    <p>I'm working on a web page that displays a pdf file that needs to be updatable via a (JSF) file upload. My question is, how can I set my webpage up so that this new uploaded file actually takes the place of the old one?</p> <p>I have the file upload working so that an admin user can upload a different pdf file to replace the one currently displayed, sending the pdf to a folder in my tomcat server, with the same filename as the one previously displayed. I did this because I know you can't save the pdf to a resource file within the web application, as these are not dynamically loaded while the application is running. I am using the following HTML to display the pdf: </p> <pre class="lang-html prettyprint-override"><code>&lt;object id="pdf" data="uploads/folder/replaceable.pdf" type="application/pdf" width="100%" height="100%"&gt; &lt;p&gt;It appears you don't have a PDF plugin for this browser. No biggie... you can &lt;a hRef="uploads/folder/replaceable.pdf" onClick="updatePDF();"&gt;click here to download the PDF file.&lt;/a&gt;&lt;/p&gt; &lt;/object&gt; </code></pre> <p>I've seen <a href="https://stackoverflow.com/questions/8885201/uploaded-image-only-available-after-refreshing-the-page">Uploaded image only available after refreshing the page</a> and <a href="https://stackoverflow.com/questions/8516387/how-i-save-and-retrieve-an-image-on-my-server">How I save and retrieve an image on my server in a java webapp</a> and see that this can be accomplished using <code>&lt;Context&gt;</code> tag to retrieve the file similarly to how I have <code>data="uploads/folder/replaceable.pdf"</code>, but I don't know anything about the <code>&lt;Context&gt;</code> tag and haven't been able to get this to work</p>

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.
