i'm trying to execute a java class from service task, in eclipse all goes right with no errors and correct value but when i run it on explorer i got this error " invocation of method componentEvent in org.activiti.explorer.ui.task.TaskDetailPanel$4 failed ", during my tests i found that is making error from method getdata() in class request_execution but why i didn't know.
in this class "request_execution" the method getdata() is reading from excel file and returning an vector containing the data inside it.
any help ?
