Java+axis the problems encountered in the process of calling ASP.net Web service by client and the solving method

Background: The company cooperates with an operator, the operator provides the interface document, the data flow is bidirectional in the document, the communication between the carrier and the company uses the Web service way, the two sides are mutually client and server side. The problem I encountered this time was when the operator's client invoked the Web service on my company's server. Need to specifically note that: operators have dozens of partners, so the client code can not be modified by a partner, the Web Service development environment of the partners are not the same, most of them are in the Java language development, and my company is developed with VS2005.
Process:
The part of the interface documentation involved is as follows:
User Data Synchronization (syncuserdata):
string font>

integer /font>

valign= "Top" width= " valign= "Top" width= "

index /p>	parameter Name /font>	req	type	size o:p>
1 /td>	mobile	user number
2 /td>	spid	m	string	21	partner identification
3 /td>	service span>	m /span>	21	business code
4 /td>	action span>	m /span>	4	user action
5 /td>	time	m	string /span>	14	timestamp
6 /td>	desc	m	string	255	reason description
7	Terminal	M	String	4	Terminal type

Carrier clients use the Web service client invocation that is implemented by the JAVA JDK 1.5+axis and provide specific debugging examples:

Package Smp.webservice.client;

Import java.rmi.RemoteException;

Import javax.xml.rpc.ServiceException;

}

}

String EndPoint= "Http://127.0.0.1/WebTest/Service.asmx";

Try ...{
int i=sc.syncuserdata ("13312345678",  "3735127", "834621", New Integer (8), "20080101120000" , "desc","9" , EndPoint);

System.out.println ("Result: " + i);
} Catch(Exception e)...{
E.printstacktrace ();
}
}
}

Where the value of endpoint is used to invoke the Web service address of my local. NET development.
