Advantage Of Databrowser Object Over The RecordSet in Navigation

Is there any advantage in using databrowser object for user defined screen navigations, instead of recordset

When you have an UI item settled as browse by, for user tables on a user defined Form
it is very useful because it activates the browse by icons on the toolbar, it seem like magic when you navigate trough your data, all the items that are assigned to a DBDataSource change accurately.
But, when you have data from different datasources, you need to update them changing your code,
I think, this solution is not complete but helps saving time of programming.
hope it helps

Sending Connection Object over the Network using RMI

Hi,
How can a Connection object be sent over the network and run on another JVM. I need to hold connection object to execute processes one after other, that require Oracle connection without ever connecting again. I do not have J2EE container or webserver setup to hold connection/connectionpool,but need to run the process on command line. I am using RMI infrastructure to pass parameters/return values but connection object is not serializable and connot be marshalled and failing. Please explain, if there is another way using JDK 1.4
Sudheer

I think that what you want to do is connect to the database on the RMI server object, then use the server object from your remote clients to execute the processes you require to rrun.

I don't believe this is possible. A connection object has a number of associated structures on the operating system, which generally makes it impossible to move. From a fundamental networking level, you also cannot, in general, cause a connection to machine1 to start communicating with machine2-- that would introduce all manner of security problems.
Why don't you want to just create another connection on the other machine?

Distributed Objects over the internet

I'm hoping that someone can help me out here. I'm trying to get distributed objects to work on a game I'm developing. I can make it work if I run both the 'server' and the 'client' on the same machine, but when I try to set it up for use over a network, it crashes when trying to get the rootProxy.
Here's the code for vending the object:
id theServer;
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
MYMessageServer * server = [[MYMessageServer alloc] init];
NSSocketPort * receivePort;
NSConnection * theConnection;
receivePort = nil;
theConnection = nil;
receivePort = [[NSSocketPort alloc] initWithTCPPort:1234];
theConnection = [NSConnection connectionWithReceivePort:receivePort sendPort:nil];
[theConnection setRootObject:server];
[theConnection registerName:@"server"];
theServer = [[theConnection rootProxy] retain];
[[NSRunLoop currentRunLoop] configureAsServer];
[[NSRunLoop currentRunLoop] run];
[server release];
[pool release];
return 0;
This runs fine and seems to vend the object without a problem.
Here's the code for trying to access the vended object:
NSSocketPort * sendPort;
NSConnection * theConnection;
sendPort = nil;
theConnection = nil;
sendPort = [[NSSocketPort alloc] initRemoteWithTCPPort:8081 host:@"192.168.0.5"];
theConnection = [NSConnection connectionWithReceivePort:sendPort sendPort:nil];
server = [[theConnection rootProxy] retain];
if (nil == server) {
NSLog(@"Error: Failed to connect to server.");
} else {
[server setProtocolForProxy:@protocol(MYMessageServerProtocol)];
[server addMessageClient:self];
[server broadcastMessageString:[NSString stringWithFormat:@"Connected: %@ %d\n", [[NSProcessInfo processInfo] processName], [[NSProcessInfo processInfo] processIdentifier]]];
When I use the defaultConnection for the vending of the object and localhost for accessing it on the same machine, everything runs just fine. However, when i try to use the TCP and setup the connection through the network, it crashes on server = [[theConnection rootProxy] retain];
If anyone can make suggestions or offer examples of how to set up this, I would be extremely grateful.
Thanks.

Objects over the network

is it possible to read in an object from a reader.println(Object x); type method?

For your networking questions, first read:
http://java.sun.com/docs/books/tutorial/networking/index.html
(read "Overview of Networking" and "All About Sockets")
That will get you started with a simple client/server package. Then go to the API (http://java.sun.com/j2se/1.4/docs/api/index.html) and look at the java.io.* package. You'll probably want to peek at the various Input/Output stream classes for using Objects (i.e. ObjectInputStream/ObjectOutputStream). It shouldn't be too difficult to figure out all you need from the above tutorial and the javadoc API. Once you get going, if you have problems, post specific code and/or exceptions here and it'll be easier for people to help.
Good luck

Yes. By sending its values by any other means, like as XML.

Advantages of using BO over tools provided in BEx

Hi,
I am wanting to know if there is any documentation enlisting the advantages of using BO over the tools provided in BEx.
Also, what is the advantage of using BO analysing data from cubes in BI 7.0 than accessing data from SAP R/3 directly.
Thank you.

Hi
Advantages of BO (as well as other Query/Reporting) are that they provide robust end users interfaces
in terms of designing queries, reports and also run on a standalone desktop client. Their user interface is
easy to use and much easier environment to design manus, drop-down boxes/lists and buttons and also provide wizards to help users guide. These tools can also work against several heterogenous data sources.
There are several factors one needs to keep in mind when selecting 3rd Party tools for SAP BW. A few are listed below:
BO uses OLEDB for OLAP API via BEX query. This causes extra overhead because here you have BEX resources and then you add up BO resources to manage infrmation to/from BEX query over the OLEDB interface. Some vendors, like arcplan, use OLAP BAPI to access BW data. This API has somewhat lower overhead because it bypasses the OLEDB for OLAP layer.
As you know that BEX is MSExcel based. It is not easy to build sophisticatecd user interfaces without doing extensive VBA or Macro programming.

Is it possible to create a 'layer' over the top of a PDF in Captivate?

I am trying to integrate a 3dpdf within captivate 8 for a software training program, for this it is important to retain functionality to the pdf menu, Captivate handles this well : ) HOWEVER on importing the pdf it becomes clear that the pdf 'trumps' other objects such as clickable areas or text, which therefore don't seem to appear when published. I also wish to provide 'blocked' areas by putting transparent objects over the top of the pdf so as to control the learning process, which also doesn't seem possible on initial inspection.
Does the PDF exist outside the timeline?
Does anyone know how to layer objects over a pdf object that will remain there when published?
Many thanks!

How/where do you want to accomplish it?
Within the document? Using Acrobat? Using another application?
Using Acrobat within the document would be possible using Acrobat JavaScript. You can access the annotation objects of your document, and you then can evaluate the properties of each of these objects. Have a closer look at the Annotation Object section in the Acrobat JavaScript documentation.
You will look for the contents property, and evaluate its content. When you have found something looking like a URL, you can create a link (using the rect property of the annotation), and you have what you want; you might then think to destroy the annotation, as it may overlay the link.
Hope this can help.

What is the advantage of using IB to create XIBs/Class Objects over coding?

Hi all,
I hoping someone can provide me some pros and cons as to when I should use IB to create XIBs and/or class objects as opposed to directly coding them.
For example, if I choose Apple's Template for creating a Navigation Based Application (cocoa touch), the project creates two NIB files - MainMenu and RootViewController.
However looking at one of demo apps SimpleDrillDown, it does not have a RootViewController XIB and instead creates it via code.
Another example from the same two apps is that the template generates a "Navigation Controller" class object in the Mainmenu.xib. SimpleDrillDown does not bother with this in the XIB, but uses code to generate the controller:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Create the navigation and view controllers
RootViewController *rootViewController = [[RootViewController alloc] init];
UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
self.navigationController = aNavigationController;
[aNavigationController release];
[rootViewController release];
// Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
as opposed to the template which only needs this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Configure and show the window
// Navigation Controller is defined in MainWindow.xib
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
So what are the advantages of each approach. Why does apple suggest one approach and yet all its demos use another.
Any thoughts, answers gratefully received.
TIA, Michael.

You can do whatever you're comfortable with, but most of the best Cocoa programmers--the ones on the Mac, I mean--recommend putting everything you can into Interface Builder.
It's a little like the difference between writing a program to do a bunch of financial calculations and using a spreadsheet. Yeah, the program can do everything the spreadsheet can--and more besides--but you'll find it far easier to create, use and modify the spreadsheet.
Interface Builder takes away a lot of completely meaningless choices ("What order should I create the objects in? How should I name the variables? How should I create their frames? What order should I set the attributes in?"), leaving you with an interface optimized for creating and arranging objects, and allowing your code to focus on what you really do need to think about--your application's logic.
(By the way--part of the reason Apple's demos don't all use Interface Builder is that the very first SDK releases didn't have it. Back then, you had to create all your views programatically. Believe me, I have no wish to go back to setting autoresize masks manually. Now get off my lawn, whippersnapper.)

Advantages of BW SD reports over the SIS

Hello BI experts,
Would like to present the advantages of BW SD reports over the SD SIS reports.
1) Please provide me three main advantages and benefits to clients implementing BW SD reports over the SIS reports.
2) Are there any reports in the SIS system which are limited and BW has an advantage over them ?
3) What are the general information for hte SIS reports.
4) Any idea where I can find the SIS reports.
Your feedback appreciated.
Regards,
BWer

Hi.......
SIS is a part of Logistics information system (LIS). SIS reports use the following characteristics:
Customer
Material
Sales org.
Shipping point
Sales Employee
Sales office
There are number of SIS std reports. But as you can see they concerned mainly sales and distribution area. They are build on LIS structures. However, you can create custom structures and build non-std reports.
BW SD reports may be build on data provided by these old LIS structures (practically the same reports as in SIS). But LO cockpit provide new data sources with more information. So, std BW SD-related reports give more information and more flexible.
Additionally, to this SD reports we can add CRM reports.
And finally, BW flexibility allows us not only to get data from sales info, but also to join it with data from the other application areas, for example with materials management or controlling.
Hope this helps........

Need to send object instances over the network

I found no other way to implement a switch case to cast objects on both sides to solve my problem.
Basically I need to send objects over a network protocol based on XML, the object is sent inside XML
converted in base64, overall encoding of XML is utf-8.
Let's suppose in my network there are 2 peers connected via socket.
I have multiple instances of different types on both peers but I want to keep these instances
synchronized. If something changes on side A, side B must receive that instance and replace
it in the correct place (just one way, from A to B).
When I receive such instance on B I want to cast it to it's proper instance
of it's proper type and I am scratching my head on how could I implement this without some
sort of unique ID table and switch case.
If I had 1 instance per type could it be done easily?
But I need to keep in synch many instances per type.
Is there any dynamic casting that I can trigger based on some type/instanceID information
I could send along the object?

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

A business object is a master record within the Measurement System, and is defined as part of the measurement class within Customizing.
Examples of business objects are wells, well completions, and measurement points.
Once the measurement object is maintained, it is saved with the business object so that when viewed, the measurement object is part of the business object.
regards,
Siddharth.
