# Step 1: Download driver and apply to the Pentaho Server

To connect to a database, including the Pentaho Repository database, you will need to download and copy a JDBC driver to the appropriate places for the Pentaho Server as well as on the web application server.

**Note:** Due to licensing restrictions, Pentaho cannot redistribute some third-party database drivers. You must download and install the file yourself.

1. Download a JDBC Driver JAR from your database vendor or a third-party driver developer.

   The [JDBC drivers reference](/install/10.2-install/jdbc-drivers-reference.md) has a list of supported drivers.
2. Copy the JDBC driver JAR you just downloaded to the `pentaho/server/pentaho-server/tomcat/lib` folder.
3. Copy the [`hsqldb-2.3.2.jar`](https://sourceforge.net/projects/hsqldb/files/hsqldb/hsqldb_2_3/) file to `pentaho-server/tomcat/lib` if you want to retain the sample provided by Pentaho.
