Incorrect WSDL generated

I'm trying to use Apache Axis toolkit to implement a web-service (from the JBuilder IDE). The problem is when I try to expose the web-service the WSDL generated doesn't meet the specification:

The < extension > tag doesn't have "base" attribute. For example:

<complexType name="SinkEventCategory">
<simpleContent>
<extension>
<attribute name="_value" type="xsd:string"/>
</extension>
</simpleContent>
</complexType>

If you look here, you can see, that this attribute is required.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html
/a81fc9e9-18f6-4145-9fcf-f6788ea1acf6.asp

And if I try to add web-reference from Biz-Talk server to that service it informs about an error "Schema with the targetNamespace='http://SpsDocumentum.SinkMessage' has invalid syntax. The 'base' attribute is either invalid or missing."

I tried to upgrade my Axis to 1.2.1, but nothing changed.
I will be thankful for any help.
