We're thinking of starting up a little bit of a "library" here at work for programming/development books, to have some shared books available as references. Any suggestions on titles to put on the list? We mostly concentrate on Java and web application development, using Spring, Web Services, SQL, etc. My thoughts so far: Effective J...

I am writing a Java application using SWT widgets. I would like to update the state of certain widgets upon a certain event happening (for example, updating the data model's state).

I am aware that the ods format is zipped...
We are using JAXB 2.x to generate data objects from a massive schema system (42 XSD files). That entire process runs fine, no problems there. But they deprecated (and removed from implementation) the entire JAXB validation framework, replacing it with the JAXP validation framework instead.

Hi I am having to run a breadth-first search in Java for an assignment. I have a 5x5 grid of tiles (24 in total - 1 tile is left 'blank').

To do this search, I have created an Arrayli...

Is there a good, strict date parser for Java? I have access to Joda-Time but I have yet to see this option. I found the "Is there a good date parser for Java" question, and while this is related it is sort of the opposite. Whereas that question was asking for a lenient, more fuzzy-logic and prone to human error parser, I would like a ...
