How to import a java class

Question

Hi
I want to know how can i import some java classes to my application.
I'm trying to write a little class as:
package paco.view;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
import oracle.jbo.domain.ClobDomain;
public class ClobConverter implements Converter {
public ClobConverter() {
public Object getAsObject(FacesContext context,
UIComponent component,
String value) {
if (context == null || component == null) {
throw new NullPointerException("FacesContext and UIComponent can not be null");
if (value == null) {
return null;
try {
return new ClobDomain(value);
} catch (Exception ex) {
final String message =
String.format("Unable to convert boolean value \"%s\" into a oracle.jbo.domain.Number",
value);
throw new ConverterException(message, ex);
public String getAsString(FacesContext context,
UIComponent component,
Object value) {
if (context == null || component == null) {
throw new NullPointerException("FacesContext and UIComponent can not be null");
return value.toString();
but I'got this message:
Error(3,8): class javax.faces.component.UIComponent not found
Error(4,8): class javax.faces.context.FacesContext not found
Error(5,8): class javax.faces.convert.Converter not found
Error(6,8): class javax.faces.convert.ConverterException not found
What should I do?
Thanks in advance

You need to add the faces library to you project. To do this, select the project properties, go to libraries and class path and select the faces library.
Using JDev you can also choose one or more project technologies (project properties->technology scope) which will add the needed libraries to the project.
