Thomas Vermaelen's own goal gifted the visitors, who had not won at Arsenal in 25 attempts, the lead after 65 minutes.
The Belgian went on to redeem himself when nodding in from close range with seven minutes left but the Gunners could not conjure up a winner.
Jol said: "A draw for us is a satisfying result. In the first half, we had 50/50 possession, with seven attempts on goal. But we could not play our football in the last 15 minutes. We tried to pass it and get it to the front players but to get three points, you have to do a bit more."
He added: "Arsenal had played a difficult game in the Champions League this week but you still have to work hard against them because they have a winning mentality and showed that in the second half when they were 1-0 down, they did everything to score.
"But with their form over the past six weeks, a draw is pleasing for us."
