Component

Components in the Carbon platform add functionality to all WSO2 Carbon-based products. For example, the statistics component enables users to monitor system and service level statistics. A component in the Carbon platform is made up of one or more OSGi bundles, which is the modularization unit in OSGi similar to a JAR file in Java. For example, the statistics component contains two bundles: one is the back-end bundle that collects, summarizes, and stores statistics, and the other is the front-end bundle, which presents the data to the user through a user-friendly interface. This component-based architecture of the WSO2 Carbon platform gives developers flexibility to build efficient and lean products that best suit their unique business needs simply by adding and removing components.

Port offset

The port offset feature allows you to run multiple WSO2 products, multiple instances of a WSO2 product, or multiple WSO2 product clusters on the same server or virtual machine (VM). The port offset defines the number by which all ports defined in the runtime such as the HTTP/S ports will be offset. For example, if the HTTP port is defined as 9763 and the portOffset is 1, the effective HTTP port will be 9764. Therefore, for each additional WSO2 product, instance, or cluster you add to a server, set the port offset to a unique value (the default is 0).

Port offset can be passed to the server during startup as follows:
./wso2server.sh -DportOffset=3

Alternatively, you can set it in the Ports section of <PRODUCT_HOME>/repository/conf/carbon.xml as follows:
<Offset>3</Offset>

SOAP

An XML-based, extensible message envelope format, with "bindings" to underlying protocols. The primary protocols are HTTP and HTTPS, although bindings for others, including SMTP and XMPP, have been written.

WSO2 Carbon

WSO2 Carbon is the component-based, service oriented platform on top of which the WSO2 products are built. Carbon consists of a collection of OSGi bundles as Carbon components for security, clustering, logging, statistics, management and more. You can build products simply by plugging various Carbon components together using the WSO2 Carbon component manager.

WSO2 CEP Management Console

WSO2 CEP Management Console is a Web based control panel powered by JSP and AJAX which enables system administrators to interact with a running CEP instance without touching any underlying configuration files. The Management Console allows the users to command and control proxy services, sequences, transports, local entries, registry, modules, endpoints and much more.
