How to check whether file exist or not?

Use exists() on a File instance.

URGENT!!! how to check whether file exist or not on client side?

hello,
i am building appilication using JSP and javabeans.
Problem is my application is like on server files are there for say colors and their corresponding car image in that color.so when i move my mouse over that particular color ,its corresponding car image is displayed.
now say someone has deleted that corresponding car image file but image of color is there...........
so i have to handle such excpetion.
like if corresponding car image for that color is not there then that color image should also not be displayed.
i dont want to do this checking on server side.
pls help me!!!!!!

You don't have access to the client files. It is a security violation in a normal internet environment. Imagine what people could do to your computer if they could see everything on it.

How to Check Images File Exist? in different server

Hi,
I have 10 different coldfusion server.
for example 9 server is for the web application site - for
example
http://myserverone/studentweb
the other one is for images website, just for displaying
student picture - for example
http://myserverimage/studentpicture.
the purpose of this website is to display student picture
that i store as gif files.
from my studentweb website i will call the images from
studentpicture website as source for my image placeholder.
for example this is my code i'm calling form
http://myserverone/studentweb
website:
<img src="
http://myserverimage/studentpicture/#studentnumber#.gif"
alt="" name="studentpicture" width="160" height="200">
my problem is, if there is no specific student picture in my
studentpicture website, then the placeholder will display an X (
mean the images not found )
how do i prevent the X to display?
how do i using coldfusion or any kind of way to check if the
images exist on that website ( different server ), so if the images
is not found, i can display a default images? i can do this if i'm
calling the website in the same server, but not using a different
server.
this is like using other website images for your own personal
website and sometimes the owner delete the images from their
website, and i want to display my own images if that images been
removed from the source website.
anyone have done this before?
thanks for suggestion and guide...

1. Use CFHTTP with method="HEAD".
2. See, if the HTTP status code is 200.
The head-method is of course more efficient, as it doesn't
need to "get" the message body. However, a status code of 200 is
possible even when the requested image file is no longer on the
server.

How to check whether a default browser is opened in the operating system?

Hi,
I am newbie here. During my work, I faced an interesting problem. I need to:
- check whether a default html browser is opened;
- check whether the browser is minimized/maximized (simply, a window's state);
- get an url address typed in the browser.
If any of these conditions is not met, I have to open the browser in a maximized view with a desired url address. I primarily wanted to do all this in Java, but it came to my mind that I should employ many techniques/technologies and combine them appropriately to complete the functionality. But, which ones? That's the problem. I just recalled Windows API, but I'm not sure if it is of any help... On another forum, some users suggested that I should consider JNI... At this time, I only know how to open a default browser (e.g. with use of the 'browse(URI uri)' method of the 'java.awt.Desktop' class) - that's too little to be proud of. Please give me some hints, maybe links to reasonable discussions, I would greatly appreciate any suggestions how to approach the problem.

How to check if a user session is active in Java application server

Hi Experts,
We have a online scenario with a third party system by which a portal user will launch the third party application in a new window from portal. The SSO will work at the third party web application with the dynamic key that is generated by calling a webservice for that user. Now, as the user works on the launched screen, they will have to check whether the user (logged in portal) session is still active. ie., they will be periodically calling a service hosted by SAP java application server to find out whether the corresponding user who launched the session is still logged in or logged out.
So, my question is, how can i find out programatically whether a user/user's session is still logged in/active in SAP Netweaver Java AS? We are in version 7.3.
Kindly help me in this regard.

How to stream flv files from a diffferent directory outside the applications folder

Hi everyone,
I want to stream the flv files from a different location
stored in the hard disk, which is outside the applications folder
in the FMS installation root directory. Does anyone know how to do
it?
Regards,
Diptanu

VOD changes won't help him, he said outside the applications
folder. According to adobe any new vod folders must be in the
applications folder, hence virtually worthless for most purposes. A
better question may be, how do you specify a folder on a different
local hard drive. I wish adobe wouldn't make it so complicated, it
should be a really simple matter.

Saving a file in a particular folder over the tomcat server

I have a java class in the background of a JSP which creates an XML file and saves it.
Furthermore another class picks that file and processes it. While running this program on my local computer it is obviously working fine but in order to run it on a tomcat server or for that matter any server, I want it to save the XML file in a particular folder, for example:
tomcat_home/webapps/myapplication/ xmlfolder / something. xml
so that my other class can easily pick up the file and I dont need to change the location each time I change the server.

You can get the context root(the place from wher the aplication is running) of your application and then save the file somwhere, but i >>woulden't recomend that. But this is what you are looking for.How ?
You can also just save the file, it will be saved in a temp directory. (use this only if the file is a temp file not for storing purposes)Just saving the file somehow doesnt work for me as the folder where a class is saving a file by default is somehow different from the folder where another class is trying to pick a file by default. Even if I give no path
Other option is just to configure a tomcat system variable that specifys an folder. You can get that property from your application and >>then save the files there.Im not able to consider this one because the application will be put on different servers by different people later so they would all then need to configure their systems just to read a file. I was sure there were better ways. :(

Working with File Properties on the Application Server

Checking Whether Physical Standby is in Sync with the Primary

I writing script to alert dba if primary and standby database are not in sync. I use article - How To Check Whether Physical Standby is in Sync with the Primary? ID 861595.1
It suggests comparing Last Sequence Generated on primary and Last Sequence Received on standby for each thread. And if they are not equal - NOT in sync.
My assumption is that if there are multiple threads we running RAC. Is it correct ?
And if we running RAC as far as I am aware it's sufficient to have one thread in sync.
Please comment on this
Thanks in advance

Hi All,
I am uploading data from a flat file placed on the application server by a BDC program.
After the BDC has created the session i want to transfer the flat file from that folder to another folder on the application server by changing the name of the flatfile.
Can any one suggest the best way of doing this particular scenario?
Thanks in advance.

Regarding moving files b/w folders in the Application server

Hi,
I need to move the file from one folder(main folder) of the application server to another (eg, archive, error) with certain conditions.

Hi,
Here what I found was, if the file is empty, then the system is not moving the empty file to the destination , but if the file is not empty it is copying the contents and the corresponding folder to the destination folder. My intent is to copy the folder even if the contents of the folder is empty to the destination folder and delete the old file.
regards,
John
