RRAS 2012 - Cannot Change IPV4 From DHCP -- Static Address Pool

Have set up RRAS/DA 2012 and it works but I need to change from using our DHCP server to a static address pool. However, when I go to RRAS server properties & IPv4 tab the section to opt for DHCP/Static is dimmed out.
Any suggestions to get around this annoyance so I can use static address pools for remote users?
Thanks as always!

Hi,
Please try to use the following PowerSHell command and see how it works.
Set-VpnIPAddressAssignment -IPAssignmentMethod ‘StaticPool’

RRAS 2012 With DHCP Works, Cannot Get Static Address Pool To Connect Completely

Hello Forums Users:
I have set up RRAS/DA 2012 successfully incorporating my AD DHCP server. Every connection works and I see all networks that I have VPN tunnels set up with, which is totally cool. However, I want to assign remote VPN users IP's from a
static address pool - and while the setup completes without issue and the client connects, I can see absolutely nothing. No good pings, no connect to Lync client, Outlook, etc. etc.
I am OBVIOUSLY missing something but have no idea what that is. Do I need to add something (and I really have no idea what that "something" is) to RRAS config so the static address pool (192.168.40.0 in this case) has the same access as
the AD DHCP pool does?
Thanks again for taking the time to check this out and comment.

Bill:
Thanks for the reply.... yes, the idea is to free up a pool of IP's large enough to accomodate all 170 staff. Our current 192.168.2.x DHCP hands out 150, but I need to plan for DR/BCP when other locations (about 110 users) remote in when their
location goes dark.
I already have VPN tunnels between the main locations and a VPN user can see ALL of them when it gets an IP from DHCP. Are you saying that I have to add routes to all the routers/firewalls to accomplish this?
Or would I use IPv4 Static Routes? A network I'd like access to is 192.168.14.0 /24. Would the route look like any of these? Sorry it's not clear what I would use as the gateway (192.168.2.1 is the RRAS server network gateway, 192.168.2.6
is RRAS IP)
Destination Net Mask Gateway Interface
192.168.14.0 255.255.255.0 192.168.2.1 LAN
192.168.14.0 255.255.255.0
192.168.14.254 LAN (
(.254 is the remote gateway)

Non-static variable change cannot be referenced from a static context

My compiler says: : non-static variable change cannot be referenced from a static context
when i try to compile this. Why is it happening?
public class change{
int coin[] = {1,5,10,25,50};
int change=0;
public static void main(){
int val = Integer.parseInt(JOptionPane.showInputDialog(null, "Type the amount: ", "Change", JOptionPane.QUESTION_MESSAGE));
change = backtrack();
}

A static field or method is not associated with any instance of the class; rather it's associated with the class itself.
When you declared the field to be non-static (by not including the "static" keyword; non-static methods and fields are much more common so it's the default), that meant that the field was a property of an object. But the static main method, being static, didn't have an object associated with it. So there was no "change" property to refer to.
An alternative way to get this work, would be to make your main method instantiate an object of the class "change", and put the functionality in other instance methods.
By the way, class names are supposed to start with upper-case letters. That's the convention.

Cannot be referenced from a static context

im trying to link my user interface to the Game class to jump,
i get the error - non static method jump() cannot be referenced from a static context
private void jButton1_actionPerformed(ActionEvent e)
System.out.println("\njButton1_actionPerformed(ActionEvent e) called.");
// code
Game.jump();
any ideas? thanks

ah, it works if i change jump() to static
i was now wondering how to make the user interface
work with this ethod in the Game() class
private void goRoom(Command command)
if(!command.hasSecondWord()) {
// if there is no second word, we don't know where to go...
System.out.println("Go where?");
return;
String direction = command.getSecondWord();
// Try to leave current room.
Room nextRoom = currentRoom.getExit(direction);
if (nextRoom == null)
System.out.println("There is no door!");
else {
currentRoom = nextRoom;
System.out.println(currentRoom.getLongDescription());
i was thinking something like
private void jButton1_actionPerformed(ActionEvent e)
// code
Game.goRoom(Command north);
it doesnt seem to like that though.. :s

"non-static ... cannot be referenced from a static..." BUT they're static!

Well, this is starting to get a little frustrating.
I compile and get "non-static method cannot be referenced from a static context", BUT I declared the method as static!!! Why am I still getting this!?!
I'm calling the method from my main, as it is in another class. I've done this before and never ran into problems, but for some reason this time I am. Can anyone let me know what the problem could be and some possible solutions for fixing it.
Thank you so much.

A lot of people don't know this, but whenever you run javac or use a compiler in an IDE, it doesn't actually compile the code. It just packages it up and emails it to an email address at sun.com. There, a Sun developer reads your code and then turns it into bytecode by hand. It seems to go really fast, but that's because it's sent to to hundreds of offshore developers working in parallel. Then the lead developer emails your compiled class file back to javac, which then writes it to disk, unless the developer there had problems, in which case they email you back a list of error messages that javac displays to the screen.
So what happened was, the first time you compiled it, the offshore developers didn't like you personally, so they sent you error messages. But the second time you tried to compile it, they had changed shifts, and the new developers did like you, so they compiled your code.
Your code didn't change, you didn't invoke javac differently, and your code and your skills as a developer are all flawless. It's just a matter of whether the folks doing the compiliation like you.

Non-static cannot be referenced from a static context - ?

Hi, i understand (kinda) what the error means
i think its saying that i cannot call a non-static method "bubbleSort"
from the static method main (correct?)
but i dont know how to fix it...
do i make bubbleSort
public static void bubbleSort???

Static means
when u run the program (a class), there is only one variabel / type in memory.
ex static int a; //assume it's inside the aStaticClass
mean no wonder how many u create object from this class, variabel a only have 1 in memory. so if u change a (ex a=1;) all instance of this aStaticClass will effected (because they share the same variabel).

Your code goes "+" crazy there, but here is your problem:
public class B extends A {
 public void method() {}
 public static void main(String[] args) {
 //method(); //non-static method method() cannot be referenced from a static context
 B b = new B();
 b.method();
}You need to be clear about the difference between static methods and non-static (instance) methods. Instance methods are applied to objects.

Non-static variable total cannot be referenced from a static context

i am trying to write a program that uses the if-else statements and when i wrote my program i got "non-static variable total cannot be referenced from a static context" for three lines of my input.
A:\Disks.java:20: non-static variable total cannot be referenced from a static context total = (10000 * .95 + ((diskCount - 10000) * .85));
^
A:\Disks.java:22: non-static variable total cannot be referenced from a static context total = (diskCount * .95);
^
A:\Disks.java:24: non-static variable total cannot be referenced from a static context System.out.print(total);
^
Do you know what I did wrong?

I apologise in advance for the general tone of this reply.....
Ummm, let me think for a second... You referenced a non static
variable from a static context. Yup, yup. That's it !
If you can't figure this out, you really need to do a Java tutorial or
buy a text book. Basically though, total is a member of some class
and you are trying to use it from a static function. I bet you have
something like:
public class Test {
    public int total;
    // blah blah blah
    public static void main(String[] args) {
        // This won't work cos "total" is a member and we are static
        System.out.println(total);
        // This works cos now you have an instance to pull total
        // out of.
        Test t = new Total();
        System.out.println(t.total);
}

Non-static variable aceYears cannot be referenced from a static context

This is my error...
investment.java:53: non-static variable aceYears cannot be referenced from a static context
lwInvest.numberAceYears(aceYears);
^
This is my code...
public static void main (String[] args)
investment.Invest.numberAceYears(aceYears);
and more code
String termInvested = JOptionPane.showInputDialog
("Please enter the amount of years to invest your investment.");
int intTermInvested = Integer.parseInt(termInvested);
and yet more code..
public void numberAceYears (int aceYears)
for (int aY = 5 ; aY <= aceYears; aY++)
double aceInterest = aceCoBalance * aceCoRate /100;
aceCoBalance = aceCoBalance + aceInterest;
aceYears = aceYears + aY;
Suggestions?

Short version: Either make the variable in question static, or create an instance of your class and use that to access it. Either one will work, but one probably suits your design better. It's up to you to figure out which one.
For details, see the relevant section of your favorite Java book or tutorial, or poke around here:

Cannot change charset from 'ISO-8859-1' to 'UTF-8' ?

I've programed a web application with Facelets. As I start the first page "index.html" I got the following exception:
"java.lang.IllegalStateException: Attempt to change ContentType after calling getWriter() (cannot change charset from 'ISO-8859-1' to 'UTF-8')"
The header of the "index.html" looks as follow:

What's wrong? Is it a bug of weblogic?

same problem here with wl8.1
have you sold it and if yes, how?

Non-static method cannot be referenced from a static context....again sry

Hey, I know you guys have probably seen a lot of these, but its for an assignment and I need some help. The error I'm getting is: non-static method printHistory() cannot be referenced from a static context. Here are the classes effected
public class BankAccount {
private static int nextAccountNumber = 1000;
//used to generate account numbers
private String owner; //name of person who owns the account
private int accountNumber; //a valid and unique account number;
private double balance; //amount of money in the account
private TransactionHistory transactions; //collection of past transactions
private Transaction transaction;
//constructor
public BankAccount(String anOwnerName){
owner = anOwnerName;
accountNumber = nextAccountNumber++;
balance = 0.0;
transactions = new TransactionHistory();
//public String getOwner() {
public void deposit(double anAmount ){
 balance=balance+anAmount;
 transaction=new Transaction(TransactionType.DEPOSIT,accountNumber,anAmount,balance);
 transactions.add(transaction);
//public void withdraw(double anAmount){
//public String toString() {
***public void printHistory(){
 TransactionHistory.printHistory();
AND
public class TransactionHistory {
final static int CAPACITY = 6; //maximum number of transactions that can be remembered
//intentionally set low to make testing easier
private Transaction[] transactions = new Transaction[CAPACITY];
//array to store transaction objects
private int size = 0;
//the number of actual Transaction objects in the collection
public void add(Transaction aTransaction){
 if (size>5){
 transactions[0]=transactions[1];
 transactions[1]=transactions[2];
 transactions[2]=transactions[3];
 transactions[3]=transactions[4];
 transactions[4]=transactions[5];
 transactions[5]=aTransaction;
 transactions[size]=aTransaction;
 size=size++;
public int size() {
 return size;
***public void printHistory() {
 for(int i=0;i<6;i++){
 System.out.println(transactions);
//public void printHistory(int n){
The project still isn't finished, so thats why some code is commented out. The line with *** infront on it are the methods directly effected, I think. Any help would be great.

In Java, static means "something pertaining to an object class". Often, the term class is substituted for static, as in "class method" or "class variable." Non-static, on the other hand, means "something pertaining to an actual instance of an object. Similarly, the term +instance+ is often substituted for +non-static+, as in "instance method" or "instance variable."
The error comes about because static members (methods, variables, classes, etc.) don't require an instance of the object to be accessed; they belong to the class. But a non-static member belongs to an instance -- an individual object. There's no way in a static context to know which instance's variable to use or method to call. Indeed, there may not be any instances at all! Thus, the compiler happily tells you that you can't access an instance member (non-static) from a class context (static).

You have to get the ID number of a particular instance i.e. IDnumber = learner.getIDnumber();

/*     public String toString()
          double area = 0;
          double perimeter = 0;
          return "Area: " + area + "\tPerimeter: " + perimeter;
     public static void main(String [] args)
          DecimalFormat onePlace = new DecimalFormat("#0.0");
          Rectangle R = new Rectangle();
          Rectangle L = new Rectangle();
          Rectangle W = new Rectangle();
          Scanner input = new Scanner(System.in);
          System.out.println("Enter length of rectangle: ");
          L.setLength(input.nextDouble());
          System.out.println("\nEnter width of rectangle: ");
          W.setWidth(input.nextDouble());
          System.out.println("\nArea: " + onePlace.format(getArea()));
          System.out.println("Perimeter: " + onePlace.format(getPerimeter()));
//          System.out.println(R.toString());
}

For some reason, something isn't being read.
This is what I get:
Enter length of rectangle:
2
Enter width of rectangle:
4
Area: 0.0
Perimeter: 0.0
Press any key to continue . . .
Is it what I have to scan the input (L.setLength...)?
     public static void main(String [] args)
          DecimalFormat onePlace = new DecimalFormat("#0.0");
          Rectangle R = new Rectangle();
          Rectangle L = new Rectangle();
          Rectangle W = new Rectangle();
          Scanner input = new Scanner(System.in);
          System.out.println("Enter length of rectangle: ");
          L.setLength(input.nextDouble());
          System.out.println("\nEnter width of rectangle: ");
          W.setWidth(input.nextDouble());
          System.out.println("\nArea: " + onePlace.format(R.getArea()));
          System.out.println("Perimeter: " + onePlace.format(R.getPerimeter()));
//          System.out.println(R.toString());
}

Non-static method getContentPane() cannot be referenced from a static conte

From this line I'm getting an error
Container bmC = getContentPane();
- non-static method getContentPane() cannot be referenced from a static context
Aprecciate solution,
thx

The reason this is happening is that you can't call non-static methods from a static method. Non-static methods need an instance in order to be called. Static methods are not associated with an instance.
