Hi

I am working in a old project and implemented in struts old version.
I have to find that whether a particular action (project/dispense.do) is completed or not.

I am planing to have a session variable "isDispenseActionProgress" in start and end.

But I don't want to edit the action perform () method.
because there are many return mapping.findForward(""); are available in that method.


I tried the ServletRequestListener. It's working. But I feel this is very heavy in performance vice since it'll call every action call even jsp call also.

Is there are any other way to track this? like listener or any method to complete the thread.


Thanks

I am asking this for inquiry purpose.
because I have to find from existing flow in a complex Project.

I can make sure that,that method is called by somewhere. But couldn't find the place.

Hi

Is there are any way to identify the place from where the particulate method is calling in runtime?

thanks but did you try it , i mean where is your reference



This should work.
This is a general code.
rb.getString("NVFORMS").split(":"); is valid code.
But need to do the null check.

String[] s=null;
if(rb.getString("NVFORMS") !=null){
s = rb.getString("NVFORMS").split(":");
}

It would be rare to have any app used only by a single user, but that is in any case not a differentiating criterion - desktop apps can be used by multiple users, and web apps can be used by single users.

Desktop App
* Code will be in the every system.
* Need installation for every system


Desktop apps can access code running in an app server, so the client-side would mostly be GUI code (so the diagram you posted is incorrect): As to installation, something like JavaWebStart (JNLP) makes installation and updates very low overhead.

A big advantage of web apps is the wider availability of the platform - just a web browser, which is available everywhere already and independent of the OS, with no need for further client-side software (like specific versions of Java or .Net). If designed properly it's also much easier to reach mobile devices.

this is not mean , You can not choose desktop app...
I have mention that the good choice.

Desktop apps can access code running in an app server, so the client-side would mostly be GUI code (so the diagram you posted is incorrect)



This is something advanced. But I was explaining him the basic idea.
In your case, that diagram might be incorrect.


As to installation, something like JavaWebStart (JNLP) makes installation and updates very low overhead.



For the basic web application, we don't need any installation since web browsers comes alone with OS.
That's my Idea.

Yes this is correct.

super.calculateCost(newCost);



this method is not available in the super class.

Hi

This is dependent on your requirement.
If you want to choose multiple client - Server application. You can choose Web app
If single user only, You can choose Desktop app.

Desktop App
* Code will be in the every system.
* DB can be common server
* Need installation for every system

Web App
* Code will be in the server only.
* DB will be in common server
* No need any installation rather than browsers.
