Leon -
If I follow your question, you are asking how to retrieve images with RESTful Web Services. It looks like your code assumes that RESTful Web Services have access to an underlying directory in the Cloud. This is not correct - Database Cloud users have no access to a file system. Instead, you would store your images in the database and use the Media Resource source type to return a .jpg without any translation or marshalling by the RESTful handler.
Hope this helps.

RESTful service and BLOB with bind variable

Hi,
Has anyone successfully created a RESTful service with bind variable to retrieve a BLOB field and render it in an Apex app? I can create RESTful web service and render BLOB field for a record with no bind variable (single row). As soon as I add bind variable my RESTful service fails -- I get 404 Error. Without bind variable it renders both in TEST tool of Workspace and direct URL. As soon as I add a bind variable it fails either way. I have reported this in an SR to Oracle support, but thought I would post here too.
I would also like to retrieve the photo into an Apex application. Any hints would be appreciated.
Thanks,
Pat

Hi Fateh -
Good question. You would identify the source type as a Media Resource, and use an SQL statement with the primary key and the BLOB column. When you use Media Resource, you are essentially telling your Database Cloud Service not to marshall the data, just to send it - which is exactly what you are looking for.
With this implementation, you would have to have a separate SQL call for each BLOB retrieval. However, you might be able to use a PL/SQL block as the end point for the RESTful Service and take care of multiple BLOB processing in the block.
Hope this helps.

Restful Services and Apex

Do I need to install apex listener in order to use the Restful Services.
We are on apex 4.1 and use modplsql apex.
Do I need to also install apex listener in order to use the restful services or would it be just enougt to patch 4.1 to 4.1.1 and I can continue to use apex 4.1.1 with modplsql.
Thank you
Kumar

Hi Kumar,
APEX Listener 1.1 (including your 1.1.4 installation) has a different implementation for RESTful webservices. You can access the configuration using APEX Listener's own configuration ("/listenerAdmin").
The new APEX-integrated RESTful implementation is provided with the new APEX Listener 2, which is still in Early Adpoters phase. It comes with a patch for APEX 4.1 to make 4.1 capable of using it as well. See the installation guide for the current EA release for details.
Since APEX 4.2 has been released now, I'd recommend to upgrade to this release instead of patching 4.1 if you don't have anything that would stop you from upgrading. And I expect APEX Listener 2 to be released soon as well, eventhough there hasn't been an official announcement yet.

for that. But I am not able to show it user when he click on the image link.
Thanks,

HI
Azure media services has a RESTful service and a C# SDK that you can use to interact with the Azure Media Services.
Here is the documentation and sample code for calling the Media services and using the SDK:

RESTful Service: Expose BLOB file inside DB as RESTful service ??

Hello,
With Oracle Cloud we can expose the Data as RESTful Web Service, but how about exposing BLOB... we need to generate a link for that file which is stored in the DB.
To make it clearer:
Two Tables:
Properties (Property_ID number PK, Project varchar2(40), Property_number varchar2(20) ...)
Images (ID number PK, Property_ID number FK, content blob,
mimetype varchar2(200), filename varchar2 (200), filesize varchar2 (200))And I would like to expose this query as RESTful :
Select p.property_id, p.project, p.property_number, i.content
from properties p inner join images i on (p.property_id = i.property_id)Usually we use: [url http://docs.oracle.com/cd/E14373_01/apirefs.32/e13369/apex_util.htm#CHDICGDA] apex_util.get_blob_file_src , but that one should be called from a valid apex session !!!!! ( in that query "i.content" should give a link.)
How can we do it ???
Another point, since we expose the data as JSON:
Suppose I have a property with 10 images, then it does not make sense to get 10 rows fro the same property just to give different image. I think we need another level (nested level) for images !!!
I hope that my point is clear,
Thanks in advance ....

Rest service DELETE doesn't work with OSB

Hi,
I am using OSB 11g, I am using OSB proxy to monitor external rest services call. I've created a business service that point to the external rest service and I created a proxy that is routed to my business service. I modified the flow by adding a piplinepairNode -->requestPipline-->stage -->created two assign and created two variable one for the id and another one for the productID. Then I modified the business service flow as follow:
created two insert, one to define the method, which is DELETE and another one to set the relative-URI to the productID variable and I set the response to replace the . in the body with $body, following this post: http://blogs.oracle.com/jeffdavies/entry/restful_services_with_oracle_s_1
When I test it using osb console Execute, I can see my productID variable is set to $inbound and it is passed all the way to the business service, where it should call the external rest service with the relative-URI, which is set to my productID. it doesn't work, I get 404 error, which is undefined, I believe the reason is because business service is trying to call the external rest service with
http://localhost:{port}/deleteProduct and the rest service expect this URL
http://localhost:{port}/deleteProduct/2 or {productID}
can you please help and tell me what I'm doing wrong?
appreciate any kind of help
Thanks

Want to access RESTful Services through Java Program

We are trying to access RESTful Services exposed by Oracle database cloud through our Java code, with authentication enabled for a particular user.
Till now, we have completed below steps:
1) We have a working account with Oracle database cloud (Username – xxx.xxx)
2) We log in using the credentials for above account, and navigate to Oracle Apex ? SQL Workshop ? RESTful Services
3) We create a new “RESTful Service Module” by filling out the details as below:
     Name:                                  SampleTest
     URI Prefix:                            test
     URI Template:                       /getallemp
     Pagination Size:                    25 (kept to default)
     Required Privilege:                 TestGroupPrivilege
     Resource Handler Details:
                Method:              GET
                Source Type:      Query
                Format:               JSON
                Source:               select * from emp
After creating the above module and testing it, it works fine and the data is retrieved in JSON successfully.
The resulting URL for above RESTful Service Module is: https://<HOST_URL>/apex/test/getallemp
Note that “TestGroupPrivilege” is a privilege assigned to the user group “RESTful Services” and the user “xxx.xxx” is a member of “RESTful Services” user group.
4) We are unable to call the RESTful services from Java program. We are passing username and password in request header as basic authentication. But, we are getting: Error 500--Internal Server Error
5) If we change the “Required Privilege” to default i.e. no privileges present on the module, we can get the response through Java code and everything works perfectly fine.
Please suggest us in: How to access RESTful Services through Java code by passing user credentials in HTTP header for authentication. Also let us know if we have to do any settings through Apex, in case we are missing any.

- When we are logging in to Oracle cloud on browser and execute the Oracle cloud RESTful service in another tab of same browser, we are able to get the result. But when executed the same RESTful service from a different browser or java program we get internal server error.
- After investigation, we found that when user logs in to oracle database cloud, a cookie is set in browser with name s “OAMAuthnCookie_cstest-domo.db.us1.oraclecloudapps.com:443” and value as some random token. This cookie is passed in the subsequent requests to the RESTful Service calls when using same browser and as a result, we are able to get the results
- In the Java program, we copied the same cookie with random token in the HTTP Request header and we got the proper response from REST APIs.
- It seems that this cookie is created by an Oracle Middleware tool/server called as OAM – Oracle Accounts Manager, which sends the authentication token after successful authentication and creates the cookie.
- We found that the cookie that OAM creates on authentication is exactly in the same format i.e. ‘OAMAuthnCookie_cstest-domo.db.us1.oraclecloudapps.com:443’. So, we are guessing that Oracle cloud uses OAM for authentication. Please refer to following link for same : http://docs.oracle.com/cd/E14571_01/doc.1111/e15478/sso.htm
Can anyone please suggest:
1.     How to provide authentication to Oracle Cloud REST APIs from java program?
2.     How to pass the username and password in Java code to OAM (or how to communicate with OAM using Java) so that we can receive the unique token from OAM. We can use the token in the further requests? 3.     Also in Oracle cloud white papers , it is mentioned that they support OAuth2.0. But we didn’t find any URLs for same. Can anyone please confirm?
Thanks
~ Neeraj Girolkar

Hi Nilesh,
We tried to connect to Oracle Cloud Database using the way you suggested above, but unfortunately it is not working as well.
Can you let us know the authentication process with Oracle Cloud Database? We found in documentation that it uses OAM (Oracle Access Manager) for authentication. Can you tell us a bit about that? That will be extremely helpful.
Thanks,
- Neeraj

About the Error after applying product key for bing search rest service

For the Project Siena I ve created the product key for Bing search rest service and i applied that product key which is valid even though i got the error when i click TRY button .can anyone please help me to find the solution
There was an error in retrieving sample data. Error : Unable to reach service. Please check if your service connector configuration is valid and you have network connectivity

Hello,
Thanks for your post. I am jotting down few steps to get the Bing search account key (you may have completed many/all of these).
To add Bing Search Service, go to
https://datamarket.azure.com/account/datasets and search for "Bing Search API". After you have subscribed to the service, navigate to "My Data" and click on Use. Click on Show and copy the
Primary Account Key information.
Note if your key contains a special character like / or = then double clicking on the content will copy the key partially.
Make sure you have copied the full key correctly. If the is incorrectly pasted in Siena's Primary Account Key field, you will get the error below:
This is similar to the error you have posted. Since the Primary Account Key is masked you can never be sure the contents are correct. It's best to clear the field and paste the key again.
If you still face the issue, please post your machine configuration (x86/OS) information.
Hope this helps,

InfoPath combined with Excel Rest services gives State service error

Hi
I'm having a problem with InfoPath and Excel Services. I have a InfoPath form that calls Excel to do a fairly simple calculation, but I also have another form at a client that is doing the same calling a much more complicated function.
The error I get is

MOSS StateService threw an exception: A Microsoft SharePoint Server State Service error occurred while processing your request. For more information, contact your server farm administrator.
I have determined that if the user is in the Members group, then it works, but as soon as the user is in another group, it gives the error. I have played around with permission levels, given the user all rights, but it still gives that error.
Does anyone have any idea about what might be the problem? I have thought that it's a problem on the state service, but it isn't configurable. I don't want to resort to put everyone into the Members group, as that doesn't seem to be a solution that will
work with everyone. We are on the June 2012 CU.

Thanks Sergio. I tried that but unfortunately didn't fix the problem. I have given the groups Contribute rights, Full Control rights, create my own custom permission level, nothing works except when the user is in the Members post.
I realised today that the error I posted above is a bit misleading. The error that happens first before that one is this (after removing timestamps and correlations):

The error I first posed is I think the reaction to this exception. The strange thing is that the user can access the spreadsheet fine. When I go to the URL that is used for the rest service and just remove the $format parameter, it displays it fine as a HTML
value.

+ Symbol is not working on ATG Rest Service Request.

When calling loginUser ATG Rest services and passing email id "[email protected]" in the request parameter but the server received the request without +symbol
+symbol is getting replaced with the whitespace.
Request Sent with email - "[email protected]"
Reached in the server - "test [email protected]"
Can anybody explain me why + symbol is getting replaced by white space ?

Hi D.J,
A '+ ' in the query string represent space ' '. If you want to use '+' in query string encode it before send it to server and decode again on server before using it or you can use another symbol instead of '+', if you don't have specific requirement to use '+' in query string.
Hope this will help.
Thanks,
