hibernate+struts一个非常奇怪的出错,想了半天也不知什么原因

Question

查询不要用事务。。而且你的事务放的位置也不对，应该放在catch里。。

Answer 1

查询可以有事务！
估计是你的WEB应用没有获得SESSION或Hibernate的配置问题。
下次把抛的异常也贴出来。

你eclipse发布的web?，如果是在eclipse里选中你的工程点右键+ properties + myeclipse + myeclipse-web 出现在选项卡，选择deployment  单选选择第2个。复选选2 3.最后点OK就行了
呵呵。不知道行不行。可以试试。以前经常出错。老是说找不包

Answer 5

java.io.FileNotFoundException: log4j.properties (系统找不到指定的文件。)
在你的classPath下面要放入这个文件。log4j.properties

Answer 6

antlr-2.7.6rc1.jar可能需要复制到web/WEB-INF/lib文件夹下。

Answer 7

hibernate3里面查询少写sql语句或者hql为好充分用好Criteria
