There is any way to expose constants in web services using axis??
Hello. My question is: There is any known way toexpose constants making use of axis1.2 : server side: class State implements Serializable { public static final String CONSTANT_1="CONSTANT_1"; public static final String CONSTANT_2="CONSTANT_2"; } client side: myWebService.setState(State.CONSTANT_1); I mean generating code from java2wsdl does not seem to generate static or final constants. Thanks in advance.
Constants and Web Services
Hello. Maybe a very stupid question but: I wonder is it possible to publish a provider service which has as parameter a complex datatype and this datatype has some constants . something like this : Provider Service public void setState(State state){ ... } Complex datatype Class State { public static final String CONSTANT_1="string1"; public static final String CONSTANT_2="string2"; public String value; public State(String value){ this.value= value; } } Is it possible to generate wsdl i such a way that also the string constants are published?. So that somebody willing to use setState service could just generate stubs (and constants) with wsdl2java thanks in advance.
Web Service Provider and Applet of JFrame
I have a question: There is any very simple way to get data from a Web Service provider (not a client) and show it in a JFrame or an Applet ?. I am trying to use RMI. First getting data trough the web service and then send it to an Applet trough an rmi call but i have some problems setting the java policy file, i get this error: java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: Hello (no security manager: RMI class loader disabled). Any idea how to do it in tomcat 5.5. There is any other alternative way to rmi ? Thanks in advance for any help.
Question a service request or response and an handler runs in the same thread??
My problem is to pass information from a Service-client to a ClientRequestHandler and then from a ServerRequestHandler to a Service-provider not making use of the MessageContext. So i' am thinking to use the ThreadLocal pattern to constuct a stateful singleton and in this way pass information from a Service to the Handler and vice versa. Now my question is: are a Service and an Handler or a chain of Handlers different steps of the same Thread. What Happens if for example i do the following: Service service1=new Service(); Service service2=new Service(); Call call1=service1.creatCall(); Call call2=service2.creatCall(); call1.invoke(EndPointRef_1); call2.invoke(EndPointRef_2); Are the different Requests and the subsequent operations of an Handler part of the same Thread ? Thanks in advance for any help.
How to dynamically configure an Handler in the Global Request and Response chain for different services?.
HOw it is possible to configure at runtime an Handler in the general chain, or anyway capable to intercept all the outgoing or incoming traffic generated by each service-Provider or Requestor? I have found this on the net: http://www.cetis.ac.uk/members/scott But in this way i need to attach my handlers to each Service and this is precisely what i don't want to do. { EngineConfiguration clientConfig=createClientConfig(); service.setEngineConfiguration(clientConfig); service.setEngine(new AxisClient(clientConfig)); } what i would like to do is to dynamically configure Handlers for all services. Is it possibloe to do something like the following??: { private EngineConfiguration createClientConfig() { SimpleProvider clientConfig=new SimpleProvider(); Handler GeneralHandler= (Handler) new BasicHandler(); GeneralHandler.setOption(MyOption,"blabla"); . Attach the Handler to all services return clientConfig; } And then ... EngineConfiguration clientConfig=createClientConfig(); .../... Pass the configuration to all services? }
Re: How to pass information between handlers and services.
The idea is that to pass information to an handler from the client-Application in such way that all subsequent service invocations will be intercepted, then Information will be added into the SOAPHeader and deliverd to different provider-services It should like really like the following: { // one time passing the info to an Handler in the General chain PassInformationToHandler( Info ); Service serice_1=new Service(); Service serice_2=new Service(); Service serice_3=new Service(); // Calls Call call_1 = (Call) service_1.createCall(); Call call_2 = (Call) service_1.createCall(); ... call_1.invoke(...) call_2.invoke(...) call_3.invoke(...) } // i don't want to do something like the following : { ... // Calls Call call_1 = (Call) service_1.createCall(); Call call_2 = (Call) service_1.createCall(); ... MessageContext messageContext_1 = call_1.getMessageContext() ; MessageContext messageContext_2 = call_2.getMessageContext() ; MessageContext messageContext_3 = call_3.getMessageContext() ; messageContext_1.setProperty("MyInfo", Info ); messageContext_2.setProperty("MyInfo", Info ); messageContext_3.setProperty("MyInfo", Info ); call_1.invoke(...) call_2.invoke(...) call_3.invoke(...) } I was thinking at two ways to solve this problem 1) Making use of the singleton pattern. Exchanging information saving it into a singleton object, and sharing it. 2) Dynamically attaching an Handler to all the Services, passing the information each time the handler is attached (configured). But this dynamic configuration works per service but i did'nt manage to attach an Handler to all the services. Any other idea ?

How to pass information between handlers and services.
I am trying to implement an application that does the following. Assume we have a client : startSomething(XMLFLAG) call.invoke(EndpointReference_1) call.invoke(EndpointReference_2) call.invoke(EndpointReference_3) An Handler has to intercept the different calls and put the XMLFLAG in the SOAPHeader of all the calls. On the Provider side an Handler has to intercept the call, get the XMLFLAG from the SOAPHeader and pass it to the provider service. In simple words there is a way to directly pass information between Client-Services and Client-Handlers and between Provider-Handlers and Provider-Services ??? Thanks in advance.
