Report on web service
APEX 4.0.2
Created a RESTful web service with input and output parameters. Created a report region on the web service. It generates a SQL report with the following query
select extractValue(value(t),'/*/op1') "op1"
, extractValue(value(t),'/*/op2') "op2"
from wwv_flow_collections c,
table(xmlsequence(extract(c.xmltype001,'/path/to/output'))) t
where c.collection_name = 'OUTPUT'1. How/when is the web service invoked to populate the collection?
2. How are the input parameter(s) passed to the web service?
Thanks
Hello Vikas,
>> I thought that's exactly what the wizard was supposed to do
You are correct. The question is whether you used the correct wizard.
As I understand it, before you are able to generate a report on your Web Services you need to define them. First you need to create a RESTful Web Service Reference - http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21674/advnc_web_services.htm#CHDDIHEA . Then you should go to the Forms wizard (and not the Report wizard, as I suspect you did) and choose the option of Create Form and Report on Web Service - http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21674/advnc_web_services.htm#BABDDBIB . This wizard allows you to take care of the necessary input items, and also to name the collection to be used for the results ( Temporary Result Set Name ).
I’m no expert on Web Services. I only tried it once, long time ago, so from here on you're on your own :) .

Arie.

SQL 2012 R2 - SSRS with the Report Server Web Service URL, can't access
Hello:
I am installing Dynamics CRM 2013. When I am on RS Configuration manager; I am running into the SSRS (SQL 2012 on Server 2012)SQL issue, can't access the
http://servername/:80/ReportsServer or
http://servername/:Reports web pages
The database server has SSRS native mode installed, it is using a domain account for the service credentials. This account also has permission to log on a service in the GPO
Account is a domain admin and is a local administrator
SQL server is 2012 R2 on Windows Server 2012. User base is less than 60 people and they have SharePoint 13 on the same SQL server. Server more than enough resources.
Any assistance would be appreciated.
Thanks..DanHi DCas1,
According to your description, you could not access
http://servername/:80/ReportsServer or http://servername/:Reports web pages from Reporting Services configuration manager, SSRS in configured in native mode and the account you used is a local administrator.
In Reporting Services, URLs are used to access the Report Server Web service and Report Manager. Before we can use either application, we need to configure at least one URL each for the Web service and Report Manager. If we are using the Reporting Services
Configuration tool to create or modify the URLs, we can accept the default values for a URL or specify custom values. When we create a report server URL, we must specify the following parts: Host name, port and Virtual directory. In order to improve the efficiency
of troubleshooting, I need to ask several questions:
Since the default URL is http://<computername>/reportserver, did you type the URLs manually? or the URLs configured in Reporting Services configuration manager are
http://servername/:80/ReportServer and
http://servername/:Reports?
Could you provide detailed information of error log(default location: %programfiles%\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\LogFiles)?
For more information about Configuring a URL, please refer to the following documents:
http://msdn.microsoft.com/en-us/library/ms159261(v=sql.110).aspx

Hello Experts,
I am working on SAP BO 4.1. I have made several dashboards on top of web services ie;Web Service Method. I have 2 systems in BO ie; Development and Production Systems.The BW production system is connected to BO Development and Production both.
The Webi reports are made on top of BI BEx Query. From the webi reports, BI Web Services are made on top of which the dashboards are made further.
The Webi Reports, Web Services and the Dashboards everything is made directly in BO Production.
My question is, Can I transport the Webi Reports and the Web Services from BO Production to BO Development?
And If yes, will it have any other impact on webi reports, web services or dashboards?
Thanks & Regards,
Alfred ThomasHi Gill,
As per your reply,with the promotion managament i have make the web services again manually in Dev system...Right?
Is there any way possible that i can transport the webservices and the webi reports usind Query AS A Web Service Designer. And if yes, through this QAAWS will the WSDL or the URL required for the web services in the connection button in dashboards will automatically updated or changed as per the Development System?
But i am not able to enable the "Deploy to Other servers Option" in QAAWS.
Can you please help?

Correction for Daily Report Log Web Service
In the August 29th iTunes U Administrator email, there was a mistake in the example for the Daily Report Log Web Service.
The example showed:
http://deimos.apple.com/WebObjects/Core.woa/API/GetDailyReportLogs/example.edu?S tartDate=2007-07-01&EndDate=2007-07-17&destination=example.edu&username=ADMIN&ac cesskeys=Administrator@urn:mace:itunesu.com:sites:example.edu&emailaddress=foo@b ar.com&displayname=test&expiration=1186086577&signature=4443ac48a8ae1a0c50dbfb35 f201b6d0db14b16d
There are extraneous form value pairs in the above example. The POST form values required to get a daily report are:
StartDate (EndDate is optional) - format YYYY-MM-DD
credentials
identity
signature
An example of a correct request:
http://deimos.apple.com/WebObjects/Core.woa/API/GetDailyReportLogs/example.edu?S tartDate=2007-09-12&EndDate=2007-09-13&credentials=Administrator@urn:mace:itunes u.com:sites:example.edu&identity=%22JaneDoe%22+%3Cjdoe%40example.edu%3E+%28jdoe%29%5B42%5D&signature=38bda70d9aa6975ae8756754034feb6e3c794aca4b21665f6dc85d2ed42d4 f6bCurrently displaying audit log reports in REST or API is not supported by Microsoft.

Apex 4.1 Form and Report on Web Service Report displays nothing
Hello I created and tested a webservice using the test feature in Apex 4.1.
I know the results is a string of 1 row.
I created a Form and Report on Web Service. When I run the form there is nothing displayed in the Reports section its just blank.
If I run the sql from the results region I get no data found.
Is the problem the returned data is not stored in the collection?
Edited by: Oracle Primavera on Oct 26, 2011 3:32 PMWhat would be the reason for the following.
Testing the webservice in apex returns values.
However when I run Form and Report on Web Service Report if I query the collection it is always empty?
Does anyone have any experience on this issue? Is it a bug? Please some hints I have been trying for two weeks without success. -
Export with crystal reports as web service
In order to create 3 tier architecture for security enhancments, I am using crystal feature to publish report as web service. As far displaying these reports on viewer is concerned, I have got that part working by setting the datasource to asmx and then using the viewer to set the parameters and logon information.
However currently I also have export button on the UI which basically used the ReportDocument and wrote the excel to Http stream. And this is the part where I am now struggling with crystal as web service as it does not expose ReportDocument. I have scanned all forums and have been googling for a while but reaching nowhere.
Please help if someone has already dealt with similar problem.
Thank you.I don't think you will be able to do this from the button. Reason is that the web service only works with the viewer and there is are no exposed export API associated with the viewer. The only export APIs are based off of the report document object.

ORA-02263 when creating Report on Web Service Result
Hi,
I'm using Application Express 4.2.1.00.08 and I'm having problems creating a report on web service result.
This is the tutorial I'm using: http://docs.oracle.com/cd/E14373_01/appdev.32/e13363/web_serv.htm (yes, I realize it's intended primarily for APEX 3.2).
I am able to create the web service, but when creating a report on web service result, I get the following error in the last step:
ORA-20001: Unable to create form on table. ORA-02263: need to specify the datatype for this column.
I have tried creating a report on the same web service result on apex.oracle.com (Application Express 4.2.1.00.08) and I don't get the error, and I am able to create the report.
The same thing happens with another web service, so I'm puzzled.
What could be the problem?
Thank you.I wasn't able to solve the original problem, but I was able to recreate the process manually, using APEX_WEB_SERVICE.PARSE_RESPONSE function, documented here:http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_web_service.htm#autoId10

How to publish Report Viewer reports as Web Services
I have some reports templates (.rdlc) having only business objects as data sources (no direct SQL connection). They are working well with Windows Report Viewer. Now I am think to make the reports available via web services to multiple apps. Is there
a way to do that? Any sample?
Thanks,
JasonHello,
SQL Server Reporting Services provides access to the full functionality of the report server through the Report Server Web service. In order to meet your requirement, you
can try to converting an .rdlc file to an .rdl file
and then deploy the report to report server.
If you want to rendering the report in your application, you can try to use the ReportViewer controls in remote processing mode.

Is there a way to get system usage reports through web services api?
Where I find some examples?No, they don't 'need' web services. Xcelsius uses Excel for it's data and you can use web services to load the Excel model with data, but it is not required. CR has a variety of data connection options.
Web services is a popular method of retrieving the most up-to-date data, but is not a requirement.
Hope that helps,

Hello,
We are using Sharepoint 2010 and SQL Server reporting services 2008 R2. We have the sharepoint site bound to port 443 using a certificate. We also have the same certificate bound in the reporting services configuration manager's
web service URL tab. In CA should we put the SSL URL or the non SSL URL? Right now in CA it has the then non SSL URL,
http://fakehostname/ReportServer_REPORTSERVICE. We have some sporadic issues and I am wondering if setting this to our SSL URL will help. Please let me know
if you have any questions.
Thanks,

How to deploy a report with web service datasource
Hi Guys,
I have a RPT file(report) which is using some web service call to get data source and Information.
I am not able to deploy it properly as It gives " Error in file testReport Unknown Database Connector Error " while click at preview at server Central management Console.
Please tell me some way to resolve the issue.
I am not sure If I need to configure something at C:\Business Objects\common\3.5\java\CRConfig.xml for web service.
Actually, We are using web service call from report it self and probably there are some steps missed by me for deployment.
Sincerely,
Sanjay Patel
Edited by: Adlyd Joseph on Mar 19, 2009 6:57 AMHi Sanjay
First you create a report using the data source in Crystal Reports DesignerStand Alone Application and then save it to repository.
This is the easiest way to do it.
You can refer to Crystal Reports User guide and also BOXI Admin guide for the version you are using.
You can download the above from help.sap.com
Hope this helps!!

How to provide the data directly for the report using web service
Hi all,
I'm trying to execute a report from the webservice API (using BIP version 10.1.3.4) and want to provide the report with a pre-fetched data set. According to the Dev-Guide, I should use element /ReportRequest/reportData for this, but I can't find a proper example illustrating this use case. The problem is that I don't know how to enter my data set into the element. My data set is xml (text) while the data type of the reportData element is base64binary.
I've tried something like the following, but without any success:
...<reportData>
<ns1:rowset>
<ns1:row>
<ns1:emp>
<ns1:name>
</ns1:emp>
</ns1:row>
</ns1:rowset>
</reportData>
...Any help is highly appreciated.
Thanks in advance,

Edited by: Harm Verschuren on Nov 10, 2008 1:01 PMHello,
Thanks for your answer, the situation is a little different from what you describe.
We make a call to BI Publisher via a Web Service (PublicReportService) via the ReportRequest operation.
The report we call contains a query to a database.
When we do not include XML in the reportData field then the report data is obtained from the Database and the report result is returned via the Web Service.
!http://s3.amazonaws.com/twitpic/photos/full/2863197.jpg?AWSAccessKeyId=0ZRYP5X5F6FSMBCCSE82&Expires=1235722431&Signature=oboPzLWqQDwB2AGCDCAj3ujHRi4%3D!
When, however, we include XML data in the reportData field, then we see that ONLY the XML data in the reportData field is used, and NOT data from the Database.
!http://twitpic.com/img/1pzrp-81573d3dde07b9b643d91800cf2715ef.49a79f9e-original.jpg!
Is there a possibility to combine the two?

Is there any way to download a report by web services or know its content?
Hi everyone,
I need to know, maybe, using web services or anyway I can if a report will show some result when someone executes it, or if it just will show no results.
I hope that there is any way to know the number of lines that will be returned from the report, or maybe download the report to a csv son I can open the file and know its content.
Thank you.
Kim.Thanks for the answer
And do you know another way to know if a report will show any result or not without before to open it? maybe with a call by the url...
Thanks, Kim -
Integration with a Reporting Engine Web Service
I want to use a separate reporting engine for my reports. That is, use APEX to perform the filtering and parameter settings and preview the result in APEX. But the final formatted output will use a more complex layout. Sorry, cannot use BI Publisher or PL/PDF (license issues). Other FOP solution isn't sufficient as well because I'm planning to centralized our reports.
I already tried using Jasper Reports (also BIRT and Pentaho,they seem identical to me) Web Service but with no luck. I don't want to invest too much time in learning these tools since I don't know if it will ever work with APEX.
We do have SQL Server 2005 but I'm currently learning its reporting services. I'm a MS Access developer and already have enough of it. Anybody got a suggestion?
ThanksHi Mertz,
Well you have to bear in mind that Oracle have made it incredibly simple to integrate APEX with BIP to produce some visually stunning reports that contain data that can be pretty complex.
However...obviously you need to stump up the money for BIP to get that level of ease/functionality.
So, what you're really asking is: is there a way I can produce output just as complex as BIP without the price tag of BIP?
If that's the question the answer is definitely yes, you can use FOP. Anything you can do using BIP (and the BIP Desktop) tool you can do with FOP (or pretty much everything, I haven't found any real big exceptions to the rule).
However, the 'price' you pay with FOP is that it's another layer that you need to learn about (unlike diving into the BIP desktop plugins to design your form). However you do get complete control over the layout of your exports.
John.
