[OT] How to retrieve a session attribute in Applet
I need to access a session attribute in Applet. Since it can't be passed into Applet as a parameter from a JSP file, I need to figure out a way to retrieve it. Thanks for your inputs.

Re: Anyone still use the layout component ?
Thanks very much Craig for you response. To my knowledge, the Tiles and the component serve the same functionality but doing thing differently. I am not sure what your compatible mean here. In regarding of i18n, the Tiles forces us to use the a set of JSP files per locale approach while the one doesn't. We can't afford to use the approach since we don't have enough man power to maintain a large set of JSP files. I don't see why you are drawing this conclusion. The individual pages produced via Tiles can be localized by the same mechanisms as non-Tiles and non-Template pages (such as using the bean:message tag to look up localized text in a resource bundle). We use the JSTL fmt tag to retrieve locale messages/strings, but not the bean:message tag. Last time, that was about eight,nine months ago, we had spent a quite chunk of time testing out Tiles on localization. The Tiles didn't work with the resource bundle approach. In response of our question, the Tiles creator stated that the Tiles could be used in i18n with the different JSP files per locale approach. The problem, I recall, is that Tiles cachs a single locale region content of a JSP file in the server. When a user access the same JSP file with a different locale, what s/he gets isn't a page with the desired locale but the one cached on the server. I also had experienced different language regions shown up on a page due to the mechanism. I don't know whether this Tiles mechanism has been changed or not in the past some months. The problem we have with the component is the TC tag pool configuration must be false at TC 4.1 up to 5.0 beta. According to the TC online document, the cause very likely is on the tag implementation. We need to find out what need to be fixed. The Tiles implementation included in Struts 1.1, like all the other Struts 1.1 tag libraries, should run fine with tag instance pooling enabled. The component I indicated here is the layout component by David Geary, not Tiles. Get advanced SPAM filtering on Webmail or POP Mail ...

Re: Anyone still use the layout component ?
Thanks Ted for your response. What do you mean by compatible, however? To my knowledge, the two components do thing differently, although they serve the same functionality. In terms of an i18n solution, the Tile forces us to use one set of jsp files per locale approach, while the other one doesn't. We can't use the Tile, even though we like to since we don't have the manpower to maintain a large set of jsp files. We have no choice, but stay away from Tile. The problem we run into with the component is that the tag pool setting in the server configuration has to be false on TC 4.1 up to TC 5.0. The tag implementation seems not quite right somewhere in the component. We need to find out where the source is to resolve the issue. BTW, we had raised the Tile i18n approach issue before in this mailing list. The author argued (harshly) that is not a Tile issue. (Who's problem then?)

RE: JavaServer Faces
This question indeed has be asked before. JSF only covers the frontend portion of an application, namingly the V and C. The Struts addresses more development issues. An article on integration Struts and JSF recently appears on the developerWork(IBM) web (if my memory is correct). That is to say you can use the two together.

Where the plug-in configuration shall go? I don't use Struts, but Tiles
only. According to the document on tiles-documentation.war, the
TilesServlet shall be used, if my understanding is correct.

I start getting quite frustrated on this issue after a few days of
researching on the Tiles home page, Tiles Struts home page, Struts email
archive, the tiles-documentation.war, and google on Tiles. The whole
development is stop at this point.
I have read somewhere at the email archive: it is not need to process
the initialition if the definition is stored in a JSP file, which is the
case I posted my previous post.
I change the definition method, using a xml file instead. After having a
xml file and modification of web.xml, I get the logging message when I
start/reload the applicaiton:

Build the Tiles
Hi, all, I need to use the Tiles as a standalone component in my project. I am new to Tiles in less than on week. I follow the chapter 11, Developing applications with Tiles, of Struts in Action to set up Tiles. I run into a couple of problem and hope someone can give me a hand. The tiles.jar file I get from Cedric Dumoulln's site, which was built in the last Noverber. But the all common libraries are the most recent releases. I think the old build might cause those problem. After uploaded the rc1 source base, I only can see the Tiles installation, but not compiling and archive Tiles. Can I build Tile from the source? If yes, how I can do it? Thanks for your helps.

Re: RE: re. i18n
To my knowledge, there are two ways to set up locale. One is to use the container's
configuration setting for
application. The other is to have an application itself session locale attribute. The
Struts as well as the PetStore use the
second approach. The locale setting can be changed inside of the container by either
calling Config.set method for the
first approach, or reset the locale variable value,
session.setAttribute(org.apache.struts.action.Action.LOCALE_KEY,newLocale);
for the Struts case for the second approach.
The statement, ?locale is unchangeable during a session? is still not true even in
Struts. Does your code also
demonstrate locale resetting?

Vernon,
The last time I checked the Pet Store application does not use Struts. If
you look at the Struts source code you will find that the user's locale is
stored in session and is later used when reconciling which message resources
to use. Look at the processLocale() method from the RequestProcessor below
(very similar to the processLocale() in ActionServlet for 1.0.2).
Jeff,
It appears you are doing everything right. I think you're right in saying
there is something small that you're missing. You shouldn't need to change
any localization settings through Control Panel. The browser setting is
what is sent with your request. I'm sorry I couldn't be of more help.

Subject: re. i18n
I saw the following statement in today mail archive.
Also keep in mind that the locality is stored in session. This
means you
cannot switch languages while using the same session. The best way
to test
is by setting your language, close and reopen your browser.
This statement is not true. The Pet Store allows users change the locale
anywhere in the middle of session. You can
test out yourself by driving a demo version from
http://developer.java.sun.com/developer/technicalArticles/J2EE/deployathon3/
BTW, the locale information management, including changing locale method,
demonstrated in the latest version PS is
not the best way by today's standard. Take a look at JSP/JSTL articales on
onjava.com by Hans Bergsten.
Hope this helps.

A better practice: environment entry vs. initialization parameter?
A few of email addresses needed to be accessed from time to time in my current project. They can be definited either as initialization parameters or environment entries. I can see some pros and cons of those two implementations. Do someone have some experience with those two implementation for a heavy loaded application? Thanks for sharing your informaiton.

Re: Book Opinions
Nat, I am thinking about walking the opposite direction as you do. After playing about the Pet Market from Macromedia MX, I wish my Java Web application have the degree of rich UI. You might be able to tell me how to add the MX on the top of Struts, or similar MVC Java web application: replaying JSP, the V with MX, also the V with least possible work. I don't know any Struts books out there. But you shall be able to find tons of on-line tutorial in the subject. Remember Google is yor friend. One book I can recommend is Advanced JaveServer Pages by David Geary. The frameworks introduced in the book are very similar with those in Struts, including MVC one. If you want to write back, please send to my email address.

That exhaustive background was meant to help you fine folks make book recommendations for me. I have bookmarked and visit some of the excellent online resources for Struts and Java, but I'm the kind of guy who likes to spend money, have something bound, with a glossy cover, sitting on my desk - it's like a security blanket to me.

Re: RE: How can I get a value from a Javascript for a formbean?
Hi, Mark,
Thanks for sharing your code.
I haven't use Javascript a lot and am sort of figuring out how the JavaScript code
works: the data will be stored in the
formbean after the submit button is clicked. It will great appreciated if you can
elabourate how it works with a formbean.

Re: RE: RE: The right place/time to clean up a session before sessiontim e out, or user logoff
Jason, Your solution covers the log off case. How about session time out, say, a user leave a page of the application and browse another site. There isn't log off action in this case. 9/23/2002 7:31:36 PM, Miller, Jason [EMAIL PROTECTED] wrote: -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
User Notification
I need to implement a message system, sort like email but inside the Java web application only for its users. After one user, A, sends a message to another, B, B shall be notified to retrieve the updated messages if B is on line. I plan to implement messages as stored in a DOM. My question is how the notification shall be implemented. I only use a web container, and considering to add in a JMS server for IM. Any suggestions?

The right place/time to clean up a session before session time out,or user logoff
In order to keep track of who is online, I need to keep a list of on line users. When a user sign in, which can have more than one routes, an account information object is created. The class implements the HttpSessionBindingListener interface. The user id is added into the list in the valueBound method. I would like to have a single one place to remove the user id from the list when user sign out, or session time out. The valueUnbound method is not a good place since the session is invalidated already when the invalidate method is called. The sessionDestroyed method of the HttpSessionListener interface isn't a right place neither.

Re: RE: The right place/time to clean up a session before session time out, or user logoff
I have tried something similar with yours: a object stored in the session and with a HttpSessionBindingListener implementation. When the invalidate method is called in the logoff action, it is too late for the valueUnbound method to retrieve anything from the session since it is invalid already. 9/23/2002 2:56:58 PM, Miller, Jason [EMAIL PROTECTED] wrote: -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: User Notification
I don't follow you. Can you explain with more details? 9/23/2002 3:55:04 PM, Eddie Bush [EMAIL PROTECTED] wrote: Yeah you could persist it to a DB though and show the message from the DB when they ask to do that... and just rely on your session-manager-thingie for notification. James Higginbotham wrote: Ok, then you could use JMS to store a message in a topic and check for it on each request to show the user an indicator if a message exists. But, unless you turn off persistence for the topic, you will be using a DB on the backend anyway. And a query against a DB on a field that is indexed (such as the userid) would be very fast. The other option (assuming you are using only 1 server or have sticky sessions in place) is to create a session manager that you store these messages in a list, stored in a hash keyed by user id. It would probably be a singleton within the app server's VM. You would then check this manager on each request and show the indicator/message as appropriate. Just attach a session listener so that when the user's session times out or you kill it forcefully, your session manager will drop any existing messages. Course, this isn't persistent so if the user isn't signed in, they will never get the message (thus, see option 1 and previous posts to this list).

Re: RE: User Notification
What else would you suggest? The reason I am thinking about use DOM is that messages are stored in a XML format in DB since the number of messages can vary. The XML format data needs to be parsed either SAX or DOM. If DOM parsing is too slow, SAX parsing into a collection object is a way to get around. 9/23/2002 3:03:49 PM, Galbreath, Mark [EMAIL PROTECTED] wrote: I hope he means stored as an XML doc.

Re: RE: RE: The right place/time to clean up a session before sessiontim e out, or user logoff
Jason, Now, I see what you're doing here. Rather than calling the session invalidate method in the log off, you call the method to clean up the session. That is some thought. I, however, think there shall be a more straight forward solution than twise thing around by the servlet desing. Thanks for explaining your solution.
