Date Sun, 28 Sep 2003 06:13:07 GMT

hi,




  the following properties r set in torque.properties file-



log4j.category.org.apache.torque = ALL, 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



## Using commons-dbcp 
torque.dsfactory.bookstore.factory=org.apache.torque.dsfactory.SharedPoolDataSourceFactory
torque.dsfactory.bookstore.pool.defaultMaxActive=10
torque.dsfactory.bookstore.pool.testOnBorrow=true
torque.dsfactory.bookstore.pool.validationQuery=SELECT 1
torque.dsfactory.bookstore.connection.driver = org.gjt.mm.mysql.Driver
torque.dsfactory.bookstore.connection.url = jdbc:mysql:///bookstore
torque.dsfactory.bookstore.connection.user = 
torque.dsfactory.bookstore.connection.password = 


and build.properties has the following database settings


torque.database.createUrl = jdbc:mysql:///mysql
torque.database.buildUrl = jdbc:mysql:///bookstore
torque.database.url = jdbc:mysql:///bookstore
torque.database.driver = org.gjt.mm.mysql.Driver
torque.database.user = 
torque.database.password =
torque.database.host =


torque.targetPackage = de.stephanwiesner      
torque.database.default=bookstore
torque.database.bookstore.adapter=mysql
torque.project = bookstore
torque.sameJavaName = false


rgds,


vidya



 


 



Hi,
I had this error, in the very beginning, I couldn't remember
the exact reason, but it steps into a wrong/ missing property files
(Torque.property, schema.xml) , or an incompatible version of common
logging or related jars. may be I can help you if I see the property
files.

regards,
Alvin
