hello,
I have HashMap.. {11=AA, 22=BB, 33==CC}.In hashmap, 11,22,33 are keys and AA, BB, CC are values.In these values(AA,BB,CC),each value has ArrayList. For example AA = {Testing1, Testing 2,Testing3}. BB = {Result1, Result2, Result3}. CC = {Success1, Success2}.
In jsp, in first dropdownlist, I want to set key of HashMap{11,22,33}. In second dropdownlist, I want to set values of HashMap{AA, BB,CC},
Finally, I want to know is when I select the key 11 of keys{11,22,33}, I want to get the value of {Testing1, Testing 2,Testing3} of AA. And so, when I select key 22 , I want to get the value of BB = {Result1, Result2, Result3}. And when I select key 33 , I want to get the value {Success1, Success2}of C.
So, Please help me.
