+Tracer Example
+==============
+
+This example shows how to persist Camel trace event messages into a database using JPA.
+It can be run using Maven or Ant.
+
+You will need to compile this example first:
+ mvn compile
+
+For a background in BAM see
+ http://activemq.apache.org/camel/tracer.html
+
+To run the example with Maven, type
+ mvn camel:run
+
+To run the example with Ant
+ a. You need to have Hibernate Core, Entity Manager and HSQLDB installed.
+ They can be downloaded from the following locations
+ Hibernate Core 3.2.6 GA
+ http://www.hibernate.org
+ Hibernate Entity Manager 3.2.0.GA
+ http://prdownloads.sourceforge.net/hibernate/hibernate-entitymanager-3.2.0.GA.zip?download
+ HSQLDB
+ http://hsqldb.org/
+
+ b. Export / Set home directories for the above as follows
+ UNIX
+ export HIBERNATE_CORE_HOME=<path to Hibernate install directory>
+ export HIBERNATE_EM_HOME=<path to Hibernate EM install directory>
+ export HSQLDB_HOME=<path to HSQLDB install directory>
+ Windows
+ set HIBERNATE_CORE_HOME=<path to Hibernate install directory>
+ set HIBERNATE_EM_HOME=<path to Hibernate EM install directory>
+ set HSQLDB_HOME=<path to HSQLDB install directory>
+
+ c. To Run the example using Ant, type
+ ant
+
+In the HSQL Database Explorer type
+ select * from camel_messagetraced
+
+to see the trace events of the Exchanges. Notice how the Exchange correlates with
+fromNode/toNode so you exactly can see how a given Exchange was routed in Camel.
+
+
+Using the query:
+ select shortExchangeId, previousNode, toNode, body from camel_messagetraced order by id
+
+is a bit more easier to read as it uses the fields we are most interrested in to see how Exchanges
+was routed in Camel.
+
+In the console you can enter some words separated with space. Try to enter:
+ nice beer
+ beer whiskey
+ camel nice day
+
+This example will based on the input get some quotes from the input and select the best quote
+to return as response in the console.
+
+To stop the example hit ctrl + c
+
+To use log4j as the logging framework add this to the pom.xml:
+ <dependency>
+ <groupId>log4j</groupId>
+ <artifactId>log4j</artifactId>
+ </dependency>
+and log4j.properties is located in src/main/resources
+
+For the latest & greatest documentation on how to use this example please see
+ http://activemq.apache.org/camel/tracer-example.html
+
+If you hit any problems please let us know on the Camel Forums
+ http://activemq.apache.org/camel/discussion-forums.html
+
+Please help us make Apache Camel better - we appreciate any feedback you may
+have. Enjoy!
+

+The Camel riders!
