File Handling (Check for existing file)

now my problems is that i need to have a code that upon a request checks for a file (in the home dir) and if the file exists reads the information and ouputs it. here is an example:
check if file TEST.DATA exists?
check approved TEST.DATA exists
information outputed...
if the file is missing i need to have an error message...
PS. sorry if the question falls under "lame" but i am fairly new to java and i dont know the commands that well... thank you in advance!

File.exists()

  • Why does multiple handles created for the file File (RW-) C:\Windows\winsxs\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4940_none_d08cc06a442b34fc

    I am analysing the file handles created by my desktop application and when i generate a report using handle.exe, in report i could see multiple file handles created for 
    1) File  (RW-)   C:\Windows\winsxs\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4940_none_d08cc06a442b34fc
    2) File  (RW-)   C:\Windows\winsxs\x86_microsoft.windows.common-controls_6595b64144ccf1df_6.0.7601.17514_none_41e6975e2bd6f2b2
    I could see around 80 entries of file1 and around 5-10
     file 2 .
    What my understanding about the WinSxS, should load the dll only once and should keep referencing the same dll. But what my results out from handle.exe contains multiple file handles created. Is there a glitch in system or is it expected behavior? If there
    is a problem how to fix it?
    My system configuration is as follows
     OS windows7 enterprise edition , service pack1..
    64 bit os,  intel core i7 processor
    .net framework 4.5
    Thanks

  • Can't get Firefox to load at all after trying fixes from support web site. Have checked for lock file, processes running, reboot, reinstall. NO JOY.

    I'm running Vista for operating system on an HP laptop that's about 2 years old. I've installed all current updates.
    I've always used Firefox. It started crashing and creating processes but not launching. Went to support and scoped it out -- there was a lock file my profile directory. I deleted it, and Firefox started loading.
    Used it a few times -- closed the app each time on exist as per suggestions on support site info. One time -- back to square one, wouldn't load, just created a process. Reboot, ending process, checking for lock file, reinstalling -- all unsucessful.

    Below is from using a SIP build.  It does offer G722, but it's way down on the list so it's never used...
    m=audio 32678 RTP/AVP 0 8 18 102 9 116 101
    a=rtpmap:0 PCMU/8000
    a=rtpmap:8 PCMA/8000
    a=rtpmap:18 G729/8000
    a=fmtp:18 annexb=no
    a=rtpmap:102 L16/16000
    a=rtpmap:9 G722/8000
    a=rtpmap:116 iLBC/8000
    a=fmtp:116 mode=20
    a=rtpmap:101 telephone-event/8000
    Taking Sreekanth's suggestion to try a Skinny build, I get the following when I make a call.  It offers codecs in the order I SET THEM AND ONLY THE CODECS I SET!  YAY!
    m=audio 19374 RTP/AVP 9 0 101
    a=rtpmap:9 G722/8000
    a=fmtp:9 bitrate=64
    a=rtpmap:0 PCMU/8000
    a=rtpmap:101 telephone-event/8000
    Using a Skinny build on the phones also solved other issues.  The phones use G711 when the whole path supports G711 and G722 when the whole path supports G722.  It doesn't always use G722 and rely on transcoding for the call paths that can't use it.  It's fantastic..  The phones also receive the QoS tagging that I set and that seems to result in better audio quality than on the SIP builds, which never did get those settings.  Finally, it even solved a slow Exchange 2013 answer issue I have been experiencing for quite some time.  I practically fell out of my chair when I saw everything that was fixed just by switching...
    Cisco, PLEASE FIX YOUR SIP BUILDS!  It's insane how the SCCP builds work perfectly and the SIP builds don't, especially with how much these phones cost..  I was thinking of possibly acquiring some 9951s, which are SIP only.  I'm a little leery about that at this point.  If they have the same kinds of issues as the SIP builds for the 7975g, there's no SCCP alternative to use..
    Sreekanth
    Thank you for suggesting a Skinny build..  That was about the only thing I didn't try.  I am happy beyond belief that this is working so well now, even though the SIP builds should be just as well developed as the SCCP ones.

  • XI30 File Adapter - check for (NOT) incoming file

    Hi!
    We use XI30 SPS15 and have the following challenge: We expect every
    week on a certain day a file coming from a customer. So far so good.
    But now we want to check whether such a file has really come within a
    given period of time and if not, we want to take some action (e.g.
    trigger Alert or s.th. like that).
    Business Background is: If the customer does not send the file or he
    sends it too late, we cannot bill him in time, thus increasing our DSO.
    Is there any mechanism within the XI to check things like these and to
    trigger an alert? I've read the File Adapter Documentation as well as
    the BPM documentation but I could not find any hint.
    Any help would be great. Thanx!
    Regards,
    Volker kolberg

    hi volker,
    this is not supported in standard but...
    you can do it very easily with standard ABAP job scheduling
    - you schedule a job (every week, day etc.)
    which starts a raport that send a RFC (or abap proxy call to the XI)
    - then the RFC starts a BPM and inside it triggers a
    java proxy that checks for a file
    - if the proxy finds the file then if copies it to some other folder (which is monitored by another flow)
    - if it doesn't find the file it triggers an error - sends mail or anything
    the only thing you need to code is a few lines in java
    to check the existance of a file + copying nothing else:)
    this is the easiest way I believe till now <= Sp15

  • Encode Video Files not working for avi files

    Hi,
    I've been trying to convert some .avi files to apple format using Lion's native 'Encode video files' function however keep getting a 'avconvert: source file not found for source file://fileparthhere avconvert: failed to create an export session. Check setup
    I can't work out why as this has worked before in Lion and works fine for other video formats. The only thing I've done is remove Final Cut Express HD and can't add it again as I don't own it anymore
    Suggestions? Is there a encoder to make this work or should it work anyway?
    Thanks

    If you click Yes the project file will be updated when you save it. That has nothing to do with the media.
    Are the Lesson and Media folders still in the Book Files folder (or whatever it's called)?
    Select one of the clips in the browser and use Edit>Item Properties. One of the first lines is Source. That gives you the file path for where your media is supposed to be located. What does it say? If nothing is there, use the File>Reconnect function and point the application to where the media is located.

  • 64 bit Photoshop CS 5.1 Extended crashes every time I create a new file or open an existing file

    I installed the 64 bit version of Photoshop CS 5.1 Extended successfully.  It opens fully without issue.  However, any time I create a new file or open an existing file, it crashes. 
    I figured this would have something to do with my graphics card, but it still does the same thing after updating the drivers & nVidia software.  Seems like my whole trial will end up expiring before I ever even get to use it!! Please help!!
    System details:
    Windows 7 Home Premium, 64 bit
    Service Pack 1
    AMD Athlon II X2 215 Processor 2.7 GHz
    4 GB RAM
    nVidia GeForce 6150SE nForce 430

  • Is xmp files only availble for RAW files?

    When we develop a RAW image with Camera Raw, we always get an xmp file with all the settings,
    But after I developed a JPG image, I saw the Camera Raw Settings icon appeared above the right upper corner of the image thumbnail in Bridge,
    however, I couldn't find the xmp file.
    Is xmp files only availble for RAW files? JPGs or TIFs don't have xmp files for their Camera Raw settings??

    Read-only didn't work for me, on a single jpg file, although it did lead to some interesting behavior.  Set the read-only attribute on a jpg file in Windows XP and then tried the following:
    1.  Opened in Bridge, then into ACR 5.4.  Performed some edits, then tried "Done", received permissions error and would not save edits.
    2.  Did the same except now invoked "Open", went into CS4 with edits intact and allowed saving out as different file.  However, the ACR edits were not saved within the jpg, as expected, nor was a xmp created.
    3.  Removed the read-only attribute, repeated (2).  Even though did not save file in CS4 the "Open" action did embed the edits into the jpg.
    So read-only doesn't really allow creation of a xmp file, other than perhaps temporarily for transfer to Photoshop.  It does lead to somewhat inconsistent behavior, in that I would have expected the "Open" to fail also since it could not bury the edits in the jpg.

    trying to copy a 10gb file to a memory stick but there's an error msg, file to large for the file format of the stick. is there a way around this

    If you use 'Disc Utility' you can format the stick (this will erase its contents) to be exFat which will still work with Mac and Windows but allow a larger file sizes to be placed onto the stick.

  • Checking for existing Rollback Segments

    Hello you all,
    Is there a possibility to check for existing rollback segments within procedures?
    Thanks

    Hello
    If you just want to be able to find out what rollback segments there are, you can query dba_rollback_segs, which will give you all sorts of info about rollback segments.
    Is that what you need or is it more involved?

    Hi all, I have a script which returns the path for a file in this way:
