Liberty profile bootstrap.properties

The bootstrap.properties file initializes the runtime core environment for a particular server.

bootstrap.properties should reside in the server directory with server.xml...

wlp/usr/servers/worklightServer

For example...

c:/ProgramData/IBM/Worklight/WAS85liberty-server/wlp/usr/servers/worklightServer

Property types include...

• A small, predefined set of initialization properties.

• Any custom properties that you choose to define.

  We can then use these custom properties as variables in other configuration files such as server.xml and included files

We can edit bootstrap.properties with a text editor or using WebSphere Studio.

If we update bootstrap.properties, restart the server with the --clean option for the changes to take effect.

Trace and logging

We can change the name of the trace file by editing bootstrap.properties and specifying...

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

Define the default ports for web applications

We 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 bootstrap.properties:

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

   If we 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}" />

   host="*" means "listen on all adapters". By default, the server is listening only on address 127.0.0.1/localhost. We 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.
