Examples of org.apache.axis2.context.MessageContext

org.apache.axis2.context.MessageContext

Axis2 states are held in two information models, called description hierarchy and context hierarchy. Description hierarchy hold deployment configuration and it's values does not change unless deployment configuration change occurs where Context hierarchy hold run time information. Both hierarchies consists four levels, Global, Service Group, Operation and Message. Please look at "Information Model" section of "Axis2 Architecture Guide" for more information.

MessageContext hold run time information about one Message invocation. It hold reference to OperationContext, ServiceGroupContext, and Configuration Context tied with current message. For an example if you need accesses to other messages of the current invocation, you can get to them via OperationContext. Addition to class attributes define in Message context, message context stores the information as name value pairs. Those name value pairs,and class attributes tweak the execution behavior of message context and some of them can be find in org.apache.axis2.Constants class. (TODO we should provide list of supported options). You may set them at any level of context hierarchy and they will affect invocations related to their child elements.
