I’m trying to deploy an application to Apache Felix. It was a gwt application but I’ve been simplifying the problem until just a hello world html file so my problem is to deploy any kind of web application in a war file. I’ve also tried to deploy the generated wars in Apache Karaf and they worked without any problems (once you install feature war).
So, right now I have this:
blaxter@duffman:~/devel/webapp $ tree
.
├── pom.xml
├── src
└── main
├── resources
└── webapp
├── foobar.html
└── WEB-INF
└── web.xml
The pom.xml is pretty straightforward, the interesting part is related with felix plugin, but for this war without any compiled code it doesn’t matter…

The pax plugin is also there because I’ve tried to run the application with that, but I got the same result. The web.xml is an empty one:
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<welcome-file-list>
<welcome-file>foobar.html</welcome-file>
</welcome-file-list>
</web-app>
Once you execute mvn package to generate the war file, if I deploy it in Apache Felix I get no errors, the bundle state is active but I only get 404 errors trying to access /sample paths. I’ve tried put both sample and /sample as context path values. The same behaviour happens running mvn pax:run. If I deploy the war in Apache karaf, it works so I’d assume I’m doing something really wrong with felix.

The bundles that were doing the work were OPS4J-* ones, but the ones running jetty were the org.apache.felix.http.*. Once I removed org.apache.felix.http.* bundles everything started to work.
