Sql to access xml web service

Below is a URL to a web service that returns an elevation value given a latitude, longitude, and some other parameters:
http://gisdata.usgs.gov/XMLWebServices2/Elevation_Service.asmx/getElevation?X_Value=-100&Y_Value=34&Elevation_Units=FEET&Source_Layer=-1&Elevation_Only=TRUE
Returns:
<?xml version="1.0" encoding="utf-8" ?>
<double>1616.45603930856</double>
I'm thinking there must be some easy way (maybe extractvalue?) to parse and return the value shown above. But, I just can't figure out the correct syntax.
Is there anyone out there that can help with this or some other way to do this?
Thanks,
Steve

assuming you get this reponse back in an XMLTYPE:
declare
x xmltype := xmltype ('<double>1616.45603930856</double>');
begin
dbms_output.put_line (x.extract ('/double/text()').getStringVal());
end;

Access a web service from pl/sql

I am trying to access a web service from pl/sql. I have downloaded the code from
http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html
But when I try to execute the sql, I am getting the following error:
SQL> @local.sql
Package created.
Package body created.
No errors.
BEGIN dbms_output.put_line(time_service.get_local_time('94065')); END;
ERROR at line 1:

It is failing at:
resp := demo_soap.invoke(req,
'http://www.ripedev.com/webservices/LocalTime.asmx',
'http://ripedev.com/xsd/ZipCodeResults.xsd/LocalTimeByZipCode');
But in the examples that I got from downloading source code, site used was:
'http://www.alethea.net/webservices/LocalTime.asmx',
'http://www.alethea.net/webservices/LocalTimeByZipCode');
This site was not accessible. So I changed to the working site as follows, but still I
am getting the above error.
But I can access this site, if I type in the above address in the address bar of IE.
Can any body help?
I have oracle9i client installed on my machine and able to connect to server thru toad and sql plus.
or IF any body refers me to a good website for the topic of "using webservies from pl/sql" that would be great too!

Accessing external web service with non-constant URL

Hello, all
I am looking in the documentation on accessing external web services, but either I am looking in the wrong place, or the documentatoin is lacking info.
My clients have several web services in the local network (regular services, not DB-based), the have the same interface, but different URL's.
Versions of the DB are 11, 12, and 16.
First of all, I do not see in the specs an option for a non-hardcoded URL. The logic says that this has to be possible, but I cannot find it.
Second, I need to see an example of accessing an XML or JSon based service, I cannot find it in the specs either.
Can anyone point me to a document with examples?
Thank you
Arcady

The following will call a web service with whatever URL you pass in as the argument "myurl". I think that is what you are looking for.
CREATE PROCEDURE cli_test2( myurl LONG VARCHAR )
RESULT( httpheaders long varchar, httpvalues long varchars
URL '!myurl'
To deal with the resulting data in XML, use the OPENXML() function.
eg. To turn an XML list of employees that looks like this:
<root>
<row EmployeeID="102" Surname="Whitney" GivenName="Fran" StartDate="1984-08-28"/>
</root>
into a table of results, you would do this (where xmlgetemplist() is the web service call):
CREATE OR REPLACE PROCEDURE xmlgetemplist() RESULT( httpheader long varchar, httpbody long varchar)
URL 'http://localhost/demo/xmlEmployeeList'
TYPE 'HTTP:GET';
create variable res long varchar;
-- call the web service
select httpbody into res from xmlgetemplist() where httpheader = 'Body'
-- extract the XML elements into a SQL result set
select * from openXML( res, '/root/row' ) WITH ( EmployeeID INT '@EmployeeID',
 GivenName CHAR(20) '@GivenName',
 Surname CHAR(20) '@Surname',
 PhoneNumber CHAR(10) '@Phone');
To deal with the resulting data in JSON, use the sp_parse_json() procedure.
eg.
To turn a JSON formatted list of employees that looks like this:
"EmployeeID": 102,
"Surname": "Whitney",
"GivenName": "Fran",
"StartDate": "1984-08-28",
"TerminationDate": null
into a table of results, you would do this (where jsongetemplist() is the web service call):
CREATE OR REPLACE PROCEDURE jsongetemplist() RESULT( httpheader long varchar, httpbody long varchar)
URL 'http://localhost/demo/jsonEmployeeList'
TYPE 'HTTP:GET';
create variable foo long varchar;
--call the webservice
select httpbody into foo from jsongetemplist() where httpheader = 'Body';
--turn the json result into a structured array of data
-- this step is required because of less structured nature of JSON
call sp_parse_json( 'output_array', foo);
--extract the JSON elements from the output array into a SQL result set
SELECT output_array[[row_num]].EmployeeID as EmployeeID,
 output_array[[row_num]].SurName as SurName,
 output_array[[row_num]].GivenName as GivenName,
 output_array[[row_num]].StartDate as StartDate,
 output_array[[row_num]].TerminationDate as EndDate
FROM sa_rowgenerator(1, CARDINALITY(output_array))
Hope this helps,

How to access existing Web Service

I want to access the web service (SOAP) from java classes.
Can Any body help me by sending sample code providing that how to send my XML content to the existing web service and get the response from that.
I want to further analyse that it is succedded or not from the response of web service (the response is also in XML).
Thanks,
Dipen.

You are in the wrong forum - web services are not available with Sun webserver. Speaking of examples to check out, I would recommend you to install Sun appserver 8.1 or 8.2 and check examples that come with it, specifically in "samples/webservices" and "samples/xml" directories.

           System.err.println(e.toString());
   }I get an "(407)Proxy authorization required" error?

I am also looking for a solution. Does any one know how to do through code instead of jvm settings?
Thanks in advance!

Not able to access SOAP web service data control from adf mobile

Hi,
I am trying to call web services from adf mobile..
I have created data control from external web service and it is perfectlly working on web browser..
But why it is showing an error on emulator??
Is there any .jar file missing in adf mobile so that it is not supporting a web service?
Or is there any other problem? Emulator is connected to network and I am able to run WSDL in emulator's browser..
Please help me to solve this issue..
Thanks,
Laxmi

Emulator is connected to network and I am able to run WSDL in emulator's browser..
Connecting to WSDL in the browser is not the same as connecting to WSDL in an application.
To access a web service from an Android device enable a permission in AndroidManifest.xml that allows applications to open network sockets. Add the following uses-permission element.

I am using Tomcat 5.0.19 . Could anyone suggest a possible solution to the same?
The system works fine when I use a http endpoint.

Hi,
By default, your application tries to connect to the Net directly : if you have to specify a proxy, use either these lines in your code :
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "proxy");
System.setProperty("http.proxyPort", "8080");
Or specify them in the command line with the "-D"option.
Ex : java .... -Dhttp.proxySet=true .... MyApp
Hope it helps.

Support for XML / Web Service Data Source?

Do you know if and when Crystal Reports for Eclipse will support using the XML / Web Service data source? It appears that only JDBC and Java Result Sets are currently supported. I am using:com.businessobjects.integration.eclipse.library_1.0.0.v671 com.businessobjects.sdks.jrc.11.8.0_11.8.1.v671 Thank you! 

Ok, I copied the JARs (such as CRDBXMLServer.jar) from the JRC SDK (from Eclipse all-in-one) onto the Tomcat classpath and got rid of my previous problem. I now get the stack trace below. I also can not find crdb_*.dll files (such as crdb_xml.dll) anywhere on my system other than the service pack 2 rollback directories.

Issue with accessing OES Web services

Hi,
I have a question regarding access OES web services from external application. I am trying to validate the OES WS for Authorization, but I am getting an error - "Error getting response; org.apache.commons.httpclient.NoHttpResponseException: The server failed to respond"
Is there any specific sequence which I need to follow while accessing this web service, such as first the user needs to be authenticated and then access can be determined or like?
Thanks in advance!!

Hi Kevin,
Would you be able to tell me how you generate the web service client? And when you manage to generate the client, does it automatically generate <generated_name>_Stub.xml?
Thanks,
Alfonso Agustinus

Trying to access https web service

Hello: I'm on 4.1.1. I created web service referece for wsdl for http and it worked fine (http://www.webservicex.net/CurrencyConvertor.asmx?wsdl). Now I'm trying to connect to wsdl using https (https://stage.e-verify.uscis.gov/WebService/EmployerWebServiceV23.asmx?wsdl). I went into owm (oracle wallet manager) to create a wallet. I have pointed the apex instance to that wallet. I have completed the wizard to create a report and form on a web service but it is not working.
I hit the test connection, but get no response. I used to get an ACL/Wallet error before setting up the wallet and pointing to it. After setting up the wallet I no longer get that error, but no response either. I then did the Import Trusted Certificate in owm to pull in a PKCS #7 file I grabbed from the https website. But I still get no response. I can try importing the BASE64 certificate, but don't expect it to help.
One thing I notice is that the Username and Password entered when testing the web service reference does not appear in the request. I expect to get a response even if the Username and Password are wrong, but I don't, and they are not even in the request that I can see.
Are there any examples for setting up an https connection using wsdl with apex and wallet?

At first I couldn't believe it would require going to the trouble of installing certificates just to access https web services. A Google search about APEX and SSL web services seemed to confirm it, but apparently that was all just a red herring.
There's one other thing I should mention in case it helps. APEX support for WSDL, even on 4.1, is still a little rudimentary. I've had problems with it on a few .NET generated web services in the past. Machine generated WSDL based on insanely whacky objects built by OOPtards is just too complex for the APEX WSDL interpreter. I'm just imaging the APEX WSDL component being hand forged in a musty corner of a cube farm somewhere and this large sweaty hammer wielding PL/SQL code cutter with his furnace and anvil beating out something to do the job.
If you're feeling brave, reach for your biggest code hammer. There's one more painful option that will certainly do the job. Process the WSDL locally on your desktop and generate your own SOAP envelopes based on that (SoapUI is a good tool for this). Then create a custom pl/sql package to send your web service request along with the envelope substituting any parameters you might need as the request and do what you need with the response. Just beware, here be a dragon convention.

Ws-basic username inside pl/sql procedure published as web service

I'm new to jdeveloper, but been working with Oracle for 13 years...
We have used Jdevelper to expose a pl/sql procedure as a web service using the "Publish as web service..." wizard. We then used Web Services Manager in server agent mode to protect that web service using ws-basic header auth. OWSM does a lookup on the user supplied credentials against our active directory ldap server to determine if the user should be able to call the service. That all works, EXCEPT...
The problem is that the stored procedure runs a query against data protected by virtual private database and extensive audit logs. We need access to the ws-basic credential from within oracle so that we can set the session context and pull the end-user's id for auditing purposes.
Right now, all we know inside the stored procedure is the oracle username used to connect to the database. This is of course different from the one used to authenticate our user in the OWSM layer.
The pl/sql procedure does not have a parameter to specify the user name, and even if it did, there is no way for us to verify that any user supplied parameter matches the credentials used in OWSM.
So, I assume, I need to modify the code generated by the "Publish as web service" wizard and somehow pull the ws-basic credentials (just username) and push them into the Oracle session_context.
Anyone have any sample code or advice on how to get access to ws-basic credentials or even any of the metadata on a certificate supplied to OWSM for authentication/authorization?

I change p_action value ( before p_action => 'alta' ) now ( p_action => '"alta"' )
res := Xxm_Web_Service_Client_Pkg.invoke(p_init_msg_list => FND_API.G_TRUE,
p_url => 'http://198.137.253.178:7777/event/DefaultSystem/clienteService_RS',
p_action => '"alta"',
x_return_status => l_return_Status,
x_msg_count => l_msg_count,
x_msg_data => l_msg_data,
x_req => req)
And the invokation an ESB service from a PLSQL procedure began to work fine !!!
Thanks for all answers

How to access .asmx Web Service using JAVA? Newbie

Hello Experts,
Currently, I have a project where in I have to access a ,NET web service. It is made of C#. I just want to ask how will I start the accessing process? I made this simple equation on how my project is.
Java Project + C#.Net Web Service = Integration
1. Do i need to create a Web Service too for the Java Project? If yes, What are the necessary tools needed for the creation of this Java Web Service?
2. The .NET Web Service is available online. (It is made by other people).
3. Based on the equation, what is the equivalent technology for the + sign?
4. Can you site a concrete example for accessing a web service?

String url = "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl";
     String namespace = "http://tempuri.org/";
     name = request.getParameter("txtName");
     try
          System.out.println("In Internet Service");
          ServiceFactory factory = ServiceFactory.newInstance();
          Service serv = factory.createService(new URL(url),new QName(namespace,"TempConvert"));
          System.out.println("Got Service......");
          Call obj = (Call)serv.createCall();
          System.out.println("Got Call......");
          obj.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,"");
          obj.setProperty(Call.OPERATION_STYLE_PROPERTY,"wrapped");
          obj.setTargetEndpointAddress(url);
          obj.setPortTypeName(new QName(namespace,"TempConvertSoap"));
          obj.setOperationName(new QName(namespace,"FahrenheitToCelsius"));
          obj.addParameter("param1",XMLType.XSD_STRING,String.class,ParameterMode.IN);
          obj.setReturnType(XMLType.XSD_STRING);
          System.out.println("Parameters Set.....");
          Object[] params = new Object[]{name};
          k = (String)obj.invoke(params);
          System.out.println("Result: "+k);
     catch(Exception e)
        System.out.println("Exception is : "+e);
    }But this code is throwing exception that
Invalid Address "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl"I have also tried this URL with Java Proxy. But it showing the same error.
Plz can u tell me how to access .asmx web service ?

How to access the Web Service Browser

Hi,
I need to access the Web Service Browser to generate a Web Service Description.
How can I do it?
I use the follow url:
http://<host_name>:<port_number>/sap/bc/bsp/sap/WebServiceBrowser/search.html?sap-client=<relevant_client>
but I can't say how to determine values for the three placeholders.
Help me please.
THANKS

Hi Andrea,
you can access the web services in sap transaction SICF. Then right click on the
service and choose "test". The hostname is the host on where the sap system
runs.
The port ´number can be seen in transaction SMICM -> shift + F1. Here you can see
the portnumer assigned to the HTTP protocol.
And the client is the sap client (standard client) for which the service is configured.
Hope this helps.
KR,
Andreas
