I added the following entry to web.xml: <env-entry> <env-entry-name>firstName</env-entry-name> <env-entry-value>Dave</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry> This worked OK. Then I wanted to override the value so I added the following to orion-web.xml: <env-entry-mapping name="firstName">Joe</env-entry-mapping> After doing this, Orion took it upon it's self to modify my <env-entry> by switching the order of value and type from "env-entry-name,env-entry-value,env-entry-type" (as specified in the servlet spec) to "env-entry-name,env-entry-type,env-entry-value". This in-turn cause a fatal error because I have validateXML turned on. All of this in addition to the fact the my overridden value was never actually made available to the jsp. Am i doing something wrong or is this a bug? Dave Ford
