Spring Security (née acegi) integration str ategy?
In general, when planning to implement Spring Security for authentication, what is generally considered the best way to do so? 1) Implement the app completely with Wicket Security (wasp/swarm/hive) and then add in Spring Security? 2) Start with Spring Security and Wicket Security from the start?

Spring injection not working
I believe (though I'm clearly wrong in that belief) that I have everything properly configured to allow spring injection along the lines of: import com.foo.dao.UserDAO; @Spring private UserDAO userDAO; Meaning that for a bean defined in the applicationContext as . . . bean id=UserDAO class=com.foo.dao.UserDAO property name=entityManagerFactory ref=entityManagerFactory / /bean . . . I don't have to do anything else to utilize the bean. There is an added complexity in that I am using interfaces for the DAOs, ie. UserDAO implements IUserDAO. I've tried using different combinations of interface and dao, like the following import com.foo.dao.IUserDAO; import com.foo.dao.UserDAO; @Spring(name=userDAO) private IUserDAO userDAO; No matter what I've tried, userDAO remains unitialized. I have to resort to the following to get hold of the DAO... ApplicationContextapplicationContext = ((WicketApplication) Application.get()).getContext(); IUserDAOdao= UserDAO.getFromApplicationContext(applicationContext); Anyone have a guess at what I'm not doing correctly? I should note that in the main application class, the init makes the following call . . . addComponentInstantiationListener(new SpringComponentInjector(this)); And the entity manager is defined as follows . . . bean id=entityManagerFactory class =org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean property name=persistenceUnitManager ref=persistenceUnitManager/ property name=persistenceUnitName value=NetConfPU/ /bean -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hmm, Google is not being helpful. Is there a way to contribute CSS when a Panel is added to a page?

IE., I have UserDetailsPanel.java, UserDetailsPanel.html, and UserDetailsPanel.css. If I include the panel in an AjaxTabbedPanel(), with UserDetailsPanel.java containing a HeaderContributor.forCss() pointing to UserDetailsPanel.css, the rendered page does not contain the css link. Frankly, this is what I would expect, given that the page header has already been rendered.

I have to admit, I'm a little anal about clearing all warnings in my apps. What would an appropriate model be for the above PasswordTextField()? Models seem to be the most poorly exampled Wicket feature, in that examples of Models rarely tell one why they are needed and what role they perform. It's generally, here's an example to make your code work. Clearly, in most cases the model contains the data for the markup. But what would that data be for a PasswordTextField()?

It looks as though this is some subtlety (or brokenness) to GlassFish and Toplink. If I deploy my Wicket app as a module of a Java Enterprise package, it all works as expected.

Buehler? Packaged resources
OK, I asked about this earlier, but maybe the question didn't make sense. Asking another, and perhaps better, way: What problems do packaged resources address? I'm unsure as to why I would encapsulate resources in the package, rather than using them as I normally would via the WEB-INF tree. It seems as though encapsulating them would present a problem with separation of concerns, in which one team might be focusing just on presentation (eg. CSS, etc.) while another handles just the Java code. Using packaged resources would seem to require that the presentation people have access not only to the sources, but also to the dev platform to rebuild the package just to test CSS changes. -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The filter route sounds like want I want, as I would prefer to keep as much of the bookkeeping as possible out of the application logic. -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
OK, more JPA questions
There doesn't seem to be one recommended way to inject/use JPA-based utility archives in Wicket. It looks as though most of it is based around Spring, which is fine, yet adds another app layer. I've generated a tiny Derby db using the JPA facilities provided by MyEclipse. The sources can be found at: http://nedron.net/JpaTest.jar A binary library was created, including the default generated persistence.xml file and can be downloaded at: http://nedron.net/JpaTest-bin.jar I think more people than just me would find it useful if someone could use this extremely simple database in a simple, single page Wicket app. Note that I have zero problem using this type of library in a standalone Java app, and given that I'm relatively new to Wicket, I don't want to go to a bunch of effort only to find that I've gone about it the wrong way. Basic questions... Do I need to get hold of the com.foo.jpa.JpaNet.EntityManagerHelper in the main WicketApplication class and then serve that out to pages and panels as needed? The question here is, do I need EntityManagerHelper transaction wrappers around my DAO operations? Or is that handled auto- magically by some other mechanism (JTA)? I guess what I'm really getting at is, what is the recommended way to use the library directly without extracting it? All of the examples I've found so far include the dao/etc. along with the app code, so there is no clear indication as to how a third- party java library is used in Wicket(/Spring). And many examples and much of the documentation is remarkably framdibulous, along the lines of What is session managed? Session managed is not container managed. What is container managed? Container managed is not session managed. I've gotten myself pretty confused on this, as you can tell. ;) -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JPA suggestions?
I have a data driver package built around JPA and an Entity Manager Factory (javax.persistence.EntityManagerFactory). This is currently used by a couple of standalone applications and works well. What is the best way to leverage this package in the context of a Wicket-based web application? IE., how best to instantiate the factory (if necessary) and/or use the DAOs. Should this happen at the wicket application level, or somehow page/panel-based?

It is equivalent to the old PolicyFileHiveFactory and should be used instead if you are using 1.3.1 code. Odd. I'm using 1.3.1-SNAPSHOT that I grabbed today (jar files) and there is no SwarmPolicyFileHiveFactory class in it. Not a big deal if I can just swap in the old PolicyFileHiveFactory.

I give, anyone have a simplified (standalone) Acegi example
I'm adding Acegi support to a Wicket project, but have been completely unable to get all the pieces correct. One of the main problems is that there appears to be no standalone example available. The acegi- security examples are awful, since all thirty of the samples are mixed with each other and re-use components, needlessly complicating each example. IE., there's no way to see what is actually required for a specific example. The online guides (eg.http://wicketstuff.org/confluence/display/STUFFWIKI/Swarm+and+Acegi+HowTo ) refer to existing mixed examples without providing a full sample. Has anyone seen an Acegi+Wicket example that is: 1) Targeted at implementing Acegi in Wicket 2) Contains all the sample sources in a self-contained tree -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
TestingAuthenticationToken and AbstractAuthenticationToken
Using bits of the examples provided in wicket-security, I have the
following method define in AcegiLoginContext...
private AbstractAuthenticationToken token;
public AcegiLoginContext(AbstractAuthenticationToken token) {
this.token = token;
}
Again, following the examples, I call the previous method from my
login page as follows
LoginContext ctx = AcegiLoginContext(new
TestingAuthenticationToken(username, password,
getAuthorities(username,
password)));
However, the compiler (and NetBeans) complains that
AcegiLoginContext(TestingAuthenticationToken, ...) isn't a valid
method. NetBeans suggests creating the method. But given that these
are drawn from the (presumably) working examples, what is the issue?
TestingAuthenticationToken extends AbstractAuthenticationToken, so
shouldn't it be acceptable as input to
AcegiLoginContext(AbstractAuthenticationToken token)? My brain is so
twisted around trying to find the relevant parts of the example that I
must be missing something.
I feel like Dr. Thorndyke from High Anxiety, falling into a swirling
morass of interleaved code. ;)

Status of acegi/wasp/swarm?
We use acegi for one purpose, and that is to authenticate and authorize (AA) against our corporate SiteMinder server. We have existing Spring-based applications that successfully auth against SiteMinder via acegi. We're starting a new project and are planning to use Wicket. It looks as though one currently has to use some Spring bridging to inject acegi into a Wicket application. Are there plans to replicate the functionality of acegi as it relates to AA? Basically, is there, or wlll there be, a means for me to authenticate/ authorize/etc against something like SiteMinder without having to slide in bits of Spring to do it? -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
