Except for the vision of Jesus himself appearing to Paul, and the Lord speaking to Ananias to go to Paul since he had seen Jesus, and the convinced 12 Apostles to the fact, and the Brothers in Tarsus and Jerusalem who were convinced, there is no scripture indicating that Paul actually met Jesus.
Of course, with that kind of evidence, I am convinced he did meet Jesus through a vision and his teaching was accepted by those who did know Jesus, so I would say that those who knew Jesus and Paul were in agreement that Paul preached what Jesus taught.
