Editing the Liberty configuration by using developer tools

You can modify the behavior of Liberty by editing the configuration. For example, you can configure which HTTP ports to use, what features are enabled, and logging and tracing settings.

Before you begin

For a description of the underlying process of configuring a server, and detailed information about specific aspects of server configuration, see Administering Liberty manually.

About this task

The server configuration editor consists of two views: the Source view and the Design view. The Design view is a structured view of the file whereas the Source view is a text view. But both of them are views of the same server configuration file. The Design view has many features that help with the construction of some of the more complex elements in the server configuration such as data sources.

The following steps are demonstrated in the Design view.

Procedure

  1. To open the Server Configuration editor, select any of the following options:
    • In the Servers view, right-click the server configuration and select Open.
    • In the Enterprise Explorer view, expand your server project and the server folder. Right-click the server.xml file and select Open.
    Here is a screen capture of the server configuration editor:

  3. Under the Feature Manager section, the details for the currently selected element are displayed. The details can also be modified here.
  4. To add new elements, select Server Configuration under the Configuration Structure section then click Add.
