Hi all,

I am working on drools. I would like to remove Special characters which
are existed in the data i.e. replacing special characters with null.
Following is the code:

rule "Wild Character validation"
when
c : CustomerInfo(customerName != "");

It is much better to write a condition that selects just the objects you're really interested here, i.e., the ones containing the characters you want to eliminate, thus:

c: CustomerInfo( customerName matches ".*[*#].*" )

then

int l = c.length();
int ch = 0;
int i = 0;
for (i = 0; i < l; i++) {
if (data.charAt(i) != "*"|| data.charAt(i) != "#"){
continue;
}
ch++;
data.setCharAt(i, "");
}
c.setCustomerName(data);
end

I assume that you assume that data is a String, but you haven't assigned it a value. And even if you do, you cannot modify a String. This is simple Java coding, and I'd say that you should go and study a Java text book.

Here's the right hand side code I'd use:

String data = c.getCustomerName().replaceAll( "[*#]", "" );
modify( c ){ setCustomerName( data ) }

I don't think you want to replace these characters with "null". I think you just want to remove them from the string, so that
"foo*bar#baz" becomes "foobarbaz".

Is there any wrong in this code? If so please help me out. Waiting for your
suggestion .

Thanks and Regards,
Lalitha.
