public class InformixDataSource
extends org.apache.avalon.framework.logger.AbstractLoggable
implements DataSourceComponent

The Informix implementation for DataSources in Excalibur. This uses the com.informix.jdbcx.IfxConnectionPoolDataSource object. It uses the following format for configuration (italics mark information you change):

   <informix>
     <pool-controller init="5" min="5" max="10"/>
     <dbname>dbname</dbname>
     <servername>servername</servername>
     <host port="2000">host</host>
     <user>user</user>
     <password>user</password>
   <informix>
 
Informix doesn't like the JdbcDataSource Component, so we gave it it's own. Do not use this datasource if you are planning on using your J2EE server's connection pooling. You must have Informix's JDBC 2.2 or higher jar file, as well as the extensions jar file (ifxjdbc.jar and ifxjdbcx.jar). Also, this DataSource requires the Avalon Cadastre package because it uses the MemoryContext.
