困惑了N天了.Appfuse的NoSuchTableException: user_role

按照:Raible大作(http://raibledesigns.com/wiki/Wiki.jsp?page=RunningOnOracle)布置Appfuse于Oracle上,在网上也查了许多资料,可是运行ant-setup时还是出现如下错误:
db-load:
[dbunit] Executing operation: CLEAN_INSERT
[dbunit] on file: E:\appfuse-springmvc-1.9.4-src\appfuse\metadata
\sql\sample-data.xml
[dbunit] with format: xml

BUILD FAILED
E:\appfuse-springmvc-1.9.4-src\appfuse\build.xml:689: org.dbunit.dataset.NoSuchTableException: user_role

注意我也参照了陈海青的"Appfuse，Running On Oracle时出现NoSuchTableException错误的解决.",使用了oracle的整个数据库系统跟踪功能,但也看不出来错在那里.
