You can access any Java library in the scripting and expression environment. As long as you precede any Java package with the Packages string, or use the importPackage method, you would write it as you would any Java routine.

So, you could drop a data element in, and do something like:

var input = new Packages.java.io.BufferedReader(new Packages.java.io.FileReader("text.txt"));
var line = "";
var stringBuilder = new Packages.java.lang.StringBuilder();

while (( line = input.readLine()) != null){
stringBuilder.append(line);
}

input.close();
stringBuilder.toString();

That might take some minor tweaking due to Javascript differences, but thats the basic idea.
