How can my web service class implement an interface

I am not able to write :
webserviceclass implements interface
I am using servicegen script to convert java file to the web service.But then also,if i add
javaClassComponents="javaclass1,interface1"
It is saying interface1 does not have any no arg constructor,so can't used in the web service.
kindly tell how can i code my web service to implement an interface.

That said... Firefox honors the setting autocomplete="off" in the form tag. When this attribute is set, users should not be prompted to save the username/password, and it should not be filled automatically. (Is this what wasn't working??)
https://developer.mozilla.org/en/How_to_Turn_Off_Form_Autocompletion
Knowledgeable users can bypass this setting by running a script to strip this attribute. I doubt that very many users would do that, but if people have to log in very frequently, it is more likely to happen. Users also may use add-ons that manage passwords, and those add-ons might not honor the autcomplete="off" setting. I haven't used any such add-ons, so I don't know the situation there.
I'm sure this isn't completely satisfactory but hopefully it helps to some extent.

How can a web service be compliant with the WTK2.1?

I'm using WTK2.1 to develop mobile clients consuming web services.
After published a web service by Apache Axis, I use WTK2.1's Stub Generator to
generate the stub class.
As required by JSR172, I use the "document/literal" encoding style.
The web service class has only one method:
public int newUser(String userName, String password) {
But when I use Stub Generator to generator the stub class, I get the following messages:
************************ Error messages begin *****************************
warning: R2716 WSI-BasicProfile ver. 1.0, namespace attribute not allowed in doc/lit for soapbind:body: "newUser"
warning: R2716 WSI-BasicProfile ver. 1.0, namespace attribute not allowed in doc/lit for soapbind:body: "newUser"
warning: ignoring operation "newUser": more than one part in input message
warning: Port "User" does not contain any usable operations
************************ Error messages end *****************************
And following is the wsdl file:
<?xml version="1.0" encoding="UTF-8"?>

<wsdl:port binding="impl:UserSoapBinding" name="User">
<wsdlsoap:address location="http://localhost:8080/web/services/User"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
So, can anybody tell me how to make the web service be used by the Stub Generator properly?

Hi,
I am new to WTK 2.1 and I am also using Axis to generate WSDL.
one thing I figured out was to remove the namespace info behind all body tags.
for instance in your code, replace:
<wsdlsoap:body namespace="http://localhost:8080/web/services/User" use="literal"/>
by
<wsdlsoap:body use="literal"/>
and it should work. don't ask me why but it worked for me.

(261680070) Q SYNCH-11 How do my web service methods accees EJBs and java classes?

A<SYNCH-11> How do my web service methods accees EJBs and java classes?
A<SYNCH-11> It is simple to use java classes, just do it as you would ordinarily.
The .jws file really contains a simple class so you can program with it in the same
way that you would use a regular Java class.
To use an EJB you can go and access it directly as you would with any EJB remote
client (lookup home stub, create, etc) or if the EJB is deployed to WLS you can use
a control to provide a very simple wrapper to the EJB. We will see this in detail
on Thursday in the ADVC module.

Futher information about the possibility of callback:
It may be possible for a synchronous only web service (i.e. MS .net) to even paticipant
in the callback functionality of asynchronous web services. If the client implements
the appropriate methods for the callback but listens for them on a different port
or binding than the SOAP request, then web service may be able to build a response
if the client's "callback URL" is submitted as the beginning part of a conversation.
Watch the BEA developer forum (http://dev2dev.bea.com) for more information about
this approach and other tips and techniques for building web services.

Q<SYNCH-03> I heard that MS .net only implements synchrnonus method? If
this is true.
Does it means my async methods will only work with J2EE clients?
A<SYNCH-03> I do not know the limitations of .net but let me point out that
is very
difficult to provide asynchronous web service method invocation (this is
different
from an asynchronous web service). HTTP as a general communication protocol
is based
on a request and response paradigm so your client libraries will mostly
likely be
expecting a response even if it is empty (check the asynchronous example
from today
to see that the start method still returns an empty response). You must
distinguish
this from the notion of an asynchronous web service which is a business
operation
that occurs on the server whose return value/result is not directly associated
with
building response to the client. An asynchronous web service can (and generally
will)
be started and stopped with web service operations that are invoked synchronously.
Thus MS .net clients can still be client to WLS hosted web services.

How to consume web service in Agentry in SMP 3.0

Dear All , I am using web service in Agentry to retrive data but could not able to fetch it . I have made connection with HTTP-XML for consuming webservices. and also give proper information in Agentry.ini files Ex : [HTTPXML-2] name=HTTP-XML Back End authenticationCertificateStore=MY authenticationCertificateStorePassword= authenticationCertificateStorePasswordEncoded=false autoDequote=true ;baseURL=http://localhost:81 baseURL=http://sapes1.sapdevcenter.com:8080/sap/opu/odata/iwbep/gwdemo/ basicAuthenticationPassword=123456 basicAuthenticationPasswordEncoded=false basicAuthenticationUserID=P1466405733 constantsFile=httpxml_sd.ini enableAuthentication=false enablePreviousUserAuthentication=false httpConnectTimeout=300 httpReceiveTimeout=300 httpResolveTimeout=300 httpSendTimeout=300 listenOn= timeout=300 timeZoneName= useSSL=false xmlAllowXSLTScript=true xmlNamespaces= xmlResolveExternals=true xmlValidateOnParse=true for more information i have attached agentry XML screen shot as well . Can you please guide me how to consume web services in Agentry correct way ? Note : Currently i am using standard netweaver demo web services . Thanks & Regards , Kunal Varaiya
Tags edited by: Michael Appleby

The XML Steps URL will be added to the Agentry.ini BaseURL. So you dont' need the full URL on the step.
So when Agentry Runs the step to call the backend it will go:
<BaseURL>/<Step's URL>
This way if you need to change the base URL, IE, going from Dev to QA to Production Server you only need to change the Base, and not go into every step and update it.
URL: This attribute contains the URL to which the Agentry Server will make a request. This value will be appended to the value configured as the base URL for the HTTP-XML system connection. This base URL is configured within the HTTP-XML system connection configuration options for the Agentry Server. Proper use of both this base URL option and the URL entered in the requests of the step definitions can support portability for the application, with the base URL being the implementation-specific portion and the step’s URL being the portion not likely to change for the same back end system from one implementation to the next.

How to deploy web service as part of console.war

Hello,
I need to expose the deploy functionality of bpel console as web service. I see that there is a JSP page which pretty much does the same thing in console.war. So I know what my Java class is going to look like the problem is I am very new to OC4J so I don't know how to deploy it as web service on this container. Any help is greatly appreciated.
I tried going through the tutorial on deploying web services on OC4J but the sample stateless class does not compile because it cannot find some proxy classes. Also next I copied ws_example.ear in 'D:\OraBPEL_1\bpel\system\appserver\oc4j\j2ee\home\applications' and restarted server but it is not deployed.
Thank you,
Meghana

Thank you for replying to my post.
The requirement is that we deploy BPEL suitcase remotely. My impression was that one can get handle to the Locator object only if running on local machine so I was looking at how to create web service on Oracle BPEL PM itself that will accept the stream of jar and deploy it locally.
However now looking at this tutorial and the Java docs, I know it supports RMI calls. So I can use this constructor to get Locator instance -
public Locator(java.lang.String domainId,
java.lang.String password,
java.util.Hashtable pInitialContextProperties)
throws ServerException
Can you let me know sample initial context properties? I checked the sample InvokingProcesses' context.properties
orabpel.platform=oc4j_10g
java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory
java.naming.provider.url=ormi://ca-guru/orabpel
java.naming.security.principal=default
java.naming.security.credentials=welcome1
My guess is I have to change that url but I don't know where to point it. Also could you please let me know what are the jars I will need on the client side?
Thank you. I appreciate your help.

How can i include Services and Bindung in a generated WSDL file?

Hi,
i what to use a generated wsdl file from an erp system, to build a web service client with WSDL2Java (org.apache.axis.wsdl.WSDL2Java).
I noticed, that services an bindings are missing, also a policy is included.
How can i include services and bindings in the wsdl and exclude the policy?
Thanks!

well, I assume you have SOAMANAGER.
choose your service & "Apply Selection" (very useless button btw)
select a binding in the dropdown box or create on if you do not have one yet
Click button "Show WSDL options" (actually they do not really look like buttons in WD; call it yellow blot)
Some extra config area is thrown onto your screen (without any sense for usability or design); Change the radio button for WSDL format from "WS policy" to "Standard"; make sure the first radio button group is on "True" for monolithic
Now click the link (why is this a link and no blot?) called "Display selected bindings WSDL URL"
an extra text field is again thrown onto your screen somwhere between the dropdown and the WSDL option config area containing an URL (get out your glasses if you don't see the sub-10pt-letters)
hope it helps,

How to update web service proxy in JDeveloper 10.1.3.0

hi all
I want to ask how to update web service proxy in JDeveloper 10.1.3.0?

What do you mean update?
You can go into the source code and update whatever you want.
If you mean that the WS spec has changed - then you can either change the proxy manually, or create another proxy.
