In my last poker session I had a set of Jacks and my opponent re-raise me 100€! What should I do???

Let's take the hand from the start: My opponent named "hero" raised pre flop 10€ from middle position...

I "GLadiaTOM" normally raise with a pair of Jacks, but I wanted to mix my game and I decide just to call having position to my opponent!

The Big Blind calls 10€ to...
Flops open AJT with two diamonds, "hero" bets 10€, I "GLadiaTOM" raise with my set of Jack 35€, Big Blinds folds and "hero" re-raised me 100€!!!

What should I do now?? Can I fold my set? My opponent could have QK and a straight or a set of Acces!... Or a set of Tens... Or a flush draw... Or a flush draw and gutshot or even open-ended straight draw with a hand like 89 diamonds...!

After his raise to 100€, I must decide for my hole stack (198€). "Hero" was loosing money and I decided to push all in hopping that he is a underdog!

My opponent "hero" puts another 98€ and calls my all in! Did I play good or not?? What's your opinion?
