How can I store in database an user Session attribute along with other informations provided in the same form?
<p:outputLabel value="user ID:" for="informer" />
<p:inputText id="informer" value="#{session.getAttribute('userID').toString()}"
title="informer" disabled="true" />
I've already tested with disabled="false", too, but only the Session attribute is saved as NULL, though it appears in the form field. The other fields are saved properly.

context.getELContext().getELResolver().getType(context.getELContext(), null, "value")
Here "value" is an attribute name. By this we can get data type of the attribute.
By somehow can we set the type also?

I don't know how to read the attribute maxLenth. The way in the image I have done drive me to the error below.!
Piece of XSL:
<?xml version="1.0" encoding="UTF-8"?>
<c:message xmlns:c="ictt"><c:de format="B" lengthField="0" name="BIT MAP, PRIMARY" number="000"/>
<c:de format="B" lengthField="0" maxLength="008" minLength="008" name="BIT MAP, SECONDARY" number="001" subFields="00"/>
Piece of Java Code:
int length = Integer.parseInt(spec.getAttribute("maxLength"));

We've implemented the Whitelist and there's an application I need to use the Force attribute with, however, I'm unable to get this to work. As I read it, this code says use Java 1.6_24 for Example.com and any other applications are blocked from running. There are three versions of Java installed - 1.6_24, 1.7_65 & 1.8_25. The Java console shows 1.8_25 being called.
Here's the ruleset.
<ruleset version="1.1+"> <rule> <id location=https://example.com />
<action permission="run" version="1.6_24" force="true" /> </rule>
<rule> <id /> <action permission="block">
<message> This application is blocked due to Java restrictions, please contact the Service Desk for assistance.</message> </action> </rule></ruleset>
I also tried
<action force="true" permission="run" version="1.6.0_24" />
and also
<action force="true" version="1.6.0_24" permission="run" />.
The Java console is still showing version 1.8.0_25.

I have the below code with spaces on uri and prefix (directive attribute).
<%@ taglib uri=" news.tld" prefix=" news" %>
how to fix without altering the JSP? Can i handle with web.xml or any other property available.
I have hundreds of jsp like this and wanted to handle without code fixes.
I tried JSP trimSpaces but it fixes the namespace but not the attributes.

I'm looking to figure out if it's possible to do the following:
HttpSession session = request.getSession();
session.setAttribute('name', 'Jane_Doe');
// more code here
session.setAttribute('name', 'John_Doe');
Obviously, you can use the HttpSessionAttributeListener to determine which attribute has changed. However, it doesn't return the new value but rather the old one.
You can use the HttpSessionEvent listener to determine when a session object has been changed.
Is there a way you can determine when a session object changes (and it does NOT occur when the setAttribute method is called...) and determine the updated key:value pair?

Being new to java I am a bit lost as to why my session attribute for this banking app wont add the deposits to the session var... it just keeps going back to the amount I set it to originally - so if I set the beginning balance to 3000 then deposit 100 it becomes 3100, but if I then try deposit another amount eg. a extra 200 it becomes 3200 not 3300 like it should be !!

I am generating java script tag and javascript code in servlet and displaying it in each jsp page. i include this in every jsp in my application. I am preparing the following javascript content and diplayin each jsp
<script type="text/javascript"> BOOM.addVar (clientId = SOME universal unique ID ) </script>
the clientid will be uniqueid it gets generated every time.
Here my question is, is there any possibility the clientId will be store in browser cache or third party cache server. if yes how to prevent clientId from cache.
I don't want to prevent the whole jsp file from cache. i just want to prevent only that particular field. so that i can use advantages cache and also prevent particular header field to be cached.
Also can we prevent particular http header attribute from cache.

Sample XML:
XML Code:
<Books>
<Book id="1" Name="C#">
<URL>http://localhost/download/M1.xml</URL>
</Book>
<Book id="2" Name="Oracle">
<URL>http://localhost/download/M2.xml</URL>
</Book>
<Book id="3" Name="Archius">
<URL>http://localhost/download/M3.xml</URL>
<URL>http://localhost/download/M4.xml</URL>
</Book>
</Books> mh_sh_highlight_all('xml');
I have to fetch only the book name attribute and use it for display .However say for example ,I have got the list of Books ie(C#,Oracle,Archius) ,passing this value to a method should return me an array of URL nodes value within it.
The idea is to display the book names in a list and then on user selection , corresponding URL needs to be fetched.
Was able to get the loop for traversing the nodes
[java=code]
NodeList nodeList = document.getDocumentElement().getElementsByTagName ("Book");
for (int i = 0; i < nodeList.getLength(); i++) {...
[java=code]
So
a) Display the BookNames
b) Get the corresponding URL's for the particular book if I pass the Bookname

In a form i used <h:commandButton> i called a Javascript function. Though the function returns false , form is submitted and action method is called. I used like this
<h:commandButton onclick="test();" action="{#bean.menthod}">
test- javascript method returns boolean value false.
Above doesn't work. Below mentioned code alone worked. I want to know why
<h:commandButton onclick="if(test) return true;else return false" action="{#bean.menthod}">

Well I fixed my invalid path problem
Now it is telling me that my file is not found and it is exactly where I put it and told JCreator to look for it.
this is what I get:
javac: file not found: C:Program FilesJavajdk1.8.0docsMyName.java
when I go manually to the address, it is there but for some reason Jcreator cannot find it.

While doing trial and error got caught in the below scenario.
public class Crypt {
public static void main (String args[])
{
/*all I want is calculate a binary number (ex -: 22 , 34) using decimal base (10n).
*So, I have to convert 2 p into 10n form so I have to find n in terms of p . We have x as the input.
* The formula works as below.
*2p =10n
*p ln (2) =n ln (10)
*n = p [ln(2) / ln(10)]
*2 p = 10 p [ln(2) / ln(10)]

I'm trying to establish an SSL connection (using a self-signed certificate). However, I can't seem to get the handshake to work. At the moment server side, I've created the public/private key + signed certificate and then stored them in a KeyStore. I've also stored this signed certificate in a KeyStore (trustStore) client side, so it can compare.
Keys: RSA, Certificate Sig: SHA256withRSA, cipherSuite: TLS_RSA_WITH_AES_128_CBC_SHA
Client Code
// 34393570706261
SSLContext context = SSLContext.getInstance("TLS");
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(client_trustStore);
context.init(null, tmf.getTrustManagers(), new SecureRandom());
SSLSocketFactory socketFactory = context.getSocketFactory();
conn = (SSLSocket) socketFactory.createSocket("localhost", port);
String[] suites = new String[]{"TLS_RSA_WITH_AES_128_CBC_SHA"};
conn.setEnabledCipherSuites(suites);
