In my tomcat deployed app I use the element in META-INF/context.xml to override the environment value in web.xml. This will be copied to the conf/engine-name/host-name/mywebappname.xml on the first deployment. The administrator can then amend the file to provide the real value he wants. In JBoss I cannot get this type of process to work. I have read a number of forums and jira issues referring to using context.xml and I have moved the file to WEB-INF. I have added additional xml to the context.xml file to make sure it is being parsed but the environment variable is not overriding the value in web.xml. Here is my file; I have tried true and false for the override. My questions are, will JBoss allow the web.xml env element (such as) <env-entry> A Test variable <env-entry-name>TestVariable</env-entry-name> <env-entry-type>java.lang.String</env-entry-type> <env-entry-value>TestValue</env-entry-value> </env-entry> to be overridden in the context.xml as per tomcat. secondly how can I get the context.xml to be externalised from the war file so it is not overwritten upon subsequent deploys of the war file.
