Running job in batch from java

Hi

I have a job which is submitted on AS400 in batch from
java,
So I have to write a java class which will submit this
job and then wait till the job is over on AS400, 
This is my code which keeps in loop checking for
status
// code to call a CL job and get the submitted job
number here
Job myJob = new Job(as400, jobNumber, jobUser,
newJobNum);
String jobStatus = myJob.getStatus();
System.out.println("Job status before " + jobStatus);
while (!jobStatus.equals("*ACTIVE"))
{
myJob = new Job(as400, jobNumber, jobUser, newJobNum);
jobStatus = myJob.getStatus();
}

this job runs for about 5 min, and I think that if I
keep on running this loop for 5 min it will consume a
lot of server resources,

so I want to write a program which will sleep for 1
min before checking the job status.

Can  anyone provide me some clue or code on how to do
it
Ashish
