i succeeded in making 6.3 web example run in tomcat replacing following piece of code in project web.xml file:
<servlet-mapping> <servlet-name>javax.ws.rs.core.application</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> for servlet configuration code(taken 6.2 web example):
<servlet> <servlet-name>vrpshowscheduleservlet</servlet-name> <servlet-class>org.optaplanner.webexamples.vehiclerouting.vrpshowscheduleservlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>vrpshowscheduleservlet</servlet-name> <url-pattern>/vehiclerouting/showschedule.png</url-pattern> </servlet-mapping>
