EJB related question

Generally speaking, for implementing the business logic we need to develop the EJB.
I know if one uses the JDeveloper as the web developing tool, he/she does not bother to implement EJB because there is the BC4J.
But if a developer uses other tools such as Websphere studio, does he/she need to develop the EJB from scatch?
Or if somebody used Websphere before, is there some better way to implement the business logic if the EJB is not employed?
Thanks.

Business Logic doesn't have to be in EJB when you develop in Java (doesn't matter which tool you use). In many cases using simple servlets and classes to implement your business logic is good enough and EJB can be an overkill for many tasks.
For example check out this book:
http://www.amazon.com/exec/obidos/tg/detail/-/0764558315/002-2811268-1673630?v=glance
BC4J is a Java framework that among other things simplify writing your business logic for applications that are database driven. It can be deployed as simple classes or as an EJB.
As far as I know websphere doesn't offer a framework like BC4J and you end up writing a lot more coding manually.

Missing ejb relation description file after deploying ejb module

when i deploye a ejb module to oc4j_extended_1013_dp4 successfully, it's can't find the file ejb-jar.xml that descript ejb relations and navigators.
why?
how can i defense it ?

however, i repeat my question
i use two file descript ejb module in MEAT-INF directory, one name ejb-jar.xml , another name orion-ejb-jar.xml
my ejb jar-package contrained them.
after deploying , i only find orion-ejb-jar.xml in application-deployments/myapp/myejb

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.
1.)If i am using the continuous output mode.and the size of generated data is less than 32 MB.If i want to preload the memory,what should i do?I want that first of all i load all my data to onboard memory & then i want to make start the transfer between 6534 & peripheral.Is it possible?As per me it should be.Plz tell me how should i do this?I think that in normal procedure the transfer between 6534-peripheral & outputting data from pc buffer to onboard memory works parallely.But i don't want this.Is it poss
ible?
(2).Similarly in finite input operation(pattern I/O) is it possible to preload the memory and then i read it?Because i think that the PC memory will be loaded automatically when 6534 acquires the data and then when we use DIO read vi the pc buffer data will be transferred to application buffer.If this is true,i do not want this.Is it possible?
(3) One more question is there if i am using normal operation onboard memory will be used bydefault right?Now if i want to use DMA and if i have data of 512 bytes to acquire.How will it work and how should i do it?Please tell me the sequence of operations.As per my knowledge in normal DMA operation we have 32 Bytes FIFO is there so after acquisition of 32 bytes only i can read it.How it will known to me that 32 bytes acquisition is complete?Next,If i want to acquire each byte separately using DMA interrupts what should i do?Provide me the name of sourse from which i can get details about onboard memory & DMA process of 6534 specifically
(4).In 6534 pattern Input mode,if i want to but only 10 bits of data.and i don't want to waste any data line what should i do?

Hi Vishal,
I'll try to answer your questions as best I can.
1) It is definitely possible to preload data to the 32MB memory (per group) and start the acquisition after you have preloaded the memory. There are example programs on ni.com/support under Example Code for pattern generation and the 6534 that demonstrate which functions to use for this. Also, if your PC memory buffer is less than 32MB, it will automatically be loaded to the card. If you are in continuous mode however, you can choose to loop using the on-board memory or you can constantly be reading the PC memory buffer as you update it with your application environment.
2) Yes, your data will automatically be loaded into the card's onboard memory. It will however be transferred as quickly as possible to the DMA FIFO on the card and then transferred to the PC memory buffer through DMA. It is not going to wait until the whole onboard memory is filled before it transfers. It will transfer throughout the acquisition process.
3) Vishal, searching the example programs will give you many of the details of programming this type of application. I don't know you application software so I can't give you the exact functions but it is easiest to look at the examples on the net (or the shipping examples with your software). Now if you are acquiring 512 bytes of data, you will start to fill your onboard memory and at the same time, data will be sent to the DMA FIFO. When the FIFO is ready to send data to the PC memory buffer, it will (the exact algorithm is dependent on many things regarding how large the DMA packet is etc.).
4) If I understand you correctly, you want to know if you waste the other 6 bits if you only need to acquire on 10 lines. The answer to this is Yes. Although you are only acquiring 10 bits, it is acquired as a complete word (16bits) and packed and sent using DMA. You application software (NI-DAQ driver) will filter out the last 6 bits of non-data.
Hope that answers your questions. Once again, the example code on the NI site is a great place to start this type of project. Have a good day.

Two related questions: ColdFusion 10/Java applications and J2EE supported servers

I have two related questions:
1. CF10 and integration with Java Web applications
We have a couple of Java applications running on JRun and interfacing with CF9 applications. The JRun clusters were created through the JRun Admin and, apart from lack of Axis 2.0 support, have served us well for years now. And, as would be the case, the ColdFusion9/Java/Flash application is a critical public-facing application that the business uses for bidding on projects.
It appears that with ColdFusion 10 on Tomcat, we will not be able to run those Java applications on a Tomcat-CF10 JVM cluster. Is this correct? IF so, what are our options?
2. J2EE Application Servers supported by Adobe for CF10
Which of these is correct?
A. This URL (http://www.adobe.com/products/coldfusion-enterprise/faq.html) states "ColdFusion 10 supports IBM® WebSphere, Oracle® WebLogic, Adobe JRun, Apache Tomcat, and JBoss."
B. This URL (http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/products/coldfusion/pdfs/cf1 0/coldfusion10-support-matrix.pdf) states:
"J2EE application servers: WebLogic Server 10.3, 11.1, WebSphere Application Server 7, ND 7 JBoss 5.1, 6.0, 7.1.0"
I *think* "A" above is wrong re. support for Adobe JRun. It does not specify a version of Apache Tomcat unless it is simply referring to the custom version the comes with CF10.
Option "B" above shows no support of Adobe JRun or 'standard' Apache Tomcat.
Thanks,
Scott

Question 1 above was answered: "No support for Java web applications under CF10's custom version of Tomcat"
Question 2: No answer yet: Is Apache Tomcat (NOT Adobe's customized version) supported for CF10 J2EE deployment? I do not see any installation instructions on how to install CF10 on Apache Tomcat 6 or 7.
Is anybody using Apache Tomcat as their J2EE app servers and, again, NOT Adobe's customized/limited version?
Thanks,
Scott

EJB transaction question in ejbCreate

I have 2 Entity EJBs participating in an relationship. Order - LineItem. I'm creating the LineItem in the the ejbPostCreate of Order.
When I encountered a duplicate key for Order in Order's ejbCreate, I was not expecting the LineItem to be created, I thought a rollback would occur.
What do I need to do to ensure a rollback occurs. And it looks like the container called ejbPostCreate even though ejbCreate threw an exception. Can I get around this?
thanks in advance!

I'll post an simple one to many relation ship example..
order table:
orderPK int
orderId int
line item table:
lineItemPK int
lineItemId int
orderId int
abstract PModel
public abstract class OrderBean implements EntityBean
public Collection getLineItems();
public void setLineItems(Collection lineItems);
publi interface LineItemLocal extends EJBLocalObject
public Integer getLineItem();
public void setLineItem(Integere value);
bean class for LineItem
public class LineItemBean implements EntityBean
public Inbteger ejbCreate(Integer lineItem)
setLineItem(lineItem);
return null;
public void ejbPostCreate(Intger lineItem)
public abstract Integer getId();
public abstract Integer setId();
//entity bean methods
public abstract class OrderBean implements EntityBean

EJB relation One to Many - ClassCastException

Hi !
I created two CMP EJB entity Client and Address. There is a One to Many relation between them.
When I deploy them on JBoss, I have no errors, and the correponding tables are created in the database. The EJB seems to work fine, but when I use a 'relation' method : myAddress.setClient(myClient) for instance. I get a ServerException.
In the log of JBoss there is :
ClassCastException : org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCCMRFieldBridge.SetInstanceValue(...)
I think I have a problem in my descriptors or JBoss configuration.
If u have an idea ...

Deafult search engine on a new tab-this thread was closed but I have a related question. Once you put the new url in, what then? Close? When tried, did not work

"deafult search engine on a new tab" - this thread was closed but I have a related question. [the word “default” is spelled as it on the thread] Once you put the new url in, what then? Close it? When tried, it did not work. The closest answer is noted here. Instructing to go to about:fig. Specifically, I installed the accuweather add=on and it took over my tab home page - the one that comes up when you click for a new tab. I didn't like it so I clicked the button to remove it and the page went blank. I searched to see out to restore the tab page, tired the reply at this page :
http://support.mozilla.org/en-US/questions/753256?s=install+search+box+on+new+tabs&r=3&as=s
But it did not work. Can some on help me? Just want to know how to make google or some page open on a new tab.
Many thanks

Thanks so much for your support. As I said I am not a professional, so I by chance saw a friend who is and this is what he suggested and it worked.
We googled for an answer and found this site: http://www.guidingtech.com/8004/have-new-tab-page-open-specific-website-firefox-chrome/
It says to Download and install Download and install''' NewTabURL''' and gives instructions on how to. Now when I open the tab it goes to my preferred search page!

PM/EAM related questions posted in PLM forum

Hi,
I was going through some of the threads available in PLM forum, but to my surprise, most of the threads posted are related to PM, which should have been posted in EAM forum. It was clearly mentioned by the moderator in one of the sticky thread [PLM-Forumsplit - Please ensure you are using the right forum|PLM-Forumsplit - Please ensure you are using the right forum;
Questions regarding Plant Maintenance (PM) or Customer Service (CS) are discussed in the Enterprise Asset Management (EAM) forum
forums - posts will be moved to the right forum.
Please ensure your are opening a new thread in the right forum
Despite the clear instructions given my the moderator, PM related questions are still posted to PLM forum and some of the active participant of EAM forum answers these questions in PLM forum. It would be nice if those threads are moved to appropriate forum, so that the relevant informations are available under one forum, also, PLM forum should be monitored regularly and inappropriate threads are to be moved to their respective forum.

I had used abuse reports for some, but numbers of such posts are many.

I hate to say this, but I often see the same thing, and I've never been able to figure out exactly what triggers selectability vs. non-selectability, but I suspect some of it has to do with tranparency flattening in particular, and possibly text wrap in cases where that comes into play. ID optimizes the PDF it creates, I think, and that might cause text, or even images, to be broken into chunks in funny ways. It occurs to me that turning off optimzing for fast web view might help in this regard.

I just got a call today that I reached my 300GB limit for the month. I called and got a pretty rude response from the security and data usage department. The guy told me in so many words that if I do not like or agree with the policy that I should feel free to find another service provider.!!! I tried to explain that we watch Netflix and XFinity on-demand alot and I was told that that can not be anywhere close to the data usage. I checked my router and watching a "super HD, dolby 5.1" TV show on Netflix will average about 5-6 GB per hour (1.6MB/s) ... sp this means that I can only watch no more than 1-2 Super HD TV shows a day via Netflix before I run out of my data usage. This seems a bit redicilous doesn't it? Maybe the TV ads about the higher speed than the competition should be accompanied with "as long as you don't use it too often" Not a good experience ...

Online Help Related Questions

Hi
FYI there is no longer a dedicated place on Microsoft.com for online help related questions.
We are told that VS General (here) is the best place for help questions.
Note that these sites are a good place to get help on help (Microsoft and MVP presence):
http://groups.yahoo.com/group/hatt/ -- for WinHelp & HTML Help & general help discussion
http://tech.groups.yahoo.com/group/MSHelpViewer/ -- For HelpViewer help (VS 2010/2012 help; Windows 8 help)
http://tech.groups.yahoo.com/group/MSHelp2/ -- For MS Help 2.x help (VS 2002/2003/2005/2008 help)
Feel free to ask questions on this thread if you need to. At least then we can find your post.
You can also email the VS/MSDN help team directly -- [email protected]
Please let them know how you feel about the lack of support for Online Help in the forums.

Actually, we cannot (at least anymore) directly email the team. I tried and got a reject from the mail server. So, I'm going to post here so I can feel better knowing I said something and then I can get back to programming :-)
Ok, I’ve been developing Windows apps since Win 3.1 (yeah, a long time) and have always admired the Microsoft attitude towards Developers and it’s desire to educate and empower R&D.
So, I’m wondering what’s going on? Why am I being asked to have an account to develop anything for MY own PC? Why am I being asked for my Microsoft account password, repeatedly, when I’m just looking up documentation on UserControl or C3 keywords…
repeatedly? This is nothing short of annoying and it gives me pause and concern about the ecosystem. Is the plan to lock down programmer’s capabilities, knowledge and tools?
I’m involved in the TAP program for Windows 10 and have voiced concerns in the same category with regard to installation and deployment of Universal Apps. Security is not a reasonable excuse. Some of us love to program and actually
control their PCs. We are not planning to sell everything we write on the Windows Store. What happened to programming something cool for your home network or just for friends? We need, and used to have, Microsoft’s support in doing
this sort of thing. Documentation and tools are more important now than ever. I’m saddened to see the direction things are heading…
If there is a sane reason I’m being badgered to ‘log in’ to read .NET documentation every hour, please share. If not, please consider lobbying to get things back on track.
Thanks

Nonunique ejb-relation-name

hi all,
i have a bean that has 2 seperate
many-many cmrs to the same bean.
the workbench is creating 2
ejb-relations with the same name.
in any case, weblogic.ejbc is giving
me an error that that ejb-relation-name
must be unique? i like having the
workbench maintain the ejb-jar.xml
file and so i ask if there is anyway to
bypass this other defining one of the
relationships by amending the descriptors?
thanks,
sean

just to be clear, this is not a composite.
the situation is EJBFoo has 2 many-many
cmrs to EJBBar. my original post wasn't
quite clear.
thanks.

Button, or other panel related question

so, if any of you have read my previous topic about painting rectangles in a panel, that worked great, but now i need to mkae those rectangles components so that when someone hovers over it or clicks on it it displays information at a certain area. I know how to make listeners and how to add buttons in a panel, BUT how do I add buttons at a specific coordinate. This program graphs data on a specific scale and therefore adding a button in the approximate area using a grid layout will not be good enough. Is there anyway for me to place the the button/component/object at the extact location that I want?
thanks in advance

In future GUI related questions should be posted in the appropriate GUI forum (likely Swing).
