Hello
i was trying to run old hibernate project on tomcat7 and got following exception . I THINK IT BECAUSE OF OUTDATED HIBERNATE VERSION (please correct me if i m wrong) as 3 and 4 version is out so i feel it will be big gap. please answer
1) Is following error because of outdated version
2) Is there any document or blog to start for 2 to 4 up gradation
3) Will struts 1.2.4 work efficiently with hibernate 4 or i need to upgrade it also
