Apex app - Web service

Can we create a web service using APex application.
I have tried calling other web services from apex, but was just curious to know if we can create a web service that other applications can call from their apps?

knut,
The 11g Native Web Services is a nice option.
If your application's logic is contained in stored procedures or packages,
then you can expose it as web services without writing any extra code.
It's good re-use. Call the procedures directly in Apex, or as web services from other environments.

Fusion Apps web service call fails with error access denied (oracle.wsm.security.WSFunctionPermission)

Hello Guru,
I am trying to call a supplier service from SOA/OSB.
But while calling the service it is failing with the below error message
access denied (oracle.wsm.security.WSFunctionPermission http://xmlns.oracle.com/apps/prc/poz/suppliers/supplierService/SupplierService#getSupplierVO invoke)
As per OER cookbook i have attached the "oracle/wss_username_token_client_policy" to the Fusion apps web service.
I am trying to pass security credentials to the service by using all the methods... through composite ..through bpel through wsse header but in all cases i am getting similar error.
Please let me know if some one has called the fusion apps web service to create a supplier of solution to my problem as mentioned above.

Hi Sai,
Thanks for the quick and correct response. Yes, after doing the research, I'm also came to same conclusion. But what stops me here is that where exactly I need to check for this permission.
I mean the theory what I built on this Authorization/Permission is that:
For the resource - WebService (SupplierService), there is an assigned application role for which the Entitlement/Permission is provided.
Pls. help me in the below items:
a. What is the application role(in role hierarchy) assigned to this resource(Webservice). Which page I need to check(navigation) this and the required credentials..
b. What is the Entitlement provided for this application role for this operation (getSupplierVO) invoke.. Which page I need to check(navigation) this and the required credentials..
Thanks in Advance.
Thanks & Regards

Apex and web services

Hello everyone,
I've started looking into SOAP and web services, and have used Tyler Muth's tutorial to email and FTP BI publisher reports using APEX.
I was wondering if it is possible to create an on-screen report (i.e. an interactive report) using a web service?
I've managed to return values to form fields using web services...I was always under the impression, from before I looked at web services, that creating an on-screen report using data from a web service was one of the main things you could do....
Please could someone let me know if this is possible, and roughly how you'd go about doing it?
Thank you in advance.
Robin

Hi Robin,
I think I have implemented the same thing which you are trying to do
The followinf is the response of a web service from BI Publisher. You can check the response using the statement
select clob001 from wwv_flow_collections where where collection_name = <name_of_the_collection_u_specified_while_sending_the web_service_request>

APEX soap web service

How do i get a response from a soap webservice and insert it into a DB

MTOM Encoded Web Service Response

Hi,
I am trying to call from APEX some web services that are MTOM encoded and the calls are failing.
Does APEX support MTOM encoding? I am using the apex_web_service.make_request function.
Below is a comparison of 2 service raw responses from soapUI, one that works with APEX and one that doesn’t.
Service 1 Raw Response:
HTTP/1.1 500 Internal Server Error

--uuid:2505d950-8e95-4cd7-a350-a73962f5b748—
Service 1 works with APEX, it has a standard “application/soap+xml” content type and XML follows immediately after the header, which APEX expects and is able to parse.
Service 2 does not work with APEX, it has the specific MTOM “multipart/related;type="application/xop+xml"” content type and after the header the uuid reference for the multipart response.
Any idea on how to handle these types of web service calls from APEX?
Thanks!

Hi
Have you found the workaround?
Sorry for refreshing topic. Flag mustUnderstand ='1' in response is unussual thing.

APEX post restful service inserts null value

Oracle APEX 4.2.5
Oracle Rest Data Service 2.0.7
Apache Tomcat 7
Oracle database 11.2.0.4
Oracle APEX PUT web service inserts null value into column. This is either a bug or the documentation does not properly cover how to correctly set PUT restful services.
GET web services works fine.
I have granted the role of apex_rest_public_user to both apex_public_user and the schema owner.
The payload is a small xml document, but even a text document will yield the same result.
I am using the Oracle REST Data Service 2.0.5
Web service code:
RESTful Service Module: software_details/
URI Template: xml_parser
Method: POST
Source Type: PL/SQL
MIME: Types Allowed: application/xml
Requires Secure Access: NO
Source :

insert into clob_test (x)
values (blob_to_clob(:body)); ## according to some online post, :body is where APEX places any data being transferred through a web service. I have yet to find any official ##documentation on it.
commit:
end;
##Blob_to_clob function code
CREATE OR REPLACE FUNCTION blob_to_clob (blob_in IN BLOB)

Thank you,

I am experiencing the same issue.
I implemented the 'chunked file loading' example from Kris Rice's blog at Kris' blog: August 2013 in y workspace at the Oracle hosted APEX site and everything works fine.
However, I get a null value for 'data' when I implement the same example at my work site.
Work Site config is
Apache Tomcat 7
Oracle REST Data Services version : 2.0.6.27.18.06
Application Express 4.2.2.00.11
Oracle RDBMS 11.2.0.3
I am NOT using SSL at my work site. However this does not seem to affect a POST with form values.

Is it any policy error or the authorization error ...
Are there any navigation steps I can check the existed permission on this resource etc..,

Restful Web Services - First Party Authentication with custom authentication schemes

Hi
I've successfully enabled security using first party authentication on our Restful web services however these only work with the built in Apex accounts and not other authentication schemes.
Ideally I'd like to authenticate against LDAP, however when I enable this authentication scheme the restful services don't work as they only support the Apex accounts.
Has anyone implemented LDAP authentication for Apex restful web services, either directly or using Glassfish ? Does anyone know if support for custom authentication schemes on the feature roadmap for a future Listener release ?
I attempted to configure the glassfish application against LDAP but am still working on it.. glassfish never challenged the client to authenticate (it's only to be for the web service endpoints and nothing else), so any pointers on how to set that up for Apex would be appreciated.
Thanks
Kes

Hi Gemma,
unfortunately at the moment you are caught between a rock and a hard place:
- As you point out there is no way in APEX for a user to self-register themselves, short of developing your own table to store users and configuring APEX custom auth to authenticate against that table
- Listener can only authenticate against the the APEX user repository, it cannot integrate with custom APEX authentication.
There may be other options though, by leveraging the authentication capabilities in the JRE and/or WebLogic/GlassFish application servers. We're interested in addressing this use case, so if you wish to investigate further please send me an email ( colm <dot> divilly <at> oracle <dot> com).
Thanks,

Cannot connect to web services HP 7525 printer

It used to work fine. Now I jsut get the message "unable to connect to web services......" I've chcked and the printer is connected to wifi. I tried the solution posted " put IP address in a browser etc...... but when I do that in Exploer all I get is jiberish, no web page with the network buttons.

Hello @JACKUSHNER,
Welcome to the HP Forums!
I understand you're receiving a message stating "unable to connect to web services" using the Photosmart 7520. I will do my best to assist you! I would start off by following this entire HP document on A Network Connected Printer Cannot Access Print Apps, Web Services, or ePrint.

MFA Server - User portal and mobile app web server should be installed where?

Hi. We are in the process of testing the Multi-Factor Auth server and are currently using it for two-factor authentication to RDS for a couple of users. At the moment we are only using the phone call/text options but I'd like to get the mobile app portion
working to test. Also still need to implement the user self-service portal for testing.
Currently I have a vm that was dedicated to MFA where the Multi-Factor Authentication Server software was installed. Now though I'm a bit confused as to if its safe to install the user portal and mobile app web service portion on this same machine
or if they should go on a different server(s)? Currently the box is internal but I'm guessing if it has also act as the web server we would stick it behind the TMG for external inbound access. Is external access to the primary MFA server ok?
What's the best practice for separation of the MFA roles; or is there none and its fine to just put it altogether?
Thanks.

Hello Col. Forbin,
Thanks for posting here!
You have a dedicated MFA server and if you install User Portal on the same server as the MFA Server, it uses RPC to communicate with the MultiFactorAuth service locally.
If the User Portal is installed on a different server, it must connect via the Web Service SDK. You can use either a username/password of a service account that is a member of the PhoneFactor
Admins security group, or you can configure client certificates. If using the username/password, you can encrypt the appSettings section of the web.config file if desired.
Under Inetpub\wwwroot\MultiFactorAuth when you edit the web.config file you need to make sure these values are set.
USE_WEB_SERVICE_SDK:
true
WEB_SERVICE_SDK_AUTHENTICATION_USERNAME: domain\user
WEB_SERVICE_SDK_AUTHENTICATION_PASSWORD:
password

Consuming RESTful web service in Apex app

Hi,
I have created a RESTful Web service through an Apex application (4.0) and published as a public web service. Can someone point me to an example of how to then consume that service in another Apex app? The output is straightforward XML that I can retrieve just by pointing the browser to the URL of the service created, but when I go to create the REST Web Reference for the receiving application, I am not sure what to put for the Response Xpath or Response Namespace. The service is meant to just return report records that were created in the REStful Web service with no input required.
The service XML looks like this:
<ROWSET>
<ROW>
<PROJ_ID>132</PROJ_ID>
<PSL_NETID>xxxxxxxx</PSL_NETID>
<PROJECT_TITLE>11g- Oracle Upgrade to RAC 11g</PROJECT_TITLE>
<CUSTOMER>OIT</CUSTOMER>
<DIVISION>EIS</DIVISION>
</ROW>
<ROW>
<PROJ_ID>132</PROJ_ID>
<PSL_NETID>xxxxxx</PSL_NETID>
<PROJECT_TITLE>11g- Oracle Upgrade to RAC 11g</PROJECT_TITLE>
<CUSTOMER>OIT</CUSTOMER>
<DIVISION>CSS</DIVISION>
Any help would be appreciated.
Thanks,
Pat

Hi,
I have made progress in this. I created the RESTful report service in an Apex 4.1 application. (previous attempt was with 4.0 version of Apex)
I then created a separate application and created a RESTful web service reference that I tested and it was successful in bringing up XML. However in Apex 4.1, when I create a report following the Wizard for creating a report based on that Web service reference I get the error: ORA-31013: Invalid XPATH expression Which I don't know how to get past. The Xpath provided in the Web service reference test gave output below and brought back a result. There was no where during the Report creation to provide an Xpath. Am I missing something or is 4.1 not quite Web service ready??
This is what I get from the test of the Web service reference in the Apex App from which I want to create a report: (I see in this XML the data I was expecting from the test of the RESTful web service but it looks like the output I get from the Web service test is more like the Report xml itself.)

Web Service in Apex

Hi
I'm using APEX 2.1.0, OracleXE 10.2, Oracle SOA 10.1.3, Jdev 10.1.3.3
I've created a webservice in jdeveloper based upon a plsql package it has 3 input parameters and return a parameter
I've deployed the webservice to my SOA apps server and tested it satisfactorily
I've then created the web service reference in APEX using the shared components utility and it appears to create the reference ok (based upon the WSDL without searching UDDI), this correctly shows the operation and input and output parameters whilst it is created via the wizard
I've then tried to create a form based upon the web service in APEX, it shows the operation but it does not show the input parameters it gives the mesage "no data found"
has anyone else had this problem?
has anyone got any suggestions?
thanks
Andrew

Thanks for this, I've tried to upgrade my APEX to 3.01 using the instructions identified it ran for 9hrs before I killed it I assume that there are some things I need to do on my XE database or my machine is not powerful enough, or something else is awry (not found any other posts on the forum indicating anyone else having a problem with the upgrade so I assume its me!)
However I have now managed to access another oracle 10g instance that does have Apex 3.01 and I have now successfully built my application on the web services generated in Jdeveloper
again thanks
Andrew

Can I deploy web service on APEX server

I have APEX 3.1.2 on 11g database.
I need to pull data from other oracle 9i databases into APEX application. I have created web service on my pl/sql package to pull data from 9i databases and deployed service on my local oc4j instance (within jdeveloper). My APEX app pull data from multiple oracle 9i database. Now I need to move my web service to my dev/test environment.
Can I deploy web service on APEX server? or do I need to deploy on another web server?
I know I can easily pull the data from other oracle 9i databases using DB link. I want to explore Web services option to just to see is it possible to pull data from multiple sources into APEX app using web service running from APEX server?.
Any help on this will be appreciated.

I am in the same situation. Consuming a web service is easy with APEX. But publishing one needs a web server that is more complex than the one that comes with APEX for free.
I am exploring the possibility of building the web service in Jdeveloper as you have. Then I will make a WAR file that I will publish to an apache tomcat J2EE server that another department runs. I believe it will work since all the components required should be in the WAR file.
I am new at this. I will let you know how it works out.
The other possibility is to upgrade the appserver to the full Oracle Fusion server (maybe). This may be expensive and be too much for just a simple web service. But then the publish to application server from jdeveloper is super easy.

Publish XDB web service on apex application

Could any one please help me out to use native oracle XML DB web service on apex application.
In apex application, basically i need to have a report that displays all PO requests with links to each request # to drill down to the form page where the vendor are allowed to submit some corresponding data to th PO request.
All i need is to know how do i use the native oracle XML DB web service to show the report to the vendors with drill down links and capture the data, the vendor submits through the form.
Thanks in advance!!

Rame

I think you might be on the wrong track. Web services don't "show" anything really. They take in either XML in the case of SOAP-style web services or an HTTP request in the case of restful web services. They typically return XML, but can return JSON or other machine readable formats. Web services don't have forms and reports. More information here: http://en.wikipedia.org/wiki/Web_service . To have a human interact with a web service, you typically have a UI layer. For instance, in APEX you can build a form or a report on a web service (the same is true for most popular web technologies).
In APEX 4.0+ you can expose a report as a restful web service, but I really don't think that is what you want to do. There's no way that I can think of to use the XDB web services to expose any component of APEX.
In short, people interact with web applications, such as APEX apps. Machines, such as databases or application servers, interact with web services.
So, do you need to expose some component of your application as an API (web service) that vendors can call programmatically from some other technology such as Java or PHP? Or do you want to build a web application that people can interact with?

Issue in calling a web service from Apps instance

Hi ,
I have created a procedure to call a function which gives response by calling a web service URL.
Requirement is,
While calling this procedure , the response data has been stored in the table. This is working fine in the back end.
Now , i call the same through concurrenet program . It is also getting stored but partially.. The exact data is missing ..other default tags are displayed in the column.
PROCEUDRE:
create or replace procedure cv_test_GetCityWeather_PROC(cityName in varchar2, country in varchar2 ,errbuf OUT nocopy VARCHAR2,retcode OUT nocopy VARCHAR2) is
xmlResponse XmlType;
begin
xmlResponse := CV_Test_GetCityWeather(cityName,country);
insert into xx_cv_test values(xmlResponse);
fnd_file.put_line(fnd_file.log, 'hghghgh');
EXCEPTION
WHEN OTHERS THEN
retcode := 'insert failed';
fnd_file.put_line(fnd_file.log, 'response of the request is ' );
--dbms_output.put_line('xmlResponse ' ||xmlResponse);
end cv_test_getCityweather_proc;

Why the outputs are different for the same procedure..
Anybody , Please help me to fix this issue.
Thanks
