Hi, I have created a report with ireports 2.0.4 and I want to run it from my webapplication (tomcat6 - jdk1.6) I get the following error, looks like the jasper reports compiler uses a pre jdk1.5 compiler. net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. Cannot cast from boolean to Boolean value = (java.lang.Boolean)(false);//$JR_EXPR_ID=8$ <------------------------> 2. Cannot cast from boolean to Boolean value = (java.lang.Boolean)(false);//$JR_EXPR_ID=8$ <------------------------> 3. Cannot cast from boolean to Boolean value = (java.lang.Boolean)(false);//$JR_EXPR_ID=8$ <------------------------> 3 errors Thanks in advance
