问题 Whenever I am running my xhtml. It is giving me the following exception. The value of statusindex object is 5. I am using JQuery for lazy scrolling,so when my xhml page getMoreStatusList calls getMoreStatusList function, it is giving me an index out of bound exception. There are 26 status updates in the database so index out of bound exception makes no sense to me. 1) Code public List<Status> getMoreStatusList() { FacesContext context = FacesContext.getCurrentInstance(); HttpSession session =

问题 Problem description: Theren are two subsystems. One is a web based Java EE application and the other a Cognos reporting tool. Currently, both these applications provide individual login pages that allow the users to perform their activities, as per the roles defined in the system. Java EE users can directly login to the Java EE application using its login page. Similarly, the Cognos users can login to the Portal using its login page by supplying their intranet ID credentials. There is a

问题 I'm in the process of writing unit tests for a JEE5 web service. The behaviour of the web service depends on the attributes set in the web.xml file. I'm wanting to therefore split my web.xml into a constant part and a part that is changed around inbetween test runs. To see if it's actually possible, I've tried to see if I can split out the welcome-file-list attribute. Using some instructions I found I've come up the following: web.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app

问题 In a regular Web Application, I can assign a chain of Filters to various paths for aspects such as Authentication, Authorization, Errors, Logging and more. The advantage is that I write servlets to focus on core functionality without worrying about infrastructure aspects. I can write orthogonal, cross-cutting Filters to authenticate, authorize, etc. Then I can weave them in web.xml. Looking at web.xml is enough to assure me that there are no holes in my application. Is this possible in JAX-RS

问题 How to check if Glassfish DAS is running programmatically even if it is deployed on local machine or remote machine? Using Java6 回答1: I have found a way to check if DAS is up other than Linux script. With this way it does not matter if both my application and DAS are at same machine or each installed different machine. public static boolean isUrlReachable(String host) { String URLName="http://"+host+":4848"; boolean isUp = false; try { HttpURLConnection.setFollowRedirects(false);

问题 We are one application in a larger environment and a client for some data interface, using Websphere MQ 8.x. Our application is a Java EE application running on a WildFly 9 which uses a resource adaptor ( wmq.jmsra.rar ) which is deployed together with the EAR file in the same AS. We interact with the MQ Server in both directions. So we have on the one hand some MDBs (which are due to historical origins still in EJB 2.x format without annotations) listining to some queues and which are

问题 I am trying to implement single sign-on between 2 Java EE applications. Both these applications share the same registry - LDAP.

What changes do I have to do in my application(s)? How do I test out the working of this? 回答1: An implementation of CAS will work for you, it is well documented and the changes needed to "CASify" your app are very
