I use the rest-client to test REST APIs. It is basically just a .jar file, that is called via
java -jar rest-client.jar. The rest-client uses two file extensions, in my case
.rcq, to store data in files.
I want to let the explorer open
.rcq files with
java -jar rest-client.jar <infile>, however, if I configure it (via GUI) to use the JAR alone, it obviously doesn't work. I'd be fine with touching HKEY_CLASSES_ROOT for this, as well, but don't know the exact syntax.
By the way: It's WinXP.
