Is it possible to create muliple sessions for the same user. If a user opens two browser windows, both windows share the same session scoped beans.

Re: java
When upgrading to a higher JDK version, like from jdk1.1.7 to JDK 1.2, Sun might have changed some of the API included in the JDKs. The changes are usually renaming method, changing parameters of existing methods or even canceling the method completely. Each change method which does not exist anymore in its older version is said to be deprecated. The documentation of each JDK states which methods were deprecated. When you compile with the -deprecation option, you can get an exact message about the deprecated method you used. You should then refer to the new documentation and see how you should use this method from now on.

Package loading
I'm not very awared of using external classes in JSP. It might be a trivial question, but how could I load packaged classes in my pages ? The only way I found until now is to had my package classes directly in the server's jar archive (/lib/jrun.jar in my case). And then I'm able to import whatever I need, which is exactly what I want. But I'm sure there might be another way. Maybe do I have to change some parameters of my server (JRun as I said before), but I'd prefer a solution directly included in the JSP source, if possible. BTW, I'd like to know more about beans loading in JSP, because I'm not very familiar with them. Is there a place where I could find some exemples ? Thanks Sylvain
Re: Package loading
In the server, JRun from my experience, there is a parameter setting for the classpath. This is in the JRunAdmin under the General tab and under the Java tab there. Just add the jat with the full path into the classpath and it will be able to load any class from there. You can change the classpath directly in the JRun properties file without the JRUn admin. It is easier. Just go to JRUN_HOME\jsm-default\properties and edit the jsm.properties file. change the variable java.classpath Good Luck -Original Message-From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of Sylvain RocheSent: Thursday, June 10, 1999 3:16 PMTo: [EMAIL PROTECTED]Subject: Package loading I'm not very awared of using external classes in JSP.

Re: FW: How do you send them back to where they came from?
In HTTP terms, you are asking for the "referer" page -- the one that contained
a link that pointed at the current servlet. To retrieve that, just say:
String referer = req.getHeader("Referer");
and it will be there. This will return NULL, however, if someone had
bookmarked the servlet URL and then just executed it from their bookmark (or
just typed the servlet URL into their browser), so your code needs to watch
out for a NULL return valuve here. Perhaps you could go to a default JSP page
in that case.

Any other thoughts? You're not telling us the whole story yet, so that's why you don't get the right answer. How do you call the servlet from the JSP? Which JSP implementation do you use? That's the important information. If you're using a JSP 1.0 implementation and jsp:include, the request attribute "javax.servlet.include.request_uri" contains what your looking for (see JSP 1.0 Appendix B). But I believe the current reference implementation doesn't yet support dynamic content (such as a servlet) through jsp:include. Instead it implements the "public draft 1" specification, where jsp:request include=file performs the same function. The "javax.servlet.include.request_uri" is also set if you use a scriptlet to get a RequestDispatcher for the servlet and then using the RD.include method to call it.

Hi, I'm curious to know if PageContext objects are pooled? If so, this pool resides in JspFactory?

Title: RE: How do you send them back to where they came from?
You can do this in JavaScript. Add the following code to your JSP file after all your server-side processing is done:
script language=javascript
if (document.referrer)
{
location.replace(document.referrer);
}
/script

POST and browser behavior
I'm working on a JSP shopping cart implementation, and am having a problem getting a desired behavior. Here's what happens with my shopping cart: -- my cart -- (1) User is viewing the cart, (2) User changes the quantity of item(s) in the cart via a form (METHOD=post), and submits. (3) Quantity is updated. (4) User changes the quantity of item(s) again. (5) User hits back button. (6) With IE5, user gets message "Warning: Page has expired," and is invited to hit the refresh button. (7) User hits the refresh button, and their quantities are back at what the were at step (3). This is clearly not optimal! For an example of what I'm trying to accomplish, check out amazon.com: -- desired behavior (e.g., as at amazon.com) -- (1-5) as above (6) No problem -- user is simply taken back to the previous screen (7) User clicks on "view cart" (or whatever) and the correct quantities are displayed.

Re: POST and browser behavior
As far as I can tell, this is a "design decision" on Microsoft's part. My guess is that they felt that POSTing a form is usually done for some sort of submission of data, for security reasons, you shouldn't be able cache the results of a POST. (For example, you're on a public terminal, and you POST an order at Amazon, and it then displays your address. You leave the terminal, and the next person to use the terminal could use the browser's 'Back' function to see the results of your POST, which maybe contains your address, account number or whatever.) But this is just a guess on my part. The only way I've found to get around this is not to use POST. Not really much of a solution. I've tried messing with the HTML headers, but it appears that IE ignores whatever you send. I've found that I don't need to use POST that often. Submitting search parameters, for example, work fine as GET. And since you can't cache the result of a POST, you can't really put anything worthwhile on the page that results from a POST. I usually just put a "Success!" type of page, maybe with an ID. In the orignal message, Glen was looking to have behavior similar to Amazon. I was thinking that Amazon used GET when you add something to your cart, but it seems they dont. But the page that results from the POST doesn't expire in IE. Wierd. Anyways, my advice still stands - use GET if you can. -Original Message- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of Lastname Firstname Sent: Thursday, June 10, 1999 11:17 AM To: [EMAIL PROTECTED] Subject: Re: POST and browser behavior I would also be interested in an answer for this.

Problems Getting Started with JSP 1.0 RI (was: Re: JavaServer Pages 1.0 Public Release)
JSPers, We are very, very sorry for the difficulty in ease-of-use in this release of JSP. The team is closely monitoring the list and will be fixing the problems as quickly as possible. Please stay tuned and we'll have something to you shortly after JavaOne. Thanks for the support this group has given to those just getting started on JSP. With improvements to usability, we hope the list can stay as one forum that is useful for all participants.

If you are on this mailing list, I'm sure you have a pretty good idea where the install instructions have gone wrong and where things can be improved. This really is in Sun's best interest to improve the JSP site, as I'm sure that you would love to see JSP dwarf ASP (and hence sell more servers). But to do this, you need developer's to learn it and endorse it. For each x amount of developer's that download the JSP implementation, a certain % of those won't get it working because the install instructions aren't complete and will give up. Others will find that there really aren't any great tutorials and books on the subjectWhat a wasted opportunity...It's less likely that those developer's will come back. My point is not to try to criticize but to encourageThink of things from a marketing point of view. (The ASP tutorial is very straight forward and any Joe Blow can get it running quicklyWith JSP, you better come to the interest list or you're SOL...) Also, this mailing list is transforming into a forum of "how do I get started." Awhile back, Lastname Firstname (just joshin') suggested two distribution lists, one for more advanced discussions. Maybe you want to consider this as more users begin to hear about the 1.0 release and flood the mailing list. I've noticed the more advanced users on this list have been silent as "newby" mail has been overwhelming. Since I am in the "newby" stage as well, I don't mind the email, but the more technical discussions seem to be absent.

Re: POST and browser behavior
So if the same problem shows up on multiple browsers, multiple servers, and GET/POST is irrelevant, let's revist the possibility of HTTP headers. A page can be set to expire by one of 2 methods. Set an HTTP header or use a META tag in the HTML. The same methods can also be used to say that a page expires immediately or that it never expires.

Re: POST and browser behavior
Some ideas that might be useful. 1. Use POST but then do a redirect. You post to a page that updates the state (say add something to the basket) and then redirect to a page which display the new state (contents of the basket). This way the user can hit reload and it doesn't reapply the post. This still doesn't solve the back problem, but is useful in some situations. 2. Use GET with a unique request id. Each GET link contains a unique id that the server uses to identify repeats requests. For instance, your "add to basket" link is a get link which contains this id. The server adds the item to the basket and stores the request id. If the user calls the "add to basket" script again with the same request id, you simply don't add the item and present the contents of the basket or whatever you normally do after an item is added. The next time you present a page with an "add to basket" link you use a different request id. These are simple approaches, but are useful in some situations. -topher Unfortunately, GET is not appropriate all the time.

Re: Applets with Servlet or jsp
The only possible way that I see is the same way one would call a servlet/jsp from within an applett using the http (hyper text transfer protocol). There are tons of programs which to similiar things (such as Tik , a TCL script which querries different news sites to gather news headers). This way I dont think that servlet/jsp are the only ones you could use. Any CGI would serve this purpose. Now if security of others accessing your servlet/jsp is important I would also setup that your applet sends in the get http header some unique name that would identify it from all the rest (netscape / ie/ mosaic/ lynx/ kfm/mozzila/opera... and others) I remember seeing one applet use a Netscape Server on NT connecting to CGI that was an .exe file. It was some applet based store system, that used cgi to connect to DB (back when RMI didnt exist).

Re: POST and browser behavior
The original "problem" was that the user set a quantity and did a POST. The user-visible result of the POST was evidently to redisplay the same page. Then the user changed a quantity and instead of hitting the submit button again, hit the back button. After going through the awkward but irrelevant IE refresh dialog, the previous page was displayed with the previously entered quantity. Why is this a surprise? That's what the back button does. It's a user error. Bob Foster Symantec Internet Tools http://www.visualcafe.com/ __ Reply Separator _ Subject: Re: POST and browser behavior Author: Taggart Gorman [EMAIL PROTECTED] at Internet Date:6/10/99 11:57 AM As far as I can tell, this is a "design decision" on Microsoft's part. My guess is that they felt that POSTing a form is usually done for some sort of submission of data, for security reasons, you shouldn't be able cache the results of a POST. (For example, you're on a public terminal, and you POST an order at Amazon, and it then displays your address. You leave the terminal, and the next person to use the terminal could use the browser's 'Back' function to see the results of your POST, which maybe contains your address, account number or whatever.) But this is just a guess on my part. The only way I've found to get around this is not to use POST. Not really much of a solution. I've tried messing with the HTML headers, but it appears that IE ignores whatever you send. I've found that I don't need to use POST that often. Submitting search parameters, for example, work fine as GET. And since you can't cache the result of a POST, you can't really put anything worthwhile on the page that results from a POST. I usually just put a "Success!" type of page, maybe with an ID. In the orignal message, Glen was looking to have behavior similar to Amazon. I was thinking that Amazon used GET when you add something to your cart, but it seems they dont. But the page that results from the POST doesn't expire in IE. Wierd.

QUESTION:Does the JSP:REQUEST directive work for JSP files or onl y servlets
I am using the sun reference implementation of JSP 1.0
I have the following JSP Files: "JSPExample.jsp" and "ToDoListTable.jsp".
The problem is that the jsp:request include="ToDoListTable.jsp"/
does not invoke a "nested" JSP file and as such be processed as a JSP
servlet. It seems to be only looking for plain servlets (i.e. no JSP
processing).
The example shows a "To Do List" implementation with a nested
JSP file called via jsp:request include="ToDoListTable.jsp"/
to render the HTML table showing the list items.
Note: To do items are added via the form included in "JSPExample.jsp".

Re: Applets with Servlet or jsp
Elliot Rusty Harold has a fabulous book on Java network programming. I shows examples of how to do this. You can do something like applet.getAppletContext.showDocument(url) to replace the current page with something else. If you want the current page to remain, but go get info from the server and display it within your applet, you have 2 options. 1. Use sockets (java.net.socket). 2. Use java.net.HttpURLConnection.

This way I dont think that servlet/jsp are the only ones you could use. Any CGI would serve this purpose. Now if security of others accessing your servlet/jsp is important I would also setup that your applet sends in the get http header some unique name that would identify it from all the rest (netscape / ie/ mosaic/ lynx/ kfm/mozzila/opera... and others) I remember seeing one applet use a Netscape Server on NT connecting to CGI that was an .exe file.

Re: POST and browser behavior
GET does not have a body ( all the data has to be send in the URL) POST has a body which contains the data in URL-encoded format. GET appends the form variables string to URL using (?) POST send the form string data as request body (check HTTP protocol spec) its easy to test web application if you only use GET.

Re: POST and browser behavior
Search the MSDN Library for any of the following strings: Expires ExpiresAbsolute HTTP-EQUIV META Here's an example of how to set it in HTML. Put the META tag inside the HEAD tag. META HTTP-EQUIV="Expires" CONTENT="Tue, 04 Dec 1996 21:29:02 GMT" Here's an example of how to set it in HTTP, along with 2 other headers. This is from an embedded web server I built. The zero tells the browser to expire the page immediately. Otherwise, replace 0 with another number to indicate an amount of time, in minutes, after which the page should expire. HTTP/1.1 200 OK Content-Type: text/html Expires: 0 In ASP, you can say Response.Expires = 10 to expire in 10 minutes. JSP probably has a similar syntax.

A page can be set to expire by one of 2 methods. Set an HTTP header or use a META tag in the HTML. The same methods can also be used to say that a page expires immediately or that it never expires.

Unfortunately, GET is not appropriate all the time. In the case of a shopping cart application, using get would cause the form to be re-executed automatically, which defeats the purpose (see my original post). Somehow, amazon is managing to do this successfully. Internet Explorer (IE) 4.01 experiences the same problem Incidentally, Netscape 4.5 does, too. c I'm working on a JSP shopping cart implementation, and am having a problem getting a desired behavior. Here's what happens with my shopping cart: -- my cart -- (1) User is viewing the cart, (2) User changes the quantity of item(s) in the cart via a form (METHOD=post), and submits. (3) Quantity is updated. (4) User changes the quantity of item(s) again. (5) User hits back button. (6) With IE5, user gets message "Warning: Page has expired," and is invited to hit the refresh button. (7) User hits the refresh button, and their quantities are back at what the were at step (3). This is clearly not optimal! For an example of what I'm trying to accomplish, check out amazon.com: -- desired behavior (e.g., as at amazon.com) -- (1-5) as above (6) No problem -- user is simply taken back to the previous screen (7) User clicks on "view cart" (or whatever) and the correct quantities are displayed. I've looked for a setting on HttpServletResponse, but to no avail. amazon doesn't seem to be using any META tags or special FORM tags that I can see. Help!

Re: POST and browser behavior
Bob Foster wrote: The original "problem" was that the user set a quantity and did a POST. The user-visible result of the POST was evidently to redisplay the same page. Then the user changed a quantity and instead of hitting the submit button again, hit the back button. Not exactly -- the user hits the submit button *again*, and then hits the back button. Thus they are rightly expecting their quantities to be what they changed them to the second time. After going through the awkward but irrelevant IE refresh dialog, the previous page was displayed with the previously entered quantity. Why is this a surprise? That's what the back button does. It's a user error. As for it being a user error, I can't argue with you. However, it's an error that many users might make; I'd like to save them the trouble. The fact remains that on amazon's site, user's don't get what you accurately describe as the "awkward but irrelevant IE refresh dialog." I'm just curious how they (amazon, that is) manage it. c === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JSP-INTEREST".
