1.)I need to set my java variable value in session.And want to get this session over Coffee Script.

Example: I have Bubble chart Screen.I am returning bubble size from java Spring Controller to Coffee Script.I need to create bubble different- different Size.I have no of Audience Segments,Each segments has different reach,I will find the max reach from higher segment,And on the bases of higher reach,i will make conditions,if reach greater than 100 than bubble size will be 50.Then set the bubble size variable in session.

My Question IS:How I can get the session value from java controller to Coffee Script.

  1. You can write your JS in JSP(not a clean approach, will be difficult for maintanence)
  2. Store the bubble size in a hidden variable and access that variable in JS

will work?
