Hey, as i recently said in another post i have just started using netbeans and currently working my way through the book the netbeans platform developers guide. However im currently stuck on a section that uses the following code :

Java Code:
private Task testtask = new TaskImpl();
The TaskImpl class cannot be found even after i have added the following dependencies : Progress API,Utilities API and Lookup.

I have also used : import org.netbeans.modules.progress.spi.TaskModel;
In the class file im trying to create TaskImpl in, this made the Task class available but not TaskImpl.

Any help would be good :)
