WebSampConnector+FITS Demonstrator


Troubleshooting

Java 6

In order to run the demonstrator, you need to run Firefox with Java 6. If using a Mac you need to have at least MacOS 10.5 Leopard installed: MacOS 10.6 Snow Leopard has Java 6 by default. If using MacOS 10.5 Leopard, you need to do a software update: see this page

Temporary directory

The demo needs a temporary directory to store files. On Unix and MacOS, /tmp is used. On Windows, the user needs to create the directory C:\tmp first if it does not exist.

Java Policy

UPDATE: With version 8 of the applet we have a solution for that so the following is no longer needed!
If you experience problems where the spectrum is always the same and you see messages in the java console saying that the spectrum file cannot be created, that's a bug: the java applet can create the first spectrum file, but when called via JavaScript, it cannot do it anymore. The workaround is to create a $HOME/.java.policy file containing the following lines: 
grant codeBase "http://voplus.obspm.fr/-" {
permission java.security.AllPermission;
};
