Get dynamic values in Jsp fom Applet
Hi,
Mine is not a unique question, its been asked many times on the same forum but still I havent got any satisfactory answer so I am putting this again.
I have one applet, it is been loaded from jsp. Applet uses double buffering and its values are changing constantly.
Now my question arises here, In my jsp i have one button on the click of that button I am calling some other jsp passing some of jsp values in URL. I also want to pass one of the value of applet to jsp so it can pass to next jsp or to do something that next jsp automatically gets the new value.
I thought for Applet-servlet communication but my concerns are,as my applet is being refreshed continuously(around every 1 sec) and the value which i have to pass is changing every second and I dont know when user will click on the button of jsp so to pass that value of applet i have to do applet-servlet communication every second and that does not suit me as it consumes lot of time.
Can you suggest me any other solution so I can send value through jsp whenever button is clicked.
Thanks

HI Senthil Babu
Thanks for your reply.
But applet is very important for my application as i am showing some graphical representation on it. So I have to use applet. Now you told that i have to make temporary files on client's macvhine. You mean to say each time I have to store that value on client's pc through File I/O.
Is that? but that is also problematic 'cause it consimes much time and my application deals in milli seconds.
Pl. guide me considering that time is much important for my application so solution should not consume much time.
Thanks again,
Taral Shah

reply meThis is a little hard to follow and want to make sure I understand:
You can pass the value from page1 to page2. But when you submit on page2 to another page, the value is null?
My first recommendation is: Pull all HTML code out of scriptlets that is using out.println.
But to answer your question, you don't have the hidden fields in the <FORM> tag. They need to be places in the form tag in order for the form to pass the values when you submit. -

Dynamic Fonts in JSP With applet
Hi Buddies
My Multilingual web application uses a dynamic font , the technology provided by TrueDoc.com. Now the problem is the webpage works properly by making use of the dynamic fonts and I get stuck to life when I realised that my applet should also display using the dynamic font.
The dynamic font is a file with an extension of .pfr usually placed in the server and all the webpages will be bound to the server to make use of the .pfr font, there by making all the clients to view the sam font
irrespective of the fonts installed in the client machine.
How do i get goingThe applet is run on the client machine, so you have to include the .pfr with the applet code. Best bet would be to use a JAR for the Applet and package the .pfr inside there.

Getting option value in jsp: Urgent help will be appreciated
Hello All,
I am working on JSP. I will grade myself as beginner in JSP.
I am trying to solve since last 2 days, I just want to display the value of option tag, and not able to get it.
<table>
<tr>
<td>
<html:select name="ActionForm" property="overage">
<%
int i;
int[] arr1=new int[200];
for (i=0;i<=100;i=i+10)
arr1=i;
%>
<html:option value="/<%=i%>/"><%= arr1%></html:option>
<%}%>
</html:select>
</td>
</tr>
</table>
Please, ignore the syntactical error.
Now in above code I want to know what is being put up as value of option tag. By value I mean , I want see <html:option ]value="/<%=i%>/> . (Data marked in bold)
Your help will be appreciated. I tried couple of things such as getParameter(), get Attribute(), getOverage(). Some of it gave me value as "//", it skips the i variable.
I want to see what is being put up in value for every iteration of loopYeah I know. But thnx for the response.
I also got that error solved. you know what it was because of those bckslashes. i wrote it,
<html:option value="<%=i%>"><%=arr%> instead of
<html:option value="/<%=i%>/"><%=arr[i]%>
and that worked perfectly. I wish I could have known this before. It would have saved me lot of time. -

Getting hidden value with javascript problem
<html>
<body>
<form>
<input type="hidden" id="code" value="123">
</form>
</html>
when open the html file and type "javascript:alert(document.getElementById("code").value)" in the address bar, I get a message box with "123".
but when i do in the jsp with
<input type="hidden" id="code" value="<%=request.getParameter("code")%>">
and type the javascript in the address bar, i get "object not supported".
Can anyone tell me how to get hidden value in jsp with javascript?
thank you.There is no difference between a JSP or plain html, since javascript executes on the client side after the JSP is done processing. There is obviously something wrong with the HTML content after you input the request value, so check the generated HTML in your browser to see if there are any unwanted quotes in there or something.

Re: Embedding Applet in JSP which gets dynamic input| Pls help
Hi All,
We are into a project in Oracle Portal Server where in we want to embed a result of a standalone application(Which is applet) in JSP.
This standalone application generates applet based on the input it gets from the current application's database.
If it was static we could have used jsp:plugin but, it fails in our case!
We are clueless as to how to embed an applet which will pick up the data dynamically.
Can anyone of you help me in this regard?
Thanks & Regards
ArthiWell instead of generating entire applet ,you can have a generic applet which takes parameters as ( <PARAM name="name" value="value"> ) inputs and process those inputs to generate output.
In this case the output of the stand alone program would be a object. And in JSP page you need to access this object, then you can get the values which need to be passed to Applet.
Else
1.Identify the real path of the applet class file
ServletContext context = session.getServletContext();
String realContextPath = context.getRealPath(request.getContextPath());2.Copy the file to a standard location in your web application

How to get a value from applet in jsp?
Dear all,
I have a jsp page which includes a applet (in a form). User click to my applet and get the value.
and the jsp form can capture the value of the applet and send to servlet.
Is it possible?
If it is possible, how to do that?
Thanks.
Regards,
KinHi,
Yes it is possible. You have to use LiveConnect.
The classes required are netscape.javascript.*
They are located in the jaws.jar file (jre/lib).
Here is a copy of the page found at http://www.rgagnon.com/javadetails/java-0177.html
Read/Write HTML field values from JAVA
[Netscape AND IE4 compatible]
The netscape.javascript.* (LiveConnect) package provides facilities to directly manipulate HTML FORM components.
JSObject win = (JSObject)JSObject.getWindow(this);
JSObject HTMLInputText = (JSObject) win.eval("document.forms[0].elements[0]");
String testValue = (String)HTMLInputText.getMember("value"); // read form value
HTMLInputText.setMember("value" , testValue + "new stuff"); // write form valueBut this action requires a signed applet. in Netscape, you must PrivilegeManager.enablePrivilege("UniversalBrowserRead");
PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
before using an JSObject related to an HTML document.
But there is a workaround, simply pass the informations through Javascript functions!
[JSjava.java]
import java.applet.*;
import java.awt.event.*;
import java.awt.*;
import netscape.javascript.*;
public class JSjava extends Applet
implements ActionListener {
Button b1,b2;
TextField tf;
JSObject win;
public void init(){
setLayout(new FlowLayout());
tf = new TextField(10);
b1 = new Button("to FORM");
b2 = new Button("from FORM");
b1.addActionListener(this);
b2.addActionListener(this);
add(tf);add(b1);add(b2);
public void actionPerformed(ActionEvent ae) {
if (ae.getSource() == b1) {
// send TO FORM
JSObject win = (JSObject)JSObject.getWindow(this);
win.eval("setHTMLInputText('"+tf.getText()+"');");
if (ae.getSource() == b2) {
// receive FROM FORM
JSObject win = (JSObject)JSObject.getWindow(this);
tf.setText((String)win.eval("getHTMLInputText();"));
}[JSjava.html]
<HTML><HEAD>
<SCRIPT>
function getHTMLInputText(){
return document.forms[0].elements[0].value;
function setHTMLInputText(s){
document.forms[0].elements[0].value = s;

thank you all.

sambaYou want a database update to trigger an applet refresh? Can't be done.
However, you can have the applet periodically re-query the database and update its display with the information it retrieves. Just kick off a Thread that sleeps for a bit, wakes up, queries the db, updates the display, and goes back to sleep.
