Specifying Liberty profile bootstrap properties

Bootstrap properties initialize the runtime environment for a particular server. Generally, they are attributes that affect the configuration and initialization of the runtime core.

• Use predefined properties to configure trace and logging.
  For example, change the name of your trace file by specifying the property com.ibm.ws.logging.trace.file.name in the bootstrap.properties file:

  com.ibm.ws.logging.trace.file.name = trace.log

  For a list of the predefined properties for trace and logging, see Liberty profile: Trace and logging.

• Use custom properties to define the default ports for web applications.

  You can share server.xml and use XML configuration files across various development environments that allow machine- or environment-specific customization. For example:

  1. Specify the properties default.http.port and default.https.port in the bootstrap.properties file:

     default.http.port = 9081
     default.https.port = 9444

     Note: If you do not specify the properties, the default HTTP port is 9080 and HTTPS ports is 9443. To override the default HTTP endpoint definition, set the id attribute of the httpEndpoint element to defaultHttpEndpoint in the server configuration.
  2. Use these properties in the server.xml configuration file:

     <httpEndpoint id="defaultHttpEndpoint"
     host="*"
     httpPort="${default.http.port}"
     httpsPort="${default.https.port}" />

     Note: host="*" means "listen on all adapters". By default, the server is listening only on address 127.0.0.1/localhost. You can also use the host property to specify a single IP address, and then the system listens only on the specified adapter.
• To apply the changes, restart the server.
