Answer 1

看不明白，楼主能否在详细点，不过部署的时候有一点要注意，你的jdk必须是你安装目录(bea)下的那个jdk,仔细检查下吧

Answer 2

我的资源里有本 weblogic 教程，楼主可以去看看

Answer 3

我的JDK是用的BEA自带那个 ~~~  
我用JPA做一个小项目每次部署的时候就出现这两个错误。大体意思好像是找不到sessionManagement这个东西~~~

Answer 4

java.lang.NoClassDefFoundError: oracle/toplink/essentials/tools/sessionmanagement/SessionManager 少了toplink的jar包，去下载一个。
