¿Alguien sabe a que se puede deber el siguiente error al compilar un proyecto en kawa?

Error executing a JAVA program. Please check the following -
1. JDK is installed and jdkbin is in the system path or it is set under Options/Directory in Kawa.
2. If you are trying to run an app please make sure the main class file is properly identified under Kawa.
3. If you are trying to run an applet please make sure the main HTML file is properly identified under Kawa.
Please refer to Kawa documentation on setting main class file or main HTML file.
