For the task in Post #1 (open a Word template and populate fields) the choice depends on format and runtime environment. For DOCX (Word 2007+), editing the OpenXML with a Java library is the most portable route (Apache POI XWPF or docx4j); commercial engines such as Aspose.Words offer fuller fidelity for complex templates. Legacy binary .doc support is limited (HWPF) — convert to DOCX when possible or use Windows-only COM automation for desktop apps. 's POI suggestion is a solid starting point; 's token idea is workable but needs care. (poi.apache.org)

Practical gotchas: Word often splits what looks like one piece of text into multiple XWPFRun objects (formatting, spell/grammar, edits). That makes naive run-by-run string replacement unreliable. Two pragmatic tactics are common: (a) use a library feature that handles run-splitting (docx4j's VariableReplace/VariablePrepare or a mail-merge API), or (b) with POI, replace the whole paragraph text and recreate runs (simpler but loses per-run styling). The tradeoffs should guide the choice. (javadoc.io)

Minimal POI pattern (paragraph-level replace; preserves structural layout but not run-level styling):

try (XWPFDocument doc = new XWPFDocument(new FileInputStream("template.docx"))) {
  for (XWPFParagraph p : doc.getParagraphs()) {
    String text = p.getText();
    if (text != null && text.contains("${name}")) {
      text = text.replace("${name}", "Alice");            // multiple placeholders OK
      for (int i = p.getRuns().size() - 1; i >= 0; i--) p.removeRun(i);
      XWPFRun r = p.createRun();
      r.setText(text);
    }
  }
  try (FileOutputStream out = new FileOutputStream("out.docx")) { doc.write(out); }
}

For simply launching the filled file in the user's Word client, use Java's Desktop API (Desktop.open), which hands the file to the platform's associated app. For server-side generation, avoid automating Microsoft Office via COM (unsupported for server automation); prefer POI/docx4j or a licensed server library.

Opening the document is the easy part, it's just a file after all ;)

Interpreting it is hard. There's a library by the Apache group (Jakarta project) which offers partial capabilities to read and write Word documents http://jakarta.apache.org/poi/index.html but if that is not enough you're pretty much on your own (I think they'd be happy to accept contributions towards completing their work).

hmmm. I think when you name your fields you want to fill like this "<[(myfield1)]>" etc you have a great chance to fill your document without any word interpreter. Only stupid string-replacement. Try it.

Its interessting wether it works for me, too.

Let me know.
