How to open log file while program is running?

Hi,
I am using log4j to generate a log file. The application connects to a remote server and does some updates on a database. Is it possible to view the log file while the program is running? When I click on the log file to open it, I get a message "the document is in use by another application and cannot be accessed".
Looking for ideas to get around this problem.
Thanks and Regards,
Harsha Hegde

tail.exe -f
Tail is a Unix program but if you search google you can find a port for Windows. It will show the contents of the file in a cmd prompt and will update as new lines are being added to the file so you can see the most up-to-date version as log4j is writing to it.

How do i change default program for opening mp3 files

Hi all, i would like to change the default program for opening MP3 files, it is currently iTunes, i would like it to be MPlayerX or QuickTimePlayer, ii am sure it is easy once i know where to look, it is easy in Windose, is has just got to be easier with my Apple
Tim

Tim,
Right click on one of your MP3 files and select "get info". In the get info screen you can select the default program to open the file. Then select Change All.. to make it the default for all MP3s.

Hi when i switch on the macc 41 files open at once can not open any files while this is happing can still use AI & PS and the internet any help thanks...

Are you wanting to stop the 41 files from opening at once or is this intentional? At what point do they open when you power on the mac or when you boot Illustrator? What OS version are you using?
If you can answer the questions above can provide better advice, but you may be running into something similar:

How to open a file with approriate program

When I program a project I have a problem of opening a file. For example, If I open a word file I want to call Microsoft Word to open this file or if I open *.mp3 file I want to call Winnamp to open this file etc... I know that VC++ can do that by using ShellExecute() procedure but in Java I don't know how to do that. Can you show me how to do, please.
Thanks.

You may mostly have to do a JNI Call or Spawn a Process and do it. There is one another way of doing it. Use JNDI to search the Registry to find the Associated Program File, parse the commandline arguements and use it to spawn a Process. But I think you need some thirdparty components for Registry Access using JNDI. Try searching for JNDI Registry Access Components.

Cannot open pdf files while the Reader instance is running

Today I suddenly noticed that if I try to open pdf file while the Reader instance is already running (even if it has no pdf files open), the cursor just blinks one or two times without any further activities. So the only way to open files now is by closing the previous instance and starting the new one. I think this problem started to appear after upgrading to 11.0.3. I am using Windows 7 32 bit.

I narrowed the problem: it happens if the file is in a directory which is a join point on the NTFS file system (i.e. a link to another directory), where the link source is in turn a join point itself (i.e. we have a two-level NTFS directory link). As this is rare, it could be not a problem of the particular version of the Reader, it just probably happened by coincidence that after upgrading the first directory I accessed was of this kind.

Record Audio in mp3 file format using FMS

I am Recording Audio Using FMS which will record Audio file in FLV File Format default But I like to Record in MP3 File Format. Is it Possible.
And I also Record Video In MP4 File Format using h264 encode. Which Give me Video File in MP4 File Format but When i will try to play that MP4 File it Didn't play. So, I post-processed video with a tool called F4V Post Processor. Now That MP4 Video File Play But Didn't Give me Sound in that Video.
My Code is:
        var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
        h264Settings.setProfileLevel(H264Profile.MAIN, H264Level.LEVEL_3);
        ns.videoStreamSettings = h264Settings;
        ns.publish("mp4:"+FILENAME+".mp4","record");
I search Lot but didn't get the solution. So, Please Give me Solution for Both thing.

The .flv format is a "container" format, not a video format.
So that means that inside the container, you can have a video file and/or an audio file or even just an audio file.. which most likely is already an mp3 file. Use something like "FLV Extract" to break open the container and see:
http://moitah.net/
But really, for any Web delivery of audio, the .flv (audio only) method works just fine. Lots of media players available for the Flash .flv file.
For example:
Sounds from my bunk on the Lady Washington
http://exploreolympics.com/reports/?p=2857
Scroll down to third media player.
A little quiet to start with... but this is a .flv file with just an mp3 audio file inside.
Best of luck!

Everybody's wrong wrong wrong. You don't need garageband. Select the song, go to info. You need to select a start and stop time for the song that can't be any longer than 40 seconds in length. Then in advanced mode you convert the song to acc. once done locate the file on the computer. it should end in .m4a . Change the a to an r so it reads .m4r Drag the file to the desktop, double click and it ends up in ringtones folder.
That's it! Works every time. Or for those who want easier:

Adobe reader XI can't open mp3 files in a pdf document- says the required decoder not installed

Adobe reader XI can't open mp3 file links contained in a pdf - it says the required decoder is not installed
please help!

This is not a function of Reader, but that your computer does not seem to be configured to play mp3 files. Try fixing your file associations. The method of doing so depends upon your OS and it version number.

Type of error in the log file while using using call transaction mode u2018Eu2019

Hi Gurus,
Please Answer for this qusetion urgently
what type of error exactly you will be seeing in the log file while using call transaction mode u2018Eu2019?
Thanks/
Radha.

Hi,
Can you be clear.
In call transaction , no error logs are created, you have to handle the errors explicitly using the structure BDCMSGCOLL.
Whenever you use E mode then if the transaction encounters any of the errors i.e. data type mismatching or invalid values etc, it will stop at that screen.
You can handle the errors in call transaction in the following method.
create a table using the structure BDCMSGCOLL.
then
loop at ......
      CALL TRANSACTION 'XK01' USING I_BDCDATA MODE 'N' UPDATE 'S' MESSAGES INTO I_MESGTAB.
endloop.
SORT I_MESGTAB BY MSGID MSGV1 ASCENDING.
DELETE ADJACENT DUPLICATES FROM I_MESGTAB.
LOOP AT I_MESGTAB.
    CALL FUNCTION 'FORMAT_MESSAGE'
      EXPORTING
        ID   = I_MESGTAB-MSGID
        LANG = I_MESGTAB-MSGSPRA
        NO   = I_MESGTAB-MSGNR
        V1   = I_MESGTAB-MSGV1
        V2   = I_MESGTAB-MSGV2
        V3   = I_MESGTAB-MSGV3
        V4   = I_MESGTAB-MSGV4
      IMPORTING
        MSG = MESG1.
    IF I_MESGTAB-MSGTYP = 'S' .
      WA_SUCCMESG-MESG = MESG1.
      APPEND WA_SUCCMESG TO I_SUCCMESG.
else     IF I_MESGTAB-MSGTYP = 'E' .
      WA_ERRMESG-MESG = MESG1.
      APPEND WA_ERRMESG TO I_ERRMESG.
    ENDIF.
ENDLOOP.
Hope this is clear.
Thanks and Regards.

Cannot open mp3 file

Hi,
I got a mp3 file which i recorded recently. When i try to open it in soundtrack pro i get an error "Can't open file "xxxxx". When i open it with Quicktime Player it starts playing. I guess that during the recording there was an error at the end so the file is not correctly closed and the end of the file is corrupt.
Is there a way to fix that?
Thanks
Daniel

I also experienced this problem, not being able to open mp3 files in soundtrackpro and eventually discovered that the problem lay with the source of the file.
If I tried to open an mp3 file on an external hard drive I got the error message, when I transferred the same file to the default Soundtrack pro folder on my macpro’s internal hard drive, it opened without any problem at all.
I wonder if the problem is related to the relatively slower access speed when accessing the plug in external hard drive ?
Hope this helps.

Failed tp open .prp file while running HAL ...it says Sharing voilation ..

Failed tp open .prp file while running HAL ...it says Sharing voilation ..
I am running a HAL job.
While opening .prp file it says error Sharing voilation cannot open file.
Please help to resolve issue.

Are you sure there are not multiple instances of the prp open, say 2 remote connections both with the file open.
If there is a lock on the file and you are able to reboot the machine I would give that a go.
Cheers
