Update table via RESTful webservice

Hi,
I wonder if it is possible to update or insert data with an apex published restful webservice. Whenever I try to test a web service reference with html PUT method I get an 401 - unauthorized.
So is it possible in general to modify and add data to tables with apex published RESTful webservice?
Best regards, Tobias

I believe UPDATE statement would be a better option if it is a ZTABLE(database table), Incase if it a internal table use MODIFY statement.

Insert/Update table via DBLink

I have a situation where the table that I want users to be able to maintain is owned by a different schema on a different database.
TABLE1 is owned by SCHEMA1 on DB1
select,insert,update,delete is granted to SCHEMA2 on DB1
DBLINK is a DBLink from SCHEMA3 on DB2 to SCHEMA2 on DB1
HTMLDB is running on SCHEMA3 on DB2
This setup is necessary because SCHEMA1 is the main data repository, SCHEMA2 has limited access to SCHEMA1 for security reasons, and SCHEMA3 is where HTMLDB is installed
i.e.
SCHEMA3@DB2 --> SCHEMA2@DB1 --> SCHEMA1.TABLE1@DB1
Whenever I try to use the wizards to create a standard Report/Form combo it fails when selecting the table for the Form - table TABLE1 is not in the select list because it's not owned by the schema assigned to the workspace.
So I created a temporary copy of the table in SCHEMA3 and used the wizard to create the Report/Form combo. This works fine.
I then dropped the table from SCHEMA3 and created a synonym pointing to SCHEMA1.TABLE1@DBLINK
The report still works fine but the Automated Row Fetch fails with the error
"ORA-06550: line 1, column 17: PL/SQL: ORA-00936: missing expression ORA-06550: line 1, column 9: PL/SQL: SQL Statement ignored
I presume this is because it's specifically looking for a table owned by SCHEMA3 when in fact it's a synonym.
Is there any way around this without recoding all the optimistic locking, insert, update and delete code?

Doh! After all that I answered my own question ... it's really simple.
Create a view in SCHEMA3 pointing to the table in SCHEMA1 and create the Report/Form based on the view
e.g. CREATE VIEW table1 AS SELECT * FROM schema1.table1@dblink;
(Where's the Delete Post option when you need it?! ;)

Call secure RestFul WebService with basic authorization via https

Hi,
is there a way to call a secure RestFul WebService with basic authorization via https from APEX?
Database: Oracle 11g XE
APEX: 4.2.1
I have a solution by calling the WebService from Java which was called from the database via scheduled job (execute).
As my hosting partner does not support Java I am looking for another option.
Regards
Markus

Hi,
I think its not possible, in this link you can find in more detail why.
Its related with the use of wallets to acess https requests.

Updating database table via program

Hi,
I am updating a DB table (Sap standard table) via my program.
I have few doubts with regard to same. They are given below,
1. I came to know that it is not best practise to update the sap standard table via program using "update" statement. Why so? Is there any other way or statement in doing the same?
2. The sap standard table which i update via my program is BDRGIN. Now my question is, when my program is modifying the values of the table, if some other user also modifies the value at the same time via SE16 then conflict occurs. How to resolve it? Is SAP uses any automatic handling for such conflicts?
kindly help me out.
Regards,
Raghavendraprasad.N

Hi,
Its not a good practise to modify the Standards tables through programs, because most of the standard tables will be interdependant with forign key relation ships (check table relations). So incase we create an irrelavant entry, then it will cause a lot of confusions.
For example we create entries in MARA/MAKT table using MM01/02 transactions.
There are a few standard tables like TVSA (containing customising data), these have to be maintained through the SPRO transaction. You can open SPRO transaction and search for the node to maintain entries in it or you can go to the transaction SM30 and you can give the table name and click on customizng to go the SPRO node.
Still if you are trying to create entries in your table, Enque/Lock the table do the updations and then Deque/Unlock the table, so that there will be no conflicts happening during that time.

Getting OutOfMemoryError with REST webservice

Hi,
I need some help with my configuration regarding
the listener (version 2.0.1.64.14.25 as stand alone with Application Express 4.2.1.00.08):
I consume (via $.ajax(...)) a REST-Webservice for request a clob value.
Configuration of my Ressource Handler:
method: GET
Requires Secure Access: No
source type: "Query one Row"
Pagination Size: 1
Source: select id, col3 from csvloader where id = :ID
This works as excepted until I want to load a value that is bigger then 65 kb.
In my cmd box, where the listener is stated, I noticed the following error:
22.03.2013 14:18:49 oracle.dbtools.rt.web.WebErrorResponse internalError
SCHWERWIEGEND: Java heap space
java.lang.OutOfMemoryError: Java heap space
("SCHWERWIEGEND" means "fatal" in german)
In order to avoid this error, I tried to increase the heap space:
java -Xms500m -Xmx1024m -jar apex.war
-> no change, still getting OutOfMemoryError (HTTP 500 Errorcode)
Any suggestions, hints?
Thanks for your help!
Michael

Hi!
I'm still working on this topic. I updated the listener to the newest version 2.0.2.133.14.47
but this is not a solution for my problem.
Steps I've done:
- raised JVM-Memory: GlassFish -> JVM configuration -> JVM options: add/set "-Xmx1024m" and "-XX:MaxPermSize=256m"
- raise "-Xmx1024m" to "-Xmx1224m" -> glassfish doesn-'t start
Maybe I have a problem with my os: I use windows XP (32bit) in a virtual machine. Seems that JVM don't get enough
memory. On the other hand, I just want to get about 65 - 72,5 KB from a blob-field to my browser....
Any suggestions for me?
Thanks a lot!

Url service data control - problem while POSTing to a restful webservice

Hi,
I am trying to call a restful webservice to add a new employee .I have created the url service data control. The service method consumes XML.
When i am creating the url service datacontrol I selected the http method as POST and giving the servicepath and servicename as the source. After providing the xsd's path and all , when I test the url connection, I am getting the following error message:
URL Test: Received Error: Method Not Allowed
This might be because the clicking of the test url button is sending the get request, but the actual method is POST.
Now under the data controls navigator, If i view the newly created data control, i could see the loadData(Object) method which i assume is for retrieving the data from the service. But since i have mentioned the method as POST, why such a method is created? Also if its there, can I use the same for insert and update? I have used this loadData (Object) method to create a button which calls the webservice upon click. Under the data control property inspector, i changed the supportsupdate attribute's value to true. But when i am trying to save the employee from the jspx page, I am getting the following message in the integrated weblogic's log
Couldn't get access to the data source. Cause Unsupported Media Type exception in rest service
And on the server side I am getting the following error message:
No message body reader has been found for request class Employee, ContentType application/octet-stream.
I think the request is not going as XML. But while creating the datacontrol i have specified the xsd document for the iput xml request. Does ADF automatically creates the XML from the input parametres? If it does not, then what could be done to achieve that? The default actionListener of the submit button is #{bindings.loadData.execute}. Do i have to override it to send the XML request? Or have I missed anything in trying to achieve what i intend?
I had refered this link for reference :

Hi Frank,
I had specified the HTTP method as POST as well as PUT. But the same error is appearing in the both the cases.
URL Test: Received Error: Method Not Allowed
And when I am clicking on the 'Test URL Connection' , I can't see any option of selecting the HTTP method. This option only appears in the step 2 of creating the URL service data control where we mention the URL endpoint and the source.
What could be the reason for the error.

Always check the access_log and error_log files of the Apache web server in such a case. This will identify whether the error comes from Apache itself, mod_plsql, the Apex run-time engine, or the Oracle database.
I see that you're creating a HTTP/1.1 in PL/SQL - however, the web server response indicates a HTTP/1.0 call was received. Unusual. And could be part of the problem.

Restful Webservice -- Page Not Found

Using the web service wizard in SQL workshop, I have created a simple Restful web service using a GET request of Media Resource Type. The SQL statement gets the mime_type and a blob value from a table via an ID parameter. The code works fine in my standalone environment (apex 4.2 Listener 2.1) but on the Cloud, when I bind the variable :ID and press the test button, it always returns, "Page not Found". Even when I call the ws via APEX_WEB_SERVICE.MAKE_REST_REQUEST, it returns, "Page Not Found".
The test screen creates the following URL: https://database-xxxxxx.us1.oraclecloudapps.com/apex/export/get/1
If I run this in the browser, it also returns "Page Not Found". Looking at the URL, it doesn't look correct. Usually, the workspace is also a part of the url (after the /apex/ piece). Here it is missing. However, even when I add it, the error is still "Page Not Found". I have verified that the workspace has Restful web services enabled and I'm logging in with the admin user who has all three SQL Dev permissions granted.
Has anyone seen this before? I'm I missing some permission or doing something wrong?
Thanks,
Steve

Hi Steve,
+> The code works fine in my standalone environment (apex 4.2 Listener 2.1)+
Just to clarify things, Oracle Application Express Listener 2.0.1, which I assume is the version you have installed locally, is the latest Listener release available and is currently running on the Cloud. Oracle Application Listener 2.0 adds support for connecting to more than one database, and includes support for a number of different strategies for routing requests to the appropriate database, each of which is outlined in the Listener Installation and Configuration Guide (see http://docs.oracle.com/cd/E37099_01/doc/doc.20/e25066/config.htm#CBDCHGDF). All strategies rely on examining the request URI and choosing the database based on some kind of match against the URL, and depending on the chosen strategy, the URL will differ.
+>... when I bind the variable :ID and press the test button, it always returns, "Page not Found".....The test screen creates the following URL: https://database-xxxxxx.us1.oraclecloudapps.com/apex/export/get/1+
To assist in pinpointing the cause of the error you're seeing, could you please confirm whether the following details match your RESTful service:
* URI Template: get/{id}
* Resource Handler Method: GET
* Resource Handler Source Type: Media Resource
* Requires Secure Access: No
* Source (matching the following syntax): select mime_type, blob_column from table_name where no = :id
NOTE: if you need to set a bind variable for a parameter, then the "Set Bind Variables" option should be used instead of "Test".
+> Usually, the workspace is also a part of the url (after the /apex/ piece).+
In your local environment, the requests are being routed via the Path Prefix setting in the RESTful Service URL (see http://docs.oracle.com/cd/E37099_01/doc/doc.20/e25066/config.htm#CBDJIEGH). On your local instance, navigate to Administration > Manage Service, Set Workspace Preferences, and in the SQL Workshop region you'll find the Path Prefix item. The Path Prefix defaults to the short name of the workspace, which is what you're seeing in your URL locally. However, a different routing method is being used on the Cloud, so you will not see the Path Prefix used there.
Would you mind testing the 'oracle.example.hr' sample RESTful Service in your workspace, and let me know if you experience issues running any of the examples?
Regards,
Hilary

Restful webservice Internal Server Error PUT POST DELETE

Hi ,
When I make a RESTful webservice on the Oracle Cloud with a PUT,POST or DELETE method, the test results is always the same error: "500 - Internal Server Error".
The GET method causes no problems and gives me the value in JSON format.
Can anyone help me because I can't find an Oracle example with one of these methods?

Java Cloud Service does support RESTful WebServices based on JAX-RS 1.1 specification & Jersey 1.9 implementation.
Please follow the documentation for http://docs.oracle.com/cd/E23943_01/web.1111/e13734/rest.htm#CHDCGFCH (Section Using the Jersey JAX-RS Reference Implementation)
The required Jersey 1.9 shared library is pre-deployed in all the Java Cloud Service instances , you only need to add the reference of this shared lib in your weblogic.xml.
The following example shows how to update the weblogic.xml file to use the Jersey JAX-RS RI Version 1.9.
<library-ref>
<library-name>jax-rs</library-name>
<specification-version>1.1</specification-version>

Restful Webservice and German Umlaut

Hello,
i'm trying to setup a restful webservice using Apex 4.2 and Apex Listener 2, but i have problems regarding german unlaute in the json response.
To see if its a configuration error on my side, i did setup an exmaple on apex.oracle.com and there i get the same results.
I added a now row to the table emp, with just the ename as 'öäü'.
Please see the example at http://apex.oracle.com/pls/apex/dwtest/getEmp/
The result looks like this:
{"next":{"$ref":"http://apex.oracle.com/pls/apex/dwtest/getEmp/?page=1"},"items":[{"ename":"Ã¶Ã¤Ã¼"}]}It should look like this:
{"next":{"$ref":"http://apex.oracle.com/pls/apex/dwtest/getEmp/?page=1"},"items":[{"ename":"öäü"}]}The interesting fact is that i sometimes get the desired output, but its net reproducible to me. As browser i tested Firefox, Chrome, IE9 and Opera.
I wonder if i configured something wrong in my browsers or in apex.
If you would like to take a look at the webservide use these credentials:
Workspace: dwtest
Username: testuser
Password: forum
Thanks for help in advance.

Dirk

RESTful webservice in BPEL

Guys,
Is it possible to connect to AWS server through RESTful webservice in BPEL 11g.
Please share your thoughts. Thanks

On each published web service you have the different operations that can be performed on this service.
If you have a look et the wsdl-file of your web service the endpoint location, you can test if everything has been deployed correctly by accessing this webservice via Enterprise Manager in your Oracle Soa Suite installation.
Can you try to test the webservice via the testing console provided in EM?
Kind regards,
Nathalie

Report data ( value ... tag) missing in the Webi report retrieved through RestFul Webservice

I am trying the below URL to get the WEBi report from SAP BO using the Rest Webservice support that is now available.
http://{serverIP:serverPort}/biprws/raylight/v1/documents/{documentId}
I am able to get the report but as I compare the same report response when using SAOP Webservice, there seems to be a mismatch in the response. Here is what I see in the SOAP response:
</td><td c="1" ><cell ref="1.E.4t" bid="14" h="26" w="231" pad="6,7" sid="-10"><ct >Some arbitrary value</ct><value type="xs:string">Some arbitrary value</value></cell>
But when I run it through REST, I am missing the <value ..> tag:
</td><td c="1" ><cell ref="1.E.4t" bid="14" h="26" w="231" pad="6,7" bt="1" sid="-10"><ct >Some arbitrary value</ct></cell>
Apart from this right at the start of the xml response, I see some property mismatch as well.
SOAP has this property extra:
<property name="output.format.xml.valuemode">yes</property>
While REST has these property extra:
<property name="output.format.xml.option.style">1</property>
<property name="output.format.xml.styledict.fontplatform">html</property>
<property name="output.format.xml.td.bandinfo">yes</property>
<property name="source.selected">data</property>
<property name="xelement.xml.object">yes</property>
<property name="xelement.xml.object.usemap">yes</property>
<property name="xelement.xml.object.usersupportedformat">image/png</property>
I am not sure if:
the <value ...> tag miss is because of these missing/extra properties or
current REST support has some issues
For my application the value tag is a must and I can't do without this, but with REST it seems no way to obtain that.
Any help or pointer(s) in this regard is appreciated!

Hello Milind,
According to our Product Owner Sam Polichouk, the solution should be available for you in 4.1 SP3, which is currently scheduled for release by the end of March 2014 (subject to change). The product team recommends that you get the raw, unformatted data values from within the Dataset specific call. This data contains a type to tell the end user what kind of data it is, so you can format it or use it properly.
The updated documentation for the SDK will be available at SAP BusinessObjects Business Intelligence platform 4.1 – SAP Help Portal Page once the Support Pack is publicly released.

Bapi in order to update table T056P

Hi all,
Is there any bapi or fm to update table T056P in order to enter interest reference rates values.
Thanks and best regards

Dear Marcelo,
Thanks for your help, but we are adding new values to this table via transaction Enter Reference Interest Values (S_ALR_87002678), Accounting-> Financial Accounting->General Ledger-> Enviroment-> Current Settings->Enter Reference Interest Values. With these values, afterwards we run ff_1 in order to calculate interests on bank accounts. We don´t have anything else on this sense and the process you mention seems to be for Treasury when you have further elements on this module. I don´t know if it´s worthy and how to do it (where customize) in order to change from executing S_ALR_87002678 to tj05 and tj13. Would this improve our process and also have another transaction instead of ff_1 which is an old transaction that doesn´t allow our users many possibilities for calculating interest on bank accounts.
Thanks for your help and regards

REST Webservice invocation from Java

Hi Guys,
I am developing an application that needs to invoke a REST webservice and submit XML data to it. The server will then process the request XML data, and return a result, etc.
I have never worked with REST and have spent hours researching it on the NET. I have done SOAP calls in the past, but this seems to be eluding me some what.
Does anyone know of any useful links that explains REST implementation, frameworks / jars needed, or possibly even an example or two that shows me how to submit data via REST to a URL (would be first prize :) ).
Any help would be greatly appreciated.
Many thanks
Mark
