I attend in process of designing JEE web application. It consist of: - backend module (EJB 3.0) - 3 web modules (JSF) Our application must be secure, so some colleagues claim that it must be splitted into two or more separate servers - backend in one server, webapps in other(s). In our case performance isn't a problem but this architecu...

I was told that this is possible if I create many threads, because Java threads uses memory outside of the heap. My java process is a server type program so there are 1000-20...

I can take the approach of leaving as a large Monolithic JSP file that takes params and adjusts it's behavior accordingly.

I want to take the data from a BytesMessage and pass is to a class that will de-serialize it. I'm running some tests to see if using Hessan for serialization is any better than Java Serialization. The Hessan classes take an InputStream to read from. The BytesMessage has no getInputStream() method so I thought I'd write a wrapper aroun...

I work on a social media monitoring system. We don't crawl the web ourselves, we get feeds from aggregators like Spinn3r. In most cases, the "blogs" that are nothing but pages of links to porn sites are filtered, but we'd like something in-house that we can train on a quicker time frame than waiting for upstream providers to make changes...
