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.

i dont want to do this checking on server side.

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 the Application Server directory exits or not

Hi,
I have a selection screen in which I give the Application server file name(UNIX file) as input. Here, I would like to check whether the Server directory exists or not.
Let us say, the path I gave in the selection screen is /usr/sap/tmp/testfile.txt . Here, the file name is testfile.txt and the server directory is /usr/sap/tmp . I would like to check whether this directory /usr/sap/tmp exists in the server or not. I am not bothered about the file name as I am going to write data into the file. I am mainly concerned about whether the directory exists in the server or not. and one more thing... this is the Application Server path not the Local path.
Can anyone help me on the same how to check whether the server directory exists or not.
Thanks in advance.
Best Regards,
Pradeep.

Also you can use the FM EPS_GET_DIRECTORY_LISTING for this purpose.
Store the directory name
    l_dpath = p_file+0(l_no).
Validate the directory of the application server
    CALL FUNCTION 'EPS_GET_DIRECTORY_LISTING'
      EXPORTING
        dir_name               = l_dpath
      TABLES
        dir_list               = l_i_dlist
      EXCEPTIONS
        invalid_eps_subdir     = 1
        sapgparam_failed       = 2
        build_directory_failed = 3
        no_authorization       = 4
        read_directory_failed = 5
        too_many_read_errors   = 6
        empty_directory_list   = 7
        OTHERS                 = 8.
If any problem occurs with the directory then display proper
error message
    IF sy-subrc <> 0.
    Display error message
      MESSAGE e018 WITH 'Problem with directory entered'(008).
    ENDIF. " sy-subrc <> 0

How to check Whether the File is in Progress or used by some other resource

Hi All,
I am retrieving a file from the FTP server using Apache commons FTP.
I need to check whether the file is fully retrieved or in progress.
for now i can able to use the file which is partially retrieved. it is not throwing any file sharing exception or i am unable to find whether it is in progress.
How to check whether the file is in progress ? or The file is accessed by some other resource ?
Pls Help me.
Thanks,
J.Kathir

Hi Vamsi,
Explicitly such kind of requirement has not been catered and i dont think you would face a problem because any application that is writing to a file will open the file in the read only mode to any other simultaneous applications so i think your concerns although valid are already taken care off .
In the remote case you still face a problem then as a work around. Tell the FTP administrator to set the property to maximum connections that can be made to ftp as one. I wonder if you have heard of the concept of FTP handle , basically the above workaround is based on that concept itself. This way only one application will be able to write.
The file adapter will wait for its turn and then write the files.
Regards
joel

How do I determine if a file exists or not on my PC?

I thought this would be an easy one and maybe I am just making it harder than what it has to be. I simply want to search in a given directory to see if a file exists on not on my hard drive. Are there any ideas as to how to do this without causing an error if the file does not exist?

Hi:
In those situations what I've done till now is opening the file
and close it inmediatly, if I find out and error while opening it
I guess it doesn't exist. I know this is not the best way since there
may be other reasons for the Open File Function to fail, but it has
worked for me. Does somebody know a better way to do it?

   if (indexService == null) {
     log.errorT("Error on instanciating the index service");
     return this.renderMessage(this.getBundleString(RES_NO_INDEX_SERVICE), StatusType.ERROR);
// get index
IIndex index = null;
try {

} catch (WcmException e1) {

} else {
   log.errorT("The index " + index.getIndexName() + " is no classification index");
   return this.renderMessage(this.getBundleString(RES_NO_CLASSIFICATION_INDEX), StatusType.WARNING);
//give your KM Resource here for which you want to know if it is classified or not
boolean classified = classiIndex.isDocClassifiedInAnyTax(resource);
