Now If I press F5 (I am not clicking the ADD button) it again adds a new record(duplicate record) in the database, which it should not do. I have added the following line in my Action Class response.setHeader(pragma,no-cache); I have also added the following statement in the struts-config.xml controller nocache=true/ But still it is adding the duplicate record in the database when i press F5.

RE: [OT] Transaction Safe Java Code
If you r using the same connection for both the methods, then u can
rollback. I wud suggest you to do sth like this
Main method()
{
Open ur connection
Method1(pass connection object);
Method2(pass connection object);
Rollback or commit the connection based on ur exceptions etc.
Close the connection
}
I guess the above shud be doable.

RE: javax.servlet.ServletException
Your action entries in struts-config do not have any form beans
associated with them. If that is the case, no form beans will be created
for those actions. This means that 'form' parameter in execute() method
is null. I am not very sure if this is the problem though!
Hope this works.

RE: Continuous datastream from server to client
Hi,
I have a html page which contains large data. I do not want the user to
wait till the page gets all the data. I want to start displaying atleast
some portion of data(like 10 rows) and then display the rest when the
server gets it. I guess you were discussing sth on the same lines. I was
struggling for a way to get this done in Struts.
If you have encountered this, can you please tell me how to go about it
or Can you direct me to any resources relating to this problem?

Hi, thanks for answer.
I'm using OJB for database access but for the moment without proxy. I
think the user is responsible to print only lists of acceptable lenght.
But if he wants to print a long list he should do, across ?? pages and
not page by page.
When I saw, that I could run into memory problems, my next idea was to
use
the PrintWriter from HttpServletResponse, create html code and flush
every
10th row.
But I never tried it. An other Idea is to create a PDF File in the
background. During creation I render a pagecounter on a seperate page
and
when finished I create a link on output page, but thats my last option.
So you think, there is no way to send data with undefined length from
server to the client?
I guess I had missed your original requirement that this come out as
a single document... I believe that you can send data without an
explicit content-length, but I'm not entirely sure. HTTP doesn't
have an explicit end-of-stream string or content-marker so I'm not
sure how it would know you're done if you don't set the
content-length, but I'm pretty sure i've heard of it being done...
It's certainly OK to print directly to the Response's writer from
Struts -- just return null from execute()/perform().
If you can generate a PDF file, you might consider restructuring the
application so that the user requests a report be emailed to him/her.
You can launch the generation of the report as a separate thread and
return a response promptly. This is nice if it takes a little while
to generate the report.

RE: html:submit and Image instead of button
Have a property for that bean say
Private Sting act;
and in the jsp have a corresponding hidden tag like
html:hidden property=act/
In the javascript function set the act to whatever you want depending on
the index like
function submitAct(index){
if (index==0) { document.form.act.value=act1;
}
document.forms[0].submit();
}
Finally, in the Action class get the value of the property act for the
form. Hope this helps!

Subject: html:submit and Image instead of button
Hi,
I have 4 buttons on an jsp page, but what if i have to use image instead
of buttons,
like Add
will have a button with Add Text, and then in my Action class i can find
out which button has been pressed,
but what if i have to use Image instead of a button, like how can i find
out which image was clicked if i have 4 images on a jsp with
value=sumbit
[input] src=images/en/buttons/login_off.gif width=75 height=24
onMouseOut=MM_swapImgRestore()
onMouseOver=MM_swapImage('login','','images/buttons/login_on.gif',1)
[input] src=images/en/buttons/signoff_off.gif width=75 height=24
onMouseOut=MM_swapImgRestore()
onMouseOver=MM_swapImage('signoff','','images/buttons/signoff_on.gif',1
)
the above are 2 tags with same one action=/pages/selectenv
so how will i come to know which image was clicked, what is the best way
to do it
Ashish

How to pass paramaeters to display dynamic text using html:errors tag?
Hi, I am a newbie to struts. Right now, I am able to display server side errors using the html:errors tag. But, I want to extend the functionality of this to display some dynamic text. I want to pass a parameter to the tag in Application.properties file which adds the parameter to the text dynamically and adds the object to ActionErrors class. I know this feature is supported in struts but I am not able to find any source about this. Can someone help me with this? Thanks Regards, Ravi Kora 337-739-3434(M) -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Iterating multiple collections using logic:iterate- Is it possible with Struts?
Did anyone come across the problem of iterating over multiple collection
objects in logic:iterate? The tag works fine if we have a single
collection. But I am not getting it to work with multiple collections. I
want to know if anyone has done the above using the logic:iterate tags?

Subject: RE: Html:checkbox issue
This is just a shot in the dark, but could you specify the onclick
attribute of the checkbox to run some javascript? When clicked, you
could swap the checkbox properties back and forth between checked and
not checked. Does anyone else think something like this would work
well? It's just an idea...

How do we calculate session size?
Hi all, I want to know what are the objects that come into consideration while calculating the session size. Is it only the session objects(or session attributes) which have to be considered for calculating session size? If there are some other things plz lemme know. I know I am being very dumb here but ..! Thanks Regards, Ravi Kora [EMAIL PROTECTED] 337-739-3434(M) -Original Message- From: Jon.Ridgway [mailto:[EMAIL PROTECTED]] Sent: Friday, July 12, 2002 5:47 AM To: 'Struts Users Mailing List' Subject: RE: Problem with session ojects: memory size, updates Hi, Your English is a hell of a lot better than my French...Your question is one that comes up a lot on the list try a search at: http://www.mail-archive.com/struts-user@jakarta.apache.org for 'session size'. One pertinent post is: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg34592.html In short, the answer to what should go in the session depends on how your application will be used. If you expect a *very* high number of concurrent users your session should be under 4k (taken from iAS, WebLogic and WebSphere docs, white papers etc). It will also depend on your hardware, how much RAM is available, network bandwidth, database size/speed etc. If you can predict the highest level of concurrent users, multiple your maximum session size by this. The result will be the amount of RAM taken up by all the sessions put together, if you have sufficient RAM to handle this and all over requirements, then the session size is not an issue. Note however that the number of users can explode unexpectedly, so the best practice recommendation is to keep session size as small as possible. As for the speed of looking up objects from the session, this will depend on your app server, when clustering some app servers will store the session in a db or other persistent store, lookups in this case are relatively expensive. If you are not clustering, I wouldn't worry about the speed of the lookup (even if you are I wouldn't worry about it that much - its not a bottle neck I've ever come across.) Jon Ridgway -Original Message- From: Heligon Sandra [mailto:[EMAIL PROTECTED]] Sent: 11 July 2002 15:12 To: '[EMAIL PROTECTED]' Subject: Problem with session ojects: memory size, updates Sorry, my english level isn't very good. I read that the Struts framework doesn't make (oblige) to use one particular model implementation (EJB, JavaDataObject, JavaBean, ...). But the JavaBean solution is understood or greatly recommended, isn't it ? Because struts uses JSP to display data and JSP pages use JavaBean tags. If we work whit XML representations of remote business objects, is it better to use struts XSL tags rather than generate JavaBean from the XML description ? The XSL solution requires to know XSL tags and is slower and more complex. With JavaBean solution I am frightened having memory or request time problem. The user does a request, the selected Action gets business data from the enterprise tier, generates one or several JavaBean instances and stores the JavaBean in the HttpSession. But the HttpSession size will grow quickly. It is difficult to know when we have to store data in request scope or session scope. Has somebody advices about this dilemma? I am tending to put data systematically in HttpSession in order to reduce network traffic if the user ask again this page. What is the max size of the session objects ? If we user rights on the business objects, we will have the same JavaBean in several HttpSessions. What do you think about this problem ? A last question if we have numerous session objects, when we will have to update one of them it will be very slow to find it in the list. Do you have advices about that ? Is the JavaBean/HttpSession solution realistic with real-time data?
