    <p>Well, it turns out with the release of the Java Plug-in 1.6.0_24 in February 2011, copy and paste from the system clipboard was deemed a security hole and disabled. You can copy and paste BETWEEN applets. But if you try to use something from your main clipboard, it can't be copied in. </p> <p>So there are a couple of options for a workaround. You can roll back to an earlier version of the plug-in. That will work, but chances are all future releases will still keep copy and paste disabled, so you'd never be able to upgrade. </p> <p>The other alternative is to provide a custom java security policy file which enables access to the system clipboard again. </p> <p>First locate your local Java Security Policy file. The file is named java.policy and should be in the lib\security folder of your Java installation. On Windows 7, it can be found at C:\Program Files (x86)\Java\jre6\lib\security. Copy this file to your home folder (ex. C:\Users\Kyle). Rename the file to .java.policy (note the period at the beginning). Edit the file in a text editor. Locate this line of text:</p> <pre><code>// "standard" properies that can be read by anyone </code></pre> <p>Add the following line just below it like so:</p> <pre><code>// "standard" properies that can be read by anyone permission java.awt.AWTPermission "accessClipboard"; </code></pre> <p>Save the file. Close any open browsers and ensure that Java is not running before testing.</p> <p>source: <a href="http://blogs.oracle.com/kyle/entry/copy_and_paste_in_java" rel="nofollow noreferrer">http://blogs.oracle.com/kyle/entry/copy_and_paste_in_java</a></p>

    1. COThank you - I have seen this, but I was under the impression that it had been disabled for UNSIGNED applets only (according to my research). Signed applets should still work - and another signed applet is currently allowing copy and paste. Any more ideas?

    2. COWhat version of java plugin are you using? What browser are you testing this with? Do you get a prompt to allow/disallow the copy/paste service? Have you checked out the clipService demo? http://pscode.org/jws/api.html#cbs

    3. COThis is a applet which is deployed across many JVMs in several corporations. I currently run 1.6.0_26 and I do not get prompted to allow/disallow the copy/paste service. If I add code to handle accessing the system clipboard, it allows me and I can paste into the field.

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.
