    copied!<p>You could use the <a href="https://github.com/plutext/docx4j" rel="nofollow">docx4j</a> library. Here is the documentation for <a href="http://htmlpreview.github.io/?https://github.com/plutext/docx4j/blob/master/docs/Docx4j_GettingStarted.html" rel="nofollow">Getting started</a>.</p> <p>I recommend that you create a template file first, with all the formatting, and as much structure as you can. Then you should put in content-controls where you want your text to go. The content controls could contain other content, that you could use to repeat some common structure.</p> <p>In Word, the <em>Content Controls</em> can be found in the <em>Developer tab</em> on the main ribbon. They are named <em>Rich Text Content Control</em> and <em>Plain Text Content Control</em>. You might need to enable the Developer Tab first though. In the options, under <em>Customize ribbon</em>, check <em>Developer</em>.</p> <p>To change the tag of a Content Control, click its handle on the page to select it, and then press the <em>Control Properties</em> button on the ribbon. You will then get a dialog where you can set the title and the tag.</p> <p>In Java, the content controls will be represented in the object model as <a href="http://www.docx4java.org/docx4j/javadoc-2.6.0/index.html?org/docx4j/wml/SdtBlock.html" rel="nofollow"><code>SdtBlock</code></a> or <a href="http://www.docx4java.org/docx4j/javadoc-2.6.0/index.html?org/docx4j/wml/SdtRun.html" rel="nofollow"><code>SdtRun</code></a>. When you are processing the template, you should replace those with the content you want.</p> <p>The <a href="http://www.docx4java.org/docx4j/javadoc-2.6.0/index.html?org/docx4j/math/package-summary.html" rel="nofollow"><code>org.docx4j.math</code></a> package contains the classes for creating math formulas.</p> <hr> <p>Here is an example:</p> <pre><code>import java.*; import java.io.*; import java.util.*; import javax.xml.bind.*; import javax.xml.namespace.*; import org.docx4j.wml.*; import org.docx4j.math.*; import org.docx4j.openpackaging.packages.*; import org.docx4j.openpackaging.parts.WordprocessingML.*; public class Processor { public static void main(String[] args) throws Exception { File inFile = new File(args[0]); File outFile = new File(args[1]); WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(inFile); MainDocumentPart mdp = wordMLPackage.getMainDocumentPart(); Processor processor = new Processor(); processor.processContent(mdp.getContent()); wordMLPackage.save(outFile); } private Stack&lt;String&gt; tags = new Stack&lt;String&gt;(); private void pushTag(String tag) { tags.push(tag); } private String getTag() { return tags.peek(); } private void popTag() { tags.pop(); } private static final org.docx4j.wml.ObjectFactory wmlFactory = new org.docx4j.wml.ObjectFactory(); private static final org.docx4j.math.ObjectFactory mathFactory = new org.docx4j.math.ObjectFactory(); public void processContent(List&lt;Object&gt; content) { for (Object child : content) { if (child instanceof SdtBlock) { processBlock((SdtBlock) child); } else if (child instanceof P) { processP((P) child); } else if (child instanceof JAXBElement) { JAXBElement&lt;?&gt; elem = (JAXBElement&lt;?&gt;) child; Class&lt;?&gt; elemType = elem.getDeclaredType(); if (elemType.equals(CTOMath.class)) { processOMath((CTOMath) elem.getValue()); } } } } public void processP(P p) { processContent(p.getContent()); } public void processBlock(SdtBlock block) { String tag = block.getSdtPr().getTag().getVal(); pushTag(tag); processContent(block.getSdtContent().getContent()); popTag(); } public void processOMath(CTOMath oMath) { String tag = getTag(); // tag of innermost &lt;w:sdt&gt; if (getTag().equals("MyEquation")) { List&lt;Object&gt; content = oMath.getEGOMathElements(); content.clear(); content.add(makeRun("A=\u03c0")); content.add(makeSSup(makeRun("r"), makeRun("2"))); } } private JAXBElement&lt;CTR&gt; makeRun(String text) { // &lt;m:r&gt; CTR run = mathFactory.createCTR(); List&lt;Object&gt; content = run.getContent(); // &lt;w:rPr&gt;&lt;w:rFonts&gt; RPr pr = wmlFactory.createRPr(); RFonts rFonts = wmlFactory.createRFonts(); rFonts.setAscii("Cambria Math"); rFonts.setHAnsi("Cambria Math"); pr.setRFonts(rFonts); content.add(wmlFactory.createSdtPrRPr(pr)); // &lt;m:t&gt; CTText ctText = mathFactory.createCTText(); ctText.setValue(text); content.add(mathFactory.createCTRTMath(ctText)); return mathFactory.createCTOMathArgR(run); } private JAXBElement&lt;CTSSup&gt; makeSSup(Object expr, Object exp) { // &lt;m:ssup&gt; CTSSup ssup = mathFactory.createCTSSup(); // &lt;m:e&gt; CTOMathArg eArg = mathFactory.createCTOMathArg(); eArg.getEGOMathElements().add(expr); ssup.setE(eArg); // &lt;m:sup&gt; CTOMathArg supArg = mathFactory.createCTOMathArg(); supArg.getEGOMathElements().add(exp); ssup.setSup(supArg); return mathFactory.createCTOMathArgSSup(ssup); } } </code></pre> <p>It will look for block-level content-controls named "MyEquation", and replace the math-expressions in them with <code>A=&pi;r<sup>2</sup></code>.</p> <p>Specifically, it will look for</p> <pre class="lang-xml prettyprint-override"><code>&lt;w:sdt&gt; &lt;w:sdtPr&gt; &lt;w:tag w:val="MyEquation"/&gt; &lt;/w:sdtPr&gt; &lt;w:sdtContent&gt; &lt;w:p&gt; &lt;m:oMath&gt; &lt;/m:oMath&gt; &lt;/w:p&gt; &lt;/w:sdtContent&gt; &lt;/w:sdt&gt; </code></pre> <p>and replace it with</p> <pre class="lang-xml prettyprint-override"><code>&lt;w:p&gt; &lt;m:oMath&gt; &lt;m:r&gt; &lt;w:rPr&gt; &lt;w:rFonts w:ascii="Cambria Math" w:hAnsi="Cambria Math"/&gt; &lt;/w:rPr&gt; &lt;m:t&gt;A=π&lt;/m:t&gt; &lt;/m:r&gt; &lt;m:sSup&gt; &lt;m:sSupPr&gt; &lt;m:ctrlPr&gt; &lt;w:rPr&gt; &lt;w:rFonts w:ascii="Cambria Math" w:hAnsi="Cambria Math"/&gt; &lt;/w:rPr&gt; &lt;/m:ctrlPr&gt; &lt;/m:sSupPr&gt; &lt;m:e&gt; &lt;m:r&gt; &lt;w:rPr&gt; &lt;w:rFonts w:ascii="Cambria Math" w:hAnsi="Cambria Math"/&gt; &lt;/w:rPr&gt; &lt;m:t&gt;r&lt;/m:t&gt; &lt;/m:r&gt; &lt;/m:e&gt; &lt;m:sup&gt; &lt;m:r&gt; &lt;w:rPr&gt; &lt;w:rFonts w:ascii="Cambria Math" w:hAnsi="Cambria Math"/&gt; &lt;/w:rPr&gt; &lt;m:t&gt;2&lt;/m:t&gt; &lt;/m:r&gt; &lt;/m:sup&gt; &lt;/m:sSup&gt; &lt;/m:oMath&gt; &lt;/w:p&gt; </code></pre> <hr> <p>You can make the equation in Word, and look inside the docx-file.
