TypeConverter not being loaded?

I suppose I'm confused about how to load my TypeConverter.  I have a Spring
web-app running in tomcat (tried glassfish too), have an annotated class,
and have placed a TypeConverter in several locations, including
/META-INF/services/org/apache/camel, /WEB-INF, and /WEB-INF/classes. 
However, when Camel loads debug shows only the standard TypeConverters being
loaded.  Any thoughts on what I could be doing wrong?  I would think I
should at least see my class being loaded/referenced?

Thanks for any insight!
-J

-----------------------------------------
1) The TypeConverter file has just one line which is the package of my
class, com.me.converters

2) My converter declaration:
@Converter
public final class MyBeanConverter
.
.
@Converter
public static MyEventBean
toMyEventBean(org.apache.camel.component.file.GenericFile genericFile,
Exchange exchange) throws IllegalArgumentExceptions,
invocationTargetException, IllegalAccessException

the debug when I run my app:
.
.

Stack is tomcat/spring/camel with a maven generated war.

I placed the TypeConverter file in
$PROJECT_HOME/WEB-INF/classes/META-INF/services/org/apache/camel.

That was picked up from the deployed war.

Hi,

Which version of Camel are you using?
Did you deploy the camel application into the web container or OSGi 
platform ?

It will be complicated when you are doing this :)

Has anyone found what the issue us? I placed my TypeConverter with a FQN
entry into all the places I could think it would be picked up including
META-INF/services/org/apache/camel and it doesn't get loaded.

As a test, I opened up the camel-core jar and placed my entry in the
TypeConverter file in the jar. It was picked up fine that way.

Hi

You got any further with this issue?

Have you considered using Camel 2.8.0? It allows you to use the FQN
class name of your custom type converters in the TypeConverter file,
which allows Camel to do pure classpath loading of the converter,
which is faster and more easier than JAR scanning.

See details at
http://camel.apache.org/type-converter.html

I should add that I tried loading the converter class as a bean in my
app-context.xml but that didn't do the trick either.
