Hi All,
How r u?
I have problem, if any body have solution then please
help me out.
We are making an ERP application. For that we create
EJB and servlet. Database for this server is mySQL and
operating system is Linux.
For deploying EJB we are using JBoss with Tomcat.
In this application we are preparing different
databases for different users, but using same
application files for all users.
Earlier everybody was developing his part and that
part was tested by himself (means by single user).
That time application was working properly.
Now we are integrated all applications. Now 3-4
peoples are doing testing of this application by
logging simultaneously from different terminals as
different users, after login they are connected to
different databases as I told you above that we are
using different databases for different members.
Problem has started now. If coincedently any two
different users form different members access same
application and make changes then it will overwrite
changes on another users database for the record which
having same primary key value. So now it's become very
big problem for us.
Our conclusion on this problem is that as we are using
different databases but same EJB because of that it is
giving problem.
Our conclusion is that it is preparing only one EJB
object for one application. I guess it should prepare
different object for different clients.
If anybody has solution then please do reply.
