How to include a forward slash(/) in my regular expression

Question

Hai All,
I am having a regular expression which should accept only A-Z, 0-9, (underscore) and .(period) .
<property name="patterns" value="[A-Z0-9\\._]*" />
Now i need to add /(Forward slash) to this expression.
<property name="patterns" value="[A-Z0-9\\._/]" />
But when i add it it is accepting both Foward slash and Backward slash.
Can someone guide me such that it accepts only A-Z, 0-9, Underscore, period and a Forward slash(/).
Thx in advance..

Looks like you had it right to me.
import java.util.regex.Pattern;
import junit.framework.TestCase;
public class RegexTest extends TestCase{
     public String patternString = "[A-Z0-9\\./]*";
     public void testRegex(){
          Pattern pattern = Pattern.compile(patternString);
          assertTrue(Pattern.matches(patternString, "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"));
          assertFalse(Pattern.matches(patternString, "abc"));
          assertTrue(Pattern.matches(patternString, "24.7"));
          assertTrue(Pattern.matches(patternString, "24/7"));
          assertFalse(Pattern.matches(patternString, "21\\7"));
}It works in my tests.
What happends to this "patterns" property? Where and how are you using it?
