説明

C-JDBC Driver for client side. This driver is a generic driver that is designed to replace any specific JDBC driver that could be used by a client. The client only has to know the node where the C-JDBC controller is running and the database he wants to access (the RDBMS could be PostgreSQL, Oracle, DB2, Sybase, MySQL or whatever, we only need the name of the database and the C-JDBC controller will be responsible for finding the RDBMs hosting this database).

The C-JDBC driver can be loaded from the client with: Class.forName("org.objectweb.cjdbc.driver.Driver");

The URL expected for the use with C-JDBC is: jdbc:cjdbc://host1:port1,host2:port2/database.

At least one host must be specified. If several hosts are given, one is picked up randomly from the list. If the currently selected controller fails, another one is automatically picked up from the list.

Default port number is 25322 if omitted.

Those 2 examples are equivalent:

 DriverManager.getConnection("jdbc:cjdbc://localhost:/tpcw");
 DriverManager.getConnection("jdbc:cjdbc://localhost:25322/tpcw");

Examples using 2 controllers for fault tolerance:

 DriverManager
     .getConnection("jdbc:cjdbc://cluster1.objectweb.org:25322,cluster2.objectweb.org:25322/tpcw");
 DriverManager
     .getConnection("jdbc:cjdbc://localhost:25322,remote.objectweb.org:25322/tpcw");
 DriverManager
     .getConnection("jdbc:cjdbc://smpnode.com:25322,smpnode.com:1098/tpcw");

This code has been inspired from the PostgreSQL JDBC driver by Peter T. Mount <peter@retep.org.uk>and the MM MySQL JDBC Drivers from Mark Matthews <mmatthew@worldserver.com>.

メソッド

synchronized boolean org.objectweb.cjdbc.driver.Driver.acceptsURL (  String  url  )  throws SQLException
 

Tests if the URL is understood by the driver. Calls the parseURL() method.

引数:
url the JDBC URL.
戻り値:
true if the URL is correct, otherwise an exception with extensive error message is thrown.
例外:
SQLException if the URL is incorrect an explicit error message is given.

java.sql.Connection org.objectweb.cjdbc.driver.Driver.connect (  String  url,
Properties  info
)  throws SQLException
 

Asks the C-JDBC controller if the requested database can be accessed with the provided user name and password. If the C-JDBC controller can't access the requested database, an SQLException is thrown, else a "fake" Connection is returned to the user so that he or she can create Statements.

引数:
url the URL of the C-JDBC controller to which to connect.
info a list of arbitrary string tag/value pairs as connection arguments (usually at least a "user" and "password").
戻り値:
a Connection object that represents a connection to the database through the C-JDBC Controller.
例外:
SQLException if an error occurs.

We cannot raise a SQLException as the driver manager tries to connect to all registered drivers. So if the CJDBC_URL_HEADER is not found we should probably pass... and return null Driver.java の 212 行で定義されています。

boolean org.objectweb.cjdbc.driver.Driver.jdbcCompliant (   ) 
 

Reports whether the driver is a genuine JDBC compliant driver. A driver may only report true here if it passes the JDBC compliance tests, otherwise it is required to return false. JDBC compliance requires full support for the JDBC API and full support for SQL 92 Entry Level. We cannot ensure that the underlying JDBC drivers will be JDBC compliant, so it is safer to return false.

戻り値:
always false
