Grouper Users - Open Discussion List

[Monica Crawford <>]

Hi Gary,

Thanks so much.  I can run the below w/in the with Weblogic 9.2 and 
JBoss 4.0.2 containers.  I followed the upgrades to accommodate a 2.4 
servlet spec and 2.0 jsp spec. and made the grouper-el rtexpvalue I also 
noticed that it worked in weblogic when I compiled the files against the 
servlet-api.jar (2.4 jar file).

FYI, the shipped grouper-ui, it works as is under a 2.3/1/1 servlet 
spec/jsp spec for JBoss 4.0.2 but not for Weblogic 9.X. BEA says the 
issue w/ struts-el and WL 9.X is solvable only if you upgrade to 2.4.

Monica
