(3) CustomCommand.java File

Note:- If any security check application is to be created in the struts 1.3 or higher then org.apache.struts.chain.commands.AbstractAuthorizeAction is to be extended but in case of previous versions the RequestProceesor's method processRoles() is to be overridden to check the security setting of the user.

package com.visualbuilder.command;

import org.apache.struts.action.ActionServlet;
import org.apache.struts.chain.commands.AbstractAuthorizeAction;
import org.apache.struts.chain.contexts.ActionContext;
import org.apache.struts.chain.contexts.ServletActionContext;
import org.apache.struts.config.ActionConfig;
import org.apache.struts.util.MessageResources;

import javax.servlet.http.HttpServletRequest;

public class CustomCommand extends AbstractAuthorizeAction {
// ------------------------------------------------------- Protected Methods
protected boolean isAuthorized(ActionContext context, String[] roles, ActionConfig mapping) throws Exception {
    // Identify the HTTP request object
        ServletActionContext servletActionContext = (ServletActionContext) context;
        HttpServletRequest request = servletActionContext.getRequest();

    // Check the current user against the list of required roles
    if(request.getParameter("user") != null && request.getParameter("user").equals("admin") ){
        return (true);
        }
    // Default to unauthorized
    return (false);
    }

protected String getErrorMessage(ActionContext context, ActionConfig actionConfig) {
        ServletActionContext servletActionContext = (ServletActionContext) context;

    // Retrieve internal message resources
        ActionServlet servlet = servletActionContext.getActionServlet();
        MessageResources resources = servlet.getInternal();

    return resources.getMessage("notAuthorized", actionConfig.getPath());
    }
}

Note:- Rest all the same as the previous composablerequestprocessor example for the application.

Output:-

Note:- If the role admin is entered only then the submit action gets called otherwise the following exception comes to the screen.
