Installing Ladybug


Ladybug is a JavaTM application and requires version 1.1 or greater of the Java Virtual Machine (JVM). If you do not already have Java, install Java now.

New Version Available

Click here to download new java .jar file.

NOTE: If you have not previously downloaded ladybug, you must follow the directions below first.

After downloading and unzipping the new .jar file, replace the previous version of ladybug.jar already downloaded. Running ladybug then should give a version number of 0.81.


Once you have Java support, select your operating system below for installation instructions:

Windows 95/Windows 98/Windows NT 4.0

3. Unzip into the folder you created in step two. If you have an unzip program installed, you should be able to do this by double-clicking on If not, download and install an evaluation copy of WinZip.

1. Create a new directory for the Ladybug application (e.g. ~/ladybug), and then change to that directory. To do this, type "mkdir ~/ladybug" followed by "cd ~/ladybug".

2. Download the Ladybug application and save it as ladybug.tar.gz in the directory created in step one.

3. Unzip ladybug.tar.gz into ladybug.tar by typing "gunzip ladybug.tar.gz".

4. Untar ladybug.tar into the directory you created in step 2 by typing "tar xvf ladybug.tar".

5. Execute the file named Ladybug to start the application.


1. Download the Ladybug application. Depending on how your system is configured, this file may uncompress automatically. If so skip to step 4, otherwise save it as ladybug.sea.hqx.

Other Operating Systems

1. Download the Ladybug application. It is available in zip, gzip, and tar formats.

2. Create a new directory for the Ladybug application.

3. Uncompress the file you downloaded in step one into the folder from step two.

4. In order to start Ladybug, the directory from step two must be in your classpath. The class to execute is ladybug.ui.MainWindow. For example, if your JVM is called 'java' and you are in the Ladybug directory, then the command to start Ladybug would be: "java -cp . ladybug.ui.MainWindow". Note that this command may vary depending on your operating system and JVM.

5. You may want to create a script to automate starting Ladybug. The script should consist of the same command that you typed in the previous step. The method to create a script depends on your operating system.
