Service Registry: why do i need two bindings (wsdlDeployment and endPoint)

based on the technical note of Clemens Utschig "Enabling a Dynamic, Reusable SOA with Oracle BPEL Process Manager and Oracle Service Registry" i have one question:
why do i need two bindings (wsdlDeployment and endPoint) in my service in the service registry. if i only define the wsdlDeployment if get this messages:
<2006-12-07 09:39:02,559> <FATAL> <default.collaxa.cube.ws> no endpoint found - nothing to adjust
<2006-12-07 09:39:02,559> <WARN> <default.collaxa.cube.ws> Could not lookup base endpoint!
the problem of defining two bindings is that the url to my partner is redundant.

Hi Clemens,
The UDDI Version 3.0.2 Specification (http://www.uddi.org/pubs/uddi_v3.htm) say this:
B.1.2 Using the "wsdlDeployment" value
Instead of directly providing the network address in the accessPoint, it is occasionally useful or necessary to provide this information through indirect means. One common scenario for such a behavior is when the accessPoint is embedded within a WSDL file. In such a scenario, the UDDI accessPoint contains the address of the WSDL file, and the client then must retrieve the WSDL file and extract the end point address from the WSDL file itself.
In this case, decorating the UDDI accessPoint with a useType="wsdlDeployment" is appropriate. A sample of such behavior is as follows:
<bindingTemplate bindingKey="uddi:example.org:catalog">
   <description xml:lang="en">
       Browse catalog Web service
   </description>
   <accessPoint useType="wsdlDeployment">
       http://www.example.org/CatalogWebService/catalog.wsdl
   </accessPoint>
   <categoryBag>
       <keyedReference keyName="uddi-org:types:wsdl"
       keyValue="wsdlDeployment"
       tModelKey="uddi:uddi.org:categorization:types"/>
   </categoryBag>
</bindingTemplate>In the example above, a client would be able to parse the result of the bindingTemplate and determine the end point of the Web service within the WSDL file discovered in the accessPoint element. Note that the bindingTemplate has also been categorized with the "wsdlDeployment" value from the uddi.org:categorization:types scheme so that it can be discovered through a find_binding API call.
1) This means for me that providing one binding with useType=wsdlDeployment should be enough.
2) Sadly the "Business Service Control" of the Service Registry (Publish new WSDL service) does not create the correct structure needed by the bpel-engine. The "Publish new WSDL service" wizard just creates one service with one binding with useType=other (http). So if i want to reuse this published service from bpel (as a service consumer) i have to switch to the "Service Registry Admin Control" and create a second binding with useType=wsdlDeployment. But i don't want the developers to get inside the "Service Registry Admin Control"! They should only work with the "Business Service Control".
All this makes the usage of the service-registry very unhandy and reduce the acceptance for developers because of unnecessary manual steps and broken security principles.
My wish for this issue is that the "Publish new WSDL service" inside the "Business Service Control" of the Service Registry would additionlly create this needed binding with useType=wsdlDeployment.

Why does EJB needs two interface???

Hi All,
This has been asked by many ppl and many of you might be having
the correct answer for it. Please tell me....
Why does EJB needs two interface (Home and Remote Interface)?. Why not one?
Thanx to all...
Regards
GoodieGuy

Hi Goodie ,
Its good question and its a very valid one , one has to have doubt
why two , why not one ..
Here the answer goes ..
First of all you need to understand that its a distributed computing technique ie I mean lot of people will be accessing the bean at the same time , right ? OK , you cann't access the bean directly.
and lastly the stateless and entity beans do instance pooling.
The very purpose of having two interfaces is
1) To differnentiate the bussiness logic and life cycle methods .
2) The home interface inititates life cycle methods like creation , destruction etc .
3) There are lot of beans in the container , and through home you are
creating the instance or accessing one of them .
4) Once you have home object using it we get the remote object ie the instance of the bean that you want to access if stateless any bean can be called , if statefull depending upon the parameter in create method that respective bean is created and invoked .
In ejb 1.0 and 1.1 even though the bean and the client are in same jvm its assumed that they are remote and in 2.0 Ver we have local this is to avoid network traffic .
Hope you have got the answer , but if u still need clarification
read EBRoman book first and second chapters thoroughly and then proceed
a head.
Bye

Why do I need Quick time 7 and Quicktime 10 ?

I have just migrated from iMac5 (2.16 GHz) Mac OS 10.4.11 Quicktime 7.6.4 to a new imac 3.06 Mac OS 10.6.2 Quicktime 10.0.
Some of my quicktime files play ok but others prompt me to download quicktime version 7. Why do I need to do this ? (There seem to be a lot of problems with this looking at the forums). All the files play on the old mac. Why isn't Quicktime forward compatible or why is there no import facility so that you can make your old files compatible ?
Or am I missing something ?

Some of my quicktime files play ok but others prompt me to download quicktime version 7. Why do I need to do this ?
Because your system thinks you are missing specific codecs required for the playback of certain compression formats. In some cases this may be an installation problem in which the codec was "lost" or "orphaned" during the update process. In others it may be a need to update the component to work properly under the dual QT X/7 framework installed under the Snow Leopard OS. You need to check the Inspector/Finder Info or similar window to determine what specific codec is causing the problem and then re-install or update that specific codec/component/package.
(There seem to be a lot of problems with this looking at the forums).
Most of the problems are "self-inflicted" by individuals who, rather than studying the problem symptoms, analyzing them to determine their cause, and then fixing the problems, elect to immediately delete and re-install software -- often attempting to mix components from different operating systems and/or update versions of the software in their haste.
All the files play on the old mac. Why isn't Quicktime forward compatible or why is there no import facility so that you can make your old files compatible?
I am running both Leopard and Snow Leopard variations of QT v7.6.6 and all of my "old" files have remained compatible -- to include MPEG-2 video and a limited number of third-party supported compression formats. Since my configurations continue to work properly, my first guess is that you have an unresolved configuration problem or inability for your QT X 64-bit routines to communicate/switch properly with the 32-bit routines as required for your content.
Why do I need Quick time 7 and Quicktime 10?
Technically, you probably don't. However, as an old QT 7 Pro user who likes many of the QT 7 Player controls/options/features better than QT X's new but more basic features, I maintain both in active service and tend to use QT 7 as the default player of most of my work flows. Still, this is up to the individual. I am in no hurry to rush the changeover from an older but still more reliable QT technology to a more modern, but as yet, less mature and well tested "new" QT technology. In short, I feel it best to make the most of both dispensations during the development of this "new" version of QT.

If you computer is working fine you do not need to reset this. It is not a maintenance procedure.

If the new SIM is working, and I backed up the Iphone-4, why do I need to to RESET and Restore, as mentioned in the "About Unlocking" instruction?

I think you haven't told us the whole story. If the phone was working on multiple carriers before it was officially unlocked it was hacked to do so. If it wasn't, and you haven't seen the message "Congratulations. Your iPhone is unlocked" then you must still Restore iOS on it to get this message.

Why we need two Joins (Left and Right)

Hi,
Why we need two joins while we can do it just by replacing the tables?
Query 1.
SELECT e.ename, d.dname
FROM emp e LEFT JOIN dept d ON e.deptno = d.deptno ;
Query 2.
SELECT e.ename, d.dname
FROM emp e RIGHT JOIN dept d ON e.deptno = d.deptno ;
The same result of Query 2 can be get from following query with LEFT JOIN.
Query 3.
SELECT e.ename, d.dname
FROM dept d LEFT JOIN emp e ON e.deptno = d.deptno ;
So why we need LEFT and RIGHT Joins while we can do this by just replacing tables position ( as in Query2 and Query3).
Regards,
Danish

Any other suggestions?What do you find lacking in the answers that have been suggested so far?
Why would you restrict the syntax so that you only had one of the two syntax options? That forces developers to write queries in a particular way. If you only had a LEFT OUTER JOIN operator, for example, the first table would always have to be the one that drove the number of rows in the result set. Sometimes (most of the time in my experience), that's a sensible way to approach the problem. But occasionally you get problems where you want to start with the sparse tables and join to the denser tables and having the RIGHT OUTER JOIN makes it much easier to approach the problem that way.
Re-ordering the tables in a query using ANSI syntax is also not necessarily a trivial endeavor. If you're working on building up a query (i.e. join 3 tables, verify the results, join a fourth table, verify the results, etc.) it's potentially non-trivial to change the order of the tables-- you may find that you've inadvertently changed the semantics of your query and now you have to backtrack a bit to verify the new logic.
It's also the same reason that you have multiple ways to write a loop or multiple ways to iterate through a collection. While it's completely possible to rewrite any loop in the form
LOOP
<<do something>>
EXIT WHEN <<something>>
<<do something else>>
END LOOP;that's not always the clearest way to express a piece of logic. Generally, a nice FOR loop or a nice WHILE loop is simply a clearer and cleaner solution. Similarly, sometimes a LEFT OUTER JOIN is a clearer way of expressing a SQL statement and sometimes a RIGHT OUTER JOIN is a clearer way of expressing it.

Services Registry in PI 7.1 - What is this and where is it used?

Hi,
Can anyone tell me what is Services Registry in PI 7.1 ? What featuers are available in it and where is it used or how its helpful?
I dont have access to it in my system, so am curious to know the contents of it!!
Do we define global data types by any chance in the Services Registry ?
Cheers,
S

Hi,
What is Service Registry?
Definition: Service Registry is a registry for Webservices that is located centrally within an SOA landscape. In simple words u201Cwhere are our services implemented?u201D can be identified by using Service Registry.
PI 7.1 contains a UDDI v.3 compliant Service Registry contains information about services provided in that landscape with references to the WSDL metadata relevant for those services and to the locations of the callable service endpoints.
How the Service Registry used in PI?
1.     As a Webservice provider we can publish Webservice.
2.     As a Webservice consumer we can search for and find Webservices for consumption.
3.     We can test our Webservices.
4.     Manage third party Webservices and classify them to provide them for consumption in our system landscape.
5.     Providing Deployment information (i.e End point information).
Enterprise Services Repository (ESR):
To support strategic service oriented approach SAP provides a new Enterprise Service Repository. ESR is a central repository of information that contains all the services. ESR is a container, stores all the underlying Meta data of application objects like service interfaces and descriptions. The global data types, interfaces and business processes maintained in Enterprise service repository which can be reuse where needed. The first implementation of ESR and its associated editors come in SAP Netweaver04u2019s, which has been evolved from NetWeaver Exchange Infrastructure Integration Repository. Enterprise service repository is a design time repository of service objects for ESA. You can model all service design objects for a process and can reuse the data types and service objects which are already maintained. All enterprise services are published in a central Enterprise service repository so they can be used by anybody who really needs that service includes customers and partners.
The Enterprise Service Repository is the evolution of what it was known as the Integration Repository in XI. Now the Integration Repository is called the ESR and XI is called PI. Using the Integration Repository as foundation for the ESR made a lot of sense since many of the capabilities were already there: metadata storage, defining message types, data types, operations, etc.
     ESR is just like Integration Repository for XI. Here you can design/define your Service Interfaces and Enterprise Services.
     ESR is the central repository in which Service Interfaces and Enterprise Services are modeled centrally and their metadata is stored.
     In simple words u201CWhat does the service do and what does it need?u201D can be answered from ESR.
     ESR is used for: -
1.     Definition of Processes and Services
2.     Store Service Metadata
3.     Central Modeling and Design Environment.
Global Data Types
     Definition: Global Data Types are company-wide, defined data types based on international standards. They are based on the SAP methodology and are defined in a standards-based way in the ESR.
     They are based on the ISO 15000-5 and UN/CEFACT CCTS standards and act as the semantic building blocks for service interfaces.
     Global Data Types help you in standardizing service definitions across your organization and provide the key building blocks that can be reused across all your service definitions.
     Global Data Types have been approved SAP-wide by the Governance Process for Business Content.
     Global Data Types have been defined in the ESR and are described by XML schema.

If I am the sole user of my laptop why do I need an administrator login and pw to download OSXMaverick or Adobe Flash Player?

I was not going to download Maverick because I had heard many less than favorable reviews. However, I started running into issues yesterday and now am stuck. I went to upload some images to a FB album and received a message telling me that I would need to download Adobe Flash Player or otherwise i could only upload one image at a time. Then I went to view a friend's video and received the same message. I chatted with a few fellow mac users who suggested I download OSXMaverick. I started to and received a message telling me I needed an administrator login and pw. I used my Mac Id...no go. I am the sole user of this device and always have been. I have no recollection of running into any such issue when downloading OSXMountain Lion. Why gives?

You are not the filesystem owner outside of your login directory. By assigning administrator privileges, you are now authorized to install software (with a challenge for your login password, not your Apple ID) where you otherwise would not be permitted.

Why do we need to override Hascode and Equals method?

Hi,
== checks if the two references are equal and .equlas will check if the value is same, if we want .equals to take care of both reference and value are correct. why cant I just override equals with an extra check that references are equal(==).
Please someone elaborate on this and also tell me what role hashcode plays in this.
thanks
Anirudh

Please someone elaborate on this and also tell me what role hashcode plays in this.The reason that it is good practise to override equals() and hashCode() together is to maintain consistency.
Hashcodes are used by all Java collections that contain the word 'Hash' in their name, and may also be used by other programs that need a hash code for identification; so if you supply one, you must follow the rules (which you can find in the API for Object.equals() and Object.hashCode()).
The main rule is this: *objects that are equal() must have equal hashcodes*.
Note that the reverse is NOT true: objects that are not equal() do not have to have different hashcodes, but it is usually better if they do.
There is quite a lot to know about hashcodes, and what makes a good one, so I suggest you follow dcminter's advice if you want to be a happy and prosperous Java programmer.

Why do I need to connect QTR and S+ directly on the strain gage?

I connected two wires with a 2" 120-ohm strain gage. Later, connect these wires to a strip connector. Now connect the red wire from NI system (SCXI-1314 which is already converted for 120-ohm) to red in the strip. This red is P+ in SCXI-1314. Now I connect the black (QTR in SCXI-1314) and white (S+ in SCXI-1314) to the white wire on the strip connector. Unfortunately this did not work. I got a constant strain output. But when I connect the black (QTR in SCXI-1314) and white (S+ in SCXI-1314) to the strain gage directly it works fine.
I tried with 4 strain gages and got the same result.
It will be great if any one can tell me what went wrong?

Hi Shaurav,
Sorry, in my last post, I meant to say "SCXI-1520", which I am assuming you have because you have the 1314 terminal block. The SCXI-1520 has programmable gain, as mentioned HERE. Also, I recommend looking at THIS discussion forum post becauseit talks about the different ways to set that gain. Have you tried applying a gain in Measurement and Automation Explorer? How are you programming this? Thanks!

Why reports are needed to compile again and again

Whenever we make a database change all reports needs to be recompiled. It means when we give our user a new application we have to give him *.RDF files so that when he run the script to run reports he would need to recompile all reports.
My question is
how can it be preventd?

Hi,
It can not be prevented, you should recompile reports when changes in database stored PL/SQL.

Why do I need to restart Apache and Tomcat every time a java file is change

If a java file is changed and complied the changes are not reflected if Tomcat is not restarted.
The settings in server.xml are as:

<Context path="/manager" docBase="manager" debug="0" privileged="true"/>
<Context path="/cf" docBase="cf" debug="0" reloadable="false"/>
Here "cf" is my Application folder under webapps. The reloadable property when set to "true" for standalone Tomcat on Windows98 reflects the changes for compiled java files without restarting Tomcat. But on Linux 7.1 with Apache 1.3.19 and Tomcat 4.0.3 this is not working.
Also tried out with Manager Application of tomcat-users.xml with reloadable="false" as well as reloadable="true",
But when I reload the application using the command
http://servername:8080/manager/reload?path=/appli.name
It tells me that the application is reloaded but changes in the java file are still not reflected.
Also when reloaded through Manager Servlet, Only my load-on-startup servlet is reloaded, but other java classes are not.
Is it neccessary to execute this reload command from the server itself. I m executing it from a remote m/c. and have mapped the application with a domain name virtually.
Is it the case with Tomcat on Linux with Apache. Or is something going wrong on my part.
Can someone Help out plz.

Rupali

or you can "touch" your web.xml file.
touch web.xmlor that command is for *nix systems, not sure what the Windows command is. But basically, when you edit the web.xml, even if it means updating the last modified time, it will restart only your application and you should see the changes.

Why does the system need two average costs - 'Average' and 'Average Rates'?

Hello Gurus!
The documentation does give definitions for 'Average' and 'Average Rates' cost types, but at a very basic level.
http://docs.oracle.com/cd/A60725_05/html/comnls/us/cst/settask.htm
I would like to know why the system needs two costs? How are they calculated and how are they used?
Thanks!

Hello,
I can suggest you a workaround that will help you keep only the 64-bit version of Photoshop.
Visit "Uninstall a Program" in Windows 7 Control Panel and uninstall Photoshop completely.
Visit this page and download trial version of Photoshop.
Run the installer manually and choose the 64-bit version only (uncheck 32-bit version).
Launch the product and specify your Adobe ID credentials.
The product will switch to non-trial (i.e. full) mode when it recognizes your Adobe ID.
