HTMLLIElement li = (HTMLLIElement)appHTML.createElement("LI");
Text txt = appHTML.createTextNode(name);
li.appendChild(txt);
appHTML.getElementById("name").appendChild(li);

and i want to assign a hyperlink to it,
I have id with name also so I thought that using id i will
create javascript like
function popup(id)
     if(id==1)

How can share data between jsp pages using beans??

any one can give me code for 2 jsp pages with bean that share data for them

<jsp:usebean name="yourBeanName" type="com.whatever.foo" scope="session"/>
this will look for a bean named yourBeanName in the scope specified by the scope attribute. If none was found, the container will instantiate one with the no arg constructor for your bean and place it into the proper scope.
if your bean had a method getName(), you could then on your jsp do:
<%=yourBeanName.getName()%> to print the results of the method to the page. there are other ways to do the actual placing of the output on the page, but this is the most direct.

How avoid spl charecters in jsp forms using java script..

hi,
iam using following function for escaping spl charcetrs..
function checkEscapeCharacter(currentField) {
var string = currentField.value;
var iChars = "\"*|,?_:<>[]{}';()@&$#%!~`^-+=\\/";
for (var i = 0; i < string.length; i++) {
if (iChars.indexOf(string.charAt(i)) != -1){
alert("illegal");
currentField.value="";
currentField.focus();
return false;
but with code aftet alert iam removing alll entered value..i just want to remove the illegal chacters..iam calling this onkeyup event..after alert it should remove spl char from string and assign it back to text fileld.
regard,

Hello,
I wrote the following two methods, you pass the first of these the String
you want to check, and the character you want removed. It then returnes the
'cleaned' string.
The second is very similar, but instead of removing the character, it replaces
it with another.
These only do one character at a time though, which is not exactly what your
after.
   public String stripChar(String string, String charToStrip)
        String newString="";
        StringTokenizer st = new StringTokenizer(string, charToStrip);
        while (st.hasMoreTokens())
            newString = newString + st.nextToken();
        return newString;
public String replaceChar(String string, String charToStrip, String charToAdd)
        String newString="";
        StringTokenizer st = new StringTokenizer(string, charToStrip);
        while (st.hasMoreTokens())
            newString = newString + charToAdd + st.nextToken();
        return newString;
    }

Any suggestions Plz??

As the [HTML specification|http://www.w3.org/TR/html401/interact/forms.html] states, you should be setting the enctype to multipart/form-data to be able to upload files to the server. In the server side, you need to process the multipart/form-data binary stream by parsing the HttpServletRequest#getInputStream(). It is a lot of work to get it to work flawlessly. There are 3rd party API's around which can do that for you, such as [Apache Commons FileUpload|http://commons.apache.org/fileupload] (carefully read the User Guide how to use it).
You can also consider to use a Filter which makes use of the FileUpload API to preprocess the request so that you can continue writing the servlet code as usual. Here is an example: [http://balusc.blogspot.com/2007/11/multipartfilter.html].

How to raise a pop-up page using HTMLB

Hi friends,
   Can anybody tell me how to raise a pop-up page using HTMLB.But don't use webdynpro.
I want to set a TextField on PAGE A,and a button ,when i click the button,
it raise up a page B,Page B contains a HTMLB tree,when i click the tree node,
The textfield value in Page A will get the node text.
waiting for your great help!

Hi Raven,
In case of HTMLB you can use javascript to pop up the new page on click of the button.
onClientClick="popUpMethod();" of button call a java script method popUpMethod(). which will call the other page. below is the code for opening other page as pop up
function popUpMethod(){
          window.open("T1Report.htm",'_blank',
      " status=yes,toolbar=yes,menubar=yes,location=no, scrollbars=yes ");
in this method you just need to change the name of your htmlb page like T1Report.htm with your html page.
please revert if you require more information

How to embed 3D models in web page using JAVA?

Hello
I'm doing a project at University to create a virtual tour of a village. I am creating the buildings in MAYA using polygon planes and cubes and then exporting to VRML.
I plan to embed each individual model into a separate web page. Then when the user clicks on a location in a 2D map they will be taken to the web page containing that building.
However, I can't work out how to embed these 3D models into web pages using JAVA. Can anyone help me with this, please?
Also, I've been told to use JAVA 3D to interact with the project but am unclear as to how JAVA 3D would be used in this project - aqny ideas/suggestions welcome!
M.

If you use Java-plugin, you can embed Java3D in a web page.
Here is the URL(http://www.geovista.psu.edu/products/demos/LorenzAttractor3D/index.html) which used Java3D.
I hope this helps.
