Errors :

Below are the errors at highlighted 

1. The part 'parameters' has an invalid value 'Employee' defined for its element. Element declarations must refer to valid values defined in a schema.

2. The part 'parameters' has an invalid value 'EmployeeResponse' defined for its element. Element declarations must refer to valid values defined in a schema.

   3. The operation specified for the 'addEmp_Binding' binding is not defined for port type 'addEmployeePortType'. All operations specified in this binding must be defined in port type 'addEmployeePortType'.

Answer 1

Answer to my question is that there was an issue with namespaces. Once I corrected the namespaces, the below errors were resolved:

1. "The part 'parameters' has an invalid value 'Employee' defined for its element. Element declarations must refer to valid values defined in a schema."

2. "The part 'parameters' has an invalid value 'EmployeeResponse' defined for its element. Element declarations must refer to valid values defined in a schema."
