= "name") String studentName) { StudentDTO student = new StudentDTO(); try { student = studentService.findStudentByName(studentName); } catch (Exception e) { return new ErrorActionResponse("student couldn't find by name"); } return student; } As usual this doesn't work because of return type is StudentDTO and I try to return another type of class: ErrorActionResponse. ErrorActionResponse is an error class that has detailed information about error. How can I design my web service architecture that can handle exception handling in web services c# error situations? (At my REST architecture I write error information into response and send error to client side) java web-services design error-handling share|improve this question asked May 28 '12 at 15:48 kamaci 21.1k45149269 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted If you want to return a Collection (as stated in a comment to my earlier answer), I suggest you create a Map with two keys. If there is no exception, first key-value pair will contain "students" string and StudentDTO collection, respectively. And, second key-value pair will contain "exception" string and null value, respectively. If there is an exception, first key-value pair will contain "students" string and null value, respectively. And, second key-value pair will be "exception" string and an ErrorActionResponse object, respectively. Example: No exception case: Map

Comments By Mamoon Yunus and Rizwan Mallal JavaWorld | Dec 20, 2006 12:00 AM PT RELATED TOPICS Core Java Enterprise Java Web Services Comments Web services—the foundation of service-oriented architecture (SOA)—are self-contained, modular applications that one can describe, publish, locate, and invoke over a network. Web services operate at a level of abstraction similar to the Internet. They are agnostic to operating system, hardware platform, communication protocol, or programming language and have blurred the boundaries between network devices, security products, applications, and other IT assets within an enterprise. Almost every IT asset now advertises its interface as a Web Services Description Language (WSDL) interface ready for SOAP/XML messaging. Using SOAP for system-to-system messaging and WSDL for interface description, IT professionals now have unprecedented flexibility in integrating IT assets across internal and external corporate domains. It is this flexibility of distributed computing provided by Web servic
reference, here's how the Web Service looked in the last article:import javax.jws.WebMethod; import javax.jws.WebParam; import javax.jws.WebService; // The url will now be .../HelloService @WebService(serviceName="HelloService") public class SimpleWebService { // The method element in the XML will now be SayHello @WebMethod(operationName="SayHello") // @WebParam will rename the input from arg0 to name public String sayHello(@WebParam(name="name") String name){ return "Hello " + name + "!"; } }And this is the basic client I'll start with for testing it, for information about creating a web service client in NetBeans click here:import simon.webservice.*; public class SimpleClient { public static void main(String[] args) { try{ HelloService service = new HelloService(); SimpleWebService port = service.getSimpleWebServicePort(); System.out.println(port.sayHello("Fault")); }catch(Exception e){ System.err.println(e.getMessage()); } } }When this is ran with the current Web Service, it'll say "Hello Fault!"Throwing Our Own ExceptionWhile just throwing an Exception can be done, this is a bad idea. It carries the issue of the generated Exception class clashing with java.lang.Exception unless they are explicitly referenced.To get around this, we'll make our own Exception that maps onto a SOAP fault. To be in compliance withsection 2.5 of the JAX-WS specificationour custom exception must:Extend Exception.Be annotated with @WebFaultUse a fault bean used to store the messageImplement the two constructors and the method described in the specHere's the SimpleException class with the mothods required by the JAX-WS spec:import javax.xml.ws.WebFault; @WebFault(name="SimpleException") public class SimpleException extends Exception{ private SimpleExceptionBean faultBean; public SimpleException(String message, SimpleExceptionBean faultInfo){ super(message); faultBean = faultInfo; } public SimpleException(String message, SimpleExceptionBean faultInfo, Throwable cause) { super(message, cause); faultBean = faultInfo; } public SimpleExceptionBean getFaultInfo(){ return faultBean; } }The fault bean, which is a plain old java object (POJO):public class SimpleExceptionBean { private String message; public SimpleExceptionBean() { } public SimpleExceptionBean(String message) { this.message = message; } public String getMessage() { return message; } }Now we need to modify the SimpleWebService to throw our
