Interactive Broker Java API

Everytime before I place a new order to IB, I need to make a request to IB for next valid orderId and do Thread.Sleep(500) to sleep for 0.5 seconds and wait for IB API's callback function nextValidId to return the latest orderID. If I want to place multiple orders out, then I have to naively do thread.sleep multiple times, This is not a very good way to handle this, as the orderID could have been updated earlier and hence the new order could have been placed earlier. And what if the orderID takes longer time to update than thread sleep time, this would result in error.
Is there a more efficient and elegant way to do this ?
Ideally, I want the program to prevent running placeNewOrder until the latest available orderID is updated and notify the program to run placeNewOrder.
I do not know much about Java data synchronization but I reckon there might be a better solution using synchronized or wait-notify or locking or blocking.
my code:
// place first order
ib_client.reqIds(-1);
Thread.sleep(500);
int currentOrderId = ib_wrapper.getCurrentOrderId();
placeNewOrder(currentOrderId, orderDetails); // my order placement method
// place 2nd order
ib_client.reqIds(-1);
Thread.sleep(500);
int currentOrderId = ib_wrapper.getCurrentOrderId();
placeNewOrder(currentOrderId, orderDetails); // my order placement method
IB EWrapper:
public class EWrapperImpl implements EWrapper {
...
protected int currentOrderId = -1;
...
public int getCurrentOrderId() {
return currentOrderId;
}
public void nextValidId(int orderId) {
System.out.println("Next Valid Id: ["+orderId+"]");
currentOrderId = orderId;
}
...
}

You never need to ask for id's. Just increment by one for every order.
When you first connect, nextValidId is the first or second message to be received, just keep track of the id and keep incrementing.
The only rules for orderId is to use an integer and always increment by some amount. This is per clientId so if you connect with a new clientId then the last orderId is something else.
I always use max(1000, nextValidId) to make sure my id's start at 1000 or more since I use <1000 for data requests. It just helps with errors that have ids.
You can also reset the sequence somehow.

This means that if there is a single client application submitting
orders to an account, it does not have to obtain a new valid
identifier every time it needs to submit a new order. It is enough to
increase the last value received from the nextValidId method by one.

You should not mess around with order ID, it's automatically tracked and being set by the API. Otherwise you will get the annoying "Duplicate order id" error 103. From ApiController class:
public void placeOrModifyOrder(Contract contract, final Order order, final IOrderHandler handler) {
if (!checkConnection())
return;
// when placing new order, assign new order id
if (order.orderId() == 0) {
order.orderId( m_orderId++);
if (handler != null) {
m_orderHandlers.put( order.orderId(), handler);
}
}
m_client.placeOrder( contract, order);
sendEOM();
}

Using Selenium with Java to Automate, how to I make an object oriented part of a script "actionable?"

I have automated a new customer form for work, but there are a lot of options and based on how questions are answered , different fields need to be filled out. Rather than just make a copy of the code and make a different script for each option, I'd like to do this by passing values to a class that determines what options are chosen based on what is passed in. I'm trying to figure most of this out myself and I'm somewhat of a n00b, but if someone can get me past the first hurdle, I'd like to tackle the rest of the hurdles myself.
So I want to start by just doing one line of the script this way, and eventually I will do more. Up front, it is going to seem like a lot of code just to do this, but here is the line:
driver.findElement(By.id("OrganizationName")).sendKeys("The Rolling Stones");
Here is what I have so far:
ncformPage1 skifootz = new ncformPage1("Rolling Stones");
skifootz.getOrgname();
That is the part that is in the script. Here is the class I wrote:
public class ncformPage1 {
private String orgName;
public ncformPage1(String on) {
orgName = on;
}
public String getOrgname() { return "driver.findElement(By.id(\"OrganizationName\")).sendKeys(\""
+ orgName + "\");";
}
}
So when I run this, it goes right past that organizationName element and leaves it blank, does all the other elements, and then fails because organization name is a required field. So I added this bit of code here to see what it prints out to the console:
System.out.println( skifootz.getOrgname());
Sure enough, it prints out
driver.findElement(By.id("OrganizationName")).sendKeys("Rolling Stones");
Which is exactly what I want returned. (I think the last semicolon is extraneous in this case, but at least it returned what I wanted!) But it doesn't execute that. I've tried all kinds of stuff to get it to execute, such as removing driver from what is returned and appending it here instead:
driver.skifootz.getOrgname();
but that gives me skifootz cannot be resolved or is not a field. I tried this:
String a = skifootz.getOrgname();
driver.a();
But that just made a get underlined in red saying method a() is undefined for the type Webdriver. So then I changed String a to Webdriver a:
WebDriver a = skifootz.getOrgname();
driver.a();
But now skifootz.getOrgname(); is underlined saying "type mismatch: cannot convert from String to WebDriver." I've been messing around with it for a few days now, and I haven't gotten any closer. Maybe this is an easy solution, but if I can just get this part working then perhaps I can move on to the next phase? This n00b thanks everyone in advance for any help anyone can give.

The method is returning a String type and you expect it to act like a driver object. That part is incorrect.
I think you can write methods to be more like
public WebElement getOrgname(WebDriver driver, String OrganizationName) {
return driver.findElement(By.id(OrganizationName));
}
WebElement a = skifootz.getOrgname(driver);
a.sendKeys("Rolling Stones");
OR
public void TypeText(WebDriver driver, String OrganizationName, String TextToType) {
driver.findElement(By.id(OrganizationName)).sendKeys(TextToType);;
}
in your context this should probably work.
ncformPage1 skifootz = new ncformPage1();
skifootz.getOrgname(skifootz.driver, "OrganizationName");
skifootz.sendKeys("Rolling Stones");
public class ncformPage1 {
private String orgName;
public WebDriver driver = new ChromeDriver(); // I'm assuming this part.
public ncformPage1(String on) {
orgName = on;
}
public WebElement getOrgname(WebDriver driver, String OrganizationName) {
return driver.findElement(By.id(OrganizationName));
}
}

Get index of LinkToAction on table - WD Java

I have a data table and I want to show detail when clicking each row on it. But the index always returns 0.
int index= wdContext.getCurrentElement().index();
wdComponentAPI.getMessageManager().reportSuccess("test "+ index);
Please help me review and give your thoughts.

You have several options here. First option:
wdContext.node<YourNode>.getLeadSelection().index();
Pay attention to get lead selection of your node but not of the root context. Also context mapping should be properly defined for this to work.
Second option is to use wdDoModifyView event:
wdDoModifyView(...)
{
if (firstTime)
{
IWDLinkToAction link = (IWDLinkToAction) view.getElement("LinkID");
link.mappingOfOnAction().addSourceMapping("nodeElement", "rowElement");
}
}
Here we map built-in parameter nodeElement to our target rowElemen parameter which would be used in LinkToAction handler.
void onActionLinkClicked(..., I<DataSourceNode>Element rowElement)
{
/* do whatever with row element */
}

Oracle ADF When Selecting Multiple Rows, RowSetIterator Does Not Populate on First Method Invocation

Uncertain how best to word the title, but here's the gist.
The goal is to retrieve all selected rows of a table and manipulate them. The problem I'm bumping into is that the RowSetIterator doesn't get populated the first time the method within my backing bean is invoked. It does get populated when invoked a second time.
How do I go about getting it to work properly on the first invocation?
Doubtless I'm not being perfectly clear, please let me know if you require any additional information. Here's a snippet of the bean method:
public String deleteSelectedQueries()
{
JSFUtils.addInformationMessage("Delete");
RowKeySet selectedQueries =
getSavedQueriesByUserTable().getSelectedRowKeys();
Iterator selectedQueriesIter = selectedQueries.iterator();
DCBindingContainer bindings =
(DCBindingContainer) BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding savedQueriesByUserIter =
bindings.findIteratorBinding("SavedQueriesByUserROVOIterator");
RowSetIterator savedQueriesByUserRowSetIterator =
savedQueriesByUserIter.getRowSetIterator();
while (selectedQueriesIter.hasNext())
{
Key key = (Key) ((List) selectedQueriesIter.next()).get(0);
Row currentRow = savedQueriesByUserRowSetIterator.getRow(key);
System.out.println(currentRow.getAttribute("QueryName"));
}
return null;
}
}
Any ideas?
Thanks!

This code looks good to me.
The problem may come from <af:table> tag, make sure you have these tags removed:
selectedRowKeys="#{bindings.SavedQueriesByUserROVO.collectionModel.selectedRow}"
selectionListener="#{bindings.SavedQueriesByUserROVO.collectionModel.makeCurrent}"

Duplicate Check in Java

I am writing a small integration piece to to retrive the testcases from TestCase Management tool in java, in which i have the following scenarios:-
1) I have testcase which is “failed”, that time I am checking whether there is any defect which is already exists in the Defect management tool for the failed testcase using the testcase name , because the testcase name and the defect name are same in our case.
If not I am logging the new defect. This is fine.
2) In another case, I have testcase which is “Passed” at the first time, for that also I am checking the whether there are any duplicate defect is present in the Defect management tool , eventhough I am not going to log any defect.
This I am doing because, I don’t know whether the testcase is “Pass” or “Fail” in the first attempt or not. Hence I am doing this mandatory check , to see whether the duplicate defect exists or not for both “pass” and “fail” testcase.
I know that it is wrong to check the duplicate existence of the defect for the “pass” testcase. But there is no option I have. Is there any way we can ignore calling duplicate existence of the defect method if the testcase is “passed”?
I want your guys opinion on this.
This is the code which i have:-
private int NOT_TESTED = 0;
private int PASSED_1 = 0;
private int PASSED_2 = 0;
private int FAILED =0;
private String testStatus = "pass"; // will be fetched dynamically
private void execute(){
if(testStatus.equalsIgnoreCase("fail")){
//FAILED--;
FAILED = FAILED + 1;
System.out.println("the failed value is:"+FAILED);
}else if(testStatus.equalsIgnoreCase("pass")){// first attempt
PASSED_1 = PASSED_1 + 1;
System.out.println("the Passed_1 value is:"+PASSED_1);
if(PASSED_1 == 1){
System.out.println("Passed in the first attempt, hence no need to create a defect");
}
}else if(testStatus.equalsIgnoreCase("pass") && FAILED ==1){// second attempt
PASSED_2 = PASSED_2+1;
System.out.println("the Passed_2 value is:"+PASSED_2);
if(PASSED_2 ==1){
System.out.println("Passed in the second attempt, create a defect");
// logic to create a new defect
}
}else {
System.out.println("The test not tested");
}
}
This code is not working as it always go to the first pass attempt state, hence please do provide a solution to find if the testcase is passed in the second attempt (FAIL->PASS) so that we can take appropriate action on this.
Thanks in advance.

if the condition (testStatus.equalsIgnoreCase("pass") && FAILED ==1) is true, it means that the condition before it is also true:
if(testStatus.equalsIgnoreCase("pass"))
Since you used if-else, it will go into the first condition and then skip the rest.
Switching between those two will give you the desired result I think.
