有没有人用过torque?我碰到问题了。

运行例子中的Bookstore时出现异常，如下：

java.lang.NullPointerException: There was no DataSourceFactory configured for the connection bookstore
at org.apache.torque.Torque.getConnection(Torque.java:938)
at org.apache.torque.util.Transaction.beginOptional(Transaction.java:113)
at org.apache.torque.util.Transaction.begin(Transaction.java:97)
at com.kazmier.om.BasePublisher.save(BasePublisher.java:420)
at com.kazmier.om.BasePublisher.save(BasePublisher.java:401)
at com.kazmier.Bookstore.main(Bookstore.java:26)

我的Torque.properties是这样的：

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.default=bookstore
torque.database.bookstore.driver = oracle.jdbc.driver.OracleDriver
torque.database.bookstore.url = jdbc:oracle:thin:@192.168.8.3:1521:dr128gh
torque.database.bookstore.username = test
torque.database.bookstore.password = test

帮你顶一下

OR-Mapping用的。跟JDO的功能差不多

[bjzhanghao]

谢谢！

[airlulu]

已经解决，加上了这段（从它的默认运行时配置文件抄的，EXAMPLE上面没有！）
torque.dsfactory.bookstore.factory=org.apache.torque.dsfactory.TorqueDataSourceFactory
torque.dsfactory.bookstore.pool.defaultMaxConnections=10
torque.dsfactory.bookstore.pool.maxExpiryTime=3600
torque.dsfactory.bookstore.pool.connectionWaitTimeout=10
torque.dsfactory.bookstore.connection.driver = oracle.jdbc.driver.OracleDriver
torque.dsfactory.bookstore.connection.url = jdbc:oracle:thin:@192.168.8.3:1521:dr128gh
torque.dsfactory.bookstore.connection.user = test
torque.dsfactory.bookstore.connection.password = test

torque是做什么用的？也是数据库驱动吗

[airlulu]

最后在这里推荐一下torque,
功能就是根据配置文件来自动生成数据库模式和相应的JAVA类，达到JDO的效果，又能够对IDE支持（因为不是好像JDO那样用类增强器来实现）。而且生成的JAVA类的扩展性也比较好～～～。

明显驱动配置不对吗。
例子说明都有的。
