Java type extensions in WSDL

Question

Hi,
I would really appreciate if someone could share an example of how java types can be used in WSDL.
I am trying to define messages of type java.sql.Connection. The WSDL should look something like:
But of course I cannot reference java.sql.Connection from the WSDL
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:tst="http://test.org/test/"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
name="TestService"
targetNamespace="http://test.org/TestService/">
<wsdl:types>
<xsd:schema targetNamespace="http://test.org/Test/">
<?xml version="1.0" encoding="UTF-8"?>
<element name="testType">
<complexType>
<sequence>
<element name="connection" type="java:java.sql.Connection"/>
</sequence>
</complexType>
</element>
</xsd:schema>
</wsdl:types>
<wsdl:message name="testMessage">
<wsdl:part name="RequestParameter" element="tst:testType"/>
</wsdl:message>
<wsdl:message name="testMessage">
<wsdl:part name="ResponseParameter" element="tst:testType"/>
</wsdl:message>
<wsdl:portType name="testInterface">
<wsdl:operation name="TestOper">
<wsdl:input message="tst:testRequestMessage"/>
<wsdl:output message="tst:testResponseMessage"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="testServiceSOAP" type="tst:testInterface">
<soap:binding style="document"
transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="test">
<soap:operation soapAction="http://test.org/test/ "/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="testService">
<wsdl:port binding="conn:testServiceSOAP" name="testServicePort">
<soap:address location="http://localhost:8080/Axis/services/testServiceSOAP" />
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
Is there a workaround?
Thanks.

OK, but what do we do if an application is using several database web services that should perform operations in the same session simply because it is too time consuming to authenticate every time a different web service is invoked?
Do we ask for user name/password for every web service?
Use the same connection (which you say is impossible) or
Somehow keep the user name / password and reuse it when invoking another web service?
Thanks
