The level of functionality is determined by the Fabric version in use and channel capabilities.\n\nAll Docker images, chaincode libraries and tools are tested using amd64 (x86-64) only.\n\n## Chaincode builder\n\nThe default Fabric chaincode builder creates a Docker container to run deployed smart contracts. Java chaincode Docker containers are built using the `hyperledger/fabric-javaenv` Docker image, tagged with the same major and minor version as the Fabric peer version. For example, Fabric v2.5 creates Java chaincode containers using the `hyperledger/fabric-javaenv:2.5` Docker image. Fabric v3 continues to use the v2.5 Java chaincode image.\n\nA different chaincode Docker image can be specified using the `CORE_CHAINCODE_JAVA_RUNTIME` environment variable on the Fabric peer. For example, `CORE_CHAINCODE_JAVA_RUNTIME=example/customJavaRuntime:latest`.\n\nWith Fabric v2 and later, an alternative chaincode builder can be configured on the Fabric peer. In this case the configured chaincode builder controls how chaincode is launched. See the [Fabric documentation](https://hyperledger-fabric.readthedocs.io/en/release-2.5/cc_launcher.html) for further details.\n\n## Chaincode packaging\n\nWhen using the `hyperledger/fabric-javaenv` Java chaincode Docker images, deployed chaincode is built as follows:\n\n- If both Gradle and Maven files are present, Gradle is used.\n- Gradle build files can be either Groovy or Kotlin.\n- If Gradle or Maven wrappers are present, they will be used instead of the preinstalled Gradle or Maven versions.\n\nRemember that when using the wrappers, code will be downloaded from the Internet. Keep this in mind for any installation with limited network access.\n\nAlternatively, it is recommended to package prebuilt JAR files, including the smart contract and all dependencies. In this case, no Internet access is required when deploying Java chaincode.\n" }, { "path": "CONTRIBUTING.md", "content": "# Contributing to fabric-chaincode-java\n\nWe welcome contributions to the [Hyperledger Fabric](https://hyperledger-fabric.readthedocs.io) Project. There's always plenty to do!\n\nIf you have any questions about the project or how to contribute, you can find us in the [fabric-contracts-api](https://discordapp.com/channels/905194001349627914/943090527920877598) channel on [Discord](https://discord.lfdecentralizedtrust.org/).\n\nHere are a few guidelines to help you contribute successfully...\n\n## Issues\n\nAll issues are tracked in the issues tab in GitHub. If you find a bug which we don't already know about, you can help us by creating a new issue describing the problem. Please include as much detail as possible to help us track down the cause.If you want to begin contributing code, looking through our open issues is a good way to start. Try looking for recent issues with detailed descriptions first, or ask us on Discord if you're unsure which issue to choose.\n\n## Enhancements\n\nMake sure you have the support of the Hyperledger Fabric community before investing a lot of effort in project enhancements. Please look up the [Fabric RFC](https://github.com/hyperledger/fabric-rfcs) process for large changes.\n\n## Pull Requests\n\nWe use our own forks and [Github Flow](https://docs.github.com/en/get-started/using-github/github-flow) to deliver changes to the code. Follow these steps to deliver your first pull request:\n\n1. [Fork the repository](https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project) and create a new branch from `main`.\n2. If you've added code that should be tested, add tests!\n3. If you've added any new features or made breaking changes, update the documentation.\n4. Ensure all the tests pass.\n5. Include the JIRA issue number, a descriptive message, and the [Developer Certificate of Origin (DCO) sign-off](https://github.com/dcoapp/app#how-it-works) on all commit messages.\n6. [Issue a pull request](https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project#making-a-pull-request)!\n7. [GitHub Actions](https://github.com/hyperledger/fabric-chaincode-java/actions) builds must succeed before the pull request can be reviewed and merged.\n\n## Coding Style\n\nPlease to try to be consistent with the rest of the code and conform to checkstyle rules where they are provided. [Spotless](https://github.com/diffplug/spotless) is used to enforce code formatting. You can run `./gradlew spotlessApply` to apply the mandated code formatting to the codebase before submitting changes to avoid failing the build with formatting violations.\n\n## Code of Conduct Guidelines \n\nSee our [Code of Conduct Guidelines](../blob/main/CODE_OF_CONDUCT.md).\n\n## Maintainers \n\nShould you have any questions or concerns, please reach out to one of the project's [Maintainers](../blob/main/MAINTAINERS.md).\n\n\n## How to work with the Codebase\n\nSome useful gradle commands to help with building.

Please see the tutorials in the [documentation](https://hyperledger-fabric.readthedocs.io/en/latest/tutorials.html)\n\n\n- **fabric-contract-example-gradle** - Contains an example Java contract built using gradle\n- **fabric-contract-example-maven** - Contains an example Java contract built using maven\n- **fabric-contract-example-gradle-kotlin** - Contains an example Kotlin contract build using gradle (Kotlin gradle files)\n- **fabric-chaincode-example-sacc** - Contains an example java chaincode gradle project that includes sample chaincode and basic gradle build instructions.\n- **fabric-chaincode-example-sbe** - Contains an example java chaincode gradle project that includes state based endorsement\n\n## 'dev' main branch builds\n\nThese 'dev' drivers are built from the main branch only, and have a version format including the date for example `2.3.1.dev.20210303`.\nThey are published to Artifactory. These can be accessed via the repository at\n```\n maven {\n url \"https://hyperledger.jfrog.io/hyperledger/fabric-maven\"\n }\n```\n\nThey can be accessed in a build file like this\n\n```\ndependencies {\n compile group: 'org.hyperledger.fabric-chaincode-java', name: 'fabric-chaincode-shim', version: '2.3.1.dev.+'\n }\n```\n\n\n## Building and testing\n\nMake sure you have the following prereqs installed:\n\n- [Docker](https://www.docker.com/get-docker)\n- [Docker Compose](https://docs.docker.com/compose/install/)\n- [JDK 11](https://adoptium.net/)\n\n> **Note:** Java can be installed using [sdkman](https://sdkman.io/).\n\nClone the repository if you haven't already.\n\n```\ngit clone https://github.com/hyperledger/fabric-chaincode-java.git\n```\n\nBuild java shim jars (proto and shim jars) and install them to local maven repository.\n\n```\ncd fabric-chaincode-java\n./gradlew clean build install\n```\n\n> **Note:** `./gradlew clean build classes` can be used instead to reduce the binaries that are built. This should be sufficient for using the local repository.\n\nBuild javaenv docker image, to have it locally.\n\n```\n./gradlew buildImage\n```\n\n## Compatibility\n\nFor details on what Java runtime and versions of Hyperledger Fabric can be used please see the [compatibility document](COMPATIBILITY.md).\n\n---\n\n[![Creative Commons License](https://i.creativecommons.org/l/by/4.0/88x31.png)](http://creativecommons.org/licenses/by/4.0/) \nThis work is licensed under a [Creative Commons Attribution 4.0 International License](http://creativecommons.org/licenses/by/4.0/)\n" }, { "path": "RELEASING.md", "content": "# Releasing\n\nThe following artifacts are created as a result of releasing Fabric Chaincode Java:\n\n- `fabric-javaenv` Docker images:\n - [Docker Hub](https://hub.docker.com/r/hyperledger/fabric-javaenv)\n - [GitHub Packages](https://github.com/orgs/hyperledger/packages/container/package/fabric-javaenv)\n- `fabric-chaincode-shim` Java libraries:\n - [Maven Central](https://central.sonatype.com/artifact/org.hyperledger.fabric-chaincode-java/fabric-chaincode-shim)\n - [GitHub Packages](https://github.com/hyperledger/fabric-chaincode-java/packages/50049)\n\n## Before releasing\n\nThe following tasks are required before releasing:\n\n- Ensure the version number in `build.gradle` is the required release version.\n- Check the last branch build passed since exactly this repository state will be released.\n\n## Create release\n\nCreating a GitHub release on the [releases page](https://github.com/hyperledger/fabric-chaincode-java/releases) will trigger the build to publish the new release.\n\nWhen drafting the release, create a new tag for the new version (with a `v` prefix).

If your /bin/sh is\n# noncompliant, but you have some other compliant shell such as ksh or\n# bash, then to run this script, type that shell name before the whole\n# command line, like:\n#\n# ksh Gradle\n#\n# Busybox and similar reduced shells will NOT work, because this script\n# requires all of these POSIX shell features:\n# * functions;\n# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,\n# «${var#prefix}», «${var%suffix}», and «$( cmd )»;\n# * compound commands having a testable exit status, especially «case»;\n# * various built-in commands including «command», «set», and «ulimit».\n#\n# Important for patching:\n#\n# (2) This script targets any POSIX shell, so it avoids extensions provided\n# by Bash, Ksh, etc; in particular arrays are avoided.\n#\n# The \"traditional\" practice of packing multiple parameters into a\n# space-separated string is a well documented source of bugs and security\n# problems, so this is (mostly) avoided, by progressively accumulating\n# options in \"$@\", and eventually passing that to Java.\n#\n# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,\n# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;\n# see the in-line comments for details.\n#\n# There are tweaks for specific operating systems such as AIX, CygWin,\n# Darwin, MinGW, and NonStop.\n#\n# (3) This script is generated from the Groovy template\n# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt\n# within the Gradle project.\n#\n# You can find Gradle at https://github.com/gradle/gradle/.\n#\n##############################################################################\n\n# Attempt to set APP_HOME\n\n# Resolve links: $0 may be a link\napp_path=$0\n\n# Need this for daisy-chained symlinks.\nwhile\n APP_HOME=${app_path%\"${app_path##*/}\"} # leaves a trailing /; empty if no leading path\n [ -h \"$app_path\" ]\ndo\n ls=$( ls -ld \"$app_path\" )\n link=${ls#*' -> '}\n case $link in #(\n /*) app_path=$link ;; #(\n *) app_path=$APP_HOME$link ;;\n esac\ndone\n\n# This is normally unused\n# shellcheck disable=SC2034\nAPP_BASE_NAME=${0##*/}\n# Discard cd standard output in case $CDPATH is set (https://github.com/gradle/gradle/issues/25036)\nAPP_HOME=$( cd \"${APP_HOME:-./}\" > /dev/null && pwd -P ) || exit\n\n# Use the maximum available, or set MAX_FD != -1 to use that value.\nMAX_FD=maximum\n\nwarn () {\n echo \"$*\"\n} >&2\n\ndie () {\n echo\n echo \"$*\"\n echo\n exit 1\n} >&2\n\n# OS specific support (must be 'true' or 'false').\ncygwin=false\nmsys=false\ndarwin=false\nnonstop=false\ncase \"$( uname )\" in #(\n CYGWIN* ) cygwin=true ;; #(\n Darwin* ) darwin=true ;; #(\n MSYS* | MINGW* ) msys=true ;; #(\n NONSTOP* ) nonstop=true ;;\nesac\n\nCLASSPATH=$APP_HOME/gradle/wrapper/gradle-wrapper.jar\n\n\n# Determine the Java command to use to start the JVM.\nif [ -n \"$JAVA_HOME\" ] ; then\n if [ -x \"$JAVA_HOME/jre/sh/java\" ] ; then\n # IBM's JDK on AIX uses strange locations for the executables\n JAVACMD=$JAVA_HOME/jre/sh/java\n else\n JAVACMD=$JAVA_HOME/bin/java\n fi\n if [ ! -x \"$JAVACMD\" ] ; then\n die \"ERROR: JAVA_HOME is set to an invalid directory: $JAVA_HOME\n\nPlease set the JAVA_HOME variable in your environment to match the\nlocation of your Java installation.\"\n fi\nelse\n JAVACMD=java\n if ! command -v java >/dev/null 2>&1\n then\n die \"ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.\n\nPlease set the JAVA_HOME variable in your environment to match the\nlocation of your Java installation.\"\n fi\nfi\n\n# Increase the maximum file descriptors if we can.\nif ! \"$cygwin\" && ! \"$darwin\" && ! \"$nonstop\" ; then\n case $MAX_FD in #(\n max*)\n # In POSIX sh, ulimit -H is undefined.

\n      MAX_INBOUND_MESSAGE_SIZE=104857600\n      CHAINCODE_METRICS_ENABLED=false\n      TP_CORE_POOL_SIZE=5\n      TP_MAX_POOL_SIZE=5\n      TP_QUEUE_SIZE=5000\n
\n\n

\n To override the defaults, a config.props Java properties file must be included in the default, unnamed, package on your contract code's classpath, which will then be loaded when the chaincode starts.\n Setting the metrics enabled flag to true will turn on default metrics logging. The TP_ values establish the core thread pool size, max thread poolsize, and the number of of tasks that will wait.\n

\n\n\n

Open Telemetry

\n

\n To use Open Telemetry, set the following properties:\n

\n 
\n      CHAINCODE_METRICS_ENABLED=true\n      CHAINCODE_METRICS_PROVIDER=org.hyperledger.fabric.metrics.impl.OpenTelemetryMetricsProvider\n
\n

\n Additionally, you can set properties after the OpenTelemetry specification.
\n Example:\n

\n 
\n      OTEL_EXPORTER_OTLP_ENDPOINT=otelcollector:4317\n      OTEL_EXPORTER_OTLP_INSECURE=true\n
\n\n\n

\n If you are building your chaincode using Gradle or Maven, create a config.props file in the src/main/resources directory and include the settings you want to override.\n
