== The APEX REST Editor
The standard way to use the APEX REST Editor is via an installation of the __war__ file on a webserver.
However, the REST editor can also be started via command line.
This will start a Grizzly webserver with the __war__ deployed.
Access to the REST Editor is then via the provided URL 

On UNIX and Cygwin systems use:

- `apexRESTEditor.sh` - simply starts the webserver with the REST editor
- `apexApps.sh rest-editor` - simply starts the webserver with the REST editor

On Windows systems use:

- `apexRESTEditor.bat` - simply starts the webserver with the REST editor
- `apexApps.bat rest-editor` - simply starts the webserver with the REST editor


Summary of alternatives to start the APEX REST Editor:

[width="100%",options="header",cols="5a,5a"]
|====================
| Unix, Cygwin | Windows
|
[source%nowrap,sh]
----
# $APEX_HOME/bin/apexRESTEditor.sh.sh [args]
# $APEX_HOME/bin/apexApps.sh rest-editor [args]
----
|
[source%nowrap,bat]
----
> %APEX_HOME%\bin\apexRESTEditor.bat [args]
> %APEX_HOME%\bin\apexApps.bat rest-editor [args]
----
|====================

The option `-h` provides a help screen with all command line arguments.

[source%nowrap,sh]
----
usage: org.onap.policy.apex.client.editor.rest.ApexEditorMain [options...]
-h,--help                        outputs the usage of this command
-l,--listen <ADDRESS>            the IP address to listen on.  Default value is localhost to restrict access to the
                                 local machine only.
-p,--port <PORT>                 port to use for the Apex RESTful editor REST calls.
-t,--time-to-live <TIME_TO_LIVE> the amount of time in seconds that the server will run for before terminating. Default
                                 value is -1 to run indefinitely.

If the REST Editor is started without any arguments the final messages will look similar to this:

[source%nowrap,sh]
----
Apex Editor REST endpoint (ApexEditorMain: Config=[ApexEditorParameters: URI=http://localhost:18989/apexservices/, TTL=-1sec], State=READY) starting at http://localhost:18989/apexservices/ . . .
Sep 05, 2018 11:24:30 PM org.glassfish.grizzly.http.server.NetworkListener start
INFO: Started listener bound to [localhost:18989]
Sep 05, 2018 11:24:30 PM org.glassfish.grizzly.http.server.HttpServer start
INFO: [HttpServer] Started.
Apex Editor REST endpoint (ApexEditorMain: Config=[ApexEditorParameters: URI=http://localhost:18989/apexservices/, TTL=-1sec], State=RUNNING) started at http://localhost:18989/apexservices/
----

The last line states the URL on which the REST Editor can be accessed.
The example above stated `http://0.0.0.0:18989/apex/`.
In a web browser use the URL `http://localhost:18989` and the REST Editor will start.
