converting contextPath for Linux

[jondubya]

I'm trying to convert a piece of code that I got working on Windows, but I am unable to convert for Linux. I'm trying to upload an image using <input type="file" name="filename" size="50">

The following is the submitting page(upload.jsp) which attempts to upload the file located from the previous page, written exactly as it is for my Windows server.
--------------------------------------------------------

<%@ page import="java.util.*,java.io.*"%>

<%
String path=request.getParameter("filename");
String newPath="";
int count=0;

if(path!=null)
{
ArrayList arr=new ArrayList();
StringTokenizer st=new StringTokenizer(path,"\\");
while(st.hasMoreTokens())
{
arr.add(count,st.nextToken());
count++;
}
// create ur own path

newPath="C:\\Tomcat5\\webapps\\meetings\\xmasxonference\\upload\\"+arr.get(count-1);
int c;
FileInputStream fis=new FileInputStream(path);
FileOutputStream fos=new FileOutputStream(newPath);
while((c=fis.read())!=-1)
{
fos.write((char)c);
}
}

out.println("Thanks for using");
out.println("<br>");
out.println("<br>");
out.println("1.File1 Uploaded from :: "+path);
out.println("<br>");
out.println("<br>");
out.println("2.Uploaded File1 is Saved in :: "+newPath);
%>
--------------------------------------------
I've tried setting the following

newPath = /home/tomcat/jakarta-tomcat-5.0.18/webapps/meetings/xmas/images/"+arr.get(count-1);

and changing the tokenizer, as well as using
String appPath = application.getRealPath("/");
to get a relative path, which is preferable but with no success.

Any pointers, anyone? TIA dubya

Well any path using the file syntax "C:/bla" is not going to work on linux.

What are the errors ?
Where do you actually want to save the file ?
BTW, saving a file to the webapp directory is seriously bad form. What would happen when you wanted to deploy the webapp again ? Much better to save uploaded files in a standard, backed up, data directory.

Hi

I am little confused with the code , If I understood it correctly you are trying to upload a file using <input type="file"/> from client to the server? I think your code will work only if the client and server are sitting on the same machine . More over in the previous page the HTML form should be of type multipart/form-data and you cannot access the patameter uisng request.getParameter("path") if the form of type multipart . I might be wrong as you mentioned it is working in Windows. Any how If you need the context path of the upload.jsp you can get it using

<%=this.getServletConfig().getServletContext().getRealPath("/")%>

Sedj has some good comments a well.

Appart from all posted before, take care when parsing the path, it might not contain \\ at all but /.

Cheers,

Thanks for the pointers, I've taken your advice and am now trying to avoid saving in the application folders. Having got a working page, I've just discovered my problem now is that JSP doesn't support multipart/form-data enctypes! So I can upload an image but I cannot pass regular form data across at the same time so I'm just looking through jakarta-commons as a solution. Thanks to all for your help.
