顶一下
[解决办法]
freemarker.log.JDK14LoggerFactory$JDK14Logger error
你用的jdk是1.4？
调到1.6看看
[解决办法]
是不是jdk或者是包的问题？
[解决办法]
struts2的标准jdk好像是jdk5.0

[解决办法]
把JDK调成1.5试试
[解决办法]
刚才查了一下，在JDK1.4也可以运行，这个你参考一下吧

[解决办法]
jdk改为1.5以上的版本看看
[解决办法]
MyEclipse有自带的jdk,需要配置一下
[解决办法]
楼主设置一下eclipse的compile jdk 选择你自己安装的1.6
右键工程，选择Properties --> 找到java compiler 修改 Compiler Compliance level,指定编译时使用的JDK 6.0
