Go, no run, to see a lawyer in your area that is well versed in the Fair Debt Collections Practices Act. If it was barred by the statute of limitations the last time, it is this time and you may have a very good claim.
Many state's procedures will allow for a dismissal and the creditor can sue again. However, if the case was barred by the statute of limitations when the first suit was filed, the state procedure will not help.
You should go see a lawyer.
By answering this question, general information is provided and no attorney-client relationship is established. For specific inquiries, you should consult with experienced counsel in your area.
As stated by the other attorneys, do not try to handle this yourself.
You probably do have a good case against the JDB (harassment, FDCPA violations, malicious prosecution, etc.), but a competent, local collection attorney will be the best person to assess that.

Based on the facts here I would say that there are some FDCPA violations, but I would want to know more facts first. For example, is it the same company from before that is contacting you? They may have sold the debt off to another company that is now contacting you. Was the statute of limitations the basis of the dismissal? If not, was it a document production problem that they had?
