I have set Project language level as 5.0. So I can use the thing like List in my Java files and without any problem when running. But when I put List]]> into my JSP file and open this JSP in the brower, an exception occured, saying:
Unable to compile class for JSP An error occurred at line: 28 in the jsp file: /Reporting/reporting.jsp
Asking me to use -source 1.5. ... is not supported at -source 1.3.
What does it mean? How can I setup it?
