Using myfaces tomahawk inputFileUpload componet
I am using myfaces tomahawk inputFileUpload componet for the following requirement
1. I need to upload images to my user profile page.
2. Resize the image to fit my desired image size to be shown on the page
Promblems
1. The file i upload is done fine and images also show but
the image is stored or refrenced to the local machine , so if i delete or change file location the image dosent show.
what i need is to store the images in a seperate folder on the server or any other place and image should point to that location.
2. Now the image uploaded displayed using jsf's
<h:graphicImage url="fileupload_showimg.faces"/>
component where "fileupload_showimg.faces"
is a jsp page containing the following code
which is a scriplet
<%@ page import="java.io.File,
java.io.InputStream,
java.io.FileInputStream,
java.io.OutputStream"%><%@ page session="false" %><%
String contentType = (String)application.getAttribute("fileType");
String fileName = (String)application.getAttribute("fileName");
String allowCache = request.getParameter("allowCache");
String openDirectly = request.getParameter("openDirectly");
if(allowCache ==null || allowCache.equalsIgnoreCase("false"))
{
response.setHeader("pragma","no-cache");
response.setHeader("Cache-control","no-cache, no-store, must-revalidate");
response.setHeader("Expires","01 Apr 1995 01:10:10 GMT");
}
if(contentType!=null)
{
response.setContentType(contentType);
}
if(fileName !=null)
{
fileName = fileName.substring(fileName.lastIndexOf('\\')+1);
fileName = fileName.substring(fileName.lastIndexOf('/')+1);
StringBuffer contentDisposition =new StringBuffer();
if(openDirectly==null || openDirectly.equalsIgnoreCase("false"))
{
contentDisposition.append("attachment;");
}
contentDisposition.append("filename=\"");
contentDisposition.append(fileName);
contentDisposition.append("\"");
response.setHeader ("Content-Disposition", contentDisposition.toString());
}
byte[] bytes = (byte[])application.getAttribute("fileSizeBytes");
if (bytes !=null)
{
response.getOutputStream().write(bytes);
}
%>
works fine but the image shown in its original size most of the time very large.
I tried to fix the image size by changing the code to
<h:graphicImage url="fileupload_showimg.faces" width="300" height="500"/>
But now the image is shown is deformed
i need it to be fixed in size and not deformed
