I am using ISMP 11.5 SP1. While I am using it in our code, getting compilation problems and unable to resolve them. I wanted to know which jars have to be added to build path to resolve this. The following are some of the lines (highlighted in RED) which are not getting resolved.

import com.installshield.util.*;
import com.installshield.wizard.service.*;
import com.installshield.product.service.product.*;

public class TestDetails extends AsynchronousWizardAction {

I have added jars under <ISMP_installed_location>/lib/ to the build path. Still not able to resolve the above mentioned lines. Requesting advise on which jars have to be included.
