Distributing Oracle Web Services Proxy client?

Hi,
We built a web services client using Web Services Proxy tool in JDeveloper. We want to distribute it as a stand-alone application to our clients.
1. How can we determine the minimal set of JAR libraries required for the application to run?
2. Are there any licensing issues?
Thanks!
Simeon

If you are not using any ADF libraries there is no licensing concerns.

Web service proxy client with client cert cause SSLSessionNotFoundErr

Hi,
I tried to run web service proxy client with certification from JDeveloper 10.1.3.0.4 to call PKI enabled web service got folllowing error:

Invoke Bpel Processes via API or Web Service Proxy Clients

Hi all,
I was wondering if any of the felow community members have found information regarding best practices in invoking bpel processes from a user interface other than ADF Faces?
Currently I'm using Web Service Proxy Clients to invoke my bpel processes, but I was wondering if it would be better to use the BPEL API?
Considerations I have regarding these 2 different approaches are mostly tight integration when using the BPEL API, because this means I have to port the BPEL (Oracle Code) inside my UI-application which isn't the case when using Web Service Proxy Clients.
What is the best way to instantiate bpel processes from a user interface, is that by using web service proxy clients or by using the bpel i
nvocation API?
Kind regards,
Nathalie

Hi Marc,
These were my considerations as well, but I was looking for some kind of benchmarking regarding these 2 approaches. What's best practices when hooking up bpel inside UI Applications regarding performance, future-proofness (SOA Grid, SOA Composites, ...) etc.
I think I need to discuss this with the product team to make sure I'm taking the wright decisions.
Kind regards,
Nathalie

Web Service Proxy client to invoke a Web service on SSL (Jdev 10.1.3.1)

Hi,
I have to develope a Web Service proxy client to invoke a web service on SSL. First I'm testing with OC4J 10.1.3.1 and JDEV 10.1.3.1 and did this:
1) Developed a basic PL/SQL Web Service with JDEV and publish on my standalone OC4J.
2) Made a test with a browser, it worked OK
3) Generated a proxy client from JDev 10.1.3.1 to invoke web service, it worked OK
--- Now make it work on SSL----
4) Then, added SSL configuration to oc4j , generated a certificate with keytool (updated server.xml, secure-web-site.xml), and shutting down and starting the OC4j instance.
5) Import the certificate to JAVA_HOME/jre/lib/security/cacerts
6) Test web service from browser on https and worked OK.
7) When tried to modified proxy client (generated in step 3) to make it work on SSL, I realized that just changing the END_POINT to the new url (https) it worked!
Questions----
1.- By default the proxy client generated from JDEV 10.1.3.1 knows how to deal with SSL conections?
2.- If I dont have previously the server certificate to import it into JAVA keystore (cacerts) how could I ,from proxy client code, capture it and import it before the validation occurs... because if the certificate is not in keystore , the program fails.
Thanks in advance
J.

Hi,
Could you please provide me with the steps necessary to create a web service proxy client through JDeveloper or any other mechanism when 2 way SSL (requiring client authentication) is enabled.
Thanks a lot in advance

Web service proxy client from Oracle DB

I need to call an external webservice from oracle db... but this web service does not support "SOAP with attachments" and its specification says that we have to develop a J2EE proxy client to access this web service, this still could be done in a stored procedure, loading jdeveloper generated code in java?, I know that with Jdeveloper I can generate a 'web service stub/skeleton' but how make this stub accesible from oracle with PL/SQL? is this possible?
thanks in advance

How to use server-side classes in a web service proxy client ?

Greetings,
I'm using WebLogic 10.3 with Workshop 10.3 on Windows. I generate a Web Service client in Workshop. There are two options in the New->Others->Web Service category: ClientGen Web Service Client and Web Service Client. I've chosen the second one as it's a JAX-WS Web Service and I think that the first one (ClientGen Web Service is to be used with JAX-RPC Web Services. The proxy is generated but, since the Web Service is using POJOs as parameters, a new version of these POJOs is also generated. For example, my Web Service has an operation like: public OrderStatus putOrder (Order), where OrderStatus and Order are application scoped POJOs. The proxy generation process generates a _PortType class which is supposed to be used by the calling client. This class defines an operation public OrderStatus putOrder(Order), but the OrderStatus and Order classes aren't the original ones but the generated ones. The issue is that these generated classes aren't completely equivalent to the original ones, for examples all lists become arrays, the constructors are different, etc. This is extrememly annouying. Is there any option to say to the proxy generation process to keep with the server-side classes ?
many thanks in advance for any help.

The only solution to this problem seems to be using dynamic proxies. But it doesn't work neither as the following code:
Service service = Service.create(new URL("http://localhost:7001/OrderServiceProject/OrderService?WSDL"),
new QName("http://www.simplex_software.fr/demo/services", "OrderService"));
OrderService orderService = service.getPort(new QName("http://www.simplex_software.fr/demo/services", "OrderServicePort"), OrderService.class);
raises the following exception:

As a matter of fact, fr.simplex_software.demo.services.OrderService is not an interface but, nevertheless, it's a SEI and it was generated as it is by the IDE Web Service wizard. Big, big confusion ! Of course, this sample works perfectly with Metro, in NetBeans using Glassfish.

Web service proxy client generation fails

Hello,
i want to generate a webservice proxy client of a web service. For the access to the wsdl file of this web service, basic authentication is required. How can i use the proxy generation tool with username and password? The wsa.jar -genProxy doesn't work because i dont know how i can submit username and password. Is it possible to integrate username and password anywhere?? Is there an other way to generate a webservice proxy client? Please help me :(
Thanks a lot from Berlin!

Web Service Proxy wizard doesn't open up in edit-mode anymore

I've created a web service proxy project for my existing bpel processes and since the bpel processes server has changed, the endpoint has changed as well.
When I update the endpoint in the <webservicename>_Stub.java file from the webservice proxy client everything works fine.
But when I try to go back in edit-mode inside the wizard, the wizard complains about the old endpoint url of the bpel process. If I search in the project after that specific hostname, I can't find any file or folder referring to the old url.
Could somebody explain me why I can't invoke the wizard anymore for a web service proxy client if the endpoint has changed?
Kind Regards,
Nathalie

Hi Nathalie,
Which version of JDeveloper are you using?
With the latest release, 11g Tech Preview 2, I don't think you can re-enter the wizard by double-clicking on the service proxy icon on the application navigator tree.
From the context menu, the only option is to edit handlers, add custom mapping, security or reliability.
I have found that using ant-based tasks is a better way to get predictable and reproducable outputs, even if the learning curve is not easy.
Here is just a snippet to give you a concret sample:
<target name="genproxy">
    <delete dir="./gen_src"/>
    <o :genProxy wsdl="http://${endpoint.host}/pge/webservice?WSDL" output="./gen_src"/>
    <o :genProxy wsdl="http://${endpoint.host}/pge/webservice?WSDL"
                mapheaderstoparameters="true" databinding="false" output="./gen_src"
                packagename="com.selectg"/>
</target>Hope it helps,
-Eric
I add an extra space in the XML, so that the o: prefix is displayed in the XML snippet

Dynamic wsdl for web service proxy

Hi,
I have generated the Web service proxy client based on wsdl used in dev env,
if i have to deploy to production, i have to manually change the WSDL url to point to production.
Is there anyway, I can deploy without changing manually.
thanks

thanks all from the prompt replies.
I still have a query. All i can do is create various WS references in connections.xml and call dynamically. like
Context ctx = ADFContext.getCurrent().getConnectionsContext();
WebServiceConnection wsc = (WebServiceConnection) ctx.lookup("MyConnection1"); // here i can make a dynamic call ...
but this piece of code can work only in UI. what if i need to do the same approach in model from my AM.
Is there a way ??

Problem with Oracle Web Service Proxies reusing classes and exceptions

We have an application that have many web services and we're having a really hard time working with Oracle Web Service Proxy. We have many web services that share the same classes for parameters and exceptions. When we generate de proxy classes, it generates a lot of _LiteralSerializer classes. Because I'm reusing the same classes and exceptions it generates the same _LiteralSerializer classes for this classes and they get replaced. For Example
I have classes A and B and Web Services X and Y that use this classes. When I generate the 2 proxies it generates A_LiteralSerializer and B_LiteralSerializer on the 2 proxies and they get replaced and I get "No serlalizers for A class or B class". This problems repeats a lot of times and this problem is a huge risk for our project. We're using JDeveloper 10.1.3.4.
Is there a way to avoid this with Oracle Web Service Proxies?
Regards,
Néstor

Resolved when I create a deployement profile explicitly.
The Webservice.deploy that gets created automatically when I create a web service was giving this issue.
Thanks

Test web service proxy using EJB session bean client...

Hello!
I am following this blog /people/abdelmorhit.elrhazi/blog/2009/10/30/how-to-consume-an-inbound-backend-web-service-in-nwdsjboss-environment to create a EJB session bean client to access the web service proxy...
The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
How to find out the URL for the wsdl ?
Thanks

> The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
"To deploy your web service proxy and session bean, right click on your JBoss server in the Servers view, and click on Add Remove Projects, add you ear file and click finish."
You need a JBoss server.

Oracle.classloader.util.AnnotatedNoClassDefFoundError Web Service Proxy

I have seen this issue being posted a couple of times, but I have not seen any solution yet...
I created a dynamic web service proxy using JDeveloper's dynamic proxy generation feature. I got it to work in both j2se and j2ee. However, when I tried to migrate the code to jdev on a different machine, I got this error:
oracle.classloader.util.AnnotatedNoClassDefFoundError:
Missing class: com.raytheon.winsight.proxy.StructureListType
Dependent class: java.lang.reflect.Array
Loader: jre.bootstrap
Code-Source: unknown
Configuration: jre bootstrap
And the weird thing is that it works when I run it as a j2se executable, but does not work when I try to run it in a servlet. Does anyone have any idea? Thanks!

I believe so. I am running it in my jdev environment with its own jdk/jre.
Another thing I have noticed is that in the jdev environment that is not working for me, every time I attempt to launch the ws proxy, I get the following error:
"2007-05-31 09:43:01.406 WARNING Warning: cannot load wsm config file: com/raytheon/winsight/proxy/runtime/WSEnumSvcSoap_Stub.xml
2007-05-31 09:43:02.516 WARNING Warning: cannot load wsm config file: com/raytheon/winsight/proxy/runtime/WSDataSvcSoap_Stub.xml"
I looked into my original jdev project that is working in the j2ee environment, and could not locate those two xml files...
