Ok, so I tried deploying the unmodified Whiteboard extended sample (version
7.2.14) from
https://github.com/ops4j/org.ops4j.pax.web/tree/web-7.2.14/samples/whiteboard-extended
<https://github.com/ops4j/org.ops4j.pax.web/tree/web-7.2.14/samples/whiteboard-extended>
in Karaf 4.2.8.
I made sure my jetty xml has the jettyConn1 connection:
<Call name="addConnector">
<Arg>
<New class="org.eclipse.jetty.server.ServerConnector">
<Arg name="server">
<Ref refid="Server" />
</Arg>
<Arg name="factories">
<Array
type="org.eclipse.jetty.server.ConnectionFactory">
<Item>
<New
class="org.eclipse.jetty.server.HttpConnectionFactory">
<Arg
name="config">
<Ref
refid="httpConfig" />
</Arg>
</New>
</Item>
</Array>
</Arg>
<Set name="host">
<Property name="jetty.host"
default="localhost" />
</Set>
<Set name="port">
<Property name="jetty.port"
default="8282" />
</Set>
<Set name="idleTimeout">
<Property name="http.timeout"
default="30000" />
</Set>
<Set name="name">jettyConn1</Set>
</New>
</Arg>
</Call>
I can see the servlets are deployed:
karaf@root()> http:list
ID │ Servlet │ Servlet-Name │ State │
Alias │ Url
───┼──────────────────────┼──────────────────────────────┼─────────────┼───────────────────────────┼─
309 │ WhiteboardServlet │ ServletModel-26 │ Deployed │
/whiteboard │ [/whiteboard/*]
309 │ WhiteboardServlet │ ServletModel-28 │ Deployed │
/whiteboard2 │ [/whiteboard2/*]
309 │ WhiteboardServlet │ ServletModel-30 │ Deployed │
/whiteboard3 │ [/whiteboard3/*]
309 │ WhiteboardServlet │ ServletModel-32 │ Deployed │
/whiteboard4 │ [/whiteboard4/*]
But Jetty is responding 404 to GET on http://localhost:8282/whiteboard
<http://localhost:8282/whiteboard> , same for all other ports.
I see this warning in the log file:
2020-03-10T10:12:07,497 | WARN | features-3-thread-1 | ContextHandler
| 245 - org.eclipse.jetty.util - 9.4.22.v20191022 | ContextHandler
[localhost, @jettyConn1] has a connector only entry e.g. "@connector" and one
or more host only entries.
The host entries will be ignored to match legacy behavior. To clear this
warning remove the host entries or update to use at least one host@connector
syntax entry that will match a host for an specific connector
What does this warning means?
Why is Jetty responding with a 404?
Best regards,
