EJB3 - Architecture overview and encouraging re-use of business logic...

Hi all,
I am currently learning EJB 3 and have created a blog to share what I have discovered so far. My main interest is promoting re-use so that I can use Spring, EJB3 or another other communication framework.
I would value any thoughts on what I've written on my SpikyOrange blog.
Many thanks,
Rob.

your spring book seems to refer to EJB prior to the EJB 3.0 standard, when it was still incredibly clunky and hard to maintain. Seeing that you have the O'Reilly Enterprise Javabeans 3 book, I am convinced you will get on the right track now as I personally recommend that book everywhere I can (I get money from the author you know...)
Even if EJB 3.0 has improved vastly over its predecessors, there is nothing stopping you from combining parts of Spring with EJB technology, and/or even JSF (which in my opinion is one of the cleaner web frameworks around, especially with all the supporting libraries like richfaces and JBoss Seam).
One complaint about your blog: can you please consider using paragraphs? That large tree of text is hard to read this way!

Entity Beans and Session beans to represet Business lOgic

How cam we implement Entity Beans and Session beans to represent Business Logic.
Can anyone explain how can we do this.
Regards...

I have session beans calling method in entity beans and any client
doesn't have access to entity beans, only via session beans.
If i define security policy and method permissions for session beans
only, do entity beans use that permissions when calling their methods
from sessions beans OR should i define the security policy for entity
beans separately?If you want to set the permission on individual
methods of entity bean ( with different roles)
you have to do it separately.
If you want to delegate the Authenticated user along with
the method call to the Entity Bean you can use
run-as-identity-principal.
For more detail please check out the EJB2.0 Spec.

How can I get hardcopy Apple brochures and catalogs to teach and encourage people in my university community to use Apple products.

Apple has the best devices and software in today's ICT scape. Sadly, people in my University hardly use them. For some time now I have been teaching and sensitizing members of my university community, mostly professors and lecturers to use Apple devices to ease teaching, learning and personal activities. I have been able to get a good number people hereto buy and use Apple products, especially mobile devices. I'll need hardcopy catalogues, manuals and poster to enable get more effective as they is no Apple shop or dealer anywhere near.
How can I get these items?
Thanks.

Using a Single Library for Entire Site and When to Use Subsites

I'm hoping a discussion I am having with my coworkers can be solved. We are trying to decide two things:
Should the entire office be under a single site or should each division have their own site? Our Office has 5 divisions that contain 17 Branches, one site for business functions and one top-level site for the entire office.
Is it standard practice to create one huge library managed by metadata or should there be multiple libraries? I tend to think one library will be too hard to manage with regard to metadata and site columns and that libraries should be based on business
functions or subject domains (i.e., SOPs, Quality Documents, Business Documents, Technical Documents, etc).
Currently, several workflows, libraries and lists have already been created under our business functions site. In order to house everything under a single site, we would need to change the name of the site and move everything under it. I'm not
sure if changing the name of the existing site will cause problems.
I group these two items together because they really seem related. With everything under a single site, individual libraries, lists and workflows could get out of hand as everyone tries to manage their own division. But then so would a single
library for everyone. The problem with more than one site is that data cannot flow freely between sites (via workflows) and search would be less effective so some are against separate sites. So knowing one question may affect the answer for the
other.
Any thoughts on our library and site structure would be appreciated. Thanks.

As always the usual SharePoint consultant cop-out answer of 'it depends' is correct.
Having said that there are certain trends that are quite relevant:
It isn't common to use a single site collection for all sites. It can be done but it often leads to a state where you have a single monstrous site collection which is harder to backup, recover and maintain (see the boundaries and limits documents). The
default behaviour in most cases is to have a central 'shared' site collection then one per <group> where Group is a team that works on the same content, has broadly the same area of interest and access. That might be one for HR, one for the Support team,
one for the Sales team etc.
In terms of libraries there's a wide variation. If there' no difference in views, security and metadata then keeping the library count down is generally a good thing. However using multiple libraries can make life easier and better for users by allowing
more useful views, more secure by locking down libraries rather than using item level permissions (always a nightmare) and allowing more useful alerts and so on.
SharePoint architecture is a science but it's a really, really hard one to formulate into If/Then rules. So, broadly answering your questions I would lean towards multiple site collections and I generally agree with you on point 2, although if there's only
a small number of documents and simple structure then a single library might still make sense.

I downloaded Firefox 4 for my Mac running MacOS 10.4.11 and replaced my older version (because I didn't understand the meaning of the barred circle) and now cannot use Firefox at all. How do I get the older version back?

When I try to open FF4 I get the message it can't be opened because it is not supported on my architecture. I can't believe no-one else has had this problem. You must have a lot of internet duffers who don't really know what they're doing. I need to get my old version of FF back if I'm going to run it on my computer. I don't understand why an app as widely used as this doesn't have a pre-app that assesses whether one has the architecture to run a new version. You advertisement merely said OS 10, and "all systems". It did not specify a newer MacOS than my 10.4.11. Now I seem to be out of luck and will just use Safari.

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

What are the advanteges and disadvanteges of using pl/sql over hibernate

i knwo that pl/sql are well structure and provide a lot of functionalities with oracle databse , but my question is the hibernate might give some advnateges of scalability over pl/sql.
so what are the advanteges and disadvanteges of using pl/sql over hibernate?
and does oracle recommend using hibernate for connecting JSP with oracle 11i , or it is better to connect the JSP pages with oracle databse using pl/sql ?

812643 wrote:
but if i search for the diferencess then there are a lot of opinions about this ..., specially when they say that with hibernate you can integrate with any DB , and it provides object printed architecture, etc.All databases are not equal. This is a basic and fundamental fact. SQL-Server is not Oracle. Oracle is not SQL-Server. As it is the case with Sybase, Ingres, DB2 and other database products. They are all different. And there are some very core differences between them.
So how would a product like Hibernate treat these database products with their differences? By using the lowest common denominator. Which means your expensive database product is dumbed down - and even MS Access will likely have better and more features.
You also need to decide what is the "permanent" part in your architecture. What is going to the core? What is the expensive part? The app server (with Hibernate)? Or the database server?
What are you likely to change next year? The app server server? Or the database server?
In the vast majority of cases, the core is the database server. That is your biggest expense and investment. As it should be - as it holds that which is most precious to business, data. You want to ensure the integrity of that data. The accuracy of that data. Make sure that it can be easily backed up and recovered. Is flexible to use. Etc. Etc.
The database server is the core - and that is where you need to realise your return on investment. By using the database server to its full extent.
Hibernate does not do that. And in that respect, it is junk.
Why does it not do that? Because many Java developers are totally and fully clueless about what database servers are and how to use them. And want to use them as little plug-in black boxes - bit buckets that are only there to provide a data persistence layer. Instead of using the database server to its full extent, they instead use Hibernate, and try to do their own "+database thing+" in the app layer - and do it poorly and with utter lack of any scalability. (and no, only ignorant Java heads think that scalability means throwing more money and h/w at it)
My largest database processes billions of rows per day, every day, 356 days a year (between 350 to 450 million new inserts into a single table per day). And have been for several years now. It does so using PL/SQL. Using Oracle to its full extent. Then there are Java heads that cannot even design and code an app that effectively process 1% of this volume... and grasp at straws like Hibernate and other Java cr@p to "fix" this - when the actual problem is their total lack of ignorance in how to use and scale the database server.
Hibernate is trash - and a symptom of Java developers's ignorance of database technology.

0SD_C03 Sales Overview and Vendor Information

Hello,
I am using BI 2004s with Business Content 3.5. I would like to create a sales report such as sales by vendor. I am using the Sales Overview cube 0SD_C03 and tried to use the vendor information as an attribute from the material characteristic in this cube but the vendor information is empty. I am told by our consultant that this is because it is not part of standard business content.
My question is: Is there any other way to get Sales (billings) by vendor? What have other people used to get Sales by vendor. Have they just made a change to standard business content to include Vendor information?
Thanks.

Hi
The best option in this case in enhancing the business content by adding the required field Vendor and populating the related values
Before that you can check in R/3 whether any standard reports are there which lists of Sales by vendor. If such a report exists, you can just replicate the report to complete your task
One suggestion
Please check the following report in R/3 ..S_ALR_87014367. whether is fit for your requirement or search some other reports
Assign points if useful

When to use IN Queue and When to use OUT Queue

The architecture that we have is Client publishes the EDI 272 data to FTPS Server. We have ESB configured to pick the EDI data from FTP location, construct the B2B Header message and send to B2B. The B2B translates the EDI raw data to EDI XML. BPEL reads the EDI XML data from B2B. I have doubt here in using the IP_IN_QUEUE and IP_OUT_QUEUE. As per my understanding, IP_IN_QUEUE is used for messages inbound to B2B and IP_OUT_QUEUE is used for messages going out of B2B. If this is correct, ESB module would publish to IP_IN_QUEUE and BPEL would pick from IP_OUT_QUEUE.
I'm confused here because I read few examples in which the queues were used other way around.
Kindly clarify whether the usage of IN and OUT queus are correct.
Thanks,
Mani

HI Mani,
When B2B receives an inbound message from trading partner, it will send to IP_IN_QUEUE.
When Back application wants to send a message to B2B, Backend application has to send the message to IP_OUT_QUEUE. B2B picks up the message from IP_OUT_QUEUE and send it to trading partner.
The above mentioned queues are shipped with the product. However, users can can create there own queues.
Thanks and Reagrds,
Prasanna

Does Database initializer obsolete in EF 6.0 ? And we should use Migration instead of it.

In this tutorial
http://www.asp.net/mvc/overview/older-versions/getting-started-with-aspnet-mvc3/cs/adding-a-new-field
I see such code
public class MovieInitializer : DropCreateDatabaseIfModelChanges<MovieDBContext> {
protected override void Seed(MovieDBContext context) {
var movies = new List<Movie> {
new Movie { Title = "When Harry Met Sally",
ReleaseDate=DateTime.Parse("1989-1-11"),
Genre="Romantic Comedy",
Rating="R",
Price=7.99M},
new Movie { Title = "Ghostbusters ",
ReleaseDate=DateTime.Parse("1984-3-13"),
Genre="Comedy",
Rating="R",
Price=8.99M},
new Movie { Title = "Ghostbusters 2",
ReleaseDate=DateTime.Parse("1986-2-23"),
Genre="Comedy",
Rating="R",
Price=9.99M},
new Movie { Title = "Rio Bravo",
ReleaseDate=DateTime.Parse("1959-4-15"),
Genre="Western",
Rating="R",
Price=3.99M},
movies.ForEach(d => context.Movies.Add(d));
But when I went to https://msdn.microsoft.com/en-us/data/ee712907 I see only migration database
I am newbie at EF. I am focusing on Code First. I have an idea that
DropCreateDatabaseIfModelChanges
and another DataBase initializer is not acutal for EF 6 but it was used in previous version.
On the other hand from names of this
Database initializer is for database initization
Migration for database structure changing
Before learning I decided ask this question
Does Database initializer obsolete in EF 6.0 ? And I should use Database Migration instead of it ?
My .NET Blog with projects and feedback.
Since May 30, 2014 I am waiting for Microsoft fix
these 2 bug. If you know how to speed them up, please help

Hello,
>>Does Database initializer obsolete in EF 6.0?
I do not know why you think so, if the team decides to make the database initializer obsolete, I think they would make a markup as Deprecated, however, there is not such a markup on that method on MSDN document. And the Database initializer method is useful
when we play with automatic migration. In your case, the DropCreateDatabaseIfModelChanges database initialization strategy, would delete the original database and create new one according your new model. Of course, data would be missing. If you are under a
scenario need to make a test to recreate the database frequently, this one should be ok.
Currently, there are four database initialization strategies could be used:
CreateDatabaseIfNotExists<TContext> Class
DropCreateDatabaseAlways<TContext>
DropCreateDatabaseIfModelChanges<TContext>
MigrateDatabaseToLatestVersion<TContext, TMigrationsConfiguration>
You could use one of them for a proper scenario.

With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
I am going to have over 50 buttons in a page, Why? This would be a most unusual UI paradigm. I've never seen such a page, which suggests that whatever you want to do is normally done another way. Please explain the requirement in more detail.
just wanted to know if its possible to do something like this in java.
Java is not used in programming APEX UI behaviour. Java and JavaScript may share initial syllables, but they are not closely related.
It's possible to achieve a great deal in JavaScript, but a clear definition of the requirements is necessary. Do you mean the buttons should be dynamically generated? If so, yes, this is possible in JavaScript. What would drive the process?
Also, i would like to have dynamic action on it, for example, when the button is pressed, fill a string of text into other items(text field) within the page. Without more detail its not possible to make any specific suggestions. For example, I certainly would not want to create 50+ individual dynamic actions relating to different buttons.

MM02 - Enable options change number, change overview and change documents

I am with the following problem: I enter the transaction MM02, I enter the material 1000765, I select the view "Classification". Later I access the environment option from the menu bar and options for change number, change overwiew and change documents are disabled.
How do I enable these options change number, change overview and change documents?
Regards,
Sérgio Salomã

Hi Sergio,
If we activate the change documents for classification data, then we will be able to see the CHANGE DOCUMENTS for characteristic values through CL20N transaction (CL20N via menu ENVIRONMENT --> Change Documents) or MM02.
For reference please check SAP Note 65124.
For enabling change documents for classification data in SPRO --> Cross-Application Components --> Classification System --> Classes --> Maintain Object Types and Class Types.
In this enter into MARA table entry. Inside that corresponding to the respective CLASS TYPE (say 001) enable the CHANGE DOCS check box in Classifications part (For enabling this please check SAP Note 65124). Then for this CLASS TYPE (say 001) inside the OBJECTS folder, enable the CHANGE DOCS CLASS checkbox also.
Now in MM02 and in CL20N under menu Environment --> Change Documents you can view all the changes done to that characteristic values.
Once the change documents is activated, then we can get the change documents details in CDHDR and CDPOS tables. The OBJECTCLAS may be "CLASSIFY". We can also use the "CLLA_CHANGE_DOC_CLASSIFICATION" function module to fetch the data from these tables.
Hope this helps in solving your issue.
Thanks and Regards,
Harish kumar.

Connectivity between SQL Serevr 2008 and SAP BW using Microsoft Connector 1.0

Hi ALL
         I am trying to connect to SSIS 2008 to SAP BW using Microsoft Connector 1.0.
Following are stepes I performed.
1. Created RFC on SAP BW Server.
2. Created Prcess Chain in SAP BW.
3. Created SSIS Package using SAP BI Source. Here I set Execution Mode : P Trigger   Process Chain.
The process chain is executing fine on SAP BW Server, But it is unable to send back a
notification to SSIS package. And here my SSIS package failed.
I am getting following error message :
[SAP BI Source] Information: Process Start Process, variant Start Variant for MSBI has status Completed (instance D8Z84GJ2RLV7WCI2IYK5CZ1R3)
[SAP BI Source] Error: An internal exception occurred.
Microsoft.SqlServer.Dts.SapBw.Connectivity.ERPException:
An error occurred during the dispatch of the incoming function. The last return code was "RFC_FAILURE".
Before this error I am getting following messages are :
[SAP BI Source] Information: Process Data Transfer Process, variant Z09_O101 -> Z09_H101 has status Active (instance DTPR_D8Z84GJ2RLVZKYTTUHZRFEG0V)
[SAP BI Source] Information: The component is waiting for a notification.
Is there any way to test the both the way connections? I mean SAP BW -- SSIS &                SSIS --- SAPBW.
Can any one please explain me entire connectivity architecture between SSIS and SAP BW using Microsoft Connector 1.0. (I mean how these RFC are working and how SSIS is pulling the data from SAP BW)

I am having the same problem. We actually loaded data a few times but now it does not work. It is amazing that we cannot find help for this problem. Has anyone been successful using the BI connector 1.1 to load data to a BI system using SSIS. I think
this had to do with either a DLL problem on the machine running SSIS or the Service Pack level of the BI system. I cannot find any documentation showing versions. I have looked through the documentation that was written back in 2008 but can't seem to
get it to work.
Sorry we are trying to push data (BW Destination) to BI it looks like you are trying to get data from BI.
