Interactive Brokers API - Executing multiple trades

I'm trying to create a program for an API to place multiple trades at once, and then get prices for the stocks, and then rebalance every so often. I used a tutorial from online to get some of this code, and made a few tweaks.
However, when I run the code, it often connects and will place an order if I restart IB TWS. But if I go to run the code again it does not work, or show any indication that it will connect. Can anyone help me figure out how to keep the connection going, so that I can run the main.java file, and it will execute multiple trades and then end the connection? Do I need to change the client id number in either the code, or the settings of TWS?
There are three files:

I changed a few things around in the code and added comments.

QuickBooks NULL CallbackHandler

I'm trying to perform a batch operation in QuickBook but getting null callbackhandler.

When I debug, in execute method, I'm getting Null BatchOperation in return. I'm not sure performing Batch operation is allowed in sandbox environment.

I found the solution after so much of testing and communication with Quickbooks Devs thought would be helpful for others.
In sandbox environment even if you set the config properties to sandbox URL it still picks as PROD URL in Callbackhandler.
Config.setProperty(Config.BASE_URL_QBO, "https://sandbox-quickbooks.api.intuit.com/v3/company");
In this case they called this as a bug, currently all you can do is to make a trial account in PROD and then test this.

Queues and Stacks Hiring and Firing

I finished this program and demo for my TA. I completely forgot one thing. So, the program is about hiring and firing people using stack and queues. I figured everything out except for one thing. I have to hire at least 3 people and whoever the first applicant is, I will hire them first so on. Here's the problem:
When I fire someone (The last person hired), that person should be the next person to get hired. Example:
Fired Name: b SS: 2
next person hired should be
Hired Name: b SS: 2.
I can't figure out how to get the last person fired to be the next person hired. Here's my program:
class Person {
public String name;
public String SS;
public Person(String N, String S) {
this.name = N;
this.SS = S;
}
}
class Manager {
Scanner keyboard = new Scanner(System.in);
private Queue<Person> app = new Queue<Person>();
public Stack<Person> hire = new Stack<Person>();
public Stack<Person> fire = new Stack<Person>();
public void Apply() throws QueueException {
System.out.print("Applicant Name: ");
String appName = keyboard.nextLine();
System.out.print("SSN: ");
String appSS = keyboard.nextLine();
Person apply = new Person(appName, appSS);
app.enqueue(apply);
}
public void hire() throws QueueException {
if (!app.isEmpty()) {
Person newHire = hire.push(app.dequeue());
System.out.println("Hired \nName: " + newHire.name + " SS: " + newHire.SS);
//hire.push(app.dequeue());
} else if (!fire.isEmpty()) {
Person newFire = app.dequeue();
System.out.println("Hired \nName: " + newFire.name + " SS: " + newFire.SS);
} else {
System.out.println("Nobody to hire.");
}
}
public void fire() throws StackException {
if (!hire.isEmpty()) {
Person newFire = fire.push(hire.pop());
System.out.println("Fired \nName: " + newFire.name + " SS: " + newFire.SS);
fire.push(hire.pop());
} else {
System.out.println("Nobody to fire");
}
}
}
public class Management {
public static void main(String[] args) throws QueueException, StackException {
Scanner keyboard = new Scanner(System.in);
Manager user = new Manager();
boolean test = true;
while (test) {
System.out.print("Press \n\t1 ACCEPT APPLICANT");
System.out.print("\n\t2 Hire \n\t3 Fire \n\t4 Quit:");
System.out.print("\nAnswer: \n");
int action = keyboard.nextInt();
String space = keyboard.nextLine();
if (action == 1) {
user.Apply();
} else if (action == 2) {
user.hire();
} else if (action == 3) {
user.fire();
} else if (action == 4) {
System.exit(0);
} else {
System.out.println("Please try again.");
}
}

you have this error on the hire() method.
Person newFire = app.dequeue();
you see that you are executing this line even tho app queue is Empty. just use fire stack instead of app queue.
public void hire() throws QueueException {
if (!app.isEmpty()) {
Person newHire = hire.push(app.dequeue());
System.out.println("Hired \nName: " + newHire.name + " SS: " + newHire.SS);
//hire.push(app.dequeue());
} else if (!fire.isEmpty()) {
Person newFire = fire.pop();
hire.push(newFire);
System.out.println("Hired \nName: " + newFire.name + " SS: " + newFire.SS);
} else {
System.out.println("Nobody to hire.");
}
}

asynccallback failures

In my app I need to add string vallues to the file(.property file, if it is important). and user enter this values in gwt GUI. Here is it's important part:
final Button submit = new Button("Submit");
addButton(submit);
submit.addSelectionListener(new SelectionListener<ButtonEvent>() {
#Override
public void componentSelected(ButtonEvent ce) {
keyWord.selectAll();
regexp.selectAll();
if (keyWord.getValue() != null){
setKeyWord(customerId, keyWord.getValue());
keyWord.setValue("");
}
if (regexp.getValue() != null){
setRegExp(customerId, regexp.getValue());
regexp.setValue("");
}
}
});
}
private void setKeyWord(final String customerId, final String keyword){
final AsyncCallback<String> callbackItems = new AsyncCallback<String>() {
public void onFailure(final Throwable caught) {
Window.alert("unable to add " + caught.toString());
}
public void onSuccess(final String x) {
Window.alert(x);
}
};
serverManagementSvc.setKeyWords(customerId, keyword, callbackItems);
}
private void setRegExp(final String customerId, final String regexp){
final AsyncCallback<String> calbackItems = new AsyncCallback<String>() {
#Override
public void onFailure(Throwable throwable) {
Window.alert("unable to add " + throwable.toString());
}
#Override
public void onSuccess(String s) {
Window.alert(s);
}
};
serverManagementSvc.setRegExp(customerId, regexp, calbackItems);
}
So I need to use Asunccallback to call methods which are in the "server part".
here are these methods:
//adds a new keyword to customers properties
public String setKeyWords(String customer, String word){
try{
PropertiesConfiguration props = new PropertiesConfiguration("/home/mikhail/bzrrep/DLP/DLPServer/src/main/resources/rules.properties");
String newKeyWord = new String(props.getString("users." + customer + ".keywords" + "," + word));
props.setProperty("users." + customer + ".keywords", newKeyWord);
props.save();
}catch (ConfigurationException e){
e.printStackTrace();
}
return "keyword " + word + " added";
}
// adds a new regexp to customer properties
public String setRegExp(String customer, String regexp){
try {
PropertiesConfiguration props = new PropertiesConfiguration("/home/mikhail/bzrrep/DLP/DLPServer/src/main/resources/rules.properties");
String newRegValue = new String(props.getString("users." + customer + ".regexps" + "," + regexp));
props.setProperty("users." + customer + ".regexps", newRegValue);
props.save();
} catch (ConfigurationException e){
e.printStackTrace();
}
return "regexp " + regexp + " added to " + customer + "'s config";
}
all interfaces are present.
when I run my code And press "submit" button in gui I see that both asynccallback failured(Window.alert, as you can see, shows "null pointer exception" despite of the fact that values which I send to methods are not null). why can it be? can you suggest me something?
UPD here is error which is shown by firebug:
uncaught exception: java.lang.ClassCastException
function W8(){try{null.a()}catch(a){return a}}

the problem is solved: there were a simple mistake in the code. I've closed brackets at the wrong place:
//adds a new keyword to customers properties
public String setKeyWords(String customer, String word){
try{
PropertiesConfiguration props = new PropertiesConfiguration("/home/mikhail/bzrrep/DLP/DLPServer/src/main/resources/rules.properties");
String newKeyWord = new String(props.getString("users." + customer + ".keywords") + "," + word);
props.setProperty("users." + customer + ".keywords", newKeyWord);
props.save();
}catch (ConfigurationException e){
e.printStackTrace();
}
return "keyword " + word + " added";
}
// adds a new regexp to customer properties
public String setRegExp(String customer, String regexp){
try {
PropertiesConfiguration props = new PropertiesConfiguration("/home/mikhail/bzrrep/DLP/DLPServer/src/main/resources/rules.properties");
String newRegValue = new String(props.getString("users." + customer + ".regexps") + "," + regexp);
props.setProperty("users." + customer + ".regexps", newRegValue);
props.save();
} catch (ConfigurationException e){
e.printStackTrace();
}
return "regexp " + regexp + " added to " + customer + "'s config";
}

I recommend that you recompile the GWT code using
-style PRETTY
and then check that firebug output again; it may give you a better clue, compared to your updated uncaught exception.
Next, I suggest you run it in the eclipse debugger, and set breakpoints in both the client and server code, and then you can inspect the variables and step through the code.

Bluecove: SERVICE_SEARCH_DEVICE_NOT_REACHABLE issue

I try to connect to a custom Bluetooth device using BlueCove. I can pair the device, but when I try to search for services I always get SERVICE_SEARCH_DEVICE_NOT_REACHABLE in serviceSearchCompleted() and no services are discovered. If I try the same thing outside Java (in Windows), the PC bluetooth device discovers and can connect (using COM21, COM22, ...) to the SPP service on my device.
What am I doing wrong?
I also tried to do the service search after the device discovery is ended. Same issue.
Please find below my code.
Many thanks in advance for any idea on how to solve this,
Adrian.

I had the same problem while connecting to a Bluetooth earpiece. Like you I was also searching for more than one service at a time and It always returned SERVICE_SEARCH_DEVICE_NOT_REACHABLE. So, I tried searching for only one service and it worked. So, try modifying your code as:
...
private static final UUID[] UUIDS = new UUID[] {new UUID(0x0003)}
