I'm using number of java files as common in different ADF projects, I want to archive them in jar file so I can import this archive file from any new project to use the java libraries in the project, I tried create it in jdeveloper but no luck.
Thank you for any advice,
You can use the following article to understand the way.
jar cf jar-file input-file(s)
But still you can zip a file using windows zip utility or winzip and rename it as a jar file. It is not official but it works.
