Hi,

I have an email validation regex where the mvel matches doesn’t seem to work. I have created 2 rules where test1 uses the Java String matches and test2 uses the mvel matches. Test1 works but test2 doesn’t. I am using Drools 4.0.3 and JDK 1.6.0_02.

rule "Test1"

when

// This works

        email : String()

eval( !email.matches( "^[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+(\\.[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+)*@[a-zA-Z0-9]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(\\.[a-zA-Z0-9]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*\\.[a-zA-Z]{2,6}$" ) )

then

        System.out.println( "1-Invalid Email Address: " + email );

end

rule "Test2"

when

// This doesn't work

        email : String( toString not matches "^[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+(\\.[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+)*@[a-zA-Z0-9]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(\\.[a-zA-Z0-9]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*\\.[a-zA-Z]{2,6}$" )

then

        System.out.println( "2-Invalid Email Address: " + email );

end

Here’s the output using email addresses x.x@x.com (valid) and x.xx.com (invalid):

test1-Invalid Email Address: x.xx.com

test2-Invalid Email Address: x.x@x.com

test2-Invalid Email Address: x.xx.com

The regex expressions are exactly the same. Am I doing something wrong here?

Thanks,
