I hav tried to generate that xml by using StringBuffer & append, but it's not what i mean...
Anyone can help me?

Ok...i got it. But i still hav some problems.
This is the sample code that i used :
public class XMLCreator {
     //No generics
     List myData;
     Document dom;
        Element rootEle, mmsEle, mmsE;
        StringWriter stringOut;
        mms mms;
     public XMLCreator(String subject, String image, String sound,
                String video, String text, String sender, String recipient,
                int id, String date, String contentid) {
          mms = new mms(subject, image, sound, video, text, sender,
                        recipient, id, contentid, date);
                createDocument();
     public void run(){
          createDOMTree();
          print();
     private void createDocument() {
          //get an instance of factory
          DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
          try {
          //get an instance of builder
          DocumentBuilder db = dbf.newDocumentBuilder();
          //create an instance of DOM
          dom = db.newDocument();
          }catch(ParserConfigurationException pce) {
               //dump it
               System.out.println("Error while trying to instantiate DocumentBuilder " + pce);
     private void createDOMTree(){
          //create the root element <Mms>
          rootEle = dom.createElement("mms");
          dom.appendChild(rootEle);
          createMmsElement(mms);
     private Element createMmsElement(mms b){
          Element subjectEle = dom.createElement("subject");
          Text subjectText = dom.createTextNode(b.getSubject());
          subjectEle.appendChild(subjectText);
          rootEle.appendChild(subjectEle);
          //create url_image element and author text node and attach it to mmsElement
          Element imageEle = dom.createElement("url_image");
          Text imageText = dom.createTextNode(b.getUrl_image());
          imageEle.appendChild(imageText);
          rootEle.appendChild(imageEle);
          // & etc....
          return rootEle;
      * This method uses Xerces specific classes
      * prints the XML document to file.
     private void print(){
          try
               //print
               OutputFormat format = new OutputFormat(dom);
               format.setIndenting(true);
                        stringOut = new StringWriter();
               //to generate output to console use this serializer
               XMLSerializer serializer = new XMLSerializer(stringOut, format);
               //to generate a file output use fileoutputstream instead of system.out
               //XMLSerializer serializer = new XMLSerializer(
               //new FileOutputStream(new File("mms.xml")), format);
               serializer.serialize(dom);

              ie.printStackTrace();
        public String getStringOut() {
            return stringOut.toString();
}when i tried to show the stringOut.toString() in my jsp, it's only showed string like this :
The Lords Of The Ring http://localhost:8084/movie/lotr.3gp 6281321488448 6281321488448 123 0 20070220114851 LOTR.
1. Why this is happen?i want to generate xml which its format is like above.
2. How can i send this xml (put in msg parameter) using jsp (via web) without creating the mms.xml?
3. if i want to set the msg parameter equal to mms.xml - means that msg = mms.xml, what is the data type for msg? is it an object or anything else?
Thx b4 in advance...

How can I do sth like this ${requestScope.list.size} ?

Hi, I have 2 attributes which I pass like this
requsest.setAttribute("startPoint", 3);
request.setAttribute("myList", myList);
where myList is a ArrayList filld with objects. On jsp page I want to count 2 values first and last number:
<c:set var="firstNumber" value="${requestScope.startPoint+1}"/> - this works fine.
<c:set var="lastNumber" value="${requestScope.startPoint+requestScope.myList.size}"/> - this is impropper.
How can I use as integer size of list which is passed as request attribute. Is this possible?
I would appreciate any hepl.

Hang on. For such things you can build your own EL functions - it is very easy and involves only 4 steps.
1. Write a class containing a method (must be static) to calculate size of any list.
[Put the class in /WEB-INF/classes, so your file will reside as /WEB-INF/classes/myfunctions/MyFunctions.class]
package myfunctions;
import java.util.List;
public class MyFunctions{
     public static int getListSize(List list){
          return list==null?0:list.size();
}2. In your taglib add an entry (in case you don't have already create one) for the EL function:
[Say our taglib is mytags.tld in /WEB-INF]
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
     version="2.0">
     <tlib-version>1.0</tlib-version>
     <short-name>MyTagLib</short-name>
     <function>
          <description>List Size</description>
          <name>size</name>
          <function-class>myfunctions.MyFunctions</function-class>
          <function-signature>int getListSize(java.util.List)</function-signature>
     </function>
</taglib>3. Now in your JSP add following line to use your new EL function:
<%@taglib uri="/WEB-INF/mytags.tld" prefix="mt"%>4. And use as:
<input type=text value="${mt:size(requestScope.myList)}" />Note that there no issues using JSTL EL functions. My intention is to resolve your problem and at the same time to give you a glance how to write and use your own EL functions (might be useful in future).
Thanks,

My password protected phone was stolen and hacked into. How can I prevent someone like this from hacking into/getting around the passcode? They now have access to everything on my phone (I had a passcode to prevent this)

How can you prevent a hacker from bypassing your iphone passcode? My phone was stolen and someone hacked in and has access to everything on my phone and turned off "find my iphone." This is exactly what I wanted to prevent from happening and the reason why I had a passcode.

Turn on "Erase Data" in Settings>Passcode. That will wipe the data after 10 incorrect password attempts.
Turn off "Simple Passcode" in the same place and use something other than a 4 digit pin as your passcode.
Also make sure Find my iPhone is enabled so you can locate and if necessary, forcibly wipe the phone.

How can I make navigation like this...?

http://timeger.com/work/JoseCuervo/JoseCuervo_Facebook.php
I want to the user to be able to navigate within my site, like the navigation on this site. (the numbers on the right side of the screen re-populate the area with different images.)
Thanks so much!

Use mouse rollover with two images, one with just the text and the other image, rollover, with the oval around the text. You can link the first image to the page you want. This demo page has some examples: Mouse Rollover. The first two examples are hyperlink to other pages.

How can I format paragraphs like this?

I am a novice DW user and a novice at web design. I have a formatting challenge as follows. First my stylesheet and then the problem:
Could you please help me? I have this need well more than 1,000 places on my website. The insets vary, i.e. sometimes the first Line is inset 80px and the second and following Lines 120px, etc. Again, I don't understand much of this so please be explicit. Thanks very much!

Your insertion didn't come through. Ca you post a link to your web site? Or use the camera icon in the web forum to upload an image into your post showing how you want to format paragraphs.

How can I join images like this

I have downloaded many wallpaper images and they come in left.jpg and right.jpg packs (I use dual monitors) and I would like to join them together but it takes too long in Gimp, as the process is Image > Canvas size, resize, then paste and align and save. Is there a quick CLI way or something to do this ?? What would be the method? Much appreciated if possible, thanks.

tesjo,
Thank you so much!! I was fiddling with it and kept messing it up trying -append and -adjoin. That works perfect, thanks a lot

Thanks. But is there a difference between what you are proposing:
.indent {
         padding left: 200px;
And what I already have?
.col_5 {
          padding-left: 200px;
          padding-right: 50px
And if I put a <p><span......> I get a blank line between my Line 1 and Line 2. The <p> causes the blank line.
With just a <br /> (and no <p>) and then the <span class="col_5" the "col_5" command just is acting on the next line as in Example B. Actually class="col_5" is additive to the previous class="col_4" callout, and therefore the indenting is 160px plus 200px or 360px. In my Example B I used "col_1" after the "col_4" and get an indent of 160px plus 40px or 200px.

How can I show somehting like this?

[opt1] [opt2] [opt3] [opt4]
| Main Panel |
| |
| Sub Panel |
| |
Where opt1, opt2,... are tabs. When user click on different tabs, only Sub Panel will change.
Main Panel will always stays the same.
I was thinking about let Main Panel on TOP of a JTabbedPanel, and that JTabbedPanel has blank upper side.
Is this possible?

Well, the easiest way to do this, is using a JTabbedPane with tab location set to bottom ... ;-)
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JTabbedPane.html#setTabPlacement(int)
Another way to go about this would be to use a CardLayout for SubPanel and represent opt1 to opt4 by JButtons with an ActionListener or JComponents on which you register a MouseListener, then switch cards when the button or the component is clicked.

please help me.
Shyja

Hi,
First in context create node for 2 input field. Then disign layout for input filds and do data binding. Then create button and assign ON action event to it. In action method use wizard to read the values from the node.
DATA: Node type REF TO IF_WD_CONTEXT_NODE,
elem_node1 TYPE REF TO if_wd_context_element,
stru_node1 type ZEMP.
Node = wd_Context->get_Child_Node( Name = `S_NODE2` ).
get element via lead selection
elem_node1 = node->get_element( ).
get all declared attributes
elem_node1->get_static_attributes(
IMPORTING
static_attributes = stru_node1 ).
INSERT ZEMP FROM stru_node1.
If helpful reward points.
