The JBuilder Plug-in requires JBuilder 5.0 or higher. See the section called "System requirements" for the basic requirements to run Jalopy.

The Plug-in comes as an executable Jar Archive (Jar) that contains a graphical setup wizard to let you easily install the software. Wizard installation is recommended and explained in detail in the section called "Wizard Installation".

If you would rather install the Plug-in manually, you have to decompress and copy the appropriate files into the different application folders. To decompress the contents of the installer Jar, you can either use the Jar tool that ships with your Java distribution or any other software that can handle the ZIP compression format (e.g. 7Zip or WinZip).

If you're upgrading from a prior version and want to keep your settings, first copy or rename the current Jalopy settings directory to match the version number of the new release. For instance, if your current settings directory is "C:\Documents and Settings\John Doo\.jalopy\1.0.4" and you're about to install Jalopy Help, either copy the directory contents or rename it to "C:\Documents and Settings\.jalopy\John Doo\Help". Wizard installation can perform this step automatically.

Make sure JBuilder is not running and remove any prior Jalopy Jar files from your JBuilder extension folder. The JBuilder extension folder is located under the root directory of your JBuilder installation, e.g. "C:\Program Files\JBuilder\lib\ext". Remove all Jar files starting with "jalopy-".

Now decompress the contents of the installer Jar file into a temporary directory and copy the two Jar files "jalopy-Help.jar" and "jalopy-jbuilder-Help.jar" from the temporary directory into the JBuilder extension folder.
