[Axis2] Problems about Axis2 client accessing ZSI(Written in Python) simple "Echo" web services

[卢宾]

Hi, all,
  I write a webservice using Python, implementing a simple 'Echo' method,
and use a simple Axis2 client to access this webservice,  I do the following
steps:
  1. wsdl2java.bat -uri http://localhost/Echo.wsdl (generating two java
files)
  2. write a simple client to invoke the webservice
 then , I got the following errors:

<SOAP-ENV:Body xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";>
<SOAP-ENV:Fault><faultcode>SOAP-ENV:Client</faultcode><faultstring>Unparseable
message</faultstring><detail>
<ZSI:ParseFaultDetail xmlns:ZSI="http://www.zolera.com/schemas/ZSI/";>
<ZSI:string>Any cannot parse untyped element</ZSI:string>
<ZSI:trace>/soapenv:Envelope/soapenv:Body/ns1:Echo/in_str</ZSI:trace>
</ZSI:ParseFaultDetail>

</detail></SOAP-ENV:Fault>
</SOAP-ENV:Body>
 *My wsdl document is :*

So what's the problem here? Thanks a lot!
