iBATIS问题(jar包)

Question

我启动tomcat的时候 如果不加ibatis-2.3.4.726.jar 就连接不上
加这个jar包的话 就报
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlMapClient' defined in ServletContext resource [/WEB-INF/applicationContext-ibatis.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.ibatis.SqlMapClientFactoryBean]: Constructor threw exception; nested exception is java.lang.UnsupportedClassVersionError: com/ibatis/sqlmap/engine/transaction/external/ExternalTransactionConfig (Unsupported major.minor version 49.0)

at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:425)是我jar包 加的不对么 还是其他的原因

Answer 1

检查下你项目用的jdk是你安装的jdk嘛？

Answer 2

Windows-->Preferences在弹出的窗口中选择java-->compiler在右上方Compile compliance level:把1.5改成1.4应该就行了吧

Answer 3

我没有用eclipse啊 其实是以前的一个项目 要按手顺导出来 但我照着手顺操作遇到了这些问题 很无奈啊 

Answer 4

你下的ibatis需要JDK1.5你用JDKK1.4是不支持的，你可以升级你的JDK版本或下载支持1.4的ibatis

Answer 5

是ibatis-2.3.4.726.jar 包 不支持JDK1.4么 
那相对应的支持JDK1.4的iBATIS jar包是什么啊 我没法改JDK版本 必须用1.4的

Answer 7

UnsupportedClassVersionError升级你jkd的版本，把jkd升级到5.0以上，是你jdk的版本过低造成的。

Answer 8

JDK要求的必须用这个啊 没法升级啊
ibatis-2.3.4.726.jar 原先不是这里的 是我后加的 
是不是可以用其他jar包 替换一下这个包 功能相同的

Answer 9

假如你是用的jdk1.4.2的话 ibatis的版本用ibatis2.3.0就可以 我试过 已经成功 ，网上说的jdk版本的问题，其实不是，而是ibatis的版本问题，兄弟换个ibatis2.3.0的jar包就可以了
