Can JSP handle multiple windows?

Hi,
What I am going to do is:
I have multiple windows, each has several forms to let the user to set database query conditions. The query result will depends on all the conditions specified in all the forms of all the windows.
Question:
Can I use one(or more) .JSP file(s) to handle this situation? if not, could you give me some hints?
Thanks a lot in advance!
-Wendy

I don't know how you will manage to forcefully grab informatoin from a different browser window. The user will have to hit return on each before it can be seen.
Well unless you put the data into the session as it is being entered. This will likely require some javascript or VB Script. Whatever it is, its going to be nasty. I would onlyy do this as a Masters Thesis experiment :D

  • How can I have multiple WINDOWS (NOT tabs) with INDEPENDENT content?

    How can I have multiple '''windows''' (''not ''tabs) with '''independent''' content?
    I used to be able to open separate windows with Firefox, and the content could be completely different in each window. No matter what I did in any window, no OTHER window open at the time, nor any of the content therein, was affected. This is no longer the case and it is extremely frustrating for me.
    I do ''not ''like tabs and do not use them. I prefer multiple windows plus I am so used to using them, for so many years now! But with v9.0.1 I suddenly can no longer do what I've always done with my browser without this aggravating problem constantly reminding me that I can't have what I want in firefox anymore.
    Or can I? Does anyone have a solution I don't realize exists?
    Thanks,
    Sowelu

    AppleScriptObjC can use pretty much everything in the Cocoa API, so yes, it is possible.
    Note that a view is not the same as a window, and a window can have multiple views. There are also many ways to implement "tabs";  take a look at some of Apple's applications - they use various mixtures of toolbars, checkboxes, and radio buttons, for example.  An application such as this will be a lot more involved than what you have done so far though, using custom classes and subclassing existing ones, so be prepared to do a lot of reading and researching.

  • IE running under XP can't handle multiple SWF files, Why?

    I noticed that IE 8 running under Windows XP cannot handle multiple swf files in one page.
    Up to about 10 files is no problem they are loaded and we can play them ( buttons that start a small audio file).
    But more of these files in one page will stop IE.
    Firefox ( 3.6.28) runs them fine.
    And also IE 8 and/or Firefox under Windows 7 handles them perfectly.
    Has anyone any idea what can cause this and how to resolve this?
    Thanks,

    Sorry...I still don't get it. What is it about Windows FUS that keeps iTunes from running running the process twice? It can run many other non-Apple windows apps in multiple user sessions (commercial apps, open source apps, audio/video apps, networked apps). I can even run two different virtual machines at the same time under two different user sessions.
    Why can iTunesHelper.exe run twice but iTunes.exe cannot? Why can I run Safari at the same time? Quicktime Player runs fine under multiple user sessions.
    Blaming it on Windows and/or FUS sounds like FUD. Can anyone give a valid technical reason? Semaphores? Mutexes? An admission (and explanation) that the Windows version is purposely crippled?

  • Best practice for JSP app- multiple windows

    Hi all,
    I am looking for some opinions on whether I should construct my app so it uses multiple windows. eg. If someone opens a master record and clicks a link, I can display details in a seperate window. Obviously this has the advantage of being more user-friendly ala a thick client as the user can view multiple windows at once, etc. I've seen many web apps that do this but many that have opted not to also.
    I am interested in the common 'pitfalls' associated with multiple-window web apps and why I should/should not use them. Obviously, opinions vary but I'd like to get some feedback on this. Also, any link(s) discussing this would be greatly appreciated.
    Thanks,
    Mike

    Err...
    JSP is generally used to embed sippets of Java code within otherwise existing HTML pages. It is possible to dynamically generate the resulting Javascript code that will create additional windows, or the Applet code that will likewise spawn new windows in response to user activities.
    For the most part, I do something along the lines of the former suggestion, that is, I write code like:
    out.write( "<A HREF=\"show_detail.jsp?id=" + id + "\" TARGET=\"detail_window\">" + id + "</A>\n" );...and the result is that if the user clicks on a link, a new web page is loaded into some other window.
    Is this a valid way to go? Certainly. Are there any drawbacks? Yes. Many users actually don't want multiple windows, that is, they click on the link, it opens a window - fine. They click on a similar link, it should load the relevant data into that companion window, not load yet another window. The primary reason being that closing all those windows is a bit of a pain in the behind.
    Beyond that, I can't really offer any suggestions that are not application specific. If I think of any, I'll come back to the thread.

  • Can i open multiple windows or tabs in itunes?

    Hi,
    When I look for downloads with Safari I can open multiple tabs to compare items and efficiently use my slow connection. Now apps for iPad are in iTunes, where that option doesn't seem to be possible. Very annoying.
    Or am I just missing some trick for opening additional tabs or windows?
    thanks

  • Can we handle multiple fields delimiter in sql*loader

    Hi,
    Users wants to load the data from each of their individual system. But problem is when they save the csv file, due to their sytem setup some files gettng saved with pipe (|) seperated and on some system it is saved with comma (,) sepearted fields.
    Can we handle both these field seperator in control file?
    Please suggest
    Thanks,
    Rahul

    Rahul,
    I recommned you should use "|" as "," can be embedded in a text string. I guess you can pass a directive to use to deliver "|" delimited file :). If you want to handle both then you might have to write a shell script or bat to pass delimiter as an argument which will edit and replace your control file.

  • How can I implement multiple windows/tabs in my Main-Menu?

    I don't really know how to explain it. As an example, Skype has roughly 20 windows bundled with it, that are switched to when you click things like "Skype-Home" and "Profile". The layout changes too drastically to change the way it looks through just code, and it's not a new window being opened, it stays in the same window, the same main-window. I was wondering if this is possible through Cocoa-Applescript, and if so, what are the necessary steps to achieve this.
    Taking it one step further, and if the above is possible, how could I implement a "tab" system in the application? The image below is an example of what I mean.

    AppleScriptObjC can use pretty much everything in the Cocoa API, so yes, it is possible.
    Note that a view is not the same as a window, and a window can have multiple views. There are also many ways to implement "tabs";  take a look at some of Apple's applications - they use various mixtures of toolbars, checkboxes, and radio buttons, for example.  An application such as this will be a lot more involved than what you have done so far though, using custom classes and subclassing existing ones, so be prepared to do a lot of reading and researching.

  • Can you open multiple windows of the same Keynote presentation?

    Like you can in PPT, where you can go Window > New Window, and see more than one slide at once of the same presentation in the large view. If there is any way to view more than one slide at time, in the large view, please let me know.
    I know about Light Table, and that's useful but I really want to be able to open multiple instances of the same presentation like I could in ppt.

    Thanks, I will. It seems like such an obvious thing, yet I could not find anyone referencing it anywhere. I thought I was the only one who used ppt (or now keynote) that way. Otherwise it is awesome, so much better than PPT.

  • Can we handle multiple forms  in struts application

    In one jsp i will handle a form based on the input ,I must retrieve data and set it in another form class is it possible if so how
    addResource.jsp
    <html:form >
    <html:text name="resourceForm" property="resourceId" />
    </html:form>
    In action class method
    retrive resourceid based on that retrieve employee information
    and need to set in another form for display is it possible

    you can forward the request to a different action before redirecting to the second form, create another action like
      <action path="/secondFormAction"
                      type=""
              name="secondForm">
              </action>
    then in your resource form action
    <action path="" name="resourceForm" >
        <forward name="success" path="/secondFormAction.action"/>
    </action>the secondFormAction will create the form for you and u could put the data in request attribute and access it in the secondFormAction and then pupulate the data in the secondForm and then redirect the request to the second JSP.
    hope you have got the point here, I wouldnt wont to paste anycode until you try it out.

  • How can i show multiple windows on start?

    Hi everybody:
    I have an application that need to show 5 windows at the same
    time when the application is started. The 5 windows are seen but
    the canvas is not shown, so, i see 5 windows with no elements. I
    have tried with SHOW_WINDOW built in, but it only shows the
    window, not the canvas. If i use the GO_ITEM built in, in one
    item from each block i can only see the last block visited.
    Is there any property that i must change in canvases? (the
    raise on entry is in "yes"); i have to do anything else?
    Thanks.

    Windows have a property called "Primary Canvas". This sets what
    canvas should be shown in a window by default.
    Typically Forms knows what to display because the cursor is in
    an item, the item is on a canvas, the canvas is required to set
    its Window...you see the window with everything in it.
    The window property primary canvas for when you do a show_window
    and do not navigate to anything in the window.
    Thanks,

  • Can iTunes handle multiple versions of the same app?

    Now that iTunes, iOS, and iDevices have been around long enough for users to have multiple devices on multiple iOS versions, is Apple doing anything to allow users to run multiple versions of the same app through iTunes?
    Case in point I have an older iPhone running iOS-5 with a few apps that are now running exclusively on iOS-7, my new iPhone is on iOS-7. Once I sync my new phone with the updated versions of the app, iTunes usually dumps the old version into the trash bin. But what if I need that older version to continue running it on my iOS-5 iPhone?
    Is there a workaround for this? I've considered using an old PC as my base computer for sycning the new iPhone, but I still fear that the new app updates will go to all devices running on my iTunes account through iCloud.
    If Apple doesn't address this problem at some point then as the years go by certain iDevices will eventually become completely useless even if they are a fully functional piece of electronics.
    (spare me the "that's their plan, corporate greed" replies).
    Thanks in advance!

    Yes, the apps SHOULD be developed to work with the new stuff, No, not all apps keep their old versions in the App Store, BUT, finally Apple has ALLOWED developers to have multiple versions of an App in the store.
    The problem isn't about retarding development, it's about Apple trying to force users to buy new things that they don't need because the old thing, though it works just fine & has the apps that you need, is unable to be used because the apps have been updated in iTunes. Why can't you allow me to keep Facebook 5.0.1 for my old iPhone 3G that is used as an iPod, Facebook 6.7.2 for my iPod Touch & Facebook 19.6.4 for my new iPhone 8? As of now I can download the old version on the old device, but when I sync it it always tries to 'Update' it & then says 'Can't be updated because this version is incompatible with this device' making the sync take 3x as long & meaning that if my device crashes for some reason or I choose to restore it becasue of problems I have to go find the old version, hoping that I saved it, delete the new version, drag in the old version, THEN sync & then move the old version back before updating from my other device (Having done this with the 3G & iTouch 4 for years I learned that when the sync transfers purchases from the phone it 'replaces' the file instead of moving the old 1 to the trash).
    Some of these apps I have purchased, & by forcing the update to remove the old version Apple is essentially taking something I have purchased & saying I am no longer allowed to use it.
    Just in the what 3 months since the new iOS came out I have noticed that now over half of the apps can't be run on my iPod Touch 4G.
    It's simple, iTunes should either:
    Keep a record of the devices that have synced (I know, it already does) & keep the newest version for the lated iOS in iTunes
    Let users have multiple versions of the same app in iTunes & allow us to disable update checks for certain apps
    Allow users to choose to download from iTunes the different versions of the apps available from the developer
    OR
    Allow users to edit the info on Apps, unlinking them from their original & updates & allowing users to keep an old version & still download a new 1
