## Config

Run this command in your terminal to save the JDBC URL as variable:


<Tabs defaultValue="bash">
<TabItem value="bash" label="Bash">

export TDENGINE_JDBC_URL="<jdbcURL>"
```
</TabItem>
<TabItem value="cmd" label="CMD">

```bash

<!-- exclude -->
:::note
Replace  <jdbcURL\> with real JDBC URL, it will seems like: `jdbc:TAOS-RS://example.com?usessl=true&token=xxxx`.

To obtain the value of JDBC URL, please log in [TDengine Cloud](https://cloud.tdengine.com) and click "Connector" and then select "Java".

## Connect

Code bellow get JDBC URL from environment variables first and then create a `Connection` object, witch is a standard JDBC Connection object.

```java
{{#include docs/examples/java/src/main/java/com/taos/example/ConnectCloudExample.java:connect}}
```

<!---The client connection is then established. For how to write data and query data, please refer to [Insert Data](https://docs.tdengine.com/cloud/develop/insert-data#connector-examples) and [Query Data](https://docs.tdengine.com/cloud/develop/query-data/#connector-examples).--->
