You are correct in that adding it should be non-intrusive. I used the bnd
tool[1] to create one from inspecting the JAR. Here's what it came up with:

However, even after adding this and installing FreeMarker as a bundle, I
still get the following error when using Spring Modules 1.1.0-m2 and Spring
MVC 2.5.2.

org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'freemarkerConfig' defined in ServletContext resource
[/WEB-INF/myapp-servlet.xml]: Instantiation of bean failed; nested exception

I don't believe this is a FreeMarker issue, but it might be if there's
something I have wrong in my manifest.

Thanks,

Matt
