Regular expression with drools (special characters /* )

I'm trying to make a rule to catch invalid characteres. Those are & < > /* ' " --

I already managed to "catch" all the symbols except the /*

My code is:

rule "Invalid Chars"
when
    c : Class ( field matches ".*[&<>'\"].*|.*(--).*" )
then
    // DO SOMETHING     
end

My regex is below. But when I try to add the /* symbol. I get this regex 

.*[&<>'\"].*|.*(--).*|.*(\/\*).*

But when I try to run I get this error:

line 1:28 no viable alternative at character '*' line 1:33 mismatched character '' expecting '"' java.lang.IllegalStateException: ### errors ### [Error: illegal escape sequence: *]~

How to "catch" all these invalid characters?

Solution

  • Here's minimal Test with * escaped but / not:

    public static void main(String[] args) {
    if("Hallo /* Test ".matches(".*[&<>'\"].*|.*(--).*|.*(/\\*).*")) {
        System.out.println("ILLEGAL");
    }
}
