Hi Doug: In: /proj/adaptive/www/course/f00/hw/1/scratch-graph I had to write things like: Main { (@ public static EDU.neu.ccs.demeter.dj.ClassGraph buildClassGraph() { EDU.neu.ccs.demeter.dj.ClassGraph cg=new EDU.neu.ccs.demeter.dj.ClassGraph(); I could not just use ClassGraph, although I put import EDU.neu.ccs.demeter.*; // class dictionary into *.cd Where do I have to do the import? -- Karl
