Subject Connection object was null when configured directly
Date Tue, 10 Jun 2003 02:30:36 GMT
Hi

does anybody know what's wrong here. When I startup torque, the connection 
object seems to be null. I get a correspondig exception. That only happens if 
I configure Torque during runtime. If I use the Torque.properties-file, 
everything works fine.

java.lang.NullPointerException: Connection object was null. This could be due 
to a misconfiguration of the DataSourceFactory. Check the logs and 
Torque.properties to better determine the cause.

I configured torque during runtime with the following code:
try {
	// If Torque has not been initialized yet, do so
	if(!Torque.isInit()) {
		BaseConfiguration torqueConfig = new BaseConfiguration();

		String connectionString = "jdbc:" + databaseType + "://" + databaseHost +
		":" + databasePort + "/project";

		torqueConfig.addProperty("log4j.rootCategory", "DEBUG, default");

		torqueConfig.addProperty("log4j.rootCategory", "WARNINGS, default");

		torqueConfig.addProperty("log4j.appender.default",
			"org.apache.log4j.FileAppender");

		torqueConfig.addProperty("log4j.appender.default.file", "logs/torque.log");

		torqueConfig.addProperty("log4j.appender.default.layout",
			"org.apache.log4j.SimpleLayout");

		torqueConfig.addProperty("torque.database.default", "project");

		if(databaseType.equals("postgresql")) {
			torqueConfig.addProperty("torque.database.default.adapter", "postgresql");
			torqueConfig.addProperty("torque.dsfactory.default.connection.driver",
				"org.postgresql.Driver");
		}
		else
			throw new DatabaseNotSupportedException(databaseType);

		System.out.println(connectionString);
		
		torqueConfig.addProperty(
		"torque.dsfactory.default.pool.defaultMaxConnections", "10");

		torqueConfig.addProperty(
		"torque.dsfactory.default.pool.maxExpiryTime", "3600");

		torqueConfig.addProperty(
		"torque.dsfactory.default.pool.connectionWaitTimeout", "10");
		
		torqueConfig.addProperty("torque.dsfactory.default.factory",
		"org.apache.torque.dsfactory.TorqueDataSourceFactory");

		torqueConfig.addProperty(
		"torque.dsfactory.default.connection.url", connectionString);
				
		torqueConfig.addProperty("torque.dsfactory.default.connection.user",
		"postgres");

		torqueConfig.addProperty("torque.dsfactory.default.connection.password",
		"");
		
		Torque.init(torqueConfig);
		assert(Torque.isInit());
	}
}


If I initialize Torque with the Torque.properties-file everything works fine:
log4j.category.org.apache.torque = DEBUG, org.apache.torque
log4j.appender.org.apache.torque = org.apache.log4j.FileAppender
log4j.appender.org.apache.torque.file = 
${torque.applicationRoot}/logs/torque.log
log4j.appender.org.apache.torque.layout = org.apache.log4j.PatternLayout
log4j.appender.org.apache.torque.layout.conversionPattern = %d [%t] %-5p %c - 
%m%n
log4j.appender.org.apache.torque.append = false

log4j.rootCategory = DEBUG, default
log4j.appender.default = org.apache.log4j.FileAppender
log4j.appender.default.file = ./torque.log
log4j.appender.default.layout = org.apache.log4j.SimpleLayout

torque.database.project.adapter=postgresql
torque.dsfactory.project.factory=org.apache.torque.dsfactory.TorqueDataSourceFactory
torque.dsfactory.project.pool.defaultMaxConnections=10
torque.dsfactory.project.pool.maxExpiryTime=3600
torque.dsfactory.project.pool.connectionWaitTimeout=10
torque.dsfactory.project.connection.driver = org.postgresql.Driver
torque.dsfactory.project.connection.url = 
jdbc:postgresql://localhost:5432/project
torque.dsfactory.project.connection.user = postgres
torque.dsfactory.project.connection.password =


Any ideas? Thank you for any help.
Malte.
