What this one does?
I tried http://kuba.zilp.pl/?id=1, and don't understand the statement " ADFUtils.executeOperation("downloadingPageDef", "Execute");". What this one does?
Thanks in advance!, I am using jdeveloper 10g.

Thanks in advance!, I am using jdeveloper 10g.
ADFUtils is a utility helper class for usage in the ViewController. I am not familiar with the specific 10g version of executeOperation() method but it seems to be used to execute a method binding. In this case the method binding is called Execute and is bound in the downloadingPageDef page definition file.
Searching the forum will yield these results:

so, ver instance has been presented to the setDefaultHostnameVerifier . fine....but who is calling the methods verify() which is described in the implemented Annoynymous interface HostnameVerifier .
who is calling that overridden method verify() ?
similarly, who is calling getAcceptedIssuers() method?
I DONT see any invocation of these overridden methods .
are these methods are FRAUD and BUGGY...and are not needed in this code....are they redundant ?
OR are these methods are invoked by the HttpsURLConnection internally somehow....

Where/how can i find out what this is doing
I know this old but not concerned with that, just what is it doing, this is java script in an .asp that loads
a flash application, I'm most concerned/interested
why it references a clsid?
what is the code base all about? (is this embedding code in the browser? it does the embed everytime the app is loaded?)
what is the PLUGINSPAGE?
how does all this affect the opertion of the flash apps that run after this initializtion?
this is kinda/somewhat/ normal for anytime /anyone running a flash app?
It seems there's a lot going here, if too much to answer please just point me somewhere where i can RTFM, but
please make it a good RTFM not a FWOT!!!

hey this is part of some parser code from an earlier java forum post

i modified the code slightly to work with my program which involves its use in an applet and to solve logical equations. However i'm still uncertain as to what certain sections of the code are doing
i know that this code evaluates the variables within the given equation, begins a for loop that does not exit until i = codeSize which is the length of the given String. However i'm not so certain as to how it achieves this. I'd like to know

if (code[i] >= 0)
stack[top++] = constants[code];

int y = stack[--top];
int x = stack[--top];
int ans = (int)Double.NaN;
switch (code[i])
case PLUS: ans = x | y; break;
case MINUS: ans = x & y; break;
case TIMES: ans = x & y; break;
case DIVIDE: ans = x / y; break;

podgerWell this is a very basic interpreter. What this piece of code does is:
1) take an opcode from the code array, and retrieves the description for it from the constants array. This description is stored in the stack array.
stack[top++] = constants[code];
2) check what opcode it is
switch (code)
3) "execute" the opcode with simple java math operators.
case PLUS: ans = x | y; break;
case MINUS: ans = x & y; break;
case TIMES: ans = x & y; break;
case DIVIDE: ans = x / y; break;4) store the result of the opcode in the stack array, after the description of the opcode retrieved in step 1)
stack[top++] = ans;There is also some sort of error check in there: initially the result of the opcode is "NaN", (not a number). If the opcode passed to this code is not known, the result is not added to the stack according to this piece of code:
if (Double.isNaN(ans))
return ans; -
Q1.
boolean isInterface()
Determines if the specified Class object represents an interface type. what this method means ?
Look it is saying "....object represents an interface type.. But an interface can not refer objects unless it is implemented by some concrete class.
is there any polymorphism involved(i guess) ?
i mean like this ......
interface ABC
// blah
class CDE implements ABC
// defined everything here
ABC s = new CDE(); // it is legal
does this method relates to this ?
Am i right ? However code below is not comfortable.........
Q2:
Here is the code i stumbled................ It usues that method.
Description: Determining If a Class Object Represents a Class or Interface
Code:
Class cls = java.lang.String.class; // Line-1.....is it valid !!!!
boolean isClass = !cls.isInterface(); // true
cls = java.lang.Cloneable.class;
isClass = !cls.isInterface(); // falseLook at Line-1.................i dont see any heirchy down the String class in the API.....( java.lang.String.class .....is it valid ? yes that bold .class !! ) its a peculiar use of String class !!.
can anybody explain what is happening here. what reference who calls ?
Thank yougood explanation indeed.
Look ur comment
// By way of a string........why String ? why
do i hardcode
Class.forName("java.lang.String");......there
are lots of Classes in the API who extends Object
class.
Look
cls = java.lang.String.class // again u have
hardcoded String class !!!
It seems to me i need to hardcode always with
String class( right ? no other class can be
usued !!) to get the Class or Inteface type out of
object.No, you can do it for any class: Class c1 = List.class;
Class c2 = new List().getClass();
Class c3 = Class.forName("java.util.List"); All are legal, and you can do that with any class or interface, not just String.
So if you do something that gets a Class object--say the user enters a class name or interface name, and you pass that to Class.forName()--you can then call isInterface() to see if it's an interface.
String classname = getStringFromUser(); // assume user enters "java.util.Comparator"
Class klass = Class.forName(classname);
boolean isIxfc = klass.isInterface(); // true for java.util.Comparator -
Hi all,
Following are few code lines from MAM code :
// this is in common.inc"
<jsp:useBean id="helper"
class="com.sap.mbs.core.web.ViewHelper" scope="request"/>
String allOrderURL = helper.eventURL("onOrderList", "orderListType", "ALL_ORDERS");
helper.getApplicationURL()
Could anyone please tell what this eventURL ,getApplicationURL methods are for ?
I couldnt find any documentation that explains it.
Regards,
VipinHello Vipin.
Jo is rite.
The class is abstract but the class which is used to create the bean is the implementation class:
<b>DefaultViewHelper</b>
This is the implementation of the abstract class ViewHelper.
The ViewHelper is used to create URLs which are used to load a new page with our without submitting a form.
You can use eventURL to build an URL for a link you want to create (JO's example).
You can use submitEventURL in order to submit your form.
This method builds a call to a JavaScript method.
You can find this method in the file:
app-root/include/common.inc
function submitURL(url).
This function uses url as action for the submit.
So if you use something like this:
onClick="<%=helper.submitEventURL("onOK")%>"
all the form content is written to the context and the onOK method of the corresponding controller class is called. You can get the form content using the context in this controller method then.
When I started working with MAM I was also confused about the mbs.core Framework.
Read this maybe it helps:

Anyone know what this sign does?
Good morning all,
Just a quick question. Ive tried googling this and checking my books but after an hour of doing so I just thought Id ask. Why would one use th (+) in a query, especially when joining two tables?
I saw this:
SELECT inv.item, inv.price, recpt.recept
FROM inventory inv, receipts recpt
WHERE inv.item(+) = recpt.item;
But dont know why you need that plus sign. Whats its purpose?Spot the difference:

What this function does: AIB3_EVALUATE_ODS_ASSIGN in PS/IM?
Dear all,
I'm investigating for the possible cause of data lost in transit in PS/IM area. The suspect currently is an update rule involving a function AIB3_EVALUATE_ODS_ASSIGN, as based on its E_SUBRC output value a record is skipped or not. Though I'm working with Z-objects now, this turns to be a part of Business Content as well.
Does anyone has an idea what is the logic of that function? SAP doesn't provide any documentation on that, so the only option I have at the moment is to play with that blackbox...
Cheers!
/RBI'm not worried about race conditions, as evaluation of the expression takes place as the last thing before the new execution is started. It must either be done just before the SequenceCall, or as the first thing in the Setup group of the subsequence.
It's fragile to modify the expression at runtime to mimic a different context (by replacing stuff like "Locals." with "RunState.Caller.Locals." for instance, if they were in the same callstack), since such string replacement could never be exhaustive. What about "Step."? What about constructs like ("L" & "ocals.")? I could never identify them all.
I could split the expression up in two, like this (evaluated in the subsequence):
Evaluate("Locals." + Locals.TargetName) = Evaluate("RunState.Caller.Locals.SourceName")
The above works if Locals.SourceName was in the caller context, but my problem is a bit more complex than that; I need the right hand side to evaluate any expression string, and I need to supply a context to do it within. It's too fragile to string-replace "Locals." with "RunState.Caller.Locals." etc., as the expression might contain "Parameters.", "FileGlobals.", or much more complex access patterns from the caller context.
One way would be to make a new expression object and use Expression.Evaluate(context,evaloptions) on that in the subsequence, with context passed from the caller, but how do I make and pass an expression object to the sequence in which to set the TargetName local variable? It has something to do with Engine.NewExpression, but where do I store this expression object in the caller? And how do I set its Text property to "Locals.SourceName" (in this particular example, but remember it could be any expression)? And finally how do I pass this expression object to the subsequence via a parameter (what type should the parameter be)?

[/code]Your first piece of code does not work, because a create table statement cannot be issued using a ref cursor like that. When executed with the "execute immediate" command, it works. Then, the refcursor is only a "select * from report_tbl".
What it does, is dynamically dropping and creating a table report_tbl and filling it with the results of a horribly inefficient pivot query. If the report_tbl has no other purpose after running this procedure, then I'd suggest to not drop and create tables dynamically like that. In the second variant of test_transpose, you can see how you can do that.
