问题 I have some SOAP webservices build with JAX-RPC. These work fine. But as soon as I add a handler, I get an exception. When the binding is removed from the webservices.xml, everything works fine again. The weird thing is, the handler itself isn't included in the stacktrace of the exception. I also noticed, the init and getHeaders methods of the handler are called, before the exception is raised. The handler is added to webservices.xml with the following xml: <handler> <handler-name>My Message

问题 There is a webservice on some other server which I am calling in my Java Code. It responses only for POST method (there is NO GET method) available. This request / response works correctly while I implement the full method with request XML and call the Webservice, i.e. it works correctly. But requirement is --> there will be three webservice URLs (configurable from my Application by Admin User). First, I have to check whether the first URL one is connection or not. If Not connecting, then go

问题 I have successfully deployed a Java EE app to openshift with tomcat7. I deployed the war file and the welcome page loads but when my app tries to read an input .txt file to the application it can't find it. Any help would be appreciated. My input files (2) are in the /WEB-INF folder in my project in eclipse. This is my relevant code from my startup servlet: public void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // 11 lines of code setting

问题 I have a Java EE project that I will turn into a war file. When it runs, it will generate a log file, I would like the file to be generated at the same parent directory as the war file. For example, my war file is: C:\project.war then my log file's path would be: C:\log.txt But all I found was how to find resources inside the project. How can I find the parent directory of my project before it generates a log file? 回答1: You should not rely on paths like this. The WAR that you create may get

问题 My dev environment is: WildFly 8.1, CDI, EJB 3.2, JDK 1.7. App is packed as an ear archive (one ejb + one war) because probably it gonna have other web modules in the future. I'm struggling with a custom @InterceptorBinding type used inside my EJB stateless bean. @Inherited @InterceptorBinding @Target({ TYPE, METHOD }) @Retention(RUNTIME) @Documented public @interface DetectIntegrityConstraintsViolation { } @javax.annotation.ManagedBean // make it a CDI bean. @Interceptor itself should be

问题 I have to calculate in Java what is the number of the current day in the year. For example if today is the 1 of January the resut should be 1 . If it is the 5 of February the result should be 36 How can I automatically do it in Java? Exist some class (such as Calendar ) that natively supports this feature? 回答1: You can use java.util.Calendar class. Be careful that month is zero based. So in your case for the first of January it should be: Calendar calendar = new GregorianCalendar(2015, 0, 1);
