Open alert-ish window from jsp?

Hi, I'm trying to find a way to alert the user of my jsp that he entered non-valid chars in my inputfields. Usually I'd do this in the js-validation of the input on submit but I was wondering if I could get the jsp to do something like it on submit? I mean, in stead of out.println, then out.println in a new window? I know it's rather circumstantial but I got curious :)
My reason for not doing it in js is that I have a try catch validating if my entered string is an int. I know it's doable in js too but hey.. can't blame a girl for trying something new, right? :)

JSP is all server side so you would have to post your form to your servlet and have it validate and then redisplay the form to the user if they entered something bad.
Best bet is to do your validation with js and use alert boxes.

Is there a way to open a new window from the "Go" menu in Mavericks?

Before Mavericks, I was able to go from the Finder to the top menu "Go" -> "Utilities", or Applications or Home… and a new window would open.
Now I have to manually open a new window to avoid loosing my existing window.

Is there a way to open a new window from the "Go" menu?
First, as others have already stated.....make sure the checkbox is deselected for "open folders in tabs instead of windows" in Finder Preferences.
If you're like me and don't like tabs very much, there is a way to make folders always open in windows with a simple click (I'm using Mavericks 10.9.5). Go to a root folder (for example, the Documents Folder), open it, and select View > Hide Toolbar, then all folders within that root folder will open in a new window.
As an alternative method, any folder can be opened in a new window by holding down either Command Key while clicking the folder. But sooner or later you will forget to hold down that key, and then clicking on a folder will open in a tab (which will automatically resize the window and cause much aggravation).
The Hide Toolbar trick will also work with any folder present on the Desktop. It will make all folders inside that folder open in new windows.
To make the Applications Folder open in a new window when opening it from the menu bar at the top of the screen, you will have to open the main hard drive folder and use the Hide Toolbar trick. This will cause all folders inside it to open in new windows.
Hope this helps.

I attempt to open a second window from the icon but it does not open then when firefox is closed it will not reopen because it is still running in processes but no window displayed until you kill the process and then restart firefox.

I attempted to open a new window from the Firefox icon but nothing happens. I then went on browsing and closed Firefox but was later unable to open it. I checked processes and it was already running but there was no window displayed. I am running Windows 7 Professional.
This is repeated any time I already have the browser open and wish to open a second instance.

Safari won't open to 'all windows from last session'

Safari is set to open to 'all windows from last session' - but it opens to a blank page. Not every time, but 75%+. I usually have multiple tabs open, not always the same ones, and this is slow, annoying and tedious to frequently reconstruct where I left it.
Any ideas?
I just moved to a MacBook from Windows and I am surprised to have an issue like this crop up so quickly (or well ever - based on Apple's reputation, that is - and all the glowing things my firends and associates have told me)

Open a Finder window. From the menu bar click Go > Go to Folder
Type or copy / paste the following:
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
BTW, if you enable the Develop menu you can empty the Safari cache easily instead of having to go through your user library.
From the Safari menu bar click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Then from the Safari menu bar top of your screen, click Develop > Empty Caches

"open in new window"- from favorites panel - bridge

Hi Bridge, I love your way of working
However 2 things make my hair rise
- I can't "open in new window" from a favorited location. only in the "content" panel... which is rather "weird"
- I have to "reveal in finder" to be able to zip/rar files.
Please fix this, I know i am not the only one who would love this.

- I can't "open in new window" from a favorited location. only in the "content" panel... which is rather "weird"
To be honest, I never thought about that option, I always use the shortcut cmd + N for a new window and point to a folder in either folder panel or favorites panel. There is always something to learn
Having the same option in Favorites as in Folder panel would be very logical indeed!
- I have to "reveal in finder" to be able to zip/rar files.
I think you are bound to do so always because Bridge is in fact a browser and in itself not capable of editing files. The export panel did some tasks with resizing but has been discontinued in CC.
Only if Adobe made an application to unzip or open other packages the possibility for using the tools menu and reach the start up script for such app would be the shortest road possible to my knowledge. But also AFAIK Adobe does not offer such application.
And using MacOsX 10.8.4 my downloaded zip files are unzipping themselves automatically...
Please fix this, I know i am not the only one who would love this.
This won't work because this is a user to user forum, use the feature request option here:

Opening a Modal window from another Modal window

Hi All,
I am opening a Modal window from a Modal window which has applets in it. But when the child modal window opens up from parent modal window, the applets on the child modal window are not loading properly. But when I change the child modal window to normal window, then applets loads fine.
I just want to know how different is a modal window when compared to normal window when it comes to applets.
This is the problem which showed up only on specific machine but not on all the machines.
Is this because of some specific settings or could be any other reason?
Any help Pls!!!
Regards,
Rajesh.

Christian,
This problem is occuring on 2 machines which has Java 1.5. But rest of the machines which has 1.5,1.6,1.4 are supporting modal windows. So not really sure whether its a browser issue or JRE issue or it is how the modal windows behave in an inconsistent way. Really need a solution for this problem as early as problem.
Regards,
Rajesh.

Can/Could/Why-Can't-We Open a Terminal Window from Finder...

I do a lot of development needing a terminal window but also need to bounce about a lot between file system areas (my machine, our NFS drives in our fleet, etc.).
It'd be nice if we could open a terminal window from Finder. I.e., If I'm in Finder and see that I need to work in the terminal window (be it with IDL*, NCL, gcc, etc) I can do a quick GUI click or keykick or whatever, and be happily dropped into a terminal window in that directory. The alternative for me now is to open Terminal from my doc and dig through the file system to my destination.
Can I do that in Finder? I seem to remember in a past life with (ahem) an certain other "operating system" that just released their "apology" edition, that you could do this from their File Exploder. If not, gee, wouldn't that be nice to add, kids?
Bill

Thanks for the help on this!
The Matt's macoshints solution (the first comment by Greg Spence, below) was simple enough and met my requirements very nicely, thanks much. (the script is below)
tell application "Finder"
set myWin to window 1
set theWin to (quoted form of POSIX path of (target of myWin as alias))
tell application "Terminal"
activate
tell window 1
do script "cd " & theWin & ";ls -al | more"
end tell
end tell
end tell
It worked on the local mac, my unix nsf drives, and the samba drives to which I am connected.
I also tried the cd-to script but as I use tcsh it was not working for me. Other potential users have apparently cited the problem as well (nice simple icon graphic for the finderbar though).

Thank you again :)

I have some windows minimized. When I try to open up another window from the start menu, even the minimized windows open up.

When I first open up a window from the start menu, just one window opens up. But when others are at the bottom (minimized) and I go to open up a new window from the start menu, all the minimized windows open up, too.

That can a problem with the Ask.com toolbar (Tools > Add-ons > Extensions)

You would need to use javascript, in firefox this would opena new tab, in IE it would open a new window. Google for window.open and you should find some examples of how to do this.

Opening a browser window from a CHM (Win7)

Hi All,
I'm having a problem where a script we've had for years to open a special window (sized, no browser buttons, etc) for certain content is no longer working correctly in Windows 7.
Here is the script:
function OpenWindowSize(strUrl, u_width, u_height) {
var w_width = ",width=" + u_width;
var w_height = ",height=" + u_height;
var strOptions = "scrollbars=yes,resizable=yes"
strOptions += w_width;
strOptions += w_height;
strOptions += ";";
var newWin = window.open(strUrl, "newWin", strOptions);
// newWin.document.close();
newWin.focus();
WinXP & Vista: a link within a CHM correctly opens a new window with only scroll bars, and resizable, with the specified dimensions (e.g. u_width=500, u_height=700)
Win7: a link opens in a regular browser window with full menus, etc and not sized to the specified dimensions. An error also displays in the CHM file.
CHM error message (snippet): 'newWin' is null or not an object.
A developer managed to get the CHM error to go away by adding if (newWin != null) above the focus() line.
He also managed to prove that the problem only exists within CHMs. When the same javascript is used in plain HTML, the window is called correctly, as per the WinXP & Vista example above.
Does anyone know how to get my script working in Win7 so that it is sized correctly and doesn't have the menus/buttons?
Thanks,
Amber

Hey All,
I just got a message from PatricioV2, for this...I totally forgot to come back to the forum...I was so busy trying to work out the solution that now, I forget the specifics, but I did find out that there is NO WAY to customize a pop-up window from a CHM with IE 9 or 10 installed...any pop-up will have ALL the browser timings. And since I didn't want that effect, I abandoned that idea and pursued a different solution.
However, I was able to use jQuery Colorbox...which really surprised me. But even with this, you cannot use "linked" images from the stylesheet so the controls don't show...so, you need to "style" the elements with color values (i.e. background, borders, etc.).
Also, and very important, if your content is in an IFRAME in the CHM (which mine was), you MUST use a jQuery technique to get your colorbox to work on the PARENT window...otherwise, the colorbox effect will happen ALL INSIDE THE IFRAME...
...and on a side note: the code in the original post is very close to the code I was using...but all I needed to do was define the value of NULL and the script worked without any errors (which is in a post above)...but not being able to style the pop-up just ruined it for me...

I can't open any new windows from File [New Tab] and from clicking on [+] , as I usually did. And [Ctrl+T] doesn't work for me.How I can make it to work for me again, please?

I have to open the next window by right clicking on some link from previous site, who gives, '''''from drop down menu''''', option to [Open link in new tab] and then I can use that "fresh" tab.
It is my desktop, if it's important to know for help.
Please, some ideas, how to fix it, will be welcome.
Thank you.
