Problem in creating composite widget and including in Liferay project

[11年前 に Shahriar Khondokar によって更新されました。]

Hi all
this is what we have done so far:

• We created a GWT Composite widget project successfully
• Next created a jar of this composite widget project
• Included the jar in the lib folder of the Liferay project and indicated the jar in the buildpath using Eclipse
• Also attached the source in the jar

However when we build the project, we get error "package not found"

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.ServiceDefTarget;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.HTML;
import com.google.gwt.user.client.ui.RootPanel;
import com.prolexic.commonCompositeWidget.client.CommonCompositeWidget;

public class DataGridServiceEntryPoint implements EntryPoint {

private static final String rootNodeId = "gridView";

@Override
public void onModuleLoad() {
CommonCompositeWidget mycomposite = new CommonCompositeWidget("This is the GWT Composite portlet.");
RootPanel rootPanel = RootPanel.get(rootNodeId);
rootPanel.add(mycomposite);
//rootPanel.add(new HTML("This is the <b>GWT chat rooms</b> portlet."));
}

}
