Re: S2 best location of application init params
If you're using Spring (and if you're not, now might be the time to consider it), I'd say make that a property of your application object that needs to configuration. That is, using your example, say you've got a class, TransactionLogger that needs "the home directory of the file system to which the application will write." Give it a property, loggingDirectory, and configure it with Spring, giving it a bean id of "transactionLogger". Then, add Struts 2's Spring plugin to your project (just include the JAR), define a method setTransactionLogger(), and Spring/Struts will automatically inject the TransactionLogger instance into your object. In your action, just call transactionLogger.logTransaction(foo), and there you go! Among the benefit of this approach are: 1.You can unit test your business object (TransactionLogger) without involving Struts at all 2. The business object could be re-used outside your Struts application 3. The configuration is only where it needs to be; in the business object itself. So you don't have to come up with some naming convention for your init-params, nor do you have to write tedious code to make the business object aware of the configuration. That is, TranscationLogger doesn't have to be tied to the Servlet API, nor do you have to write an initialization servlet that creates a TransactionLogger. This ventures off-topic from Struts 2, which should probably be your goal: your business objects should not be tied to Struts or the Servlet API.

Re: struts 2 action messages / action errors
Struts 2 allows you to style them, but using themes. Themes are both more powerful and more complicated than what Struts 1 offered. Before you dive into customizing a theme, see if you can style it entirely with CSS. You're best better is probably to "View source" in your browser to see the rendered HTML, noting the classes that the built-in themes use. Then, override these styles with your own stylesheet. Using the built-in css_xhtml theme (add struts.ui.theme=css_xhtml to struts.properties) will give you more flexibility, compared to the default theme (xhtml). If that doesn't give you the look you want, it's time to dive into themes. Themes are documented here: http://struts.apache.org/2.x/docs/themes-and-templates.html http://struts.apache.org/2.x/docs/extending-themes.html Mark Menard has provided an excellent tutorial on creating custom themes here: http://www.vitarara.org/cms/struts_2_cookbook/creating_a_theme On Oct 24, 2007, at 11:58 AM, Brian Relph wrote: Does struts2 handle the css-styling of action errors and messages the same as struts1?

Re: Where is struts-*.tld
It is very different, but I'd still encourage you to play with it. I've been using it for a few months (though I had played with WebWork before), and I love it. I've found it light years ahead of Struts 1.x, and not nearly as frustrating as Spring MVC. It's got a learning curve, like any framework, and some of the concepts (such as the interceptor) seem esoteric at first, but they grow on you, and begin to look more and more like a brilliant architecture the more I work with them.

Re: [FRIDAY] JPA War Stories?
I've been using JPA annotations with Hibernate for a while, but still using the Hibernate API (SessionFactory, etc.). Those are great, and I felt right at home with them after using XDoclet to set up Hibernate mappings for about two years before that. I'm just getting started using the Persistence API (with Hibernate, naturally), so it's too early for me to share war stories. So far, so good, though. While it may sound trivial, that I don't have to specify the individual annotated classes (or .hbm.xml) is a nice touch. Venturing slightly (more) off-topic, I recently switched from having my DAOs extend from Spring's HibernateDaoSupport, and using HibernateTemplate, to just going directly to the Hibernate API. Or, now, to the JPA API. I don't benefit from Spring's exception translation that way, but you know what? I don't think that really matters (in Hibernate 2, it was helpful, but the exceptions have are now unchecked). If the applications relied on Spring's DAO exceptions, this could make it harder to switch from Hibernate to JPA. Any JPA war stories related to such a switch?

Re: creating a dummy session object for unit testing
The session object is a simple Map, so creating it is easy.
First, you have to define an instance variable in which to store the
session, and second, you need to implement the setSession() method.
public class MyAction implements SessionAware {
private Map session;
public void setSession(Map session) {
this.session = session;
}
}
If most/all of your actions need access to the session, you may want
to define a BaseAction that implements SessionAware, and add a
protected method, getSession(). Or, you could make the session
variable protected (instead of private), but I prefer getSession().
In your unit test:
Map session = new HashMap();
session.put("key", value);
action.setSession(session);
String result = action.execute();
assertEquals(SUCCESS, result);
What the map contains are the keys and values your action expects.
These are the same things you'd pass to HttpSession.setAttribute
(String name, Object value). So, say you want to store a shopping
cart object in the session, you'd do:
session.put("shoppingCart", shoppingCart);
action.setSession(session);

Have you checked out the Bootstrap Tutorial yet? It gives you a great intro to Struts 2, and a bit of Maven 2 at the same time. http://struts.apache.org/2.x/docs/bootstrap.html Ian Roughley has put out a book, which you can download for free (though I'm sure he'd love it if you purchased a printed copy), called Starting Struts 2. http://www.infoq.com/minibooks/starting-struts2 On Aug 29, 2007, at 2:34 PM, sp4rc wrote: Thanks for the input. I think I will have to start with the total basics before moving on to struts. Anyhow I googled for any tutorials, sources I just got more and more frustrated, as I just dont know where to start. Has anyone a got starting point, link, etc. for me?

Re: ant, maven and creating war's
I haven't touched Ant in years, so I can't help you much there, but with Maven 2, it's as simple as running 'mvn package'. The POM itself says whether the project produces a JAR, WAR, or some other artifact, so package always builds the appropriate artifact for the project. For a web app, that is of course a WAR, for something else, it may be a JAR. For development, you might want to try using Jetty instead of Tomcat, because Maven 2 has a plugin that makes this really simple. Add the following to your POM: org.mortbay.jetty maven-jetty-plugin 6.1.5 10 implementation="org.mortbay.jetty.nio.SelectChannelConnector"> 7171 You can set the port to whatever you want (7171 in this example), just make sure it doesn't conflict with anything else you have running. Then, run 'mvn jetty:run', and a Jetty server will fire up. Nothing to install. Go to http://localhost:7171/ in a browser, and you'll see a link to your application.
