Display KM image in JSP

Question

Hi All,
I have image in KM folder. I want to display it in JSP as a html image. I am able to
access the image using below code.
<%
try {
     IUser sapUser = componentRequest.getUser();
     com.sapportals.portal.security.usermanagement.IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
     IResourceContext resourceContext = new ResourceContext(ep5User);
     String path = "/documents/Images/sample.gif";
     RID imgRID = RID.getRID(path);
     IResource resource = ResourceFactory.getInstance().getResource(imgRID, resourceContext);
     BufferedInputStream bufIn = new BufferedInputStream(resource.getContent().getInputStream());
byte[] imagebyte = new byte[bufIn.available()];
bufIn.read(imagebyte);
catch(Exception e ) { }
%>
<img border="0" width="147" height="66" src="">
Using above code image is stored in a byte array. How to set this as html img tag source.
Thanks
Joe

Hello Sreekanth,
there are two approaches how to get an KM image into your JSP.
<b>1) The easy one</b>
Just put into SRC attribute of your IMG tag next link:
<b>/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/</b>documents/Images/sample.gif
Bold part is an access link to KM root. In this case - be aware, the users have to have access rights to given KM object (could be inherited from parent folder).
<b>2) Through a stream</b>
In this case you don't have to set access rights for a given resource for all users, you will read the image from Runtime (using ice_service context for example).
And you can refer to that image as you refer your application. The only thing you need to do - is to write image byte stream to response in your application. Example:
          ByteArrayOutputStream PictureStream = ...;
          if (request.getParameter("Get_Image") != null) {
                    response.setContentType("image/gif");
                    ServletOutputStream sos = response.getOutputStream();
                    response.setHeader("Content-Disposition", "attachment; filename="image.gif"");
                    response.setHeader("Cache-Control", "no-cache");
                    PictureStream.writeTo(sos);
                    sos.close();
               return;
And then you address this image stream in your SRC attribute of IMG tag following:
<u><i><your application url absolute or relative (relative is siggested)>?Get_Image=true</i></u>
