EspressReprt has a number of different configurations in which it can run at design-time and at run-time.  The diagram below shows a sample layout for application/applet and servlet/JSP configurations.

EspressReport deployment can be as simple as including some API classes in servlet/JSP code.  The Report API can retrieve data from enterprise data sources and run reports using pre-defined templates created in the Report Designer.

EspressManager is not required to deploy reports, but is needed if user's are deploying the scheduler component with their applications.  EspressManager can run as a background process, a Windows service, or deploy as a servlet collection in most application servers/servlet containers.

EspressReport can also generate reports on headless Unix systems.  Using either Java 1.4 headless, the PJA Toolkit from eTeks, or XVFB, EspressReport can add dynamic reporting to applications regardless of platform.
