How to display images [Local Path] of JSP in firefox?

Hi,
I have been facing this problem so long. I have tried every possible option available on the net. like changing '\' to '/' and give complete path like 'file:///D:/images/image.gif' etc. but still facing the same problem.
Its shows the image perfect in IE6 when I pass local drive path but in case of Firefox it never display anything, but when I tried to get Img Src path in alert it gives correct in IE6 and FX1.5 both.
Plz. provide the solution if anybody face the same prob.

Create a servlet which listens on /image or so and which sends the image to the HttpServletResponse#getOutputStream().
For example img src="/image?id=123" should invoke the ImageServlet with the request parameter ID = 123. Then locally open 123.jpg and send it to the response.
Also see http://www.google.com/search?q=imageservlet
Don't forget to make it hack-safe. Strip slashes and output images only.

How to display images and information

how to display images and information(e.g. like questions) on a jsp page that stored in a database

Look As far as i can see....
Utlimately every file could be expressed as a bytes buffer.
so say if you have a bean called Choice Bean which is expressed as
public class ChoiceBean{
   private String choiceid;
   private String choicedesc;
   private byte image[];
   public void setChoiceId(String choiceid){
          this.choiceid = choiceid;
    public String getChoiceId(){
           return this.choiceid;
      public void setChoiceDesc(String choicedesc){
           this.choicedesc = choicedesc;
       public String getChoiceDesc(){
           return this.choicedesc;
       public void setImage(byte image[]){
              this.image = image;
         public byte[] getImage(){
              return this.image;
}QuestionList.java:
===============
public class QuestionList{
     private List<ChoiceBean> choicelist;
      /*Other member variable declarations*/
       public List<ChoiceBean> getChoiceList(){
                /*Custom code where you may build the list by querying the DA layer*/
                 return this.choicelist;
     public int search(String choiceid){
             int index = -1;
             for(int i =0 ; i < this.choicelist.size() ; i++){
                    ChoiceBean cb = this.choicelist.get(i);
                     if(cb.getChoiceId().equals(choiceid)){
                            index = i;
                            break;
             return index;
    /* Other member method declarations */
}and you are retreving List<ChoiceBean> from DB using your query & have created a session attribute / <jsp:useBean> named ChoiceList
NOTE: sometimes your application server can go out of bounds as you are consuming a lot of memory by creating an arraylist object.
use the following methodology to display images & choices
sample.jsp:
=========
<jsp:useBean id="QuestionList" class="com.qpa.dao.QuestionList" scope="session"/>
<TABLE>
<%
/* QuestionList.getChoiceList() is a method which fetches data from the DB & returns it in form of List<ChoiceBean> */
List<ChoiceBean> choicelist = QuestionList.getChoiceList();
for(int i =0 ; i < choicelist.size() ; i++){
%>
<TR>
<TD><%!=choicelist.get(i).getChoiceId()%></TD>

<TD><IMAGE src="ImageServlet?choiceid=<%!=choicelist.get(i).getChoiceId()%>"/> </TD>
<TD><%!=choicelist.get(i).getChoiceDesc()%></TD>
</TR>
<%
%>
</TABLE>
<%
    session.remove("QuestionList");
%>
NOTE: usage of JSTL or any other custom built tag-libraries makes life more simpler in the following case
ImageServlet.java:
===============
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        byte buffer[] = null;
        HttpSession session = request.getSession(false);
        /*getting the QuestionList from the session*/
        QuestionList ql = null;
        String choiceid = new String("");
        try{
             choiceid = request.getParameter("choiceid");
             /*getting the QuestionList from the session*/
            ql = (QuestionList) session.getAttribute("QuestionList");
        } catch(Exception exp){
        if(choiceid.equals("") == false && ql != null ){
            List<ChoiceBean> clist = QuestionList.getChoiceList();
               assuming that you have created a serach method which searches the entire choice list and would give you
               the index of that object which is being refered by unique choiceid and returns -1 if not found
            int index = QuestionList.search(choiceid);
            if(index != -1){
               ChoiceBean cb = clist.get(index);
               buffer = cb.getImage();
        if(buffer != null){
             // assuming that we have stored images in JPEG format only
             JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder(new ByteArrayInputStream(buffer));
             BufferedImage image =decoder.decodeAsBufferedImage();
             response.setContentType("image/jpeg");
             // Send back image
             ServletOutputStream sos = response.getOutputStream();
             JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(sos);
             encoder.encode(image);
        } else {
           response.setContentType("text/html");
           response.getWriter().println("<b>Image data not found</b>");
}However,i still feel there are few loopholes with this approach where Application Server can eat up a lot of heap space which may result in outofmemorybound exception.
Hope this might help :)

How to display images on my internal isight?

Hi,
I just bought the new iMac 2 gig dual. Running on 10.5.2.
I wanted to know how to display images on my screen during a video conference chat without resorting to holding up a print out to the camera? I need something where I can switch from video mode to image mode and show a single image at a time if I need to. All that while still talking of coarse. If it isn't possible with my iSight software, can you point me to other software I can download and still use my built in cam?
I hope I was clear enough in asking this.
Thanks
Liban

Welcome to Apple Discussions, Liban
iChat can do what you want, but I do not know of any web-based video chat site that can.
Look for Help or Support information on the site you are using or ask the Webmaster if his site has the capability to do what you want.

How to display a pdf file in jsp

hi,
How to display a pdf file in jsp iam having a class which will return fileinputstream of the file object. the pdf file is in server.
regards
Arul

A JSP is a combo of HTML and Java, so you can't really "display" a PDF file in a JSP.
You can provider a href link to the PDF file in your JSP.
You can use some utility package to read the contents of the PDF, pull certain things out of it, and display that in your JSP as html
In a servlet you can set the content type to application/pdf and write the binary data of the PDF back to the browser. Once the browser finishes reading in the data it should open the PDF.

How to display image?

Hi all,
How to display image from the database table in the adobe form by using web dynpro abap?
I want to display image in the adobe interactive form by using web dynpro abap.
Please help me.

Hi Srini,
If you go through the article you might have seen the following piece of code
*** Send the values back to the node
lo_el_z_if_test_cv->set_static_attributes(
EXPORTING
static_attributes = ls_z_if_test_cv ).
" here ls_z_if_test_cv has the image in XSTRING format which has beeen retrived using METHOD get_bds_graphic_as_bmp of CLASS cl_ssf_xsf_utilities
" In your case you need to just use the select query n fetch it from your table; ( provided your image is store in XSTRING format )
How is your image stored in your database table ?

How to display images on local disk(outside of WebContent of WAR) in jsp?

In a web application, I want to display images on local disk(outside of WebContent of WAR) in jsp. I couldn't put it in "WebContent/images/" because the images are portraits of users and they could be changed dynamically. If I put images in "WebContent/images/", I have to transfer the images back and forth every time when I update my WAR file.
Obviously, in jsp, something like
"<img src="/home/username/images/local/PRTR.jpg" />"
doesn't work.
Is it durable to store the images at somewhere else like "/home/username/images/local/" in the server's local disk?

Hi aiGrace,
You have to transform your file path into the appropriate URL, this way :
try {
    File file = new File("D:/Test/MyPic.jpg");
    System.out.println(file.toURI().toURL());
} catch (MalformedURLException ex) {
    ex.printStackTrace();
}Then, you insert the URL in your img tag.

Issue with displaying images from bestseller.inc.jsp

Hello all,
I'm new in developing with NWDI and I'm having this small problem:
in bestseller.inc.jsp (which includes productlist.jsp) there are two links with a product's code and a products description, which when clicked, navigate to productDetailsISA.jsp with the details of the product. While the images of all the products from other jsp's (for example from ProductsISA.jsp) display correctly in the ProductDetailsISA.jsp, there is a problem with the images of the products from bestseller and recommendations jsp's (they both include productlist jsp).
The code for creating the links *in productlist.jsp is the following:
<li> <a href="<isa:webappsURL name="b2b/productdetail.do"/><%=ShowProductDetailAction.createDetailRequest(product,displayScenario) %>">
                      <%=JspUtil.encodeHtml(product.getDescription()) %>
                    </a> </li>
and the code for displaying products's images in ProductDetailsISA.jsp is this:
<td width="7%" rowspan="2" headers="Product image">
               <img src="<isa:imageAttribute guids="DOC_PC_CRM_IMAGE,DOC_P_CRM_IMAGE" name="webCatItem" defaultImg="mimes/shared/no_pic.gif"/>"   width="250" height="250"/>
          </td>
I have no idea how isa:imageAttribute tag works, so I was wandering if this problem is somehow connection with the inner workings of this tag.
Could someone help please?
Thank you very much in advance

so much wrong with this post...
a) use the code tags to format the code. Now it is an unreadable mess
b) scriptlets in your JSP. I don't even want to look at that mess. Learn how to combine servlets and JSPs to create clean, readable and maintainable code in which view logic and business logic are separated. The rule: no java code in your JSP, only tags and EL expressions (learn about JSTL).
So you get a blank screen. When you do "view source" in your browser, do you see anything there? If nothing, check if you are behind a proxy server. The solution to a post of not too long ago was that the blank screen was being caused by faulty proxy server settings (the user figured it out himself, I don't know what was done to solve it).
If all this fails you will have to do some debugging magic using your favorite IDE. It will probably be something stupid you are overlooking in the code. It is annoying, but debugging code that does not work is a big part of your job. Better get good at it.

How to display images on a servlet generated page???

Hi, I am developing an app in which I must display some messages, each message may have an image. The images are saved in the database. I do not want to save the image on the filesystem but instead of that I want to send the image as an attribute to the page but I dont know then how to display it. I have no idea about how to do that! Any help on this would be very appreciated!

mmm yes I know that the img tag displays an image but I am asking how to display the image without saving the file into the server filesystem, I mean something like:
1.- getting the bytes from the Database
2.- getting an Image object
3.- pasing it to the request as an attribute
4.- getting that attribute from the request
5.- displaying it on somehow directly from the image var or something.
the src parameter of the img tag takes as a string the path of the image, but i dont want to save it.

How to display images in a table column?

Hi,
In a VC model, I have to display images in a table column for each record found.
How can this be done?
Regards,
Nitin

Hi Nitin,
It can be done by adding to the table the Image control (can be found under Advanced Controls in the Compose panel).
In the URL property (in the Configure panel of the Image control) you can define any expression that will return the image URL. For example:
="http://hosting.site.url/"&@ImageNameField

How to display the navigation path in the masthead.

hi,
   Requriement is to display the navigation path in the masthead.
   how to achieve it.
regards,
Shanthakumar.

Hi,
I think you want to show the bread crumb in your masthead to show the path to the actual navigation node.
This functionality already exists in page title bar iview you need to just enable the options in the page title bar iview in your active framework page.
If you want to have this Functionality in your masthead, just check the codes of page title bar iview and do similar coding in your masthead.
NavigationEventsHelperService has alot of helper methos which will give you the currently clicked navigation path nodes and more. So also check them.
NavigationEventsHelperService service =
                (NavigationEventsHelperService) PortalRuntime.getRuntimeResources().getService(
                    NavigationEventsHelperService.KEY);
            NavigationNodes navNodes =
                (NavigationNodes) service.getNavNodesListForPath(request, INavigationConstants.NAVIGATION_CONTEXT_ATTR);
