JSP Front End Testing

With the JSP front end, all correct operations dealing with valid employee ids will work.

As there is no error correction and no validation, there are a lot of bad cases:
Insert: Anything can be inserted. An employee id with null for every field is possible.

Update: With a valid id, all the fields can be updated with junk data, even nulled. Without a valid id, the server creates an exception.

Delete: Valid ids will be deleted, invalid ones will create an exception report.

Find: Valid ids will be displayed, invalid ones will display a blank page.
