Get variables from jsp
Hi
I have a jsp file that sets som strings and now I wan't to get hold of them from a javabean. Is it possible? I set the strings like this in the jsp file:
String theString = "Hello";
request.setAttribute("theString", theString);To get them from a jsp page i just include the file.
I know it may not be the best way but this is how it is done.
Thanks in advance.
Hi
I'm not quit shore of what you mean but I already have all variables in some jsp files and now I wan't to use them when I output from javabean. This is how I do if I wan't to show "Hello" in a tablecell in jsp:
<td><%=request.getAttribute("theString") %></td>but how is it done if I wan't "Hello" in a string from a javabean like this:
String whatIWant = ????;

How to get variable from javascript to jsp
Hi,
I put a JSP page but in one frame it has a JAVAScript running. The Javascript is a viewer that user can input bounding coordinate and see updated results. Once user input the bounding coordinate in the javascript, I would like to make
that variable available to the entire JSP, so I can submit all query (include the parameter user input in the JSP form) from jsp at a time. How to do this?
Thanks
KennyHi,
Okey here is the code. There are three frames.
1. KennyFrame.htm
2. MapFrame.htm
3. kenny.jsp
Once you run the "KennyFrame.htm" it will show a page
with two top-bottom frames. The top is
"MapFrame.htm".
The bottom is "kenny.jsp"
Once user input something on MapFrame.htm, it will do
a process in Javascript then update the "new answer".
I will need to put that "new answer" into the "What's
mapFrame Input? " Text box. Therefore, when user click
on submit on kenny.jsp frame. The "new answer" will be
submitted.
Code:
MapFrame.htm (the main page)
<body bgcolor="#FFFFFF" text="#000000">
Newmapframe
<center>
<form name=form>
<input type=text name=box value="type in here!">
<input type=button value="Convert"
onClick="javascript:changeCase(this.form.box)">
</form>
</center>
</body>
</html>
MapFrame.htm (the code with javascript on top frame)
<html>
<head>
<title>Map Frame Document</title>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1">
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function changeCase(frmObj) {
var tmpStr;
tmpStr = "Some answer!";
frmObj.value = tmpStr;
// End -->
</script>
</head>
<body bgcolor="#FFFFFF" text="#000000">
Newmapframe
<center>
<form name=form>
<input type=text name=box value="type in here!">
<input type=button value="Convert"
onClick="javascript:changeCase(this.form.box)">
</form>
</center>
</body>
</html>
kenny.jsp (jsp on bottom frame for final submit)
<html>
<head><title>Number Test</title></head>
<body bgcolor="white">
<font size=4>
<form method=get>
What's mapFrame Input? <input type=text name=guess>
<input type=submit value="Submit">
</form>
</font>
</body>
</html>
let us the say the name of the frame in which kenny.jsp is placed be 'kennyframe' and u change the javascript function 'changeCase()' in MapFrame.htm to below:
function changeCase(frmObj)
var tmpStr;
tmpStr = "Some answer!";
frmObj.value = tmpStr;
parent.frames["kennyframe"].document.form.guess.value = frmObj.value; -
Problem accessing session variable from jsp
Hi!
I get an error retrieving a session variable from inside a JSP declaration scriptlet....
Something like this code in a JSP page:
<%!
public void funtion1() {
String parameter1 = session.getAttribute("parameter1");
%>I have seen that I have available getContextServer() method and from there I could call getAttribute("parameter1") . But the thing is that the attribute I want to retrieve was stored in session by another Jsp page.
Any solutions are welcome
Cheers
VictorAppropriately the above is one the reasons also You cannot use JSP implicit objects from the declaration tag. However we can think of a small workaround by passing the reference like the one discussed below
<%!public void funtion1(HttpSession session) {
String parameter1 = session.getAttribute("parameter1").toString();
}%>
<% funtion1(session);%>Hope that helps :)

Getting values from jsp in portlet
Hi,
I want to know if I submit values from a jsp page how can get those values in the portlet class (extends Generic portlet). I have tried accessing using actionRequest.getParameter() and also renderRequest.getParameter(). But I get null value .
Do I need to add the below shown line also to the jsp -
<portlet:defineObjects/>
I am working with JSR 168 portlet. I am posting part of the jsp down let me know how can I go about this problem.
<%@ page language="java"%>
<form name="userForm" method="post">
<table>
<tr>
<td>User Name</td>
<td>
<input type="text" name="userName"/>
</td>
</tr>
<tr>
<td>
<input type="submit" label="Save"/>
</td>
</tr>
</table>
</form>
ThanksHi ,
I created a sample portlet the way it is in notepad portlet and it worked fine for me . But the main difficulty is I am trying to convert an existing code and there the form submission happens in java script .The following code is used to submit the form and there I am not able to get the values in processAction().
Please check the java script code and let me know if I can change it in someway which can make the submitted values available in the processAction().
document.forms[0].action ='<portlet:actionURL><portlet:param name="mode" value="dummyVal"/></portlet:actionURL>';
document.forms[0].submit();

Need help with getting variable from static
Hello,
What I am building is an application that prompts for username/password before it shows the main screen. Once they have successfully logged in, I need to assign the username that they used, in order to use it for a button event if the make any updates.
Here is the code that I have tried to use.
public String username;
///This set's the public variable username
public void setUserName(String UserName){
username = UserName;
/////////////////Here is where they login, and assign the name to setUsername
public static void main(String args[]) throws SQLException {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
JFrame frame = new JFrame();
JTextField userName = new JTextField();
JTextField passWord = new JTextField();
Object[] options = {"OK","CANCEL"};
Object[] msg = {"UserName:", userName, "Password:", passWord};
final JOptionPane op = new JOptionPane(msg, JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION){};
JDialog dialog = op.createDialog(frame, "Please Login");
dialog.show();

I am trying to set the public username variable to what the person enters, however since I am creating a seperate instance of it, I don't believe it will work. Any help would be very much appreciated.
Thanks.
JoshI am developing in Netbeans. If I try to remove the static keyword from main(), netbeans canno't find a main to run. I have created the User class.
Here is the main again to show what I have done.

java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
User user = new User();
JFrame frame = new JFrame();

try {
result = ((Integer)op.getValue()).intValue();
}catch(Exception uninitializedValue){}
if(result == JOptionPane.OK_OPTION) {

user.setPassword(passID);
if(!userID.equals("") && !passID.equals("")) {
//Auth.setUserName(userID);
//Auth.setPassword(passID);
new Main().setVisible(true);
}else {
// user cancelled
This set's the variables

String User = user.getName();
System.out.println(User);
String Manager_info[] = {"managerindex", "managers", "managername"};

SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yy");
String today = formatter.format(myDate);
String [] str = {
"EmpID", "Account", "System", "Type", "Status", "UserID", "Group"
This gives me a null on the println, how can I get the data that was entered in main()?

Reading Variable from JSP and pass to servlet
hello
i have a servlet page which transfers data to a jsp page. The jsp displays the data only. Now i want to read a string from a jsp page and then pass it to the servlet.
How can i do it?
thnkshello
this is working fine: out.println("<input
type=\"hidden\" name=\"bookId\" value=\"+bookId+\"
size=\"25\">") ;
works fine
thnksI guess you didn't understand me. Look to the difference between the following two statements:
out.println("<input type=\"hidden\" name=\"bookId\" value=\"+bookId+\" size=\"25\">") ;and
out.println("<input type=\"hidden\" name=\"bookId\" value=\""+bookId+"\" size=\"25\">") ;In the first you're handling the bookId variable as String, in the second it will use the actual value of bookId. -

}Edited by: Djanym on Mar 16, 2009 4:43 PMThis is a classic problem that coders run into when trying to get their head around object-oriented programing. Since you have a class that should be modeled after a real world object, as far as that object is concerned, no one else needs to know the details of it - without asking nicely. This is where you should set up some getters and setters, which are methods that allow fields in a class to reveal themselves or allow their states to be changed in a orderly fashion.
There are a number of fields that never need to be known outside of the class. Then there are some fields you would like to let people know about, but don't want them to have the ability to change them. In the example below, there are to getter methods allow return of the necessary fields. If you made these public, there is a possibility that someone utilizing this field may change it outside of its intended use, or access them without them being ready for public consumption.
Class test {
//These private variables are only visible from the class
private int grade1 = 0;
private int grade2 = 0;
private int grade3 = 0;
private float average = 0;
private int gradeboost = 0;
//This method sets the gradeboost field to one desired by the instructor
void setboost(int boost) {
gradeboost = boost;
//These methods accept test scores and compute the average for three test
//Notice that the calculated average may not be the true average of the three test scores
//because of the possibility of gradeboost calculation being greater than 1
void test1(int score) {
grade1 = score;
average = (grade1 + grade2 + grade3 + gradeboost)/3;
void test2(int score) {
grade2 = score;
average = (grade1 + grade2 + grade3 + gradeboost)/3;
void test3(int score) {
grade3 = score;
average = (grade1 + grade2 + grade3 + gradeboost)/3;
//This is a getter method, which provides read access to the private variable average
//If someone just had public access to the grades and wanted to take their own average
//They would miss how the gradeboost field affects the final outcome.
float getAverage() {
return average;
//Here is a getter method, which accepts an argument to determine which test score to return
//Notice that this isn't the true testscore, but it has been modified by the gradeboost field.
//If the user had public access to the true testscore, it wouldn't take into account the gradeboost calculation!!
//This is how a getter can control exactly what a user has access to.
float get testScore(int test) {
float testresult = 0;
if (test = 1) {
testresult = (grade1+ gradeboost) / 3;
if (test = 2) {
testresult = (grade2+ gradeboost) / 3;
if (test = 3) {
testresult = (grade3+ gradeboost) / 3;
return testresult;

Can I do that ?
Nothing I came up with worked, and I found nothing on the Internet. I searched for a lot of things. Is the only way to just implement that JSP page as a servlet ?
Please see code below
thank you !!
Dennis
<sql:setDataSource var="profileDS"
url="jdbc:mysql://localhost/test"
driver="com.mysql.jdbc.Driver"
user="xxx" password="xxx" />
<sql:query var="profileQuery" dataSource="${profileDS}">
SELECT likes
FROM profiles where likes=?
<sql:param value="${param.likes}"/>
</sql:query>
<c:forEach var="item" items="${profileQuery.rows}">
c:out value="${item.likes}"/>
<%
String dd= request.getAttribute("item.likes");
out.write(dd); //does not work here ... should print out the value of item.likes
%>
</c:forEach>Some funny scooping with forEach. But if you put a "<c:set var="item.likes" value="${item.likes}" scope="request"/>" first inside the loop it is possible to use that value for your script. But using your sample the printout gets funny. All script output first and then the EL-created out.
Hopes this helps you anyway.

Passing variables from JSP to XSL
Hi;
I need to pass some variables with string value in them to an xsl page to store them in a <param..> tag... ive so far been unsuccessful at that, the following are my codes.. : Does anyone know how to pass it directly into the xsl page ?...
jsp page :
<%
String compNames;
String[] listRight;
compNames = (String)session.getAttribute("compNames");
listRight = request.getParameterValues("listRight");
String yr1 = listRight[0];
String yr2 = listRight[1];
String yr3 = listRight[2];
String yr4 = listRight[3];
String yr5 = listRight[4];
pageContext.setAttribute("yr1", yr1);
pageContext.setAttribute("yr2", yr2);
pageContext.setAttribute("yr3", yr3);
pageContext.setAttribute("yr4", yr4);
pageContext.setAttribute("yr5", yr5);
pageContext.setAttribute("compN", compNames);
%>
xsl page :
<xsl:param name="CoCode"><core:param name="compN" value="${compN}"/></xsl:param>
<xsl:param name="yr1"><core:param name="yr1" value="${yr1}"/></xsl:param>
<xsl:param name="yr2"><core:param name="yr2" value="${yr2}"/></xsl:param>
<xsl:param name="yr3"><core:param name="yr3" value="${yr3}"/></xsl:param>
<xsl:param name="yr4"><core:param name="yr4" value="${yr4}"/></xsl:param>
<xsl:param name="yr5"><core:param name="yr5" value="${yr5}"/></xsl:param>and to display the xsl, ive used to following Include code :
<jsp:include page ="./ratios.xsl"></jsp:include>
