I was trying to execute a simple program in IntelliJ IDEA as a static web project. I'm a newbie and I'm learning web development with Node.js. I took help from the official website of IntelliJ IDEA, but the error was same. Though, I configured the settings and Project structure also.


"C:\Program Files\Java\jdk1.8.0_91\bin\java" -Didea.launcher.port=7535 "-Didea.launcher.bin.path=C:\Program Files\JetBrains\IntelliJ IDEA 2016.1.2\bin" -Dfile.encoding=UTF-8 -classpath "C:\Program Files\JetBrains\IntelliJ IDEA 2016.1.2\lib\idea_rt.jar" com.intellij.rt.execution.application.AppMain ""

Exception in thread "main" java.lang.ClassNotFoundException: 
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(
    at com.intellij.rt.execution.application.AppMain.main(

Process finished with exit code 1

Please help me to sort out this problem. I'm digging out this problem since few days.

Is that supposed to mean something?

More specifically, at line 122 in file, you are trying to use a class of which your project cannot retrieve the definition.
We would need to see this line for further analysis.

When i execute the program, it says module not specified.

The error you are receiving here means when you are trying to run the class, IntelliJ is not able to find it.

To fix this, you need to add a .jar file to the classpath:

java org.somepackage.SomeClass -cp myJarWithSomeClass.jar

or if running on the command line you must add the dot operator: (.)

java YourSingleClass -cp .

Hope this helped!
