Demonstration of Web Services' power

Hi,
We have to give a presentation to our clients on Web Services. Most of the literature on Web Services say that applications hosted as Web Services are better than conventional distributed systems. It also say that "Changes introduced to the Service do not break a Client's ability to use the service". Now changes can be
1.Modification to existing operations/methods
2.Addition of new operations/methods
I need a pseudo-code/sample program that demonstrates the flexible and resilient nature of Web Services architecture. That is, a scenario that will fail in conventional distributed systems when changes are introduced, WILL work fine when implemented as a Web Service. Any help will be greatly appreciated and motivate us to convince our customers of Web Service's power.
Thanks & regards,
Sudharshan Govindan

Hi sudharshang,
I'm currently finishing my graduation Project and it is about Web Services. So I have some insights for you!
"Changes introduced to the Service do not break a Client's ability to > use the service". Now changes can be
1.Modification to existing operations/methods
2.Addition of new operations/methodsThat is true because you expose your service through its WSDL description. In the WSDL document, it's described how to access the service (the method name, its parametes, the endpoint, etc). So it totally hides the service's implementation.
1) Modifying the existing methods won't make any difference to its WSDL document, that's why it's transparent for the client
2) By adding new methods,
a) if the client is dinamically finding, binding and invoking the service, it'll be transparent for the client again
b) if the client is sending a direct SOAP method call message, to invoke the new method, you'll have to modify the client to invoke the new method and you'll have to publish (send to the client, in this case) the WSDL document again!
That is, a scenario that will fail in conventional distributed >systems when changes are introduced, WILL work fine when implemented >as a Web Service. Any help will be greatly appreciated and motivate us >to convince our customers of Web Service's power.A scenario that fail in conventional distributed systems is when different distributed tecnologies must communicate/interoperate/integrate! If a situation where different systems with different technologies exists and they need to interoperate, the simpler solution is to build a new abstraction layer where every sistem expose their data and methods through Web Services.
If the same systems where designed to use Web Services since the beggining, they didn't even needed a distribution technology. Web Services will work great in this case as well!
Hope it helps,
Andre

Power Query to consume Azure ML Web Service

I've been struggling with creating a Power Query to consume an Azure ML web service and believe it's probably time for help from the community.
The Azure ML web service needs the following:
OData Endpoint Address
API Key
JSON formatted body
JSON formatted response
Chris Webb's post (http://cwebbbi.wordpress.com/2014/04/19/web-services-and-post-requests-in-power-query/) gets most of the way there, but I'm missing something.
My sample Azure ML Web Service API: https://ussouthcentral.services.azureml.net/workspaces/ca45b0a19ee14a95aecde329dcb6c2b9/services/71d0c6db78214e63b63e335e07f1dd7d/score/help
Any thoughts or examples that could be provided would be appreciated.

Using an external web service and XMLBeans

I have an external document/literal web service that I want to use
(call) from inside workshop. I have listed a small example at the end
of this email.
I am wondering if there is a way to call and receive from the web
service using XMLBeans. In the tutorial examples XMLBeans are only
used by marshaling and unmarshaling the xml structure into a string
which is what is actually passed according to the WSDL. However, in
this case (and I personally think in most cases) the schema is
explicitly described in the WSDL and passed as the message. I might
add the structures for my real service are much more complex and so
the value of XMLBeans is certainly applicable to them.
Clearly I can somehow save off the schema and generate XMLBeans from
it. The next step is much less clear, how do I tell my JCX to use the
beans instead of generating private classes to represent the
structures?
To be honest I am a little surprised that for 8.1 the WSDL->JCX stuff
doesn't just leverage XMLBeans by default instead of generating basic
classes. This would give the power of XMLBeans to all web service
calls.
thanks,
dave

Performance impact of using Web Services?

As BEA and other vendors continue to add Web Services support
to their enterprise software, what is your plan for
quantifying the performance impact and the functional
correctness of using web services before going live with the
final application?
Empirix is hosting a free one hour web event discussion on
web services testing and automated web services testing
solutions on Thursday, January 17, 2-3pm Eastern time.
To sign-up for this web event or learn about other web
events being offering by Empirix this month, go to:
http://webevents.empirix.com
For your convenience, here is the complete abstract:
The advent of web services has brought the promises of
integrating multiple software applications from
heterogeneous networks and for exchanging information
from vendor-to-vendor or vendor-to-consumer in a
standardized way.
As web service technologies are deployed within and across
organizations over the next several years, it will be
critical that web services undergo performance testing.
As with any enterprise software project, the adoption of
proper test methodologies and use of testing tools will
play a key part in the overall success or failure of
projects utilizing web services. In a compressed
software project schedule, an organization must
quickly determine if its web services will operate
successfully under a variety of load conditions. Like other
web-based technologies, successful web services will need
to respond quickly and correctly when implemented.
During our presentation, we will discuss the testing
challenges created by this emerging technology, along with
the variety of testing solutions available. Automated
web service testing will be discussed and demonstrated
using FirstACT, the first web services performance testing solution available
on the market. Using a sample web
service, automatic test case creation, scalability testing,
and results analysis will be explored.

CUP 5.3: risk analysis in workflow impossible due to web service performance?

Hello experts,
We are facing a huge challenge within a AC 5.3 implementation.
Here, AC has been used successfully with CUP and RAR for quite some time now. However, the RAR analysis has not yet been integrated into the CUP workflow. We would like to integrate the RAR analyis in CUP now.
Based on the existing role concept (that uses functional master roles and derived roles per company code, with ca. 30 company codes in place) and the shared service operations in some areas such as FI, there is a large number of users with many roles and consequently, many SoD risks (of course, they are all "repeat" risk per company code).
This leads to a long RAR analysis run time, but it's still acceptable. Analysis on permission level for such "power users" runs about 1 minute, on action level about 5-6 seconds.
However, the web service between RAR und CUP is a problem and cannot cope with our violations. We have currently set the threshold to 75000. In this case, the analysis + web service runs 1-2 minutes. However, we have some users with 200-300.000 violations. In this case, if we deactivate the threshold, we will experience a web service time-out eventually, even with analysis on action level because the amount of violations the web service has to process is the same (or even higher with some false positives).
We also have compensating controls in place for these power users, which will of course reduce the web service run-time considerably. However, this is not applicable to NEW user requests because for those, the compensating controls will be assigned only AFTER the risk analysis has taken place and the risk manager receives the workflow item.
Has anyone experienced this in the past and found a viable solution or work-around? We are basically short of options and considering dropping the project.
Note: An upgrade to 10.X is not (currently) a solution because this upgrade is scheduled and budgeted only for later.
Thanks a lot and best regards
Patrick

How to enable MSDOS program to be called from Oracle PL/SQL procedure ( Web Service )?

Hello,
Dealing with the time demanding procedure where power user is interactively execute sequence
of steps of procedure:
1. pl/sql procedure for preparing data in some table
2. java program that read data from the table and creating input txt file for MSDOS program
3. MSDOS program is autonomous component that reads input txt file and make
output txtfile.
MSDOS program is closed component, can not be modified
4. java program that insert txtfile into Oracle table.
5. Steps 1 to 4 are executed in interations driven with select on some table.
Trying to prepare re-design the procedure and not sure about which technologies to use ?
The goal is that whole procedure would be implemented in pl/sql procedure and this way could be executed
so as from power user from command line as from controlled application on any type of the client.
So if that MSDOS program would be transformed as Web Service offered on some MSWin server in the intranet.
Then PL/SQL procedure would communicate ( call this web service ) and do all the job and at the end
send status of completion and report through e-mail to the issuer of the procedure?
Not sure what technologies should I use on Oracle RDBMS server on Linux to communicate with MSWin Web service which is running MSDOS program ?

> Hi TOM,
This is not asktom.oracle.com.
> Can Possible to do in Oacle Pl/Sql...?
Yes it can be done. Simply consult the applicable manuals that contains all of the details on how to do it. The manuals are:
- Oracle® Database Application Developer's Guide - Large Objects (refer to Chapter 6 section on Using PL/SQL (DBMS_LOB Package) to Work with LOBs)
- Oracle® Database PL/SQL Packages and Types Reference (refer to the chapter on DBMS_LOB)

ODSI to Invoke an A sync Web service

We have a 2-Tier application based on Oracle 11g db and PowerBuilder 10.
Does the follwoing practice can take place? :
1.call an ODSI Program (Wraped as a service) from Power Builder
2.ODSI will collect the data from the db and send it to a SOAP end point for further processing.
Also , would it be best practice to creat my SOA landscape usign this tool rather then developing
each outbound service using Jdeveloper for example on the application side.
Appriciate your insights.

I'm not sure I understand the post. The subject says "ODSI to (can?) invoke an A sync (async?) web service" (it cannot), but then goes on to ask something different.
1.call an ODSI Program (Wraped as a service) from Power Builder If PowerBuilder supports calling webservices, then yes, you can call ODSI from Powerbuilder.
Also , would it be best practice to creat my SOA landscape usign this tool
2.ODSI will collect the data from the db and send it to a SOAP end point for further processing.The strength of ODSI is that it can part or perhaps even all of the "further processing".
would it be best practice to creat my SOA landscape usign this tool ratherThat would be a good practice.

HP LaserJet Professional P1102w won't print Web Services Information Sheet

Hi there.
I've spent the last frustrating three hours trying to get the Web Services Information sheet to print on this printer. I need this sheet in order to register for ePrint.
I connect fine wirelessly on my computer to the printer. I have updated the firmware. Twice, to be sure.
I have gone to HP Web Services and clicked Enable
The message I then get is:
"A Web Services information sheet will be printed. Review the sheet for important information."
However, nothing prints.
I have tried this process with the computer connected wirelessly through my network. I have tried it with the computer connected to the printer via USB. I have printed other things on the computer this way.
I have tried rebooting the network and the printer and then reconnecting
I have tried these steps:
http://h30434.www3.hp.com/t5/ePrint-Print-Apps-Mobile-Printing-and-ePrintCenter/eprint-printer-code-...
(I changed the preferred DNS from 10.0.1.11 and the alternate DNS from 8.8.4.4. to the values suggested)
Afterwards, there was no change. My printer continued to print in every way possible. However, it will not print the Web Services Information Sheet.
I'm very keen on getting my hands on this email so that I can register for ePrint. Can anybody help me? I would be hugely grateful.

Sorry to hear you were unable to setup the wireless again on the p1102w.
I have provided some steps in resetting up the p1102w on wireless network if you decide
to do it again in the future.
Reset the printer back to factory settings.
(turn printer off then hold down the x and the wireless button while turning on the printer until the lights start blinking then release the buttons.
Disconnect the usb cable from the printer.
Disconnect the routers power cable for 10 seconds and then reconnect it again.
Uninstall the p1102w from the computer.
(open cd and select uninstall or go to uninstall a program from the control panel.)
Run the cd again or download depending what operating system you are running.
Connect the usb cable when prompted to setup the wireless again.
Enter passwords for the network when prompted.
Disconnect the usb cable when prompted.
Should be able to print out the test page now.
Then you should be able to get the web services information sheet to print but will need to print out a self test on the printer to get the new ip address for the printer.
If further issues you can contact HP technical support at 1-800-474-6836.

Can;t enable web service on HP Officejet Pro 8600 N911a

HP Officejet Pro 8600 N911a we have installed this printer as a network printer. Everything works fine except that I cannot enable the Web service to EPrint or scan to an email. It says the printer cannot access the internet.
This question was solved.
View Solution.

Hello. First power cycle the printer, and the router to see if that will clear up the error message. To do that unplug the router then power down the printer using the power button. Then plug the router back in and once it is back up an running, turn on the printer and try to reconnect to web services
Then, if still unable to connect, I would set a static DNS on the printer. To set a static DNS you must access the embedded web server (EWS). You do that by entering the IP address for the printer into the address bar of the browser of your choice.
Once it brings up your Officejet's EWS, locate the tab that is labeled “Network”. From there look in the left column on the new page that will pop up and select IPv4, wired or wireless will depend on how the printer is connected to the network. That will bring up the page to set the Static DNS. It will be the 2nd portion of that page.
Set the radial dial to manual. Then, for the Manual preferred/Primary DNS, set it to 8.8.8.8 and the Manual Alternative/Secondary to 8.8.4.4; then click apply.
NOTE: if another message with an option to click “OK” appears, read that message carefully. Most of the time it is an option to undo the change you just did and you will want to avoid clicking that message. Just navigate away from that page by clicking on another tab.
Power cycle the printer. Once printer is back up and through with calibrations from being turned off and on. Reattempt to connect to web services by touching the icon.

Web Service portlet in PDK (Urgent!!!)

I have a .NET web service I would like to consume in the portal and present as a portlet. For several reason I do not want to use OMNI (not the least of the reasons is after 3 weeks of working with oracle tech support on a corresponding I still cant get OMNI and WebClipping running)
Either way, the WS consumption system with xsl/xslt controlled presentation as seen in Web Services sample provide in the PDK suits my needs a lot better.
Now as I mentioned I have a .NET service running and well tested.
I can indeed consume it and even apply XSL, what I cant do however is to pass parameters to web service.
I define portlet with something like:

This actually seem to work and in the _literal.xml log file I can see something like that:
<getPerson xmlns="http://myserver.com/webservices/">
<inputStr xmlns="http://myserver.com/webservices/">Yukh</inputStr >
</getPerson >
(Yukh is what I passed as urlParam)
The problem however is that service that should run a query with WHERE lname LIKE <inputStr>% returns the whole datatable rather then only those records that starts with Yukh in the lname column. In short request parameter is ignored by web service (or not passed)
The only difference between my portlet and samples (most of which dont work as advertised by the way) is that oracle _literal.xml log file doesnt have xmlns in the sub elements
<WhoIs xmlns="http://tempuri.org/">
<DomainName>oracle.com</DomainName>
</WhoIs>
(I have no idea why mine does (I define no attributes for inputStr element)
If you have any idea what I might be missing or doing wrong please let me know!!! Ill greatly appreciate.

We tried using Omniportlet. It expects the resultset in ROWSET/ROW format. Our .Net Webservice doesn't return in rowset/row. We tried transforming using XSL, but even then it didn't work.
Thanks

Error in creating Web service reference using WSDL

Hi Experts,
I'm using apex 4.1, Oracle 11g
ERROR MESSAGE: The WSDL document was unretrievable because either the URL you supplied was invalid, your environment requires a valid proxy server address for HTTP requests and you have not defined one for this application, or a wallet needs to be configured for this instance of Application Express for HTTPS requests
I know this is a famous issue apex devs faced. I'm having the same problem now. I went through many forums and websites and came to a conclusion that this is something to do with
ACL.
This is wat i'm trying.
1) I have Apex and my web service running on the same server. (We don't use proxy server to connect to W'service)
2) This is the path of the WDSL document i gave - 127.0.0.1/EPRWS/DashboardService.asmx?WSDL
3) I created a default Oracle Wallet by giving no other information other than user name password.
4) i gave the default wallet's user name, password in apex app.
5) The only data that I inserted into ACL table as follows,
BEGIN
DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('power_users.xml',
'ACL that lets power users to connect to everywhere',
'FLOWS_030000', TRUE, 'connect');
DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('power_users.xml','*');
END;
begin
dbms_network_acl_admin.add_privilege (
acl => 'power_users.xml',
principal => 'FLOWS_030000',
is_grant => TRUE,
privilege => 'connect'
END;
I guess the data inserted into ACL tables as given above to give user privilege is not accurate. Could someone explain me how to properly populate the ACL tables and what exactly needs to be inserted into both ACL tables ? And Should we give anyother information when we create a wallet to fix the able issue ?
Thanks in advance
Kurubaran.

Thanks Role for your reply. As you said i used "APEX_040100". Following script did the magic and now i can call the service. :)
BEGIN
DBMS_NETWORK_ACL_ADMIN.create_acl (
acl => 'power_users.xml',

start_date => SYSTIMESTAMP,
end_date => NULL);
DBMS_NETWORK_ACL_ADMIN.assign_acl (
