Application Express :: 4.1 Restful Services Give HTTP 404 If Cookie Is Not Sent Along
Nov 12, 2012
When I call a classic report that is exported throuh restful webservice, result depends on whether I also send cookie or not. In the first case, access is enabled, in the latter case, HTTP 404 is returned.
Restful access is enabled in the instance. Having an app with ID=101, page 9901 that is public, a classic report called MYREPORT on the restful side, the following call is issued:
/apex/apex_rest.getReport?app=101&page=9901&reportid=MYREPORT_ID&parmvalues=123445&output=json
If my browser send the cookie below with the request, I get back the result. If I delete the cookie from my browser, the result for the exact same apex_rest call is HTTP 404: Not found.
Cookie: ORA_WWV_USER_64731425336707=04893186A373057F5F1E1FCCD33113FA; PUBLIC_ORA_WWV_USER_64731425336707=-1; ORA_WWV_REMEMBER_UN=MYNAME:myworkspace
Details on my configuration is as follows:
Database: Oracle XE 11g, 11.2.0.2.0
Apex version: 4.1.1.00.23_en
Platform: Linux x64
HTTP is handles by XEXDB as folows from lsnrctl status:
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=kivi.omikk.bme.hu)(PORT=8080))(Presentation=HTTP)(Session=RAW))
Service "XEXDB" has 1 instance(s).
Instance "XE", status READY, has 1 handler(s) for this service...

I'm hitting a restriction or security feature(?) of Safari in iOS. One of our Apex applications is a page that runs in an iframe on a site. Apex is installed on a server inside our own network and is accessible via dns: office.ourcorp.com (fake name, just to clarify the situation).
We have a couple of different brands, that all have their own domains: brand1.com, brand2.com etc. All of these sites open the apex page inside an iframe. That all works beautifully in all browsers, except in Safari in iOS. in iOS, the apex page isn't showing. It seams it's because of the session cookie Apex sets. Safari can't set an cookie from another domain (a cross domain cookie). Is there a possibility to turn off the session cookie?(ORA_WWV_APP_xxx)? I also tried to set the 'cookie domain' option inside the authentication scheme to one of the domain names for our brands, but it still doesn't show up.

I'm trying to setup a dev machine to run APEX with RESTful services ahead of using Oracle's Cloud Database. Using Personal Edition, APEX 4.2.1 and the 2.0 Listener is up and running in standalone more. The problem is when hitting 'Test' on a selected REST Resource Handler, it comes up with an APEX 404 not found error, such as on the example HR REST handlers and a new test one setup.
I've followed all of the APEX and Listener instructions, run apex_rest_config.sql, ensured the various users are unlocked and tried both http and https (even though I've added the no SSL flag in the Listener config per standalone instructions.

I'm trying to connect a javascript UI control within my page to an APEX Application Process. The control calls the application process via AJAX and appends a variable number of GET / POST parameters to its URL.What is the best way to obtain these parameters from within the PLSQL procedure of the process? Or is there a better way to connect my javascript AJAX control to the Database behind my APEX app?

I'm having some difficulty securing my Oracle APEX + Oracle HTTP Server environment.
There are currently around 20 Applications running on the APEX Server, and I'd like to publish 2 of them Externally for users.
I have added a certificate to Oracle Wallet Manager to secure the OHS, but I can access all the Applications on the APEX Server by just changing the Application ID suffix.
How can allow only two applications to be accessible via the internet?

We are getting the following error when trying to access a RESTful web service coming from Apex workspace 4.2.1 and Apex listener 2.1:
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-29024: Certificate validation failure
In the Debug report, besides the above I also see:
error_backtrace: ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 543 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 1164 ORA-06512: at "APEX_040200.WWV_FLOW_PROCESS", line 396
We get that error whether we use https or http in the URI pointing to the web service. When I test the Web Service in Workspace RESTful service GUI, I get the data back. When I go build an application with a report calling the RESTful Web Service I get that error. Both the Application and the Workspace RESTful services are on the same Apex environment and even the same workspace.
What is odd is that I can actually put the URL of the web service into a browser and I get the data: (using the demo hr data in sample RESTful services.)IN browser-- [URL]
yields:

what would be causing the Error above in our application?
In reviewing the above error, I think we are realizing that we have to have the Weblogic layer SSL cert (actually the CERT from our BigIP load balancer which also does our SSL termination) imported into the Oracle server wallet where Apex is installed. Am I correct?

I have installed Oracle 11g XE . After this , i have upgraded to Apex 4.2 All it's working fine, but..... by default XE installs and configure apex to use embebed pl/sql gateway.
In this scenario, the images are stored directly in the database within the oracle XML DB repository. This may be a problem because XE have a 11GB limit and my apex aplication is simple, but it may upload pictures for customers, etc, and in this schenma the pictures will consume space in the database instead consuming in the linux filesystem.Can i install HTTP server in a 11g XE and reconfigure apexr?, or can i change to apache+listener? or more easy....can i upload images outside the XML DB in my apex application easily?

I'm trying to create a web service via the WSDL wizard (Apex 4.0.2). We are behind a firewall and connect to the internet via a proxy server. The proxy server requires authentication with a username and password. How to include the username and password in defining the Proxy Server in the Application Definition page or optionally in the alternate location in the Manual Web Service wizard page?
I assume the base definition for the proxy server is [http://]host[:port][]

Restarting oracle services through services.msc is faster then manual (In command prompt).
Even If we have heavy transaction on the oracle database But we can restart the database within minutes by using services.msc But It will take more time in command prompt(sql>shu immediate). So shall we assume here that services.msc is using shut abort command while restarting the database?

From this application i receive 2 headers, to verify this person has authenticated successfully. But how can I read these 2 headers? It doesn't work with the UTL_HTTP package, because i don't do an active request on an url.

We have a requirement like, we will get bulk data (2 GB) data file with different languages(Russian, chinese, Japanese, German) etc. and we need to load these data into our databse also we have to translate the same.
We are using Oracle 11g.
We had used Oracle httpuritype - And the below mentioned procedure PROCEDURE TEST.PRC_TRANS_GERMAN will call the function - trans_jef
Input parameter for PRC_TRANS_GERMAN - > To_language and from Language. and this procedure will store the translated word in the seperate table. Input parameter for the function trans_jef - > Word to be translated , from languae, to_language. And this function will return the translated word.
The issue I am facing is when I am passing the table of around 10000 records, around 4000 rows are not getting translated. So when i try to capture the error in exception- the error is
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1819
ORA-29270: too many open HTTP requests
When I try to re execute the missed words, they were translated. But they are not getting translated in one go because of the too many http open request.
how to resolve this ORA-29270 errror.

want to create a PL/SQL procedure, update_id(id_emp in number), that gives a new id_emp (id_emp=y) to an existing employee (id_emp=x).So before updating the EMP table, we have to :
1- create a new row on EMP(with id_emp=y) that has the same informations of the employee (id_emp=x),
2- update all tables that contains the id_emp column (update <TAB> set id_emp=y where id_emp=x),
3- delete employee (id_emp=x).
The problem is in step 2 : it creates a lot of locks and makes the DB unusable.To deal with this problem, I thought for many solutions, but the problem is how to implement them correctly and efficiently.
Before executing step 2, we have to ensure (through a marker I guess) that all the tables that have the id_emp column, are managed by our session, and any other acces (through SELECT, UPDATE, DELETE, INSERT statment) from another session will be rejected since we have a marker on that table.
When step 2 ends, we release all the tables from the markers.
My simple question : how to achieve this ?
