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". -W
