Error "Only a type can be imported...resolves to a package"

Victor AMORIM : Error "Only a type can be imported...resolves to a package"
I develope an struts portlet to interact with an MySql database.
I use the plugin SDK and the service builder.
I began to create my service.xml, i have used the service-buider, I have added the methods to create a new entry in the database in "". And I have used a second time the service-builder.
I have deployed with Ant, when i have started the Tomcat server I have this error:
To resolve this problem I try to import alls classes like:

<%@ page import="com.portlet.annuaire.service.*" %>

<%@ page import="com.portlet.annuaire.model.*" %>

But it did not work.
My Configuration:

Eclipse Europa

Liferay-portal-5.2.3 with Tomcat 6.0.18

Thanks in advance.
A Gupta :
Instead of using "com.liferay.annuaire.*", try to use specific files(like com.liferay.annuaire.classname) you want to use. There might be some files in that directory that can't be imported.
Victor AMORIM : Thanks for your reply.
When I have the error I importe juste the classes that I need:
<%@ page import="com.portlet.annuaire.model.EntreeAnnuaire" %>
<%@ page import="com.portlet.annuaire.service.EntreeAnnuaireLocalServiceUtil" %>
This code produce the error that is describe above.
Mazhar Anwar :
Can you make sure YOUR_PORTLET/WEB-INF/lib folder contains YOUR-PORTLET-NAME-service.jar file?
Victor AMORIM : No, when I deploy with ant the PORTLET-NAME-service.jar is gone. I don't know when it disapears. I thing its when I use the service-builder.
How can I produce the jar?
`Mazhar Anwar :
When you do ANT BUILD_SERVICE, On successful build, it will generate the YOUR-PORTLET-NAME-service.jar inside PORTLET-FOLDER/docroot/WEB-INF/lib folder which contains all model and service classes for the portlet and you can use them in your jsp as in previous posts.
Victor AMORIM : You're right, the ant product the jar, but when I deploy it disappears and should not be imported into the server. That why I have the error in my first post, I think.
Victor AMORIM : That's good, thanks a lot.
To resume the MY-PORTLET-NAME-portlet-service.jar was create when I use the service-builder but when I deploy with ANT the jar are deleted.
I do a copy of this jar, and I past it directly in the tomcat directory ("...\ext\servers\tomcat\liferay-portal-5.2.3\tomcat-6.0.18\webapps\PORTLET_FOLDER\docroot\WEB-INF\lib\".
That's resolves the problem "Only a type can be imported..."
Now I have another problem:
I'll do some research on this problem.
