NetBeans no longer generates a JAR file for the code that it used to

Two years ago, I wrote a simple Java download applet developed using NetBeans. When I first got into "Clean and Build", then, and some time later, it worked perfectly. It runs through the build process and creates a JAR file that I could then upload to my web server, and the applet worked fine.

Now that I’m back and made some minor changes to this applet, it no longer creates a JAR file when I click “Clean and Build”. The actual code changes that I made are so small that I can guarantee that they will have nothing to do with it (literally just changing the contents of several lines). I know that since I originally built this applet, my NetBeans have been updated several times (now I am on version 6.9.1), so I wonder why the new versions now somehow do not work.

I don’t know if this helps, but this class is "self-signed" (on the "Web Launch" tab of the project properties), and below I turned on the output of the "clean, canned" panel at the bottom of NetBeans. I noticed that he says jar:, and then says nothing, but misses the right to BUILD SUCCESSFUL. I suppose something should happen between them?

Well, I'm not sure why this gave me this problem, but I found a solution. The solution was to simply delete and then re-create the entire project from scratch, and then try to compile again. I assume that NetBeans has updated the way to create manifest files or something like that with different versions, and it was suffocating in an older version.
