More brain flatulence
I have a colleage who is getting the old AbstractMethodError when trying
to deploy his first Struts app -- an app that is running in other
environments successfully. Apparently our plugin won't load.
Here is a snip from the stack trace during deployment:
16:06:44,238 ERROR [Engine] ----- Root Cause -----
java.lang.AbstractMethodError:
BestAssetsPlugIn.init(Lorg/apache/struts/action/A
ctionServlet;Lorg/apache/struts/config/ApplicationConfig;)V
at
org.apache.struts.action.ActionServlet.initApplicationPlugIns(ActionS
ervlet.java:963)
at
org.apache.struts.action.ActionServlet.init(ActionServlet.java:447)
at javax.servlet.GenericServlet.init(GenericServlet.java:211)
at
org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.
java:1019)
at
org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:86
2)
I had him check to make sure there are no old struts jars lying around
on the system. I can't figure out why the app will deploy in all
environments but his; we have the same versions of everything . . .
What am I forgetting?

You are right on. It turned out he had an older struts jar file lying
around. The scary thing is, it was lying around inside another web app
archive. I thought there would be a sandbox between the two -- but, my
head hurts from thinking about it anymore. Problem solved.
Thanks,
Erik

The init() method signature for the PlugIn interface was changed from:
init(ActionServlet, ApplicationConfig)
to
init(ActionServlet, ModuleConfig)
in Nov 2002 in between the Strust 1.1 beta 2 and Strust 1.1 beta 3 versions.
Also the stuff in initApplicationPlugIns() method in ActionServlet was
factored out into the initModulePlugIns() between Beta 2 and 3 but it looks
from the stack trace its using the old version.
I think its picking up a struts jar which is pre Struts 1.1 Beta 3 - but
your app was developed with the Struts 1.1 release version. If thats true
he's either deployed the wrong struts.jar or has an old version hanging
around.
