JSP Error (original) (raw)

Hi, I've this JSP page that use a Collection to get the attributes' values. There is also a try/catch method in the code, which cause the JSP to be displayed as a blank page instead. I had wanted the [%=CM.getCourseID()%] and etc to be displayed. I believe that there is an exception hence causing the "system" to not display the items I want. I've tried looking through the codes but couldn't figure out where I went wrong. Can someone help? Thanks in advance.
