How can you check if a file exists before including/importing it in JSP?

Question

Assuming that requestScope.importMe is expecting a path to a JSP file

Answer 1

Put it in a c:catch tag. It will catch any thrown Exception for you.

    


    Error: ${e.message}

I must however admit that I don't like the c:catch approach. It's abusing exceptions to control the flow. If you can, rather do this job in a servlet or JavaBean instead with help of File#exists() (and ServletContext#getRealPath()).
