Embedded Tomcat
Hi
I'm currently working on integrating embedded tomcat in the OPS4j Pax Web
OSGi container as alternativ underlying web container. Right now I'm stuck
on a certain point that is kind of hard to understand so I'm sure I'm doing
something "awfully" wrong :)
So here is what I'm struggling with.
Using Tomcat 8 embedded core
While the context is started I eventually end up at [1]
This is the point I don't get cause I'd expect Servlets to be started at
[2], but obviously the Servlets are already started at [1]. Therefore the
ServletContainerInitializers are never called [3].
Now my question, what am I doing wrong, as all servlets are registered as
children.
I'm very well aware that these questions might not really make a lot of
sense, therefore you'll find the current implementation at [4].
regards, Achim

Hi Mark,
thanks for the pointer I think I've found the reason.
Could it be that the initialization of the servlets changed from 7 to 8 :)
I used to load the servlet in the initialization phase. So that's the part
I need to alter.
Need to move that part to the loadOnStartup method call.
just in case anyone is interested, I've linked the source in question below
[1].

Put a break point on StandardWrapper.startInternal() and see what the
call stack is at that point.

Might be interested in the way Pax Web works then ;)
still, does anyone know why the children, containing also the Servlets, are
started before the ServletContainerInitializers and/or
what am I doing wrong. Most likely my assumption is wrong but I couldn't
spot which one.
I somehow fear that while registering the Wrapper I'm doing something
wrong.

yes we tried to go that way with whiteboard registration also (jetty is
shipped by default in eclipse also with that)
but that was way to hard to control and to really configure the way we want
so we decided to make tomcat a full osgi package itself.

Re: Embedded Tomcat
Posted by Achim Nierbeck <bc...@googlemail.com>.
Hi Johan,
thanks for the pointer. To me it looks like it does have a different scope.
Pax Web has been one of the first OSGi HttpService providers with
additional support for Web Application Bundles (std. war with OSGi Manifest)
This has been achieved so far very successfully with Jetty. Now we try to
add additional Containers like Tomcat and Undertow.
As for this Pax Web needs to be the one in control over registering
Servlets etc. by either HttpService registration, Whiteboard registration
or by using the bundle-extender approach.
You could regard this to be a mediation layer between the OSGi Service
Registry and the underlying web-container.
regards, Achim

Re: Embedded Tomcat
Posted by Johan Compagner <jc...@servoy.com>.

https://github.com/Servoy/servoy-eclipse-tomcat
thats also a osgi enabled tomcat (but the full tomcat) we use that one
right in eclipse, where other plugins just contribute filters and servlets
