Web client proxy question

I generated a web service proxy in JDeveloper 10.1.3.2.
The web service I am going against is a doc/literal type service, and so the response back is a string. I see that a Response_LiteralSerializer was generated, can I use that to get an object from the response string?
I'm hoping to avoid using dom4j to pull out values from the return.

Dennis,
Perhaps the client sections in these tutorials might help:

Client Proxy Question

Hi all,
Initially, when we have created a client proxy in ECC 5.0 with Oracle on Windows,
we have chosen Local File as the WSDL source. We had the WSDL saved locally.
This way we have generated a Client Proxy in SE80.
Then we created a logical port using LPCONFIG.
Since this the default logical port, we just saved it with all the settings imported
from the WSDL definition.
This way the Client proxy was working fine.
The doubt that I have is, later on, if we want to just change the URL under
call paramters in LPCONFIG to the URL of the WSDL residing on some
other server(Non SAP), will the client proxy work?

Vishnu

Hi Gaurav,
Looking at the error below, the binding is happening.
However, there is a return code 503. And SAP is not able to access the
Webservice located at the other server(Non-SAP).

REST Client Proxy Question

Objective: To call REST service from PB12.5.2 Classic application.
Current implementation: Using MSXML and INET objects to call GET and POST methods.
Problem: This implementation works fine until we have bulk calls (like 100K calls to the service in a single session). Sometimes it errors out because the XML sent to the service is 0 bytes (as seen on Fiddler)
Better alternative: Can we create a new PB.NET PB assembly with a REST client proxy and call the proxy function from our PB classic application? Can we build DLL and reference it from our classic application?
Is there any working example of the same?
Bruce - I have seen your example in http://brucearmstrong.sys-con.com/node/2133766/mobile
You talk about calling the WCF service from the classic application, have you tried the REST service call? I have followed the same steps you have mentioned and hit a roadblock when it came to the REGASM command, not sure which DLL to register now that I have 3 different DLLs. I have explained the steps I have taken in this document - http://www.pbgeeks.com/wp-content/uploads/pbnet.docx
Thanks,
Praveen

You notes show:
REST client assembly: CalcPremrequest.dll
Wrapper assembly: restsvc_assembly.dll
The wrapper assembly should already be strong named in the project. The assembly that doesn't get strong named when PB generates it is the REST client assembly. That's the one that you'll need to disassemble to IL and then recompile with a strong key name file in order to give it a strong name. Your document shows you're doing that on the wrapper.
Both assemblies need to be added to the GAC if that is where you are going to have them.
You might start out without signing the REST client assembly, and just using the /codebase argument to REGASM to have it create registry entries that point to the local file location. Once you have it working that way you can then deal with adding the assemblies to the GAC.
The error you are getting may be a result of the wrapper assembly getting corrupted when you attempted to strong name it.

Web Service Proxy errors out

Hi,
I have created web service proxy using Jdeveloper 10.1.3. My Jdeveloper is set to JDK 1.4.2_17. I can compile and run this web service proxy fine from Jdeveloper 10.1.3, but as soon as I deploy this to Oracle AS 10.1.2 on unix platform it errors out. This is the error message it gives. Why it doesn't find this class?

I think that the Web client proxy in JDeveloper 10.1.3 uses Java EE 1.4 libraries which you don't have on OAS 10.1.2.
You might want to look into hosting an OC4J 10.1.3 instance under OAS 10.1.2.

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

Client proxy consuming web service provider using logical port issue

Hi All,
I have a proxy client having a logical port (configured using NWDS) to consume a web service in the provider system.
In the logical port, I have given target address, and logical port name. While moving this client proxy NWDI dev track to Q and prod,
how do I change this target address to point to Q and prod respectively. In other words, even though I am using Visual admin to configure the destination url for the logical port, to point to Q and prod, its still referring to the dev environment provider service after moving the proxy client to Q and prod. What is the suggested approach to take care of this issue
Thx
mike

Hi Michael,
I can only help from that point of view that I believe this question belongs to the forum
Service-Oriented Architecture (SOA) and SAP

Creating client proxy for calling web service

Hello,
I like to call a WebServce from our vendor. The vendor provides me no WSDL document.
Question: Is it possible to create a client proxy without WSDL? I have just the SOAP Request/Response.
SAP ECC 6.0
SAP_BASIS 700 0010
Thank you very much in advance for any helpful answer.
Kind regards
Axel

Hi Axel,
I am working on a program to connect to a external web-service from SAP (R/3 enterprise 4.7) and while searching all the available stuff for this I got this method.
But, I am still facing some other issues and hence doesn't have the whole solution. You have to probably try it out from your side once and see if it helps.
Please refer the following blog.
https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/847. [original link is broken] [original link is broken] [original link is broken]
it describes a method which is not at all using any WSDL file. Instead it uses the CL_HTTP_CLIENT class to pass a SOAP request to the web-service and then get the response.

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.

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

10.1.3.3 JDev web service client proxy: Issue with XSD:anySimpleType

Hi,
One of our Web services XSD elementss has "anySimpleType" as the type:
<xsd:element name="Value" type="xsd:anySimpleType" minOccurs="0" nillable="true"/>
The client proxy is generated using JDev 10.1.3.3. We observed that the corresponding Java object is created with "String" data type:
protected java.lang.String value;
exp.setValue("100");
We need to be able to pass arguments with other simple types as well (E.g. Decimal). We tried changing the auto generated code, but weren't successful.
Any pointers in this regard are much appreciated.
Thanks,
Phani

Hi all,
can anyone please respond to my issue. Its sort of urgent.

Web service client proxy thread safe?

Is the jax-ws web service client proxy and port objects thread safe in Weblogic 10.3.4?
Been searching through the docs but can't find any info on this.

I have searched and it seems that with cxf it's safe to do something like this.
Nobody knows if this is safe using metro?

ABAP Web Service client proxy - generation problems

Hi!
I tried to create an ABAP web service client proxy for many different web services -
for instance some of that listed at <a href="http://www.xmethods.net/">http://www.xmethods.net/</a> .
Almost on 99% of the WSDLs the client proxy generation failed.
For istance "<extension> not supported", or "<message...> must have at least one part",... .
Could anybody tell me what restrictions are to web services you can create a
ABAP client proxy for ?
In the SAP Web AS Java Stack there is no problem at all to generate a
client proxy for almost all of the xmethod-WebServices !
Is the ABAP Web Service proxy generation for production use ?
Regards
Frank Ruggaber
