Problem With Execute and Wait Interceptor

[Arpit Gadle]

Hi...

I am trying to add a page which informs the user that processing is going , if request processing takes more than 15 sec(see struts.xml snippet using execute and wait interceptor).

The issue is that execution time take by Department action, is same as specified in delay parameter. But if I don't use execute and wait interceptor,
the execution of Department Action takes around a 1 second.

struts.xml

<interceptors>
            <interceptor name="checksession" class="com.gtmteleshopping.hrms.interceptor.CheckSession"/>
            <interceptor name="clearcache" class="com.gtmteleshopping.hrms.interceptor.ClearCache"/>
            <interceptor-stack name="some_stack">
                <interceptor-ref name="defaultStack"/>
                <interceptor-ref name="checksession"/>  <!-- My Custom Interceptor For Cheking Valid Session -->
                <interceptor-ref name="logger"/>
                <interceptor-ref name="timer"/>
                <interceptor-ref name="execAndWait">
                    <param name="delay">15000</param>
                    <param name="delaySleepInterval">1000</param>
                </interceptor-ref>
            </interceptor-stack>
</interceptors>
<action name="department_add" class="com.gtmteleshopping.hrms.action.muster.Department" method="addDepartment">
            <interceptor-ref name="some_stack"/>
            <result name="input" type="redirect">department.html</result>
            <result name="invalidsession" type="redirect">invalidsession.html</result>
</action>

Department.java

public class Department
        extends ActionSupport
{
@SuppressWarnings("CallToThreadDumpStack")
    public String addDepartment()
    {
        try
        {
            DepartmentDao departmentDao=new DepartmentDao();
            int userId=Integer.parseInt(sessionMap.get("userid").toString());
            departmentDao.addDepartment(departmentPojo,userId);
            if(!successFlag)
            {
                resultFlag="error";
                successFlag=true;
            }
        }
        catch(NumberFormatException e)
        {
            System.out.println("Caught NumberFormatException In Department.addDepartment()...\t"+e.getMessage());
            e.printStackTrace();
            resultFlag="error";
        }
        catch(Exception e)
        {
            System.out.println("Caught Exception In Department.addDepartment()...\t"+e.getMessage());
            e.printStackTrace();
            resultFlag="error";
        }
        return resultFlag;
    }
}
