BOE.war redeployed, java.lang.RuntimeException: Could not find framework 解决办法

We have installed BOBJ 4.0 and everything was working 100%. Then we followed the
Windows AD Single Sign-on config in the Admin Guide, and on page 257 it says that you have to redeploy the BOE.war. After doing this the BOE application doesn't work anymore. We could get to the Tomcat main page (http://server:8080),
and I could see the list of deployed applications from here, but when you try to access the BOE apps (http://server:8080/BOE or
BOE/CMC), then we get a URL error with this error:

java.lang.RuntimeException: Could not find framework

I have find another solutions that works in our environment (your solution works as well)

In our case we didn't stop tomcat before deploying webapps with wdeploy tool, so I think that it was the cause of the problem, so to solve this, we followed the following steps:

stop apache and tomcat

undeployall

deployall

start apache and tomcat

hope this helps
