Yeah, that's a trap for novices, it was a little gotcha for me few days ago
;) The search parameter is called sql but in fact when you're using
Hibernate store you're supposed to supply hql query, not the sql. And this
is quite misleading since in Hibernate we can execute both hql and sql
queries.
I think you'd have to create Hibernate mapping for Employee entity to use
XWiki.search method. I'm not sure how to pass sql query to the Hibernate
store.
Kind regards

That tutorial is for creating a hibernate mapping for the Employee entity.
There are numerous little mistakes which will make it fail rather silently,
resulting in the "you haven't mapped employee" error.

Can you get a list of tables in your database? There should be a table called
xwikicustom_xwiki_employee
Did you run the test command from the sql console?
SELECT * FROM xwikicustom_xwiki_employee;

Yes, i get xwikicustom_xwiki_employee table
and SELECT * FROM xwikicustom_xwiki_employee; query show me a liste of

But i think the mastake is in the mapping.

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 ;) )

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"

is there a way to get the list of mapped classes in XWiki or Hibernate APIs
?
2009/12/5 Caleb James DeLisle <calebdelisle(a)lavabit.com>
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 :

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.

I use another way to do successfully qeries with this plugin
http://xwikisql.gradsoft.ua/docs/XWikiSqlPluginGuide.html
I think there are a bug "Dynamic Custom Mapping" in XE 2.0.3, I'll try to
add him in JIRA.
Thank you.

Hibernate might have been updated since I wrote the tutorial, I'll try the tutorial
myself.

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.

I have repeated the problem, What is happening is that the mapping is not staying after
the server is reset. It can be made to work by running:
{{groovy}}
xc = xcontext.getContext();
xc.getWiki().getHibernateStore().injectCustomMappings(xc);
{{/groovy}}
every time the server is reset before running the query, but that is far from an optimal
solution.
This problem is particularly confusing because I am sure I tested the tutorial, but there
was
no change made to the storage mechanism since I wrote it.
Thank you for bringing this to my attention, I will adjust the tutorial to reflect it.
