Fixed.

it's a great article but with an terrible bug on the code example (terrible
because i've spent three hours debugging my own code to discover this
problem); on the spfileswsdl.aspx, the xml for uploadDocument webmethod is:

      <s:element name="UploadDocument">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="strFilename"
type="s:string" />
            <s:element minOccurs="0" maxOccurs="1" name="fileContents"
type="s:base64Binary" />
            <s:element minOccurs="0" maxOccurs="1" name="pathFolder"
type="s:string" />
          </s:sequence>
        </s:complexType>
      </s:element>

notice the property name of the first and the third elements; strFilename
and pathFolder.

and the webmethod method header is:

[WebMethod]
public string UploadDocument(string fileName, byte[] fileContents, string
targetFolder)

notice that here, the first parameter is fileName (instead of strFilename)
and targetFolder (instead of pathFolder)

so, as the name of the method params are not equal, the first and the third
params are received as null params, and the second is received Ok. If you
rename the webmethod params as the spfileswsdl.aspx params and refresh the
webmethod, the params are received ok
