Read image using PJC

Question

Hi,
We are converting Oracle Forms from 6i to 11g. We have some forms that use read_image_file to read image. It was .bmp file and now we can only use .gif/.jpg file on web and the image is very blurry.(we use the same .gif source file for image and icon for icon buttons, the icon is very sharp)
I tried to use PJC to read the image and image is very sharp now. I am able to read the image from local drive, like c:\my_image.gif while testing from my local PC. I would like to know how to read image from application server, where put the file and what configurations needed.
Or any solutions are welcome. I am new to Java, please help.

Hello,
I totally agree with Mark. As soon as you have created a virtual directory on the Forms server, you can reach the files stored in the corresponding physical directory.
Here is some code to get the Forms HTTP server URL (assuming that you pass only the virtual directory as file argument e.g: /forms/images/my_image.jpeg)
        String s = (String)value ; // full filename
        try {
          if(s.startsWith("http:") || s.startsWith("ftp:")
          || s.startsWith("www.") || s.startsWith("file:") || s.startsWith("/forms")) {
            initialURL = s ;
            URL url = null ;
            if(s.startsWith("/forms")) {
              // getting the Forms Main class
              try{
                Method method =
                   m_handler.getClass().getMethod("getApplet", new Class[0]);
                Object applet = method.invoke(m_handler, new Object[0]);
                if (applet instanceof Main) {
                   formsMain     =  (Main)applet;
                   String sDocBase = formsMain.getDocumentBase().toString();
                   int i = sDocBase.indexOf("/forms/") ;
                   sDocBase = sDocBase.substring(0,i);
                   initialURL = sDocBase + s;
              }catch(Exception ex) {System.err.println(" !!! ReadImage() Unable read the image\n\t"+ex.toString());}
            url = new URL(initialURL);
            // get the image there
        } catch(Exception ex) {
          System.out.println(" !!! ReadImage() Unable to read the image " + s + ": " + ex);
        } Francois
