Also, Java is far stricter on syntax for regular expressions than anything
else I've seen. You can't just test your stuff at a unix prompt or using
grep to see if it works. That's just the first step. I generally use the vi
find command.

Read up on regular expression, what you just wrote there is not valid.

Hi,

 

 

Has anyone used the "matches" operator? 

In our application we need to support startWith, endsWith operators for
string variable. I am thinking of using matches operator. But the 'matches'
operator is not working. I am trying the following code

 

rule "Hello World"

      when

            m : Message(message matches "Hello*")

      then

            System.out.println( "Hello World"); 

end

 

 

 

And the value set in the message is "Hello World". But it is not going into
the then clause.

 

If anyone has already used matches operator I would like to know how we can
use it for startswith, endsWith. How do we specify the regular expression?
Can we use "*"

 

 

Thanks,

Ashwini
