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
}
});

Create class that reads in two names and outputs

Create a new program Reverse.java by creating a new class that reads in
two names and outputs them in reverse order. You will need two String
variables name0 and name1 and you will need to use two input dialog boxes.
Don't forget to add a space between the names in the output.
how can i do this?

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
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?
