I just upgraded from Struts 2.0.6 with Spring 2.0 to Struts 2.2.3. I am getting the following error on application startup. I have added the following jars. Please let me know if i missed something. In windows machine, my own validation methods are ignored and xworks validation gets control and throws a validation error. This does not happen in linux machine. 

 struts2-core-2.2.3
 struts2-json-plugin-2.2.3
 struts2-spring-plugin-2.2.3
 xwork-core-2.2.3
 commons-fileupload-1.2.2
 commons-collections-3.2

Now OpenSymphony has seen it's final days. All xml have to change the dtd to struts.apache.org.

xworks related DTD's have been uploaded on struts site "http://struts.apache.org/dtds/"

E.g. To fix your validation xml files.

Old way of validation DTD

<!DOCTYPE validators PUBLIC
        "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
        "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">

Replace with New validation DTD

<!DOCTYPE validators PUBLIC
        "-//Apache Struts//XWork Validator 1.0.2//EN"
        "http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd">

Try and see if above option helps.
