Question

struts+hibernate整合开发，tomcat就出问题 ，谁帮忙看看！！！

本人用struts单独开发一个项目没有任何问题，所有的文件配置全正确。但是一旦加入hibernate开发支持，再重新部署tomcat就出问题。重启tomcat可以正常运行程序，但是千万不能重新部署，部署就出错。tomcat也重装过很多次，都没用。也建了很多项目试过，都证明了这点。struts与hibernate放到一起就出错，我怀疑是两者相冲突所致。错误描述：

我还有有一个朋友也出现同样的错误，也证明了只要两者放到一起就出错。错误时一样的。这个问题困扰了好多天了一直没有解决。希望高人指点。hibernate包是MyEclipse自带的3.2版本 struts2包只加入了6个常用的jar包不知道是否有人也遇到过这种问题。求解，这种问题有工作经验的应该也许会碰到过。小弟经验尚且不足，希望指教！

Answer 1

只加struts2的的6个JAR包,这样是可以的。把你的web.xml 以及struts2.xml 发来我看看。看有没有让spring 进行托管。还有。你的strut2 是用myeclipse 自带的struts2.1 么？
