Greetings, Reading the jira issue below, it seems that the developers believe this to be a Tomcat classloader issue. I know little (read: nothing) about classloaders, but a few observations I have using Google-fu:
1) Classloaders in Tomcat are "twitchy", and you may be stuck with this behavior. Unless of course you want to master Tomcat classloaders. 2) Servlet.jar missing or in 2 places can cause issues. 3) Struts core jar file in 2 places can cause issues. This looks like this is happening during a cleanup op (i.e., after you have re-deployed) so maybe it's trying to use a class it *thinks* it has but which has already been removed? I'm curious - any reason why you are not deploying using a war file? It might be interesting to see what happens if you deploy it that way. -Ty On Mon, May 17, 2010 at 3:16 PM, Emi Lu <em...@encs.concordia.ca> wrote: > The most similar question I could find is: > > https://issues.apache.org/jira/browse/WW-2921 > > But did not find any solutions? > > Someone knows the solution? > > Thanks a lot! > -- > Lu Ying > > > > > > On 05/17/2010 02:50 PM, Emi Lu wrote: > >> Hi Rebecca, Martin, >> >> Could you be having something going crazy with your build scripts or >>> something where the struts core jar isn't getting put in the right spot? >>> >> >> >> >> check to see if struts2-core-<version>.jar is located in >> YourWebApp/WEB-INF/lib >> >> Yes. it is there. >> >> Tomcat 6.0, jdk1.6, ant-1.6.2. >> >> If I restart tomcat, the error is gone. >> >> The error is shown only when I re-install source codes and did not >> reload tomcat. >> >> Some possible places that I should pay special attention?
