APEX Listener 2.0 - RESTful Services Failure with 404 - Not Found

Versions used:
* APEX Listener 2.0.0.354.17.05
* Application Express 4.2.1.00.08
* Oracle Database 11.2.0.1
When testing the sample RESTful Service Module oracle.example.hr I always get 404 - Not Found page.
I followed the documentation to install and configure APEX 4.2 and the Listener 2.0. Everything in my APEX installation works fine except RESTful Services.
For example, when calling this RESTful Service:
http://company.com:45678/apex/DEV/xxuapex/hr/empinfo/
I get a 404 page.
The corresponding entry in url-mapping.xml is:
<pool base-path="/DEV" name="od01" workspace-id="xxuapex"/>
where xxuapex is the name of the schema as well as the workspace where the RESTful Service is installed.
Moreover, the corresponding od01.xml, od01_rt.xml and od01_al.xml in the conf directory seem correct.
Any help is greatly appreciated.
Thanks.
Eddie Awad.

Hi Eddie,
+> try the other option base-url of the url-mapping+
I did. No change. Still getting 404.When active it should transform the 404 page into a detailed 404 with a description of what the error is. Just to be sure, this is activated in the defaults.xml file of the APEX Listener as: *<entry key="log.logging">true</entry>*.
You should then see a detailed 404 output in your browser of what's going wrong first of all.
+> Could you post your url-mapping.xml file?+
<?xml version="1.0" encoding="UTF-8"?>
<pool-config xmlns="http://xmlns.oracle.com/apex/pool-config">
<pool base-path="/DEV" name="od01" workspace-id="xxuapex"/>
<pool base-path="/TEST" name="ot01" workspace-id="xxuapex"/>
</pool-config>
Despite using the url mapping script, it didn't map mine correctly and had to edit it manually. It was the use of "apex" that got it to work for me:
*<pool base-path="/" name="apex" workspace-id="workspace-name-here" updated="2013-01-09T20:48:59.75Z"/>*

Saving to file before storing into a database in a REST service

A mobile back-end I am building should receive a larger amount of data (some sensor recordings) from an Android phone. The phone does not have much use of it so it was most efficient to store the data into plain files (SQLite can get quite slow with larger
amounts). Now when we upload the data to a REST service backed with a distributed database, we have another issue. Storing to it takes some time, since it is really a lot. I thought of uploading the file to the web service as fast as possible, leave the phone
alone, cache the file somewhere on the server and then some long-running workers will pick the data up and chunk it into databases. We have some other mechanisms to verify the data is properly stored and so on, but that is not important.
I would like to know is the REST->file->database approach valid? My concern is where to store the file? Disk, some in-memory database, a cache? Web servers fail (we can request a re-upload, but I would rather mitigate the risk earlier), or the server
can get cluttered. I'm afraid the local storage on the web servers does not scale really well, if we have multiple workers and servers.
Thank you in advance.

You could save the data to a local file like people have indicated and then upload to storage as a blob, alternatively you could also write directly to Table Storage. We have getting starteds for both of these here:
http://azure.microsoft.com/en-us/documentation/services/storage/ - just click on the Java tab.

Issue with 'SAVE AS' RESTful service call in 4.1 SP5 ?

Hello Everyone,
I'm facing an issue when trying to save a webi document into another folder using 'SAVE AS' RESTful call, it's giving 500 Internal server error (through AZOT & RESTClient)
Following are details:
We are on to BusinessObjects version 4.1 SP5. In the AZOT workflow, I have created a new document and in the next call I'm trying to save this newly created document into another folder, then this is error is observed.
RESTful service URL:- [POST] : /documents/{docId}
Request Body:
                         <document>
                            <name>Testing SAVE AS</name>
                            <folderId>219060</folderId>
                        </document>
Response:
Can anyone help me with this ?
Thanks,
Ram

Hello,
Thanks for your prompt replies.
@Saritha:
1. On new document Save call is giving message as "NOT Modified", as i didn't perform any actions.So Yes, I'm able to perform SAVE.
2. Yes, I have performed other operations like creating a Report.
@Eric: 3. Yes, the folder which I'm trying to save is writable for the user.
My Observation: When I'm trying to 'SAVE AS' on new document its giving 500 error as I said earlier.
1. But, after creating new document, I created a new Report for that document, then 'SAVE AS' working. That means after performing some action/modifying the document 'SAVE AS' is working for me.
2. Same issue(500 error) observed when trying to perform 'SAVE AS' call on the EXISTING document as well (which is create in BI Launchpad, refreshing and working fine).
So, is it mandatory to perform any action (which brings the document to Modify mode [i guess]) before this 'SAVE AS' call ?
Thanks,
Ram

An error occurred querying a data source - with REST services

Hi,
I have a SharePoint 2013 form library library with an info-path form. I need to get the logged in user's 'Display Name' on my form load automatically.
I used REST service to fetch the current user details. In the preview mode of the form, its showing the right name. But when I publish this form to library I am getting the following error.
REST Service --> http://site url/_api/SP.UserProfiles.PeopleManager/GetMyProperties
Please help me to resolve this issue.
Thanks in advance for your time and reply :)

Hi,
According to your post, my understanding is that an error occurred querying a data source with REST services.
It is defiantly permission issue with GetUserProfileByName service
and could be many reasons of this problem. You first try with UDCX file and make sure that UPS is running.
Here are some similar threads for your reference:

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

Problem with BPC 10 REST SERVICE. (Write-Back BAdI)

Hello!
We have implemented a Write-Back BAdI order to write values to a parent and copy those values to their children in the hierarchy. Proper operation.
Then through the Default Logic we are making various calculations (many to be honest), based on the data recorded with the Write-Back BADI.
The problem arises when we try to write in a parent hierarchy with many children.
We receive the following message in Excel.
We have configured the service as follows
The transaction st22 says nothing about our problem.
If I go to log the EPM Add-in for Excel see the following. A problem with REST service (I think that is the PROBLEM)
Write-Back BAdI writes values properly.
Thank you!

Thanks for answering.
Yes, if I try to write in a parent without Default.lgf there is no problem. I performed the test to the parent node of all hierachy.
I send the Default.lgf and the others scripts .
I think the problem is that the communication between BPC and Netweaver is lost, which is done through the REST service??
thank you very much.

Hi Experts,
I am doing a sample for Rest Service in smp.
http://192.168.1.119:8086/Test/services/Products
I am calling the above service in the smp it is pulling the data from the service with GET Http Method.
Now i want to call this service for login functionality.
http://192.168.1.119:8086/Test/services/auth?uname=:uname&pass=:pass
here :uname &:pass values are argument values for the uname & pass.
the output of the service is

RESTful service with EJB 3.1 endpoint cannot be found (404)

Hi,
I have a Resource configured as a EJB 3.1 Stateless Bean. I also have an overridden Application class to customize the context root. However, the client just cannot seem to find the Resource. What am I doing wrong? The Resource is packaged and deployed as a war.
Cross posted: http://www.coderanch.com/t/546565/java-Web-Services-SCDJWS/certification/RESTful-service-EJB-endpoint-cannot#2480046

I figured this out...the context root is NOT the one specified in the @ApplicationPath annotation. The context root has to be specificed in the vendor-specific dd, glassfish-web.xml for example, or the default needs to be accepted.
The endpoint URI is of the form http://hostname:port/contextRoot/applicationPath/path, where applicationPath is specific with @ApplicationPath and path with @Path.

[OSB1031] how to call a RESTful service from OSB with authentication

Hi all,
I called successfully a RESTful service from OSB.
We have a business service, named OrderTracer, that wraps the call to the RESTful service.
The RESTful service requires an authentication so we are trying to find out how the OSB business service should authenticate itself against the RESTful service.
In addition the RESTful service accepts username/password coded as base64.
So we defined a Service Account with static resource type and we added the reference to this service account in the business service.
But when the OSB business service calls the RESTful service, we got an error:
<fault>
<con:fault xmlns:con="http://www.bea.com/wli/sb/context">
<con:errorCode>BEA-380000</con:errorCode>
<con:reason>Unauthorized</con:reason>
<con:location>
<con:node>RouteNode</con:node>
<con:path>response-pipeline</con:path>
</con:location>
</con:fault>
</fault>
Does anyone have any hint ?
Any clue would be of great help.
Thanks in advance

Issue with calling restful services via HTTP in an Orchestration

The company I work for is using RESTful services for our I/O. We are processing EDI files using Biztalk, and are calling the REST services via HTTP from a c# code called within the orchestration. At lower volumes, the service performs fine, but at higher
transaction volumes, the HTTP calls never return. Is there a resource that needs to be tuned somewhere on the biztalk node to allow higher volumes of HTTP calls? Its not the REST service side - it has no problems handling loads generated by non biztalk nodes.
For further clarification, the EDI message is a multi batched, so there are many simultaneous orchestrations running at once. I have started to look at ways to throttle how many instances can run at once, but I still suspect some resource in the HTTP
sequence that we dont have enough of.
Ideas?

I think you were not enough free threads in the ThreadPool to complete the operation.
So you can work out with Max connection setting in your BTSNTSvc file first
<system.net>
<connectionManagement>
<add address="http://name.of.server.here" maxconnection="1oo" />
</connectionManagement>
</system.net>
and try increasing number of threads allocated to the specific send Host instance and your Orchestration instance ,you can try twinkling Response timeout in minutes as well on host instance
Thanks

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.

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.

ESS/MSS custom services or modify standard service with WebDynpro Abap

Hi all,
what's the procedure to modify standard ESS/MSS or create new service with WebDynpro Abap.
Thanks.
Miki

Hi
First, The ISR Scenarios are not for iviews. They are just a part of a view. We can use webdynpro ABAP with the ISR Scenarios. We need to embed these forms into our webdynpro ABAP views and code accorsdigly to get the data. There are some standard components that are provided by SAP to handle ISR Forms with Webdynpro. Check these.
