Error during channel creation about blockchain-application-using-fabric-java-sdk HOT 1 CLOSED

Hi....
I am facing the following issue while creating the channel. Please help me in this.
Thank you..

I created my own project with the help of this project
Steps I followed while running:

* Go to network folder and issue the following command

* cryptogen generate --config=./crypto-config.yaml

* configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./config/genesis.block

* configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./config/channel.tx -channelID lennahc

* configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./config/Org1MSPanchors.tx                                                                       channelID $CHANNEL_NAME -asOrg Org1MSP

* configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./config/Org2MSPanchors.tx channelID $CHANNEL_NAME -asOrg Org2MSP

* Updated docker-compose.yml

* ./build.sh

* cd ../java

* mvn install

* cd target

* cp blockchain-java-sdk-0.0.1-SNAPSHOT-jar-with-dependencies.jar blockchain-client.jar

* cp blockchain-client.jar ../../network_resources

* cd ../../network_resources

* java -cp blockchain-client.jar org.app.network.CreateChannel
  When I run this command I got the following

log4j:WARN Please initialize the log4j system properly.
