Hi,

I've developped two applications
--- Step 1 ---

Database is MySQL with InnoDB table type
I'm using Hibernate 2.1.3

I start both applications

--- Step 2 ---
Application #1
Session session = HibernateUtil.currentSession();
Transaction tx = beginTransaction();
Object obj = new Obj();
session.save(obj);
tx.commit();
HibernateUtil.close();

Application #2
Session session = HibernateUtil.currentSession();
List objectList = session.find( "from Object as object WHERE object.code=(?)", code, Hibernate.STRING);
HibernateUtil.close();
First query succeeded, the new object is well selected

Application #1
Session session = HibernateUtil.currentSession();
Transaction tx = beginTransaction();
Object obj = new Obj();
session.save(obj);
tx.commit();
HibernateUtil.close();

Application #2
Session session = HibernateUtil.currentSession();
List objectList = session.find( "from Object as object WHERE object.code=(?)", code, Hibernate.STRING);
HibernateUtil.close();
Second query failed, the new Object is not found

I suppose it is a concurrency error because of when I execute the same sequence in the same application, it works
What can i do to resolve this error ?

is my request not well explained ?
need more details ?

system with two applications, one application add data by a call to save and the second get data by a call to find function
The second call to find() does not find the new data ... that are stored into database
is it a cache error ?
how does find() work ?
thanks a lot
sorry for my english

are you using second level cache?

I did not know .... how can I get the info

reading the doc

Parles tu francais ?
I look, but it seem i don't use second cache level
Is there a default second cache configured in hibernate ?

I saw that hibernate use EHCache by default by i did not specify use of cache in my mapping file...

if you don't configure class cache configuration, there is no reason why a second level should be used.
Are you using one hibernate session per httprequest or do you keep it in httpSession for example.
The best way to manage this hibernate session is to used threadlocal pattern (see open session in view on site).
Yes i speak french and even if my english is bad, let's talk english, this is an english forum.
