Tomahawk is a general-purpose applet for simple batch file processing. The real work of file processing is separated into a custom class called "weblet". By only modifying the weblet code, the applet could do a lot of different batch file processing tasks, e.g., image processing, album generator, word2text conversion, batch file uploading, etc. Because it's quite difficult to find a free tomcat jsp host, I have to embed several different batch file processing tasks into a general-purpose applet.
