I have used the above code in order to demonstrate the validation for struts2. The validation is not triggered , even if the validate fails , success page gets displayed. Kindly go through the code and suggest me the changes.

    Which S2 version ? You should use the new filter, FilterDispatcher is deprecated. Commented Oct 20, 2015 at 9:58

    Make sure that it is deployed also in the same location. Commented Oct 20, 2015 at 9:59

  1. Apply the new filter because the FilterDispatcher is deprecated;

  2. Change your wrong definition from

    <!DOCTYPE validators PUBLIC
    "-//Apache Struts//XWork Validator Definition 1.0.3//EN"
    "http://struts.apache.org/dtds/xwork-validator-definition-1.0.3.dtd">

    to

    <!DOCTYPE validators PUBLIC 
    "-//Apache Struts//XWork Validator 1.0.3//EN"
    "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">

As you can see in the Apache directory (http://struts.apache.org/dtds/) there are xwork-validator 1.0, 1.0.2, 1.0.3 but xwork-validator-definition is only 1.0, and is not the right one, according to the documentation.

Very weird. Can you please edit your question by updating the code according to the modification made ? DTD, new Filter etc... even if minified and with name changed, the code must be the same of your real code, otherwise you could avoid posting something critical to the problem without noticing. Also pay attention to constructors (there must always be a no-args one, implicit or, when another is specified, explicit) and getters/setters for variables with one letter lowercase and another capitalized eg "fBar" that Eclipse creates in a wrong way
Will do it and let u know
Andrea Ligios i have made the edits as suggested by you. Please go through it.
In JSP it is still name, not ename
