Problems retrieving object elements using jpath (flowscript)

[beyaNet Consultancy]

Hi,
I have a flowscript which does the following:

cocoon.sendPage("registered_section1", {"userGlobal":userGlobal});

where userGlobal is a user object. I try to retrieve elements within the java object inside my xsp page by saying:

<jpath:value-of select="userGlobal.getUserName()"/>

but am getting the following error message:

org.apache.commons.jxpath.JXPathException: Cannot invoke extension function userGlobal.getUserName; userGlobal

What am I doing wrong?
