我在ECLIPSE裡面對org.jbpm.db.DbTests.java用JUNIT進行DEBUG時，輸出資訊如下：

它提示無法找到JDBC Driver class not found: oracle.jdbc.driver.OracleDriver

我已經在C:\jbpm.3\lib\目錄下新建了oracle目錄，並且已經把classes12.jar檔案放到裡面了。不過我不清楚JbpmSessionFactory.java是如何找到這些jar檔案的。

我的c:\jbpm.3\src\org\jbpm\目錄下的jbpm.properties檔案內容如下：

jbpm.scheduler.service.factory=org.jbpm.scheduler.impl.SchedulerServiceImpl
jbpm.task.instance.class=org.jbpm.taskmgmt.exe.TaskInstance


# uncomment the next line to use the file system instead of the database for
# storing files related to a process definition
# jbpm.files.dir=c:/jbpm.data

# resource path to a properties file that will overwrite all the hibernate
# properties. For database specific builds in db project there is a different
# hibernate.properties file on the classpath for each database. You could change
# the default database for any testing runs by uncommenting the next line and
# adding a hibernate.properties file in the basedir.
jbpm.hibernate.properties=hibernate.properties
jbpm.hibernate.cfg.xml=c:/jbpm.3/src/resources/hibernate.cfg.xml

hibernate.dialect=net.sf.hibernate.dialect.Oracle9Dialect
hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
hibernate.connection.url=jdbc:oracle:thin:@127.0.0.1:1521:ORCL
hibernate.connection.username=JBPM
hibernate.connection.password=JBPM
jbpm.create.tables=only-if-not-present
jbpm.create.tables.log=false
jbpm.file.mgr=database
jbpm.id.generator=default
hibernate.show_sql=true
hibernate.query.substitutions=true 1, false 0


請高手幫幫我吧，我急死了！
