Requirements: JRE or JDK 1.1.8 or better (java.sun.com). Recommended: 1.4.1 or higher. (It is best to get Sun's Java VM; Mesquite does not run on some third-party virtual machines.)
Instructions: Download and decompress one of the files above. It will create a directory called "Mesquite_Folder" in which all the relevant files reside. The main class file is mesquite.Mesquite. To start Mesquite you can use jre or java. For instance, on a Linux box I've used, I have a small shell script that resides in my directory (/home/wmaddisn/) that has the following lines:
jre -cp /home/wmaddisn/Mesquite_Folder mesquite.Mesquite
On some systems the java virtual machine is started by "java" instead of "jre", and thus the command would be:
java -cp /home/wmaddisn/Mesquite_Folder mesquite.Mesquite
By executing this shell script, I get Mesquite running. A dialog box commenting that Mesquite is still in beta stage will appear, then a window with the Mesquite logo. Once Mesquite has finished loading, go to the File menu to open a file.
If the current user directory is not the Mesquite_Folder, and Mesquite has not been run before, Mesquite may ask you to find the file "manual.html" which resides in the Mesquite_Folder/docs/mesquite/ directory. This will help Mesquite find and remember where its files are.
Mesquite attempts to place windows in particular places on the screen for ease of use, using standard Java calls. Some window managers override this, resulting in haphazard placement of windows. You may need to change your window manager if this sort of thing is happening.
