Run the following occurs during use jstl.jar package and standard.jar packet error:
“org.apache.jasper.JasperException: Unable to compile class for JSP”
Error reason: only in the jar package into a web-> into the WEB-INF-> lib.
Solution: to copy and paste into the jar package lib in src directory.
to sum up:
idea mechanism jar package under the WEB-INF directory is only valid at runtime, if the compiler package of jar, then you need to use the jar package into the src directory.
