Displaying error messages

Thanx alot for the reply.

I am trying to return a string as a error message as a result of the validation which is not getting displayed on the screen, but if i try to throw the exception, exception is displayed correctly on the server console. Please guide me on this.

thanx once again

No I havent wrapped my invoke part in rule.

Below is the snap shot of the code:

******************************************************************

public string validateZip(String fieldValue) throws Exception {

boolean invalidTF = false;

string message = null;

String regExp = "^[\\w\\-\\s]*$";

try {

//check to see that regulat expression and RE are not null

if (regExp != null && fieldValue != null

&& 0 < fieldValue.length()) {

RE re = new RE(regExp);

if (re.match(fieldValue)) {

invalidTF = true;

}

}

} catch (RESyntaxException ex) {

ex.printStackTrace();

}

if (invalidTF == true) {

//throw new Exception("Please enter value in correct format invalid expression");

message = "invalid format";

}

return message;

}

*******************************************************************

I am expecting Invalid format to appear on the screen
