Question

I am developing a GWT application.

And I would like to know if I am running over a Jboss instance or over a Jetty instance.

This is because if I am running over Jetty it means that I am running the dev mode and I need to redirect to MyModule.html?codeserver… but if I am running over Jboss I need to redirect to MyModule.html

But I can’t figure how can I know if I am running over Jetty or over Jboss.

Answer 1

You should not try to find out the webserver on which your application is running, in your application code. Instead you can have a discriminating parameter set in the context of your application with different values for different servers.

E.g.

For JBoss, the server.xml can contain a parameter in the context definition as follows:

<Context ...>
    ...
    <Parameter name="applicationStage" value="prod" />
    ...
</Context>

and for Jetty, the same context parameter would go into its jetty.xml but the value as “devo”.
