Java pragram running in Background ?????

hi ,
Can i write a java program which runs in the Background ... What i mean to say is
Eg: Process.java
I compile it and execute it say java Process .
But now what happens is the program runs but it occupies one of the Unix shell .And once i close this shell the Process is stopped .
Is there any way by which the process.class runs in background ?? and i use that unix shell to compile another program with the above Program running in background ..
I hope iam clear with the Question
Please help me out ..
thanks in Advance,

use javaw command in running java program in background. This command is specially for windows platform.

Java code running as background process in Linux causes high CPU util.

I'm running a piece of java code as a background process in Redhat 7.1 . When I specify to run it as a background process (using the '&') at the command line, I get CPU utilization at around 5% and it dips.
When I edit the script that runs the java code to specify running it as a background process withint the script itself (java ..... &) and then go to the command line and run the script, the CPU utilization shoots up to 95% and stays at the low 90's - very high 80's range for the CPU utilization..
I'm hoping someone has any idea for this behavior and a way to fix it.
Thanks in advance,
Sarat..

This is an interesting post and i'm sory i don't have time to
experament before i answer
you could of course run the script as background
*.sh &
but that's probubly not what you want
I think the solution lies in giving the
proccess a job number %n
then setting it %n &
it might even work to
put something like %java &
Anyway when it's running fullout
it is because it is in the
current terminal process group PID.
wish i could help more

Can Web dynpro Java application run as background application

Hi Experts,
Is it possible to execute the Web dynpro java application in background without opening the application in a web browser.
We just want the WD java application deployed on the SAP Web AS server to be invoked and get executed as a background application by some external web application. It should not get open at any point of time in a web browser.
Can anyone suggest if it is possible?
Thanks & Regards,
Anurag

Hi Anurag,
Since Web Dynpro is "SAPu2019s standard UI technology based on MVC for developing user interfaces" (see http://www.sdn.sap.com/irj/sdn/nw-wdjava) it is by design not possible to run 'in the background'.
There are other possibilities to develop server processes per your requirements, such as developing web services or servlet development.
Web services are the de facto standard for executing business logic on a remote server. However, as I understand your external web application is not capable of sending web service requests, have you tried the servlet approach?
See http://help.sap.com/saphelp_nwce711core/helpdata/en/3f/f8bc3d8af79633e10000000a11405a/frameset.htm for more info on how to develop a servlet using NWDS.
Take particular attention to the sub-topic 'Servicing Client Requests' of the above guide
Hope this helps!
Best regards,

Running In Background on Server

I am with a Sender and Receiver application where the Receiver runs on a Server and the Sender runs on the Client. What I would like to do is have the Receiver run on the server and continue to set and run waiting for files to be transmitted. I attempted to put a for loop in the program however, the program generated this following thrown exception when I sent a file the second time:
Exception in thread "main".util. NoSuchElementException
at java.util.StringTokenizer.netToken(Unknown Source>
at UDPReceivedr.<init>(UDPReceiver.java.52)
at FileReceiver.man(FileReceiver.java.63)
The following code is provided for review:
import java.net.*;
import java.io.*;
import java.util.*;
// UDPReceiver class.
public class UDPReceiver
    DatagramSocket s;
    String filename, initString;
    byte[] buffer;
    DatagramPacket initPacket, receivedPacket;
    FileOutputStream fileWriter;
    int bytesReceived, bytesToReceive;
// UDPReceiver method.
    public UDPReceiver(int port) throws IOException
       // Define instances.
      s = new DatagramSocket(port);
      buffer = new byte[8192];
      System.out.println(" ** Server is ready to receive file on port: "+port);
      // Here we want to wait for the client to send a file.
     initPacket = receivePacket();
     initString = "Recieved-"+new String(initPacket.getData(), 0,
             initPacket.getLength());
     StringTokenizer t = new StringTokenizer(initString, "::");
     filename = t.nextToken();
     bytesToReceive = new Integer(t.nextToken()).intValue();
     // Announce that the file to be received will be saved
     // as a pre-determined filename and the number of bytes
     // expected to receive.
    System.out.println(" -- The file will be saved as: "+filename);
    System.out.println(" -- Expecting to receive: "+bytesToReceive+"

                     (new String("OK")).getBytes());
   // Receive the transmitted file from client.
   fileWriter = new FileOutputStream(filename);
   // Write the file out.
   while(bytesReceived < bytesToReceive)
          receivedPacket = receivePacket();
          fileWriter.write(receivedPacket.getData(), 0,
                     receivedPacket.getLength());
          bytesReceived = bytesReceived + receivedPacket.getLength();
        fileWriter.flush();
        System.out.println(" ** The file transfer from sender is now

    } // end UDPReceiver method
    // receivePacket method

}The main is located in another program, which calls this class. I have been looking at running this applicatiion as a Windows Service but I am not sure if that would allow the program to continue running in the background.
Any help with this would be appreciated.

The crazy thing here is it will run properly if I allow it to run once, transfer the file and receive it, and let the program complete and teminate.
If I attempt to set this class in a loop I get the thrown exception. I would really like to have this run in background and continue to run and not terminate after each Send and Receive. Is there a way to do this?
The diagram for this would be:
1. Run and wait for sender to send file.
2. Receive the file and write it out to the local dirve.
3. Notify the client the send was successful.
4. Go back to sleep and wait for another file to be sent.

How to make a program run in background?

Is there any ways to make an invisible program with java? a program that is running in background but the user cannot see it and it's not in the Start bar and the user cannot close it.

There are also 3rd party software that lets you install a java program as a service in winnt/2k/xp so that you can start/stop it from the service manager, doesnt even matter if the java program is gui based or not, as there are options (in win2k at least) in the service manager that allows the program to interact (think show gui) or not...one software called JNT comes to mind..
Anyway, if you're using win98/me equivalent, then just use javaw.exe like suggested by previous posters.

Report program when run in background job getting cancelled immediately

Hi
When i run a program in foreground i am able to see the output. But when run in background not able to run the job successfully. The job is getting cancelled immediately.
I am using the below function module for output display. Should i need to pass any parameters in the below function module so that i can run the program in background successfully.
CALL METHOD DETAIL_GRID->SET_TABLE_FOR_FIRST_DISPLAY
      EXPORTING
        IS_LAYOUT         = IS_LAYOUT
        I_SAVE            = 'A'
        IS_VARIANT        = GS_VARIANT
      CHANGING
        IT_FIELDCATALOG   = IT_FIELDCATALOG
        IT_OUTTAB         = BLOCKED_STOCK_TAB_ALV[].
Please suggest.
Thanks and regards
Rajani Yeluri

Hi Rajani.
ALV require the DRYPOR(screen) for display but incase you run in back ground which have to write to spool but in spool we can only write in format of LIST REPORT not inter-active report like ALV. That why
system cancelled your process immediately.
Hope it helps.

When MRP run through background process in MDBT open PR and PO not comming?

Hi,
When MRP run through backgroung process in MDBT open PR and PO not coming in MDBT result.
Pls advise accordingaly.
Regards
rk

Ram,
Either I am totally misunderstanding your statements, or your business people are misinformed.
The output of MD01 (MRP total run in foreground) and the output of MDBT (MRP total Run in Background) ARE IDENTICAL, provided you have selected the same parameters.
Neither output contains a discrete listing of open Purchase orders and Purchase requisitions.
Standard output of both MD01 and MDBT are:
1. List of materials processed, with exception messages
2. Statistics
In addition, both of these programs also write MRP records to the MRP databases, provided that the "Display Material List" parameter is set. In this case, both of these programs will produce data that can be further reviewed and managed in MD05 and MD06. MD06 is the tool that most planners use to process the MRP database info.
If you wish to see a listing of the entire MRP results (either MD01 or MDBT), then execute transaction MDLD. This will produce either a spoolfile or a printed document.
For the PO or PR listings, review my earlier suggestions.
Rgds,
DB49

GUI_GET_DESKTOP_INFO is not worked when run in background

Dear all,
I want to retrieve the computer name using this function module. It is working fine in foreground but it returns no result when I run in background. Is there any other method to get the computer name in background? Thanks in advance.

Problem solved using the following method:
DATA: BEGIN OF usr_tabl OCCURS 10.
          INCLUDE STRUCTURE uinfo.
DATA: END OF usr_tabl.
DATA th_opcode(1)                    TYPE x.
data: size type i.
CONSTANTS: opcode_list LIKE th_opcode VALUE 2.
CALL 'ThUsrInfo' ID 'OPCODE' FIELD opcode_list
    ID 'TAB' FIELD usr_tabl-sys.
describe table usr_tabl lines size.
read table usr_tabl index size.
write usr_tabl-term.
while usr_tabl-term is the computer name. It works in background as well.

Error when OO ALV report run in background

Hello all,
We recently applied stack 12 for a 7.0 system. My custom ALV report using CL_GUI_CUSTOM_CONTAINER coding now returns an error when run in Background. It works fine in dialog.
The error occurred in program CL_GUI_CUSTOM_CONTAINER=======CP. The log message was "Control Framework: Fatal error - GUI cannot be reached".
Is there a solution for OO ALV reports run in the background? I would not like to re-write my ALV reports using the function call. Any advice is appreciated. Thanks!!

Yes, you need to code it a little differently, but you can still use CL_GUI_ALV_GRID. Here is an example.
REPORT ZRICH_0006 .

System is showing time out when run in background

Dear all,
We have two systems: One R/3 and EBP. We have made one report where the remote function module will be called from R/3 to EBP. There are 4 lakhs data in SAP. We are sending 10000 data as package in internal table and getting the corresponding output. But the system is showing time out when the report has run in background. Can you please suggest how the process can be improved so that the timeout can be avoided.
Thanks and regards,
Atanu

Hi,
Try to fetch records in smaller chunks and process them. For example, if you are trying to fetch records for one year, instead of single query, try to fetch in 12 sets for each month. Fetch first month and process the records and put them in the output internal table. Then go for next month and so on. Anyway your program is running in background. There will not be any user complaint also. The solution might sound bit funny. But it works.
