WSO2 Carbon kernel, the lean, modular, OSGi-based platform, is the base of the WSO2 Carbon platform. It is a composable server architecture which inherits modularity and dynamism from OSGi framework. WSO2 Carbon kernel can be considered as a framework for server development. All the WSO2 products are composed as a collection reusable components running on this kernel. These products/components inherits all the core services provided by Carbon kernel such as Registry/repository, User management, Transports, Caching, Clustering, Logging, Deployment related features. An open source product, WSO2 Carbon is available under the Apache Software License (v2.0) <http://www.apache.org/licenses/LICENSE-2.0.html> What's New In This Release - New Distributed Caching implementation based on Hazelcast. - New Clustering implementation based Hazelcast. - Synchronous deployment of CApp artifacts to ensure the atomicity of a CApp. - Improved Patches and Service packs installation model - Multi-profile support at the Carbon platform which enables a Carbon based product to behave in multiple modes/profiles - Feature Categorization - Various bug fixes & enhancements<https://wso2.org/jira/browse/CARBON/fixforversion/10781#selectedTab=com.atlassian.jira.plugin.system.project%3Aversion-issues-panel>including stabilizing WSO2 Carbon Kernel. Key Features - Composable Server Architecture - Provides a modular, light-weight, OSGi-based server development framework. - Carbon Application(CApp) deployment support. - Multi-Profile Support for Carbon Platform - This enable a single product to run on multiple modes/profiles. - Carbon + Tomcat JNDI Context - Provide ability to access both carbon level and tomcat level JNDI resources to applications using a single JNDI context. - Distributed Caching and Clustering functionality - Carbon kernel provides a distributed cache and clustering implementation which is based on Hazelcast- a group communication framework - Pluggable Transports Framework - This is based on Axis2 transports module - Registry/Repository API- Provide core registry/repository API for component developers - User Management API - Provides a basic user management API for component developers - Logging - Carbon kernel supports both Java logging as well as Log4j. Logs from both these sources will be aggregated to a single output - Pluggable artifact deployer framework - Kernel can be extended to deploy any kind of artifacts such as Web services, Web apps, Business processes, Proxy services, User stores etc. - Deployment Synchronization - Provides synchronization of deployed artifacts across a product cluster. - Ghost Deployment - Provides a lazy loading mechanism for deployed artifacts - Multi-tenancy support - The roots of the multi-tenancy in Carbon platform lies in the Carbon kernel. This feature includes tenant level isolation as well as lazy loading of tenants. *Fixed Issues in This Release* WSO2 Carbon 4.2.0 release comes with number of bug fixed and improvements on Carbon framework, - Fixed issues on WSO2 Carbon<https://wso2.org/jira/browse/CARBON-14098?filter=11284> *Known Issues* All known issues on WSO2 Carbon have been recorded at, - Known issues on WSO2 Carbon<https://wso2.org/jira/browse/CARBON-14406?filter=11299> *Reporting Problems* Issues can be reported using the public JIRA available at https://wso2.org/jira/browse/CARBON *Contact us* WSO2 Carbon developers can be contacted via the mailing lists: *Carbon Developers List:* [email protected] *Carbon Architecture List:* [email protected] For details on subscriptions see http://wso2.org/mail *Wiki:* http://docs.wso2.org/wiki/display/Carbon420/WSO2+Carbon+Documentation *Support* WSO2 Inc. offers a variety of development and production support programs, ranging from Web-based support up through normal business hours, to premium 24x7 phone support.
