How can I determine which application server I'm running in?

[mumbly]

Is there a generic, programmatic method for determining which app server (JBoss, WebSphere, Weblogic) I'm running in without passing such information in from the outside? If not a generic method, is there a good, safe way of doing so in the specific case of any of the above listed servers?

Thanks.

You could define a resource in your web.xml | ejb-jar.xml.
The resource could be assigned a value in the specific app server config file (jboss-web.xml, weblogic.xml,...).

Context initial = new InitialContext();
String appServer = (String)initial.lookup("java:comp/env/AppServer");
