I have a situation where I want to extract some information from some very large but regular XML files (just had to do it with a 500 Mb file), and where XSLT would be perfect. Unfortunately those XSLT implementations I am aware of (except the most expensive version of Saxon) does not support only having the necessary part of the DOM rea...
I'm trying to work in Eclipse as much as possible without a mouse. I cannot find a key binding for starting and stopping servers quickly in Eclipse WTP (Web Tools Platform).

Preface: I'm not a java developer. I have a question about Tomcat / jBOSS and other java application servers. Where are sessions (session data) stored?

Hi; We have an application which creates many sockets which belongs to its thread, By design if this application somehow fails, all threads stop which is not wanted. So to overcome this issue, each thread must be separated from the main application, if one of the threads fails, the other ones should be running. One thing in our mind is t...
I've replaced the Java internal ImageFetcher with an own implementation using ImageIO. Some image renderers of our software, which use these images, now draw anti-aliased scaled images instead of non anti-aliased. The only change is the source of the image, which are now BufferedImages instead of Toolkit-Images. The question now is, whe...

Dear All! I use Hibernate in an extension-like server-side application, and I put my binaries to the Extensions folder of the server application. The problem is, that if I run the server, the root folder is the root folder of the server application, and not the root of the binaries. Thus, Hibernate searches the config file in that folde...

The JUnit integration with eclipse is very nice. However, I would like a feature to be able to generate a quick report from the Unit Tests. It is possible to do so when running a headless build (and my nightly build is configured to do so), but sometimes I want to generate a report from the UI. Is there anyway to do this? command line...

Question - is there a way to introduce different configuration sets within the project and then compile slightly different code based on those?
