FormAPI Error:500

System

here is simple datacapture.cfg I have written to check formapi.
--------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE datacapture SYSTEM "datacapture5.0.dtd">
<data-capture-requirements type="content" name="shoes">
<!-- data-capture-requirements elements contain area elements -->
<ruleset name="TeamSite Templating">
<item name="Date">
<text size="40"/>
</item>
<itemref name="Address"/>
<script>
<![CDATA[
alert ("Hello, world!");
]]>
</script>
</ruleset>
</data-capture-requirements>
----------
Giving me following error
Location: /iw/webdesk/templating/datacapture.jsp
Internal Servlet Error
javax.servlet.ServletException: Address
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:459)
....
...
I can open a DCT w/o problem but also w/o message "Hello, world".
my iw.cfg reads, section..
[teamsite_templating]
# use_java_ui=false
# data_root=templatedata
enable_formapi=true

I have also ran iwreset after changes. Anything missing?
