Hello Guys, I am new to Jasper Report. Recently I have installed JasperReport Server and can use it with iReport. But in all sudden, when I create simple report on my local machine using the datasource from the remote database, I received this error message. Few days ago I managed to use iReport and create reports without any problem. Without any changes, suddenly the problem arised so this puzzles me a lot. Here is the message details; I did searches for the solution on the Internet without any success. Thank you in advance. Appreciate your help.
