Generating web service from session bean

Hi
I have a session bean in one project which has a service-endpoint defined.
My web services are in another project entirely, within the same workspace if that helps any.
When I generate the web service from the EJB JDev turns the business tier project into a web project,
I don't see any options to include the web service in the web project.
I've reversed all of the changes, but wonder if I shouldn't redo it and copy the mapping file and configuration
across to the web project and reverse the changes in the business tier.
This is a workaround that I'm hoping to avoid, as I'm doing the "howto" for this in our project.
How is this normally done?

I tried generating the web servioce from WSDL, in the web project.
I tested and the web service works fine.
Then I changed the config file to point to the ejb, but the server won't start up....
*08/09/17 10:58:40 WARNING: Application.setConfig Application: current-workspace-app is in failed state as initialization failed.*
This is the webservices.xml bit I updated...
<ejb-link>SomeOrOtherEjbName</ejb-link> The bit I found in webservices.xml when the service is in the business tier.
 The service that works in the web tier.

How to use WS-RM web Service from Session Bean?

Hi all.
Could you tell me the way how to call WS-RM web service(Staring BPM Process) from SessionBean?
Our environment: SAP NetWeaver CE 7.2 SP3
I do the following.
I have created a BPM Process starting with Message Start Event.
This Message Start Event was created by Service Interface(stateless and asynchronous) which was imported from ESR.
I deployed this into my server and it worked fine in webservice navigator as a WS-RM WebService.
But I can't call this webservice from SessionBean in EJBExplorer.
I get the following error message:
Caused by: This exception is wrapper of javax.xml.ws.soap.SOAPFaultException. com.sap.engine.services.webservices.espba
se.client.bindings.exceptions.SOAPFaultException: Invalid WS-RM message. There are no WS-RM headers within SOAP message.

I created this SessionBean as follows:
I created DCs for EJB and created SessionBean in EJB DC.
I imported a WSDL file(WS-RM web service) from Service Registory and
I created service clients and Service References.
After that I implemented SessionBean to call web service checking with this help.
http://help.sap.com/saphelp_nwce72/helpdata/en/44/4d2bb1c6b00597e10000000a155369/frameset.htm
After deploying this EJB,I configured properties in nwa.

Did you manage to solve this? I'm doing something similar and seeing the same problem, although they're up to 7.3 SP7.
Any help greatly appreciated.

Problem invoking gogle web service from session bean

Hello
I have developed a Web-Client which consumes the google-WebService with Apache Axis. I have generated the corresponding classes with WSDL2Java and the client works without problems. A little code fragment from my client:
GoogleSearchService service = new GoogleSearchServiceLocator();
          // Now use the service to get a stub to the Service Definition Interface (SDI)
          GoogleSearchPort google = service.getGoogleSearchPort();
         GoogleSearchResult googleSearchResult = google.doGoogleSearch(GOOGLE_KEY, // java.lang.String key
                       q.toString(), //java.lang.String q
                       0, // int start
                       10, // int maxResults
                       false, //boolean filter
                       "", // java.lang.String restrict
                       false, //boolean safeSearch
                       "lang_ja|lang_en", // java.lang.String lr
                       "UTF-8", // java.lang.String ie
                       "UTF-8"); // java.lang.String oeNow I have to put the Web-Client in a SessionBean. Therfore I defined the code of the web-client in a method and put it into a stateless session bean and wrote a client for the session bean. But when the session bean invokes the corresponding method for consuming the google web service, there always occurs the following error:
[java] Exception in thread "main" java.rmi.ServerError: Unexpected Error; nested exception is:
[java] java.lang.NoClassDefFoundError: GoogleSearch/GoogleSearchService
But I have definitely all necessary classes in my classpath, like GoogleSearchService, etc. So all necessary classes are available. And the code to conume the web service als works because as said I tested it with a web-client.
Has anybody an idea what went wrong here? Is there anything important when I a web service is invoked by a session bean??:(
regards
pat

Has nobdy an idea?? :(( I tried for such a long time but I was not able to fix this problem....:(

There is no any error message show up. It just the class
Z_BAPI_ATTACHMENT_CREATE doesn't create autometically as normal. I showed you as below.
That means I can't call class z_bapi_attachment_create.

I generated web service from function module.Where can I find .wsdl file ?

Hi,
I generated web service from function module.
Where can I find .wsdl file ?
I want to use .wsdl file in .Net application.
Thanks.

Hii Cemil Bozlagan,
All Remote enabled Function Modules in Web AS 6.20 and Above are available as Webservices and the WSDL documents are available in the web service repository at
[http://<host>:<port>/sap/bc/bsp/sap/webservicebrowser/search.html]
Find the respective BAPI.
Click on the WSDL link in the browser and download the WSDL document and use it as per the requirement

Create a web service from java bean and map exceptions to SOAP faults

Hi,
We have to expose our Session stateless EJB3 as web services. I've tried to use annotations and jdev wizard "java bean to web service" and it works fine.
Our problem now is that our methods can throw a business exception that contains a list of error message strings to be presented on the client.
I did not find any way to use annotations to make it build a wsdl with soap fault mapped to our exception class. Neither I could to make the wizard to create wsdl with faults.
As we are exposing already designed and implemented classes as web services, I think the bottom-top (java->wsdl) approach is better that top->botton (wsdl->java). Therefore, I'm looking for a possibility to generate the web services from the java beans and have the exception be mapped to a soap fault message.
We are using jdev 10.1.3.1 and OAS 10.1.3.1., is there a way to map exceptions to soap faults using bottom->top approach?
thank you

My last question concerning web services:
I have already written a session bean and I'd like to add some methods
as a web service to it, how do I do that?
Or I can only create another bean for a webservice and cannot modify the
original one?You might create web service with existing sources and select you bean. New web services with appropriate lookup method will be generated.
All web service method, that will be exposed in web service, you
should add itself (Pop-up menu Web Service -> Add operation)

Error while generating Web Service from a function module.

Hi Experts,
I am trying to create a web service from function module by doing the steps as mentioned in the below document:
http://www.sdn.sap.com/irj/scn/index;jsessionid=(J2EE3417800)ID1146834250DB10778842957931285337End?rid=/library/uuid/80fa3dff-ce76-2a10-3f94-f3df8f2db5a2&overridelayout=true
When i save it as an local object instead of generating the Web Service it gives me the below error:
"Error during activation of Web Service"
Kindly let me know what needs to be done inorder to resolve this issue.
I have a feeling that this error may be with respect to some authorizations, in that case how do we resolve it
Helpful Inputs Awaited.!!!

Generating Web Service from PL/SLQL procedures using ODSI

1) Is there a way for us to generate REST based web services from PL/SQL procedures using Oracle data services Integrator? If Yes, Can you please point me to any available documentation
2) I am trying to create a phyiscal data source based on PL/SQL procedures in the hope of turning these data sources into web services. I created a JDBC connection in web logic server console and am trying to view the packages under APPS but ODSI always crashes after selecting APPS. Is there a way to resolve this?

Hi..
We came accross this problem a while back (I think it was us that the patch was created for). The patch was released under CR369707.
Additionally it took us a while to figure out how to use it correctly.. Here's the info for it from a mail i receievd from our support contact..
Here is more information from engineering on the patch:
This is patch for filtering Stored Procedures in the New Physical Data Service Wizard. It is a partial fix to the problem. It just does filtering - it still retrieves all the jdbc metadata for everything that matches the filter. Ideally, the wizard would let you explore the stored procedures - retrieving the name only - and once you selected a stored procedure, it would retrieve the argument types (which is the expensive part).
Copy these two files to a safe place
<bea_home>\<aldsp_home>\eclipse-plugins\dsp\eclipse\plugins\com.bea.dsp.ide.external_10.3.0\dsp-ide-ldshredder.jar
<bea_home>\<aldsp_home>\eclipse-plugins\dsp\eclipse\plugins\com.bea.dsp.ide.import_metadata_10.3.0.jar
Replace the files with the ones provided in the patch (which I sent you be eMail recently).
Creating Relational Database Physical Data Services -> Stored Procedures will be affected as follows :
The Search field used to represent a pattern for the stored procedures only, and this patterns were applied against every schema visible to ALDSP. The patch allows you to also specify a list of catalogue patterns (useful only when applicable), a list of schema patterns and a list of procedure name patterns. These lists are separated by the pipe symbol, and the lists themselves are command-separated. The catalogue and schema patterns are regular expressions, the procedure pattern is for a database 'like' clause. For, Oracle, the catalogue patterns are not applicable.
Example:
|ODM1,ODM2|B% // look in schemas containing the strings ODM1 or ODM2 for procedures that start with B
// possible results would be MY_ODM1.BUILDER, ODM2.BOTTOM
|^ODM$|B%D // look in the ODM schema for procedures that start with B and end with D.
Also - if there is a search string in the Search box, that search string will be applied to the schema when you click on the + to expand it in the Tree.
Note that once a schema has been 'explored' - either by a search, or by expanding it in the tree, further searches will not update it's children. You would need to quit the wizard and restart.
Once you get the patch if you have issues let me know..

Invocation of Netweaver generated Web Service from XI

Hi,
I have defined a webservice for a stateless session bean using the developer studio. From the wsdl I have imported the message interface as external definition. I have defined mappings on the respective message type. Now I would like to call my service using the SOAP receiver adapter.
Could anybody tell me which URL has to be quoted there. I retrieve the wsdl from the following address:
http://myhost:50000/AddressService/AddressConfig?wsdl
Since the webservice is RPC like, is it valid to invoke it using the SOAP receiver adapter?
Kind regards,
Heiko

Hi Naveen,
Do you have an answer for this ....
Hi Friends,
I have a question regarding publishing a WSDL created via XI (Integration Directory) to a UDDI Server of SAP WAS JAVA 640. Can I publish the WSDL generated from XI in the UDDI Server provided as a part of SAP WAS 640 ? I know that the WSDL will be specific for a client( sender) but I feel that its better than emailing the WSDL to the client after generating it in the integration directory. Any relevant documents, links explaining how to do that will be appreciated.
The above question was asked by Siva Maranani before. His question was as below .
"I know that whenever a webservice is developed using NDS it can be deployed in WebAs and the same can be registered in UDDI ( webAs acting as UDDI registry).
Now my requirement is to register a WSDL file (which describes) for an external webservice. Can WebAs be used as a UDDI registry..?
I like to know if this is possible or not..? if yes.. how..?"
Waiting for the reply...
Thanks & Regards,
Mathew

Running web service in session bean or Java class

Hi All ,

Thanks in advance

Hi Ravi,
1ce the service is published ..you can execute the service by making the instance out of it or the other option is you can use jaxrpc or saajapi for dealing with SOAP api directly

This is fixed now. Someone had defined a Servlet for the web service in web.xml that was preventing the EJB container to kick in.

Parameter names change when generating web service from WSDL

Hi,
I have a problem with BEAs web services that I'm hoping someone can help me with.
I have a
WSDL file, and from that I want to generate a web service implementation and a
web service
client. In the WSDL file, I have a message defined like this:
<message name="someRequest">
<part xmlns:partns="http://www.w3.org/2001/XMLSchema" type="partns:base64Binary"
name="data"/>
</message>
I generate the server using the server using the wsdl2service Ant task, I implement
the necessary classes, and I deploy it. When I access the deployed web service,
the parameter name has changed, from "data" to "bytes". If I access the WSDL file
of the deployed web service, it says:
<message name="someRequest">
<part xmlns:partns="http://www.w3.org/2001/XMLSchema" type="partns:base64Binary"
name="bytes"/>
</message>
This happens for all parameters, string parameters are renamed to "string", base64Binary
parameters are renamed to "bytes", etc...
This poses a problem to me, because if I generate a web service client from the
original WSDL file, it will not be able to talk to my web service. Is there any
way of forcing a web service generated from a WSDL file to keep the parameter
names of the original WSDL file?
Any help in this is greatly appreciated.
Regards,
Petter

From a quick look of your WSDL, it seams that you are mixing document-literal-bare and document-literal-wrapped flavor of web services. WSA may be able to do a better job at working around this mixed flavors than JDeveloper.
If you have hand crafted this WSDL, I would recomend that you spend some time looking at the way WSDL are generated, with the java-first mode (or bottom-up), then author the WSDL you need for the final service.
Here are sample of bare-style :
<xsd:element name="getPupilAddressResponse" type="xsd:string"/>
<xsd:element name="getPupilAddressRequest" type="xsd:int"/>
Wrapped will looks like that:
<xsd:element name="getSENLevelResponse">
<xsd:complexType>
<xsd:sequence maxOccurs="1" minOccurs="1">
