TDDC03 Projects, Spring 2005 Improved Policytool for Java Permission Management

By David Krzystek and Irene AnggreeniSupervisor Almut Herzog and Irene Anggreeni


Java platform allows users to specify permissions for code from various sources, which are represented by a Policy object. The Policy implementation is configured by a static ASCII policy files. A policy file is basically a simple text file, which can be composed via any text editor or via graphical policytool utility, that comes with Sun’s Java. We addressed the question of improving policytool. We started a survey of the tool to make a list of problematic domains, especially regarding usage by novice users. We found some major drawbacks which are the graphical user interface, the missing help and the integration with other relevant tools. We put effort to solve the mentioned issues by redesigning graphical user interface, implementing a new tool based on the new design, and adding more helper functionality. Our suggestion for future works on the tool is to put more effort to increase the usability for novice users, not merely features. 1
