August 09, 2013 Posted by Sachin Handiekar , , , 5 comments

In this example we will see how to use an external property file in Fuse ESB / Apache Karaf.

Creating a configuration file

Create a config file named sample.cfg in FUSE_HOME/etc with the following content.

Spring Configuration


Blueprint 


Note : The default blueprint placeholder syntax (accessing the blueprint properties directly) is ${Key}. Hence, outside the scope of a camelContext element, the placeholder syntax you must use is ${Key}. Whereas, inside the scope of a camelContext element, the placeholder syntax you must use is {{Key}}.

Note: Please make sure you've got the Oracle Driver in your local/remote maven repository. If you don't have it please install with the following maven command -

mvn install:install-file -Dfile=ojdbc6.jar -DgroupId=com.oracle \
    -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar
