Hi, I know now that I should compile the java file first. I've tried using javac EvaluationScriptlet.java, but I got 8 cannot find symbol errors. I suppose that this is because the compiler cannot find the classes referred in the file, so I'm supposing I should specify some path to the compiler. As I'm using Mac OS X, I've tried the following: javac -classpath /Applications//TIBCO Jaspersoft Studio 6.0.1.final/configuration/org.eclipse.osgi/bundles/41/1/.cp/lib/jasperreports-6.0.0.jar EvaluationScriptlet.java But still got the same errors? How should I compile the scriptlet If I don't want to install a java IDE? Thanks
