Re: Error with camel-example-etl

Hi

I can reproduce the error after the whole build.
After digging the code and check the change log, I found the Hadrain may copy past a wrong piece of code :( 

Here are my patch

That is generally a good idea to when some issue occur. To do a svn up
and do a full rebuild and try again.

Hadrian did some changes to camel-juel.

Have you rebuild all your code?

Oh, you need to compile the example first, like mvn compile.
Or using mvn install to install the jar.
mvn camel:run will not build the src for you :(

 Hi Charles,

The example can run by using mvn camel:run.
Did you run it with camel:run or deploy the bundle into OSGi
environment?
