Vergil Web Start Downloads

Web Start is a product from Sun that uses the Web to download applications.

Click on the links below to install different versions of Ptolemy II on your local machine. These Web Start installers do not include sources, so users who want to write their own actors should install from source rather than installing these versions.

These downloads contain signed jar files so that Ptolemy II can access local files on your machine. The Ptiny Sandbox version is more restricted than the other installers, the Ptiny Sandbox version runs in a Java sandbox, which allows Ptolemy II to read files from the local machine, but is not as permissive as the other installers. Thus, the Ptiny Sandbox should be used for testing models that may have security issues.

Notes

Netscape 6

If you are running under Netscape 6, then the links above may state that you need to install Web Start from Sun even if you already have it installed. The reason is that the Java Script code fails to detect Java Web Start under Netscape 6.

A quick test is to click on one of the Vergil downloads and if you have Java Web start installed, either:

  • the Java Web Start splash screen should come up and the download should start.
  • or you should see a window that asks if you want to download the file or start up javaws. Click on Open using javaws.exe and then OK, and the Java Web Start splash screen should come up.
  • The Java Web Start FAQ at http://java.sun.com/products/javawebstart/faq.html#11 says:

    What are the supported browsers? JavaTM Web Start supports primarily Internet Explorer 4 or higher and Netscape 4.X. However JNLP files can be launched from any browser if the mime-type association is done correctly. Please note that JavaTM Web Start uses the browsers settings and may launch a browser to show a URL these may/may not work with unsupported browsers.

    JavaTM Web Start works with Netscape 6. However, you will manually need to register JavaTM Web Start with NS6. This is done in the Navigator/Applications section of the Navigator/Helper Application section. This will be done automatically in a later version of the JavaTM Web Start installer. back to top
