No Native Code. No JNI. No Platform Headaches.

JDeli is a pure Java image library solution that won't cause extra work.

Problems with most Java image libraries

Most Java image libraries are actually JNI wrappers around native C/C++ libraries, which can cause deployment, compatibility, and maintenance headaches.

Native Libraries Can Break Across Platforms

You use a popular image library like ImageMagick, which is C-based and accessed from Java via JNI. You now need to install native binaries (.dll/.so/.dylib). When deploying to a new server or cloud environment (like AWS Lambda, Docker, Kubernetes), the app crashes because the native library isn't installed, the library version doesn't match, and the OS version isn't compatible.
You’re using a JNI wrapper for a C/C++ library. However, native code can cause segmentation faults. One small memory bug in C/C++ can crash the whole JVM, taking down your server. Not to mention that debugging these crashes is much harder than debugging pure Java exceptions.

JNI Bugs Can Crash the JVM

Harder to Package and Deploy on Different Platforms

You package your app as a Spring Boot .jar or as an AWS Lambda function. Now you can’t ship just one .jar, because you need a complicated build process to bundle native binaries, platform-specific installers, and a more complex CI/CD pipeline.
You update your JDK from Java 17 to Java 21. Then you realize the JNI binding or native library no longer works and you need to rebuild or update native binaries for the new JDK. Java’s forward compatibility breaks because of external native dependencies.

Updates and Maintenance Pain

We replaced all our various image processing code with JDeli, which allowed us to smoothly migrate to Java 11. The support from IDR solutions is just great. Whenever we came across a strange image from our customers which JDeli couldn't read properly, IDR fixed it in less than a day.

Security

While other Java image libraries may bring security risks caused by native codes, JDeli benefits from the JVM's safety mechanisms (bounds checking, sandboxing) as it's a pure Java solution.

Portability

JDeli runs on any platform with a JVM and there's no need to compile native libraries for different platforms or architectures.

No Native Dependencies

No JNI glue code is needed. JDeli solves issues with incompatible native libraries, version mismatches, or missing DLLs/SOs.

Easier Deployment

JDeli package everything in a single .jar or .war file. You don't need to download special installers, or worry about native library paths.

Ease of Maintenance

It's relatively easier to debug and maintain your Java project if it uses a single language for the whole stack.

Future Proof

Native libraries can break with new OS versions or JVM updates. JDeli is more likely to stay compatible across JVM updates.
