commit 0f5b6d72e6891b220b884fb15a47d3640dd8cffa Author: Robert Lazarski <[email protected]> AuthorDate: Wed Apr 8 13:08:34 2026 -1000 Add MCP_EXAMPLES.md with live benchmarks and head-to-head C vs Java comparison New companion doc to Axis2/C MCP_EXAMPLES.md, showing identical financial demos (stress-test, pre-trade risk, convergence) run against Axis2/Java on WildFly 32. All curl commands have paired MCP stdio examples via the axis2-mcp-bridge JAR. Includes full performance summary: Java is ~2x slower on Monte Carlo, 2.8x on 500-asset PV, but produces identical financial results. Transport/timing note clarifies server-side calcTimeUs measurement. Also update jboss-deployment-structure.xml to dptv2 stable version (adds jdk.net module dependency needed for Apache HttpClient5 on WildFly 32).

This document shows the same live demos +as the Axis2/C `MCP_EXAMPLES.md`, run against the Java implementation, with +head-to-head performance numbers. + +The financial results are identical (same algorithms, same inputs, same outputs). +The implementations compete only on performance. + +--- + +## Transport and Timing Note + +Axis2/C is tested over **HTTPS/HTTP2** (`https://10.10.10.10/...` with TLS). +Axis2/Java is tested over **HTTP/1.1** (`http://localhost:8080/...` on WildFly). + +This does **not** affect the performance comparison. All timings in this document +use the **server-reported `calcTimeUs` field** — wall-clock time measured inside +the service handler, after request parsing and before response serialization. TLS +overhead occurs in the transport layer outside this measurement window. The +computation comparison is apples-to-apples. + +--- + +## Authentication + +Axis2/Java requires JWT authentication via Spring Security. All financial service +calls need a `Bearer` token obtained from the login endpoint: + +```bash +TOKEN=$(curl -s http://localhost:8080/axis2-json-api/services/loginService \ + -H 'Content-Type: application/json' \ + -d '{"doLogin":[{"arg0":{"email":"[email protected]","credentials":"userguide"}}]}' \ + | python3 -c "import sys,json; print(json.load(sys.stdin)['response']['token'])") +``` + +All subsequent examples assume `$TOKEN` is set. + +--- + +## API Differences: Java vs C + +The financial calculations are identical.
