I need to profile a java application for a customer. It's an eclipse/maven project, so I decided on using eclipse TPTP ( http://www.eclipse.org/tptp ). I tried to install eclipse TPTP through the update manager from a standard eclipse installation, but I gave up because of the unbelievable complex setup and downloading of dependencies w...
When using JDBC, I often come across constructs like ResultSet rs = ps.executeQuery(); while (rs.next()) { int id = rs.getInt(1); // Some other actions } I asked myself (and authors of code too) why not to use labels for retrieving column values: int id = rs.getInt("CUSTOMER_ID"); The best explanation I've heard is some...

Hi, Despite that the work of the guys from SUN with the Java core API is awesome, as they are humans, they are not infallible. I have read in several books some criticism about Some huge mistakes that (my guess) are still there for backward compatibility and legacy code. My question here is which ones do you know? As examples: Observa...
I have a large legacy system to maintain. The codebase uses threads all over the place and those threads share a lot of mutable data. I know, sounds bad. Anyway, don't answer "rewrite the whole application from scratch" or I'll vote you down :-) I have tried to run some static analysis tools on the codebase, but none of those seem to cat...
We are hosting a site for a client and they want us to include the header they have on their server into the pages we are hosting.

I have a lot of Java source code that requires custom pre-processing. I'd like rid of it but that's not feasible right now so I'm stuck with it. Given that I have an unfortunate problem that shouldn't have existed in the first place, how do I solve it using maven? (For the full story, I'm replacing a python-based build system with a ma...

Any recommendat...
