Web Services: how to make a clean exit?

Hi
My web service tryes to read some configuration information from a properties file and then connect to a database to do some updates. If the connection to the database fails, I can just return an error to the caller but if the properties file is not found it should just exit and be made unavailable for further calls. Is there a method like the Servlet's destroy()?
Thanks in advance

Are you sure you are posting in the right forum? You are posting in Snow Leopard (10.6.x), but your profile shows a G4 with 10.3? Please clarify which version you are trying to get info on and the hardware you are using.

RFC function as a Web service - how to make wsdl type names unique

Hello,
We have a RFC function module, converted into a web service named ZVIEW_AGREEM, which works perfectly. Note that we only have a basic CRM system (Basis 7.31 SP 11), we don't have PI.
There is a client request to create a new version of this web service, named ZVIEW_AGREEM_2 : there is a new field "output_parameter2" in the response. The response type has XSD type named "VAGResult" (that we entered manually in the service definition).
The client also asked us to keep the old web service so that to be able to switch to the new one at a future date.
So, we duplicated the function module, duplicated the DDIC structure, and inserted the requested field, and then we made the web service.
It's okay except that the client complains that his software doesn't accept the WSDL, because we kept the same external type name "VAGResult", and it's different between the 2 web services (in the second, there is the extra "output_parameter2"). Both are assigned the standard SAP namespace urn:sap-com:document:sap:rfc:functions.
Do you know if there is a way to make SAP control the unicity of external type names to avoid having WSDL types with the same name and different structures?
Thanks.
Sandra
Attached is the WSDL of ZVIEW_AGREEM_2; ZVIEW_AGREEM is exactly the same but doesn't have "output_parameter2".

Thanks.
But the question is more about the fact that we may name a type as we want, SAP does not check (VAGResult in the screen capture below, which becomes <complexType name="VAGResult"... in the WSDL). It may be the same name as a type in another Web Service, both types may have completely different structures. It's a problem from a "philosophical" perspective, as these types share the same namespace "urn:sap-com:document:sap:rfc:functions"; the client software doesn't accept that, we have to rename it; I'd like to know whether SAP proposes a way to prevent choosing a name if it's already chosen for another type of different content.

How to make a Cleaning Page

I recently became the Owner of a HP LaserJet 3100 all in one Printer and installed the Software so it will run on Windows Xp.
I am having trouble with the Printing being too light and there are no instructions on how to make a Cleaning Page for XP.
Can Anyone help?
Thanks.

HTTPS and client invocation of web service - how to?

Got some web services that are document and document wrapped. Have generated the
client stubs using <clientgen> ANT task from BEA. Time to run a test against
the web services, but they have to run on HTTPS. When I invoked my web service
using the HTTPS://.... URL, I got this:

Cool. So how do I assign a default CERT to the https client? This is on a developer
instance of WL 8.1. I don't want to run the test on HTTP b/c I need to see how
it works with HTTPS (need to simulate a bona fide downstream user). Any help
is greatly appreciated.
Thanks

Hi Jacob,
Take a look at the simple, one way SSL example [1] however it sounds
like you want to have the client provide a cert back to the server,
implying two-way SSL. You can find a two-way example here [2].

Bruce

11G - XDB Native Web Services - how to create a web service proxy

Hi,
I am working on XDB Native web Services (http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm#CHDDBCHB). I want to create a proxy web service for orawsv service (http://server:port/orawsv?wsdl), which is protected by an user/password
In Jdeveloper 10133:
+ copy orawsv wsdl (http://server:port/orawsv?wsdl) in local file
+ create a proxy web service form the local wsdl (from the wizard)
+ implement the client (http://www.oracle.com/technology/obe/11gr1_db/datamgmt/xmldb2_b/xmldb2_b.htm)
==> OK
In Jdeveloper 11g
+ copy orawsv wsdl (http://server:port/orawsv?wsdl) in local file
+ create a proxy web service form the local wsdl (from the wizard)
+ how to implement the client : there is no method to set a password
any ideas?
Thanks for your help,

I'm working on getting a proxy web service working in 11g and the contents of this thread is close to answering my question.
The web service proxy is accessing a service that requires a SOAP Security header.
In looking at the previous post, I thought that by using the BindingProvider API I could add the security settings. But when I invoke the proxy I consistently get the following error response from the (PeopleSoft) web service: "com.sun.xml.ws.client.ClientTransportException: request requires HTTP authentication: Unauthorized'
In contrast to that error, when I use JDeveloper's HTTP Analyzer, I get a successful response from the web service. Below is what the raw HTTP looks like:
POST https://isiswebdev.services.wisc.edu:7002/PSIGW/PeopleSoftServiceListeningConnector HTTP/1.1
Content-Type: text/xml; charset=UTF-8
Host: isiswebdev.services.wisc.edu:7002
SOAPAction: "CI_U_FA_CSA_STDTA_CI_G.V2"
Content-Length: 548
X-HTTPAnalyzer-Rules: 1
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:ns2="http://xmlns.oracle.com/Enterprise/Tools/schemas/M183895.V1">
<env:Header>

<ns2:EMPLID>012345678912</ns2:EMPLID>
</ns2:Get__CompIntfc__U_FA_CSA_STDTA_CI>
</env:Body>
</env:Envelope>
Here's the Java code that I'm using to try to make the same call:
public void callIWebservice(String emplId){
cSA_STDNT_DATA = new CSA_STDNT_DATA();
CI_U_FA_CSA_STDTA_CI_PortType port = cSA_STDNT_DATA.getCI_U_FA_CSA_STDTA_CI_Port();
Map<String, Object> requestContext = ((BindingProvider)port).getRequestContext();
requestContext.put(BindingProvider.USERNAME_PROPERTY, "UserName");
requestContext.put(BindingProvider.PASSWORD_PROPERTY,"XXXXXXX");
GetCompIntfcUFACSASTDTACITypeShape CiType = new GetCompIntfcUFACSASTDTACITypeShape();
EMPLIDTypeShape emplIDType = new EMPLIDTypeShape();
emplIDType.setValue(emplId);
CiType.setEMPLID(emplIDType);
try {
GetCompIntfcUFACSASTDTACIResponseTypeShape response = port.getDATA(CiType);
System.out.println(response.getCUMGPA());
} catch (M464939V1 e) {
System.out.println(e.getFaultInfo());
But, alas, I just get the ClientTransportException.
Is the Bindingprovider interface the correct way to add the soap security headers? Or am I following the wrong path?
Any help will be greatly appreciated.

PL/SQL web service - how to use XML schema to define inputs/outputs?

Hello,
let us say I want to publish a PL/SQL web service. The package spec that I want to expose is:
CREATE OR REPLACE PACKAGE myWebService AS
FUNCTION loadResults(
    username   IN VARCHAR2,
    password   IN VARCHAR2,
    resultData IN XMLType)
RETURN XMLType;
END;When I use JDeveloper's wizard to publish my PL/SQL web service, the resulting WSDL contains this:
<schema
    xmlns="http://www.w3.org/2001/XMLSchema"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

    <element name="loadresultsResponseElement">

                </element>
            </sequence>
        </complexType>
    </element>
</schema>It is specifying that anything at all can be passed in and out from the two XMLType arguments, which is fair enough: it has no way of knowing what I am expecting and what I shall return.
My question is, how do I tell JDeveloper that actually I want either or both of those XMLTypes to conform to a particular XML schema?

You cannot format the date as a string, unless you do the conversion on the PL-SQL side, before you use it in your WebService mapping. It should be handled as a string.
The only way to convert the XML from SOAP, using this encoding, into literal XML is to apply XSLT to the payload. Not sure why you would like to do this, as the payload should be consumed by another SOAP-awared stack.
Hope this helps,
Eric

Consuming Web Service ( How to pass multiple inputs and retrieve dataset)

I am new to ADF and Web service.
In the current project, I have to consume a web service ( through WSDL).
Created the pages as per the following tutorials.
http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_14/jdtut_11r2_14.html
As per the steps 11, 12 mentioned in the document, I have mutiple fields so I added these code.
Though in the tutorial, it has zip code as the input parameter, but I have three input parameters such as classCode, annualPayroll & fullTimeEmployees.
How to include there input parameters which should be passed to the results page once the command button "Calculate" as mentioned below is pressed.
<p xmlns="http://www.w3.org/1999/xhtml">
<af:commandButton
text="Calculate" disabled="#{!bindings.calculateBasePremium.enabled}"
id="cb2" action="show"/>
<af:setPropertyListener from="#{bindings.classCode.inputValue}"
to="#{pageFlowScope.classCode}"
type="action"/>
<af:setPropertyListener from="#{bindings.annualPayroll.inputValue}"
to="#{pageFlowScope.annualPayroll}"
type="action"/>
<af:setPropertyListener from="#{bindings.fullTimeEmployees.inputValue}"
to="#{pageFlowScope.fullTimeEmployees}"
type="action"/>
</p>
But JDeveloper is throwing error.
Thanks in advance for your help.
Bibs

Questions is how do you pass the variables from the page to the next page.
I have added code so that when the button command is presses, based on the action event, it will be passed to the next page.
When I was adding the Listener event for the items for page flow, it was not accepting action and was throwing error.
Here is the error message:

Labview Web Services: How to 'undeploy' web services

I have created the example web services:
Address Book project in labview\examples\comm\webservices\address book for an example of a Web service that handles post data, streaming output, static content, and HTML forms.
Weather Monitor project in labview\examples\comm\webservices\weather monitor
for an example of a Web service that publishes simulated weather statistics.
Using Web UI Builder, they are always included in the list of available web services when I Import Web Service.
How do I get rid of them?
Solved!
Go to Solution.

Hello,
To remove them from the list, you need to undeploy the web service. There are two ways to do this: you can turn off Web Services in Distributed System Manager or you can delete the Web Service file.
To enable the ability to control Web Services in Distributed System Manager follow the steps in KnowledgeBase 5BLESQW5.
To remove an actively running web service go to C:\ProgramData\National Instruments\WebServices\aws (Windows 7) and remove the directory that has your web service name. Because we also cashe the LVWS files in another location on disk we will also have to remove that to ensure the Web service is not redeployed by the system web server at some other time. Go to C:\Windows\System32\config\systemprofile\Documents\LabVIEW Data\WebServices\Standalone and remove the LVWS file associated with you web service.
Hope this helps!

Web Services: How to get the username token?

Hello everybody,
I wrote an EJB, Exposed it as a web service.
I'm using encryption+username as the inbound policy.
The client is adding a username token to the message.
I understood that the userpassword are checked automatically and I don't need to implement that myself but I need the userpassword from this token for another reason.
How can I get this information in the EJB's code?
Thanks, Adi.

You can get the user from Session Bean's context.
myContext.getCallerPrincipal();
I think you cannot get the password. That way, it would be easy to disguise your WS as another one you could want to crack.
Regards.

Attn Grant Ronald : Web Services How To : Not valid anymore

Hi Grant
The how to integrate web services with Forms uses Jdeveloper 10g to create a stub for the web services which can be called in from Forms 10g. The step by step instructions are based on version 9i. Jdeveloper 10g does not have the same deployment options as 9i version. The instructions have to change.

Web Services are not supported on apex.oracle.com at this time. This is a fairly recent change - just after our upgrade a few weeks back.
I just added a note to our ShowCase app that demonstrated this a few days ago because our Web Services Showcase pages no longer work (but you can download the packaged version of the application and install it locally to see it work).

Rich client & web services, how to avoid unnecessary bloat

Hi!
Im creating a rich client with java. From this rich client I need to consume web services. Now im wondering which web services framework to use in the client. It seems that almost all (axis, xfire, jax-ws) frameworks require 10+ dependency jars.
This I dont like of course because the rich client is going to be distrubuted over network and I would like to keep it as slim as possible. 5-10 MB in dependencies is not ok when rest of the program is 100k...
I guess that everything is going to be different in Mustang (it should include all the needed jars) but i need to support older versions for next x years.
So if anyone knows any suitable solutions please post here. Thanks.

The problem here is the SOAP engine running on Oracle9iAS 1.0.2.2 is a lower version than that running on Oracle9iAS 9.0.3/OC4J 9.0.3.
To get them to interoperate (e.g. 1.0.2.2 calling 9.0.3), you would have to do the following:
1. Build your Web service in OC4J 9.0.3/JDev 9.0.3
2. Deploy to 9.0.3 environment
3. Build a Web service client on the 1.0.2.2 environment, not using any 9.0.3 libraries (see below for a link to a paper to do this)
Conversely if you wanted to call from a OC4J 9.0.3 Web service client to a Oracle9iAS 1.0.2.2 Web service, you would have to do the following:
1. Build your Web service on 1.0.2.2 using 1.0.2.2 libraries
2. Deploy this to a 1.0.2.2 environment
3. Build a client to the 1.0.2.2 Web service using the 9.0.3 libraries
The reason it likely is not working is that it looks like you are mixing two different generations of SOAP libraries.
See the link below for how to build and consume Web services using Oracle9iAS 1.0.2.2:
http://otn.oracle.com/tech/webservices/htdocs/soapr1/ExploreSOAP1022.html
At the end of that paper is a link to another paper showing how to use JDeveloper 3.2 to build a Web service for 1.0.2.2 - it shows how to use its libraries versus the libraries that came with 9.0.3.

Web services : how to measure the volume and numbers WS sent and received

Hello,
I have to know the numbers of WS used (and which one ?) to make some statistics.
Which transactions or tools can I use ?
Transaction WSADMIN is not enough.
Thanks a lot.

At moment we haven't any consulting request open to SAP .
We want use SAP Hana XS because all the datawarehouse data are stored into the Hana Database and at moment we don't have other software like ESP .
The basic idea is to
- Receive the client requests via HTTP REST in the XSJS
- Resolve the request via Hana SQL in pushdown
- Sent the resolved request by consuming an external web services on another server (non SAP) .
we can do all of this task in hana XS but at moment the problem is that the transaction betwen CLIENT/ SERVER XS the remain open...
what do you think about that ?

Web Service, HOW?

I have 5 things:
- A set of XML schemas that are used for messages that fly around on our JMS servers
- An XMLBeans generated API for dealing with said schemas
- A set of MDBs that use schemas and generated API to understand JMS message bodies
- A stateless session bean with some biz logic that also uses the generated APIs.
- A golden-WSDL that closely resembles the stateless session bean interface and uses <xsd:import> elements to reference the existing schemas. (An implementation that just called that SSB would be great.)
Now I'd like to expose that SSB as a SOAP over HTTP web service - preferably using the already generated XML Bean APIs. I'd like to use the JAX-RPC SOAP processing, but plug-in our existing Java <-> XML marshaling code.
The BEA manual "Programing Web Services for WebLogic Server" has only made it worse as it leaves the impression that the ONLY way to do WLS web services is via JWS/JSR-181 annotations. But it appears that I really want is to expose an EJB as endpoint as described by JSR 109/921.
I'd be happy if I could figure out how to get the service endpoint to just pass the soap body as raw XML. Then I could call our existing xml to java marshaling code myself.
We're running on WLS 9.2MP2 on top of Java5. We need the web-service to start a transaction, to bundle into an ear and be deployable to cluster.
Any suggestions or pointers?
Thanks,
- Chris

Can't you just use the SAAJ API that way you'll have controll as to how your SOAP message is constructed?
