Help needed regarding web service

I implemented a stateless session bean(also remote and home interface)
and created a jar file for that bean. After that I converted this bean into a web service using 'servicegen' task and created corresponding client jar using 'clientgen' task. After that I can access that bean method(only one method which accepts List object as parameter) by using URI.
Here I got the problem. When I give the URI I got the method name and I clicked on it, it asks the input for the List object.
I give the data as
<list xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"

when click on Invoke button I got exception like Failed to invoke service:

Help:Invoke web service after receiving a user task response

Hi, All:
We encountered a problem while developing user task. The detail is as follows:
We need to invoke a web service after a user task's response, that is to say, the web service needs some data from the response of the user task.
Take the loan flow tuturial as a example, what we need to do is to invoke a web service after the BPEL process get the start loan APR. the web service needs the APR for its input message. how can I handle this situation?
Thank you very much for your help!

Thanks for your immediate response Jan Vervecken.
I have created the Data Control from web Service proxy and I am able to recieve the output from the web Service.
But, Currently I am invoking the webservice process method by a command button which populates my SelectOneChoice.
My requirement is to invoke the web service 'process' method by value change event in the SelectOnechoice control.
So, Can you pls. let me know how do I bind the web Service method 'process' to value change event of SelectOnechoice control?
Thanks and Regards,

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.

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.

Hi Rich,
i have built one application i.e. one program in ABAP, which has some 10-15 Dialog Screens in it, but the requirement is to call that program from an external Website , i am totally dumbstruck, and have no clue on how to do it, my last Query was answered by you, so i am directly adressing you, as u said, we can handle this kind of situations with Web services. Please explain me in detail, if its possible with an example.

Hi,
SAP has a number of different ways that data can be presented to or obtained from a web page.
- If the web page is to be built using external tools that just want to call SAP as an interface, then the Web Service is probably the best choice. This requires you to build the business logic independant of the screen logic as described by Rich.
- If SAP is to produce the Web page, then tools such as BSP, Web Dynpro and ITS can be used. BSP gives the best presentation at a cost of having to code to handle some browser peculiarities. Web Dynpro gives slightly less flexible presentation, but is more stable in handling supported browsers and is SAP's preferred way forward for web presentation within a company. ITS is older technology and requires more HTML and Javascript coding, but can provide a simple front end for Dynpro based screens (eventually these will need to be migrated to BSP / Web Dynpro as SAP reduces support for ITS - they are already moving most internal services, and have made documentation on the ITS almost impossible to find in SAP Help).

Need help developing web services on Jdeveloper

Hi,
I'm having some problems developing a particular web service using jdeveloper 10.1.2.1.0 (build 1913).
The web service is located on a remote computer (windows server 2003 SP1), deployed on a jboss3.2.5.
I got the following error:
java.lang.ClassCastException: oracle.xml.parser.v2.XMLText
at oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub.fromElement(WrappedDocLiteralStub.java:614)
at mypackage1.PdfGenStub.getConfigurationXML(PdfGenStub.java:189)
at mypackage1.PdfGenStub.convertDocumentToPdf(PdfGenStub.java:241)
at mypackage1.PdfGenStub.main(PdfGenStub.java:42)
The web service is from a product that we have that converts documents to pdf.
Any ideas ??
However, I will try to intall the product on another machine that has connection outside the company network to put the WSDL link here for anyone who wants to test it .
thanks

Hi,
Would really help if you could provide the wsdl and also steps to reproduce this exception, for us to try it out locally.
You could also try to install the latest JDev 10.1.3.1 available on OTN, to see if it works on it.

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.

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

Please help with web services (JSR 172)

Hello!
I'm in need of some help. I've only worked with web services some few weeks. I have two web services that I want to access from J2ME.
Both works nice in regular Java (J2SE). I use axis so with the help of WSDL2Java I got a working client.
One of them has four operations
    public boolean tryToLoginUser( String username, String password ) {}
    public boolean tryToLogOffUser( String username, String password ){}
    public boolean createUserAccount( String username, String password ){ }
    public boolean removeUserAccount( String username, String password ){ } The problem is when I want to use Sun's Wireless Toolkit 2.2 and create stubs that way with the Stub Generator. It complains with this
warning: Operation tryToLoginUser is of the wrong encoding SOAP style/use (rpc/encoded). Document/literal only. Skipping generation of operation.
warning: Operation tryToLogOffUser is of the wrong encoding SOAP style/use (rpc/encoded). Document/literal only. Skipping generation of operation.
warning: Operation createUserAccount is of the wrong encoding SOAP style/use (rpc/encoded). Document/literal only. Skipping generation of operation.
warning: Operation removeUserAccount is of the wrong encoding SOAP style/use (rpc/encoded). Document/literal only. Skipping generation of operation.What I can tell is I need to put this in my axis deployment descriptor
<service name="UserWebService" provider="java:RPC" style="document" use="literal">instead of this:
<service name="UserWebService" provider="java:RPC">This wont work. It don't work with HTTP GET I get this error

warning: Port "UserWebService" does not contain any usable operationsDoes this mean I can only use one parameter for input in an operation when I use style="document" use="literal" ??
I understood it that way, so I created a new web service that takes username and password in one String.
The new web service has four operations
    public boolean tryToLoginUser( String usernameAndPassword ) {}
    public boolean tryToLogOffUser( String usernameAndPassword ){}
    public boolean createUserAccount( String usernameAndPassword ){ }
    public boolean removeUserAccount( String usernameAndPassword ){ }The problem is that I get this error when running HTTP GET.

</soapenv:Envelope>If I get a WSDL2Java client it works (!) if I manually changes the parameter names. I have four operations which all takes
String usernameAndPassword
in one String since I can only use one parameter with style="document" use="literal"
The WSDL2Java automatically set the parameter names to
usernameAndPassword
usernameAndPassword1
usernameAndPassword2
usernameAndPassword3
for the different operations. If I manually changes them to all have the name
usernameAndPassword
it works. Why doesn�t it work without manual changes? I haven�t tested the code from Sun�s Wireless Toolkit 2.2 Stub Generator yet, but that at least doesn�t give any errors .
My other web service doesn�t work either if I set style="document" use="literal".
This web service returns my own classes I have written. It works as I said previously in J2SE with WSDL2Java, but not with style="document" use="literal�. When I set this my byte[] which is returned is null when using the client from WSDL2Java, this wasn�t the case without style="document" use="literal�.
I also get an error in Sun�s Wireless Toolkit 2.2 that byte[] is not recoigniced. This wasn�t the case with axis WSDL2Java.

So my questions are:
Do I really need style=�document� use=�literal� for J2ME?
Can I only have one parameter as input when I use style=�document� use=�literal� ?
Why do I need to manally change the parameter names?
How can I make Sun�s Wireless Toolkit 2.2 understand byte[] ?
Many thanks for help :) (I have to present a solution in 1 � week to my J2ME teacher L).

hi,
i was wandering if you manage to successfully generate the stubs through the wireless toolkit at the end? i am currently having similar problem (i.e., trying to generate stub files based on wsdl from axis)? it seems that the WTK can only handle document/literal format, and so i change the wsdl to that. however, now it complains that it can't handle more than one input part in the message, (which is similar to the problem you had). so did you manage to find a solution to that, or J2ME simply does not support more than one arguement as the input?
thanks in advance,
lee

Regarding Web services security.

Can I implement a database level username/password security for a web service.
So only database users can access the web service.is it possible?
Any implementation example or related document?
Thanks!

Hi Soni,
Yes, you could.
Two options I can think of:
- Program WS-Security for your specific web service
- Use Oracle Web Services Manager
With respect to the latter: I believe there is no OWSM policy step to handle your requirement out of the box. OWSM comes with policy steps for file-based authentication as well as for authenticating against Active Directory or a generic LDAP directory.
In this case you could opt for the creation of a custom policy step.
Hope this help.
