XAConnectionBuilder (Java SE 26 & JDK 26)
Description: declaration: module: java.sql, package: javax.sql, interface: XAConnectionBuilder
Keywords: javax.sql.XAConnectionBuilder interface

# Interface XAConnectionBuilder

public interface XAConnectionBuilder
A builder created from a `XADataSource` object, used to establish a connection to the database that the `data source` object represents. The connection properties that were specified for the `data source` are used as the default values by the `XAConnectionBuilder`.

The following example illustrates the use of `XAConnectionBuilder` to create a `XAConnection`:

        XADataSource ds = new MyXADataSource();
        ShardingKey superShardingKey = ds.createShardingKeyBuilder()
                              .subkey("EASTERN_REGION", JDBCType.VARCHAR)
                              .build();
        ShardingKey shardingKey = ds.createShardingKeyBuilder()
                              .subkey("PITTSBURGH_BRANCH", JDBCType.VARCHAR)
                              .build();
        XAConnection con = ds.createXAConnectionBuilder()
                          .user("rafa")
                          .password("tennis")
                          .shardingKey(shardingKey)
                          .superShardingKey(superShardingKey)
                          .build();
