Reload / Refresh JSP without using parameters

Hi,
I have a servlet, which gets data from a mobile phone and puts the data into a database.
Then I have a Java Beans that takes data from the database. But I dont pass it with the
request and response parameters.
I just use the data like you see below, I use the object of the Java Beans mybean. In
its constructor I do all the stuffs to read data from database.
<jsp:useBean     id   = "mybean"   scope    = "session" class = "org.myHalloGMap.handler.Handler" />
<jsp:setProperty name = "mybean"   property = "*" />The data I use like this:
<%
     for(int i=0;i<mybean.row_count_coordinates;i++){
              if(mybean.getUsrn().equals(mybean.coordArrUsername)){
row_count++;
So my problem is now:
How can I refresh my jsp, so that I can display the data, i read out of my database?
When I use the webapplication and put new data into the database, on my webapplication
is still shown without the new data. When I refresh the browser, it still shows me without
new data?
Can someone help me?

Perhaps the bean should be set to the request scope, since you use the constructor to read all the data from the database. When you use the:
<jsp:useBean id = "mybean" scope = "session" class = "org.myHalloGMap.handler.Handler" />You will only create a mybean instance if one doesn't exist. When you first visit to the page the session is new, so you will create the mybean instance. After that, the mybean instance is found in the session so a new one isn't made - which means the constructor isn't called, which means no new data is read.
If you put it in the request scope then the mybean instance will be re-made each request.

Reload a jsp without using javascript

I need to reload a jsp based on some jsp condition. I know that I can't do something like below:
<% if (reloadCondition == true) { %>
<script language="JavaScript">
document.location.reload()
</script>
<% } %>
Any suggestions?

You can redirect the page to the same.
Some thing like :
<% if (reloadCondition == true)
response.sendRedirect("same.jsp");
return;
%>

How to execute a .exe file in java(Jsp) without using a process ???

Hi All ,
How to execute a .exe file in Jsp without using a process ??? ...
Is it Possiable ????

But as this a web application ... By using Runtime i'm getting some probs ..
Let me guess, you want your web application to run a program on the client and to your surprise that's not working?
Ain't gonna happen.
its taking more time to execute .... that's y is there any other option to execute .exe file other than Runtime.getRuntime().exec("filename");Write proper English and you may be taken more seriously.
1) it's not "taking more time to execute", whatever that's supposed to mean.
2) there's no other way to execute something. Not that you should every use even that way anyway
3) whenever you start thinking of executing external programs from Java, start thinking of not using Java in the first place.

Data fetch from table without Refresh and without using tab key.

hi Friends,
I have a problem i want to extract data from table without Refresh into text field without using Tab key. when i'll enter any value in a text field then corressponding value should come in to corressponding textfield without using Tab Key.
eg. when i enter emp_id 101 in a text field then the first_name and last_name ,adress should come in to corressponding text fields without refresh and without using Tab key.
How Can I do this.
Thanks
Manoj

Hi Manoj,
I assume that this is similar to: Data fetch without Refresh rather than Re: Value of one textfield should come into another textfield Without Using TAB ?
If so, the only change you need to make on the first one is to use "onkeyup" instead of "onchange" in the item's "HTML Form Element Attributes" setting.
Note, however, that the user must move away from the item at some point (for example, to click a button), so the onchange will be triggered anyway.

Including Applets in jsp without using Archive

Can any one help me to include the Applet without using the Archive attribute in either <jsp:plugin> or <applet> tag. I am using WebLogic workshop8.1 on win 200 platform , it builds class files in a seperate directory which starts with .workshop dirctory. I should include that directory as the codebase for the applet.

yeah. don't use it. You specify the code (class) and the codebase tag, and the classes have to be loose on the server under the package directory structure that the classes' package is set up for.

Get context path in a jsp without using a scriptlet

${pageContext.request.contextPath}A common practice is to put this value in the <base href> in the HTML head and then use this as the root for all of the relative URL's in the page.

How to iterate List in jsp without using for loop

Hi,
I am developing a small application is struts. I have one ActionForm file which contain one List like getEmployeeDetailsList(). When I am using this list in jsp page for displaying data. I want to display it as employee name, employee address, employee designation and employee contact no. These all fields are available in the above list. Now what is the problem is that I am using logic:iterate method to iterate data. but this is not sufficient to display all records in order. like employee name should be in one table and they can be vertical not horizontal, employee address is also should be seperate. and same thing with employee designation and contact no. I don't want to use for loop to iterate this list. Please tell me about optionCollection for this list. only employee names should be one drop down and employee designation is also in another drop down.
Please help. It is really urgent.
Any help will be appreciated.
Thanks in advance.
Manveer

I'm not sure what you problem is, but one thing you can do is to create a new class and pass the list into its constructor (and store it as a private variable). Then, provide a set of functions in the new class that extracts data from the list and returns it in a form that the various parts of the JSP page wants. For example, one function may return a sorted list of just the employee names. In this way, all the business logic for formatting the data into a form that JSP page likes is hidden inside the new class.

I have one included page in one jsp page(mother page). I have included it by jsp:include tag. The included page consists of two inputText. I need to pass the parameters of the mother page together with the parameters in the included page in the backingBean of the mother page. Hope this one is clearer.
The code snippet in the mother page looks like this
<jsp:include page="/pages/ps/sample_rep2.jsp"/>.
In the sample_rep2.jsp, I have two inputText. How can I pass this in the backingBean of the motherpage.
The sample_rep2.jsp is the included page here. The sample_rep2.jsp looks like this:

Getting absolute path of a file in a webapp without using servlet/JSP

Hi all,
I need a small clarification. Is it possible to reterive the absolute path of a file present in a tomcat web application without using Servlet/JSP. I have a normal java class which uses this file to read the configuration parameters. I like to know whether I need to create a seperate servlet which will read the parameters from web.xml.

Hi all,

whether I need to create a seperate servlet which

Passing javascript values to jsp without refreshing the page

Hi,
How do u pass a value of a javascript variable to the jsp without refreshing the page ?
For example, a file called test.jsp in which a javascript variable x contains value 254. I need to pass the value of x to a method declared in test.jsp(same page).

Hi Mona,
when i say refresh i do mean a blink of the browser.
This is a small example i wrote to show you how you can pass javascript varables to JSP variables. If you don't want the refresh to be seen by the user just include this code in a hidden frame on a page and instead of refreshing the entire page, refresh the hidden frame.
i have to say, i didn't test the code so i don't guarantee it's flawless.
if you need an more detailed example just tell me, i'll create one, but it won't be for today :)
<html>
<head>
<title>Log in to the system</title>
</head>
<body>
<script>
//we retrieve the parameter 'user' from the URL
<%
String username = request.getParameter("user");
%>
var user = "<%= username%>";
//check if there is a username in the URL
if(user=="null")
//there is no username so we log the person in as a guest
user="guest";
//we refresh the page and set the user parameter to 'guest'
//the parameter now contains the javascript variable 'user'.
//The parameter can be read by the JSP (see the top op this script).
//This way we gave the javascript variabele to the JSP variable
location="login.jsp?user="+user;
else if(user=="guest")
{ alert("Welcome "+user+", I hope you like this site"); }
else
{ alert("Welcome "+user+", I'm glad to see you again"); }
</script>
</body>
</html>

Forward to JSP page without using Navigation Model

How can I forward to a JSP page without using the Navigation Model?

It's done in the cardemo example in
ImageMapEventHandler.processAction() Is there a reason
for it there?Ah ... that makes sense.
That code in CarDemo was written before there was such a thing as a NavigationHandler, and we didn't have time to update it to the new approach before the EA4 release. That'll be changed before the next one. In the mean time, I'd recommend that you use the navigation rules mechanism where it works for you, because it encourages good separation of business logic and presentation logic that will lead to more maintainable applications.
