Hi, I want to create a client for a series of previously unknown services and I don't want to generate stubs for every possible service. After some research, I found out that using apache axis is possible for a client to dynamically download the WSDL and invoke operations on the service without the stubs. As GT 4.2.0 is based on Axis 1.4, I tried the same solution when developing my client. As an example, I coded and deployed the Math Service from chapter 6 of the book "Globus Toolkit 4: Programming Java Services". Even though the book is based on a previous version of Globus, I was able to set the service running on GT 4.2.0. The Math Service's files are those available at http://www.gt4book.com and I didn't alter them. The client included in the package works just fine, the service is invoked and the values are returned correctly.
My client code is the following: public class ClientDynamic { public static void main(String[] args) { String serviceURI = args[0]; Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(new URL(serviceURI)); call.setOperationName(new QName("http://www.globus.org/namespaces/examples/MathService_instance","add")); call.addParameter("add", XMLType.XSD_INT, ParameterMode.IN); call.setReturnType(XMLType.AXIS_VOID); Integer a = new Integer(1); call.invoke(new Object[] {a}); } } full code at: http://pastie.org/695942 When I run the new client, the following error message arises: AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. faultActor: faultNode: faultDetail: {http://xml.apache.org/axis/}stackTrace:org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. full error at: http://pastie.org/695954 It appears that there's something wrong in the way I set up the parameters for the method. Any thoughts? thanks for your attention. -- __________________________________ João Marcelo Uchôa de Alencar Computer Science BSc. jmarcelo.alencar(at)gmail.com http://simetriade.blogspot.com Linux User 398939 __________________________________
