• HTTP Connector Abstractions - Provides multiple I/O connectors that abstract network protocol handling from the container.
• JNDI Resource Registrations - Registers JDBC connection pools and other resources in JNDI for lookup by deployed web applications.
• JSP Compilation Engines - Compiles JavaServer Pages into servlets at runtime or ahead-of-time for production deployment.
• Jakarta Annotations - Implements Jakarta EE annotations for resource injection, security roles, and persistence mappings in web applications.
• Security Providers - Authenticates users and authorizes roles using configurable realms, standard authentication methods, and Windows native integration.
• Security Realms - Authenticates users against configurable credential stores for container-managed security.
• Role-Based Access Control - Authenticates users against a database of credentials and roles to enforce container-managed security on web applications.
• TLS/SSL Configurations - Installs and configures SSL/TLS certificates to serve HTTPS traffic with optional OpenSSL acceleration.
• TLS Certificate Configuration - Apache Tomcat installs and configures SSL/TLS certificates so the server accepts encrypted connections using the https protocol.
• TLS Traffic Encryption - Secures HTTP requests by installing and configuring SSL/TLS certificates for HTTPS serving.
• Valve-Based Pipelines - Chains composable request-processing components in a pipeline for cross-cutting concerns.
• Dynamic Content Delivery - Compiles and serves JavaServer Pages, translating them into servlets for dynamic content delivery.
• Server-Side Page Compilers - Compiles JavaServer Pages into servlets at runtime or ahead of time for dynamic content generation.
• OpenSSL TLS Accelerations - Accelerates TLS connections using OpenSSL for improved performance.
• Static File Serving - Serves static files and generates directory listings through built-in servlets for unmatched requests.
• Annotation-Based Data Source Mappings - Associates data source definitions with classes or methods using Jakarta annotations for database connectivity.
• WebSocket Connections - Supports the WebSocket protocol for real-time, bidirectional communication between client and server.
• Session - Replicates session state across cluster nodes using delta requests for failover and load balancing.
• Virtual Host Managers - Adds and removes virtual hosts on a running server without restarting using the Host Manager web application.
• SNI-Based TLS Routers - Routes incoming TLS connections to different virtual hosts based on the SNI extension.
• HTTP/2 Support - Uses the HTTP/2 protocol for improved performance and multiplexed communication between clients and servers.
• Load Balancers - Distributes incoming requests across multiple server instances using a configurable load balancer.
• Application-Level - Distributes incoming HTTP requests across a cluster of server instances for load balancing.
• Proxy Servers - Routes incoming requests through a proxy server or web server acting as a proxy.
• Reverse Proxy Configurations - Routes requests through a front-end proxy while preserving client information and session state.
• APR Connectors - Leverages the Apache Portable Runtime for improved performance and OpenSSL integration.
• Ahead-Of-Time Compilation - Pre-compiles JSP pages into Java classes for faster startup and reduced runtime overhead.
• JSP Pre-Compilation - Pre-compiles JSP pages into Java classes for faster startup and reduced runtime overhead.
• Class Loader Hierarchies - Controls class loader visibility and ordering to resolve library conflicts between applications and the server.
• APR-Based Native Libraries - Leverages the Apache Portable Runtime for native I/O and OpenSSL-based TLS acceleration.
• CDI and JAX-RS Implementations - Apache Tomcat enables Contexts and Dependency Injection and RESTful web services through standard specifications.
• Standard Web Authentication Schemes - Authenticates users using BASIC, DIGEST, or FORM authentication methods.
• OpenSSL-Accelerated TLS - Uses the OpenSSL library for TLS encryption to improve connection throughput.
• Windows Native Authenticators - Integrates with Windows native authentication for single sign-on.
• Non-blocking I/O - Handles high-concurrency workloads with advanced I/O extensions that avoid blocking operations.
• JNDI Naming Contexts - Registers and resolves resources through an in-memory JNDI naming context scoped per web application.
• JMX Monitoring - Exposes server metrics and management operations through JMX for remote monitoring and administration.
• Server Side Includes Management - Processes Server-Side Include directives to insert dynamic content into static pages before serving.
