I have a servlet that I'm trying to read from a file and write it back out with new objects added to it, but the the servlet can not find the file.  It's running on Tomcat so i'm almost sure it has to do with the catalina.policy file.

I believe that i need to do something similar to the following but i'm not sure if it is correct and if it is where do i need to place it in the catalina.policy file.  Also, would i need to remove anything from the catalina.policy file?

grant codeBase "file:${catalina.home}/webapps/ROOT/conf" {
      permission java.io.FilePermission "${catalina.home}/webapps/ROOT/conf  myfile.txt", "read,write,delete";
};

Or do you guys have any other ideas as to why it may not be able to find the file?

whats the error?
more likely that it can't find the file than a security exception. Why are u using a security manager?

If its not finding the file try using the ServlketContext getRealPath() method toi get the file path
