I cannot launch java method from jsp page
I upload jsp file (index.jsp) and java file (easyTesting.java) on server and cannot launch the method from easyTesting.java.
Use :
TomCat 6 on UNIX , server version 5.1.41-3ubuntu12.10
this is my index.jsp
`<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Layer Easy testing</title>
</head>
<body>
<form action="poi.jsp" method="post">
<INPUT type="button" value="Create script file" onClick = <% link.startCode(); %>
"window.location.reload()"><br>
<br>
Select POIs type
<div align="left"><br>
<input type="radio" name="poi" value="1" checked > dynamic<br>
<input type="radio" name="poi" value="2">static<br>
<input type="radio" name="poi" value="3"> both<br>
<INPUT type="submit" value="save" ><br>
</div>
</form>
</body>
</html>
`
and java file package layar;
import java.io.*;
public class easyTesting
{
public void startCode()
{
File f = new File("http:79.125.23.143/~lezv/layertestnew.php");
if(!f.exists())
{
f.createNewFile();
}
else
{
f.delete();
}
}enter code here
}
And when I open http://79.125.23.143:8080/lezv/index.jsp
I get the next errror

Could you please help me
The method is being called, but encounters an exception:
java.io.IOException: Permission denied
java.io.UnixFileSystem.createFileExclusively(Native Method)
java.io.File.createNewFile(File.java:900)
layar.easyTesting.startCode(easyTesting.java:12)
The exception says that you do not have permissions to create the file.
File f = new File("http:79.125.23.143/~lezv/layertestnew.php");
That is a bit of a weird file name. Could it be that you need to translate the URL you want that PHP to have into a local file path? As it is, those slashes will most likely be interpreted as directory names, so you'd need to at least make sure that any parent directories exist.
