Software requirements

The eBURST applet requires that you have a recent version of Java™ on your computer (Java™ 2 Standard Edition). This is available as a free down-load from Sun Microsystems

To allow the Java™ applet to import and export files the ‘permission’ file needs to be downloaded and saved to your machine.

PC/Windows Users

You must save the document in the folder c:/documents and settings/your_username/. The file must be named .java.policy (note the ‘full stop’ before the word java).

Your computer may try and add a .txt extension to the file – you can stop this from happening when you save the file by ensuring that the ‘Save as type’ within Notepad drop-down menu is changed from ‘text document’ to ‘All files’.

After saving, open the folder and, in the ‘view’ dropdown menu, use the ‘details’ option to check the file type. It should be called a ‘Policy file’ and should be correctly named as .java.policy).

If there are several user_name folders within your documents and settings folder, and you are not sure which is the correct one, you can try putting the .java.policy file in the user_name folders one at a time, until you get the correct one. If the applet appears the file is ok and in the correct location. If the applet does not launch, or you get a query box asking permission to input/output data, the file is in the wrong place or saved/named incorrectly.

MAC Users

-Open a terminal window (This should open by default in your directory).
-Open a text editor then copy and paste in the java policy text listed below
-Save and exit your text editor , giving the file the name .java.policy.

To download the permissions file click here or alternatively copy and paste the following into a text editor and save as .java.policy in your folder as above.
