GML 3.2.1 - NetBeans Error

Hi All
In my WSDL, I've imported gml.xsd file:

  • [b]schemaLocation="http://schemas.opengis.net/gml/3.2.1/gml.xsd"[/b]

but when I create a new Java Application using NetBeans importing this WSDL, I receive this message:

  • [b][ERROR] Property "Rows" is already defined. Use to resolve this conflict.  line 652 of file:/Users/valentino/NetBeansProjects/app1.java/xml-resources/web-service-references/vale/wsdl/schemas.opengis.net/gml/3.2.1/geometryPrimitives.xsd[/b]
  • [b][ERROR] The following location is relevant to the above error  line 684 of file:/Users/valentino/NetBeansProjects/app1.java/xml-resources/web-service-references/vale/wsdl/schemas.opengis.net/gml/3.2.1/geometryPrimitives.xsd[/b]

[b] [/b]
What does It mean?
I need to use only "TimePeriodType", "BoundingShapeType" and "CircleByCenterPointType".
Thank you
