Urgent Apex Web service

Hi,
I've created the web service in Visual studio 2008. Then I want to create web service reference from APEX. when I use create web service reference from WSDL file it gives me error:
1 error has occurred
* The WSDL document could not be understood by the rendering engine. Click Create Web Service Reference Manually to continue creating a reference for this service.
Does anyone have experience with this error???
Thank you.

I did a google search on your error message - the first sentence in an advanced search for an exact match - and got 4 hits. 3 of them were OTN posts without a clear answer. The fourth was another site with some discussion that may or may not help you is here http://database.itags.org/oracle/46310/

APEX Web Service

Hi All,
I'm trying to use APEX webs service to make a restful request, the built in API is not working for me and I have spent long hours to fix it but could not.
The documentation on this API is little and searching the internet did return much.
basically I'm using PUT to create an object to Amazon s3 bucket and each time I receive Access Denied from Amazon, when I use APEX shared to create Web Service and then use the web service as page process it will work.
So, I suspect that the API is now working properly.
I used the below API:
L_CLOB:=APEX_WEB_SERVICE.MAKE_REST_REQUEST(
p_url => Service URL,
p_http_method => 'PUT',
p_body_blob => My IMG,
p_parm_name => apex_util.string_to_table('Host:Authorization:Date:Content-Type'),
p_parm_value => apex_util.string_to_table(V_HOST||':'||V_AUTHORIZATION||':'||V_DATE||':'||V_CONTENT_TYPE)
thanks,

APEX Web Service parsing error

Hello
APEX is creating an incorrect item for parameters on my web service below.
Instead of creating two items of names "name" PARM_TYPE xsd:string and "stringValue" PARM_TYPE xsd:string it is creating a single input item called
namestringValue PARM_TYPExsd:stringxsd:string

I am running apex 3.1.1.00.09 has anyone ever run into this problem or have any suggestions?
Thanks in advanced

I found a bug in the Apex handling of WSDL files that was verified by Oracle and reported in metalink quite a while back. I don't remember what version of Apex it was, and I don't know whether the use-case was exactly the same as yours or not.
I believe the way I verified the problem was I compared the Apex handling of the WSDL with another WSDL tool and the results were clearly different.
It appeared to me back then that the Apex developers didn't handle the full WSDL standards correctly, and I'm not sure if they've spent more time on making sure that's more robust or not.
Not much help, I know, but thought I'd let you know that I did uncover a bug re: web services handling.

Apex, Web Services, and complex data types?

Hi all,
I was wondering if somebody could explain to me what sort of support apex has for using web services with complex data types, and how data returned like this could be interpreted and stored in the database.
Any help would be aprreciated.
Thankyou in advance

APEX Web Services Proxy Settings

So I have been experimenting with Web Services and I see to have a problem whenever I go through a Proxy Server; I keep getting the error below for the same request that works when I am not using a Proxy Server.
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "APEX_040000.WWV_FLOW_WEB_SERVICES", line 959
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00202: could not open "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" (error 101) Error at line 1I am thinking that perhaps its because the Proxy Server I am using requires authentication; however, I cannot seem to find a provision for username/password when editing the definition.
Home > Application Builder > Application > Shared Components > Edit ApplicationAny ideas?
Regards,
Phiri

Hi Phiri,
the web services call will be made by the database server, so authentication isn't just an issue for APEX, but you would give the host running the database server access.
APEX itself only supports the simple proxy case just to provide the basic functionality.
Depending on which web server you use to host APEX, you might be able to let that host pass your proxy attributes with the request (e.g. when using OHS, you could put the values into PlsqlCGIEnvironmentList), though I'm not sure whether they are forwarded for web service requests automatically or if you have to build your own process to extract the value from the CGI environment and add it to the web service call.
Another option could be to start building the process in your own process right away. The database has the API-package UTL_HTTP which can be used to perform the proxy authentication (utl_http.set_authentication with for_proxy => true)
Have a look on these pages:
- example for a request including proxy and authentication (with the little change to be "for proxy") http://www.oracle.com/technology/sample_code/tech/pl_sql/htdocs/x/Utl_Http_Package_Enhancements/Cr_Using_Utl_Http.htm
- a nice overview on the package methods: http://psoug.org/reference/utl_http.html

URGENT - Deployable Web Service Proxy gets an unauthorized message

Hello Guys!
I had developed a <i>deployable web service proxy</i> that is called from a servlet. The web service is secured by a basic authentication. My servlet instantiates the proxy and I set the stub like the code bellow:
Maintenance myMaintenance = (Maintenance)ctx.lookup("java:comp/env/MaintenanceWSProxy");
MaintenanceViDocument port = (MaintenanceViDocument)myMaintenance.getLogicalPort("MaintenancePort_Document", MaintenanceViDocument.class);
port._setProperty("javax.xml.rpc.security.auth.username", "user");
port._setProperty("javax.xml.rpc.security.auth.password", "password");
But when I call the servlet, an exception is thrown:
407 - Unauthorized
Somebody knows what is happened?
Thanks a lot!
Best regards,
Marcelo

Hello Marcelo,
i've got an impression that the return error code is related to servlet itself.
Was the servlet deployed as a portal application or as pure j2ee (via SDM or via portal support page)?
Are you accesing it through portal framework or by a direct link to j2ee application?
If it is an portal application - you need to set security policy for iView or for the application (depends on the way you use it. Via iView or via direct link)
If it is an pure j2ee application, then you can define your security roles within the project. First of all, check those settings. Second step is done in VisualAdmin, where you map objects from UME to your security role defined in project.
hope it helps.
regards
mz

OAE Web Services Architecture

When calling a web service on a page in Oracle Application Express, is the web service call sent directly from the database server, or is the request handed back to the HTTP server (via mod_plsql), which then makes the call?
If I call a web service directly from a stored procedure, the web service call is made directly from the database server, sitting in a restricted zone, which has created some security-related headaches in the past, which I'd like to avoid.
Any advice on this topic would be appreciated.

Hi,
the APEX Web-Services are implemented with UTL_HTTP -> the database is doing the callout.

Using web services from apex end

Hi,
I'm trying to suspend/delete/resume a particular job scheduled in BI Publisher from oracle apex end.For these I'm using the following web services
1.suspendScheduledReport
2.resumeScheduledReport
3.deleteScheduledReport
when calling
suspendScheduledReportResponse/
resumeScheduledReportResponse/
deleteScheduledReportResponse
all of them are returning true.
although the web service call is being successful, but jobs are not being suspended/resumed/deleted in BI Publisher.
the web service "deleteScheduledReportHistory" is working fine.
The products I'm using:
APEX 3.1.2
BI Publisher 10.1.3.4
can anyone have detail idea of these??
its really urgent.
regards,
joyoti

I recommend you post this in a forum that has BI Publisher expertise, this is a WebLogic Server forum.

Can you please tell me if creating the Web Service Reference for WCF is supported on the “out of the box“ APEX?
Environment information:
APEX 4.0.2.00.07
Database 11.2.0.3
Please note that we have tried it in APEX 4.1.1 from apex.oracle.com and the error there is different, it can connect even to ASMX wsdl.
Thank you.

I don't think that is it specific to just .NET web services. I have tried with a web service created with TIBCO BusinessWorks (Middleware product) that did not work either. The wsdl validated correctly in soapUI, so I think it just must be the implementation of the parser which is looking for some specific format.
When in doubt, go with either the manual reference or with pl/sql using one of the api's.

Bug in APEX 4.0.2 when parsing web service results?

Receiving ORA-19010: Cannot insert XML fragments error in APEX 4.0.2 when trying to create and run a "Form and Report on Web Service" on any Oracle SES 11.1.2 web service operation
Steps to recreate this error:
SES
- Install Oracle SES 11.1.2
- Create a file source against a directory containing files and then crawl
- Verify via the built-in SES gui that you can search and retrieve results
APEX
- Install APEX 4.0.2
- Create a new database application from scratch
- Create a new web service reference:
shared components ->
web service references ->
create ->
based on wsdl ->
UDDI search: no ->
http://[sesip:port]/search/query/OracleSearch?wsdl ->
create reference
(That creates a web service to Oracle SES with the default name of OracleSearchService)
- Test the new web service:
shared components->
web service references ->
test ->
getAllAttributes (or whatever you want to test) ->
test ->
You will see a valid & correct raw XML request and response
- Create a new web service search form/results using the apex wizard in the following manner:
create page ->
form ->
form and report on web service ->
next ->
web reference type: generated from wsdl ->
next ->
web service reference: OracleSearchService. Operation: getAllAttributes (....BUT YOU CAN PICK ANY OPERATION - THEY ALL WILL FAIL. See http://download.oracle.com/docs/cd/E14507_01/apirefs.1112/e14433/oracle/search/query/webservice/client/OracleSearchService.html for documentation for all the SES web service operations).
next ->
next ->
result tree to report on: Attributes (or whatever appropriate for the operation you chose) ->
next ->
select all columns to display ->
finish
- Now run the page, entering nothing or "en" for locale (or whatever is appropriate for the operation you chose) and then Submit
- No matter what operation is chosen, no matter what parameters are entered, always receive "ORA-19010: Cannot insert XML fragments" error!
PS - We can (and have) created and used APEX 3.1.2.00.02 against SES 10.1.8.3.0's web services without issue.

Damir,
I've tried to replicate this on apex.oracle.com, and could not. I sent a JPG file to my Yahoo account using the name 'Report (2011.05.01).jpg', and didn't encounter any issues. The name of the file received on Yahoo was still 'Report (2011.05.01).jpg'.
I reviewed the code in APEX_MAIL. There isn't anything in there that would modify the filename as you suggest.
Is there a chance it's being changed in your SMTP server / relay?

Web Service consumption in Apex 3.1

Hi -
Are there any guidelines on how web services should be built for apex?
I had a sample WSDL one time, which worked for other reporting tool, but did not work in apex. I was getting err message saying '...there is no result tree node...'.
Thanks in advance,
Tom

Hi,
If you are calling web service using PLSQL then definitely DBMS_SCHEDULER will do.
Refer: http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sched.htm
