Upgrader is a simple tool that enables Java developers to add software upgrade capability into their applications. An upgrade process typically involves replacing the old version of the binaries with a new version of the binaries and performing data upgrades. It may also need to perform changes to the directory structure. The data upgrade outlined above may involve changes to the configuration files or database. This tool provides a framework which application developers can use to keep track of changes to the application. Every time there is a change in the database schema or configuration files, the application developers can create a "patch" script and add it to the "patch list". The Upgrader tool may be bundled with the application and is typically invoked during the installation and upgrade processes. When it is invoked, it determines the current patch level of the system, determines the patch scripts that need to be executed, sequences the patch scripts, and applies them.
MockInject is a library that supports accurate injection of your mock objects (either manually written or generated). Supported injection points are constructor-calls or method-calls. The injection-points can be defined by using a simple EDSL. It uses ByteCodeInstrumentation to inject your mocks, but you needn't have any knowledge about BCI or JavaBytecode, just the EDSL.
Skwish is a fast, simple, lightweight Java library for storing blobs on the file system. It allows multiple concurrent readers and writers, provides all-or-nothing write semantics, and is designed to survive abnormal, unclean shutdown. Skwish is a structured implementation of storing all blobs in a single file to save on file system I/O. Skwish is premised on the proposition that blob storage ought to be orthogonal to the task of indexing. It is meant to be a clean and simple store on which some other index can be built.
CrossFTP Server is a professional FTP server for multiple platforms. It offers a high-performance, easily configurable, and, most of all, secure-enabled FTP server. Its main advantage is that it is very easy to get started by novice users, and meets advanced users' requirements as well. It supports user virtual directories, write permissions, idle time-out, and upload/download bandwidth limitations. You can monitor all user activities. Both upload and download files are resumable. A database and LDAP can be used to store user data. "MODE Z" is supported for faster transfers.
Jim (Java Image Manager) is a program for managing your personal images (photos, etc.). While Jim is really easy to use, its tagging technology is quite powerful. A plugin system makes it easy extensible with new technologies. It runs on several operating systems (including Windows, Linux and many more); all you need is a Java Runtime Environment.
