COL3.
SELECT COL1, COL2, COL3 FROM SCM.TBL WHERE COL1=?

Note on Class Names
When installing multiple EJB applications on the same machine, if there is a class (such as HOME
interface, Remote interface, Enterprise Bean class, and primary key class) that has the same name but
different implementation, the incorrect operation occur. Therefore, when developing EJB applications,
determine a package name so that the class name does not get duplicated.
Starting EJB Applications
In DB access environment definition of the customize tool, if the same port number of the existing
product is specified by mistake, much time is required for starting and an error occurs. Specify a correct
port number and restart.
About the EJB Application Process
In the EJB application, do not control the signal by JNI (Java Native Interface). When the signal is
controlled, it does not operate correctly.
