javax.resource.spi.work.ExecutionContext Maven / Gradle / Ivy

This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).

/**
* This class models an execution context (transaction, security, etc)
* with which the Work instance must be executed.
* This class is provided as a convenience for easily creating
* ExecutionContext instances by extending this class
* and overriding only those methods of interest.
*
* Some reasons why it is better for ExecutionContext
* to be a class rather than an interface:
*
- There is no need for a resource adapter to implement this class.
* It only needs to implement the context information like
* transaction, etc.
*
- The resource adapter code does not have to change when the
*
ExecutionContext class evolves. For example, more context
* types could be added to the ExecutionContext class
* (in the future) without forcing resource adapter implementations
* to change.
*
* Note: Resource adapters that are developed for Jakarta Connectors specification
* compliant application servers, are recommended to use
* the TransactionContext interface instead of this
* class. See Chapter.11 Generic Work Context in the Connectors 1.6
* specification for more details.
