Why I should define a JLabel before a addActionListener?

Why I should define a JLabel before a addActionListener?

I have one JLabel and one JButton into JFrame. I write code for
actionPerformed event of JButton like following:
btnOK.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
lblA.setText("Hello"); // error here
}
});
final JLabel lblA = new JLabel("");
but i get following error:
lblA cannot be resolved
however if I placed define of JLabel before addActionListener like
following my problem solved:
final JLabel lblA = new JLabel("");
btnOK.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
lblA.setText("Hello"); // error here
}
});

Injecting html snippet with JQuery into existing html page

Injecting html snippet with JQuery into existing html page

I want to inject certain html snippet with JQuery into existing html page.
Existing snippet:
<table class="course hoverHighlight">
<tbody>...</tbody>
...
</table>
I want to inject:
<thead>
<tr>
<th class="title">Course</th>
<th class="author">Author</th>
<th class="level">Level</th>
<th class="rating">Rating</th>
<th class="duration">Duration</th>
<th class="releaseDate">Released</th>
</tr>
</thead>
before tbody tag.
<table class="course hoverHighlight">
<thead>...</thead>
<tbody>...</tbody>
</table>
I have tried this code but it didn`t work:
function() {
var theadInjection= $("<thead>
<tr>
<th class="title">course</th>
<th class="author">author</th>
<th class="level">level</th>
<th class="rating">rating</th>
<th class="duration">duration</th>
<th class="releasedate">released</th>
</tr>
</thead>");
$( '.course' ).prepend(theadInjection);
}
Simple injection like this one did work:
function() {
var theadInjection= $("<thead></thead>");
$( '.course' ).prepend(theadInjection);
Thanks.

Passing PCI Scan on apache 2.2.22

Passing PCI Scan on apache 2.2.22

We are on Ubuntu 12.04 and apache 2.2.2 version. We had PCI scan done on
our site and 2 vulnerabilities came out that we can not get under control.
First one is BEAST attack and other one SSL RC4 Cipher Suites Supported.
So far I have tried following that looks promising. I tried with few more
changes after searching for help, but those changes in turn started
breaking browsers and were discarded.
SSLProtocol -SSLv2 -TLSv1 +SSLv3
SSLHonorCipherOrder On
SSLCipherSuite
ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-RC4-SHA:ECDHE-RSA-RC4-SHA:ECDH-ECDSA-RC4-SHA:ECDH-RSA-RC4-SHA:ECDHE-RSA-AES256-SHA:RC4-SHA:!MD5:!aNULL:!EDH
SSLCompression off
or
SSLProtocol ALL -SSLv2

SSLCompression off
Based on scan results on ssllabs, I am able to get only one of the
vulnerability mitigated. What changes I need to do so that both
vulnerabilities are addressed and does support current version of
browsers?

would like to keep this dialog box, but I want to customize the message it
displays. Can this be done?
