问题 We have a JAX-WS webservice deployed in a WAR in JBoss EAP 6.4.0 (JBoss AS 7.5.0) that delivers a predefined WSDL and XSD: @WebService(endpointInterface = "package.MyPortType", targetNamespace = "http://target.name.space", wsdlLocation = "/WEB-INF/classes/myService.wsdl", serviceName = "myService", portName = "myServicePort") public class MyService implements MyPortType { ... } JBoss correctly deploys the webservice and publishes the given WSDL as http://localhost:8080/myApp/myService and

问题 I am working on a web app in which the client JavaScript library (ExtJS) sends requests to my Struts-enabled backend with a JSON request payload. My problem is that I can't figure out how to get the variables from the payload into my Action class.

I'm trying to use struts2-json-plugin as an interceptor. Struts

问题 I have an application deployed at localhost on JBoss 6.0 AS. This application has one remote EJB bean called ExampleEJB. Now I'm trying to code a simple client application that consumes ExampleEJB. This client application will not be deployed at any application server. The idea is to code a simple Java SE client program. I've written the following trying to perform a lookup: Properties env = new Properties(); env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");

问题 I have inherited a legacy EJB application that was built as an EJB 3.0 with session beans and JPA. I am migrating from WebSphere 8.0 where the application worked without issues. I have tested on WebSphere 8.5.5 classic and have no issues, however, we have decided for strategic reasons to use WebSphere Liberty. I am deploying two ear files on the application server, 1 which is a front end EAR app and one which houses the EJB (JPA) application. Both applications run ins the same JVM. I have

问题 There is a xml file in the blobstore which looks like : <?xml version="1.0" encoding="UTF-8"?> <Blobs> </Blobs> The following servlet uploads a file to the blobstore . After it uploads the file , it gets the file key and calls a Bean that updates the xml by adding a node whose text-content is the key. public class UploadImagesToAisle extends HttpServlet { /** * Handles the HTTP * <code>POST</code> method. * * @param request servlet request * @param response servlet response * @throws

问题 Is it possible to have objects stored in a data structure for the duration of an App Server's uptime? Basically I want an EJB that interfaces with this Data Structure, but does not require a full fledged database solution. As an example I made this dummy animal object: package com.test.entities; public class Animal implements java.io.Serializable { private static final long serialVersionUID = 3621626745694501710L; private Integer id; private String animalName; public Integer getId() { // TODO
