Glassfish Informix JDBC
I recently had a need to get an Informix database connection going on Glassfish . This is documented but what I found was not quite enough to get me going. I was using the JDBC driver from IBM . After the driver is installed, there are six jar files in the lib directory. Given that Informix is one of our primary databases, we use this driver with a variety of Java-based development tools. Typically this involves making the ifxjdbc.jar file available on the CLASSPATH and you're good to go. In order to create an Informix JDBC Connection Pool in Glassfish, I found that I needed to put both the ifxjdbc.jar and the ifxjdbcx.jar files in Glassfish lib directory. I used javax.sql.DataSource as the Resource Type and entered com.informix.jdbcx.IfxDataSource as the Datasource Classname . The additional settings properties I entered are pictured below. HTH, Carl
