SSL Configuration of the Camel 3.0.0 HTTP component in a blueprint route seems to be incomplete

[Gerald Kallas]

Dear community,

I'm using Karaf 4.2.7 with Camel 3.0.0. For calling an external HTTPS resource 
I need to configure the truststore for the Camel HTTP component. See my 
blueprint route below

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:camel="http://camel.apache.org/schema/blueprint";>
<!-- set JMS connection factory -->
<bean id="jmsConnectionFactory" 
class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616" />
<property name="userName" value="admin" />
<property name="password" value="xxxxx" />
</bean>
<!-- set truststore -->
<camel:sslContextParameters id="sslContextParameters">
<camel:keyManagers keyPassword="xxxxx">
<camel:keyStore 
resource="/home/ec2-user/casisp-runtime/apache-karaf-4.2.7/etc/truststore.jks" 
password="xxxxx" />
</camel:keyManagers>
</camel:sslContextParameters>
<camelContext id="isp.routes.system.deployment" 
xmlns="http://camel.apache.org/schema/blueprint";>
<route id="isp.routes.system.deployment">
<from uri="file:/tmp/in?include=.*\.xml&amp;moveFailed=error" />
<log message="isp.routes.system.deployment - Route started" />
<!-- set HTTP header values -->
<setHeader name="CamelHttpMethod">
<constant>GET</constant>
</setHeader>
<setHeader name="Content-Type">
<constant>application/json</constant>
</setHeader>
<setHeader name="Authorization">
<constant>Basic xxxxx</constant>
</setHeader>
<toD 
uri='https://ec2-3-124-33-3.eu-central-1.compute.amazonaws.com:8080/api/v2/data/integrationservice?filter={"deployDev":
 true}&amp;sslContextParameters=#sslContextParameters' />
<to uri="activemq:queue:IN" />
<log message="isp.routes.system.deployment.xml - Route finished" />
</route>
</camelContext>
</blueprint>

The truststore contains 1 self signed PEM cert from the destination.

Finally I'm still getting an error

javax.net.ssl.SSLHandshakeException: PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: unable to find 
valid certification path to requested target

Do I still miss something?

Is there any other way to configure a truststore globally for the HTTP 
component?

Many thanks in advance for any comments and hints.

Best
