Food safety wise, 2 weeks is far too long to reprocess. 2 weeks is a long time for the botulism bacteria to reproduce and produce toxins.
Quality-wise, your beans will probably be terribly mushy after reprocessing.
Your chances of getting botulism are pretty small, but the consequences are very serious. I personally wouldn't risk it. If you do decide to risk it, thoroughly boiling your beans 10 minutes after opening the jar and immediately before eating will kill a lot of the bacteria and toxins.
