Estoy diseñando un reporte donde me presenta la siguiente excepcion, al igual que otros compañeros que ya han preguntado algo similar, dentro de jasper funciona con normalidad pero cuando hago la subida al servidor deja de funcionar.

Hello Jaspersoft! I'm having the same issue while running my Java program to generate a report, i tried to use iReport to build the report but i faced some issues, so i used Jaspersoft Studio-6.20.6, but when i try to run it from my java application, i get this error (this is the full error log , in case it is helpful) :

Thanks! And my apologies in advance , in case i'm not following all the procedures that might relate to the posing of issues.

I solved it, it looks like version compatibility issue since in my project libraries  i included the "jasperreports-5.6.0.jar" (which was missing this class: "ReportExpressionEvaluationData.class") though i was using Jaspersoft studio 6.20.6 to design the report, so i managed to find the correct "jasperreports-6.20.6.jar" file which contained the previously missing class and included it in my libraries instead of the other one. Thanks !
