    private String fullname = "Ranjith";
    private String emailaddress = "Ranjith";

    @Override
    public String execute() {
//        System.out.println("session = " + session.isOpen());
        return "success";
    }

    public String getUsername() {

1) Include json according to your struts2 version from here

2) Your package should extends json-default as below

<package name="example1" extends="struts-default, json-default">
<action name="edituser" class="com.hyva.accounts.master.useraccountsetup.MasterUserSetUpActionEdit">
            <result type="json"></result>
   </action>
</package>

3)Check your action for json result like your action name in address bas http://localhost:8080/edituser

It will show json response to browser.

thanks for your replay this is what i am using struts2-core-2.1.6.jar and struts2-json-plugin-2.1.8.1.jar and i have updated my code please look at above. — user4135983, Oct 13 '14 at 06:05

Include Apache's commons-lang-2.x.jar.

Then, since major changes occurred in 2.1.8, be aware that mixing 2.1.6 with 2.1.8 stuff is really, really bad.

Use the same version for all your struts libraries. Struts-core, Struts-json, others if any (struts-spring-plugin, struts-config-browser-plugin, struts-junit-plugin, etc). All except struts-jquery-plugin, frremarker and ognl (that btw must be picked with respect to the right version as specified in Struts dependecies page).

Then it is fundamental trying to upgrade to the latest version (2.3.16.3), due to security issues (and other reasons). If you'll go that way, then include both Apache's commons-lang-2.x.jar and Apache's commons-lang3-3.x.jar (if only the latter isn't enough, because of legacy code). Since they're in different package, they can cohexist.
