I'm running out of ideas, but it seems as if there are spaces being added to
EmployeeClass
and to familyName. These would definitly break the query.
Maybe possibly it's velocity to blame, I only tested the tutorial in groovy so why not
try:
{{groovy}}
xc = xcontext.getContext();
for(String name : xc.getWiki().getHibernateStore().search("SELECT e.familyName from
EmployeeClass as e", 0,0, xc));
println(name);
}
{{/groovy}}
I also have it going directally to XWikiHibernateStore to run the query.

is there a way to get the list of mapped classes in XWiki or Hibernate APIs
?

You are so close, it is successfully putting data
into the custom mapped
table and
presumably taking it out. The entire problem has to be in the query.
Can you confirm that the EmployeeClass document is in the space XWiki?
You might try "select e.familyName from XWiki.EmployeeClass as e"

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?
