Here I have misspelled 'setBigDecimal' method, so it would not be able to generate class file - xx_ibeCCtdMenu.class. But on front end (iStore Customer UI) it would just give blank page. Catch block can not handle this type of error.
To find exact error, I have to get Apache Log (which take time to submit internal request in our org) or compile xx_ibeCCtdMenu.java file from _pages directory (there are so many unrelated excpetions).
I know this type of exception is handled well in R12.
Appreciate your feedback if could help me to find way to handle compile-time exception in jsp without going to apache log or manually compiling.
