I have postgresql 9.4 and glassfish 4.1. Besides I use MyBatis inside EJB. Now I try to make select from table and this is what I get:

I even tried the following code:
SqlSession session =ConnectionFactory.getSession().openSession(false);//AUTOCOMMITList list=null;
try{
session.getConnection().setAutoCommit(false);
TempMapper mapper =(TempMapper)session.getMapper(TempMapper.class);
list=mapper.readAll();
}catch(SQLException ex){Logger.getLogger(TempBean.class.getName()).log(Level.SEVERE,null, ex);}
finally{
session.close();}
However the result is the same. When I used gf+mysql+mybatis I changed relaxautocommit but for postgresql driver there is no such attribute. How to solve it?

Best guess, based on experience, is that somehow you're disabling autocommit on a different
connection from the one where you're doing the commit. I've seen this sort of thing happen
with connection poolers where the developers don't fully understand how the connection pool
works.

You could confirm this by turning on full query logging in Postgres and see which connection
does what. If it turns out to be the case, then you'll have sort out how your code is
getting confused.

If it's not the case, then I don't have any other ideas, but the full query logging will
also tell you whether the command to disable autocommit really is being issued to
PostgreSQL as well ... so still might be useful.
