What does it mean to be "Always On"?

oh well, spoke too soon
i'm using this and can read the ocntents of my file

FileInputStream fis = new FileInputStream("a.vm");                  
InputStreamReader isr = new InputStreamReader(fis,"UTF8");                  
Reader in = new BufferedReader(isr);                  
int ch;            
while ((ch = in.read()) > -1)
{
stringbuffer.append((char)ch);
}

however when i display the file contents in my broswer it displays it as an html page, i just want it shown as plain text,

can anyone show me how i can display the contents of the .vm file just as palin text without the broswer formatting it back to an html page?

many thanks

If you're using servlets, on your response object you need to call response.setContentType("text/plain")

For jsps, you would use this:
<%@ page contentType="text/plain"%>

If you have other html stuff in your page and want the page to still be an html, but this text to be displayed as it is, you will need to escape it. There are several ways to do that, let me know if you need it.

If you're just opening the file with a browser, there's not much you can do. Easiest way would probably be to generate an escaped version of the file.

The code that you posted - is it reading the file in a servlet and then printing the contents using out.println () ?

If you do it in a jsp, you could just do it with <c:out value="${yourVarHere}" />. If you use a servlet, you just need to do these kind of replaces:
& to &amp;
< to &lt;
> to &gt;

Assuming you have a huge String, in JDK5 you would do print(yourString.replace("&","&amp;").replace("<","&lt;").replace(">","&gt;"));

Replace this
<td><%=contents %></td>
with this
<td><%=contents.replace("&","&amp;").replace("<","&lt;").replace(">","&gt;") %></td>

I assume contents is a String. If not, replace it with
<td><%=contents.toString().replace("&","&amp;").replace("<","&lt;").replace(">","&gt;") %></td>
