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 Jetty then type:

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

where <show_state/> 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 "<show_state/>" \| sed -e 's;[^>]*$;;' \| xmllint --format -
