# JDBC Package for Connected Device Configuration/Foundation Profile (JSR169)

Derby supports the JDBC API defined for the Connected Device Configuration/Foundation Profile, also known as JSR169. The features supported are a subset of the JDBC 3.0 specification. Support for JSR169 is limited to the embedded driver. Derby does not support using the Network Server under JSR169.

To obtain a connection under JSR169 specifications, use the `org.apache.derby.jdbc.EmbeddedSimpleDataSource` class. This class is identical in implementation to the `org.apache.derby.jdbc.EmbeddedDataSource` class. See the Java DB Developer's Guide for information on using the properties of the `org.apache.derby.jdbc.EmbeddedDataSource` class.

Some other features to note concerning the JSR169 implementation using Derby:

- Applications must get and set `DECIMAL` values using alternate JDBC `getXXX` and `setXXX` methods, such as `getString()` and `setString()`. Any alternate method that works against a DECIMAL type with JDBC 2.0 or 3.0 will work in JSR169.
- Java functions and procedures that use server-side JDBC parameters such as `CONTAINS SQL`, `READS SQL DATA` or `MODIFIES SQL DATA` are not supported in JSR169.
- The standard API used to obtain a connection (`jdbc:default:connection`) is not supported in JSR169. A runtime error may occur when the routine tries to obtain a connection using `jdbc:default:connection`.
- Diagnostic tables are not supported.
- Triggers are not supported.
- Encrypted databases are not supported.
- DriverManager is not supported. You cannot use DriverManager.getConnection() to obtain a connection.
