Apache Axis2/Java Core

Apache Axis2/Java Core is a next-generation web services engine designed to support both SOAP and RESTful web services. It is the successor to Apache Axis 1.x, offering a more modular, efficient, and extensible architecture. Axis2 enables developers to build, deploy, and manage web services with improved performance and flexibility, supporting modern standards and formats including JSON and XML.

Features

• Support for SOAP 1.1, SOAP 1.2, and REST/POX interfaces
• Integrated JSON support via GSON and Moshi
• Hot deployment of services and handlers
• Lightweight XML object model (AXIOM) for high-performance message processing
• Streaming API for XML (StAX) parsing for speed and efficiency
• Modular architecture with plug-in modules for security and reliability
• WS-Security and WS-Addressing support via Apache Rampart and core modules

Capabilities

• Dual interface exposure: WS-* and RESTful services from the same business logic
• Dynamic service deployment without server restart
• Extensible module system for adding custom features
• Efficient memory usage and fast message parsing
• Java-based service development and client generation
• Compatibility with servlet containers and standalone deployment
• XML and JSON serialization/deserialization for flexible data handling

Benefits

• High performance and low memory footprint for enterprise applications
• Simplified development and deployment of web services
• Enhanced flexibility through modular design
• Seamless integration with existing Java applications
• Future-proof architecture supporting modern web service standards
• Ideal for organizations transitioning from SOAP to REST or JSON-based services
