I am trying to upgrade struts 2.3 to 2.5.3, I downloaded the package struts 2.5.3 and replaced the old lib folder with struts 2.5.3 lib folder, I also added jQuery pluggins 4.0.1 version, when I run the project I get error of velocity Manager, how can I resolve the issues.

Tried with various jquery-plugin and jquery-grid-plugin versions. It's not resolved!
