my question is how do you make sense of a seemingly endless stacktrace? (really curious, it's some time since i did something in java) Another problem i had with java: most projects are impossible to understand by looking at the source code, as they tend to do things like Spring or EJB: with delayed loading where class names are specified in some configuration files - and it is often hard to figure out how the system is initialized. That leads to another question: Is it possible to learn about an unfamiliar java project from source code in this day and age? i mean they used to say that perl is a write only language; but enterprise java isn't very readable either.
