Hi, there

I just about to use the Jasper Report. when I try to compile my first simple .xml file, I got an error I really have no idea. code is like this:

public static void main(java.lang.String[] args) {

try {

long start = System.currentTimeMillis();

JasperCompileManager.compileReportToFile("first.xml");

System.err.println("Compile time : " + (System.currentTimeMillis() - start));

System.exit(0);

} catch (JRException jre) {

jre.printStackTrace();

}

and error said:

End event threw exception
