Make sure you load all package in pom.xml?

[kevinMintnick]

On the left side of the idea editor, can see the loaded packages, such as jfinal's.

But still unable to compile

[kevinMintnick]

Is it convenient to provide specific development environment? Such as JDK version, development editor

[w703710691d]

this package in jfinal-2.2.jar，have you find this file？

[kevinMintnick]

Thank you very much for your answer. The problem has been solved.

[kevinMintnick]

However, why can't I add questions in the background?

[w703710691d]

you may don't have perrmision to access problem file see the var Data Directory in background info page , tomcat should have perrmision to write in those dir。 More information, please see tomcat log :)
