Hi
I need 2 connect to two database and read/write data to both.
For this issue i creates a jdbc.properties like this :
In spring.xml I created bean like this :
if I want to implement DAO classes which uses database 1 , the code is like :
and if I want to Implement BO classes which uses database 1 , the code is like :
for using databse 2 ,
I changed the transactionManager1 to transactionManager2 in BO classes and I changed sessionFactory1 to sessionFactory2 in DAO classes.
but I can't use this and it gives me error. what is the best solution ?
Regards
