Question

I have started to look at Hudson as a replacement for CruiseControl. I would like to use it to monitor external jobs as well. I have tried to follow the advice on this page: Monitoring External Jobs

When I run this command:

java -jar hudson-core-1.309.jar

I get this error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/servlet/http/HttpServletRequest
        at hudson.EnvVars.initMaster(EnvVars.java:197)
        at hudson.EnvVars.(EnvVars.java:192)
        at hudson.Main.getHudsonHome(Main.java:71)
        at hudson.Main.run(Main.java:61)
        at hudson.Main.main(Main.java:53)
Caused by: java.lang.ClassNotFoundException: javax.servlet.http.HttpServletRequest

Answer 1

Add servlet.jar to the executing classpath. hudson-core-1.309.jar is built to run in a web container and thus doesn’t have that included.
