Viewing Sample Data File Errors
One or more XML elements in your sample data file is not valid according to the schema declared.
The View Errors dialog shows you the XML text in your sample data file and the validation errors found in the file.
The errors were generated after the file was checked against the schema declared in the selected WSDL file.
Click on an error message in the bottom half of the dialog to highlight the line in the file that contains a validation error.
You can add the sample file and correct the errors later.
