org.frankframework.jta.narayana.PoolingDataSourceJDBCAccess

All Implemented Interfaces:

com.arjuna.ats.arjuna.objectstore.jdbc.JDBCAccess

public class PoolingDataSourceJDBCAccess
extends Object
implements com.arjuna.ats.arjuna.objectstore.jdbc.JDBCAccess

Alternative to DataSourceJDBCAccess that adds connection pooling, instead of doing a JNDI lookup each time a connection is called. getConnection() will be called for every transaction, pooling will drastically improve performance.

Method Details

Specified by:

getConnection in interface com.arjuna.ats.arjuna.objectstore.jdbc.JDBCAccess

Throws:

SQLException

initialise

public void initialise(StringTokenizer stringTokenizer)

Since we've already verified the connection in NarayanaConfigurationBean we can almost be certain this won't fail. In case such a thing does happen, throw a fatal exception because we may absolutely not continue initializing the application.

Specified by:

initialise in interface com.arjuna.ats.arjuna.objectstore.jdbc.JDBCAccess
