Hi Andrew, 

thanks for the note. I think this is by far the best
solution. 

Here is what worked for me (the JSP 2.5 and Facelets docs
are not very good on this). I added
"META-INF/bamboo.taglib.xml" with the following contents:

<?xml version="1.0"?>
<!DOCTYPE facelet-taglib PUBLIC
  "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
  "http://java.sun.com/dtd/facelet-taglib_1_0.dtd">
<facelet-taglib xmlns="http://java.sun.com/JSF/Facelet">
	<namespace>http://bamboo-ag.com/helpers</namespace>
	<function>
	<function-name>concat</function-name>
	
<function-class>bamboo.util.LittleHelpers</function-class>
	<function-signature>
	java.lang.String concat(java.lang.String,
java.lang.String)
	</function-signature>
	</function>
</facelet-taglib>

then

<html xmlns:bb="http://bamboo-ag.com/helpers" ...>
...
	#{bb:concat("it ", "works")}
	
worked as expected.
