I’m making a new plugin for jdownloader an open source download manager. I’ve made the plugin in eclipse. I tried exporting the package as a jar file and placing it in the directory for plugins however jdownloader doesn’t recognise the new plugin.
I have noticed all other jdownloader plugins from other authors are in jar archive files including a manifest with java classes and their corresponding SHA1-Digest values. Does this mean i need my jar digitally signed? If so, how.
How can you find out if a digitally signed jar is necessary to work with a particular application? I have no intention of making it publicly available as it would be of no use to anyone but me.
