Hello Sanjeev,
Thank you very much for your response.
Since the bean class code is big, I am pasting only the code for
ejbPostCreate() and ejbcreate() here.
****************************************************************************
*******************
public class myebsbean implements EntityBean {
protected EntityContext ctx;
public Integer empno;
public String name;
public String dsgn;
public Properties env;
public myebsbean() { }
public void ejbPostCreate(Integer no, String name, String dsgn) throws
CreateException, RemoteException { }
public myebsPK ejbCreate(Integer no, String name, String dsgn) throws
CreateException, RemoteException {
PreparedStatement pstmt = null;
Connection conn = null;
try {
System.out.println("ejbCreate() called");
System.out.println("trying to insert " + no + name + dsgn + "into db" );
this.empno = no;
this.name = name;
this.dsgn = "";
System.out.println("Trying to get the connection");
conn = getConnection();
System.out.println("Got the connection");
pstmt = conn.prepareStatement("insert into EMPDATA (empno, name, dsgn)
values (?,?,?)");
pstmt.setInt(1,no.intValue());
pstmt.setString(2,name);
pstmt.setString(3,dsgn);
System.out.println("trying to insert " + empno + " " + name + " " + dsgn +
"into db" );
if (pstmt.executeUpdate() != 1) {
String error = "JDBC did not create any row";
throw new CreateException (error);
}
System.out.println("Inserted statements into database from Create");
return new myebsPK(no);
}
catch (Exception e) {
System.out.println("New object not created");
throw new CreateException(e.toString());
}
finally {
try {
pstmt.close();
}
catch(Exception e) {}
try {
conn.close();
}
catch(Exception e) {
System.out.println("Exception in finally of ejbCreate()");
}
}
} // end of ejbCreate
} // end of myebsbean class
