There isn't very to see here since I haven't written much software as of yet. When I just started with Java I've written up a lot of small utilities to extend my experience with the language.
One of the first things which caught my attention when I started exploring was Java's native support for SSL. Using the keytool program you can create a private key and a certificate which you can then use to sign your programs. This information is usually stored in a file called "keystore", located your homedirectory. So far, so good. The keytool program can easily list the contents of your keystore but when it comes to copying private keys it doesn't work very well. So one of my first test projects was writing a tool which converted the Java keystore to a so called pkcs12 keybag so that it could be easily processed by openssl. This approach can help you to move a private key (and its certificate) to another keybag.
If you got Java installed (minimum version 1.5, also known as Java SE5) and your browser knows about the so called 'Java Webstart' you can download and start the first version of my program automaticly by clicking here. Things have changed a little in the mean time and while the first version was completely manually developed I decided to give NetBeans' GUI builder ('Project Matisse') a testrun. This resulted in a new version of the Keystore Converter which can be started here.
Keep in mind that this program isn't perfect yet. For example; there is no helpscreen present yet, and there is a limitation to consider when using Unix(-like) OS's; on Unix the keystore file is usually an hidden file called ".keystore" (no "") located in your homedirectory. But the default file lister doesn't show hidden files, so you'd have to type this filename out yourself.
As you may know by now I'm actively supporting a small IRC network called NekoNet which has been around for a year or so. One of the problems we faced were the tutorial sessions in the #class channel. We used to get the IRC services to perform this task through the use of a plugin but when the services evolved and the plugin was abandoned things halted with a grinding screech. So liking Java the way I do and just having discovered the PircBot IRC API I simply couldn't refuse trying to write something up myself. The result is NekoBot, an IRC tutorial bot which can be used to perform up to 3 tutorials in 3 different channels at the same time. You can grab the rar file for version 1.2 here.
