Available as of Camel 2.7
This is an additional component for Camel to run DNS queries, using DNSJava. The component is a thin layer on top of DNSJava.
The component offers the following operations:
- ip, to resolve a domain by its ip
- lookup, to lookup information about the domain
- dig, to run DNS queries
|Requires SUN JVM|
The DNSJava library requires running on the SUN JVM.
If you use Apache ServiceMix or Apache Karaf, you'll need to adjust the etc/jre.properties file, to add sun.net.spi.nameservice to the list of Java platform packages exported. The server will need restarting before this change takes effect.
Maven users will need to add the following dependency to their pom.xml for this component:
