What do you mean by "contains all S2 files"? What libraries are you deploying?

From the stack trace it looks like you've deployed the REST plugin, which is almost certainly not what you want if you're not using it--the "create" method is the default method called by REST plugin form POST submissions.

If you're not actually using a plugin you must *not* deploy it; it may have additional library dependencies or alter the way your application works.

[prasad kakani]

These are the jar files,being deployed..

commons-beanutils-1.7.0
commons-collections-3.2
commons-fileupload-1.2.1
commons-io-1.3.2
commons-lang-2.3
commons-logging-1.1
ezmorph-1.0.3
freemarker-2.3.13
json-lib-2.1-jdk15
ognl-2.6.11
spring-test-2.5.6
struts2-convention-plugin-2.1.6
xpp3_min-1.1.3.4.O
xstream-1.2.2
xwork-2.1.2

[David Newton]

There's no reason it would be trying to call a "create" method without the REST plugin.

I'd try cleaning your deployment and physically verify you're not deploying REST.

How did you resolve this issue? I am getting the same error

Given that the last post on this thread is from 2009 and I don't think we've heard from David or Prasad since, you would be better off creating a new topic with all your relevant details.
