Re: What's the rigth way to do it ?
Slimane, I think I now understand what you are asking about. Basically I think your understanding of the session bean is right. In web application, we usually put the session bean as an object in the http session. I think the following are what you may think when deciding which way to use: 1. Do you have an application supporting EJB? Say you do not have it, then you may have to use the http session to achieve this 2. How you want to view those string objects? Are they coupled with any EJB as the bean's internal state? If that is the case, it may be better to go into the bean. This is better from the OOD standpoint 3. Is either of them working? Yes. Technically both should be fine.

Date: Sun, 10 Mar 2002 12:22:10 +0100 Hi Bin, I think I wasn't clear enough. Because, that's exactly what I want to do ! :) I just want to have a session scope Object. So, let me reformulate my problem: I have, for example, 3 Strings. The contents of these Strings can dynamically change. These Strings contain different values between each user. So, normally you'll set that values into a cookie placed at the Client's computer. But I don't want to do that, so I was first thinking about a session bean. That bean would contain those Strings and will be instanciated for each user (am I wrong ?). So normally, a session bean will be perfect in that case, won't it ? But, if I understood right, the session bean is placed into the HttpSession object. So, why not place those Strings directly into the HttpSession object ? (using the getAttribute and the setAttribute methods) But, after a second thought, as I don't have only 3 (or 5) Strings to share (between all my Action classes) during a session of a user. I was thinking that maybe, placing those Strings as parameters of my Action classes would be sufficient. So between those 2 solutions, which one is the best ? And is there maybe a better solution ? Voilà, I hope that now I made myself clear (please excuse my poor English :) I also hope, I didn't tell to much stupidities (I'm just a newbie :) Any help would be greatly appreciated !

So I was thinking about setting all these objects using the HttpSession object. (using the methods getAttribute() and setAttribute()). But in a second thought, as there are only a few String that I need to share. I could easily pass them as parameters to my Action classes. So, I was wondering what's the right way ? If there's only a few Strings, isn't it easier to pass them as parameters instead of using the session object ? Thanx in advance for your replys.

Re: What's the rigth way to do it ?
Slimane, Passing parameters using query string is ok. There are some benefits you get get like user can book mark it and get back to the page later on easily. The problem with the query string is that there is some size limitation there. I do not remember the exact size of the string you can pass on. It might be something like 8k. A lot of populate site are using this to do it and some application use URL rewriting which basically is passing parameter by query string if the client browser disable the cookies. Hope this help.

Date: Sun, 10 Mar 2002 17:25:42 +0100 Bin, Thanks for your answer :) The fact is I don't have any EJB. So I think I'll just use the HttpSession object :) And about passing the strings as parameters* of my Action classes ? Was it a bad idea ? If so, why ? * What I mean by parameters is for example doing the following: A HREF=bla.do?param1=dohparam2=goshblabla/A where param1 and param2 are my actual parameters and then in the Action classes, I'll use the getParameter() method Thanks again, Slimane At 10:27 10/03/2002 -0500, Someone poor demented soul by the name of Bin Zhou presented us with the following text which may contain useless information.
