Configuring a module

The following are all the configuration options that can be specified in a .gwt.xml descriptor file:
GWT descriptor file element Purpose
<inherits name=”logical-module-name“/> Inherits all the settings from the specified module. There is no limit to the number of modules that can be inherited.
<entry-point class=”classname“/> Specifies an entry point class. There is no limit to the number of entry point classes that can be added. The onModuleLoad() for each of the entry point classes will be called one after the other in the in which they are listed here.
<source path=”path“/> Adds packages to the source path by combining the package in which the module XML is found with the specified path to a sub-package. Any Java source files appearing in the source path are assumed to be translatable.
If no <source> element is defined in a module XML file, the client sub-package is added to the source path by default.
<public path=”path“/> Adds packages to the public path by combining the package in which the module XML is found with the specified path to identify the root of a public path entry. Any files appearing in the public path will be treated as a publicly-accessible resource. The <public> element supports pattern-based filtering that allows you to control which resources get copied into the output directory during a GWT compile. It follows the same rules as Ant’s FileSet element.
If no <public> element is defined in a module XML file, the public sub-package is added to the public path by default.
<servlet path=”url-path” class=”classname“/> This element loads a servlet mounted at the specified URL path. This allows for convenient RPC testing. The URL path should be absolute and have the form of a directory, e.g. /example/path. Your client code then specifies this URL mapping in a call to ServiceDefTarget.setServiceEntryPoint(String). There is no limit to the number of servlets that can be loaded.
<script src=”js-url“/> Automatically injects the external JavaScript file located at the location specified. This is a convenient way of automatically associating external JavaScript files with your module.
<stylesheet src=”css-url“/> Automatically injects the external CSS file located at the location specified. This is a convenient way to automatically attach a CSS file to the HTML Host Page.
<extend-property name=”client-property-name” values=”comma-separated-values“/> Allows you to extend existing client properties with specified values. There is no limit to the number of values that can be added. Client property values accumulate through inherited modules. This element is particularly useful for specifying locales in internationalization.
