Class JDBCConfigurationLoader

java.lang.Object
  org.osesb.configuration.JDBCConfigurationLoader

public class JDBCConfigurationLoader
extends java.lang.Object

This Class is a helper for loading JDBCConfiguration(s). First, a JDBCConfiguration can specify either a <databaseConnection> or a <dataSource> content model. Second, JDBCConfiguration(s) are typically embedded within other configurations (see TableSetConfiguration). Further, the jdbc-configuration can be explicitly embedded or referenced as an external file by the configFile and contentModelTagName attributes of a <jdbc-configuration> content model.

Since:

Version .9

Method Detail

loadJDBCConfiguration

public static JDBCConfiguration loadJDBCConfiguration(org.w3c.dom.Element jdbcContentModelElement)
                                               throws java.lang.Exception

Loads the JDBCConfiguration from a contentModel Element.

Example JDBCConfiguration:

<jdbc-configuration>
          <databaseConnection>
              <!-- DB2 Type 4 Driver -->
              <driverClass>com.ibm.db2.jcc.DB2Driver</driverClass>
              <databaseURL>jdbc:db2://localhost:50000/SAMPLE</databaseURL>
              <userName>db2admin</userName>
              <password>db2admin</password>
              <debugFlag>true</debugFlag>
               <!-- dbPing interval in seconds. -->
               <!-- Used in conjunction with the 'useConnectionManager' attribute of the 'databaseConnection' tag. -->
               <!-- Used by a DriverConnectionManager to periodically test a connection. -->
               <!-- Default is no dbPing. -->
               <dbPingIntervalSeconds></dbPingIntervalSeconds>
          </databaseConnection>
      </jdbc-configuration>
 

Or

<jdbc-configuration
          configFile="config/test/some-config-file.xml"
          xpathExpression="//jdbc-configuration/databaseConnection">
      </jdbc-configuration>
 

Parameters:

jdbcContentModelElement - The Element that contains the JDBCConfiguration.

Returns:

a JDBCConfiguration or null if a ConfigurationConstants.JDBCCONFIG_CONTENTMODEL is not present.

Throws:

java.lang.Exception - if the JDBCConfiguration exists, but could not be loaded due to an error.
