# Deploying the Web Application

You will need to update the src/main/resources/applications.properties to include your DB connection information.

The configuration defined in application.properties can also be passed as command line arguments. The priority of property loading is as follows:

1. -D command line parameters overrides all
2. src/main/resources/application.properties
3. application.properties supplied at compile time
4. Defaults defined in code

Note that the authenticate property is currently required to be set as a command line argument, it won't work when set in application.properties (See issue #6109).

Some scripts require a ${PORTAL_HOME}/application.properties file, so it is best to define the properties there.

For more information about the application.properties file, see the reference page.

To run the backend execute the following commabd

java -jar target/cbioportal-exec.jar

This runs the app in the foreground. If a port is already in use it will raise an error mentioning that. To change the port use the --server.port flag.

There are three main ways to run the portal: without authentication, with optional login, and with required login. All of them require the cBioPortal session service to be running.

In this mode users are able to use the portal, but they won't be able to save their own virtual studies and groups.

java -jar target/cbioportal-exec.jar -Dauthenticate=false

To configure the authentication and authorization please consult the Authorization and Authentication Sections.
