Java Spring Blaze DS-ANTLR异常
我有一个简单的JavaSpring服务器,它使用hibernate访问数据库。但是,当尝试对数据库表执行查询时,flex数据服务向导testOperation函数会返回此错误消息Java Spring Blaze DS-ANTLR异常,java,apache-flex,spring,blazeds,Java,Apache Flex,Spring,Blazeds,我有一个简单的JavaSpring服务器,它使用hibernate访问数据库。但是,当尝试对数据库表执行查询时,flex数据服务向导testOperation函数会返回此错误消息 InvocationTargetException:There was an error while invoking the operation. Check your server settings and try invoking the operation again. Reason: Server err
InvocationTargetException:There was an error while invoking the operation. Check your server settings and try invoking the operation again.
Reason: Server error java.lang.NoClassDefFoundError : antlr/ANTLRException null
现在antlr jar位于服务器的类路径和lib文件夹中,所以我看不出这是怎么回事。是否有人知道为什么会发生此错误。这是控制台输出,也是有帮助的。我创建了另一个名为foo的类,它使用相同的hibernate模板将bar对象保存到数据库中,这非常有效。仅当尝试在用户数据库上执行操作时

如果您有这个问题,那么新的ANTLR jar就会出现问题,请清理您的类路径并导入ANTLR.2.7.6,看看这是否解决了问题。为我工作
