How to run the program using specific classpath

Recently I installed Javamail 1.2 and JAF1.0.1 on my NT Box and set up the classpath. I can compile my java email code by using: javac myEmail.java. But when I tried to run the code using java myEmail, it always gives the error: Exception in thread "main" java.lang.NoClassDefFoundError: myEmail.
when I use -verbose and found that it always goes to:
C:\Program Files\JavaSoft\JRE\1.3.1\lib\rt.jar to find classes even I use -cp option to point Javamail\mail.jar and activation.jar.
what is wrong with it? Thank you in advance!!!!!!

What does this have to do with JMS. I suggest that this should have been posted to the Java Programming forum where you would have gotten a quick response as this is a simple problem to diagnose.
The problem is that the class myEmail, which you created, is not on the class path so it cannot find it. It has nothing to do with the location of mail.jar and activation.jar, although this may cause problems later.
What you need to do is check the classpath in the environment variables section of the System dialog box. Make sure it refers to . (the current directory) as well as the locations of mail.jar and activation.jar. Also when you invoke myEmail ensure you are in the same directory.
Hope this helps

How to run the job using DBMS_SCHEDULER

How to run the job using DBMS_SCHEDULER
pleas give some sample Iam very new to DBMS_SCHEDULER

Hi
DBMS_SCHEDULER
In Oracle 10g the DBMS_JOB package is replaced by the DBMS_SCHEDULER package. The DBMS_JOB package is now depricated and in Oracle 10g it's only provided for backward compatibility. From Oracle 10g the DBMS_JOB package should not be used any more, because is could not exist in a future version of Oracle.
With DBMS_SCHEDULER Oracle procedures and functions can be executed. Also binary and shell-scripts can be scheduled.
Rights
If you have DBA rights you can do all the scheduling. For administering job scheduling you need the privileges belonging to the SCHEDULER_ADMIN role. To create and run jobs in your own schedule you need the 'CREATE JOB' privilege.
With DBMS_JOB you needed to set an initialization parameter to start a job coordinator background process. With Oracle 10g DBMS_SCHEDULER this is not needed any more.
If you want to user resource plans and/or consumer groups you need to set a system parameter:
ALTER SYSTEM SET RESOURCE_LIMIT = TRUE;
Baisc Parts: Job
A job instructs the scheduler to run a specific program at a specific time on a specific date.
Programs
A program contains the code (or reference to the code ) that needs to be run to accomplish a task. It also contains parameters that should be passed to the program at runtime. And it?s an independent object that can referenced by many jobs
Schedules
A schedule contains a start date, an optional end date, and repeat interval with these elements; an execution schedule can be calculated.
Windows
A window identifies a recurring block of time during which a specific resource plan should be enabled to govern resource allocation for the database.
Job groups
A job group is a logical method of classifying jobs with similar characteristics.
Window groups
A window groups is a logical method of grouping windows. They simplify the management of windows by allowing the members of the group to be manipulated as one object. Unlike job groups, window groups don?t set default characteristics for windows that belong to the group.
Using Job Scheduler
SQL> drop table emp;
SQL> Create table emp (eno int, esal int);
SQL > begin
dbms_scheduler.create_job (
job_name => 'test_abc',
job_type => 'PLSQL_BLOCK',
job_action => 'update emp set esal=esal*10 ;',
start_date => SYSDATE,
repeat_interval => 'FREQ=DAILY; INTERVAL=10',
comments => 'Iam tesing scheduler');
end;
PL/SQL procedure successfully completed.
Verification
To verify that job was created, the DBA | ALL | USER_SCHEDULER_JOBS view can be queried.
SQL> select job_name,enabled,run_count from user_scheduler_jobs;
JOB_NAME ENABL RUN_COUNT
TEST_abc FALSE 0
Note :
As you can see from the results, the job was indeed created, but is not enabled because the ENABLE attribute was not explicitly set in the CREATE_JOB procedure.
Run your job
SQL> begin
2 dbms_scheduler.run_job('TEST_abc',TRUE);
3* end;
SQL> /
PL/SQL procedure successfully completed.
SQL> select job_name,enabled,run_count from user_scheduler_jobs;
JOB_NAME ENABL RUN_COUNT
TEST_ABC FALSE 0
Copying Jobs
SQL> begin
2 dbms_scheduler.copy_job('TEST_ABC','NEW_TEST_ABC');
3 END;

How to run the program UMB_BSC_TABLE_CLEAN ?

Hi Friends,
I am getting a message telling inconsistency in the selection criteria while assigning the characteristic value in value fields of a measure of scorecard in SEM application. It's suggesting me to run the program "UMB_BSC_TABLE_CLEAN".
In the selection screen of "UMB_BSC_TABLE_CLEAN" apart from field for scorecard name there are 2 bullets - one for "Clean" and another for "Repair" and a checkbox named "Check".
Can anyone please tell me what are these selection screen options for ? Also to solve my problem how i'll run this program ?

From the documentation of the program:
Selection
Scorecard: select the scorecards whose database tables are to be cleaned or repaired.
Type of Table Change:
Clean Up:
Deletion of Scorecard elements that are no longer used or no longer need to be displayed
Deletion of value fields with value field selections that do not have a SAP BW counterpart
Repair
Restoration of inconsistent value field selections
Deletion of value fields for which the value field selections cannot be restored.
Check: If you set this indicator, all inconsistent entries are listed without changing the database table(s).

How to run the program in the applet

I have installed the JDK 1.3 and succesfully compiled my first Java application (appropriately named HelloWorld.java). I could compile the source file also.But i am getting an error when i am trying to run the program in the applet iam getting an error as
"start applet not initialised"
and the program is
* The HelloWorldApp class implements an application that
* displays "Hello World!" to the standard output.
public class HelloWorldApp {
public static void main(String[] args) {
// Display "Hello World!"
System.out.println("Hello World!");
so please help me out
Thanks in advance

Hmm... this is a console based application...
So it won't work using an applet viewer.
You can try coding an applet instead.
I hope I didn't misunderstand your question.

How to run batch programs using SUBMIT command without any interaction need

Hello ABAP gurus,
I have created a batch program in SE38 which calls many other SE38 Programs (Reports).
I have used the command SUBMIT to call the sub programs. There are about 15 sub programs that this main batch program is calling.
It works fine, but after calling each subprogram it stops and I have to manually click on 'Back Button' in green on the sap screen to run the next program in the list. Like this I have to do 15 times to run all the programs in the batch.
Is there a way to avoid this manual intervention and make the program run all the sub programs on its own.
Your feedback will be highly appreciated.
Thanks
Ram

Thanks Sampath for the response.
Yes I am using the option "AND RETURN". So it is coming out of each sub program, and it is at this stage it waits for me to click on 'backward green arrow' to continue to the next.
Here is the code I have used
SUBMIT Z_AS_BI_F0005_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_DIVISION_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_COMPANY_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_CUSTOMER_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_BRANCH_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_BUS_UNIT_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_ADDRESS_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_CUSTOMER_GROUP_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_GROUP_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_PMT_TERMS_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_REGION_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_TERRITORY_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
Any other suggestions or feedback will be appreciated.
Tks

Dear Friends,
I have a small problem, I want to run my labview program for specified amount of time, Say for example it might be 1 hour or 5 hours or 10 minutes or even milliseconds(The time will be specified by the user).
How to write programs for this
And I want to get the system time in an instance, how it can be achieved,
Could you please help me?
Regards,
Rathan

Hi,
Herewith my screenshot attached. There are thre inputs thres, tempX, xValue, it is in side the while loop.'xValue' will be acquired every iteration, It will be saved through shift register and acquired to 'tempX' for the next iteration, 'thres' is a constant value. I'm doing some logic, and calculating the dvalue and convert it to a string and concatenate it with end of line character, then after writing it into a file.
In the logic, inside of the functional logic I'm assigning some values dValue, if the logic is true or else dvalue will be 0
What I require is I don't want to write the dValue in to a file, if it is equal to zero. Could you please help me, how to tackle this problem?
Thanks.
