How to use jquery and bootstrap with struts2 2.3.15

Question

I have on struts2 2.3.15 application with netbeans 8.1. I have used bootstrap and jquery 1.11.x . display works well but all the forms submits twice. If I remove the jquery.js file then form works well but ui fails. tried to use bootstrap plugins for struts2 but gives error. Caused by: Unable to load bean: type:org.apache.struts2.views.TagLibraryDirectiveProvider class:com.jgeppert.struts2.bootstrap.views.BootstrapTagLibrary - bean - jar:file:/D:/server/application/build/web/WEB-INF/lib/struts2-bootstrap-plugin-2.0.4.jar!/struts-plugin.xml:27:148

Thanks in advance.
