Thanks Ronald. Anyway, i have managed to solve the problem, easier than i thought: i deleted activiti-kickstart/WEB-INF/lib/servlet-api-2.5.jar and kickstart boots fine now.
kind regards,
david

hmmm… Remarkable… Tomcat says it is ignoring the jar but it only starts working when it it realy not there… Sounds like a bug in Tomcat, but please file a jira issue to have the jar file removed, since it should not be included in the first place.

I've marked the servlet-api as scope "provided" on trunk for kickstart, so it won't happen in the next release:


<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>servlet-api</artifactId>
            <scope>provided</scope>
  </dependency>
