FAQ Section: General
  1. What are Poseidon's system requirements?

    Poseidon for UML is written entirely in Java and therefore is platform independent. It runs on almost any modern personal computer. To successfully start and run Poseidon for UML you need the following:
    • Java 5 is strongly recommended for Linux, Mac OS X, and Windows platforms when running Poseidon for UML. While it is possible to use Java Runtime Environment or Java Development Kit. JDK 1.4 or higher, errors may result. Poseidon for UML will not run with JDK 1.3 or older.
    • A computer with reasonable memory and CPU power. For memory, 512 MB is recommended, more is helpful. For CPU, a Pentium III or equivalent is the recommended minimum.
    • A specific operating system is not required. Poseidon for UML is known to run on Windows 98, 2000, NT, and XP, on Linux SuSe 6.X, 7.X, Red Hat, and MacOS X. It has been predominantly developed and tested on Linux and Windows. However, on Windows platforms performance is known to be superior due to a faster Java environment.
    • For Mac OS X, you need the latest Java update. These are the specific requirements:
      Mac OS X 10.2.x (Jaguar): Get Update 1 of Java 1.4.1. Also, change Poseidon's Look and Feel to Alloy - the Aqua Look and Feel produces problems like not opening dialogs.
      Mac OS X 10.3.x (Panther): For Java 1.4.1, Update 2 is recommended. Furthermore, you should also use the Alloy Look and Feel. A typical problem symptom is that no dialog appears when you click 'Open File'.
      Mac OS X 10.3.x (Panther): For Java 1.4.2, any Look and Feel can be used.
      Mac OS X 10.4.x (Tiger): Tiger includes Java 1.4.2, any Look and Feel can be used. You can also use JDK 1.5.
