Java chaincode cheatsheet

Attempting to figure out how to do stuff with Java chaincode on Fabric. Don't try this at home!

The following is based on Java chaincode generated using generator-fabric running in a fabric-devenv Vagrant environment.

v1.4???

CORE_PEER_ADDRESS=0.0.0.0:7051 \
CORE_PEER_LOCALMSPID=Org1MSP \
CORE_PEER_MSPCONFIGPATH=/home/vagrant/test-network/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp \
peer chaincode install -l java -n mycc -v v1 -p <path_to_chaincode>

CORE_PEER_ADDRESS=0.0.0.0:7051 \
CORE_PEER_LOCALMSPID=Org1MSP \
CORE_PEER_MSPCONFIGPATH=/home/vagrant/test-network/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp \
peer chaincode instantiate -o 0.0.0.0:7050 -C mychannel -n mycc  -v v1 -c '{"Args":[]}' -P 'OR ("Org1MSP.member")'

CORE_PEER_ADDRESS=0.0.0.0:7051 \
CORE_PEER_LOCALMSPID=Org1MSP \
CORE_PEER_MSPCONFIGPATH=/home/vagrant/test-network/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp \
peer chaincode invoke -n mycc -c '{"Args":["CreateAsset", "1"]}' -C mychannel -o 127.0.0.1:7050

v2???

docker exec -it cli bash
peer lifecycle chaincode package pc0.tar.gz --path /opt/gopath/src/github.com/contracts/java-contract/ --lang java --label pc_0
peer lifecycle chaincode install pc0.tar.gz
export CC_PACKAGE_ID=$(peer lifecycle chaincode queryinstalled 2>&1 | awk -F "[, ]+" '/Label: /{print $3}') && echo $CC_PACKAGE_ID
peer lifecycle chaincode approveformyorg --channelID mychannel --name pc_0 --version 0.0.3 --package-id $CC_PACKAGE_ID --sequence 1 --waitForEvent
peer lifecycle chaincode commit -o orderer.example.com:7050 --channelID mychannel --name pc_0 --version 0.0.3 --sequence 1 --waitForEvent
peer chaincode invoke -o orderer.example.com:7050 --channelID mychannel --name pc_0 -c '{"Args":["arg1","arg2"]}'
