Question
Hi,
I am a new user to Tomcat and am converting from Websphere server to a Tomcat 6.0 server running out of eclipse. The Websphere server has Environment variables in "java:comp/env/EnvironmentVariables". After looking at the context.xml documentation I had assumed that I could place them in the individual <Environment> tags. My application does a lookup using a Context.lookup("java:comp/env/EnvironmentVariables") method to find the Environment variables so when I startup Tomcat I get errors because it is looking at the "java:comp/env/EnvironmentVariables" for my Environment variables. Does anyone have suggestions on what I am doing wrong or am I completely on the wrong track? Thank in advance for any help you may give.
Thanks,
Marc Marshall

You should be able to code the <Environment> elements this way:
<Context>
...
<Environment name="EnvironmentVariables/email.abc.signup.subject"
value="Sign Up for the ABC Plan"
type="java.lang.String" override="false" />
...
</Context>

Is there something that I could add to my context.xml file to add the "EnvironmentVariables" to my directory tree? I am attempting to keep from modifying my code because it runs in Websphere in production and I am using Tomcat in my local environment. Thanks in advance for any help. Sorry next time I will post with a more meaningful subject line.
Thanks,
Marc Marshall

If I've interpreted the spec correctly, you should be looking for java:comp/env/email.abs.signup.subject; AFAICT, there's no "EnvironmentVariables" level in the directory tree defined in the spec.
Also, where is your context.xml file? Note that Tomcat copies the <Context> element to conf/Catalina/[host]/[appName].xml, which from that point on overrides the one in the webapp's META-INF/context.xml file. So if you modify the latter, it will be ignored until you redeploy the webapp or delete the copy.

P.S. In the future, use a subject line a bit more meaningful that "Question".

RE: Question
Posted by "Marshall, Marc" <Ma...@SUG.com>.
I am defining each of the Environment Variables in an <Environment> Tag inside of the context.xml like:
<Context>
...
<Environment name="email.abc.signup.subject" value="Sign Up for the ABC Plan"
type="java.lang.String" override="false" />
...
</Context>
I am getting an nullpoint exception when doing something with information returned from Context.lookup("java:comp/env/EnvironmentVariables") method here is the exact stack trace:

How are you defining the resource in Tomcat, exactly?
What is the full stacktrace of the error in the logs?
