I have a java web service which is configured in glassfish server. When I try to invoke it dynamically from ASP.NET it generates the following message

Unable to import binding 'foxwsPortBinding' from namespace 'http://fox/'. System.InvalidOperationException: Unable to import binding 'foxwsPortBinding' from namespace 'http://fox/'. ---> System.InvalidOperationException: Unable to import operation 'pop_inc'. ---> System.InvalidOperationException: The element 'http://fox/:pop_inc' is missing. at System.Xml.Serialization.XmlSchemaImporter.FindElement(XmlQualifiedName name) at System.Xml.Serialization.XmlSchemaImporter.ImportElement(XmlQualifiedName name, Type desiredMappingType, Type baseType) at System.Xml.Serialization.XmlSchemaImporter.ImportMembersMapping(XmlQualifiedName name) at System.Web.Services.Description.SoapProtocolImporter.ImportLiteralMessage(String messageName, MessagePart[] parts, SoapBodyBinding soapBodyBinding, SoapBindingStyle soapBindingStyle, Boolean wrapped) at System.Web.Services.Description.SoapProtocolImporter.ImportMessage(String messageName, MessagePart[] parts, SoapBodyBinding soapBodyBinding, SoapBindingStyle soapBindingStyle, Boolean wrapped) at System.Web.Services.Description.SoapProtocolImporter.GenerateMethod() at System.Web.Services.Description.ProtocolImporter.GenerateClassForBinding() --- End of inner exception stack trace --- at System.Web.Services.Description.ProtocolImporter.GenerateClassForBinding() --- End of inner exception stack trace --- at System.Web.Services.Description.ProtocolImporter.GenerateClassForBinding() at System.Web.Services.Description.ProtocolImporter.GenerateCode(CodeNamespace codeNamespace, ImportContext importContext, Hashtable exportContext) at System.Web.Services.Description.ServiceDescriptionImporter.Import(CodeNamespace codeNamespace, ImportContext importContext, Hashtable exportContext, StringCollection warnings) at System.Web.Services.Description.ServiceDescriptionImporter.Import(CodeNamespace codeNamespace, CodeCompileUnit codeCompileUnit) at real_time_integration.DynamicInvocation() in d:\prototype\framework\real_time_integration.aspx.cs:line 120

I have seen in some forums (e.g. http://support.microsoft.com/kb/820122) that the cause for this is when Wsdl.exe cannot obtain complete information about an element that is declared in an external XML Schema but I am not able to fix it. Would you please provide specific suggestion on it?
