Hi friends this is my situation: here i am going do app for a college, there may be any no of colleges and each college may have any no of blocks. i have a jsp where i display all the details of blocks in row wise(this is a view block details page) and there will be some provision to modify any row( means that block details). >From there i transfer to blocksModify page in which she can modify any details. Problem is: My modify blocks form has some text boxes and some select bokes i am getting the text box values,but for the select box the all ready assiged college name should display from the rest of the options . i am not getting this
i am using the same form bean for both listing college details in select box
and displaying the rest of the details
this is my modify antion class
