Hi,
have a look at the following.. it is a section of a simple main() type class
that gets the path of where it is stored. This will work with servlets as
well. The problem is that with win32 the path will be in the format
/c:/classes/, so you get rid of the first character, making it c:/classes/ -
which will work.
The problem is when you try to run the same code in linux. /home/rob/classes
might end up pointing to /usr/local/java/.../home/rob/classes.. which is a big
prob. But if it is only going to be run on one platform, end of problem
best regards,
Rob
Class cls = new OutputTestMain().getClass();
URL resource = cls.getResource("../test.txt");
System.out.println(resource.toExternalForm());
System.out.println(resource.toString());
System.out.println(resource.getRef());
System.out.println(resource.getFile());
String path = resource.getFile();
path = path.substring(0,path.lastIndexOf('/')+1);
PrintWriter out;
try {
out = new PrintWriter(new BufferedWriter(new FileWriter(path+"test.txt")));
out.println("hello");
out.println("wonder if this will work");
} catch ( Exception e ) {
System.out.println("error opening file for write");
}
