Question

Hi ,
I downloaded a bean who read data from excel file and put it in database, to implements in forms.
when the bean try to read number from xls, it's stops with message indicating mismatch in type.
i read source of the bean, i find that method used is getStringCell from apache poi api,
I take the source and i try to modify it, in order to read number from xls.
My jdeveloper10g is running with jdk1.4 so i add jdk1.5 to modify the bean.
i tune the imports library problems. and finally the program compile with this error message

Looks like the classes that you are using were compiled with a different JDK version.
Try using JDeveloper 10.1.3 - which has built in JDK 5.
