Browser Support to open a file by clicking on filename

[SaiManasa Dasari]

Hi
Here is my code to open file by clicking on filename.

<%
 String         finalFilesForOpen     = request.getParameter("selectedopenfilename");
 if(finalFilesForOpen != null
            && finalFilesForOpen.trim().length() > 0)
    {
        File        file                 = new File(finalFilesForOpen);
        int         length               = 0;
        ServletOutputStream outputStream = response.getOutputStream();
        ServletContext      context      = getServletConfig().getServletContext();
        String              mimetype     = context.getMimeType(finalFilesForOpen);
        response.setContentType((mimetype != null) ? mimetype : "application/pdf");
        response.setContentLength((int) file.length());
        byte[] buffer = new byte[1024];
        DataInputStream inputStream = new DataInputStream(new FileInputStream(file));
        while((inputStream != null) && ((length = inputStream.read(buffer)) != - 1))
        {
            outputStream.write(buffer, 0, length);
        }
        inputStream.close();
        outputStream.flush();
        outputStream.close();
    }
%>
 <form name="downloadForm" action="example/jsp/applicationjsp/DocumentDownload.jsp" method="post">

<a onclick="openFile('<%=downloadfilePath%>');" onmouseover="this.style.textDecoration ='underline'" onmouseout="this.style.textDecoration ='none'" target="_blank"> <%=rowDownloadfilename%></a>
<SCRIPT language="JavaScript">
function openFile(filePath)
{
          window.open("example/jsp/applicationjsp/DocumentDownload.jsp?selectedopenfilename="+filePath+"");
}
</SCRIPT>
  </form>

If You want to open a file then simply you can execute a command from your java program to open that file.

if you want to get the file abc.pdf opened, You can use the following command...

String command = "abc.pdf";
Process child = Runtime.getRuntime().exec(command);

Before you are using this command set the path of the file....in command line with your java program like

if the file is in "c:/My Files/abc.pdf" then
String command = "cd c:/My Files";
Process child = Runtime.getRuntime().exec(command);

Except that this is in a web app and Java isn't useful for doing anything on the client unless it's an Applet.
