Technical Article on Service-oriented Integration Using JBI Posted

I've just posted an article on the open-esb site about using JBI for what we have come to call service-oriented integration: enterprise integration atop a SOA fabric. The article includes an example of a simple adapter pattern implementation that includes message transformation and protocol hopping.
See https://open-esb.dev.java.net/ for the PDF download.

At last!!
Finally an article about the real JBI and what JBI is all about. I don't know what's going on with people's understanding of JBI.
At JavaOne, I remember one of the expert group, from Oracle I think, proudly claiming that JBI will be one of the core architectures that companies will be delivering their integration business upon. Now I wonder where Oracle's, SAP's and IONA's contributions are so far. Oracle for example really contributed to JSR 208 by marketing and implementing SCA.
Although in early stages, I think open source implementations are missing the point as well. Using open source implementation X, I couldn't see a scenario that shows the power of the concept, while implementation Y just did not like service units, service connections and link types, then tried to invent its own configuration and routing descriptors, wasting very valuable time.
Anyway, may be one just have to wait and see!!
Thanks Ron for such contribution.

Why java is called pure object oriented.

i know that java is called as pure object oriented language.
why it is called so even though it has primitive datatypes and also it doesnot support multiple inheritance completely. it only supports in the case of interfaces but not in the case of classes. then why it is called pure object oriented.

Its because you cannot write an executable java program without creating an object. Well, you can:
public class a
public static void main( String a[] )
}In contrary to C++, there can be no variables or functions in the wild (outside a class).
You can not create an executable java program without creating a class (but not forcibly its instance, an object.)
The "pure object oriented" wording in this sense has not really much importance, it is rather a marketing ploy.

Why java is called as true object oriented language?

HI Friends,
Though few oops concepts is not supported , why java is called as truly object oriented language and C++ as not a purely object oriented language???? Please, if any one know , give me the answer.
Thanks to all.

few oops concepts is not supportedwhich concepts?
as far as i know...to be OO, you must supports
encapsulation, abstraction, inheritancxe, composition (aggretration, et all) and polymorphism. Java supports all those comcept..now..Java is a hybrid due to what Jverd has pointed out.
the only pure OO language that i know of is SmallTalk. they have Meta class that can create Class object. and all their primitaives are object.
C# comes close, but their Class are not object.

Domain Object and Service oriented pattern

We have J2EE based application with following components, we are facing some issues with existing system.
Current System : We have J2EE based application. The following is the flow.
Client Layer [including JSP, Struts ] action classes  Delegates  Session fa�ade [Session bean]  DAO EJBDAO  EJB. We use CMP, xDoclets , JBOSS.
1.     Our Domain objects are heavy. I know they are suppose to be coarse objects but they take more time in loading. Also, we noticed one thing that lot of methods are called during Domain Object creation process and it takes lot of time in loading. Actually, we dont really know what is happening as we are using CMPs.
Question :
-     Any input on what can be done to avoid Domain object excessive loading time.
-     Anyone can share there experiences with Domain objects. Are you facing issues related with performance.
-     We dont use DTO, we pass domain objects between. Do you see any problem in doing that.
2.     Currently, our system was used by one single front end or lets say we have only one client but soon we will have more clients using it.
Question :
-     What should be our design approach. How can we make our system more like service oriented. If the two clients demand different business logic then how it will be handled. Business logic common to all the clients will be handled by which layer and business logic specific to client will be handles by which layer.
-     Please suggest based on our existing infrastructure. We don�t want to use SOAP or cannot make drastic changes to our flow.
We have domain and services in the same package and we are doing the refactoring of code, your inputs will be valuable.
Thanks

What type of logger do you use and what is the loger-level during production?
If it is log4j set the logger to level INFO or WARN.
This might sound trivia but can make a difference between 20seconds and 500 ms.

SODA - Service Oriented Integration of Medical Devices in Hospitals

In this thread I will write about my dissertation project. It addresses the problem of the integration of medical devices with their proprietary interfaces and data models into the existing hospitals´ IT infrastructure.
Interoperability is an almost non-existent feature of medical devices. The consequences of non-interoperable devices in hospitals are manifold. Medical data produced by devices cannot be directly integrated into hospital information systems for medical documentation. Thus, important data will be lost and examinations have to be repeated if required information is not available due to incomplete documentation. In addition, the documentation quality is affected by human errors due to manual nonelectronic steps and media discontinuities. Another example is maintenance. Medical devices have to be maintained at regular intervals. Thus, an inventory of all devices, their status and maintenance intervals is needed for generating a maintenance manual. Currently there is usually no possibility for automatically getting a detailed inventory of all medical devices in a hospital (or section of a hospital).
The market size in conjunction with a multitude of companies and products (the DIMDI information system contains data about 60,000 medical devices) results in challenges concerning interoperability due to different proprietary hard- and software interfaces, data structures and semantical interpretations. Initiatives like IHE (Integrating the Healthcare Enterprise) are trying to push standardization in the medical sector. However u2013 as mentioned above - the current situation is still unsatisfying and increasingly getting worse due to the continuously growing number of medical devices and associated interfaces.
A promising approach for overcoming interoperability issues is the service oriented device integration, also known as SODA (Service Oriented Device Architecture). The basic concept is the encapsulation of devices as services, analogous to enterprise services in service oriented architectures (SOA). An enterprise service is a software component that offers a business functionality on a highly semantical level by specifying the interface in a standardized way (e.g. by the Webservice Description Language u2013 WSDL). Highly semantical level especially means, that a service is self-descriptive in a way that it can be consumed dynamically and loosely coupled by other components with a consistent understanding of shared data. In the medical domain a device service for instance could offer functionality for measuring the current blood pressure of a patient. Based on such basic services more complex services (like a patient monitoring system) can be realized.
The main advantage of the service oriented approach is that the manufacturer-specific device interface does not have to be known by the service consumer and by the programmer respectively, as it is encapsulated by a standardized service interface. This enables the extension of IT supported medical processes by devices, e.g. by using the Business Process Execution Language (BPEL). In addition new functionalities could be added to the device service that are logically related to the device but not offered by the device itself (e.g. tracking & tracing functionalities); so the device service can be considered as a virtual device. Therefore software maintenance will become easier, because the service interface remains unchanged in case of a device exchange or device interface changes. In my dissertation project I will explore the advantages and obstacles of the SODA concept in comparison to existing approaches for integrating medical devices in hospitals.
The SODA approach is in accordance with the SAP Enterprise SOA (ESOA) strategy. For instance, the scope of the Healthcare Community Definition Group is to further enhance the Enterprise Services (ES) Bundles Patient Administration and Medical Activities, Patient Billing and Invoicing and to define a new ES Bundle on Medical Documentation. SODA projects define services for devices. These services can use or combined with Enterprise Services, e.g., for Patient Administration. In the EU funded project SOCRADES, SAP Research explores the SODA approach in other domains, especially industrial automation.

Hmm, perhaps your other discovery settings are configured that it'll get the OOB OU because you're OOB OU is under some other OU that's configured to be discovered and you have the recursive and group settings turned on, CHECK this first.
Remove the OOB from your discovery. For testing purposes, remove (delete) one or more machine objects from the ConfigMgr console, wait a while and then run the AD System Discovery again and check what object gets there. AD system discovery shouldn't look
objects from other OUs than the ones you've specified in the discovery settings.
I'm not that familiar with vPro, so the behavior you're seeing might well be the default, but I doubt that.. Doen't make sense that you control your computer objects.
For more information you could also post adsysdis.log from the configmgr server.

Why JNDI is called an Interface?

Why JNDI is called as Java Naming and Directory Interface, question is why
interface ? when it is not a interface ?

It is an interface because it is defined as an abstract set of APIs, not actually implementation. The actually implementation is done by service providers.
Defining an abstract set of APIs without actually implementation can isolate the implemenation of service provide and client application code, thus make them more independently from each other. i.e, a client application would not need to know what changes made by any particular vendor.
Hope this helps.

HT1245 Why does my caller I.D. photos show as a small thumbnail in the upper right corner and not full screen? I have used both photos I have synced and photos I have taken, yet others have full screen photo I.D.'s.

Why does my caller I.D. photos show as a small thumbnail in the upper right corner and not full screen? I have used both photos I have synced and photos I have taken, yet others have full screen photo I.D.'s. I have looked onlime at several threads and there are no real answers as to what I need to do or am doing wrong.

I am also having this issue.
I've just spoken to someone in the Apple Support Centre who advised me that since the product is in beta, he is unable to assist. I wanted to find out whether someone was able to delete the data for me, or 'reset' the photos app somehow. This apparently cannot be done. He suggested I provide feedback via the feedback page, which I will do, but to be honest doesn't fill me with a lot of confidence in the issue being fixed.
I also deactivated the service and waited the 30 days for the pictures to be deleted - this should have been completed in mid-January. Instead, my iCloud.com Photos page is now showing the photos that should have been deleted as grey squares, just as you described. I am also unable to delete these photos; every time I try, I get the same message about a server error.
I am also unable to disable the service by enabling and then disabling it on my iPhone. Each time I have tried this it hangs on uploading for several hours, with the progress bar not moving at all. When I disable it on my iPhone, the web app remains unchanged.
If anyone has had this issue and has managed to fix it, PLEASE share your wisdom. I am out of patience!

OSB - rethrow error to calling service

Hi,
I am facing wierd issue in OSB.
I have a BPEL process which invokes my OSB proxy service.
The business service of my OSB calls an external webservice.
Whenever my external websrvice sends an error, my OSB returns the error to my calling process BPEL.
I havent implemented any explicit Error Handling in the process.
But I am not sure why, whenevr my OSB sends an error, my BPEL process instance doesnot appear.
It is taking lot of time forthe error to come back to BPLE from OSB.
Please suggest some solution

OSB will rethrow the error to the calling service if proper error handling has not been done in OSB. You may be interested in -

Why ProfileAdapterRepository is called so? where is the Adapter in it?

Does anyone know why ProfileAdapterRepository is called so. You won't see the word Adapter in any other repository name. Do we have an implementation of adapter pattern in ProfileRepository?

Sanju,
in ATG, you can maintain separate profile repositories for external and internal users. There are separate repository definition files for internal users and external users. The external profiles are stored in the /atg/userprofiling/ProfileAdapterRepository, defined by the userProfile.xml file located in <ATG10dir>\DPS\config\profile.jar. Internal profiles are stored in the /atg/userprofiling/InternalProfileRepository, defined by the internalUserProfile.xml file in <ATG10dir>\DPS\InternalUsers\config\config.jar.
Other repositories will not be having different categories within them. for example for inventory we do not have sub types and hence the generic term InventoryRepository. In case of profile to identify whether it is an external profile repository or internal profile repository we have additional attribute attached to the name of the repository.
Also since Repository concept is basically built on Adapter design pattern we see this Adapter in ProfileAdapterRepository instead of something like ExternalProfileRepository

DocNum in a Call Service

Hi, I have an Addon that modifies some user fields in a Call Service document, this Addon creates the call service document with a button that i draw in the form and then actualizes the call service in some user fields. The problem presents when I have to create a new call service document, in the DocNum native textbox appears the same number that the last Call Service and I can't create a new document. It only fixes if I close SBO and start a new session of SBO.
Does anybody know why it is happen?, how to solve this bug?.
Thanks Regards.

Hi,
You may consume external service via JNDI
Context context = new InitialContext();
<JNDI OBJECT> local = (<CAST JNDI OBJECT>)context.lookup("<JNDI OBJECT>");
//Call the method
If you are using CE 7.11, go to NWA -> Problem Management -> JNDI browser > ..... -> ObjectName for <JNDI OBJECT>

Why cant I call a getResultSet method more than 1

Why cant I call the getRSS method more than 1 time from my page?
I have a class called methods class, here is the code:
public class methodsClass {
    public java.sql.Connection objConn = null;
    public String query = null;
    public java.sql.PreparedStatement statement = null;
    public java.sql.ResultSet objRS = null;
    /** Creates a new instance of methodsClass */
    public methodsClass() {}
     public ResultSet getRSS(String sql)
        String strSQL = sql;
        try
            Class.forName("oracle.jdbc.driver.OracleDriver");
            objConn = java.sql.DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:CCD","system", "Abcd1234");
            statement = objConn.prepareStatement(strSQL,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
            objRS = statement.executeQuery();
        catch (Exception e)
            System.err.println("Error in getRSS method");
            e.printStackTrace();
        return objRS;
    public void killConn()
        try
                objRS.close();
                System.out.println("Resultset is closed");
                statement.close();
                System.out.println("Statement is closed");
                objConn.close();
                System.out.println("Connection is closed");
            catch(Exception e)
            System.err.print("Unable to kill all objects");
            e.printStackTrace();
//END OF CLASS***************************************** I call the method from the following jsp:
<%
String eqCat = "Tracked Vehicle";
String strSQL = "SELECT DISTINCT * FROM robert WHERE eqcategory = '"+eqCat+"'";
methodsClass mc = new methodsClass();
ResultSet objRS = mc.getRSS(strSQL);
java.lang.System.out.println(strSQL);
%>
     <select name="selectBox">
     <% while(objRS.next()){
         out.println("<option value='"+objRS.getString("eqtype")+"'>"+objRS.getString("eqtype")+"</option>");
           mc.killConn();
%> The above works fine.
If I try to call the getRSS function again on this page I get the following error:javax.servlet.ServletException: Exhausted Resultset
I tried to call it like so:
newNameSQL = "Select * from robert where eqtypes = 'someVariable'";
newNameRS = mc.getRSS(strSQL);
<%=newNameRSS.getString("something");%>I cant understand why I get this error, I am closing the rs,conn and statement in the killConn method.
TIA!

I did that but still the same error. The problem is when I attempt to open up another resultset on the same page I get the Exhausted ResultSet error. I have even eliminated the class file altogether by doing this:
String eqCat = "Tracked Vehicle";
String strSQL = "SELECT DISTINCT eqtype FROM robert WHERE eqcategory = '"+eqCat+"'";
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection objConn = java.sql.DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:CCD","system", "Abcd1234");
PreparedStatement statement = objConn.prepareStatement(strSQL,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
ResultSet objRS = statement.executeQuery();
System.out.println(strSQL);
//The above works fine and then below I add this and the error comes back
     <select name="cs_popup_name_1" onchange="CSURLPopupShow(/*CMP*/'cs_form_name_1', /*CMP*/'cs_popup_name_1', 'Main');">
     <% while(objRS.next()){
        String eq = objRS.getString("eqtype");
         out.println("<option value='"+eq+"'>"+eq+"</option>");
objRS.close();
objConn.close();
statement = null;
strSQL = null;
strSQL = "SELECT * FROM robert";
Class.forName("oracle.jdbc.driver.OracleDriver");
objConn = java.sql.DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:CCD","system", "Abcd1234");
statement = objConn.prepareStatement(strSQL,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
ResultSet rs = statement.executeQuery();
System.out.println(strSQL);
//If I leave the field below commented out I get no errors, but if I comment it out I get the error

File Based logging: Control file name based on calling service

In the file logging, I need to change the "Prefix" and "Suffix" that I can type in, from page "FILE Transport Configuration" while creating
business service with transfort: File. I need to be able to supply these values for the file name from proxy service activity.
I am creating as logging proxy service which will be called from all the other proxy services. I am planning to use logging to File System based on
BS for achieving this. I need to be able to create a new file with name that corresponds to the calling service. How can I achieve this?
Also this service should be able to turn logging on or off based on the calling service. I should be able to turn off the logging completely or
turn off the logging only for few services.
What is the best way to achieve this?

HI
That means your file name would be decided at run time . so u can use adapter specific mesage attributes in ur communication channel

Since you have already done some sort of reset on your Airport Express, you might as well make sure it was a "hard reset" - follow the instructions for a hard reset found at:
http://docs.info.apple.com/article.html?artnum=108044
Since your Mac is running Leopard, you need to configure the Airport Express using the Airport Utility found in the Applictions->Utilities folder. You cannot install the old software that was supplied on the CD you got with the Airport Express.
In future - if you do something bad with network settings on your Mac, do NOT try to fix it with the Airport Utility. The Airport Utility is only used to configure the Airport Express - and since the problem you have created is on the Mac and not the Airport Express, there is no need to be using the Airport Utility and especially there is no need to be resetting the Airport Express.
