Business Delegate - best way to do it?

First of all I have to say that I'm using local interfaces so client and SLSB EJB are in the same JVM.
I would like to implement business delegate to make abstraction in case something changes later.
1. Does BD contains local interface to EJB as instance variable or something else?
2. My client is web based so should I keep BD in HttpSession to prevent creating BD for each method call or implement some other pattern? If so, which one do you recommend?
I would just like to hear from you guys how to implement so I wouldn't speend to much time on creating BD or EJB.

This is the normal procedure:
When you use the LiveUpdate DOS option a Windows Format Disk dialog pops up. Don't check any options (especially the system disk one). When the format is complete exit the dialog. LiveUpdate will copy files to the floppy.
To flash, put the floppy in the drive and reboot the computer. A freeware version of DOS will boot, create a ram drive, copy the flash file and bios image to the ram drive, and then execute the flash file.
You will be prompted to OK proceeding. If you do, the bios is erased, the new image is copied and then checked. A message will then be displayed that you can reboot the computer. Pop the disk out and press Ctrl Alt Delete.
When the computer reboots, press the Delete key, go into the bios and check/reset all settings.

Icloud for small business..best way ?

Dear people,
I am looking for a good "working in the cloud" solution for a small company.
The company consists of 6 people, each one having a mac which runs Yosemite, Adobe CC apps and Iwork apps.
Now my wish is that these people can work with all stated applications fully in the cloud.
So they all have to have acces to the documents made with Adobe CC apps, Iwork apps and the ability to open these documents locally.
without the need to first download these docs to their local mac.
Also, these people should also have the ability to work in the cloud when they are at home with a mac.
Now i am wondering what is the best working, stable, fast and good working solution to establish this ?
Preferably with the most cloud storage space for little money
I assume the new Icloud from Apple is not an option, cause it is tied to only one person (one Apple ID), while not one but 6 people
need to work with it.
Do i need to look for some external solution, such like box.com ?
I am a total noob in this area, hope to see some good advice.
Many thx in advance !

What is the best way to create business documents in CRM

Hi All,
What is the best way to create business documents like contract, sales order, debit memo etc in CRM ? Unlike R3 we can't use our good old BDC with recording. Moreover for most of them although there are Business Object but no BAPI to creation so what is the way ? I found in SDN there are two MAGIC Function module CRMXIF_ORDER_SAVE. Do I need to that alawys ?
Is it nees to via IDoc and cannot be done just by calling from ABAP program ? The input parameter of the FM is a complex deep structure.
Please help.

Ashim,
Try looking at the program:
CRM_TEST_ORDER_MAINTAIN
I think that should help you figure out the parameters.
Good luck,
Stephen

Business rules to implement - BEST way - triggers and mutating table

I have the following table where it has Foreign Key defined on itself(self reference for parent_id column which can be null or valid site_id)
create table test_virtual_site
site_id number CONSTRAINT site_id_pk primary key,
parent_id number CONSTRAINT parent_site_id_unq UNIQUE ,
closed_date date default NULL ,
CONSTRAINT check_self_ref CHECK(parent_site_id <> site_id), --avoid self refernce
CONSTRAINT check_valid_site foreign key(parent_site_id) references test_virtual_site(site_id)
I have the following business rules to implement and my problem is related to their implementation
1)     A check should be made that Site_id specified as parent_id should not be a child of any other store (parent should have its parent_id column as NULL)
Site_id Parent_id
1
2 1
3 2 =>NOT VALID 2 is a child of another store
2)     Parent is not closed
Site_id Parent_id Closed_date
1 10-May-2005
3     1 =>NOT VALID 1 is a closed
3)
when parent store is closed - updated so at closed_date is not null
Want to set the parent_id as NULL for the child store.
OR
SET the closed_date for child store too same as the parent_store.
Example
Site_id Parent_id Closed_date
1
1 2
Update test_virtual_site
SET closed_date = sysdate
Where site_id = 1 ;
Through Trigger
Site_id Parent_id Closed_date
1     22-Mar-06
1 2 22-Mar-06
OR
Site_id Parent_id Closed_date

When I am trying to do the above mentioned through constraints I am running into mutating trigger problem. Can you please guide me what is the best way to handle the above-mentioned scenarios.
I am aware that I can avoid the 3rd problem using the following
-- - Initialize an array in the before statement trigger.
-- - Add the processed rowid to the array in the after row
-- trigger.
-- - In the after statement trigger: get each rowid from the
-- array and process it. When all rowids are processed, clear
-- the array.
BUT for 1 and 2 I need to look at the parent specified , the parent exists in the same table BUT I can not perform the lookup from the BEFORE INSERT ROW LEVEL trigger but I want to ensure at the row level , so if the parent store is closed or parent specifed itself is a child(not permissible) I want to rollback the insert RAISE_APPLICATION_ERROR.

The best way to implement business logic to a .JSP ?

Hi experts,
I want to implement some business logic to a .JSP file wich is in my modified
<b>com.xxxNew.portal.usermanagement.admin.pa</b>r file!
For examle creating different roles for useres by registration dependently what they inseret in the registration.jsp!
What is the best way to do this? I have tried out to create a stateless session bean for this. Is this the right way?
Can someone give me information how can I access this bean from my JSP (.par file) and how can I upload it to the portal?

Hi,
Here is the document about Calling J2EE Applications from Portal Applications:
http://help.sap.com/saphelp_nw70/helpdata/en/42/9ddf20bb211d72e10000000a1553f6/frameset.htm
So in your JSP do the lookup of your EJB.
I do not think using EJB at this level is really good, as you do not deal with DB, security and transactions in your code.
http://www.jguru.com/faq/view.jsp?EID=126400
Why not just use a portal component like JSPDynpage for this purpose?

Best way to structure Business Logic

Hi Experts,
I am using Web Dynpro for my front-end and application services for the back-end. Which of these is the recommended way to structure the layout of my business logic:
1) Keep everything in the 'src' folder of the CAF ejbmodule. Structure through the use of packages.
2) Create an external Java DC, keep all code in there and call the code from the application services. Structure code through both packages and the use of multiple DCs.
3) Create a child Java DC in the CAF ejbmodule project, keep the code there. Structure code through both packages and the use of multiple DCs.
4) Some other way which I do not know of???
I think that (2) is the best way to to this, but I'm not sure and I also don't know how to make the code in the Java DC accessible from the CAF in 7.1. In 7.0 one was required to assemble the Java DC into a J2EE Server Library project and then create the required dependencies. How does this work in 7.1?
Thanks,
JP

Hmm, I guess it would be a rather tough task to have a mapping between all classes (or even packages) and DCs. However it should be fairly intuitive to infer the DC from the class / package name. If still in doubt, you can search for its usage on help.sap.com - most probably you'll find the DC name as well therein.

According to the <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/javadocs">NW public javadocs</a>, the classes in the com.sap.tc.webdynpro.* packages are "Services in the Web Dynpro runtime environment that can be called by custom coding in Web Dynpro applications", so they're not intended for general use in any type of app.

Using Microsoft Exchange to access Gmail (Google Apps for Business) contacts, what is the best way to sync the Corporate Directory?

Using Microsoft Exchange to access Gmail (Google Apps for Business) contacts, what is the best way to sync the Corporate Directory? For instance, we have 40 staff members and wish to populate each phone with the Gmail profile. Right now we have a third party Android app that does this and copies my contacts to each phone. This is problematic. Any solutions to populate a phone with email and phone contacts? Even it it requires double entry for me...thats ok.

Oh, I meant Leopard does do more than Tiger Server.
I don't know enough about Server, even less abut Syncing.
SL is to new, not enough time to iron out the kinks yet imho.
One day SL will be better than Leo, but...

What is the best way to set up business accounts with multiple ipads?

Here are three different methods >
How to use multiple iPods, iPads, or iPhones with one computer, http://support.apple.com/kb/HT1495
This article > iOS: How to transfer or sync content to your computer, http://support.apple.com/kb/HT1296
suggests using contacts groups.
When syncing contacts, you can choose to sync all of your contacts or only selected groups.
You can select a group of contacts to which all new contacts created on your iOS device will be added.
You can set up groups in the Address Book application.
If you are all going to use the same iTunes apps library, turn off "Automatically sync new apps" in the apps tab just below the list of apps. Then you won't get new apps on your device unless you select them.

Best way to delegate events to parent

Hi to all.
I have a problem with a GUI i'm programming. I have the Shop class that extends a JFrame and have several JPanel and other components. Inside one of this JPanel i have an InventoryPanel that extends JPanel and contains JTextfields and a JList.
I've no problems to handle events inside InventoryPanel, but depending on some factors (i.e. the property of objects selected in the JList) sometimes the event must be delegate to the Shop class (so i can disable/enable buttons or set text). Which is the best way to do such a thing?
I thought i could call a method of Shop, but InventoryPanel "doesn't know" how to reference it... should i pass the reference in some way (constructor)?
Or should I conditionally delegate in some way the event to a Shop EventListener? and in this case, how can i do this? I searched through the tutorials and the forum, but it's not too clear to me
Thanks for any help

The simplest way to implement addListener and removeListener is something like:
public class Foo
private Vector mFooListeners = new Vector();
public void addFooListener(IShiftListener listener) {
    mFooListeners.addElement(listener);
public void removeFooListener(IShiftListener listener) {
    mFooListeners.removeElement(listener);
protected void fireFooEvent(FooEvent event) {
     for (Enumeration enum = mFooListeners.elements(); enum.hasMoreElements(); ) {
      IFooListener listener = (IFooListener)enum.nextElement();
      listener.fooHappened(event);
// and somewhere in here you do something that requires a call to fireFooEvent()...
}Note that this code was developed under JDK 1.1.4 so I used Enumeration instead of Iterator. Other than that this is a respectable way to handle listeners.

Best way for a thread to wait without busy-waiting

Hi!
I have a thread that has nothing to do but to monitor the status of a variable
public static boolean askToClose. This variable is set by other
threads to indicate that this thread should stop now. But I don't want the thread
to busy-wait like in this piece of code :
public void run() {
     while (!askToClose) {
          Thread.sleep(1000);
     cleanAndStop();
}I'm new to Thread programming in Java so I'm not sure what's the best way to wait
for an event without busy-waiting. I've tried using interruption instead of
monitoring for the boolean variable :
public void run() {
     try {
          synchronized (this) {
               System.out.println("WAITING");
               wait(0);
     catch (InterruptedException e) {
          System.out.println("INTERRUPTED !");
     cleanAndStop();
}and the other threads would simply call myThread.interrupt() instead of setting
askToClose = true;And I've also used a LinkedBlockingQueue :
public static LinkedBlockingQueue q = new LinkedBlockingQueue();
public void run() {
     try {
          q.take();//Waiting
     catch (InterruptedException e) {}
     cleanAndStop();
}and on the other threads :
MyThread.q.add(new Object());Which one is the best solution ? Do I really avoid busy waiting with this code? Is
there a better way of doing this?
Thx for your help !

Your wait() based solution is OK, except that the other thread should
use
synchronized()
notify();
}

Business Delegate and Session Facade Pattern

Hi!
The only way to use the Session Facade Pattern, is if I use EJB for Persistence.
Is valid to do this?:
I use Ejb for simple update, insert querys. From my business delegate I call the Session Facade Layer, and from this I invoque Entyties for persistence.
But if I have complex querys, is correct to make PL SQL Procedures and do the following:
From my business delegate I call to the Dao layer, and from this via JDBC I call the Procedure.
Please explain me the best form to do this, having complex querys for reporting and simple querys for inserts/update.
Is valid to combine the use of CMP (for simple persistence cases), BMP (for complex persistence cases), and JDBC for complex select querys with multiple result rows.
Thanks!!

It depends on your design goals. One of the forces driving the use of patterns is the desire to tier an application and abstract the internals of each tier away from the other tiers. One (normal) benefit of this methodology is that the application should become more portable. Now, if you are using PL/SQL, BMP and CMP, you are mixing and matching portable versus proprietary. This is okay. But you should abstract away whether you are using PL/SQL, BMP or CMP from the business layer (or domain model). Ideally, you could completely swap database technologies (say from relational to object) and only have to re-write your integration tier (your DAO's).
Session facade is simply a glorified Facade pattern. It abstracts the lower-level details of what you are persisting and instead forces you to think in terms of objects. You can use a facade without even remotely touching EJB's. It just so happens that, historically, EJB containers made a mess out of scalability when it came to entity beans. The "session" facade refers to a facade pattern implemented in session beans (that have fewer scalability problems) communicating with the entity beans which do have scalability problems.
So... to make a long story short, use whatever persistence mechanism you desire. Remember that you should be able to completely switch your persistent store from one type or another and simply re-write your DAO's (or CMP deployment descriptors). Using a facade pattern can help towards this end, but don't make it a straightjacket.

The session facade is borrowed from the facade pattern, so you could have a facade to almost anything.
A session facade is usually against other beans...for example if you
(Not deployed as CMR)
1. Address bean
2. Phone Bean
3. Customer bean
as entity beans then you can build a session facade such as
CustomerFacadeBean which will CreateReadUpdateDelete(CRUD) address and phone as well when a customer is CRUD ed.
In your case you said you have very complex sql's so one way would be
Business Delegate -> Session Facade -> (Bean Managed) Entity Bean -> DataAccessObject.
If you think this is a overkill then, write a custom pattern such as DataDelegate
DataDelegate -> (Bean Managed) Entity Bean -> DataAccessObject.
In the above scenario you should be quite sure that the system will not evolve into a case mentioned above such as when customer is deleted a phone and address object are also thrown away.
You said this scenario
Business Delegate -> DAO..
I don't think this is a good idea because, a business delegate is a proxy against business objects....and usualy in J2EE business objects are session beans. Entity and DAO objects are data objects not business ones.
Besides if you do the above scenario you will end up wiring all the transactions, etc etc in your DAO which is not a good idea.
Although you could use BusinesDelegates against entity beans it will lead to a misnomer.

When I send a webpage via email, some of my recipients are unable to see it properly. The website was made with iWeb, and a Mac person advised me this was the best way to do an email campaign with iWeb, but it's not working for a lot of my customers - why

I have recently created a website for my family's business. When we bought the Macbook the guy in Apple said the best way to send an email campaign to our mailing list was to publish a hidden page, find it in the browser on Safari, then share it via email, so that is what I do. For most of my customers this works fine, however I have a number of people each month who cannot see any of the content of the email. I have added an 'If you can't see this email properly...' link at the top of the page, with no shapes or images etc near it, but even that does not appear for them.
I am a self-taught novice unfortunately, so haven't a clue what the problem is. I'm not sure of the operating system, but we bought the Macbook in May and it has all the recent updates installed. I have just had a new baby so can't get into the store fdor a one-to-one, so if anyone could explain why this happens / what I can do about it, I would be very grateful! Thanks!

If you think getting your web pages to appear OK in all the major browsers is tricky then dealing with email clients is way worse. There are so many of them.
If you want to bulk email yourself, there are apps for it and their templates will work in most cases...
http://www.iwebformusicians.com/Website-Email-Marketing/EBlast.html
This one will create the form, database and send out the emails...

The alternative is to use a marketing service if your business can justify the cost. Their templates are tested in all the common email clients...
