How to display graphics dynamically in JSP

I use JSP to call a servlet to get the output . The output is in svg format. I do not hope to create a svg file to store the output from servlet. I wope to embed the svg dynamically in the jsp page
Anybody knows the solution. Many thanks in advance
Cheers,
.

Because the output from Servlet is in text format not binary.
So the tag <IMAG></IMAG> does not work .
the output is similar as
<svg viewBox="0 0 360 270">
<style type="text/css"><![CDATA[
.aS{ font-family: monospace; text-anchor: middle;
font-size: 35px; stroke: Blue; fill: Red; }
]]></style>
<g>
<text x="60" y="90">+2%</text>
<polyline points=" 110,80 110,80 210,80 210,80" />
<text x="60" y="180">-2%</text>
<line x1="110" y1="170" x2="210" y2="170" />
<line x1="110" y1="120" x2="210" y2="120" />
<text x="280" y="130">4:0</text>
<text x="160" y="200">1</text>
<text x="110" y="150">-</text>
<text x="185" y="50">Sample - Name</text>
<text x="185" y="240">Minutes/km (2003/1/7)</text>
</g>
</svg>
If I keep the output as a **.svg file. then embed it in jsp. it is OK.

How to display servlet dynamically generated image ?

Hi,
How to display servlet dynamically generated image ?
I have a servlet generating a buffered image in the doGet. I want to display the image in a jsp page with other information. I'm not able to get it properly displayed.
**Try n# 1 **************************************************************
This displays my image but nothing elle :
ServletOutputStream sos = pResponse.getOutputStream();
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(sos);
encoder.encode(img);
**Try n# 2 ****************************************************************
I tried also :
In the servlet :
     request.setAttribute("renderedImage", img);
and in the jsp page :
     BufferedImage image = (BufferedImage) request.getAttribute("renderedImage");
     <img src="<%=ImageIO.write(image,"jpeg",response.getOutputStream())%>" width="300" height="280"/>
This last try draws big crap in the jsp page, thank you in advance.
Nelson

Call another servlet from the IMG tag. Have the servlet stream out the image using ImageIO (instead of writing HTML).

</applet>
</html>
I only get the first frame picture for ever by my html.But the jpg file is dynamic.
Why?
Can you help me?
Thanks.

Hi,
Add this line inside your run() method, right before your call to repaint():
if (image != null) {image.flush();}Hope this helps,
Kurt.

How to display the dynamic region in full size

Hi,
I'm not able to display the dynamic region in full size.
In my page, i attached a dynamic region which refers a page fragment. This dynamic region contents are showing as small (scroll is there but i want to display fully).
How to do this?
Thanks in advance,
Sundar

More than likely it has something to do with your parent layout element. I'd suggest putting your region in an af:panelStretchLayout or similar container that stretches its children. Some of the elements can be a little tricky though, such as af:panelTabbed. It has an attribute that must be set to stretch its first child.

Hi,
I think that its necessaries to use AJaX.
I am implemeting something like that.
I have a input text that works like a filter and depends on what my user types in input text I populate my table with some information.
In order to do that, I put in my JSP a div with an Id and I used ajax, like that:
function ajaxFunction()
          var xmlhttp;
          if (window.XMLHttpRequest)
          xmlhttp=new XMLHttpRequest();
          else if (window.ActiveXObject)
          // code for IE6, IE5
          xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
          else
          alert("Your browser does not support XMLHTTP!");
          xmlhttp.onreadystatechange=function()
                                                  if( xmlhttp.readyState==4 )
                                                       document.getElementById("tabelaResponsaveis").innerHTML = xmlhttp.responseText;
     var resp = "<f:invokeUrl var='solicitacao' methodName='getResponsaveis'/>";
     xmlhttp.open("POST",resp,true);
     xmlhttp.send(null);
getResponsaveis is a method inside my BPM that returns a HTML code (the table HTML code with all the information that I need to show.
I Hope to help

Hi Sunil,
The code from bean class is here,
public void listDetails(String releaseGroup,String releaseCode)
throws Exception
                try
                     if (mRepository == null )

                     try
IFunctionTemplate                                         ft=mRepository.getFunctionTemplate("BAPI_REQUISITION_GETITEMSREL");
myFunction=ft.getFunction();
               catch (Exception ex)
               throw new Exception(ex + "Problem retrieving JCO.Function object.");
      if (myFunction == null)
     System.exit(1);
mConnection.execute(myFunction);
               JCO.ParameterList input = myFunction.getImportParameterList();
                       input.setValue(releaseGroup,"REL_GROUP");
                       input.setValue(releaseCode,"REL_CODE");
                       input.setValue(releaseFlag,"ITEMS_FOR_RELEASE");
                         System.out.println("Imported");
                     catch (Exception ex)
                          ex.printStackTrace();
                          System.exit(1);
                      mConnection.execute(myFunction);
            JCO.Table codes = null;
           codes =myFunction.getTableParameterList().getTable("REQUISITION_ITEMS");
           size =codes.getNumRows();
           if (size == 0)
              System.out.println("No value matches the selection cretaria");
           purchaseRequisitionNo = new String[size];
           item   = new String[size];
           requestorName = new String[size];
           description = new String[size];
           creatorName = new String[size];
           purchaseRequisitionDate = new String[size];
           plant = new String[size];
          // getter methods
     public int getSize() { return size; }
     public String getPurchaseRequisitionNo(int i){return                                                        purchaseRequisitionNo<i>; }
      public String getItem(int i) { return item<i>; }
     public String getDescription(int i) { return description<i>; }
     public String getCreatorName(int i) { return creatorName<i>; }
     public String getPurchaseRequisitionDate(int i)
                                         {return purchaseRequisitionDate<i>; }
     public String getplant(int i) { return plant<i>; }
Now in the JSP page get the number of entries in the table and try to get row by row from the bean class using the row number.
<%
int count = PR.getSize() ; // This method will return the number of
rows in the table.
for ( int i = 0; i < count ; i++ ) {
%>
<TR><TD ALIGN = "center"><%= PR.getPurchaseRequisitionNo(i) %> </TD>
<TD ALIGN = "center"><%= PR.getItem(i) %> </TD>
<TD ALIGN = "center"><%= PR.getDescription(i) %></TD>
<TD ALIGN = "center"><%= PR.getCreatorName(i)%> </TD>
<TD ALIGN = "center"><%= PR.getPurchaseRequisitionDate(i)%> </TD>
<TD ALIGN = "center"><%= PR.getplant(i)%> </TD>
<% } %>
Hope this is a simple way to get your requirement.
Let me know if this does not help you.
Thanks

How to display graphics larger than canvas size?

How do I display graphics larger than canvas size in Java AWT?
I tried setting the canvas size() to a value larger than my monitor size, and then adding scroll bars to the canvas, but the scroll bars and the canvas won't go beyond the monitor size in pixels, which is only 800, so the large graphic I try to display gets cut off at the bottom.
How can I overcome this problem? Has anybody encounter a similar dilemma before?

How to display Arabic content in JSP ?

Hi all,
I used the following encoding method to display arabic content in JSP page.
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<meta content="text/html; charset=UTF-8" http-equiv="content-type"/>
I also set -Dfile encoding=ISO-8859-6 in the JVM Options.As a result the arabic data is getting displayed .
Variable "data" contains the actual arabic data.
function updateArabicData(data){
try{
document.getElementById('divtag').innerHTML=""+data;
}catch(err){
<html>
<body>
<div id="divtag" lang="ar-sa"></div>
</body>
</html>
But the problem is the arabic data getting displayed in JSP (within the <div>)seems to be jumbled up.The users say that the arabic words within a single sentence are not arranged correctly.They are mixed up.Please help me with a solution.
Edited by: Alance on May 27, 2010 5:34 AM

Data is retrieved as follows
if(msg.getField("GEN_UNICODE_MESSAGE_1")!=null){
resultString=resultString+"N"+""+new String((byte[])msg.getField("GEN_UNICODE_MESSAGE_1").value.get(0),"ISO-8859-6");
with content Type set as response.setContentType("text/html;charset=ISO-8859-6");
ISO-8859-6 -since the data contains arabic news.
