AbstractScmAdvisor - How do you read changed file content?

I have have looked at many references and have not been successful in getting the code to read the content in a IFileItem.  Many examples are for Client side libraries, and others don't seem to compile, or if they compile, they fail to get a service.

See References:
https://jazz.net/forum/questions/8246/read-content-of-specific-file-in-repository (looks like client lib)
https://jazz.net/forum/questions/896/problems-while-using-icontentservice (missing how to get IContentService).
https://jazz.net/forum/questions/69047/icontentserviceretrievecontent (server, but answer not complete)

I have the IScmService:

                /*
                 * Details about the files in the changeSets must be retrieved from the scm service..
                 * IMPORTANT:  This advisor must inherit from AbsctractScmAdvisor to have access to this.
                 */
                IScmService scmService = getService(IScmService.class);

And I can get each file out of the Change sets:

                // Process files....          
                for (IChange change : (List<IChange>) changeSet.changes()) {
                        IVersionableHandle versionableHandle = change.beforeState();
                        // No Before state?  Must be New file so get After State....
                        //        For new files, LocateAncestors returns none, so you only get the file name.
                        if (versionableHandle == null)
                            versionableHandle=change.afterState();
                       
                        // versionableHandle has been class FileItemHandleImpl.
                        IVersionable item = (IVersionable) scmService.fetchState(versionableHandle, null, null);

                        FileItem fitem = (FileItem) item;                      
                        IFileContent content = fitem.getContent();

What do I use to read the content?

I did a toString() on the fitem and content, if that helps...
