# Java Platform Support

LibreOffice supports the Java platform for running applications and components based on the JavaBeans architecture.

For LibreOffice to support the Java platform, you must install the Java 2 Runtime Environment software. When you installed LibreOffice, you automatically received the option to install these files if they were not yet installed. You can also install these files now if required.

The Java platform support needs to be activated under LibreOffice to run Java applications.

- Enable Java platform support by choosing LibreOffice - Preferences Tools - Options - LibreOffice - Advanced.

Before you can use a JDBC driver, you need to add its class path. Choose LibreOffice - Preferences Tools - Options - LibreOffice - Advanced, and click the Class Path button. After you add the path information, restart LibreOffice.

Your modifications at the LibreOffice - Preferences Tools - Options - LibreOffice - Advanced tab page will be used even if the Java Virtual Machine (JVM) has been started already. After any modifications to the ClassPath you must restart LibreOffice. The same is true for modifications under LibreOffice - Preferences Tools - Options - Internet - Proxy. Only the boxes "HTTP Proxy" and "FTP Proxy" and their ports do not require a restart—they will be evaluated when you click OK.
