-# How to Run the JDBC Demo Code On A Linux OS
+# How to Run the JDBC Demo Code On Linux OS
TDengine's JDBC demo project is organized in a Maven way so that users can easily compile, package and run the project. If you don't have Maven on your server, you may install it using
-sudo apt-get install maven
+```
+sudo apt-get install maven
+```
## Install TDengine Client
Make sure you have already installed a tdengine client on your current develop environment.
Download the tdengine package on our website: ``https://www.taosdata.com/cn/all-downloads/`` and install the client.
-## How to run jdbcChecker
-mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcChecker" -Dexec.args="-host localhost"
-
-## How to run jdbcTaosDemo
+## Run jdbcDemo using mvn plugin
run command:
- mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.jdbcTaosdemo.JdbcTaosdemo"
+```
+mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo"
+```
+
and run with your customed args
-mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.jdbcTaosdemo.JdbcTaosdemo" -Dexec.args="-host localhost"
+```
+mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo" -Dexec.args="-host [HOSTNAME]"
+```
## Compile the Demo Code and Run It
+To compile taos-jdbcdriver, go to the source directory ``TDengine/src/connector/jdbc`` and execute
+```
+mvn clean package -Dmaven.test.skip=true
+```
To compile the demo project, go to the source directory ``TDengine/tests/examples/JDBC/JDBCDemo`` and execute
-
-
+```
mvn clean package assembly:single
-
+```
-The ``pom.xml`` is configured to package all the dependencies into one executable jar file.
+To run JDBCDemo.jar, go to ``TDengine/tests/examples/JDBC/JDBCDemo`` and execute
+```
+java -Djava.ext.dirs=../../../../src/connector/jdbc/target:$JAVA_HOME/jre/lib/ext -jar target/JDBCDemo-SNAPSHOT-jar-with-dependencies.jar -host [HOSTNAME]
