Common Utility Project for 2 applications in 2 different Tracks

I have 2 applications to be deployed in two different landscapes. So I defined two tracks for them; now these 2 application use common utility projects (Java project and Library project). Here is how it looks,
Scenario:
App1EJB
App1Web
App1EAR
App2EJB
App2Web
App2EAR
Util1 (Common to both App1 and App2)
Util2 (Common to both App1 and App2)
My question is,
1) So should I define 3 Tracks here?
     Track1 (App1)
     Track2 (App2)
     Track3 (Utilities)
2) Is this a good approach?
3) How will I define usage dependency across Tracks
4) How to do the deployment (always deploy Track3 before deploying Track1 or Track2?)
Please let me know.
Thanks,
Deepak

Hi Deepak,
First of all: how many SCA's did you define?
I would have 3 SCA's, one for the APP1* applications (APP1.SCA), one for the APP2* applications (APP2.SCA) and one for the utility aplications (UTILS.SCA).
Each of these SCA's will have their own track. For the first 2 SCA's (APP*.SCA) it is clear why (different landscape). I would have a separate track for the UTILS.SCA, because I would like to use only approved utilities.
Make the UTILS.SCA known in the other 2 tracks as dependent SCA of the APP.SCA's. Using the public parts and used DC's mechanism, you are able to use the utillities in your APP DC's.
Using transport connections between track3 towards track1 and track2 ables you to have the latest approved utillities avaliable in track1 and track2.
Regarding the deployment, there is the question of how you are using the utillites: as services by themselfs on the Java runtime or included in the separate deployable ear-files. In the first case there is only one version of UTILS.SCA avaliable and used by both APP1.EAR and APP2.EAR. In the second case you have 2 versions (included in the ear-files), which makes updates of UTILS.SCA a redeployment of both APP1.EAR and APP2.EAR necessary.
Is this a good approach? Using 3 tracks makes it harder to test the utillities using the APP1.EAR or APP2.EAR. You need some test-features located in the UTILS.SCA. But you are at least sure you have only approved utillities in your ear-files.
Hope this helps a little.

Alain

Common business action for Email/FTP transports behaving differently

Hi B2B Gurus,
We have configured a common business action for incoming documents for different transports (Email and FTP). Since the exchange protocol is "Custom document over generic exchange" and the payload is the same for the 2 protocols, we had to create a common business action as the Document definition (identification criteria) is the same. We have ofcourse created separate agreements with separate DCs but the same business action.
In the above scenario, it works fine for all well formed documents (XML). We are observing that it it throwing the "unable to identify the document protocol" error when the invalid payload is sent through Email protocol but is allowing the document into Oracle B2B for FTP. We are using Oracle 10g and are on the latest patch.
Can you pls let us know if this is the behaviour expected? Shouldn;t it be the same as the business action is the same ? Is transport making a difference? pls let us know asap as this is blocking some test scenarios as we have to go live soon.
Regards
Kavitha

Hi Kavitha,
Do you mean to say that the agreement is identified based on the "identification criteria" for Email protocol and not on the Email ids?In case of EMail transport, Email ID's are used for partner identification but for XML document identification, only XPATH is used.
Is there anything that can be changed in our configuration to allow invalid documents pass thru b2B so that the validation can be handled by our backend?Treat XML files like Flat files and keep validation disabled and then invalid documents can also be passed.
In this case, we also see that the idenfication criteria (XPATH) value is coming fine but the XML is not well formed.If you have configured B2B for custom XML and incoming XML is malformed then anyhow it will fail in EMail transport as document it self will not be parsed and hence XPATH can not be applied. As I mentioned above, if you still want to accept this doc, configure B2B for custom flat file instead of custom XML.

Common utility library for multiple websites (PHP/Dreamweaver)?

I am working on several PHP-based websites, and would like to
use the same utilities in
them all. The local directories for the individual websites
are all subdirectories of the
website D: Websites.
I could fairly readily put the utilities in a website D:
Websites/Utilities, put a copy of
this directory in the root directory of each website on the
server, and tell PHP to load
the utilities from the correct place, according to whether
I'm running on the local or the
remote server, but Dreamweaver does not seem to have any
provision which would allow me to
use it to upload new versions of the utilities from the
Common local area to the remote
servers. Is there any way to do this, or will I have to write
a special PHP utility?

Dreamweaver is site based, and it works on the assumption
that the site
folder is the server root. This was appropriate in the early
days of
Dreamweaver when sites were created with static HTML and
everything
needed to be in the server root. It's less convenient when
building
dynamic sites that rely on libraries located outside the
server root.
Several beta testers have urged Adobe to improve the site
definition
setup so that libraries outside the server root can be easily
maintained
and uploaded from within Dreamweaver. Unfortunately, Adobe
has not
changed the way sites are defined to meet this increasingly
common
scenario. The more people who submit formal requests for this
to happen,
the more likely Adobe is to respond. Submit a feature request
here:

Error finding project for application

Hi Seb,
thank you for your answer.
Unfortunatelly, I still have problems with this.
Here is my step-by-step install & config procedure:
0. installed all products
1. configured all products
2. logged as admin in user management console and created new user (let's call him "superuser")
3. logged as superuser in user management console and created new project
4. created new planning datasource
5. created dimensions and application in EPMA
6. deploy this app
Here I get this error.
Could you (or anyone else) please describe your install & config process? I think I'm missing some config steps or I'm doing it in wrong order.
Thanks!
Vlado
Edit:
I found another error message in BPMA.log:
Application does not exist by this Id

How to give Common Background color for all JPanels in My Swing application

Hi All,
I am developing a swing application using The Swing Application Framework(SAF)(JSR 296). I this application i have multiple JPanel's embedded in a JTabbedPane. In this way i have three JTabbedPane embedded in a JFrame.
Now is there any way to set a common background color for the all the JPanel's available in the application??
I have tried using UIManager.put("Panel.background",new Color.PINK);. But it did not work.
Also let me know if SAF has some inbuilt method or way to do this.
Your inputs are valuable.
Thanks in Advance,

It is not the fault of NetBeans' GUI builder, JPanels are opaque by default, I mean whether you use Netbeans or not.Thank you!
I stand corrected (which is short for +"I jumped red-eyed on my feet and rushed to create an SSCCE to demonstrate that JPanels are... mmm... oh well, they are opaque by default... ;-[]"+)
NetBeans's definitely innocent then, and indeed using it would be an advantage (ctrl-click all JPanels in a form and edit the common opaque property to false) over manually coding
To handle this it would be better idea to make a subclass of JPanel and override isOpaque() to return false. Then use this 'Trasparent Panel' for all the panels where ever transparency is required.I beg to differ. From a design standpoint, I'd find it terrible (in the pejorative sense of the word) to design a subclass to inconsistently override a getter whereas the standard API already exposes the property (both get and set) for what it's meant: specify whether the panel is opaque.
Leveraging this subclass would mean changing all lines where a would-be-transparent JPanel is currently instantiated, and instantiate the subclass instead.
If you're editing all such lines anyway, you might as well change the explicit new JPanel() for a call to a factory method createTransparentJPanel(); this latter could, at the programmer's discretion, implement transparency whichever way makes the programmer's life easier (subclass if he pleases, although that makes me shudder, or simply call thePanel.setOpaque(false) before returning the panel). That way the "transparency" code is centralized in a single easy to maintain location.
I had to read the code for that latter's UI classes to find out the keys to use (+Panel.background+, Label.foreground, etc.), as I happened to not find this info in an authoritative document - I see that you seem to know thoses keys, may I ask you where you got them from?
One of best utilities I got from this forum, written by camickr makes getting these keys and their values very easy. You can get it from his blog [(->link)|http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/]
Definitely. I bit a pair of knucles off when discovered it monthes after cumbersomely traversing the BasicL&F code...
Still, it is a matter-of-fact approach (and this time I don't mean that to sound pejorative), that works if you can test the result for a given JDK version and L&F, but doesn't guarantee that these keys are there to stand - an observation, but not a specification.
Thanks TBM for highlighting this blog entry, that's the best keys list device I have found so far, but the questions still holds as to what specifies the keys.

Xmlbean facet for utility project

Hi, I created a utility project (I only have schema for this project.) and have Apache XMLBeans added. but I don't see Apache XMLBeans showup in Project Explorer. I only see JRE System Library. And I got error "org.apache can't be resolved to a type".
Also there is a XMLBeans Builder problem "Unable to locate a tools.jar inside a 1.5 JDK installation. A 1.5 JDK must be added to the set of installed JREs to support the XMLBeans interface extension feature where the custom interface is processed as a Java source file (restart required)."
My OEPE runs on JRE1.6. How to fix these? Thanks!

ITunes Connect - New Application Company Name common or unique for each a

We have our first couple of applications ready to go. But I am a little confused with the iTunes connect meaning of 'Company Name' - when adding an application.
We are developing audio / spoken word applications for several companies and wanted to show each application in the store as the application title and the authors name as the company name.
Does anyone know if the company name you enter the first time in iTunes connect is common for all applications you submit - or can it be different for each application?
Thanks

It is common for all apps that you submit. You don't get the option of inputting a different one when you create others.
You *can not* change this (or at least not without calling support, but even that hasn't worked yet).

Common Supplier master database for Custom Applications and Oracle Financia

Hi,
We would like to build a custom applications (Multiple) for our organization core business operations using .NET on the database which is being used by Oracle financials R12.1.1. These custom applications are going to have its own application servers. BUT the database is common for both custom applications and oracle financials. This database is going to house on the Oracle RAC.
We would like to have a common supplier master for both custom applications and Oracle payables. Could you please help me with below questions?
1. How to create/Update/Query the supplier records in the supplier master tables provided by Oracle financials using custom applications?
2. How can we store the additional data elements needed by each custom application? We can't use the DFF on the supplier tables as the data elements for each custom application is going to be different. even though they use same supplier.
3. We might have multiple supplier with same name but different FEIN/SSN numbers. As per the design Oracle financials doesn't allow the same supplier name entered multiple times even though FEIN/SSN number is different. How can we workaround this limitation?
Thanks,

Hi,
Please find my comments below:
1. How to create/Update/Query the supplier records in the supplier master tables provided by Oracle financials using custom applications?
A: You may use Supplier Open interface and Sites Interface to Create the Supplier Records. I don't think there is any API to update Supplier Info. Since both the applications exist on same database, I think you can query the Vendor tables from Custom applications also.
2. How can we store the additional data elements needed by each custom application? We can't use the DFF on the supplier tables as the data elements for each custom application is going to be different. even though they use same supplier.
A. Designing different tables depending on Custom Application ID and Vendor ID seems to be the only option.
3. We might have multiple supplier with same name but different FEIN/SSN numbers. As per the design Oracle financials doesn't allow the same supplier name entered multiple times even though FEIN/SSN number is different. How can we workaround this limitation?
A.One alternative is to create a single supplier with each FEIN/SSN number as site. Second one is to create Supplier Name concatenated with FEIN/SSN numbers as different suppliers and store the actual name in some DFF or other field. Standard functionality won't allow such duplication (Cannot Create Supplier/Employee With The Same Name Of Existing Supplier [ID 743430.1]).
Hope it helps.

Images do not show up in web project in J2EE application[/b]

I have cretead a web project in which i hava a servlet and couple of jsp's and some java util classes. This application gets the data from the database and displays it on a screen. Beside displaying, this app also transform the xml document to html using. I have the the XSL Stlesheet under Web Content along with all the jsp's.
I also have images folder under Web-Content which has all the images for this application. When i run the application using Oracle 10g application server within Jdev, the application cannot find the images or the xsl stylesheet. Relative path to images in jsp is /images/someimage.gif while relative path to xsl is /some.xsl. For some reason it cannot find the images or the xsl when the application runs or deployed in OC4J container. Any help on this will be appreciated.
I have checked the path in reference to the context-root and it seems to be correct.

Relative path to images in jsp is /images/someimage.gif while relative path to xsl is /some.xsl.
Is the images dir under the jsp dir?
If the images dir and the jsp dir are at the same level, the relative path would be ../images/someimage.gif

Hi Lindalnci
i have already tried this tutorial and in my post i have defined first way to do using this procedure.
in that case i have got following exception as i have mentioned above
org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection

Why Dev Guide says "create a separate project for each ADF task flow ..."

Hi,
We have a BPM process application which is having a few human tasks. The form for each of the human tasks is similar. We’d like to be able to share some page fragments or code between them and create single web application to handle all the human tasks for this BPM process application. Then I found the following in the Oracle document “Developer’s Guide for Oracle SOA Suite 11g Release 1 (11.1.1.4.0)”:
“If the SOA composite contains multiple human tasks, create a separate project for each ADF task flow associated with each human task.”
I wonder if we have to do that and if so, what is the reason.
Do you have any clue? Please help.
Thanks a lot,
Helen

Hi Helen
1. I do not know the reason why they mentioned like separate project for each human task. NO, this is not required and we can have just one UI Project like MyTaskForms and have all the JSPs in this same project for each Human Task.
2. On our side, we have like 10 Human Tasks, all using the same Payload. So we have 10 .task file. For the very first .task file, we used Auto Generate Project and gave project name like OurAppTaskForms. The reason we did this is, so that it adds all the required dependent libraries, tag libs etc properly. For all remaining 9 .tasks file, we did NOT use auto generate. Instead we used standard New -> JSF From Human Task and select one task at a time and follow the steps. These steps are covered in the online documentation. At the end in our BPM App, we have just one UI Project with all the 10 screens.
3. ALSO, all the 10 screens have some common data. This we put in a reusable JSF Fragment page. And associated a custom Managed Bean for this to set and get values from this fragment and also some Actions for some buttons in the JSF. Then we included this JSF in each taskform jsf file, uisng the include tag. We added this include tag, somewhere in the top. So all screens share common jsf fragment page.
4. We can refine the above stuff further. As per above, we still have 10 JSF screens for each one of the 10 .tasks. Ofcourse all these 10 jsf have same common jsf fragment. BUT instead of 10 individual jsf screens, we can have only ONE Jsf screen also. Refer online docs for the details. The challenging part is, since we have only one jsf, there may be some bussiness stuff, validatoin stuff to take care of in custom ValidationCallback Handler classes. Say for Task1, we had to show some buttons, but NOT for Task2. So we had to handle this logic. Also in validation call back, we can always get each Tasks, title also. So we can workaround this issue also. We are in the process of doing this right now. But first 3, we already did and they are working fine.
My personal suggestion is first go with single jsf fragment and include in all tasks jsp files. Any changes to common elements need to make only in one place i.e fragment page.
Thanks

Where can I download example projects for Kinect for Windows v2?

so for a project I am working on regarding the Kinect v2 I had initially planned on using Matlab to code for the Kinect. However, the code on the Mathworks website regarding the Kinect seems to only work with the Kinect v1 and I cannot figure out how to
get the v2 to work with Matlab. Now I am in the predicament that I need to use Visual Studio and have never done so before. To make matters worse, all of the guides I can find about programming for the Kinect assume you are very familiar with Visual Studio
so I get lost before I can even get through the setup (I have no idea what kind of project is best for Kinect, though I intend to use C# as my programming language, or where these settings they are changing are located). If I could just find an example project
file to download I feel like it would help me a lot, but I cannot seem to find one.
So my question is thus, is there a place where we can download project files for Visual Studio? I really just need to see what one looks like and what kind of settings it runs on so I know where to get started. It would be awesome if the project file involved
overlaying the skeletal model on top of people in real time as well.
If this is not possible, even a video that explains in depth how to go about using visual studio and the Kinect at the same time would be greatly appreciate, or a workaround to get Matlab to work with the Kinect v2.

Hi Jicnon,
When you download and install the Kinect SDK, it comes with the Kinect SDK Browser application. This applicaiton is a web based application that contains a bunch of sample projects for getting started with Kinect for windows programming.
There is also the jumpstart videos here:
https://social.msdn.microsoft.com/Forums/en-US/8428671a-781c-4850-a56d-905ab28f8f8f/mva-jump-start-programming-kinect-for-windows-v2-videos?forum=kinectv2sdk
To get to the SDK Browswer app just hit the windows button type in "Kinect SDK" and this application should appear.
There are also some samples in Kinect Common Bridge and a dicussion on using Matlab here:

Security Error while trying to deploy my project to the application server from jDeve

Dear All,
I'm trying to deploy my project to the application server from jDeveloer but i got the following error :
Invoking Oracle9iAS admin tool...
D:\Oracle\OUIHome\jdk\jre\bin\javaw.exe -jar D:\Oracle\OUIHome\j2ee\home\admin.jar ormi://M-AMIN:3101/ admin **** -deploy -file D:\Oracle\OUIHome\jdev\mywork\Portal\UserManager\userRegister.ear -deploymentName userRegister
Security error: This operation was denied. The admin.jar utility can not be used to perform operations against OPMN managed OC4J instnaces. Please use Enterprise Manager or dcmctl instead. Refer to the Oracle9iAS Admin Guide or the OC4J User's Guide for more details.
Exit status of Oracle9iAS admin tool (-deploy): 1
#### Deployment incomplete. #### Sep 10, 2002 4:16:53 PM
Any help will be appreciated
Regards,
Mohammed Amin

In JDev 9.0.2, to deploy to the full 9iAS server (instead of just Oracle9iAS Containers for J2EE [OC4J]), you have to use Enterprise Manager or DCM to deploy your application.
In JDev 9.0.3 Preview, there is a way to have JDev perform a deployment via DCM for you, if you install a DCM Servlet into 9iAS that comes with JDeveloper.
By JDev 9.0.3 Production, if you also use Oracle9iAS 9.0.3 Production, it should be possible to deploy to iAS 9.0.3 out-of-the-box.

Seperate Project for EF

I am following a example on creating a ASP web app using the entity framework, but I have a database already created I would like to access.
I would like to use the entity framework classes in a couple of projects. Is it considered a good practice to put the entity framework. code in a separate project?
Do you put all the controller code in the entity framework project or in the web portion of the project?
When creating the project for the entity framework would I still use a web project template or would I use a DLL template?
Thanks in advance.

Hello Kazinski
>>Is it considered a good practice to put the entity framework. code in a separate project?
Personally, I would like do that puts data access code to a separate project which would make us easy to manage it.
>>Do you put all the controller code in the entity framework project or in the web portion of the project?
I do not quite understand what you mean about the controller code, if you mean business code, I would put them into a separate layer which we could call it business layer. It is not recommended to put business code and data access part code together.
>>When creating the project for the entity framework would I still use a web project template or would I use a DLL template?
If you are creating a MVC project, this project has already helped us constructed a separated layer. If it is just a common web application, you could create a class library project for your Entity Framework, and note do not forget to copy the connection
string in your class library project to your web application or it would throw an exception.
