If I want to add a constant that can be injected in one of xwork

adding @Inject and defining the constant in default.properties in core

Here's some simple examples:
Setup some beans and constants in the Container with unique names:
http://code.google.com/p/struts2urlplugin/source/browse/trunk/struts2-url-plugin/src/main/resources/struts-plugin.xml
eg. 1. Inject constant into a bean
http://code.google.com/p/struts2urlplugin/source/browse/trunk/struts2-url-plugin/src/main/java/com/blueskyminds/struts2/urlplugin/URLPatternActionMapper.java
Line 333
@Inject("struts.urlplugin.actionMapConfiguration")
public void setMappingConfigurationName(String
mappingConfigurationName) {
this.mappingConfigurationName = mappingConfigurationName;
}
eg. 2. Inject Container into a bean to enable run-time lookup by name
and class:
@Inject
public void setContainer(Container container) {
this.container = container;
}
Line 116
mappingConfiguration =
container.getInstance(ActionMapConfiguration.class,
mappingConfigurationName);
eg. 3. Inject Bean into another bean directly: exactly as per the
container injection. If there's only one instance it will bind,
otherwise specify the name, otherwise it will fail.
@Inject("defaultActionMapper")
public void setActionMapper(ActionMapper actionMapper) {...
It only gets complicated when you need to mix injection with beans
created outside the container, as described by Wes.

PS. this is far inferior to the current functionality of Guice.
