Hi friends:

In a JApplet, I want to add a JButton to SplitPaneDivider.But the code seem's don't work property. My code is:

////////////// TestApplet extends JApplet ////////////////
public class TestApplet extends JApplet {
public void paint(Graphics g) {
JPanel f=new JPanel();
f.setPreferredSize(new Dimension(300,200));

f.setLayout(new BorderLayout());

JButton jep=new JButton("b");
JSplitPane jspcontent=new JSplitPane(JSplitPane.VERTICAL_SPLIT,f,jep);

BasicSplitPaneUI bspUI=(BasicSplitPaneUI)jspcontent.getUI();
JButton b=new JButton("test");
BasicSplitPaneDivider divi=bspUI.getDivider();


///////////// end //////////////////

The divider can't display the JButton, why?

But in a frame (None JApplet ) application, it can work property. Does the JApplet can't use BasicSplitPaneDivider ?

Hi friends.

I want to implement the Hotmail's function. Does anyone use hotmail? You can add many attachment to one mail. And it can add the value(file's path) to a table ,finally,it send the table's data to server. Can jsp do this?

Thank you for your fast reply.
I know your means. It need set the document header. But I think the main problem is that how to write all the data to a Stream? And send the xml stream to clients? Should I use inputstream or pipestream?

HI everyone:

I am a new developer in webservice soap. I come across a problem.
I want to invoke a soap method which return a List for example:

Now I want to display them in client's browser. What client will see in browser is :

But I don't know how to send the List to client and display them. Could I use Inputstream to do this?
Must I create xml document in server and send it to clients? I expect that I can do this using Stream.
Anyone can tell me how to send the data using Stream.

Thks for your reply
I change the code to
"if(v.isEmpty)" but I get a nullpointer Exception when I first run the jsp.
I change two file to jsp.They are all jsp file.It also can't work property.
I think I will say the my main meaning:
I am writing a email system using javamail.I want to implement file upload in my mail system.I also want to user can upload many file.So I place a vector value in jsp page.When user add a file name the vector will add one.The Vector will send to servlet after user upload all files.
But I come across two problems:
1: how to add a hyperlink to the mail attachment? Because the attachment is stored in the mail server so I don't know how to get it.What I only can get is a inputstream.It is the attachment's inputstream support by javamail API.
But how to change the attachment's inputstream to a File So when user click it the attachment will be download?
2.I change the code ,but when I refresh the page vector will add one
Mybe javascript can solve it?

Hi friends:
I am writing a mail systems.I can receive email attachment using javamail API. But I don't know how to add a hyperlink to the attachment so when user click the hyperlink the file will be download to disc.
I means that I want to add a hyperlink to the attachment,the hyperlink will get the file's path in mail server.Because the mail's attachment are stored in mail server so I don't know how to get it in my servlet.
what I can do is get a inputstream using messagePart.getInputStream();. I only can get a inputstream in servlet.How to change the inputstream to a File when user click it and download it?

I means that when I refresh the jsp page the item will add one.

Hi everyone:
I am writing a E-mail system using javamail and I expect the user can add attachment to their mail.Add client can attach several attachments. So I write two pages,one is jsp:

<%Vector v=new Vector();session.setAttribute("allfiles",v);String file=request.getParameter("upfile");if(null!=file){ v.add(file); session.setAttribute("allfiles",v);}for(Enumeration e=v.elements();e.hasMoreElements() {out.println("File:"+e.nextElement().toString());}%><a href="#" o n c l ick="window.showModalDialog('addfile.html','Title','status:no;dialogHeight:320px;resizable:no');">Add</a>
Another is html:
<SCRIPT LANGUAGE="JavaScript"><!--function send(){alert("hello");opener.document.location="t.jsp"; self.close();}//--></SCRIPT></head><body><form action="t.jsp" name="uploadform" ENCTYPE="multipart/form-data">select File:<input type="file" name="upfile"/><INPUT TYPE="button" o n c lick="send()" value="sendToParent"/></form>
vector will get all the file and will be send to a servlet finally.
When user click "Add",it will open a ModalDialog that user can choose file.After choose file user click the button "sendToParent",the child window will close and the file name will send to t.jsp.
So t.jsp will add the value to the Vector and display it.
But when I click button after choose file the t.jsp display nothing. : (
Why the Vector can't get the value ( file path in the disc)? There is any error in my code ? Help!
Thks! :roll:

Hi everyone
I am writing a forum.I want that the page go to another page after wait 5 seconds. I means that when user click post he will go to a page " please wait 5 seconds,if you don't want to wait, click Here" Then the page will go to another page after 5 second. It like Javaranch forum!
But the problem is that I display the data using <html:logic Taglib.And I use "request.setAttribute("data",iterator)" the set the data to request.If I do above things Tomcat will says:"can't find data in any scope".
I know why this happen because there is not any data in request after the page redirect.
How to fix it? Anyone had thinked it?Help :roll:
