Run Xebra Server
- Note that you should have compiled the translator before you run the server.
- If you have not done so, open the file $XEBRA_DEV/eiffel_projects/xebra_server/config.ini and adapt translator, compiler, and webapps_root to your configuration (see Xebra Server Config File).
- Launch estudio and compile the project $XEBRA_DEV/eiffel_projects/xebra_server/xebra_server-voidunsafe.ecf
- Go to the Execution -> Exceptions Handling dialog. Check "Filter Exceptions?" and change DEVELOPER_EXCEPTION to "Ignore"(this is due to a bug in the NET library that has not been fixed yet).
- Open the Execution -> Execution Parameters dialog and set "config.ini -d 10" as argument (see below for more info about run arguments).
- Compile and run
- Browse to http://localhost:55000/helloworld/. The server now translates, generates, compiles and finally runs the helloworld application.
Modules
The server automatically launches the following modules:
- mod_http: Listens to requests from the http plugin (Apache Module or IIS7 Handler) on port 55001. These request are forwarded to the appropriate webapp.
- mod_console: Reads input from the console. The commands described below can be invoked.
- mod_cmd: Listens to command request from the webapps on port 55002.
Webapps
Assume webapps are running
If assume_webapps_are_running was set, the server does not translate, compile and run the webapps. It just tries to connect immediately. This should be used when a webapp is launched in estudio for debugging and the server should not try to run and shutdown the webapp.
Development Mode
By default, a webapp is set to Development Mode which means that the server checks everytime a request was made if the webapp needs to be retranslated and compiled. This makes access to the webapp very slow. As soon as development of the webapp stopps, dev_mod should be set to off.
Fire off a webapp
If the server crashed and therefore could not properly shut down all webapps, they will still be running when the server is relaunched. Hence, the socket will be occupied when the server tries to launch a webapp. Use the fire command to fire off a possibly running webapp. The fire command tries to directly connect to the webapp and send a shutdown signal regardless if the webapp process is owned by the server or not.
Config File
Run Arguments
USAGE: xebra_server <config_filename> [-d <debug_level>] [-c] [-r] [-v] OPTIONS: -d --debug_level : Specifies a debug level. 0: No debug output. 10: All debug ouput. (Optional) -c --clean : If set, all webapps will be cleaned (Optional) -r --assume_webapps_are_running: If set, the server assumes that the webapps are already running and does not translate, compile and run them before connect to them. (Optional) -h --help : Display usage information. (Optional) -v --version : Displays version information. (Optional) ARGUMENTS: <debug_level>: The debug level (0-10) NON-SWITCHED ARGUMENTS: <config_filename>: The path of the config.ini file to use.
