Class JdbcDataSource

java.lang.Object
  org.h2.message.TraceObject
      org.h2.jdbcx.JdbcDataSource

All Implemented Interfaces:

java.io.Serializable, java.sql.Wrapper, javax.naming.Referenceable, javax.sql.CommonDataSource, javax.sql.ConnectionPoolDataSource, javax.sql.DataSource, javax.sql.XADataSource

public class JdbcDataSource
extends TraceObject
implements javax.sql.XADataSource, javax.sql.DataSource, javax.sql.ConnectionPoolDataSource, java.io.Serializable, javax.naming.Referenceable

A data source for H2 database connections. It is a factory for XAConnection and Connection objects. This class is usually registered in a JNDI naming service. To create a data source object and register it with a JNDI service, use the following code:

 import org.h2.jdbcx.JdbcDataSource;
 import javax.naming.Context;
 import javax.naming.InitialContext;
 JdbcDataSource ds = new JdbcDataSource();
 ds.setURL("jdbc:h2:˜/test");
 ds.setUser("sa");
 ds.setPassword("sa");
 Context ctx = new InitialContext();
 ctx.bind("jdbc/dsName", ds);
 

To use a data source that is already registered, use the following code:

 import java.sql.Connection;
 import javax.sql.DataSource;
 import javax.naming.Context;
 import javax.naming.InitialContext;
 Context ctx = new InitialContext();
 DataSource ds = (DataSource) ctx.lookup("jdbc/dsName");
 Connection conn = ds.getConnection();
 

In this example the user name and password are serialized as well; this may be a security problem in some cases.
