Executing the sample
This service uses validators in places where the validity of the input parameters has to be checked. This is shown in the "addEmployeeQuery" operation, by having a length validator for the "lastName" field where the length of the value should be between 3 and 20. Also, the "email" field is validated using a pattern validator which uses a regular expression to check if it's a real email address.
Follow the steps below to demonstrate this functionality:
1. Run the "addEmployee" operation with the parameters, employeeNumber=6001; lastName=AB; firstName=Nick; email=test@test.com; salary=1500. After running the operation, run the "employeesByNumber" operation with the parameter employeeNumber=6001. Note that you are not getting any results. The reason is because, the earlier "addEmployee" operation has failed due to a validation failure. The lastName was 2 characters long.
2. Run the "addEmployee" with parameters, employeeNumber=6001; lastName=ABC; firstName=Nick; email=test-test.com; salary=1500. In this case also, the entry will not be added because the email address is not valid.
3. Run the "addEmployee" with parameters, employeeNumber=6001; lastName=ABC; firstName=Nick; email=test@test.com; salary=1500. Here the entry will be successfully added and you will get a result as follows:
