Java 6 API Programming on HP NonStop Servers

Course overview

This course prepares developers to deploy and/or port Java applications with JToolkit to a NonStop server. Topics include an overview of the Java language, an introduction to NonStop server for Java, coding client/server programs, accessing Pathway applications, Enscribe and NonStop SQL database access, JDBC, stored procedures, and debugging. The four-day course is 70 percent lecture and 30 percent hands-on labs using HP servers.
