How can i execute ejb method in a servlet?

hi
I am using a IBM HTTP Server and Weblogic Server.
I could execute below source in a main method of application but i could not that in a init method of servlet because of ClassCastException.
(a classpath of weblogic contains client's classpath)
// source code
Hashtable props = new Hashtable();
props.pu(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
props.put(Context.PROVIDER_URL,
"t3://192.168.1.5:7001");
Context ctx = new InitialContext(props);
Object obj = ctx.lookup("session.LigerSessionHome");
LigerSessionHome home = (LigerSessionHome) PortableRemoteObject.narrow (obj, LigerSessionHome.class);
// error code
Exception : session.LigerSessionBeanHomeImpl_ServiceStub
java.lang.ClassCastException: session.LigerSessionBeanHomeImpl_ServiceStub

Have your stubs somehow got out of sync? So that your Servlet engine is pointing to a different jar than that of your jvm on which you were running your client application

How can I execute a method on a specified time?

How can I execute a method on a specified time such as method1() will be executed on 1:00 p.m and the method2() will be executed in 1:00 a.m?

As an alternative (and looks like better approach), you could use the ScheduledThreadPoolExecutor.

How can I create a method with throws instruction

Hello Everybody!
How can I create this method inside WebDynpro.
I enter "throws CloneNotSupportedException" manually an it removes always.
What is wrong ?
public java.lang.Object clone( ) throws CloneNotSupportedException{
    //@@begin clone()
     __Tdag__Is_Charactconfig that= (__Tdag__Is_Charactconfig)super.clone();
       return that;
    //@@end
Regards
sas

I only checked in my 7.1 IDE and there this section exists.
If it does not exist in your IDE, just create the method manually in the //@@begin others ... //@@end user-coding-area at the end of the controller class. This solves the issue for methods that are called from inside the controller. For public methods to be called from other controllers, this will not help.

How can I execute a Procedure with OUT variable is %ROWTYPE on SQL Prompt

Hi,
I have a procedure with OUT variable is %ROWTYPE
How can I execute the following procedure on SQL prompt.
(without creating anonymous block)
CREATE OR REPLACE PROCEDURE zz_sp_EMP(VEMPNO IN EMP.EMPNO%TYPE,
V_REC IN OUT EMP%ROWTYPE)
AS
BEGIN
SELECT * INTO V_REC FROM EMP WHERE EMPNO = VEMPNO;
END;
Thanks & Regards,
Naresh

as previous posters said: it's not possible to do this without declaring a variable in the anonymous block.
With anonymous block it would look like this (had to change it a bit, since i'm using hr-schema on oracle XE):
declare
l_rec EMPLOYEES%ROWTYPE;
begin
zz_sp_EMP(VEMPNO => 100, V_REC => l_rec);
DBMS_OUTPUT.PUT_LINE ( 'first_name = ' || l_rec.first_name );
DBMS_OUTPUT.PUT_LINE ( 'last_name = ' || l_rec.last_name );
end;
first_name = Steven
last_name = King

Hi,
You use Runtime.exec to execute commands / exe-files. See the documentation (and remember that it will only work on windows):

How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?

Hi
I have a stored procedure. It can be executed like this
exec test @p = 1;
exec test @p = 2
exec test @p = n;
n can be hundred.
I want the sp being executed in parallel, not sequence. It means the 3 examples above can be run at the same time.
If I know the number in advance, say 3, I can create 3 different Execution SQL Tasks. They can be run in parallel.
However, the n is not static. It is coming from a table.
How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?
I think about using script task. In the script, I get the value of n, and the list of p, from the table, then running a loop with. In the loop, I create a threat and in the threat, I execute the sp like : exec test @p = p. So the exec test may
be run parallel. But I am not sure if it works.
Any idea is really appreciated.

Hi nam_man,
According to your description, you want to call stored procedures in parallel, right?
In SSIS, we can create separate jobs with different stored procedures, then set the same schedule to kick the jobs off at the same time. In this way, we should be careful to monitor blocking and deadlocking depending on what the jobs are doing.
We can also put all stored procedures in SSIS Sequence container, then they will be run in parallel.
For more information about SSIS job and Sequence container, please refer to the following documents:

https://msdn.microsoft.com/en-us/library/ms139855(v=sql.110).aspx
If you have any more questions, please feel free to ask.

How can I execute program after using F4_Filename function?

Hi all,
I'm a new user on the forum. I've been working with ABAP and SAP for a few weeks. I wrote a program for importing data from excel file to SAP using BDC. During searching this forum I found information about F4_Filename function which allows users to browse the disc for a file. I'd like to add this function to my program. I have a parameter for a file name but this is an ordinary static string field. When I added the code which I found in the message on this forum the rest of program doesn't execute.
This is simple program for example:
REPORT Z_TEST8_AB.
DATA f_name TYPE STRING.
PARAMETERS p_file like rlgrap-filename DEFAULT 'c:\test.xls'.
f_name = p_file.
write:/ f_name.
This program works correctly. There is a field for parameter. I can change the default name for a file.
After all, I can run the program (F8) and rest of the code is executed. The field for parameter dissapears from the screen and the file name is displayed. ( command write)
Now I added a function F4_Filename
REPORT Z_TEST8_AB.
DATA f_name TYPE STRING.
PARAMETERS p_file like rlgrap-filename DEFAULT 'c:\test.xls'.
at selection-screen on value-request for p_file.
call function 'F4_FILENAME'
 exporting
 program_name = syst-repid
 dynpro_number = syst-dynnr
 field_name = 'p_file'
 importing
 file_name = p_file.
f_name = p_file.
write:/ f_name.
I can browse a computer for a file now but after selecting the file I can't run the rest of the code. When I click on the icon or press key F8 the field for parameter doesn't dissapier and the command write is not executed.
What do I do wrong?
Could anyone suggest me a solution? How can I executed the code after using this function?
Thanks in advance.
Regards,
Arek.

Hi arkadiusz,
1. simple
2.
start-of-selection.
f_name = p_file.
write:/ f_name.

How can I execute external application?

Hi friends I want printing my barcodes a laser printer (Kyocera) it isn't a barcode printer. So I think (and I look kyocera web page my model doesn't support barcode printing in sap) print my barcodes using an external system. Before SAP we are using JollyPrint application for printing barcodes. It is using an Excel file.
I can create a excel file for this application. I must execute this (JollyPrint-it is a label application) application when I press a button. How can I execute this application?
Thanks
Mehmet
P.S. I have been writing this message with details may be somebody can give me a simple way for this

Well, I can suggest you following steps. May be it works for you .
-Create an external OS command in SM69
-Test OS command in SM49 ( about OS command if you search in SDN youll get lot of material )
-Create a Script at your OS level, Im assuming you might have some UNIX flavor or Sun solarias.
-Create a Shell script , which execute the printer job from OS .
-Shell script will have parameters . ( e.g. printer name, destination etc )
-set the path of shell script directory in SM69 ( the command you just created )
-Execute shell script using your ABAP program ( use FM "SXPG_COMMAND_EXECUTE" )
In the ABAP program you can pass the parameters and execute the command from ABAP as a result your job will start printing on the required destination. Moreover, you can also capture the spool at OS level .
FYI
For UNIX script, if you search in www.google.com ( UNIX forums) . youll get shell script .
Hope thisll give you idea!!
P.S award the points.
Good luck
Thanks

How can I execute an .app remotely in a server via internet?

Hi,
Using PHP, or something like it, how can I execute a MAC OSX app but have it run remotely in the server?
I know this may sound like a simple question but I have almost no experience with Web apps.
Thanks,
Juan Dent

All you need is a trigger that starts the execution. A simple HTML link to the file will do.

How can I execute a batch file from my java program

Hi,
Can someone help me or direct me to a link,
How can I execute a DOS batch file from my java program?
Thanks

You will need to grab a handle to the process's
outputstream so u can see its output.The OP didn't mention any output from any batch file;
nor any input for that
matter,so lets not complicate matters here for now
ok?Actually I think this is essential to see whether it works or not. It's either that or do some manual check to see whether it ran, which is not exactly elegant, and in some cases this may not be easier than simply writing the output stream code, or in fact it may be impossible to check manually.
I'm sure it wasn't intentional that your post appeared to be bristling with attitude.
