Enterprise Java Bean (EJB) based enterprise printing architecture

摘要

Features of Enterprise Java Bean (EJB), Enterprise Printing Bean (EPB), JAVA, J2EE, and document authoring are combined to enable a robust enterprise printing architecture. A Java object encapsulates a print job specification and provides a framework enabling access control to print jobs as well as providing audit capabilities. Print control languages can be specified using methods provided by the Java object. Actual process implementation can be supplied via a server enabling another layer of security and control. A user wanting to securely print a job supplies appropriate credentials to the print job bean to gain access to the content and print server credentials allow printing of the print job. The EJB API is extendable to enable all of the J2EE capabilities found on standard EJBs to be applied to print Jobs. Further, a new Java API provides a more powerful page description language than that found in other printing languages.
