Christoph (et all) Thanks much.. OK.. I did get further.. I had a few errors..
1. My SQLMapConfig.xml file was not there.. as when I use POJOs I usually name it differently and then use code to look it up. I did see the reference to "If the file is located in another location, you will need to configure the configurationUri option on the MyBatisComponent component." on the http://camel.apache.org/mybatis.html .. so for now.. I simply named it back.. 2. My velocity template was not properly referencing the returned collection. Fixed that and poof... So.. my route of .. from("direct:start") // start from camel itself .. no input queue .to("mybatis:selectMyList?statementType=SelectList") // select list of bulletin board messages. .log("Tapped message body is ${body}") .to("velocity:myVelocityTemplate.vm") // run velocity against input message .to("file://target/subfolder") // write the output of the velocity to a file. .to("mock:result"); now works as desired.. Last hurdle .. get this into the servlet output stream.. My travels thus far have taught me a bit more as to how to read and interpret http://camel.apache.org/servlet.html I am inching closer to my "ah ha" moment.. Kind Regards, Michael L.
