ConnectionPool

• java.lang.Object

Fields Summary
private String	dsn The data source name of the data source to use for the actual database connections. When configuring this connection pool in your JNDI repository, you should specify a value for this property.
private PrintWriter	logWriter The required log writer.
private int	loginTimeout The required login timeout.

Constructors Summary

Methods Summary
public java.lang.String	getDsn() The data source name of the data source this pool will use to create its actual connections. return the data source name return dsn;
public java.io.PrintWriter	getLogWriter() return the log writer throws java.sql.SQLException never actually thrown return logWriter;
public int	getLoginTimeout() return the login timeout throws java.sql.SQLException never actually thrown return loginTimeout;
public javax.sql.PooledConnection	getPooledConnection() Provides an application data source with a reference to a pooled connection. The pooled connection represents the physical connection to the database. Because this library is an abstraction for the sake of statement pooling, our physical connection is itself an abstraction. The job of the physical connection is to provide the application data source with a logical connection. return a pooled database connection throws java.sql.SQLException a connection error occurred return getPooledConnection(null, null);
public javax.sql.PooledConnection	getPooledConnection(java.lang.String uid, java.lang.String pw) Provides an application data surce with a reference to a pooled connection based on the specified authentication credentials. param uid the user ID to use in making the connection param pw the password to use in making the connection return the pooled connection throws java.sql.SQLException a connection error occurred if( loginTimeout > 0 ) { ConnectionAttempt att = new ConnectionAttempt(dsn, uid, pw); long start = System.currentTimeMillis(); long to = (long)(loginTimeout * 1000); synchronized( att ) { while( (System.currentTimeMillis() - start) < to ) { try { att.wait(to); } catch( InterruptedException e ) { } if( att.connection != null ) { return att.connection; } else if( att.exception != null ) { throw att.exception; } else { to = to - (System.currentTimeMillis() - start); } } throw new SQLException("Connection timed out."); } } else { return new PhysicalConnection(dsn, uid, pw); }
public void	setDsn(java.lang.String dsn) Sets the name of the data source to be used for generating connections. param dsn the name of the data source this.dsn = dsn;
public void	setLogWriter(java.io.PrintWriter out) Assigns a print writer for logging. param out the new print writer throws java.sql.SQLException never thrown logWriter = out;
public void	setLoginTimeout(int sec) Sets a new login timeout for this pool. param sec the login timeout in seconds throws java.sql.SQLException never thrown loginTimeout = sec;
