本文详细介绍了在使用JavaEE5.0开发时，遇到Tomcat启动时报错找不到javax.persistence.Table类的问题。通过查找原因发现，是因为缺少javaee-api-5.0-1.jar依赖包。文章最终提供了解决方案并附上了相关链接。

今天写了个解析javax.persistence.Table的方法

/**
	 * 通过实体的anno获得Mapping的数据库表名
	 * @param clazz 实体类
	 * @return
	 * @throws Exception
	 */
	public static String getTableName(Class<?> clazz) throws Exception {  
        if (clazz.isAnnotationPresent(Table.class)) {  
        	Table table = clazz.getAnnotation(Table.class);  
            return table.name();
        } else {  
            throw new Exception(clazz.getName() + " is not Entity Annotation.");  
        }  
    }

在启动tomcat的时候报错

找了一个晚上终于找到答案了。

原因是tomcat里面没有javaee-api-5.0-1.jar这个jar包，我用的是javaee 5.0。
