Integrating systems for a J2EE Application involves assembling the individual J2EE Modules representing the Implementation Subsystems into a J2EE Application. The resulting archive represents the System Build. For more information on Builds for J2EE Applications, see Guideline: Builds for J2EE Applications.

The assembly of the individual Implementation Subsystem J2EE Modules requires some reconciliation between these modules, and the results of the integration are captured in the resulting J2EE Application and deployment descriptor. For more information on assembling J2EE Applications, see Guideline: Assembling J2EE Applications.

The resulting archive and deployment descriptor then serve as input to system integration testing.
