Secure doGet parameter in Servlet

Question

I'm doing a simple register form and I need to pass some parmeters in url, however I'm concerned about the security in java. in PHP I used to use

mysql_escape_string

To make sure no special characters is passed to the variable. however I'm not sure if thats needed in Java.

the question is : is it safe to use request.getAttribute(arg0) directly or do I need to secure it using some special method ?

Answer 1

There is an answer to that question in Java - escape string to prevent SQL injection .

I believe that the best thing to do is not to encode your command as a string, but to use a PreparedSatements and set the parameter using its methods, like SetInteger, SetBoolean as so on.
