But when I attempt to read the same file with using the same class and the same method fr...

I know anonymous classes save typing, if it comes to implementing Listener and similar stuff. They try to be a replacement for some usages of closures. But what does the community think about the value of these language-feature? Does it make sense and you use it regularly? Makes the saved typing the code clearer, more understandable and...

Our code uses a lot of system properties eg, 'java.io.tmpdir', 'user.home', 'user.name' etc. We do not have any constants defined for these anywhere (and neither does java I think) or any other clever thing for dealing with them so they are in plain text littered throughout the code. String tempFolderPath = System.getProperty("java.io.t...

The application has to interact with a series of web services which are not really all that greatly designed, and don't offer much abstraction in and of themselves - basically there is a web service ...
I'm preparing a maven2 web project for continuous integration. I use the maven cargo plugin to automatically deploy the WAR to Tomcat6x before running integration tests. My code depends on some system properties which are set with MAVEN_OPTS=-Dfoo=bar. Unfortunately these properties are missing when the application is deployed to Tomcat...

I'm a highly skilled Java dev contemplating learning iPhone development. Mac only dev aspects aside, how much of a leap would learning the mobile application stack be?
