Features

• Framework State Synchronizers - JRebel synchronizes state and refreshes configuration for popular libraries and frameworks during runtime updates.
• Dynamic Class Redefinition - Implements capabilities for replacing loaded classes in memory at runtime to update logic without restarts.
• Java Runtime Hot-Swapping - Updates compiled Java classes in a running application to apply code changes without restarting the process.
• Automatic Class Reloading - Automatically applies compiled Java class changes to the running application by monitoring the filesystem.
• Java Hot Swap Tools - Applies code changes to running Java applications instantly by monitoring compiled class files.
• Managed Bean Reinjections - JRebel refreshes session-scoped beans and context-managed components in a running application to reflect logic changes.
• Non-Code Resource Reloading - JRebel watches specified directories for changes to non-class resources and refreshes them in the running application.
• Post-Compilation Hot-Swapping - Triggers runtime updates automatically whenever a changed class is compiled by the build tool.
• Rapid Development Tools - Provides utilities to accelerate the development iteration cycle by automatically reloading classes and resources.
• Bean Instance Updating - JRebel reinjects dependencies or reloads bean instances after a class redefinition to ensure the latest code is active.
• Bean Registry Refreshing - JRebel updates components by re-scanning for classes and annotations at runtime to refresh the bean registry.
• Automatic Class Reloading - Watches the filesystem for modified class files and applies updates to the running application automatically.
• Component Instance Reloading - JRebel updates active instances of proxies, beans, and configurations immediately after their underlying classes are redefined.
• CDI Bean Redefinition - JRebel registers new bean classes and updates injection points and proxy factories at runtime to apply code changes.
• Component Configuration Redefinition - JRebel updates framework components and configurations at runtime without requiring an application restart.
• Classpath Extensions - Injects additional paths and external directories into the Java classpath during application execution.
• Runtime Instrumentation Agents - Modifies bytecode and redefines classes in a running Java Virtual Machine without restarting the application.
• Dynamic Dependency Injection - Refreshes managed beans and injection points at runtime to reflect updated logic in framework-based applications.
• Server Application Hot-Swapping - Modifies classes and web assets within a running server instance to avoid time-consuming application redeployments.
• Automatic - Clears internal caches, such as those used by Jackson, automatically when a class is redefined.
• Component - Clears definition and action caches automatically when classes are modified to ensure changes take effect.
• Metadata Caches - Clears internal metadata caches whenever a class changes to ensure the application uses the most recent definitions.
• SQL Mapper Reloading - JRebel updates MyBatis mapper configurations in real-time when files change to apply SQL mapping updates.
• Configuration Hot-Reloaders - JRebel applies changes made to supported configuration files in real time without rebooting the server.
• Development Asset Monitoring - JRebel monitors specific resource paths and file patterns to trigger actions upon file modification.
• Framework-Specific Reloading Mechanisms - Integrates custom plugins to implement framework-specific reloading mechanisms for specialized application components.
• Hot-Patching Tools - Allows application logic to be updated at runtime without requiring a process restart or active debugging session.
• IDE Integrations - Provides connectors that link the runtime agent to development environments to trigger reloads.
• Persistence Factory Reloading - JRebel refreshes the persistence factory and reloads configuration when entity classes change.
• Reloading Hooks - Allows the definition of custom reloading hooks and service registrations for specific application frameworks.
• Properties File Reloading - JRebel clears the cache of properties files automatically upon modification to apply text and configuration changes.
• Template Model Refreshing - JRebel updates template models in real time so that changes are reflected in the browser immediately after a page refresh.
• UI Template Updating - JRebel updates template models and clears internal metadata caches upon class modification to ensure changes appear in the browser.
• Dynamic Configuration Reloading - JRebel updates web application directories and classpath settings at runtime to reflect code changes in servers like Undertow.
• Agent Functionality Extensions - Modifies runtime behavior by annotating classes and configuring package discovery to create custom plugins.
• Persistence Factory Reloading - JRebel refreshes session factories when entity classes change to apply new schema or mapping definitions.
• Anonymous Class Resolution - Tracks class state via reflection and filesystem analysis to resolve index shifts when modifying anonymous classes.
• API Resource Redefinition - Redefines root resource and provider classes at runtime so API changes take effect without restarting.
• Proxy Class Redefinitions - JRebel updates synthetic classes generated by reflection at runtime so changes take effect without restarting.
• REST Service Redefinition - Hotswaps REST service definitions, updating active resource classes and data contexts without restarting.
• Runtime Agent Attachment - Allows connecting the instrumentation agent to a Java process while it is already running.
• Runtime Configuration Management - Enables updating logging, mapping, and property files in a live environment without requiring a system reboot.
• Dynamic Configuration Reloading - JRebel watches logging configuration files for changes and triggers a full reconfiguration automatically.
• Resource Registry Refreshing - Cleans and re-registers class definitions within a resource registry to apply code changes without restarting.
• Static Resource Refreshing - JRebel monitors directories for modified resource files and serves updated versions to the application immediately.
• Dynamic Route Updating - Registers changes to route definitions when classes are modified to add new views without a restart.
• Development Utilities - Unlimited runtime class and resource redefinition.
• Runtime Management Tools - Redefine classes at runtime without redeployment.
