Port springbootdemo to Apache Tomcat 11 and fix transport-h2 parameter parsing
Add springbootdemo-tomcat11: copy of the WildFly 32 JSON/Spring Boot demo ported to Apache Tomcat 11.0.20, targeting Axis2 2.0.1-SNAPSHOT. Removes WildFly-specific deployment descriptors (jboss-deployment-structure.xml, jboss-web.xml), excludes DataSource/JPA auto-configuration (not needed — demo DAO is in-memory), and documents Tomcat 11 HTTP/2 setup via <UpgradeProtocol> in server.xml. Also fix bugs found during Tomcat testing that affect both demos: - H2TransportSender: all five getXxxParameter helpers called param.toString() on the Parameter object, producing "Parameter : name=value" instead of the value; fixed to call param.getValue().toString() - bigdata_h2_resources/services.xml: wrong message receiver class (org.apache.axis2.json.JSONMessageReceiver, non-existent) and wrong Spring object supplier package (org.apache.axis2.spring vs org.apache.axis2.extensions.spring.receivers); both corrected - BigDataH2Service.java: three lossy long-to-int conversions on getDatasetSize() division result; added explicit (int) casts - BigDataH2Client.java: HTTPConstants.TRANSPORT_NAME/HTTP_CLIENT_VERSION/ HTTP_CLIENT_5_X moved/renamed in 2.0; updated to string literal and HTTPTransportConstants equivalents; import fixed from transport.http to kernel.http - ESAPI.properties: SafeString regex lacked underscore/hyphen; fixed pattern to ^[\\.\\p{Alnum}\\p{Space}_\\-]{0,1024}$ (double-escaped backslashes required for Java Properties parsing) Add json-springboot-tomcat11-userguide.xml: site doc based on the WildFly guide, documenting Tomcat 11 differences, HTTP/2 <UpgradeProtocol> config, and correct cp -r deploy procedure for the exploded WAR directory.

Enterprise Big Data Processing Service with HTTP/2 Transport Optimization
25+
26+
This service demonstrates HTTP/2 transport capabilities for large JSON datasets:
27+
- Support for 50MB+ JSON payloads with streaming optimization
28+
- Connection multiplexing for concurrent request processing
29+
- Memory-efficient processing within 2GB heap constraints
30+
- Performance monitoring and optimization metrics
31+
32+
Transport Features:
33+
- HTTP/2 streaming for large datasets (50MB+)
34+
- Connection multiplexing for medium datasets (10-50MB)
35+
- Standard HTTP/2 processing for small datasets (&lt;10MB)
36+
- Memory pressure handling and adaptive flow control
37+
38+
Security Features:
39+
- OWASP ESAPI input validation
40+
- HTTPS-only endpoint enforcement
41+
- Enterprise security compliance
