Getting "Method" objects
hi, i'm trying to encapulate a method in an Object and utilize the methods in the Method Class.
eg:
void AMethod() {
I want to get associated object for AMethod() and call methods in the Method Class with it. ie:
object = AMethod.invoke();
thanks

Getting Method objects without reflection
This is a shameless plug to try to get votes for a recent bug I've filed:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6356762
For a long time, it's bothered me that there is no way other than reflection to obtain Method and Field objects to identify components of classes. It should be possible to write something like MyClass.class.nameOfMyField to obtain the FIeld object directly. With the current reflection-only method, one has to obtain these by looking up their String names. So:
-there's no way for the compiler to detect syntax errors at compile time
-no real way to obfuscate this code
-debugging is more difficult because you are working indirectly through strings
-it's inelegant to use Strings to perform at runtime what the compiler should be able to do at compile time
One of the most immediate uses for this could be with classes conforming to the Beans pattern. Instead of specifying String names directly when firing property change events (whilch always risks a typo cauing a hard to trace error), you could obtain the coresponding Field object and call getName() on it.
If something like this could be provided in Mustang, I would be in seventh heaven. Please vote for the bug, or let me know what you think about this.I would definately have usage of that. I've always loved function pointers in C, and jump tables in assembler.

Problem extending standard ViewReceiptsSearchVO view object with logic on get method
Hi All,
EBS 12.1.3
Database 11.2.0.3
I am trying to extend the 3 VOs related to ViewReceiptsSearch. I extended a seeded ViewReceiptsSearchVO view object. I haven't made any changes yet, no columns added, nothing altered. When I run this substitution, the "Received" column is null. This column in the view used for the view object only selects NULL and uses the getter method for the attribute to populate the value. The generated extension getter calls getAttributeInternal and skips the logic in the standard getter and the substituted view object is displaying the null in the screen. The below discussion explains the problem very well except that the original posted had the issue in 11.5.10.2. I am having this issue with 12.1.3.
Problem extending standard view object with logic on get method
The 3 VOs that I am having the problem are:
ViewReceiptsSearchVO
ViewReceiptsSearchReqVO
ViewReceiptsSearchSupplierVO
What do I need to do to get the "Received" column populated? Please let me know any additional information you want to troubleshoot the issue.
Thanks.Hi,
Can you Please Share Extended ViewReceiptsSearchVO.xml and .jpx File?
Thanks,

How to get caller object reference from a method
Hi,
I am working a already existing Java Swing project, now I got a problem, in a method I need to get the caller object reference otherwise, I can't succeed this operation. So please tell me a way how to get the caller object reference from a method. that method would be static or regular method anything will do for me.

Actually my doubt is, I have a method "addition" method, which is using by many classes so my requirement is in the addition method I want to write a code snippet which will identify and get the the caller object. Actually I tried Reflection.getcallerclass but there I am getting "CLASS" object not the actual object reference, but I want object reference.
Actually we have a huge project which is writen plain JAVA, so in this project the authors written the Database connection package for single database transaction. so now we are using this project source code for JSF application in this web application the DB package has serve based on the dynamic db connection parameters, so if we want to change this package fully means need to solve the dependency problem in hundreds of classes, so my point is if I can access the caller object in the DB package when ever it gets called by any class from any where of the project. So actually I liked Reflection.getcallerclass, the way of implementation perfectly works for me but it is not giving caller object reference, if something gives the caller object then I can get the DB connection parameters then there is no need to pass the parameters in the hierarchy.You can add a parameter (of type Object) to your addition() method
and everywhere you call the addition() method also pass this (which from the POW of the addition() method will be a reference to the calling class instance).
There may be alternative solutions
but none that require less effort. -
Can't get my class's getter method to work properly.
Hello, I am new to Java programming, although I come from C and C++. This is my first post. I am working on a basic Library application that can Checkout and Return books. Eventually I would like to add the ability to read from and write to an XML file containing data for every book.
My problem right now is that I cannot get my getter method within my Book class to work properly. When I call getData() from within main, and pass the appropriate arguments, instead of filling the variables with that object's data, it leaves them blank! Please help me.
Here is my method within the Book class, the person and id_num are private.
/* Gets general Book Instance Data and fills parameters with it */
public void getData(String n, int num, String c, String d)
n = this.person;
num = this.id_num;
c = this.checkout_date_string;
d = this.due_date_string;
}Here is how I am attempting to use it in main:
String name = "";
int number = 0;
String checkout = "";
String due = "";
Book book1;
/*Sets person = John Smith and id_num = 10763*/
book1 = new Book("John Smith", 10763);
/*Gets Checkout (todays) date and sets a due date in 2 weeks*/
book1.Checkout();
book1.getData(name, number, checkout, due);
System.out.println("Book1:\n Checkout Date: " + checkout +
"\n Due Date: " + due + "\n Is it late: " + book1.isLate() +
"\n Person who checked it out: " + name + "\n ID number: " + number +
"\n ");Then, Here is the Output:
Book1:
Checkout Date:
Due Date:
Is it late: false
Person who checked it out:
ID number: 0

Well I went ahead and made separate methods to return each value. I suppose that will work just as well, especially since now I don't have to declare a bunch of strings and int's to hold the data and pass to the method.
>
Well this would never work anyway
public void getData(String n, int num, String c, String d)None of those can be changed within the method. Strings are immutable and 'int' is passed by value. Each of those parameters will have the same value after the method exits as they did before it was called.
Your book class should be using 'setters' to set the value of its instance variables. -
Problem in getting an object in JSP page.
Hi experts,
I am forming a javabean object in the controller(servlet) and passing the object to a JSP page by setting that object as an attribute. But in that jsp page, when i compile, its not able to locate the class. At the beginning itself while typecasting the attribute as that bean object, i get an error. All the servlet, bean files are in the default package only.
This is how i used..
<%
String m = (String) request.getAttribute("mode");
//My bean object below.
adjuster_bean res=(adjuster_bean)request.getAttribute("data");
%>
And i am using like, calling the bean object's get method to set values of the text boxes in the JSP page. I need help please....Vigsen wrote:

<%@ page import="java.util.*, yourpackage.YourBeanClass" %> Secondly, I see standards not followed in your code...
a) Firstly, as someone else pointed out in this same post. Avoid as much as possible using java scriplets in JSPs. Instead try use JSTL and EL expressions.
b) A java class name should always start with capital letter for every word in the class name and with no underscores. Your bean class name (adjuster_bean) should be changed to something like AdjusterBean
If you want to become a good Java programmer then standards are essential. But, again, it is totally up to you to follow. -

**URGENT** No getter method for property searchText of bean org.apache.stru
I'm implementing a query page as described in the HowTo ADF_ComplexMasterDetail.zip
When running the query page, I'm receiving the error:
javax.servlet.jsp.JspException: No getter method for property searchText of bean org.apache.struts.taglib.html.BEAN
I have my searchEmployees writen and 'exposed' (at least I can see it in the Data palette). But seems like something is missing, and can't find this searchText beam property specified in the html:text tag.
Can someone help in this one?
Here is the Help description inside the HowTo example:
Section 3
queryEmployees
queryEmployeesInDept provides an interface for entering a simple search criteria for querying a list of
employees. This does not use the Find mode Query By Example functionality that the other query screens
use, but rather presents a much simpler search interface. The actual search is carried out using a
function
searchEmployees that the underlying view object exposes. (See the EmployeesView view object in the
model project)
1. Drop a new Data Page onto the page flow diagram call it queryEmployees
2. In the page flow diagram, drag the searchEmployees operation from the AllEmployeesView
collection in the Data Control Palette and drop it on top of the new Data Page. This will cause the
framework to run a search whenever the page is called.
3. In the Structure pane, locate the queryEmployees node and expand it, select the child node
paramNames[0], and change it's value attribute to ${param.searchText}. This will pass the URL
parameter searchText on to the business method to qualify the query.
4. Drill down into the page and expand the Data Control Palette to select the AllEmployeesView
collection. Set the Drag and Drop as: list to Read-OnlyTable. Then drag the collection onto the page.
This will create a tabular containing the query results.
5. Select the Struts HTML component palette and drag a Form onto the page above the output table. Set
the handling action to this Data Page (queryEmployees.do)
6. Drag a text field from the component palette inside of this new form. Set the property attribute of
the
<html:text> tag to searchText (the same value you used in the paramNames[0] for the Data Page)
7. Create a new submit button in the form to submit the search. Set the property attribute of the button
to
event_search.
8. Finally we need to subclass the data page to prevent the search action from being fired when it is not
appropriate for the page ( for instance when we first display it). To do this we need to Go to Code on
the Data Page's context menu, and override the invokeCustomMethod() method:
* We only want to invoke the custom method i.e. the call to change
* the Where clause on the collection, if the Action has been called with
* a search event on the page with a search term supplied.
* If the user got here via a link or another event, we bypass the model call
* unless a URL parameter event=search is supplied, in which
* case the method will also be called.
protected void invokeCustomMethod(DataActionContext actionContext)
List events = actionContext.getEvents();
// If the event is "search" do the custom event call
if ((events != null) && (events.contains("search")))
String searchTerm = (String)((DynaActionForm)actionContext.getActionForm())
Get("searchText");
if (searchTerm != null)
super.invokeCustomMethod(actionContext);

Getting ServeltContext object in different ways
If we can get ServletContext object in our servlet using getServletContext() then what is the need for getting it using the ServletConfig object i.e by
using config.getServletContext() where config refers to the ServletConfig object.
Are these methods there just for convinience ?Just read the API documentation: http://java.sun.com/products/servlet/2.5/docs/servlet-2_5-mr2/javax/servlet/GenericServlet.html#getServletContext()

No your aren't.
You are sending the data in the class.
That is what serialization does. (And actually not all data can be sent either.)
When i get the object on server, i am able to print all its fields and methods... But i have one problem. I want to invoke a simple static method that just prints "hello".. The method on client that i am trying to invoke is....You probably either need stop attempting that or re-architect the solution.
It is possible to send a class (not data) to another computer and that computer runs it. That is how applets work.
But for that to work you must send the class. And deal with how the VM loads and unloads classes (not data) as well. -
Value Change event is not working. Html Panel Grid get method is not called
Hi,
I'm creating components dynamically.
I have a dropdown. Based on the selection of dropdown, the panel grid is getting called.
First time the panel grid getmethod is getting called. But when i change the value of drop down, panel grid get method is not getting called and its not rendering.

</t:selectOneMenu>

}Hi,
I'm having the exact same problem, and it's freaking me out!!! The setGridPanel method is always called but not the getGridPanel. This one is only called the first time the page is rendered, and when I change a drodpdownlist it never gets the gridPanel again! I'm using an HtmlPanelGrid. Anyone can help please?
Thanks in advance,

Bill b = new Bill();
entityManager.persist(b);
entityManager.flush();
entityManager.refresh(b); // Here where the exception is thrown
int id = b.getId();When I try without refresh, it still get no id -
