Way to display the output of tail command in a Java app

Hi,
I have a Java app running in the Linux environment. The Weblogic outputs get written to a log. I would like to design a screen in my app that will enable me to monitor my logs. I normally log into the Linux machine and do a tail -f on the log.
tail -f Managed_1.logI would like to run this tail -f command from my Java app so that I am able to view the log proress from my app itself. I know we can use Runtime to run external programs but this is a case where a command will be executed continuously and the output will need to be displayed in my app, more specifically on a JSP.
Any ideas would be most appreciated.
Thanks and regards,
Ganesh

I had a look at the API for the Process class which
lists an abstract method called getOutputStream().
What I am not clear is that the documentation says
that the exec method of Runtime will return an
instance of a subclass of Process. Does this mean
that the getOutputStream() method would have already
been coded for the subclass instance returned?Yes.
And even if we do get the OutputStream from the tail
-f process, we will still have to read and display
the info on a line by line basis. Will this happend
to be fast enough to macth atleast to some extent the
speed at which the log is written to?There are two ways to answer this:
1. Ask somebody who knows how fast the log is written to.
2. Try it and see.
My approach would be the second option.

Is there a way to display the date and time on my officejet 6500

HP Officejet 6500a Plus Windows XP_ Is there a way to display the date and time on the display of my printer

Are you referring to the Date and Time some cameras put right on the image? If so there is nothing really good in iPhoto to do this. You could try the Retouch tool and see how that looks but I think you will need something more precise and powerful, like the clone tool in Aperture.
Also something like PhotoShop or GIMP - The GNU Image Manipulation Program (free) should do what you want also.
If your asking about some other date post back.

Is there a way of displaying the various item in my Downloads folder as icons arranged in order of Date Created, such that the most recent items appear at the bottom, rather than the top?

Is there a way of displaying the various item in my Downloads folder as icons arranged in order of Date Created, such that the most recent items appear at the bottom, rather than the top? I know this can be done when they are displayed as a list, but I want icons!

Hi geezer,
when you open your 'Downloads' folder choose 'View' in the Menu bar and choose:
'as List'
'Show View Options'
In 'View options' window you tick:
'Always open in list view'
'Date Modified', or
'Date created'
Now inside the 'Downloads' folder click on 'Date Created' (or 'Date Modified')
column to get items alined from oldest to newest date (or reverse)…

How to display the output screen when I use bdc.

hey expert,
I want to display the output screen when i use bdc without using mode 'A'.

You can go for mode 'E'.. it will display the output screen directly and if there is any error in the transaction you would get that particular screen and you can correct and continue after which you will get the final screen if anything goes fine...

Hi Vinod
To get the last 13 months in webi report .follow below approach
Assuming you have calendar Month object in the report.
convert your selected date into M/d/yy format . let's say you selected 12/18/13 , your variable should be 12/1/13
variable :
Selected Month =ToDate(FormatDate(useresponse("Date");"Mmm yyyy");"Mmm yyyy")
Flag for month =ToDate([CalMonth];"Mmm yyyy")<=[Selected Month]
Report filter =[Flag for month]+Previous(Self)
select the table you want to filter
add filter -> Report filter between 1 to 13.
Hope this will help.

I am trying to display the output from my ipod touch on apple tv. i can get the audio but no video. please help

i am trying to display the output from my ipod touch on apple tv. i can get the audio but no video. Thank you for any advice.

What output are you trying to get to your tv?

Way of displaying the date on the main screen in addition to the time?

I see the time displayed at the top of the main screen. Is there a way of displaying the date as well?
Thanks,

But if you leave your calendar application on the main screen, the icon itself will show the day and date.

Problem displaying the output in the same view

hi Gurus,
I have developed an web dynrpo application and have three views, in the first view I am having an input field from which I am calling a BAPI by giving that input field value as input to the BAPI.
Now is it possible to display the output also retrived from the BAPI on the same view.
Thanks and regards
kris

hi LM,
Thanks for your fast response.
I think I was not clear in explaining my problem.
I have a view in which I have an input field which is the input to the BAPI, now on entering the value in the input field I have a submit button, on clicking the BAPI should be executed and also the the output should be displayed on the same view.
Now regarding the mapping both the input and output are in the same context, would that a problem.
And also after getting the output from the BAPI I have to do some validations based on the output from the BAPI and get some message printed on the view.
Please help me in this issue.
Thanks and regards

How to reinitialize the sel screen after displaying the output..?

Hi All,
I have a report program. In the selection screen, I will provide the input parameters and execute the program which displays the output on the screen. Now, if I come BACK to the selection screen, the values which I entered earlier will appear on the selection screen. My requirement is... If I come BACK from the output screen to the selection screen, the selection screen should be blank. I mean, all the values I entered earlier should be cleared. Could anyone please tell me how to do that.
Thanks in advance.
Best regards,
Paddu.

Hi Paddu,
the selection screen will be reinitialized automatically. Only if the INITIALIZATION event or the parameters use SET/GET parameter IDs (addition MEMORY ID pid) the values will prevail.
You may clear everything in INITIALIZATION event.

Hi,
Incase you have to display this in an ALV; then your internal table will be dynamic.
Your internal table will consists of following fields
Work Centre
Date1
Date2
DateN
The date columns will not be of type d but rather character as in this columns you have to store the workcentres in them.
Create your dynamic internal table using the class CL_ALV_TABLE_CREATE and method CREATE_DYNAMIC_TABLE.
You will have to create a fieldcatalog table and pass to the method.
Then use the dynamic internal table created to store your data horizintally against each date column.
Display the output in an ALV.
Pass the date values as the description for each date column in the ALV.
I hope you get the concept.

Ankur Parab
