Web Service in Spring 4 framework to be accessed by .Net Client Application

I have developed web service in spring 4 framework that contains some method like getCompany(), getUnit(), getCustomer(). WSDL file for web service is generated by source Code. These method are working fine while accessed by test java program.

These web service methods are to be used by client application i.e Window based Application build in .NET Framework. All methods are working fine when application is run on development environment but when apppliocation is run on another machine the only getCustomer() method work fine and in case of other method, error- "Error in deserialization of body of reply message of operation getUnit() displyed". Note :- Structure and syntax of all method are same.

Please help and Thanks in Advance.
