Body
<p>Work-a-round: The session Id is changing on Firefox and Chrome when the servlet is called from the applet, for some reason. I ended up storing the session ID and setting it on the HttpURLConnection connection to the servlet, which forces the servlet to get the correct backing bean.</p> <p>In the productSelection backing bean:</p> <pre><code>private String sessionID = ""; // With getter . . . FacesContext facesContext = FacesContext.getCurrentInstance(); HttpSession session = (HttpSession) facesContext.getExternalContext().getSession(false); sessionID = session.getId(); </code></pre> <p>On the web page containing the applet I am using a javascript function to wait until the applet is fully loaded before telling it to load a criteria file, which will be modified by the user and then sent back to the backing bean for processing. I have simply passed the session ID along with the criteria file to the applet:</p> <pre><code><SCRIPT language="javascript"> function waitUntilLoaded() { if (document.criteriaApplet.isActive()) { var object = document.getElementById ("criteriaApplet"); criteriaApplet.loadCriteriaFile((object.codeBase + "#{productSelection.productUsage.searchCriteriaObjectUrl}"), "#{productSelection.sessionID}"); } else { settimeout(waitUntilLoaded(),500) } } </SCRIPT> </code></pre> <p>In the applet button code, to submit the modified criteria file back to the backing bean via the servelet, I added the session ID to the HttpURLConnection connection:</p> <pre><code>HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoInput(true); connection.setDoOutput(true); connection.setUseCaches(false); connection.setRequestMethod("POST"); connection.setRequestProperty("Content-Type", "application/x-java-serialized-object"); connection.setRequestProperty("Cookie","JSESSIONID=" + sessionID); ObjectOutputStream out = new ObjectOutputStream(connection.getOutputStream()); out.writeObject(searchSubmitObject); out.flush(); out.close(); </code></pre>

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.
