Then put it in the plugin folder in the main eclipse directory and restart eclipse.

Make the settings as follows: windows ->perference ->general ->editors ->file associations, and select *class, then select Jadclipse Class File Viewer under Associated Editors, and click the Default button on the right to set it as the default.

Note that when set up this way, double-click some of the .Class files still can't be decompiled, because these class files don't have the source code attached, and in order to parse all class files, you need to do the following:

Under file type, select *Class Without Source, then click Add under Associated Editors, add JadClipse Class File Viewer, then select JadClipse Class File Viewer, and click the Default button on the right to set JadClipse Class File Viewer to *class without source.
