs(attributes) at address bar when I send the query string.

Here, I pass a query string "Second.jsp?username=aditya123&password=abc12345" from First.jsp page to Second.jsp page but I want to send this without showing username and password attribute and their value at address bar.How can it possible?
Try this code
<form action="some.jsp" method="post">
<input type="text" name="uid" >
<input type="password" name="pass">
<input type="submit" name="login" >
</form>
Adding method ="post" hides the query stringThat is ,if i remove ' method="post" ' the processed url on pressing submit button would be having
Following as query string
uid="whatever i wrote in text field"&pass=""&login="Submit"
But after writing ' method="post" ' the new url will be free of query string...!
it is not possible with link.
alternate solution of not showing attribute is encode that name value pair and send it with url and decode at another page.
use either url encoder given by java or make use of your own encrypt-decrypt method.
The easiest thing to do is <form action="some.jsp" method="post">
Do this formatting in the html code.
And contents of url will be hidden...
You can store all the objects/information you want to pass to the second jsp file by storing the objects in the 'session' implicit object using session.setAttribute() method. In the second page you can retrieve those objects from the 'session' object using session.getAttribute(). My assumption here is that both the jsp pages are being executed in the same HttpSession, hence the same 'session' object will be available to both the jsp pages.

I have a facultylist.jsp page which displays List<Faculty> as a request attribute parameter in forEach loop and I want every item in this loop to be a link to specified faculty facultyview.jsp. How can I achieve that ?

I don't know if its may help, but I'm using following technologies: tomcat, jsp, servlets and log4j.In my project I have one FrontController, which is a servlet that interacts with Command pattern - each Command returns a path to resource and action type: forward or redirect.
You can solve your issue by adding a query params to the link, edit with respect to the comment. Note that you cannot access directly the JSP pages that reside under WEB-INF folder. Also, to encode properly the paramters, better construct url like
<c:url value="facultyview.jsp" var="url">
<c:param name="name" value="${faculty.name}"/>
<c:param name="total_seats" value="${faculty.total_seats}"/>
<c:param name="budget_seats" value="${faculty.budget_seats}"/>
</c:url>
<li>${faculty.name}</li>
and than than in your facultyview.jsp read from the query params
<li>Faculty name: ${param.name}</li>
<li>Total seats: ${param.total_seats}</li>
<li>Budget seats:${param.budget_seats}</li>
This direct JSP communication should solve your immediate issue, but a truly proper way would be to pass an id of a faculty to servlet, fetch the faculty instance, place in the model and pass to the view.
in other way is just take the selected value from the drop down with a name and forward it to front controller servlet ,there use if else conditions and depends on the value you could forward the request to corresponding jsp or servlet
<select name="value"> in jsp
String value=req.getParameter("value"); in servlet
if()
else if()
If you have a field in Faculty entity simply:
${faculty.name}
#Mark: faculty represents an entity from database, i'm not sure if I want to change it adding another field, or you mean some other way ?
Add a field does not means you must change database, you can have a Helper entity that inherits from Faculty and have more fields you can need,
public class FacultyFormHelper extends Faculty implements Serializable {
private String URL;
and in your view:
${facultyHelper.name}
But, If you don't want to modify your database, either create a helper class, you may add onclick event to the <a>
<a onclick="goToURL(${faculty.id})">
Then retrieve the data... i'm not sure how you get the urls... from a variable in the view, ajax call or wherever you have this URL...
i try to get the information of a user on my database, store the object in a session then show the session's contents on a JSP page. Whenever I try to show it on my page, the content of the session does not appear. Please help.
THIS IS THE JSP PAGE I WAS TALKING ABOUT:
<%#page import="neospa.Client"%>
<%#page import="DAOs.ClientDAO"%>
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>

<title>CLIENT INFORMATION</title>
</head>
<body>
<h1>CLIENT INFORMATION</h1>
<br>
<%Client client = (Client)session.getAttribute("Client");%>
First Name <% client.getFname(); %> Last Name <% client.getLname();%>
<br>
Birthday <%client.getBirthday();%>
<br>
Home Number <%client.getHomeno();%>
<br>
Mobile Number <%client.getMobileno();%>
<br>
Office Number <%client.getOfficeno();%>

Email Address <%client.getEmail();%>
<br>
Address: <%client.getAddress();%>,<%client.getCity();%>,<%client.getRegion();%>,<%client.getCountry();%>

Is there something missing here that I need to put? :)
in netbeans 7 and jdk 7 and everything is working fine without any changes i made in my environment the old tags are working fine of jstl ${class.get_name()}
${page.getTitle()}
the new once i introduce does not work, and i don't know why ?
see this simple application example i created added jstl 1.2 into the libraries
and still it does not work?
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>Hello World!</h1>
<%
String var1;
var1 = "Welcome";
%>
normal : <%=var1%>
<hr />
dollar: ${var1}
</body>
</html>
First of all, the above page doesn't even use the JSTL. It uses the JSP EL.
And I assume you expect to see dollar: "Welcome" printed, but that won't happen, because the JSP EL doesn't print values of local variables. It prints the value of attributes.
Change your code to
<% pageContext.setAttribute("var1", "Welcome"); %>
or, better, to
<c:set var="var1" value="Welcome"/>
and you'll see the expected output.
