Hi Mr Steve Swinsburg, i am his co-worker, we are doing some
expansion for the Profile2 project. At this time, we are creating a new
page in the display screen ( same as My profile, Connections,
Search....) this page is using for display all grades of student have
had. Whenever he come to this page, he can see all his grades profile.
Cause we do not want to change the original project, we created some
new class in the package org.sakaiproject.profile2.tool.pages . at this
time, we can get a LinkedList<String> of all site id of all
course that one user joined and display it on my new page. Cause the
siteId is also the gradebookUid, we try to use the GradebookService to
get all the Assignment of each site, and at this state we encountered
the problem.
I created a new class called MyGradebookApi to inject the GradebookService in to our application. For testing i've create two method
public int getNumberOfAss(String gradebookUid){
return gradebookService.getAssignments(gradebookUid).size();
}
and......
public LinkedList<String> getAssNameList(String gradebookUid){
LinkedList<String> assNameList =new LinkedList();
LinkedList<Assignment> assList = new LinkedList();
List<Assignment> tempList = gradebookService.getAssignments(gradebookUid);
assList.addAll(tempList);
while(!assList.isEmpty()){
Assignment tempAss = assList.remove();
String name = tempAss.getName();
assNameList.add(name);
}
return assNameList;
}
but
it seem the GradeBookService do not work, i created a cousre site, i
got its siteId, i created some sample Assignment, then in my page, i
called the method getNumberOfAss and try to display in my page, but
nothing happened.
The tool deployed sucessful, cause i modified the pom.xml to add some dependencies.
In my class i imported:
import org.sakaiproject.service.gradebook.shared.*;
import org.sakaiproject.service.gradebook.shared.Assignment;
//import org.sakaiproject.tool.gradebook.Assignment;
import org.sakaiproject.assignment.api.*;
import java.util.LinkedList;
import java.util.List;
and create a private variable: private GradebookService gradebookService;
Did i miss any step? Could you give me some advices please?
Thanks and regards

If using Spring, inject the actual API, not the static cover. However, don't inject into the tool.
Since you seem to be modifying Profile2, inject the GradebookService into SakaiProxy.java which is where I have kept all Sakai related API calls. That is already injected into all Tool pages so you can just call sakaiProxy.someMethod() to do things.
Could you let me know what additions you are making to Profile2? Are you wanting to contribute them back to the main release of Profile2?
cheers,
Steve
