Declaration of the initial context model state together including context entry key/value bindings. A context directive typically contains a series of <entry> directives where each directive asserts a default inital value for a context entry key. Any required context entry declared by a component must be associated with a context entry directive. Failure to provide context entry directives for all required context keys will result in a deployment failure.
entry | The entry element may contain 0..n nested <entry> directives. A entry directive allows the creation by (value or reference) of a value associated with a context entry key. |
context | If the context entry return type is itself a context interface then the context element may be supplied as the value solution. |
map | Nested entries are used to construct an instance of java.util.Map. If the entry class attribute is not null, the constructed map will be used as a constructor argument to the class declared by the class attribute. |
The following example demonstrates a variety of context entry directives including the usage of symbolic values, static field references, direct value creation, composite value creation, and service wiring.
<context> <entry key="name" value="${user.name}"/> <entry key="printer" lookup="org.acme.Printer"/> <entry key="background" method="RED"/> <entry key="foreground"> <param class="float" value="100"/> <param class="float" value="200"/> <param class="float" value="0"/> </entry> <entry key="widget" class="org.acme.DefaultWidget"> <param class="org.acme.DefaultGizmo"> <param class="float" value="0"/> <param class="int" value="1024"/> </param> </entry> </context>
