Cache Problem

[Amit M Tank]

Hi Friends,

I am not sure what could be the problem with this app. But same app works fine in weblogic. it might be a problem with Struts2 on Tomcat.

I have a simple webapp that provides user profile data to the user. The request parameter is the profile id that gets passed to the struts2 action which reads the data from the MYSQL server and sends it back to the browser using a jspx files.

When I invoke the url with param id=0 it works fine.

Example

http://localhost:8080/profile/profileFile.action?id=0

but when I invoke it with param=1 it sends me back the data for param=0 in the browser.

http://localhost:8080/profile/profileFile.action?id=1

When I restart tomcat and invoke url with param id=1 then it provides correct result. I put logs in the action file after and it prints correct(expected) results all the time, but it shows wrong result on the browser.



I deployed the same app on weblogic10.3 and it works fine all the time.


Thanks,
Amit

It's unlikely this is a Struts 2 issue per se; Struts does no caching on its own. Without the code/etc. it'll be hard to diagnose, though.

Here is the Action Class

  

package com.tank.matrimony.action;

import com.opensymphony.xwork2.ActionSupport;
import com.tank.matrimony.info.UserProfileInfo;
import com.tank.matrimony.service.UserProfileService;

public class ProfileFileAction extends ActionSupport {

    private static final long serialVersionUID = 1L;
    
    private UserProfileInfo userProfile;
    
    private int id;

    public String execute() throws Exception {
        System.out.println(" Calling to get Profile for Id " + this.getId());
        UserProfileInfo allProfiles =
            UserProfileService.getInstance().getProfile(this.getId());
        this.setUserProfile(allProfiles);
        System.out.println(" Got Profile " + allProfiles);
        return SUCCESS;
    }

    public UserProfileInfo getUserProfile() {
        return userProfile;
    }

    public void setUserProfile(UserProfileInfo userProfile) {
        this.userProfile = userProfile;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

}

  

When I do the System out it shows me the correct result(the one I want), but on the browser it sends me the same page for all diff "id"


Here is the jspx file which displays the page

I don't see anything obvious; sorry.
