This is a Java based implementation of Hyprledger Fabric chaincode shim APIs, which enables development of chaincodes using Java language.

Application developers interested in developing smart contracts (what we call chaincode) for Hyperledger Fabric should read the tutorial in TUTORIAL.md file and visit Chaincode for developers <https://hyperledger-fabric.readthedocs.io/en/latest/chaincode4ade.html>__.

Contributors or early adopters who need to be able to build and test recent Java chaincode shim, should reference FAQ.md file.

This project creates fabric-chaincode-protos and fabric-chaincode-shim jar files for developers consumption and the hyperledger/fabric-javaenv docker image to run Java chaincode.

The "fabric-chaincode-protos" folder contains the protobuf definition files used by Java shim to communicate with Fabric peer.

The "fabric-chaincode-shim" folder contains the java shim classes that define Java chaincode API and way to communicate with Fabric peer.

The "fabric-chaincode-docker" folder contains instructions to the build hyperledger/fabric-javaenv docker image.

The "fabric-chaincode-example-gradle" contains an example java chaincode gradle project that includes sample chaincode and basic gradle build instructions.
