Hi

I´m falling from one pitfall to next.
I get following error during deploying to Jboss 4.0.2:

2005-07-01 22:54:18,940 INFO [org.hibernate.jmx.HibernateServiceMBean] Could not build SessionFactory using the MBean classpath - will try again using client classpath: could not find PropertyAccessor class: public
2005-07-01 22:54:18,940 DEBUG [org.hibernate.jmx.HibernateServiceMBean] Error was
org.hibernate.MappingException: could not find PropertyAccessor class: public
at org.hibernate.property.PropertyAccessorFactory.resolveCustomAccessor(PropertyAccessorFactory.java:103)

Please tell me, if you need more Informations!
Best regards

Hibernate version:
3.0.5

Name and version of the database you are using:

MySQL, version: 4.0.21

The generated SQL (show_sql=true):
Static SQL for entity: de.test.pps.VoAbteilung2
Version select: select dbKey from ABTEILUNG2 where dbKey =?
Snapshot select: select voabteilun_.dbKey, voabteilun_.ABTEILUNGSNAME as ABTEILUN4_0_ from ABTEILUNG2 voabteilun_ where voabteilun_.dbKey=?
Insert 0: insert into ABTEILUNG2 (ABTEILUNGSNAME, dbKey) values (?, ?)
Update 0: update ABTEILUNG2 set ABTEILUNGSNAME=? where dbKey=?
Delete 0: delete from ABTEILUNG2 where dbKey=?
Identity insert: insert into ABTEILUNG2 (ABTEILUNGSNAME) values (?)

Debug level Hibernate log excerpt:

I found the solution for the problem,

posting for others falling into.

I used access="public" in a property definition.
Removing it was the solution.
