Hints on Java installation

Installation of Java can be a bit cumbersome and confusing, especially when you have never worked with it before.
Here are some hints and tips:

In short: you will need Java J2SE JRE to run AstroStack 3.

Java installation steps:

**) Opening a command terminal:
Windows 98 users: Start - programs - MS-DOS
Windows XP users: Start - All Programs - Accessories - DOS/Command
Mac OSX users: Applications - Utilities - Terminal

Java extension directory:

This is the place where Java programs find resources and libraries they need.
The best thing is to copy all jar files (astrostack3le.jar or astrostack3.jar and plugin ASP*.jar) to the Java extension directory, including all extra external libraries you may need.
The extension directory can be found in AstroStack in the General / Info tab. If more than one directory is listed (separated by ; or :) pick the first one.
After coping any jar file to it, you need to restart AstroStack (you can always start from the AstroStack directory where you unpacked the zip file).

Some Java terminology:



Memory issues

Reserving permanent more memory for AstroStack

Windows
In Windows Explorer select menu 'Tools/Folder Options .../File types'.
Look for Jar and select Advanced (see attached JARtype.jpg).
Look at 'application used to perform action:'
There is a line under 'application used to perform action' like:
"C:\Program Files\Java\j2re1.4.2_05\bin\javaw.exe" -jar "%1" %*
Now just add the memory option before the '-jar' part (use a space before and after the memory option):
"C:\Program Files\java\j2re1.4.2_05\bin\javaw.exe" -Xmx256m -jar "%1" %* and press OK.
This should give AstroStack permanently a maximum of 256Mb memory when starting it by doubleclicking astrostack3.jar, without having to use a DOS prompt.
You can change this value if needed (-Xmx512m for 512Mb etc). Preferably keep it below your physical RAM memory or the program could become very slow when using its given maximum.

Linux
  1. The quick-and-dirty method
    Start a terminal or console window
    Make sure you are in the AstroStack directory: type "CD Astrostack3" if necessary.
    Type: java -Xmx256m -jar AstroStack3le.jar
    This starts AstroStack with 256M of memory. Change the number if you need more memory. Do not enter a higher number than 70%-80% of the total real physical amount of RAM memory of your machine. So if you have 1Gb onboard, use 768m etc...
