As discussed in the Nucleus-Based Application Structures section of the Developing and Assembling Nucleus-Based Applications chapter, each EAR file assembled by the runAssembler
command includes a web application named atg_bootstrap.war
. This module’s web.xml
file includes the tags necessary to configure the application to run an instance of Nucleus. This Nucleus instance is then available to any other web applications in the EAR file.
In addition to atg_bootstrap.war
, the EAR file typically includes one or more web applications that actually run your site. For example, the QuincyFunds.ear
file includes a web application named quincy.war
that runs the demo site. This application uses Nucleus components that implement Oracle ATG Web Commerce’s personalization features and are accessed in the application’s JSPs through the DSP tag libraries (described in the ATG Page Developer's Guide).
This chapter describes how you can access Nucleus in web applications by adding the necessary entries to the web application’s web.xml
deployment descriptor. For general information about web.xml
files, see the J2EE specifications.
