The Sun Documentation for DataInput.skipBytes states that it "makes an attempt to skip over n bytes of data from the input stream, discarding the skipped bytes. However, it may skip over some smaller number of bytes, possibly zero. This may result from any of a number of conditions; reaching end of file before n bytes have been skipped i...
Does anybody have experience of a decent J2SE (preferably at least Java JDK 1.5-level) Java Virtual Machine for Windows Mobile 6? If you know of any CLDC VMs, I'm also interested because even that would be better than what we currently have for the platform. ...
Can you recommend a Java API to use with a desktop application (i.e. J2SE not J2ME) that will, perhaps, work with the underlying operating system's Bluetooth stack to give access to Bluetooth functionality and devices? ...

I'm planning to work on some hobby Java projects. I've done some small-scale projects, so I'm familiar with the language itself and building a GUI with Swing. I'd like to make my work a little less ad-hoc and perhaps find some tools that might be useful out in the real world. NetBeans now comes bundled with the Swing Application Framewo...
I am reading books on middleware, Spring, Hibernate, etc., and am wondering myself why the developer invented a new name, i.e. "enterprise edition" for Java "web" or "internet" libraries? As I have a quite individual mindset, "enterprise" edition sounds almost like "socialist" edition... what do I need to know to differentiate better? ...

I'm writing a J2SE (Note, not JEE) application using Hibernate, and I need to provide a different connection to Hibernate for each thread of execution. These connections must be pooled, and each one has at the very least different authentication and, possibly, a different JDBC URL. The connections will be re-used (as can be inferred fr...

Calling some pre-defined methods on specific objects (e.g. to dump their state). Monitoring JVM health, especially memory usage. Preferably access all o...
Suppose I want to implement an application container. Not a full-on JEE stack, but I need to provide access to JDBC resources and transactions to third party code that will be deployed in an application I'm writing. Suppose, further, that I'm looking at JBossTS for transactions. I'm not settled on it, but it seems to be the best fit f...

I have a Vector < String >. Now i want to store those Strings in database. But i have one "but"! The program user mustn't install anything else except J2RE, he will just copy program to his computer and run. Does java has such kind of database? P.S.
