Hello, I understand the good example. Is it possible to set customizer class at runtime? Background, I can't set a customizer class in ireport because the java code from my application will be scrambled. So, jasperreports cannot find this customizer class in classpath. So, I have to set customizer class dynamically at runtime. Perhaps, is there a way to realize it with scriptlets? Or how can I set the class in my java application? Thanks for help
