one more question

I can not run ireport 5.6.0 in win7. Should I set something?

[hozawa]

Yes, switch to Jaspersoft Studio. iReport is due to end of life next year. Shouldn't be using it now.

one more error, 

this morning I try to set the report data from HashMap, 

the error change to 

 

net.sf.jasperreports.engine.JRException: Error compiling report java source files : I:Java SAPSecondJasperreportFirst_1416963786573_878040.java I:Java SAPSecondJasperreportFirst_tableDataset_1416963786573_878040.java

 

I have no idea about those files.

 

Anyway, 

 

Exception in thread "main" java.lang.ClassCastException:[Lnet.sf.jasperreports.engine.type.CalculationEnum; cannot be cast to[Lnet.sf.jasperreports.engine.type.NamedEnum; at net.sf.jasperreports.engine.xml.XmlConstantPropertyRule.<init>(XmlConstantPropertyRule.java:47) at 

 

How can I fix those two question?

Please help.

Thanks.
