You can use "indexOf()" or "lastIndexOf()" to get the position of a char within a String. In this case it looks like "lastIndexOf()" might be what you need. However, you need to be a bit more precise with your requirement. Is it always the last instance of the character that you want?

Check out the String methods available to you here ( http://docs.oracle.com/javase/7/docs/api/java/lang/String.html).

Yes it can. You can use Java in the tMap expressions. If you want to do something a bit more complicated than one expression, you can code your own method in a routine which can be used in the tMap. Talend is just a code generator. Java can be used in a lot of areas.
