I have had 'success' in two different states concerning traffic tickets and jurisdiction. I did this by submitting the challenge on the record, before the court dates. Going into open court gives jurisdiction, unless the challenge is already on the record and the appearance is a special appearance. Once the challenge is on the record, the answer and proof of jurisdiction must also be on the record. The judges know this, and if they act without the answer on the record, they act outside of their jurisdiction and anything they do is not judicial and immunity is lost. However, neither case was dismissed, the file was simply misplaced and forgotten.
