Grouper Developers Forum

["caleb racey" <>]

I believe the error message is diagnostic that the initial grouper webservice 
sanjay was trying to use  was compiled against a hibernate2 based api 
(1.2.0). The net.sf.hibernate  prefix is hibernate2, with hibernate3 the 
prefix changes to org.hibernate.   I think this is fixed by compiling against 
a newer api version though sanjay will be able to confirm.
 
IIRC most of the dialect variants for mysql from hib3 aren't present in hib2, 
certainly mysql5 wasn't there when i last looked.      I believe the upgrade 
from hib2 to hib3 in 1.3 will enable easy out of the box use with mysql5 and 
we shall certainly be testing this on release, being a mysql5 shop. 
 
hope this clears up the confusion 
 
regards

Cal

Hmm. There appear to be several MySQL dialect variants in Hib3:

MySQLDialect
MySQLInnoDBDialect
MySQLMyISAMDialect
MySQL5Dialect
MySQL5InnoDBDialect

Did you try the appropriate one from this list, ie, probably one with a
"5" if MySQL v5 or without if not?

I'm very interested in getting to the bottom of this, as others will
surely want to run grouper 1.3.0 with MySQL.
