Consuming Web Services using UTL_DBWS

Hi,
I am trying to call a web service using UTL_DBWS package.
But I am getting this error:
ORA-29532: Java call terminated by uncaught Java exception: [failed to localize] No Deserializer found!
It is failing at this point:
l_result := sys.UTL_DBWS.invoke (
call_handle => l_call,
input_params => l_input_params);
Is this a problem with database or Web Service? How to resolve this?

No awnsers???
I'm having the same problem here....

Unable to call WSS (WS-Security) enabled Web Service using UTL_DBWS

We are attempting to call a WSS (WS-Security) enabled Web Service from PL/SQL using the UTL_DBWS package (see [http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_dbws.htm#CHDIDGJH] ). We are doing this in similar fashion to [http://www.oracle-base.com/articles/10g/utl_dbws10g.php] with calls to utl_dbws.create_service, utl_dbws.create_call and utl_dbws.invoke.
Using this method we can successfully call an unsecured Web Service, but calls to WSS-enabled Web Services fail. We are currently using Oracle Database 10.2.0.3.
The failure we are getting is:
ORA-29532: Java call terminated by uncaught Java exception: javax.xml.rpc.soap.SOAPFaultException:
com.sun.xml.wss.XWSSecurityException: Message does not conform to configured
policy ( AuthenticationTokenPolicy(S) ): No Security Header found;nested
exception is com.sun.xml.wss.XWSSecurityException:
com.sun.xml.wss.XWSSecurityException: Message does not conform to configured
policy ( AuthenticationTokenPlicy(S) ): No Security Header found
Apparently UTL_DBWS does not support calling WSS enabled services, although this doesn't appear to be an officially recognised position. Does anyone know if Oracle are planning to support this soon (if ever)? Looking at Re: Calling WS from PL/SQL using WS-security suggests that support has been considered before, but not yet realised.
Thanks,
Tom

Having raised a Service Request with Oracle support on this, I got the following response from Oracle Development (On unpublished bug [8542959|https://metalink2.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=BUG&p_id=8542959]):
Development has confirmed that WS-Security is not supported through UTL_DBWS. They have also acknowledged that this is not documented and they will change the official Oracle documentation will reflect this fact. From what is being stated, it would appear that there is no plan to support the use of WS-Security through UTL_DBWS in any release in the near future.
So, in short, without developing your own home-grown SOAP request, there is no way to call a WSS enabled web service from within PL/SQL.

Consuming Web Service using WS-Security: USERNAME Token

Hi ABAP Experts,
we like to consume a self defined web service between to SAP systems (ECC6 701/006). Without any security settings the connection is successfully. But we like to setup a message security like USERNAME Token.
The wss profiles are already created by using TX: WSSPROFILE. Therefore we used the templates "SET_USERNAME" and "CHECK_USERNAME". The service user "DELAY_L<sid>" has been generated as well. The problem is in SOAMANAGER we can't find the related configuration (For Provider and Consumer) to set the parameters "PROFILE In" and "Profile Out" like it was in the obsolete TX "LPCONFIG".
Can anybody help me to find out how to configure USERNAME Token using SOAMANAGER.
Thank you very much in advance.
Kind regards
Axel

The program fails at following line of code -

wsdl_document_location => URIFACTORY.getURI(l_wsdl_url),
service_name => l_service_qname);
Web services are SSL.
The WSDL is at https location and needs username/password for access. The username/password to access WSDL are set using UTL_DBWS.SET_PROPERTY
To access the SSL site, I have imported the CA in Oracle Wallet, JVM home and JDK home.
Can anyone tell me what am I doing wrong here. I am not able to even establish connection to web service host.
This is very frustrating - Oracle has no examples on how to access a SSL Web Service (that needs authentication) from Database.
This is effecting our project deadlines ......... any help would be greatly appreciated.
Thanks.

Hi,
I presume your Web Service needs HTTP (BASIC?) Authentication.
All this needs is setting the following 2 properties, which as can be seen, you are setting....
UTL_DBWS.set_property(l_call, 'USERNAME', '<username>');
UTL_DBWS.set_property(l_call, 'PASSWORD', '<pwd>');
This should work as long as your DBWS Callout Utility was downloaded from OTN after June 2008, and it's version is atleast 10.1.3.1.
Following is a sample code snippet that was tested successfully for this :
Declare
l_service UTL_DBWS.service;
l_call UTL_DBWS.call;
l_result sys.XMLTYPE;
l_request sys.XMLTYPE;
BEGIN
l_service := UTL_DBWS.create_service(null);
l_call := UTL_DBWS.create_call(l_service);
UTL_DBWS.set_target_endpoint_address(l_call, 'http://xxx.oracle.com:8888/basic/MyWebService1SoapHttpPort');
UTL_DBWS.set_property(l_call, 'USERNAME', 'username');
UTL_DBWS.set_property(l_call, 'PASSWORD', 'pwd');
UTL_DBWS.set_property(l_call, 'OPERATION_STYLE', 'document');
UTL_DBWS.set_property(l_call, 'SOAPACTION_USE', 'true');

Calling a web service using UTL_DBWS

Hello,
I am trying to call a web service froma PL/SQL procedure using UTL_DBWS. I've been able to use a different method to determine that the web service is working correctly, so I know my problem is somewhere within my UTL_DBWS call. It seems like my call to the web service is not authenticating correctly. What I would like to do is be able to take a look at the XML header that is created by UTL_DBWS based on the parameters I have supplied, in order to ensure that everything is correct. Does anyone know a way to do this?
Thanks,
Jason

ar file and run FloatValue\plsql_grant.sql in the SYS schema."
And in sqlplus, while I try to access the web service, I get this error:
"SQL> sho user;
USER is "SCOTT"
SQL> SELECT soap_callout_wrap_eg.getCircumference(20)
2 FROM dual;

ERROR at line 2:
ORA-29541: class SCOTT.MyWebServiceFloatRTEProxyJPub could not be resolved"
Could somebody please advise me where I might be going wrong? Any help in this regards will be highly appreciated.

Hi,
I presume your Web Service needs HTTP (BASIC?) Authentication.
All this needs is setting the following 2 properties, which as can be seen, you are setting....
UTL_DBWS.set_property(l_call, 'USERNAME', '<username>');
UTL_DBWS.set_property(l_call, 'PASSWORD', '<pwd>');
This should work as long as your DBWS Callout Utility was downloaded from OTN after June 2008, and it's version is atleast 10.1.3.1.
Following is a sample code snippet that was tested successfully for this :
Declare
l_service UTL_DBWS.service;
l_call UTL_DBWS.call;
l_result sys.XMLTYPE;
l_request sys.XMLTYPE;
BEGIN
l_service := UTL_DBWS.create_service(null);
l_call := UTL_DBWS.create_call(l_service);
UTL_DBWS.set_target_endpoint_address(l_call, 'http://xxx.oracle.com:8888/basic/MyWebService1SoapHttpPort');
UTL_DBWS.set_property(l_call, 'USERNAME', 'username');
UTL_DBWS.set_property(l_call, 'PASSWORD', 'pwd');
UTL_DBWS.set_property(l_call, 'OPERATION_STYLE', 'document');
UTL_DBWS.set_property(l_call, 'SOAPACTION_USE', 'true');
UTL_DBWS.set_property(l_call, 'SOAPACTION_URI', 'http://xxx.oracle.com:8888/basic/MyWebService1SoapHttpPort');
l_request := XMLTYPE('<Z_CENTRICITY_GET_DOCLIST

'<I_INCLUDE_OLD_VERSIONS></I_INCLUDE_OLD_VERSIONS>' ||
'<I_INSTITUTION>0001</I_INSTITUTION>' ||
'<I_PATIENT_NR>0000000181</I_PATIENT_NR>' ||
'</Z_CENTRICITY_GET_DOCLIST>');
l_result := UTL_DBWS.invoke(l_call, l_request);
UTL_DBWS.release_call (call_handle => l_call);
UTL_DBWS.release_service (service_handle => l_service);
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line(sqlcode || ' ' || sqlerrm);

Hope this helps,

Exposing and Consuming web service using NWDS

Hi all,
I want to expose and consume a webservice using NWDS.
My java application will interact with the SAP web service to create materials in r3.
I just want to know how to create a EJB project that contains the Web service and deploy on the SAP WAS.
and from the java application how would I access the same.
do I need to AXIS jar ?
How would get The WSDL corrosponding java files ?
I will be very thank ful if you can provide me with the some study materials also.

Loadjava and jpub in web service using UTL_DBWS giving errors - Help Please

Hi all,
Solicit your help in the below-mentioned scenario.
I am trying to access some published web services from 9.2.0.1.0 RDBMS using UTL_DBMS API. I have accomplished the same using UTL_HTTP. I have followed the instructions specified in:
'http://www.oracle.com/technology/sample_code/tech/java/jsp/callout_users_guide.htm#Web_Service_Callout_Utility_Download_'
to prepare the database, download Callout Utility for pre-10g RDBMS (ZIP, 5.68MB), JPub 9.2.0.1.0 Production and OC4J Release 10.1.2 (standalone) and set the environment variables.
loadjava ran successfully for:

And while trying to run JPub using:

J2T-120, ERROR: Illegal option "-endpoint=http://www.webservicex.net/stockquote.asmx" ignored

Any help in resolving these issues will be appreciated. Kindly also advise which api – UTL_HTTP or UTL_DBWS I should go for and why.

It may be better to post this problem to this forum - http://forums.oracle.com/forums/category.jspa?categoryID=24 since this is much more related to loadjava and jpub

500 Error code while consuming web service using HTTPURLConnection

Hi,
I am getting an HTTP response code 500 and an IOException when I run a web service client to invoke a BMC Remedy web service (document based). I am using XML over HTTP to hit the web service as follows:
// For Remedy
soapAddress = "http://www.test-sislhelpdesk.siemens.co.in/arsys/services/ARService?server=bomw041a&webService=WebService_Test";
soapEnvelope = "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><SOAP-ENV:Header><AuthenticationInfo><userName>webservice</userName><password>*******</password></AuthenticationInfo></SOAP-ENV:Header><SOAP-ENV:Body><Q1:OpGetList xmlns:Q1=\"urn:WebService_Test\"><Q1:Qualification></Q1:Qualification></Q1:OpGetList></SOAP-ENV:Body></SOAP-ENV:Envelope>";
soapAction = "urn:WebService_Test/OpGetList";
     URL url = new URL(soapAddress);
     HttpURLConnection connection = (HttpURLConnection) url.openConnection();
     System.out.println ("Connection got");
     connection.setDoOutput(true);
     connection.setRequestProperty("Content-Type","text/xml");
     connection.setRequestProperty ("soapAction", "\"" + soapAction + "\"");
     OutputStreamWriter outputStream = new OutputStreamWriter(connection.getOutputStream());
     System.out.println ("outputstream got");
     outputStream.write(soapEnvelope);
     outputStream.flush();
     BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
     String line = null;
     while ((line = reader.readLine()) != null)
          writer.write(line);
          writer.write("\n");
     System.out.println (writer);
     catch(Exception e){
          e.printStackTrace();
I have created a .NET client proxy which seems to work well.
I am not able to figure out as to why this code is not working. May be something wrong with the SOAP message request I am sending? But I have created this SOAP request message from the log generated for a successful hit. Any help in this regard will be highly appreciated.
The web service is on the internet and hance is accessible to all :)
Regards
Vaibhav

Tried "POST" request method, did not work.
Actually when i hit other web services (created by me) , the code works.
But when I hit a third party web service, it fails returning 500 error code.
How can I extract the SOAP message returned, if any and see thinggs for myself.
I guess there is something wrong with the request SOAP message which I am sending.

Web Services using UTL_DBWS

Hiiiii Guys,
Can you pls give a simple working example of procedure through which we can call a web services. I have tried example given on oracle's site, but it seems its not working.
I have just installed oracle in my PC, so guys pls give me the names of extra JARs which are required
Thanks in advance
Cheers!!!

Your question makes no sense in this forum.
This is the XML DB forum.
XML DB Native web services allows SQL statements and PL/SQL procedures packages and functions to be invoked from any client that understands how to process a WSDL withot requring any additional code or jars to be installed. It is a feature of database 11.1.x
If you are wanting to invoke a Web Service from PL/SQL code then you can do this with UTL_HTTP, again with no jars required..

Return NULL when invoke Web Service via UTL_DBWS

Hi all,
right now, i'm using UTL_DBWS to acces Web Service via database.. but when i'm trying to get data from WEB SERVICE, using utl_dbws.invoke , i got NULL value.
It happened if The result more than Varchar2 / 32767 byte.
i'have tried to change code by :
result := sys.utl_dbws.invoke(l_call, l_input_params);
P_clob := sys.anydata.accessCLOB(result);
The Output IS NULL value even if the data was less than Varchar2 or 32767 byte..
this is my script looks like ::
declare
service sys.utl_dbws.SERVICE;
l_call sys.utl_dbws.CALL;
result ANYDATA;
wsdl_url VARCHAR2(1024);
service_name VARCHAR2(200);
operation_name VARCHAR2(200);
input_params sys.utl_dbws.ANYDATA_LIST;
p_out VARCHAR2(32767);
p_xml XMLTYPE;
p_clob CLOB;
begin
wsdl_url := 'http://127.0.0.1/Exercise/WSDL2.php?wsdl';
service_name :='{urn:hellowsdl}hellwsdl';
operation_name := 'getData';
service := sys.UTL_DBWS.create_service (
wsdl_document_location => URIFACTORY.getURI(wsdl_url),
service_name => service_name);
l_call := sys.utl_dbws.create_call(
service_handle => service,
port_name => null,
operation_name => operation_name
input_params(1) := ANYDATA.ConvertVarchar2('DOCCODE');
result := sys.utl_dbws.invoke(l_call, l_input_params);
p_out := sys.anydata.accessVarchar2(result);
sys.UTL_DBWS.release_call (call_handle => l_call);
sys.UTL_DBWS.release_service (service_handle => service);
end;
Thanx for Any Help

The basics are simple:
- format a valid SOAP envelope
- use UTL_HTTP to make the call
- process the response (typically XML output)
Sample source code in {message:id=4205205}.

Web Services using MAC Dreamweaver

I have been asked to develop a web site UI that
needs to retrieve data from calls to web services developed by a
third party. Adobe provide a very useful tutorial on how to this
for Windows based development but as an 'artist' I use Dreamweaver
on a MAC OS X system and the tutorial does not seem relevent ?
So, anyone out there point me to how how consume web services
using Dreamweaver for the MAC ??? Any coding I have to do will
probably be in C#.

Error running demo PL/SQL consuming web services

I downloaded and installed the code from:
http://technet.oracle.com/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html
on Oracle 9i version 2 (on both Windows and Solaris).
But I got the following error running the local time
demo:
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1022
ORA-12545: Connect failed because target host or object does not exist
ORA-06512: at "XN.DEMO_SOAP", line 72

The error occurs on this line:
http_req := utl_http.begin_request(url, 'POST','HTTP/1.0');
Can anybody tell me what I do wrong? Thanks a lot!
Also, is there any alternative ways to consume web services
using PL/SQL only? Many thanks!

Consuming Web Services in 11.2 does not work (UTL_DBWS)

Hello
i read some documents for consuming web services on the internet , but i get an error when i call add_numbers function as follows:
i connected on WSUSER , then
SQL> select add_numbers(1,3) from dual;
The Error message is:
ERROR at line 1:

ORA-06512: at "WSUSER.ADD_NUMBERS", line 25"
I use the following steps to setup the UTL_DBWS :
1-     Create new user 'WSUSER'
2-     Run the UTL_DBWS scripts ( utl_dbws_decl.sql , utl_dbws_body.sql) on WSUSER.
3-     Execute this command
loadjava -u scott/tiger -r -v -f -genmissing dbwsclientws.jar dbwsclientdb11.jar
4-     Log in as sys and grant these privileges to our new user:
execute dbms_java.grant_permission('WSUSER','SYS:java.util.PropertyPermission','http.proxySet','write');
execute dbms_java.grant_permission('WSUSER','SYS:java.util.PropertyPermission','http.proxyHost', 'write');

Hi.
Looking at the code, it seems it is my article you are asking about.
http://www.oracle-base.com/articles/10g/utl_dbws10g.php
I've just run through it on an 11.2 instance and it works fine for me.
Make sure your server has access to the Internet and make sure the java classes are loaded successfully.

you can use cl_http_client class to make your program to act as http client and post the soap message too webservice. This way you dont need to generate proxy, but you should know the soap message format.
