Hello,  
you probably use Java Runtime Environment (JRE) only to run the graph. When you want to run graph, that uses custom java source file (as in-line source or as link to external file), you need the tools.jar, that is available in Java Development Kit (JDK) (see [Chapter 3. System Requirements for CloverETL Designer](http://www.cloveretl.com/documentation/UserGuide/topic/com.cloveretl.gui.docs/docs/system-requirements-for-designer.html)).
