Error creating a Web Service. Help!

Hi, I'm triying to create a web service but when I try to test it or execute, it gives me this error:
ORA-20001: The webservice was unreachable because either the URL you supplied was invalid, your environment requires a valid proxy server address for HTTP requests, or a wallet needs to be configured for HTTPS requests.
Error testing service.
The syntax is correct. The problem is that I can't create or config a Wallet, I read the tutorial to create a wallet but I can't upload it.
Please I need help.

Want to give it more than 3 minutes after asking before you expect an answer? No kidding it isn't answered yet!

Errors creating a Web Service Proxy using Microsoft WSDL.exe tool

I have deployed a BPEL process using JDeveloper. This process can be invoked from the BPEL console and completes as expected. I am trying to create a Web Service Proxy using the Microsoft WSDL.exe tool so that the process can be invoked from a Microsoft Word document. This process is based on the AutoLoan example in the Developer's Guide for Microsoft Office Interoperability B25781-01.
WSDL.exe returns the following error message
Error: There was an error processing 'http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl'.
- The document at the url http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl was not recognized as a known document type. The error message from each known type may help you fix the problem:
- Report from 'WSDL Document' is 'There is an error in XML document (19, 7).'.
- A schema with the namespace '' has already been added.
- Report from 'DISCO Document' is 'Discovery document at the URL http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl could not be found.'.
- The document format is not recognized.
- Report from 'XML Schema' is 'Expected Schema root. Make sure that the root element is <schema> and the namespace is 'http://www.w3.org/2001/XMLSchema' for an XSD schema or 'urn:schemas-microsoft-com:xml-data' for an XDR schema. An error occurred at , (2, 2).'.
How do I resolve this error?

The WSDL file is below.

Error creating a web service in NWDS SP18.

Hello,
I created a web service DC. It works fine when I test this with Web Services Navigator. I get the output as expected. But when I test it with Enterprise Portal Web Services Checker in NWDS, I get this error:
"The SOAP Message returned is not well formed
com.sap.engine.services.webservices.jaxm.soap.accessor.NestedSOAPException: Unable to create message from source"
When I tried creating a web service using a simple J2EE-->EJB Module project, added to an EAR project and deployed, I see the same error. In both cases am able to successfully test on Web Services Navigator...
Any body let me know how to create a web service in NWDS SP 18...
Thanks

Error creating a web service standalone proxy

Hi all,
I'm new with Sap Netweaver Developer Studio (SNDS), so sorry if the question is too easy.
I wuold create a stand alone proxy for a web service created by a function module in R3.
I follow the help of SNDS but the project doesn't compile. The error is
This compilation unit indirectly references the missing type com.sap.engine.lib.xml.parser.tokenizer.XMLTokenReader (typically some required class file is referencing a type outside the classpath) ZhrWsStrAnagInd2.java AnagIndStandAloneProxy/src/com/capitalia/webservice/anagind/types/p1 line 0
Where I can find this package? or the problem is another?
thanks for any help,
enzo

Hi Enzo,
Add <Install folder of Netweaver developer Studio>\SAP\JDT\eclipse\plugins\com.sap.tc.ap\comp\SAP_BUILDT\DCs\sap.com\tc\bi\xml\_comp\gen\default\public\def\lib\java\sapxmltoolkit.jar to classpath of your project (hope you know how to do it).

Error creating a web service client from th WSDL document (soamanager)

Hello everyone,
we have generate with the wizard a web-service using the function module BAPI_CONTROL_RECIPE_GET_LIST. Then we have generated with SOAMANAGER the end point. As test, we have used a web-service explorer of Eclispe and we can retrieve without problems the data.
Then we wanted to generate the web-servcie client with Eclipse Galileo (3.5.0) wiith the server GlassFish v2.1 Java EE 5 we first installed the WSIT jars, in order to support WS-RM protocol
We have started the generation based on the document obtainend within the soamanager under the "Open WSDL document for selected binding" link.
We have tried it several times and we always got the following error is:
IWAB0399E Error in generating Java from WSDL: WSDLException (at /wsdl:definitions/wsdl:portType/wsp:Policy):

Do you know if we took the right document in order to generate the web-service client? Do we need to have some specifics settings in the configurations of th endpoint? (provider security, transport settings, etc...?)
If needed, or if someone would be nice enough to try to generate it on its side, I can post here the whole wsdl document, but due to its length, I first wait your comments.
Thanks a lot in advance for your feed-back
best regards

addtions:
maybe this should have been better posted within the forum Service-Oriented Architecture than standards?
I forgot to mention the following threads, which seems to me to be somehow in this direction. But I do not get really how I could use them, or how is is releated.

Security Error when creating a web service with Flex

Hello comminuty.
I'm using Flex to create a standalone application and I have to use web services to retrieve data from SAP.
I used the bapi bapi_flight_getlist to create an associated WS that works fine (tested with the Eclipse's WS Explorer).
In Flex Builder, I use the following code to create my web service:
     <mx:WebService
          showBusyCursor="true"
          id="service"
          wsdl="{wsdl}"
          result="resultCreateWSHandler(event);"
          fault="faultCreateWSHandler(event);">
            <mx:operation name="FlightGetList"
                 result="resultWSHandler(event)"
                 fault="faultWSHandler(event)"></mx:operation>
        </mx:WebService>
And this is the error I'm getting:

Guys,
You are asking about an issue that was a pain in the nick for me few months ago. The problem is that you won't find mych help here as I figured out that Apex geeks here either did not do much webservices or ended up hating it as i do :) . This is an error that can be due many different reason, let me ask you this:
1- Does your the other system you are trying to call through webservices using HTTPS ?
2- If yes, did you create a valid oracle wallet for that https connection ?
3- Make sure you are using the correct URL ( am sure you do, just double check )
4- If using a proxy, then you have to define that in the web service reference creation page
provide more info and I hope I can help you with this,
Sam
Please reward good answers by marking them correct or helpful!

Do you have java stack installed along with your ABAP on this

Creating a web service for F4 help

Hi All,
I want to create a web service that I can consume using JavaScript and thus can integrate with normal HTML web site. I want to achieve this by two ways
Pass table name and field name to the service and it will return the default search help
In some cases search helps are collective search helps and they have search criteria to filter data
How can I tackle with the 2nd point. First one looks straight. Pass table-field and the system will pick default DDIC search help and return values in table. However in case of collective help, I need to cater for the search parameters and I am not aware of any FM that will allow me to do it.
Any help appreciated .

Hi Marcin and everyone,
Thanks for the precious explanations.
I created a client and I have an exception.
1) I made a portal service from wsdl - client side.
2) I created a DynPage.
3) Here is the code :
IMyBAPI4Service client = (IMyBAPI4Service) PortalRuntime.getRuntimeResources().getService(
IMyBAPI4Service.KEY);
IMyBAPI4Service securedClient = (IMyBAPI4Service) client.getSecurisedServiceConnection(                 request.getUser());
//this is null.
if (securedClient.getURLEndPoint().getURL() == null) {
securedClient.setURLEndPoint(new URLEndpoint("http://<server>:<port>/irj/servlet/prt/soap/com.sap.portal.prt.soap.MyBAPI4Service?style=doc_lit"));
Bapi_Companycode_Getdetail_Input importParams =     new Bapi_Companycode_Getdetail_Input();
importParams.setCompanycodeid("0500");
Bapi_Companycode_Getdetail_Output exportParams = null;
securedClient.execute_BAPI_COMPANYCODE_GETDETAIL(importParams);
Do I have to use a secured client ? What is it ?
The exception is :
Problem at execution: SOAP Fault Error (java.lang.NoClassDefFoundError) : java.lang.NoClassDefFoundError
Thanks Marcin....

Hi,
Can anybody tell me please, is it possible to create
a Web Service from java class where the input from
user is required ?Yes, the parameters of your method will be mapped in WSDL.
But i've some considerations about your code.
I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.
Regards.

Please Help! Unable to create a web service.

Hi all,
I have created a deployable proxy, a EJB with a stateless session bean, and a enterprise application project with the above ejb added. I add the deployable proxy into ejb, so that i can utilize the interface(web service) provided by the external party. After i implement the code to call the web service from external party in stateless session bean, i should create a web service by right click on session bean>New>Web Service. However, nothing was happened while a pop up window of web service creation wizard should appear. NWDS showed "End Point Doesn't Exist" when i tried to create the web service by File>New>Others>Web Service>Web Service (New VI and WSD).
Anybody have any idea of it? Your help will be apperciated.
Warmest Regards,
Jane

Frustating errors while creating java web-service

Hey All
Me getting a frustating problem while making the webservice using Eclipse, jdk1.6.0_03,and Tomcat-5.0.
The overall scenario is like this.There is a class “WsEpp” of which I have to make webservice.”WsEpp” class is using the object of another class “EppService”, and if certain conditions will be fullfill then “EppService” class will use the object of another class “PrintClass”,which is allready using the object of class “PrintLib”.
“PrintLib” class is a long file and its using many classes which are in supported jar files.
Here is the some part of “PrintLib” where I am facing the problem,
Scenario-1
public epp_Command command_data = new epp_Command();
public PrintLib()
System.out.println("CONSTRUCTOR 1");
this.command_data = new epp_Command();
System.out.println("CONSTRUCTOR 2");
Here I am using the constructor of the “PrintLib” and “epp_Command” is included into jar files.When “WsEpp” is running as web service then
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>java.lang.reflect.InvocationTargetException</faultstring>
occurs as the response of webservice.
Scenario-2
//public epp_Command command_data = new epp_Command();
public PrintLib()
System.out.println("CONSTRUCTOR 1");
// this.command_data = new epp_Command();
System.out.println("CONSTRUCTOR 2");
When I am commenting the lines as shown in scenarion-2,then the service is running well and printing CONSTRUCTOR 1 and CONSTRUCTOR 2 as given in println command.
And response of webservice gives the desired result.
Scenario-3
public epp_Command command_data = null;
public PrintLib()
System.out.println("CONSTRUCTOR 1");
this.command_data = new epp_Command();
System.out.println("CONSTRUCTOR 2");
By using scenarion-3 the service is running and printing only CONSTRUCTOR 1 as given in println command.And also
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>java.lang.reflect.InvocationTargetException</faultstring>
occurs as the response of webservice.
I am suffering with this problem from last 2 weeks.Kindally help me and provide me the some suggestions and tips.In case of any more requirement I can provid ethe whole codes.

Web Service help - ORA-30625: method dispatch on NULL SELF errors

Hi All
I could do with some assistance getting Web service's up & running on my application
I've been following this guide but altering to fit in with our internal web services... the Internet police here at work have youtube blocked off so unable to test end to end using the OTN tutorial
I've created a web service named PASSWORDGEN with the results stored in the collection PASSWORDRESULT
On my page I've created the process that invokes the webservice PASSWORDGEN which is set to run on load - before header - seq #10
then created the pl/sql anonymous block process which is set to run on load - before header - seq #20
I've used the pl/sql example given in the tutorial but substituted their references to collections with my named collection .
declare
l_clob clob;
l_xml xmltype;
l_val clob;
begin
for c1 in (select clob001
from apex_collections
where collection_name = 'PASSWORDRESULT'
) loop
l_clob := c1.clob001;
exit;
end loop;
l_xml := xmltype.createxml(l_clob);
l_val := dbms_xmlgen.convert(l_xml.extract('/methodResponse/params/param/value/string/text()').getclobval(),1);
apex_collection.update_member_attribute(
p_collection_name => 'PASSWORDRESULT',
p_seq => '1',
p_clob_number => '1',
p_clob_value => l_val );
end;
if I try to run the page at this point I get the error ORA-30625: method dispatch on NULL SELF argument is disallowed
what I think is happening, from what I've read up on, is that the collection is empty?
so I'm trying to find out if the web service is not populating the collection correctly or have I made a mistake in the above syntax & trying to reference the collection incorrectly.
Is there a way I can query the collection using TOAD?
Edited by: Mr JD on 21-Jul-2010 08:38

ok so found the collection but when I invoke the web service the collection record is not populated. I've tested the webservice & a result is returned but for some reason when I either run the test or run the page which invokes the web service as a page render process the collection is still not populated.....
what I'm I missing here as the setup of the web service is pretty straight forward & testing the web service does produce a result within the test window
