# 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
<pre>sudo apt-get install maven</pre>
```
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
<pre>mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcChecker" -Dexec.args="-host localhost"</pre>
## How to run jdbcTaosDemo
## Run jdbcDemo using mvn plugin
run command:
<pre> mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.jdbcTaosdemo.JdbcTaosdemo"</pre>
```
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo"
```
and run with your customed args
<pre>mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.jdbcTaosdemo.JdbcTaosdemo" -Dexec.args="-host localhost"</pre>
```
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
<pre>
```
mvn clean package assembly:single
</pre>
```
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]
```
To run it, go to ``examples/JDBC/JDBCDemo/target`` and execute
<pre>java -jar jdbcChecker-SNAPSHOT-jar-with-dependencies.jar -host localhost</pre>
