I'm trying to convince my providers to use ANT instead of Rational Application Development so anyone can recompile, recheck, redeploy the solution anyplace, anytime, anyhow. :P I started a build.xml for a project that generates a JAR file but stopped there and I need real examples to compare notes. My good friends! I don't have anyone c...
I'm currently trying to get into the Java EE development with the Spring framework. As I'm new to Spring, it is hard to imaging how a good running project should start off. Do you have any best practices, tipps or major DO NOTs for a starter? How did you start with Spring - big project or small tutorial-like applications? Which technolo...
I have seen two ways of implementing DAO-DVO design. 1) DVO are objects and DAOs are instantiated using factories i.e DAOs are also objects 2) DVOs are again objects but in this case, DAOs are classes which contain only static methods which accept DVOs to perform tasks. I was wondering which way is better and more scalable thanx in ad...
There are a couple of things that I am having a difficult time understanding with regards to developing custom components in JSF. For the purposes of these questions, you can assume that all of the custom controls are using valuebindings/expressions (not literal bindings). Although I'll gladly upvote those who give good explanations on...
A friend of mine is now building a web application with J2EE and Struts, and it's going to be prepared to display pages in several languages. I was told that the best way to support a multi-language site is to use a properties file where you store all the strings of your pages, something like: welcome.english = "Welcome!" welcome.spani...
Does anyone know if it is possible to restart a J2EE application (from the application)? If so, how? I would like to be able to do it in an app-server-agnostic way, if it is possible. The application will be run on many different app servers-- basically whatever the client prefers. If it isn't possible to do this in an app-server-agn...
ATG is a suite services built on top of J2EE which uses it's own proprietary flavor of ORM (like Hibernate but not), dependency injection (like Spring but not), and JSP tag libraries to offer and integrate services like customer profiling and targeting, e-commerce (shopping cart, billing, inventory, etc.), e-mail blasting, content manage...
In Jetty, if there is no deployment at '/' then the DefaultHandler displays a list of known contexts. This is very useful during development. Is it possible to configure BEA Weblogic to provide a similar convenience? ...
I'm trying to check, using an automated discovery tool, when JAR files in remote J2EE application servers have changed content. Currently, the system downloads the whole JAR using WMI to checksum it locally, which is slow for large JARs. For UNIXy servers (and Windows servers with Cygwin), I can just log in over SSH and run md5sum foo.j...
What are the best questions to ask when running a technical interview for a senior level j2ee developer? ...
I have a huge ear that uses log4j and there is a single config file that is used to set it up. In this config file there is no mention of certain log files but, additional files apart from those specified in the config file get generated in the logs folder. I've searched for other combinations of (logger|log4j|log).(properties|xml) and h...
What culprits are the most likely to cause a 404 resource not found error when a page in a given .WAR, autocreated by Sun's J2EE deploytool, is trying to load a Servlet in the same .WAR file? Eg: HTTP Status 404 - /MyServlet/MyServlettype Status reportmessage /MyServlet/MyServletdescription The requested resource (/MyServlet/MyServ...
If I have a Resource bundle property file: A.properties: thekey={0} This is a test And then I have java code that loads the resource bundle: ResourceBundle labels = ResourceBundle.getBundle("A", currentLocale); labels.getString("thekey"); How can I replace the {0} text with some value labels.getString("thekey", "Yes!!!"); Such...
I have an existing J2EE enterprise application to which I need to add auditing, i.e. be able to record CRUD operations on several important domain types (Employee, AdministratorRights, etc.). The application has a standard n-tier architecture: Web interface Business operations encapsulated within a mixture of stateless session beans a...
For a typical Web client -to- Servlet/WS -to- Business Tier (Spring or EJB) app, what are the trade-offs of approaches like remote RPC or messaging for Web (Servlet) tier to remote Business tier, aside from the basic sync/async aspects? ...
I currently am tasked with updating an XML file (persistance.xml) within a jar at a customers site. I can of course unjar the file, update the xml, then rejar the file for redeployment. I would like to kind these command line operations in a Swing App so that the person doing it does not have to drop to the command line. Any thoughts ...

Please guide me to some resources which tell me actually what java enterprise applications are, how they are different from normal java classes etc. Also which is best application server to use (on Li...
Hello, my employer just asked me to run a timed batch process in a J2EE websphere application they have running. It's supposed to run a certain class at 1130 pm everyday. I'm not very familiar with J2EE nor websphere server (or tomcat, in the develpment environment), and I've been digging around but all I've found is about the java time...

Has anyone found a usable JSP/Servlet hosting provider? Lunarpages offers JSP as an option, but the server they use (Resin 2.1) is poorly implemented, out of date, cantankerous, and is always running out of memory. There's javaservlethosting.com, but they apparently have a rather negative reputation for poor service. Myjavaserver.com is ...
