    <p><strong>Disclosure: I lead the docx4j project</strong></p> <p>Although docx4j can also handle pptx and xlsx, it is mostly used for docx manipulation. By way of illustration, as at the time of writing, there are nearly 1000 topics in the <a href="http://www.docx4java.org/forums/docx-java-f6/" rel="noreferrer">docx4j forum</a>. The pptx forum has only 10% of the volume.</p> <p>Whatever you want to do with the docx document, docx4j ought to be able to help you. There's a <a href="http://www.docx4java.org/blog/2013/05/docx4j-in-a-single-page/" rel="noreferrer">single page overview</a> of a generic workflow.</p> <p>For many common requirements, docx4j provides higher level API. These include:</p> <ul> <li><p>Create/open/save docx (of course)</p></li> <li><p>Report/document generation, using a variety of approaches: (i) Variable substitution, (ii) XML data binding (particularly strong), and (iii) Mailmerge</p></li> <li><p>Export as HTML, XHTML</p></li> <li><p>Export as PDF (with font support)</p></li> </ul> <p>For anything else, you can manipulate the JAXB representation of the docx to your heart's content. JAXB is a Java community standard, included in Java 6, and with a strong alternative implementation in EclipseLink's MOXy. (POI uses XML Beans instead of JAXB)</p> <p>There's a <a href="http://www.docx4java.org/blog/2013/05/docx4jpptxxlsx-online-code-generation/" rel="noreferrer">web app</a> to help you explore a docx, and generate Java code to create corresponding Java objects.</p> <p>Of course, if there is some specific task you have in mind, it may be that docx4j or POI has a particular strength there.</p> <p>Both docx4j and POI are ASL v2 licensed.</p> <p>docx4j is actively maintained; its source code is <a href="https://github.com/plutext/docx4j/" rel="noreferrer">on GitHub</a>. </p> <p>In addition, commercial support is available for docx4j if you want it, as are several commercial extensions eg <a href="http://www.plutext.com/m/index.php/products" rel="noreferrer">MergeDocx</a>.</p> <p>docx4j does rely on POI as a library for <a href="http://poi.apache.org/poifs/index.html" rel="noreferrer">its implementation</a> of the OLE 2 Compound Document format, which we're grateful for.</p>

    1. COAll processing comes from the XML parsing right ? can I for example interactively use word document through docx4j . like if I want to search certain text and select the result exactly as search box does ?

    2. COThe XML is unmarshalled into JAXB objects; processing is then generally done at that level. docx4j is a library. To use it interactively, you'd have to make an interactive application. docx4all is an example of an interactive application (a wordprocessor) based on docx4j. With docx4j, you can search for text, and do stuff with the results.

    3. CODoes docx4j have support for tables within docx files? I just tried for example to create a purchase order docx file and convert it to pdf and the table was really badly formatted. I used the sample webapp on the docx4j website at: http://webapp.docx4java.org/OnlineDemo/docx_to_pdf_fop.html

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
