How to add a SSL connector for apache karaf?

While searching for an answer to this question I stumbled upon http://blog.nanthrax.net/2013/02/multiple-http-connectors-in-apache-karaf/ and Jetty SSL configuration Apache karaf but this information is outdated. I found the new documentation at https://www.eclipse.org/jetty/documentation/current/configuring-connectors.html and the examples differ from proposed configurations. Apache Karaf 4.0.2 seems to use Jetty 9.

I already have a keystore at ${karaf.home}/etc/keystores/keystore.jks and would like just to add a second ssl connector at port 14000. How to do that?

Here's my org.ops4j.pax.web.cfg:

org.osgi.service.http.port=8181

org.osgi.service.http.port.secure=8443
org.osgi.service.http.secure.enabled=true
org.ops4j.pax.web.ssl.keystore=./etc/keystores/keystore.jks
org.ops4j.pax.web.ssl.password=password
org.ops4j.pax.web.ssl.keypassword=password

org.ops4j.pax.web.config.file=${karaf.home}/etc/jetty.xml

Here's my jetty.xml:

<Configure id="Server" class="org.eclipse.jetty.server.Server">
    <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.SslConnectionFactory"></New>
                        </Item>
                        <Item>
                            <New class="org.eclipse.jetty.server.HttpConnectionFactory"></New>
                        </Item>
                    </Array>
                </Arg>
                <Set name="host">
                    <Property name="jetty.host" default="0.0.0.0" />
                </Set>
                <Set name="port">
                    <Property name="jetty.port" default="14000" />
                </Set>
                <Set name="idleTimeout">
                    <Property name="http.timeout" default="30000" />
                </Set>
                <Set name="name">restConnector:14000</Set>
            </New>
        </Arg>
    </Call>
</Configure>

I had to set name like this to workaround an ArrayIndexOutOfBoundsException 1 in pax-web-jetty-4.2.2.jar at org.ops4j.pax.web.service.jetty.internal.ServerControllerImpl$Stopped.start(ServerControllerImpl.java:503):

String[] split = connector.getName().split(":");
if (httpSecurePort == Integer.valueOf(split[1])
        .intValue()
        && address.equalsIgnoreCase(split[0])) { ... }

Now the connector seems to start from what I see in the log:

But if I try to open https://localhost:14000/ in my browser I get ERR_CONNECTION_CLOSED and the following exception is thrown:

...
Caused by: javax.net.ssl.SSLHandshakeException: no cipher suites in common
        at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)[:1.8.0_60]

Do I miss something in the jetty configuration?

I recently had to face the same situation that I passed pretty easily. I created my own jks self-signed and then configured only Pax Web via cfg files.

  1. Create JKS

    keytool -genkeypair -keyalg RSA -validity 2048 \ -alias dontesta-karaf \ -dname "cn=karaf.dontesta.it, ou=R&D Labs, o=Antonio Musarra's Blog, C=IT, L=Rome, S=Italy" \ -keypass changeit -storepass changeit \ -keystore dontesta-karaf-server.jks \ -ext SAN=DNS:www.dontesta.it,DNS:services.dontesta.it

  2. Configure CFG Pax Web

    javax.servlet.context.tempdir = /Users/amusarra/Progetti/Karaf/runtime/apache-karaf-4.0.8/data/pax-web-jsp org.ops4j.pax.web.config.file = /Users/amusarra/Progetti/Karaf/runtime/apache-karaf-4.0.8/etc/jetty.xml org.osgi.service.http.port = 8181

    org.osgi.service.http.secure.enabled=true org.ops4j.pax.web.ssl.keystore=${karaf.etc}/keystore/dontesta-karaf-server.jks org.ops4j.pax.web.ssl.password=changeit org.ops4j.pax.web.ssl.keypassword=changeit

After hours of trying out different configurations and debugging with eclipse debugger plus log:set DEBUG in karaf I finally came to the right configuration. Here it is:

<Configure id="Server" class="org.eclipse.jetty.server.Server">
  <New id="sslContextFactory" class="org.eclipse.jetty.util.ssl.SslContextFactory">
    <Set name="KeyStorePath"><Property name="jetty.home" default="." />/etc/keystores/keystore.jks</Set>
    <Set name="KeyStorePassword">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
    <Set name="KeyManagerPassword">OBF:1u2u1wml1z7s1z7a1wnl1u2g</Set>
    <Set name="TrustStorePath"><Property name="jetty.home" default="." />/etc/keystores/keystore.jks</Set>
    <Set name="TrustStorePassword">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
  </New>
  <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.SslConnectionFactory">
                <Arg name="next">http/1.1</Arg>
                <Arg name="sslContextFactory"><Ref refid="sslContextFactory"/></Arg>
              </New>
            </Item>
            <Item>
              <New class="org.eclipse.jetty.server.HttpConnectionFactory"></New>
            </Item>
          </Array>
        </Arg>
        <Set name="host">
          <Property name="jetty.host" default="0.0.0.0" />
        </Set>
        <Set name="port">
          <Property name="jetty.port" default="14000" />
        </Set>
        <Set name="idleTimeout">
          <Property name="http.timeout" default="30000" />
        </Set>
        <Set name="name">restConnector:14000</Set>
      </New>
    </Arg>
  </Call>
</Configure>

The crucial points are:

  • Pick a connector name with a colon to workaround PAXWEB-907
  • An instance of SslContextFactory should be created with keystore properties and referenced in SslConnectionFactory
  • It is needed to declare both SslConnectionFactory and HttpConnectionFactory whereby it is important to declare them right in this order.
