Hi, I recently migrated my project from mx9 to mx10 and also upgraded all modules to the latest versions. In doing so, I first removed all user libraries. However, I now realize that importing Excel files, also known as the Excel importer, is no longer functioning correctly and I don't understand why. Below is a part of the logging. Error in execution of monitored action 'RegularClientAction' (execution id: 1710775699690-12, execution type: CLIENT).NoClassDefFoundError occurred for class 'Could not initialize class org.apache.poi.ss.usermodel.WorkbookFactory$Singleton'. Please make sure the userlib folder of your project includes the correct library which contains this class. java.lang.NoClassDefFoundError: Could not initialize class org.apache.poi.ss.usermodel.WorkbookFactory$Singletonat org.apache.poi.ss.usermodel.WorkbookFactory.wp(WorkbookFactory.java:327)... etc. Can someone help me with this?
