How can I dynamica...

Hi, Consider the scenario of a typical webapp with JSFs on the front and ejb3, with Hibernate as JPA provider, talking to backend database such as mysql, etc. The main user actions are login and mostly CRUD operations (minus any D(elete) operations).

The last time I looked at web applications, the consensus seemed to be Struts/J2EE. Now, it looks like Spring MVC/J2EE or Struts/J2EE are both viable solutions. Is this generally correct? Or is Spring MVC now the consensus choice over Struts? We have at least one guy who has worked with Struts before and wants to go with that. I'm more f...

Ok so there are lots of nifty little technologies included in Java EE. When one learns SE, where should they go from there? I think what I'm looking for is more abstract/high level technologies that pertain to EE. I want to learn more and it seems to be difficult to find a book to transition into EE from SE. Where should I go from here? ...

I'm doing this by reading the contents of the file into a by byte array, then binding it to JNDI as follows. getInitialContext().rebind("customers_datafile", byteArray); This works fine, but the binding is lost when th...

A friend and I are building a fairly complex website based on java. (PHP would have been more obvious but we chose for java because the educational aspect of this project is important to us) We have already decided to use JSF (with richfaces) for the front end and JPA for the backend and so far we have decided not to use EJB3 for the bu...

I'm thinking something in lines of drupal multisite, where every site should have it's folder with themes, plugins and various static files. It turns out it's not quite easy to do with Java: classes must be in one place, tag files in other, static files in third, only jsp files can go wherever. classes and tags can be packed in jars, but...
