带有CAR和控制台的WSO2 EI611 Kafka连接器入站端点错误

Question

https://docs.wso2.com/display/ESBCONNECTORS/Configuring+Kafka_2.12-0.11.0.0+Operations https://docs.wso2.com/display/ESBCONNECTORS/Configuring+Kafka+Inbound+Operations https://docs.wso2.com/display/ESBCONNECTORS/Kafka_2.12-0.11.0.0+Connector+and+Inbound+Endpoint

There's no directory structure like the one mentioned in one of above documentation links:

To configure the Kafka inbound endpoint, copy the following client libraries from the /lib directory to the /repository/components/lib directory.

I configured Kafka InboundEndpoint with EI611 on management console and received this error in logs :

org.apache.kafka.common.KafkaException: Exception while loading Zookeeper JAAS login context 'Client'...... Caused by: java.lang.SecurityException: java.io.IOException: C:\\WSO2EI~1.1\\bin..\\repository\\conf\\identity\\jaas.conf (No such file or directory)

Alternatively, I developed a Inbound endpoint from tooling and deploy the CAR file, I get the following error :

I hope the above documentation is written based on the WSO2 ESB. If you are using EI please copy your all relevant 3rd party libraries to /lib. Please add the jaas.conf[1] file to the directory (/repository/conf/identity/)
