i find all configuration correct, u can verify also. (i use XE 2.0.3)
can i get a API to list all mapped tables in hibernate ?
1- My xwiki.cfg*
#-# Allow or disable custom mapping for particular XClasses. Custom mapping
may increase the performance of certain
#-# queries when large number of objects from particular classes are used in
the wiki.
*xwiki.store.hibernate.custommapping=1*
#-# Dynamic custom mapping.
*xwiki.store.hibernate.custommapping.dynamic=1*
*
*
*2- My data in custom mapping table*
see the image attached bellow
*3- Simple Query without custom mapping*
*
*
*code *:
*#set($sql = "select doc.fullName from XWikiDocument as doc, BaseObject as
obj where obj.name=doc.fullName and obj.className='XWiki.EmployeeClass' ")*
*
*
*#foreach($EmployeeDoc in $xwiki.search($sql))*
** $familyName*
*#end*
*
*
*Result :*
- XWiki.EmployeeTemplate
- Main.Employee1
- Main.Employee2
*4- Query with custom mapping*
*
*
*
code :
#set($xc = $context.getContext())
#set($sql = "SELECT e.familyName from EmployeeClass e")
#set($familyNames = $xc.getWiki().search($sql , $xc))
#foreach($familyName in $familyNames)
* $familyName
#end
Result :
Caused by: com.xpn.xwiki.XWikiException: Error number 3223 in 3:
Exception while searching documents with sql SELECT e.familyName from
EmployeeClass e
Wrapped Exception: EmployeeClass is not mapped family Name from
Employee Class e?

Try looking at an employee object, with the object
editor
if there is something wrong with the mapping, it will likely throw an error
rather than
give you the information you inputted.
If you used exactly the same fields in the class as the tutorial
and you ran the groovy script
and clicked "To inject custom mapping for this class, click here" here.
(an I assume you did since you have xwikicustom_xwiki_employee table)
then your mapping should be fine.
Are you sure you stopped the server and changed
# xwiki.store.hibernate.custommapping.dynamic=0
to =1
then restarted it.
(this mistake busted me a few times ;) )

Yes, i get xwikicustom_xwiki_employee table
and SELECT * FROM xwikicustom_xwiki_employee; query show me a liste of
my employees.
But i think the mastake is in the mapping.
