problem with migration code

Hi,
I am facing problem as I have to run a code genrated by talend studio in JAVA, my problem is, while importing the Java packages or Jar files i am not getting any error but there are some more import statements which I think related to talend, shows error as my IDE is not detecting fully classified name of the imported classes.
Below is the code which is showing problem.
import routines.talenddemosjava.sample;
import routines.talenddemosjava.sss;
import routines.DataOperation;
import routines.Mathematical;
import routines.Numeric;
import routines.Relational;
import routines.StringHandling;
import routines.TalendDataGenerator;
import routines.TalendDate;
import routines.TalendString;
import routines.system.*;
Imports without problem :
import org.talend.core.context.*;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import java.math.BigDecimal;
import java.io.ByteArrayOutputStream;
import java.io.ByteArrayInputStream;
import java.io.DataInputStream;

I have tried to find routines jar or lib but could not find it so I am not able to add it externally in the system.
Please help me and let me know how can I get the routines so that all the classes it contain can be imported properly?
Thanks in advance.
