Java as a batch job

[neltan]

Hi java user,

Q1. I would like to synchronize data from mssql to postgresql in a schedule job. I did this by VB use Windows scheduler. Can java do this also? OS may be Linux or Window.

Q2. Can jsp ask OS to run this scheduler immediately? Is there any API for jsp to request OS performing the action?

Q3. Any new technology that make java generate exe like VB, that do not need java runtime?

Thanks !!

Answer: You can run a Thread which will wait for a certain time period and then run the process again.

Q2. Can jsp ask OS to run this scheduler immediately? Is there any API for jsp to request OS performing the action?
Answer: Yes you can do this using the Thread. Instantiate the thread and then call the start method

Q3. Any new technology that make java generate exe like VB, that do not need java runtime?
