Help about web services

Hi All,
We use jdev 9i for the apps development.
We are integrating many applications to talk to each other and get the data .
For which we are planning to use web services too.
My question is : Is it possible to call web services from OAF using 9i jdev ?.
Can any body point me to some docs or tech urls to start with knowing these web services from OAF.

See this thread in this reference.

Hi,
I tested following code using JDevloper 11g
@Resource
    WebServiceContext wsc;
    @WebMethod
    public String webMethod() {
                MessageContext msgCtxt = wsCtxt.getMessageContext();
        HttpServletRequest req = (HttpServletRequest)msgCtxt.get(MessageContext.SERVLET_REQUEST);
        System.out.println("Client IP = " + req.getRemoteAddr());
        return req.getRemoteAddr();
    }It is giving me IP address but when i tested this web service from another computer there also it is giving my machine address instead of the machine IP from where the web service is called.
What is wrong in my code ?
Regards,
Ajay

Help on Web services

Hi
I would like to create a Web DynPro (Java) project using web services and leverage R/3 system for information, but not really sure how web services leverage on the function of R/3 to retrieve and store information. Will be very much appreciated if someone can shed some light on this.
Thanks
Rayden

hi Rayden,
yeah sure there is some concept called as EJB where we can write our business logic instead of calling FM, also RFC calls are considerd as little expensive,
check out some info about them here

A question about web service

hi experts,
I develop a web service based on abap FM. When the 3party programs call it, user need to input the username/password.
can I config sth for the web service, and user don't need the input user/pass?
Thanks

Hi Michael,
I understand you are worried about security (i.e.people accessing the Service anonymously is something you want to avoid). Also, you don't want the people to have to manually authenticate themselves (i.e. enter a User ID and Password) to execute the Service. In this case, you need to use a more sophisticated authentication technique like X.509 SSL Client Certificate or SAP Single Sign On Ticket. This is a complex subject and not suitable for discussion here. Here are links to topics that could get you started.
1. SAP Help Portal link to the topic Security Aspects for Web Services:
http://help.sap.com/saphelp_nwpi71/helpdata/en/46/a088198f835edfe10000000a11466f/frameset.htm

Some question about Web service

Hi experts,
I have created a Web service about Function Module 'BAPI_EXCHANGERATE_GETDETAIL'.Now I plan to use Transaction code 'WSADMIN' to create a WSDL.But the display result of IE tell me my host could not be resolved by DNS.I don't know how to solve this question, and which happened based on this question.Is there any experienced experts tell me the solution?
Thanks & Best regards!

Hi,
In your system folder:
C:\WINDOWS\system32\drivers\etc there is a file hosts;
Add your server I address and servername in it.
like:
193.10.100.70 myserver.com MYSERVER
Hope this will resolve the problem. If you do not have authorisation for the same, your network admin will help.

Expose BAPI as a Web Service
1. Go to transaction SE80.Select Function Group from drop down menu; enter the function group in which the BAPI (which is to be exposed as Web Service) comes. You can find this Function Group from function module (BAPI) itself. Go to transaction SE37 and enter function module name (BAPI name) and click on display. You can see the function group here under attribute tab .
2. Then from Function Modules list choose the BAPI to which you want to expose as a
Web Service .
3. On right clicking on the BAPI a context menu appears. Click on create and Web Service option .
4. New window will pop up. Click on Continue.
5. Give the name for Enterprise service and short description. Click on continue.

Questions about web services and BPEL in ALBPM

Hi all,
We are currently evaluating various BPM products in order to decide which one to use. Currently I am evaluating ALBPM Studio 5.7 and I am running my processes on the embedded engine provided with the studio. I have some questions:
1. We want to be able to use complex types for the web services that are generated for processes. Will this limitation be solved any time in the future?
2. We want to be able to use the generated web services directly (that is, without calling the startSession method first). Is that possible?
3. I could not find extensive documentation about developing BPEL processes. There is only one small chapter in the developer documentation about BPEL processes. Is there any more documentation or sample about how BPEL is used in ALBPM?
4. I have developed a very simple BPEL process, but when I try to deploy it, I get the error "Activity BPEL receive does not have any incoming transitions". How can I resolve this issue? I guess it may be a problem about my PartnerLink definition.
5. When I try to catalog a wsdl which imports another wsdl (and when the imported wsdl also imports some xsds from another namespace), I get an error which says that a web service xxx with namespace yyy is not found, but actually the thing named xxx is not a web service but a soap fault. What could be the problem?
6. Is it possible to write a BP method in PBL for a BPEL activity?
Thanks in advance and best regards..

Help? Web service crashes whenever I check "enable SSL"

Whenever I try to enable SSL for one of my virtual domains, Server admin reports
"A service has encountered an error"
and disables web service for that virtual domain.
Everything was working fine (ftp, webdav, websites, mail).
So my final step was to try to enable secure webdav via https.
So I
* bought a certificate (godaddy $30) for my domain EXAMPLE.COM (no www, since everything is hosted on one box, for email, webdav, ftp we just use "example.com"
* manually pasted my key into /etc/httpd/ssl.key/server.keyx
* manually pasted my cert into /etc/httpd/ssl.crt/server.crtx
* manually pasted the CA cert into /etc/httpd/ssl.crt/ca.crtx
* entered my pass phrase I used when I made the key
* used the log file default /var/log/httpd/sslenginelog
(when crashed the first time I thought the file not being there could be the problem, so I copied another file, and ensured the permissions were the same: owner root, group admin)
all that was fine. checked the enable SSL box, and clicked Save and that's when it reports the error and disables the virtual domain.
My server is 10.3.9.
The first time I used 10.4 admin. When it crashed the service I did a restart on the server, then on the server used the 10.3 admin. Same deal. (Only difference is on 10.4 admin it set my port to 443; on 10.3 it didn't)

I did get it working. But my recollection of what I did to get it working is fuzzy. I think what I noticed is that whatever I put into the various SSL key fields was not getting saved, so I tracked down the appropriate locations and edited them manually. Sorry I don't recall the specifics.
Another thing I do remember is that I was unable to CHANGE an existing "site" setting from port 80 to 443 -- I had to delete the entry, then re-create it from scratch with the SSL settings and PORT #.
Hope that helps.

Help with Web Services

hi,
am trying to call a web service from a particular WSDL, i need to use JAX-WS 2.0 as part of this assignment am currently working on, but i just cannot put my head around it and where to start,,
would i need to just write a client that would call a specific method and pass the parameteres through it ?
would i need to use annotations ? as i was reading, you only use them if you expose the web service. All i was supplied with is a WSDL, and i need to design an interface using JFrame and call a specific service of my choice and receieve a response back.. and display it back.
Any helpful tips, suggestions, sample code ??
thanks

You can easily work with WSDL2Java class in axis.jar found from apache site
java -cp axis.jar:commons-logging.jar:commons-discovery.jar:wsdl4j.jar:jaxrpc.jar:saaj.jar org.apache.axis.wsdl.WSDL2Java -va "wsdl file"
This will create a stub files for the webservice, then you work with that.

Help: using web services

Hi all,
I have oracle content server 10g in a developement enviroment. I want to invoke ocs web services from Bpel 10.1.3.3.
How can I do it?
Thanks,
ale

Are you asking how to do this from the BPEL perspective, or are you trying to learn something about the services in content server? Content Server can accept SOAP calls for any of its services, but it also has a set of WSDLs that other applications can use for discovery of a select set of the services. You can also add to the WSDL's to enable more services. If you go under the Administration menu in your content server and look for SOAP WSDLS you will see these definitions.

Help starting web services

Hi, I am new to web services and after reading a lot of literature on the subject I am completely lost. I am running Axis2 1.3 and I have just got my WSDL2Java to work. I am using Eclipse and now also have the wsdl plugin working.
However the problems I have is that after I create the stub I have many errors, all of which are from missing imports...org.apache.axis2.... I was wondering if anyone has any suggestions for sorting this out. I cant find these files anywhere on my system.
I may have made a mess up ofinstalling Axis but I think its correct. I would really appreciate some basic help/tutorials on accessing a service from the internet suhc as aweather forecast (http://www.webservicex.net/WCF/ServiceDetails.aspx?SID=50) to get me started as i have been trying now for 3 weeks with no luck. I have tried to follow tutorials and code examples but I still have many probelms.
Any help would be much appreciated.
J

Hi,
Im not great with Eclipse and the errors are all to do with org.apache... such as this one: extends org.apache.axis2.client.Stub. It says tehse canot be resolved to a type. I have tried to import the libraries but I cannot find the ones required. It appears all my WSDL2Java createions require this package but I cannot find it anywehre.
Do you know what these are and which ones i need to import?
Sorry its a bit vague, i think/hope im missing some libraries, i just cant locate them on my machine or the web and I am stuck until i get around this problem.
Regards, j
