Hi,
I'm trying to use Turbine for the first time, so please excuse me if the
question seems obvious.
I've installed Turbine and Velocity and have both of their jar files in
tomcat/common/lib . Tomcat reports
that Turbine is initialized on startup. The following code:
import org.apache.turbine.services.TurbineServices;
import org.apache.turbine.util.TurbineException;
import org.apache.turbine.util.db.adapter.DB;
import org.apache.turbine.util.db.map.DatabaseMap;
.....
try {
DBConnection dbCon = TurbineDB.getConnection();
}catch(TurbineException te) {
System.out.println("TurbineException: " + e.getMessage());
e.printStackTrace();
}
results in the following error in the Tomcat console:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/stratum/configuration/Configuration
at
org.apache.turbine.services.db.TurbineDB.getPoolBroker(TurbineDB.java:340)
at
org.apache.turbine.services.db.TurbineDB.getConnection(TurbineDB.java:199)
at com.egps.factories.test.main(test.java:30)
This message is not coming from the catch() statment.
Please note that I'm using an example from a book called 'MySQL and JSP Web
Applications' and
the instructions for installing Turbine are probably outdated. I do not find
any reference to
'org/apache/stratum/configuration/Configuration' in either of the .jar files
I downloaded from the
Turbine site. I downloaded and installed version 2.2-b1. The entry in the
TurbineResources.properties
file follows:
