Hmmm, it seems to work now for adding the file to the folder. See my
code below. I was contrasting it to my code that previously didn't work.
Maybe it was because I didn't put in the JcrConstants.NT_FILE
before?
```java
Node root, folder;
root = session.getRootNode();
folder = root.getNode("bar");
Node child = folder.addNode("grade.png", JcrConstants.NT_FILE);
Node content = child.addNode(JcrConstants.JCR_CONTENT,
JcrConstants.NT_RESOURCE);
// Set the property for the node.
content.setProperty(JcrConstants.JCR_DATA,
root.getSession().getValueFactory().createBinary(new
FileInputStream("grade.png")));
content.setProperty(JcrConstants.JCR_MIMETYPE,
"image/png");
Calendar rightNow = Calendar.getInstance();
content.setProperty(JcrConstants.JCR_LASTMODIFIED, rightNow);
```

"There are two ways of constructing a software design. One way is to
make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
