Docx4j Test - No File is Output - docx4j

Question

Attempting to write my first class with docx4j (http://www.docx4java.org). Basically the idea is to find a string of text in the .docx file and replace it with another string of text. Essentially a mail merge. While I'm not receiving any errors, the merged document itself is not being saved in the path I've suggested. This makes me think it's a file path problem but I don't see anything wrong with it.
package efi.mailmerge.servlets;
import java.util.List;
import javax.xml.bind.JAXBElement;
import org.docx4j.openpackaging.exceptions.Docx4JException;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;
import org.docx4j.wml.Text;
public class WordDocTest {
/**
* Open word document /Users/Jeff/Development/ReServe-Unleashed/Dev/MailMerge/uploads/Sample.docx, replace a piece of text and save
* the result to /Users/Jeff/Development/ReServe-Unleashed/Dev/MailMerge/uploads/Sample-Out.docx.
*
* The text <<CUS_FNAME>> will be replaced with John.
*
* #param args
*/
public static void main(String[] args) {
// Text nodes begin with w:t in the word document
final String XPATH_TO_SELECT_TEXT_NODES = "//w:t";
try {
// Open the input file
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new java.io.File("/Users/Jeff/Development/ReServe-Unleashed/Dev/MailMerge/uploads/Sample.docx"));
// Build a list of "text" elements
List texts = wordMLPackage.getMainDocumentPart().getJAXBNodesViaXPath(XPATH_TO_SELECT_TEXT_NODES, true);
// Loop through all "text" elements
for (Object obj : texts) {
Text text = (Text) ((JAXBElement) obj).getValue();
// Get the text value
String textValueBefore = text.getValue();
// Perform the replacement
String textValueAfter = textValueBefore.replaceAll("<<CUS_FNAME>>", "John");
// Show the element before and after the replacement
System.out.println("textValueBefore = " + textValueBefore);
System.out.println("textValueAfter = " + textValueAfter);
// Update the text element now that we have performed the replacement
text.setValue(textValueAfter);
}
wordMLPackage.save(new java.io.File("/Users/Jeff/Development/ReServe-Unleashed/Dev/MailMerge/uploads/Sample-Out.docx"));
} catch (Docx4JException e) {
Logger.getLogger(WordDocTest.class.getName()).log(Level.SEVERE, null, e);
e.printStackTrace();
} catch (Exception e) {
Logger.getLogger(WordDocTest.class.getName()).log(Level.SEVERE, null, e);
e.printStackTrace();
}
}
}
On lines 26 and 50 you can see the input/output paths. I've confirmed that the Sample.docx input file does exist and that the uploads directory has write permissions. Can you see anything wrong with my file paths here? I could be completely on the wrong path, but this is all very new to me so I'm learning as I go.
Any and all help is very much appreciated.

At first sight, I would suggest trying with your path written the following way :
wordMLPackage.save(new java.io.File("\\Users\\Jeff\\Development\\ReServe-Unleashed\\Dev\\MailMerge\\uploads\\Sample-Out.docx"));
If it still not works, please provide the stack traces ? It could help. (if no doc is saved, there must be an exception thrown)
