Play: Lightweight Java-based framework, with Scala support available as an extra. very good for rapid prototyping, fast-feedback-loop kind of work. Embeds the compiler, so you just edit source code in place and pages get immediately updated. Learning curve is shallow. Wicket: Stateful Java-based framework, with Scala support available as an extra. Shallower learning curve into … Read more
Maybe it’s not a full answer to your questions, but maybe it might help you. The code being called when you do NOT use programmatic login, but a standard one is to be found here: org.springframework.security.ui.webapp.AuthenticationProcessingFilter I guess you were inspired by this in your code. It looks quite similar. Similarly the code executed when … Read more
I found that following these instructions helped with finding what the problem was. For me, that was the killer, not knowing what was broken. http://mythinkpond.wordpress.com/2011/07/01/tomcat-6-infamous-severe-error-listenerstart-message-how-to-debug-this-error/ Quoting from the link In Tomcat 6 or above, the default logger is the”java.util.logging” logger and not Log4J. So if you are trying to add a “log4j.properties” file – this … Read more
Some relevant differences as I see them: Tapestry uses a semi-static page structure, where you can work with conditionals and loops to achieve dynamic behavior. Wicket is completely dynamic; you can load components dynamically, replace them at runtime, etc. The consequences of this are that Tapestry is easier to optimize, and that Wicket is more … Read more
I think I’ve invested some time for both frameworks. I really like both because they bring the Swing-alike coding to web development. And I don’t know easier ones for me (although there is click but I don’t like the velocity templating thing) And yes, there are differences. I wont have to worry much about the … Read more
The security error is unlikely to break your page. It looks like the error is happening from within the YouTube frame, which means that in the worst case the content of the frame will be messed up. A frame/iframe from an external page cannot, under any circumstances effect the content of the parent document unless … Read more
The problem is not in your Spring annotations but your design pattern. You mix together different scopes and threads: singleton session (or request) thread pool of jobs The singleton is available anywhere, it is ok. However session/request scope is not available outside a thread that is attached to a request. Asynchronous job can run even … Read more
