Axis Axis2 C Core

Apache Axis2/C

What is it? -----------

Apache Axis2/C is a web services framework written in C, for building and consuming JSON/REST and SOAP services. It is embeddable: the same engine runs as an Apache httpd module, inside a standalone server, or linked directly into an application binary.

It is written in C with no runtime beyond libc and its transport dependencies, which makes it usable where a managed runtime is not an option: as a module in an existing Apache httpd deployment, in embedded and resource-constrained environments, and on Android, where the build produces a native library and services are linked statically into the host process.

Features --------

• JSON/REST services over HTTP/1.1 and HTTP/2, with a JSON reader and

writer and a JSON-RPC message receiver.

• Runs as an Apache httpd module, as a standalone HTTP server, or embedded

in an application.

• Android and other static-linking targets. Service functions are declared

as weak symbols, so the framework compiles and links with no service implementation present and an application supplies strong implementations at link time. This is what allows services to be linked into a single native binary on platforms that do not load shared modules at runtime. configure detects an Android target and builds accordingly.

• Model Context Protocol (MCP) support, so deployed services can be called

as tools by an AI agent. Demonstrated in the financial-benchmark-service sample, with two transports: a JSON-RPC 2.0 stdio server for MCP clients that launch a subprocess, and an HTTP catalog endpoint that builds the tool list by walking the deployed services at request time. Tool descriptions, JSON Schema and the read-only, idempotent and destructive hints come from parameters in services.xml, so an existing service is exposed as an MCP tool by adding metadata rather than writing code.

• SOAP 1.1 and SOAP 1.2, built on the AXIOM XML object model, with complete

WS-Addressing 1.0 support and MTOM/XOP for binary attachments.

• One-way (In-Only) and request-response (In-Out) messaging, synchronous or

asynchronous.

• A code generator that produces C stubs and skeletons from WSDL.
