Apologies, reading my filestructure back, it looked a bit like
src/com/pdata lived within the ant folder, which it does not. I've tried
to make this a bit clearer below. Apologies for the spam.

/ant
/build.xml (main build xml that I use to clean the project from
tomcat and copy files over to the webapps directory)
/src/com/pdata
/PersonData.java
/PersonDataAction.java
/Webroot
/pages
/error.jsp
/personData.jsp
/results.jsp
/Welcome.jsp
/WEB-INF
/classes

/PersonData.class
/PersonDataAction$Forwards.class
/PersonDataAction.class
/MessageResources.properties
/lib (bunch of library files, can define these if
needed?)
/src
/java/MessageResources.properties
/build.xml (supplied by struts-blank and not
used)
/README.txt

/validation.xml
/web.xml

If there's any other useful information I can provide, please let me
know. Thanks for the help so far
Thanks

hi,
You don't have to define properties form in struts-config when you use
classic ActionForm.
it will be enough :
...
<form-bean name="personDataForm" type="com.pdata.PersonData"/>
