Deployment of Dubbo microservices for seata.

Hi team,
I am trying deployment of Dubbo microservices for seata using following steps:

**1. Startup Seata Server**
`docker run --name seata-server -p 8091:8091 -p 7091:7091 seataio/seata-server:1.5.0`

**logs_startup_seata_server:** [seata-sample.txt](https://github.com/seata/seata-samples/files/9948718/seata-sample.txt)

**UI interface for seata-server:** 

**2. Startup Zookeeper**
`docker run --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 -d zookeeper` this command is running successfully for me.

**3.Execute SQL under seata-samples\dubbo\src\main\resources\sql**
I am stuck on how to execute microservices under above mentioned path step, I also tried to run these .java files (AccountService.java, BusinessService.java, OrderService.java, StockService.java) directly by using `javac filename.java` but not able to start them and failed with this error
**Error_logs:** [error.txt](https://github.com/seata/seata-samples/files/9948772/error.txt)

Could you please have a look and provide your feedback regarding the same.

Start by reading seata-samples/dubbo/src/main/resources/sql and the entry points AccountService.java, BusinessService.java, OrderService.java, and StockService.java, then review the attached error log. Determine how this sample is intended to start its services instead of compiling individual files with javac. Done means the SQL step is completed and the Dubbo microservices start successfully with Seata and ZooKeeper.
