No More Waiting for WebLogic Hot Deploys, WildFly Hot Reloads, and Legacy Java App Server Restarts
Developing Java applications just got a lot faster. With JRebel, developers can skip WebLogic hot deploy cycles, WildFly hot reload waits, and Tomcat hot deploy delays, all without restarting the server.
Back to topSkip the Rebuild-Restart-Redeploy Loop, No Matter Which App Server You Run
Building Java applications shouldn't mean watching progress bars. JRebel is a Java deployment tool that allows you to see code changes the moment you save — class updates, resource files, framework configs — live, without losing application state.
This remains true during a WebLogic migration, WebSphere migration, Hybris migration, or JBoss migration. JRebel installs the same way in a new environment, so your team's deployment speed doesn't drop while the migration is underway.
Instant Java Hot Reloads and Java Redeploys Across Your Application Server Stack
Many enterprise applications remain on established application servers because stability matters. Improve developer productivity by reducing restart cycles and supporting faster feedback across existing Java environments with JRebel.
Whether you're supporting WebLogic hot deploy, validating changes during a WebSphere migration, or maintaining a WildFly hot reload workflow, JRebel fits into the environments developers use every day.
Update Running Apps Without Full Java Redeploys
Redeploys can cost hours of valuable development time every week on legacy Java app servers. Skip redeploys and accelerate time-to-market with JRebel. This faster workflow is especially valuable for teams working with legacy enterprise servers where deployments are traditionally expensive.
- Reduce deployment interruptions
- Improve Java EE hot reload workflows
- Minimize unnecessary application restarts
- Keep developers focused on development, instead of deployment
Keep Your Application Running Between Code Changes
Maintaining application state removes one of the biggest sources of lost development time. JRebel keeps applications running during supported code updates, allowing developers to continue testing without recreating sessions, navigating back through workflows, or rebuilding application state after every deployment.
- Continue testing from current points
- Cut down repetitive setup work
- Validate changes faster
- Boost debugging efficiency across applications
Works Wherever You Deploy
Work faster on your chosen application server — locally and in the cloud. Whether you're maintaining long-running applications or modernizing legacy platforms, JRebel fits into your current stack without requiring teams to replace their preferred IDEs, build tools, or application servers.
- Configure WildFly hot reloads for core enterprise applications, or streamline a JBoss migration by testing code adjustments on the fly
- Implement Tomcat hot deploy or Tomcat hot reload workflows to avoid invalidating a session state during rapid development
- Full support for Java EE hot deploys and reloads across legacy app servers like WebSphere Liberty, GlassFish, SAP NetWeaver, and Oracle OC4J
Keep Redeploys Fast During Migrations
A WebLogic migration, WebSphere migration, Hybris migration, or JBoss migration shouldn't reset your team's deployment speed back to zero. JRebel installs into the new environment easily, reducing unnecessary restarts to shorten each validation cycle and keep developers focused on solving problems.
- Install the same way in a new environment as it would in the old one
- Keep redeploy times, such as Tomcat hot deploys, consistent through a migration
- Avoid the slow deployment cycles that often accompany app server migrations.
Works Wherever You Code
JRebel works across every major Java IDE.
- IntelliJ IDEA, Eclipse, and VS Code (including VS Code forks like Cursor, Windsurf, and Antigravity) — locally or in the cloud.
- Fully compatible with JetBrains IntelliJ, including remote development via JetBrains Gateway.
- Integration with your existing Java IDE workflows and IntelliJ Ultimate configurations.
Frequently Asked Questions
Yes. JRebel supports Oracle WebLogic through its application server integration, helping developers reduce full redeploys and shorten development cycles during everyday work and WebLogic migration projects.
Yes, JRebel supports WildFly and JBoss EAP directly. JRebel reloads changes into the running instance instead of restarting it. That support carries through a JBoss migration as well, so a move to a new environment doesn't slow deployment down.
JRebel supports many enterprise Java application server environments, including Oracle WebLogic, IBM WebSphere, WebSphere Liberty, SAP Commerce (Hybris), JBoss EAP, WildFly, Apache Tomcat, and GlassFish, alongside popular IDEs, frameworks, and build tools.
Yes, JRebel supports WebLogic, WebSphere, WildFly, and Tomcat hot reloads and redeploys in remote and cloud setups.
