Unsure as to operation of intersects method in Shape

I am writing a program in which i need to check whether or not 2-D objects (primarily squares and circles) are touching each other. The documentation for intersects says that it tests whether the interiors of the shapes intersect each other, however my question is whether or not intersects will return true if the interiors are not touching but if the lines that make up the shape are. For example this would be if one edge of R1 is coincident with one edge of R2 or if a vertex of R1 is on an edge of R2 but the interiors do not intersect.

It would probably be too tough to just go and run a test for yourself. It's a good thing you've come here to get us to run the test for you.

What's the different between an Operation and a Method?

Hello,
I am wondering about the difference between operations and methods.
For example, if I am listing the operations of a stack, I would say:
1) Construct and Destroy
2) Push
3) Pop
4) Top
5) Empty
6) Clear
...but are some of these methods just method and not operations?
Again, for example if I am listing the operations for a Queue, I would say:
1) Enqueue
2) Dequeue
3) Head
4) Empty
5) Clear
...but as some of these methods are not unique (i.e. 4, 5 & 6 are the same for queue as it is for stack) then are some of these methods just methods and not operations?
Yours confused,
Wood

Ahem: "If formally, what are their definitions?"
Feel free to consult the JLS: [http://java.sun.com/docs/books/jls/third_edition/html/j3TOC.html]
There is no definition or use of "operation" as you seem to be plying it, in the JLS. Note that constructors are not methods, according to the JLS definition of method.
On the other hand, if asked a question on an exam, I wouldn't stick to wooden definitions. I would use commonsense.

The dot operator and a method called 'cons'?

I'm trying to write a static method that takes a list of things (array or List objects).
It returns another list based on the first but changed by some rule.
I am told that I have:
non-static methods - head, tail, cons, isEmpty
a static method - empty (creates a new list)
I have to assume (was not told) that:
'head' returns the object at the head of our list
'tail' returns the next object from the one we are looking at
'isEmpty' returns a boolean if nothing there.
and lastly:
'cons' which meant nothing to me but I have been advised that it probably does something like concatonates or adds to the end of.
1. Is this name (cons) in popular use & what does a method with that name usually do?
2. Assuming I'm right and I want to step through adding the elements in turn.
Which do you think would be the right way to add/append/concatonate (or whatever) the current element to my newList?
newList = newList.cons(lst.head()); or
newList = lst.head().cons(newList);('lst' being the particular list we're looking at)
Is there something else I should have written?
For some reason I find this very confusing!

Yes, something like that :)
Now let's see what we have to do...
1. if the list is empty we can just return it.
2. if the head of the list is the same as 'target' and n is 0 (or 1), take the tail of the list, add 'alternate' to it, and return it. I.e. return lst.tail().cons(alternate); (syntax depends on what arguments your cons takes, I guess)
3. if the head of the list matches again but n > 0 (or 1), decrement n by one and recurse with the tail, add head to the result; return changeNth(lst.tail(), ...., n-1).cons(lst.head())
4. else it is safe to recurse with the tail; return changeNth(lst.tail(), .....).cons(lst.head())
The code with Lots of Idiotic Silly Parentheses would look a bit like(defun changeNth (lst target alternate n)
(cond
    ((null lst) lst)
    ((equal target (first lst))
      (if (= n 0)
        (cons alternate (rest lst))
        (cons (first lst)
          (changeNth (rest lst) target alternate (- n 1)))))
    (t (cons (first lst) (changeNth (rest lst) target alternate n)))))

Question about operations allowed in methods of stateless and stateful bean

Hello,
Can anyone tell me why ejbRemove and ejbCreate are allowed entreprise beans and resource manager access in stateful session beans and not in stateless session beans?
Thanks in advance,
Julien Martin.

Salut Julien,
Can anyone tell me why ejbRemove and ejbCreate are
allowed entreprise beans and resource manager access
in stateful session beans and not in stateless session
beans?I'm not sure I fully understand your question, but here is some information that may answer it.
The user is the one who creates and removes a stateful session bean. The container is the one who creates and removes a stateless session bean. So the user can pass any parameters to the create of a SFSB because he theorically knows what to pass. The container doesn't, and doesn't want to. It just wants to create SLSB to pool them, but it doesn't pool SFSB.
Maybe it doesn't answer your question. Can you reformulate?

Saving PDF from AI causes TIF images to be 'intersected' by vector shape behind it

Hi,
I am encountering this issue frequently and would appreciate any insight...
When I have a design made up of both embedded TIF Images and vector shapes which overlap, the shape of the vector beneath 'cuts' or intersects the image laid on top and produces a white area there.
It is seen in the full color PDF's I send to the printers at the local newspaper. The PDF is saved at 180dpi. The 'save illustrator editing capabilities' makes no difference whether it's checked on or not. It does not occur in 300 dpi PDF's Saved from AI.
The problem is the printers save all artwork to 180dpi PDF's no matter what format I send.
Can this be avoided by doing something on my side? or has anyone else had this before?
Thanks,
TJ

How to allow multiple output parameters in a user-defined service operation???

I have creating a self-defined service operation “LDAPAddUser” to connect to LDAP server to create user accounts. I want to get 2 output parameters after executing the operation. One is the result (Boolean data type) and one is the error message (String data type). However, since Java only support one return value in a method, it seems that only one output parameter can be returned. May I have the suggestion so that multiple parameters can be supported in this case? Here is the extracted code
In Java program,
public Boolean addUser(String url, String aName)
In file "component.xml",
     <operation name="addUser" method="addUser" orchestrateable="true" anonymous-access="true">
<hint>Add a new user</hint>
     <input-parameter name="url" type="java.lang.String" required="true" title="LDAP URL">
     </input-parameter>
          <input-parameter name="aName" type="java.lang.String" required="true" title="Admin Login Name">
     </input-parameter>
          <output-parameter name="Result" title="Result" type="java.lang.Boolean">
          </output-parameter>
Besides the boolean return value, I want to get another return value (string data type). Any suggestion ?

I've returned multiple values to LiveCycle by using a complex object as an intermediatory.
For example if I need to return two strings (firstName and lastName), I'll first build a single class (name) with two string attributes (private String firstName; private String LastName) and add getters and setters to my "name" class for each. My service class method will return an object of type "name".
for example public name mymethod(String GUID, String username, String password).......
Then in the component.xml you can return the two strings as long as you use the binding type "Bean":
<output-parameter name="firstName" title="First Name" binding-type="Bean" property="firstName">
                    </output-parameter>
<output-parameter name="lastName" title="Last Name" binding-type="Bean" property="lastName">
                     </output-parameter>

JMS-send operation not working in a SessionBean [OC4J10.1.3.1.0-standalone]

Salut,
i am envisaged with a nasty problem calling a message-send operation from
a method (transaction-type="required") inside a session bean (transaction-type="container").
This problem occured in OC4J 10.1.3.1 and may fail also in 10.1.3.0. The same
code run under OC4J 10.1.2.x without any problems.
The adressed JMS type is a OEMS JMS and fails to work regardless if the JMS ressource
is using a file-persistence or is running in-memory. Anyway the factory is a
jms/XAQueueConnectionFactory, so the created queue must support XA transactions.
Another test with an advanced-queue JMS provider succeeded.
As a consequence of this, i believe that the OEMS provider shall cause the problem.
The original code is quite unspectaculary:
* The non-surprising thing is, that the QueueConnectionFactory
* is a XAQueueConnectionFactory.
QueueConnectionFactory qcf = (QueueConnectionFactory) (jndiContext.lookup(MY_QFAC));
Queue q = (Queue) (new InitialContext().lookup(MY_QUE));
c = qcf.createQueueConnection() ;
QueueSession s = c.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
[... create a message ]
QueueSender qs = s.createSender(q)
qs.send(m);
qs.close()
s.close();
c.close()
The funny thing is, that the queue-session behaves as it is working outside
of a transaction context. Inside the JMX-Console you will notice the
arrival of a message and ... a cancellation of it. This would not surprise
me, if this code sequence would have been called outside of
a Session bean, cause the absence of a queue-session.commit does not
fix the send message in the jms ressource.
As a matter of fact the code is executed inside a Session bean and
the connection.createQueueSession will notice this and forget both
given parameters, and let the covering transaction take over of the
JMS ressource. But this does not happen (completly).
The acknowledge-mode has been modified (SESSION_TRANSACTED)
but the code still does not work!
After i recognized that the enlist-ment did not work, i
decided to enfore the use of XA transaction by using the
XA classes and methods of JMS.
I startet to cast the jndi-references and:
XAQueueConnectionFactory qcf = (XAQueueConnectionFactory) (jndiContext.lookup(MY_QFAC));
Queue q = (Queue) (new InitialContext().lookup(MY_QUE));
XAQueueConnection c = qcf.createXAQueueConnection() ;
XAQueueSession s = c.createXAQueueSession();
[... create a message ]
QueueSender qs = s.createSender(q)
qs.send(m);
qs.close()
s.close();
c.close()
The funny thing is ... the code worked without any problem until
the send operation, where i received an JMSException, containing
the text:
Oc4jJMS.Session.hpcl057.4e9c06e4:1112674930d:-7fff.41,true,SESSION_TRANSACTED]: An attempt was made to perform work in a XA-backed session without being enlisted. Either the session must be enlisted (using the JMS Connector or JMS Adapter) to participate in the global transaction, or a non-XA connection and a non-XA session should be used to not participate in the global transaction.
How bizarre, i thought the enlistment has been taken place by invoking
the c.createXAQueueSession or c.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
How bizarre how bizarre
any clues ????

OC4J JMS was changed to not auto-enlist in XA transactions.
In releases prior to 10.1.3 XA usage was not actually supported. (It did not meet all of the XA requirements when used with OC4J.)
Auto-enlisting by the JMS provider was also a spec violation, which was causing trouble for people who needed to do out-of-transaction work and had no way to do it.
In 10.1.3 XA usage is fully supported, but only when you use the JMS Connector. You can find the JMS Connector ("Oracle's Generic JMS Resource Adapter") demos here:
http://www.oracle.com/technology/tech/java/oc4j/1013/how_to/index.html#JMS
The JMS Connector is documented in the OC4J Services Guide, OEMS/JMS chapter.

Oracle ADF - Commit operation issue.

Hi,
I am new to Oracle ADF. I am using Oracle jDeveloper 11.1.1.4.0
and facing problem when I try to save a new record from within application.
I have called a action on commit button and used auto generated code, here is the it -
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("Commit");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
I read that after execute statement framework calls doDML(int operation, TransactionEvent e) method in EOImpl and there we do insert/update/delete...etc,
But when I debug my application it doesn't. Please correct me if I am wrong.
Unable to understand what exactly the problem is?
Appreciate your help.
Thanks in advance.
Madhav.

Hi,
Yes, I do have a break point in doDML() of EOImpl.java
Also I have another break point in bean before it calls the EOImpl's doDML().
I'll show you the action method in bean which get's call on click of commit button in .jspx,
    public String commitAction() {
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding = bindings.getOperationBinding("Commit");
        Object result = operationBinding.execute();
        if (!operationBinding.getErrors().isEmpty()) {
            return null;
        return null;
    }In this method I put a break point at
Object result = operationBinding.execute();from here control doesn't go to EOImpl class.
Here is the .jspx code for commit button,
<af:commandButton   text="Commit"
                                disabled="#{!bindings.Commit.enabled}"
                                id="cb1"
                                action="#{CustomerProfileBean.commitAction}"/>Can I use both action and actionListener properties for same command button?
Is this technically correct?
Thanks,
Madhav.

JTree move operation

I have a piece of code which is doing a drag and drop on a JTRee.This code also needs to handle move and copy operations.THe move method does not work the way expected.When I do a drag operation the node gets dragged but is not removed from the parent although pls note that when all the node are removed under a parent and I click on the parent node the plus sign next to the parent disappears and also the nodes disappear. I am not sure what the problem is ..has anyone ever faced such a situation.
If anybody had any idea as to how to get a move operation on a JTree then your guidance for the same will be highly appreciated.
Thanks for your help

Thanks for the reply.I am removing the node from the model.
I am doing the drag and drop between 2 trees and that is when I have the above mentioned problem.
But when I drag within the same tree everything works fine.
Let me explain one thing here that I am using 2 different instance of the same class for the 2 trees is it something like only one of the tree is getting refrehsed and other one is not.If so then how do I ensure that both instance of the tree gets refreshed.Any clues ????

Hello Shah
You have to fill TABLES parameter <b>IT_METHODS</b>. Apparently you need to have at least one record there where BAPI_ALM_ORDER_METHOD-METHOD = 'SAVE' or 'DIALOG'.
I am not sure if the others fields need to be filled but this should be easily to find out.

Syntax error when creating Overwrite method - implicit enhancement

Hi,
I am working at a customer site, and need to implicitly enhance certain methods. I would like to create an Overwrite Method for the following class/method:
CL_CRM_MKTDEF_DEFAULTS_PERSIST -> HEADER_WITH_KEY_EXITS_IN_DBASE( )
I proceeded in the following way:
Open class CL_CRM_MKTDEF_DEFAULTS_PERSIST in class builder (SE24)
Select menu path Class -> Enhance
Create, or select, enhancement implementation ZCRM_MKTDEF_PRD
Select method HEADER_WITH_KEY_EXITS_IN_DBASE, select menu path Edit -> Enhancement Operation -> Add Overwrite Method
Click on u201CNavigation to Overwrite Exitu201D
After navigating to the Overwrite Exit, I click on "Check" to perform a syntax check (notice, I have not yet implemented any code. Everything so far has been done by the wizard).
Now, I get the following error:
Enhancement Implementation ZCRM_MKTDEF_PRD
Unable to interpret "IS_DEFAULTS_ATTR". Possible causes: Incorrect
spelling or grammar.
When I create Overwrite methods for any other method in the same class, the same error does NOT occur. As far as I can tell, there is nothing special about this method that should cause this error.
I would greately appreciate any help that any of you could give me on this one.
thank you and best regards,

Business operations in the studio

I have an existing web based application already running on weblogic that uses
ejbs. I want to make use of one ejb installed in this existing application in
weblogic studio to define a business operation. To do this, I guess I should also
deploy the same ejb onto "Weblogic Integration" application which is a separate
application ( or in other words add an ejbcomponent element to application element
of "Weblogic Integration" application and update application.xml in META-INF of
Weblogic/integration/lib). If I do this, this is essentially turning out to deploying
the same ejb into two applications. Is this correct. So deploying an ejb twice
in two different applications on a single weblogic server means giving them two
distinct jndi names. Is this procedure correct or is there a better alternative.

How to handle method based exceptions in webdynpro abap?

Hi ,
    I want to raise an exception from my method.....I am doing division operation inside my method...when I am entering a very large amount , that time I am getting run time error.....please someone help me to catch this exception and display on browser.
Thanks & Regards
Suman Kumar

Hi Suman,
You can catch the arithmetic exception by using exception class CX_SY_ARITHMETIC_ERROR as below
Sample code:
          data lv_ex_msg               type string.
          data lx_sy_error              type ref to CX_SY_ARITHMETIC_ERROR.
          try.
               "here goes your code
          catch CX_SY_ARITHMETIC_ERROR into lx_sy_error.
                           " you can get exception text as below
                         lv_ex_msg = lx_sy_error->get_text( ).
                         or
                     " lv_ex_msg = lx_sy_error->get_longtext( ).
          endry.
Hope this helps you.

Help in design methods

HI ,
i want to know if there is performance aspects and good design i do the operation in good way ,
this is regards insert , update , modify
I do read opration from the DB tables and i need to create or update the value
1. if sy-subrc = 0 i check if the data that i get form the
DB is equel to the data that i have, if yes dont do anything .
2. if sy-subrc = 0 and some records are different - > do update
3. if sy-subrc <> 0 - > insert the records to the DB via insert commend
i know that modify do both update and insert but my question if for my case
its good to separate the operation for two method despite i can do that in same method
1. methods handle insert
2. method Handle update
Regards
Joy

Hi Joy,
Basic rules about creating the methods would be:
- keep it smart
- keep it small
- let the method be responsible for certain task only
- minimize but don't atomize - which means do not create method just to execute one statement only. Class itself may then become very hard to maintain if too many methods are used.
Generally in your case it is really of no matter how you handle it, either in both or in one method. All in all they will be both responsible for doing very similar task. So you can use one method and pass parameter i.e. mode where I would be for insert, U for update, but it's always up to you which approach you take.

Marcin
