NonStop Servlets for JavaServer Pages (NSJSP)
Architecture
The ITP Secure WebServer software, which is inherently scalable and reliable, enables
the creation of Java Servlets that can take advantage of the database and transaction
services infrastructure of the HP NonStop server. Java Servlets run in a container that
is implemented as NonStop TS/MP server processes that can be replicated and
automatically load-balanced across multiple processor nodes for scalability throughput.
Consequently, large volumes of servlet-based web transactions can be executed
concurrently to maintain consistent response times.
