Since Apache Camel 2.7, the Apache Camel requires at least JDK 1.6 (the recommended version is JDK 1.6.0_18) and also supports JDK 1.7.
Since Apache Camel 2.10, you require Maven 3.0.2 or later to build the source distribution of Apache Camel.
Since Apache Camel 2.7, Apache Camel has switched from Apache Commons Logging to the Simple Logging Facade for Java
(slf4j). If your application code uses log4j logging, you must now
include a dependency on the slf4j-log4j12 artifact. For example, if you use the
Maven build system, you would add the following Maven dependency to your POM file:
<project ...> <properties> <slf4j-version>1.6.1</slf4j-version> ... </properties> ... <dependencies> ... <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j-version}</version> </dependency> ... </dependencies> ... </project>
Where the slf4j version used by Apache Camel 2.8.0. is 1.6.1.
