Important Services 

The most important services of the J2EE Engine are outlined here. For each service there is a link to detailed documentation.

You can find all the services in the Visual Administrator. Choose Dispatcher or Server ® Services.

HTTP Provider Service

The HTTP Service makes the low-level communication and transport layer for the Web container available to the SAP J2EE Engine. The HTTP service implements the HTTP 1.1 protocol.

Here you define the port on which the J2EE Engine will receive HTTP requests. The standard port is 50000. You can manage caching, set up load balancing, define timeouts, etc.

The HTTP provider also supports virtual hosting.

For more information on the HTTP provider see HTTP Provider Service

Web Container Service

The Web container is a service that supports the processing of servlets and Java Server Pages (JSP). These are technologies for creating application HTML pages online. In the Visual Administrator the service displays which servlets and JSPs are installed and allows certain changes to be made to the configuration of these programs.

For more information on the HTTP Provider see Web Container Service

EJB Container

Enterprise Java Beans (EJB) is a J2EE Standard technology, and allows isolated objects to be processed in a container. This isolation makes objects more stable and robust. The EJB container can display all the contained EJBs and some of their settings in the Visual Administrator. To change their configuration, all EJBs must be reinstalled (deploy).

For more information on the HTTP Provider see EJB Container Service

Security Services

The most important services that are needed for security purposes include:

 

·        Security Provider

·        <0} Key Storage

Use this service to maintain the J2EE Engine’s security information for cases where you use cryptography, for example, when using the Secure Sockets Layer (SSL) protocol

·        SSL Provider

This service handles the communications when SSL is used for securing connections.

For more information on the HTTP Provider see: SAP J2EE Engine Security.

Monitoring Services

The Monitoring Service of the SAP J2EE Engine collects the monitoring data from the J2EE Engine. Within the J2EE Engine the monitored resources and attributes are displayed together with alerts in the Monitoring Service. This type of resource monitoring is especially suitable for test and development systems.

The monitoring data is also transferred to the CCMS if the appropriate connection is available. We recommend that you use the CCMS to monitor a production application server.
