Multiple mark()/reset() calls
i am currently converting a c program into java, and the original program uses several getpos and setpos commands to jump around in a file stream. is there any way to use mark and reset in a similar way?
kdgregory is correct, you can't do this with the built in java io stream classes.
However you could build your own MultimarkableInputStream and support it, but it would probably be more work than you'd want.

Multiple transactions in Call Transactions
Hi All,
Can i use the below code to do multiple transactions in call transaction using the Below code.
Call Transction for XK01 using BDCDATA1
Call Transction for MM01 using BDCDATA2
Call Transction for VA01 using BDCDATA3
Please advise.
Regards
KrishnaHi
Try the following code....
LOOP AT ITAB1.
< your statements here to append the rows to internal table BDCDATA1>.
Call Transction 'XK01' using BDCDATA1.
ENDLOOP.

Capturing log files from multiple .ps1 scripts called from within a .bat file
I am trying to invoke multiple instances of a powershell script and capture individual log files from each of them. I can start the multiple instances by calling 'start powershell' several times, but am unable to capture logging. If I use 'call powershell'
I can capture the log files, but the batch file won't continue until that current 'call powershell' has completed.
ie. within Test.bat
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > a.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > b.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > c.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > d.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > e.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > f.log 2>&1
the log files get created but are empty. If I invoke 'call' instead of start I get the log data, but I need them to run in parallel, not sequentially.
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > a.log 2>&1
timeout /t 60
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > b.log 2>&1
timeout /t 60
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > c.log 2>&1
timeout /t 60
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > d.log 2>&1
timeout /t 60call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > e.log 2>&1
Any suggestions of how to get this to work?Batch files are sequential by design (batch up a bunch of statements and execute them). Call doesn't run in a different process, so when you use it the batch file waits for it to exit. From CALL:
Calls one batch program from another without stopping the parent batch program
I was hoping for the documentation to say the batch file waits for CALL to return, but this is as close as it gets.
Start(.exe), "Starts a separate window to run a specified program or command". The reason it runs in parallel is once it starts the target application start.exe ends and the batch file continues. It has no idea about the powershell.exe process
that you kicked off. Because of this reason, you can't pipe the output.
Update: I was wrong, you can totally redirect the output of what you run with start.exe.
How about instead of running a batch file you run a PowerShell script? You can run script blocks or call individual scripts in parallel with the
Start-Job cmdlet.
You can monitor the jobs and when they complete, pipe them to
Receive-Job to see their output.
For example:
$sb = {
Write-Output "Hello"
Sleep -seconds 10
Write-Output "Goodbye"
Start-Job -Scriptblock $sb
Start-Job -Scriptblock $sb
Here's a script that runs the scriptblock $sb. The script block outputs the text "Hello", waits for 10 seconds, and then outputs the text "Goodbye"
Then it starts two jobs (in this case I'm running the same script block)
When you run this you receive this for output:
PS> $sb = {
>> Write-Output "Hello"
>> Sleep -Seconds 10
>> Write-Output "Goodbye"
>> }
>>
PS> Start-Job -Scriptblock $sb
Id Name State HasMoreData Location Command
1 Job1 Running True localhost ...
PS> Start-Job -Scriptblock $sb
Id Name State HasMoreData Location Command
3 Job3 Running True localhost ...
PS>
When you run Start-Job it will execute your script or scriptblock in a new process and continue to the next line in the script.
You can see the jobs with
Get-Job:
PS> Get-Job
Id Name State HasMoreData Location Command
1 Job1 Running True localhost ...
3 Job3 Running True localhost ...
OK, that's great. But we need to know when the job's done. The Job's Status property will tell us this (we're looking for a status of "Completed"), we can build a loop and check:
$Completed = $false
while (!$Completed) {
# get all the jobs that haven't yet completed
$jobs = Get-Job | where {$_.State.ToString() -ne "Completed"} # if Get-Job doesn't return any jobs (i.e. they are all completed)
if ($jobs -eq $null) {
$Completed=$true
} # otherwise update the screen
else {
Write-Output "Waiting for $($jobs.Count) jobs"
sleep -s 1
This will output something like this:
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
When it's done, we can see the jobs have completed:
PS> Get-Job
Id Name State HasMoreData Location Command
1 Job1 Completed True localhost ...
3 Job3 Completed True localhost ...
PS>
Now at this point we could pipe the jobs to Receive-Job:
PS> Get-Job | Receive-Job
Hello
Goodbye
Hello
Goodbye
PS>
But as you can see it's not obvious which script is which. In your real scripts you could include some identifiers to distinguish them.
Another way would be to grab the output of each job one at a time:
foreach ($job in $jobs) {
$job | Receive-Job
If you store the output in a variable or save to a log file with Out-File. The trick is matching up the jobs to the output. Something like this may work:
$a_sb = {
Write-Output "Hello A"
Sleep -Seconds 10
Write-Output "Goodbye A"
$b_sb = {
Write-Output "Hello B"
Sleep -Seconds 5
Write-Output "Goodbye B"
$job = Start-Job -Scriptblock $a_sb
$a_log = $job.Name
$job = Start-Job -Scriptblock $b_sb
$b_log = $job.Name
$Completed = $false
while (!$Completed) {
$jobs = Get-Job | where {$_.State.ToString() -ne "Completed"}
if ($jobs -eq $null) {
$Completed=$true
else {
Write-Output "Waiting for $($jobs.Count) jobs"
sleep -s 1
Get-Job | where {$_.Name -eq $a_log} | Receive-Job | Out-File .\a.log
Get-Job | where {$_.Name -eq $b_log} | Receive-Job | Out-File .\b.log
If you check out the folder you'll see the log files, and they contain the script contents:
PS> dir *.log
Directory: C:\Users\jwarren
Mode LastWriteTime Length Name
-a--- 1/15/2014 7:53 PM 42 a.log
-a--- 1/15/2014 7:53 PM 42 b.log
PS> Get-Content .\a.log
Hello A
Goodbye A
PS> Get-Content .\b.log
Hello B
Goodbye B
PS>
The trouble though is you won't get a log file until the job has completed. If you use your log files to monitor progress this may not be suitable.

Hi everyone,
What I'm trying to do here is get an audio file from the jar file as an input stream and convert this to an audioInputStream. Obtaining it from the jar file works fine. The problem is that I get an io exception at the following line:
audioInputStream = AudioSystem.getAudioInputStream(is);This code all worked fine before when I created an audioInputStream using a File object. Is there any work around that would solve this?
public void beginAudio()
jarFile = new JarFile("z.jar");
soundFile = jarFile.getJarEntry("Multimedia/DMathews.wav");
if(soundFile!=null)System.err.println("sound file is not NULL here");
loadAudio(soundFile);
public void loadAudio(JarEntry entry)
try
is = jarFile.getInputStream(entry);
if(is!=null)System.err.println("is is NOT NULL");
if (is.markSupported()==false)System.err.println("mark is NOT supported by IS");
audioInputStream = AudioSystem.getAudioInputStream(is);
if (audioInputStream.markSupported()==false)
System.err.println("mark is NOT supported by audioInputStream");
catch(Exception ex)
ex.printStackTrace();
audioFormat =audioInputStream.getFormat();
}This is the exception:

Multiple times constructors calling in Myfaces
Hi
i m fasing multiple times constructor calling for myfaces programs
i have created a small web appl. with one text box and one submit button, to test this behaviour.
i have used this sample to
get web page
enter some text value
submit the page
and atlast page get returned to me
i don't understand the multiple times consturctor calling and exact sequence of Getter/Setter calling?
Following are details -

that blog was really good and in depth...
but i have one real time problem with multiple time constructor calling
if you replace text box with file upload tag in my earlier sample program and then following is out put ...

----------- trailing exception stack trace...
Calling Constructor...
getUploadedFile()...
form this output u can find that my UploadedFile backing bean object gets null just before form submit method...
whereas its has been properly instantiated in setter method,
if constructor (1 wasn't call then object (uploadedFile) can be found in method (FileUpload.uploadFile)
i have also tried to make scope of backing bean Session , but constructor, getter & setter calling sequence doesn't different even after.
i have also considered both of your blog as ---

Open Transaction MM01/MM02 with multiple views using CALL TRANSACTION
Hi All,
I want to open MM01/MM02 with multiple views using call transaction but in the parameter ID for Views (MMX) I can pass status of only one View.
SET PARAMETER ID 'MAT' FIELD v_mat.
SET PARAMETER ID 'VKO' FIELD ' '.
SET PARAMETER ID 'MTA' FIELD IT_MOFF-MTART.
SET PARAMETER ID 'MTP' FIELD IT_MOFF-MBRSH.
SET PARAMETER ID 'VTW' FIELD ' '.
SET PARAMETER ID 'BWT' FIELD ' '.
SET PARAMETER ID 'LGT' FIELD ' '.
SET PARAMETER ID 'MXX' FIELD 'K'. "Sales View
SET PARAMETER ID 'MM5' FIELD ' '.
CALL TRANSACTION 'MM02' AND SKIP FIRST SCREEN
Please suggest.
Regards,
DivyaI do not exactly understand what you mean, but what i already did:
- I checked that the fields are from the same type.
- KUNNR is initialized! I already had a look to the debugger, that's why i'm posting this in this forum.
any more comments on this ?
maybe i have to change anything in the z-transaction. Btw, this is what the parameter looks like in the transaction:
SELECTION-SCREEN BEGIN OF BLOCK Debitoren WITH FRAME TITLE text-001.
PARAMETERS pkunnr type kna1-kunnr OBLIGATORY.
SELECTION-SCREEN END OF BLOCK Debitoren.

How to mark a call as unhandled, manually sending a call Result
Hello,
I will appreciate if someone could help me with this issue. In ucce campaign file, several phone numbers are defined for an account number(BAAccountNumber). Now, if the first phone number is reached (CallResult = 10), following phones for that account numbers are not dialed. This is a very important for us as a company, we have to find a way to mark the call as unhandled and to "tell" the Dialer to dial following phones for that account number.
Thank you, i will be very grateful if someone could give me a hintWell, the customer may not be at home at that moment, or simply the number is wrong. It's very strange that cisco offers many many options and features, but it was hard to find the right answer about this issue. Anyway, we found a way to enable Callback and Skip-Next buttons in the CAD for Predictive dialing, but sadly, still there is no jtapi implementation for these two options, so agent will have to use both CAD and our custom desktop call center software.

What means this: mark/reset not supported?
And why doesn't it happen always?
Thank you,
NicoInput streams represent a input source. The type of the source can vary, for example it could be a socket or it could be a file.
In a random acces file you can 'mark' a position in the file. One can then return to that position by 'reset'.
One of the source types you are using does not support that. -
Handle multiple application by call tran. method ?
it is possible to handle multiple application by call transaction method ?
Hi,
Yes. A simple scenario is upload of Material and its relevant stock information. SO upload of material is one process and upload of stock for those material is another process. You can use the sessions method or Batch Input method to upoload data in multiple transactions as explained above.

Hi,
I have a doubt regarding the concept of reset() and mark() methods of BufferedInputStream class. Here is the code
class FileDemo
public static void main(String[] args)throws IOException
String st = "123456789";
int c;
byte[] buf = st.getBytes();
ByteArrayInputStream in = new ByteArrayInputStream(buf);
BufferedInputStream f = new BufferedInputStream(in);
for(int i=0;i<8;++i)
c = f.read();
System.out.print((char)c);
System.out.println();
f.mark(5);
f.reset();
c = f.read();
System.out.print((char)c);
Output
12345678
9In above code when i execute f.mark(5), the file pointer should make a mark at 5th byte i.e character 5, and when i execute reset the file pointer must point back to this 5th byte and must print 5 when i print for the next time. But instead the output i get is 9 after reset is executed. Please clarify.....In above code when i execute f.mark(5), the file
pointer should make a mark at 5th byte i.e character 5No, it shouldn't.
and when i execute reset the file pointer must
point back to this 5th byte and must print 5 when i
print for the next time. But instead the output i get
is 9 after reset is executed. Please clarify.....The API documentation is pretty clear, I think, especially if you follow the links to the description of what mark() is supposed to do:
"Marks the current position in this input stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.
The readlimit argument tells this input stream to allow that many bytes to be read before the mark position gets invalidated." -
This folder was not one I created, but it appeared to be a part of the bookmark area. It save all recently saved book marks and was called "Recently Bookmarked". I used this feature last night and this morning when I went to use fire fox, it is gone.
I tried restarting Firefox and it still has not fixed the problem. My question is, How do I get this feature back or how do I create a folder where everything I book mark goes into the folder until I can sort the book marks into the proper folders? thank you for your helpSee:
*https://support.mozilla.org/kb/Restore+the+default+Smart+Bookmarks+Folders
* "Recently Bookmarked" is a so called [[Smart Bookmarks folders|Smart Bookmark]] that shows the result of a place query in a list.
* "Most Visited" and "Recently Bookmarked" and "Recent Tags" are examples of so called [[Smart Bookmarks folders|Smart Bookmarks folders]] and are not real existing folders.
* Smart folders show a list created by a query of the places.sqlite database that stores bookmarks and history in Firefox.
* Smart folder lists show a maximum of 10 entries by default.
* Bookmarks and history items that show up in a smart folder list are stored elsewhere in another folder and any changes made are applied to the real bookmark or history item. -
Hi,
We need to configure multiple IP addresses in a Call Manager version 8. Our customer has three diferent IP networks: One for management, one for signaling and one for media. Call Manager is connected to those networks using three NICs with different IP Addresses a should separate traffic.
Is it possible in CCM? I guess no, but is there any work around to get this functionality?
Thanks and best regards.
RaulNot possible in CallManager, but you can achieve this with "VRF select" on IOS routers

FILE to multiple BAPI/RFC calls
Hi,
I have one input source (CSV with about 100 rows) and I wish to call a custom rfc for each row in my spreadsheet. (The custom RFC has a single flat import structure as opposed to a table or anything complex).
I am struggling to do this in XI.
I assumed I needed to assign one source to multiple targets in the Message interfaces, but this errors on activation due to the RFC occurrence being set to 1.
Do I need to do the same trick as with IDOCS or am I missing the point somewhere?
I have read several threads and one in particular seems to indicate it is possible, but so far this has evaded me.
Re: BOM CREATION
Please could you point me in the right direction.
Thanks
AndrewAndrew,
You could read the CSV file into an Integration Process
Save the message in a multiline container (in your case 100 rows)
Create a block
Create another container to hold the single row defined within this block
Set the following for the block
<b>Step Name</b> eg SplitForRFC
<b>Mode</b> ParForEach
<b>Multiline Element</b> Multiline container defined above
<b>Current Line</b> Single line container defined above
The <b>Mode</b> 'ParForEach' acts like a loop
Then within the block create a synchronous Send step which calls your RFC
<b>Design</b>
I would question having to make 100 RFC calls
If possible change the design so that the RFC interface can accept multiple messages and the RFC logic to loop through them and process the messages one at a time

EventListeners for multiple remote object calls
Hi all,
I have a Flex component that is displaying content from multiple (specifically two) remote object calls. I can call both remote methods, get the results back, pass them off to their respective ItemRenderers, etc. with no trouble. What I need, though, is a way to determine if I get no results back from either function call, to dispatch an event to trigger the next view state, and I don't know how to do that. Something like:
protected function ticketConfigurationStateChangeHandler(event:Event):void
if(getPackagePromptsResult.lastResult.length == 0 && getTicketPromptsResult.lastResult.length == 0)
this.dispatchEvent(new Event("ticketConfigurationStateChange"));
protected function ticketPrompts_creationCompleteHandler(event:FlexEvent):void
getTicketPromptsResult.token = registrationAPI.getTicketPrompts();
getTicketPromptsResult.addEventListener(ResultEvent.RESULT, showTicketConfiguration);
protected function packagePrompts_creationCompleteHandler(event:FlexEvent):void
getPackagePromptsResult.token = registrationAPI.getPackageCPrompts();
getPackagePromptsResult.addEventListener(ResultEvent.RESULT, showPackageConfiguration);
Any suggestions would be greatly appreciated...I know I need the event listeners to be able to get lastResult.length (and have it not be null) but I don't know how to set them up so I can automatically pass the user through the component and onto the next one if there are no results returned without having the user click a button or something similar on an otherwise blank component.
Thanks in advance!
