The JobScheduler can be controlled by commands (e.g. starting a jobs) from external applications (or scripts).
More information of all available commands can be found here: Jetty/xml_commands.xml Command List].

...

An external application, which is able and has the authorisation to send such commands to the JSEngine can use http(s) or tcp/ip to establish the communication. That means, that even a script language like javascript can be used to communicate. For Java users we have a wrapper class paket which was created using JAXB and the xsd schema for the commands and answers.

...

Protocols

The commands can be transferred to the JobScheduler via the following protocols:

httpHTTP
httpsHTTPS
tcpTCP
udpUDP

and telnet.

In addition a cli command line interface (CLI) is available via the "jobscheduler.sh" script.

Example using JOC

You can use JOC to send a command using the URL:

Code Block
http://[scheduler_host]:[scheduler_port]/<span style="color:red;"><show<show_state/></span>>

or if you open JOC with [How_to_run_JobScheduler_with_ Jetty then type:

Code Block
http://[scheduler_host]:[jetty_port]/jobscheduler/engine-cpp/<span style="color:red;"><show<show_state/></span>>

where <span style="color:red;"><show<show_state/></span> > is an example for a command of the JobScheduler external API.

Example using the JobScheduler script

You can use the startscript found in "./bin" to send a command too.
An example for using the command line option

Code Block
jobscheduler.sh command "<span style="color:red;"><show<show_state/></span>>"

The answer of jobscheduler.sh command ... is without indent and newlines.
If you want a more readable answer then type

Code Block
jobscheduler.sh command "<span style="color:red;"><show<show_state/></span>>" \| sed -e 's;[^>]*$;;' \| xmllint --format -
