Narrative:

We were inbound to jax on V267 (my student and myself). We had flight following and had been handed off to jax approach. We were approximately 20 NM from crg VOR and jax approach asked us if we were ready to start a descent. We advised yes, but would have to deviate to the west to avoid a cloud layer below us. Approach granted the deviation and advised to go to at or above 2000 ft. We descended to 2000 ft near the st john's river. We could tell that we could not maintain cloud clrncs and descended to 1800 ft and called to notify jax approach. The controller approved. A few mins later we realized that we were in NAS jacksonville tower's airspace. We called up jax approach and asked for assistance with the class D airspace and got no response. I had the student take a northeast heading to take us out of the class D airspace. A few mins later jax approach called (we were near the large antennas southwest of crg) and gave us a vector to jax. Nothing was mentioned by jax approach about the deviation into the class D airspace.
