public static void main(String[] args) throws Exception {

    XWPFDocument document = new XWPFDocument(new FileInputStream("WordTemplate.docx"));

    replaceFormFieldText(document, "Text1", "Моя Компания");
    replaceFormFieldText(document, "Text2", "Аксель Джоачимович Рихтер");
    replaceFormFieldText(document, "Text3", "Доверенность");

    document.write(new FileOutputStream("WordReplaceTextInFormFields.docx"));
    document.close();
}
}

it misses some string, it not replaces entire document..please help with sample code

I do something similar in my project at https://github.com/centic9/poi-mail-merge which provides a general mail-merge functionality based on POI. It is using a bit different functionality from XmlBeans which replaces strings in the full XML-content of the document instead of each paragraph separately.

    private static void appendBody(CTBody src, String append, boolean first) throws XmlException {
        XmlOptions optionsOuter = new XmlOptions();
        optionsOuter.setSaveOuter();
        String srcString = src.xmlText();
        String prefix = srcString.substring(0,srcString.indexOf(">")+1);

        final String mainPart;
        // exclude template itself in first appending
        if(first) {
            mainPart = "";
        } else {
            mainPart = srcString.substring(srcString.indexOf(">")+1,srcString.lastIndexOf("<"));
        }

        String suffix = srcString.substring( srcString.lastIndexOf("<") );
        String addPart = append.substring(append.indexOf(">") + 1, append.lastIndexOf("<"));
        CTBody makeBody = CTBody.Factory.parse(prefix+mainPart+addPart+suffix);
        src.set(makeBody);
    }
}
