Cannot create WebApplication context

[eliasbalasis]

Greetings,

I have created a sample spring-dm powered web application, which currently does nothing but displaying some static content (servicing a couple of static HTML pages).

After enabling spring-dm osgi context support in web.xml (as described in docs section 9.7 with OsgiBundleXmlWebApplicationContext etc)

I unexpectedly started getting the following error

... some more exception info (less important) follow, about bundle failed to start and bundle stopping etc. but could not fit in post ...

No idea where this came from.
"bundle context should be set before refreshing the application context"?
I was hoping that the web extender is responsible for this, which by the way is installed and active (version 1.2.1, compatible, not initially existed, manually added as recommended in docs) in the dm-server 2.0.0 instance I tried to deploy the sample webapp.

Any ideas?

[eliasbalasis]

Correction, web extender is NOT running.

I missed this output when I first installed web extender

It is obvious that without web extender my webapp will never get a chance to properly start.

Any ideas why web extender is not starting?

I was expecting that Tomcat deployer is by default installed and active. Exception log above shows otherwise.

Still, service of class org.apache.catalina.Service was not found running in DM-Server instance. Makes sense.

Perhaps I have to provide a related fragment. But again I was expecting such a fragment already existing.

Or perhaps not. Hmmm, from another point of view it is not necessary, depends on application container requirements what to start and what not to.
Suspecting there is a reason tomcat is not started by default.
Investigating..........

[eliasbalasis]

Web Extender still fails to start although the Tomcat starter bundle catalina.start.osgi is properly deployed and started
(after changing its configuration .xml to resolve HTTP port conflict on default port 8080)

Any ideas?

[frederic.conrotte]

same problem here with Spring DM 1.1.2 as well

It seems the issue was fixed:
http://jira.springframework.org/browse/OSGI-595

but apparently it's still occuring, at least with 1.1.2 version.

Isn't Jetty supposed to work better ?

[frederic.conrotte]

After 2 painful hours of digging, I just repackaged catalina.start.osgi-1.0.0.jar changing default port to be 8090 but then Catalina still starts on port 8080 !?

[eliasbalasis]

Well, this JIRA issue suggests the start order is a quick and dirty solution.
So far so good. I will try this......

Still, catalina.osgi.start bundle (after repackaging it changing conf/default-server.xml) is not starting (did not observe related output on log file, as on JIRA posted issue)

In another article on this forum I read (I will post once found again) it is recommended to deploy a fragment of "catalina" bundles providing some additional tomcat xml files (context.xml, web.xml etc.)

I will post both the related article and the solution if it works for me.

Perhaps a look or even modification at catalina.osgi.start source code...........

On the other hand, Jetty could be a working alternative.
Providing Web Extender configuration with Jetty deployer instead of the default Tomcat should work provided that Jetty can be properly started.
Good idea, will try that too......

[frederic.conrotte]

Ok, I got it working with Spring DM 1.2.1 and Jetty

here is the list of dependencies

But I failed to change the default 8080 port so i had to ensure it was free at first

Guys, not sure if you're using the same setup but the first post indicates dmServer is used.
As for Spring DM and the web support have you tried the web samples?
