Hi
Actually, i don't do something complicate. I exactly follow blog
http://piotrnowicki.com/2011/03/using-servlets-3-0-servletcontainerinitializer
so my implementation just is the following:
import javax.servlet.*;
import java.util.*;
public class BundleServletContainerInitializer implements
ServletContainerInitializer {
public void onStartup(Set<Class<?>> c, ServletContext cx) {
System.out.println("--- CONTAINER INITIALIZER! ---");
}
}then package this class as jar BundleServletContainerInit.jar, and put it into
that web application WEB-INF/lib directory.
I also have one question in my mind, why do i need this? As you can see, it
doesn't do anything useful, even BundleServletContainerInitializer
implements ServletContainerInitializer.

Hi,
The problem that you received shows that BundleServletContainerInitializer does
not implement javax.servlet.ServletContainerInitializer. [1]
If this is not the case then please provide an example.
servlet-api.jar is provided as a bundle with Gemini Web package -
javax.servlet-3.0.0.v201103241009

Hi
I refer this blog
http://piotrnowicki.com/2011/03/using-servlets-3-0-servletcontainerinitializer
to write a new java file named BundleServletContainerInitializer which
implement interface ServletContainerInitializer, it override function
onStartup(Set<Class<?>> c, ServletContext ctx) , i don't do any complicate
implementation but print some logs, and build it into a separated Jar, then put
it into WEB-INF/lib/ directory of web application bundle. at last, i run felix
again, i got the following error:

Hi,
Gemini Web will initialize ServletContainerInitializer placed in
WEB-INF/lib/*.jar or placed in a bundle that is required by web app bundle i.e
import-packages or require-bundle.
Or you can use JarScannerCustomizer - here [1] you can find an example.
You can use one of these three methods depending on the scenario.

Violeta

Hi Violeta
Thanks for your quickly reply. Yes, i already download felix and Gemini web
bundles, then start felix with
"java -jar bin/felix.jar", all Gemini web bundles start successfully.
Let's firstly describe what i am done, then describe what problem i met, I
have several bundles to provide web service, just like hosttracker module from
opendaylight, please refer
https://git.opendaylight.org/gerrit/gitweb?p=controller.git;a=tree;f=opendaylight/northbound/hosttracker;hb=eee61ea351b6179d2862dce6875bdc25dd0fb272,
it has a web.xml to describe this web application's attribute, such as servlet
class, please refer hosttracker's web.xml
https://git.opendaylight.org/gerrit/gitweb?p=controller.git;a=tree;f=opendaylight/northbound/hosttracker/src/main/resources/WEB-INF;h=b42ae8116d116e38e6cf44eaffda6daeeba3b97c;hb=eee61ea351b6179d2862dce6875bdc25dd0fb272
Now, coming to my problem,
after start gemini web, when web application bundled get start, gemini web will
found it is web application, it will try to allocate one context container for
it, this is my understanding, if it is wrong, please correct me,
my error log is
can't find JAR for some web application URL ServletContainerInitializer
so because this error, gemini web mark that web application unavailable.
Then i follow this article
http://stackoverflow.com/questions/10776599/servletcontainerinitializer-vs-servletcontextlistener
to custom my servletcontainerinitializer, but still it doesn't work,
also i read tomcat source code, there is some code section to check whether the
servletcontainerinitializer existed?
but technically, the ServletContainerInitializer is not a listener �C it is an
initializer and it’s executed before
any servlet context will even be ready. You can use this initializer to
do some programatic servlet/filters/listeners addition,
So, is there any configuration option to make gemini web not to check it.

Hi,
Just download felix [1], then extract its archive and put all 34 Gemini Web
bundles in the "bundle" directory.
Then start felix with "java -jar bin/felix.jar".
That's all.
