I have written an exception class that extends java.lang.Exception. I get errors on the following lines of code

super(message);

I get the following error on the code above:

"SignatureCardException.java": Error #: 300 : constructor Exception(java.lang.String) not found in class java.lang.Exception at line 22, column 2

and on...

			

			super(message + '
			

			' + exception.getMessage());
		

I get the following error everywhere I have the getMessage() method:

"SignatureCardException.java": Error #: 300 : method getMessage() not found in class java.lang.Exception at line 36, column 38

When I bring up the code helper for the Exception class I only have equals(Object) listed. Please help. I didn't have this problem with JBuilder 5. It's just been happening in JBuilder 6.

Thanks in advance.
