The Cottagers boss was hoping his players could put a slow start in the Premier League behind them in the opening Europa League group game.
But, having taken the lead through Andrew Johnson, they ended up having to settle for a third home draw this season when goalkeeper Mark Schwarzer was credited with an own goal.
The Londoners dominated their Dutch opponents for large spells of the game, but Jol felt it was the same old story as far as the outcome.
"I felt you can't do more than we did in the first half," he said.
"Everything went well. We pressed them at the right times and scored from that [period] as well. We played good football and the second half was probably different because we tried to force the issue.
"Then they had some space to hit us on the break and they did that a couple of times. That is the only thing. If you don't score goals easily enough then you still have to try to.
"Keeping our shape is a lesson we have learned for next time but the worry of course is four matches and three draws. I have to say in all those games we have been the better team.
"It is the same story. Against Aston Villa we were the better team, against Blackburn the same and now. Of course I cannot blame anyone because they did well but we have had to put a lot of energy in.
"With a game against Manchester City coming up [on Sunday], that is the only disappointing thing."
