How to access last object in a Collection.

Hello. I'm trying to figure out how to access the last element in a collection. This is how I have it coded now:
Collection coll = someMethodThatReturnsACollectionOfMyTypes( );
Iterator It = coll.iterator( );
MyType myType = null;
while ( It.hasNext( ) )
myType = ( MyType) It.next( );
At this point myType should reference the object I'm interested in, but there has to be an easier way. Any suggestions would be greatly appreciated.

Containers either are or aren't expected to support random access, depending on the container. For those containers that do support it, like ArrayList, you can do the following:
public Object getLast(AbstractList a) {
if (0==a.size()) return null;
return a.get(a.size()-1);
}

How to access Business Objects Explorer?

I am new to Business Objects and would like to know how to access Business Objects Explorer from my local system. I have Business Objects XI 3.1 installed on my system.
I would like to know if BO explorer requires a separate installation package? If yes, how can I acquire it?
If No, what are the steps to integrate the BO Server with the BO explorer?

How to access an object in a bean

I am looking for a way to access an object in a bean and make available to the page.
for example if i have a Bean called User and it contains an attribute Called Company as an attribute in User. Now I have User.getCompany(). and I can do this
<%User user = request.getUser();
Company company = user.getCompany();
request.setAttribute("comp", company); %>
how do I do this with useBean ?

<%User user = request.getUser();

how do I do this with useBean ?You can access a JavaBean Object property of another JavaBean inside the JSP with the use of EL (Expression Language)
So if you are using JSP 2.0 or higher try this:
<jsp:useBean id="user" class="your.package.User" scope="request"/>
${user.company.id}I tested the above and it works.
Note that you need to set the Company object in the User object before trying to access it inside the JSP.
You can also set it in the JSP if you want, (before trying to access it), but its cleaner to do it in a Servlet.
Both User and Company must follow JavaBeans notation.
So in the above case the User object is something like this:
package your.package;
public class User{
   private Customer customer;
   public User(){}
   public Customer getCustomer(){
      return customer;
   public void setCustomer(Customer customer){
     this.customer = customer;
}And your Customer JavaBean is something like this:
package your.package;
public class Customer{
   private int id;
   public Customer(){}
   public int getId(){
     return this.id;
   public void setId(int id){
     this.id = id;
}

ListCellFactory - how to access an object's data associated with list cell?

I am new to javafx and building a sample app to learn the basics. The app has a list view control and used listcellfactory to create listcells. Each list cell is composed of few labels and image. I populated list view with listViewItems function, where in it sends object[]; I have my own object with data that needs to be populated in the list cell. I have hard coded the object[] and that size is reflected in list view items size. However, I am not able to populate the object data in individual labels.
In the following code, I can only get the string representation of the object and I am unable to figure out how to individually access the object's data. Please help me with this.
function listCellFactory(): javafx.scene.control.ListCell {
var listCell: javafx.scene.control.ListCell;
def offerLbl: javafx.scene.control.Label = javafx.scene.control.Label {
text: bind "{listCell.item}"
def descriptionLbl: javafx.scene.control.Label = javafx.scene.control.Label {
text: bind "{listCell.item}"
def friendLbl: javafx.scene.control.Label = javafx.scene.control.Label {
text: bind "{listCell.item}"
def offerImgView: javafx.scene.image.ImageView = javafx.scene.image.ImageView {
image: imagetrial
fitWidth: 300.0
fitHeight: 250.0
def offerVerticalBox: javafx.scene.layout.VBox = javafx.scene.layout.VBox {
content: [ offerLbl, descriptionLbl, friendLbl, offerImgView, ]
spacing: 6.0
listCell = javafx.scene.control.ListCell {
node: offerVerticalBox
return listCell
}

If I understand you question, it should be (listCell.data as YourClassName)

How to pass Custom object embedded in Collection

Hi,
I'm building an J2EE application(Weblogic 7.0) with swing Client. Our requirement
is to add custom objects in a Collection and return it to Client thru web service.
I dont know how to write build.xml so that ant utility created its own parser
file for the cutom object. We may have lots of custom objects . These objects
are being returned by a generic response object . I mean a Collection may conatin
different custom objects depending upon context. This Collection is embedded in
the generic response object. Can anybode help me to write a buil.xml for this.
Please suggest a best solution.
thanks
Jobinesh

Contd.......I forgot to mention one thing. We are supposed to use StatelessSessionBean
as front controller. In this context we can use the ant task for converting this
front controller to web service.
Pls help me....

How to access Captivate Objects From Widget

Using the widget factory, is there a way to access a specific property such as a button or textbox in a captivate movie from an widget?
The button in captviate does have an instance name called button_mc. In my widget, I do have
myRoot = MovieClip(root);
mainMov = MovieClip(myRoot.parent.root);
Also, how can you get the slide properties such as total frames?
Can't seem to find out how or I am just missing something
Thanks

Hi Ukie,
Here's an article on how to access objects on the Captivate slide with WidgetFactory: http://www.infosemantics.com.au/widgetking/2010/10/slip-sliding-away/
In short, pass in the instance name of the button into the getSlideObjectByName() method:
var myButton:Sprite = getSlideObjectByName("button_mc");
Also, WidgetFactory has a property widgetSlide wich gives you access to the slide that the Captivate Author placed the widget on. This is a MovieClip, so if you wanted to read its total frames, you'd write:
widgetSlide.totalFrames;
Hope that answers your questions.

How to access Business object type attribute from a method/function modul ?

Hello,
i have created a business object type object along with attributes and methods. Now inside the method i want to access the attributes. inside the method i am writing:
data a type XXX.
a = me->attribute
this is creating a compilation error.
Now the method is defined as a function module in some package, so can anyone inform me how to access object attributes from the function module ?
pointes are awarded
Regards

Hello,
thanks for your answer, but this too did not work, "=>" is for static attributes and the attributes i have are not static. Moreover, i tried it but it gave the same error :
the abap error was when i was checking the code is :
the type me=>documenttype is unknown
as you know in SWO1 i created an object and when i create a method you link it to a function module and this is where you have the implementation of the method, so from this method how can i access the attributes on the main object that i created in SWO1

How to access ServletContext object of a webapp on remote server?

Hi!
I have a webapp, runs on tomcat, loads information from local db server, keeps them in servlet context, and publish these datas to web via jsp pages.
I make run the same webapp on different location, different webserver and db server with different datas.
Is it possible to link both ServletContext to each other, or access one from the another?
What is the right solution, if I want to access all stored Objects of these independent webapplications, summarize and show them in one browser page, in one jsp?
sorry for my poor english
and thanks for any help,
kind regards,
henpanta

It is not possible to access another servletcontext glueless using HTTP or any transfer protocol. Would be a potential security hole too. If you want to let communicate 2 webapps on different servers with each other, consider webservices.

How to access servlet objects from OA page controller class

Hi everybody!
I need to put some value into servlet attribute in OA page controller class to read it from ordinary servlet later.
How can i do it? Is it possible to get HttpServletRequest and HttpServletResponse objects from page controller?
Thank you.

I have a servlet which receives uploaded files with special attributes (something like tags for file) using POST request.
This attributes created when user open page in standard OAF page via page controller.
On client side I have an applet which uploads user selected file to my servlet and passes this file attributes.
Now this attributes passes as plain text. I want to encrypt this attributes to hide attribute details from user. To do this I need to share some information between OAF page and my servlet.
I know that OAF supports URL encryption, but to decrypt it I should use standard pageContext object.
But in ordinary servlet I can't use it.
