CONFIGURE YOUR SYSTEM

For most 2D plotting, Javapeño does not require any special configuration.   3D plots require a lot of memory.  Java, by default, does not allocate enough memory for its virtual machine to have more than a few (if any) 3D plots open.  To fix this, please follow these steps:
  1. For Javapeño in application mode:  Just run the bat file/shell script provided with Javapeño.   If you still have problems, then you may need to alter the bat file/shell script.
    1. Open the bat file/shell script in your favorite text editor (Windows users open it with Notepad)
    2. Edit the portion that starts with "-XmxNUMm", where NUM is a value.
    3. Increase the value of NUM.
    4. WARNING:  Entering too large a value for num will prevent Java from starting.
  2. For Javapeño in applet mode:
    1. Windows:
      1. Open Control Panel and double-left-click on the Java icon.
      2. Click on the Java tab.
      3. Click on the View button in the Java Applet Runtime Settings.
      4. Add (or modify) "-XmxNUMm" to the Java Runtime Parameters field (without the quotes).  NUM should be the amount of memory to give to Java.  The m after NUM means megabytes (or million bytes).
      5. WARNING:  Entering too large of a value for NUM will prevent Java from starting.
    2. Mac:
      1. Open Finder.
      2. Double click on Utilities.
      3. Double click on Java.
      4. Double click on J2SE 5.0
      5. Double click on Java Settings.
      6. Add (or modify) "-XmxNUMm" to the Java Applet Runtime Parameter field (without the quotes).   NUM should be the amount of memory to give to Java.  The m after NUM means megabytes (or million bytes).
      7. WARNING:  Entering too large of a value for NUM will prevent Java from starting.
    3. Others
      1. Launch ControlPanel from the Java JRE bin.  The JRE bin should be located at <Java_Installation_DIR>/jre/bin.
      2. Click on the Java tab.
      3. Click on the View button in the Java Applet Runtime Settings.
      4. Add (or modify) "-XmxNUMm" to the Java Runtime Parameters field (without the quotes).   NUM should be the amount of memory to give to Java.  The m after NUM means megabytes (or million bytes).
      5. WARNING:  Entering too large of a value for NUM will prevent Java from starting.
