Web services Context

Hi,
I need to use a shared context to hold the application session across various web service invocations. I found WS-CTX (http://docs.oasis-open.org/ws-caf/ws-context/v1.0/wsctx.html) supports that. But I am not sure of how to implement it.
Can anyone help with me the details? (with sample code plz :))
Does Axis supports WS-CTX?
Thanks
Ajay

no.
we don't expose ServletContext for now

BAPI Web Service Context Mapping Problem

Hello all,
I am developing a process consisting of an automated activity.
This automated activity uses a logical destination for a web service call to an ECC BAPI.
The BAPI name is 'BAPI_INQUIRY_CREATEFROMDATA2'
Now the problem is the Output mapping in the automated activity which calls the web service for the above BAPI has the response name as 'BAPI_INQUIRY_CREATEFROMDATA2.Response'
So when i try to map the nodes it gives me an error, 'Error at Line 2, Column 29, Found '.' after BAPI_INQUIRY_CREATEFROMDATA2'.
Since there is no mapping i do not get the process working
If i remove the '.' from the wsdl file source, mapping is done. But the backend service call gives an error.
How can i solve this problem?
Any inputs will be very helpful.

Hello Martin,
thnks a ton for your replies.
The '.' is a standard thing.
Its the part of the WSDL file which is a standard WSDL file for a service offered for a standard SAP BAPI. So i haven't changed anything.
Its what is standardly available. So i cant anything on that.
And the response element is not below the bapi node.
The name of the root node of the BAPI return context is
"BAPI_INQUIRY_CREATEFROMDATA2.Response"
This is what is causing the problem.
Please note here that '.' is not responsible for any hierarchy. Its the name of one single root node element.

Create, get and update web service context mapping

Hello,
I think I have a pretty common problem. I will explain it with a simple example:
I have a car object, with the attributes id, name and speed.
I have three web services: create, get and update
I have a view with the input fields id, name and speed
How to do the context mapping?
When creating a car it would be good if input fields would be mapped to the create service, when getting a car it would be nice if the input fields would be mapped to the get service....
How to deal with this situation? Do I have to create 3 views?
Thanks!
Felix

Stateless Bean - Web Service Context

Is there anyway to specify the root context of a stateless bean that is also annotated as a webservice
Example
@Stateless
@Local(**)
@LocalHome(**)
@WebService(**)
@WLHttpTransports(contextPath="rootPath", serviceUri="uri")
Normally i would expect this to be accessible through http://host:port/rootPath/uri?WSDL
This format does work without the session bean if ran through Weblogics Generators, but is it possible to do the same thing with a bean? Or if it's not possible using WLHttpTransports what would the other method be?
Thank you

user8008029,
The WLS JAX-WS stack does not support all of the proprietary annotations from the JAX-RPC stack. This annotation (@WLHttpTransports) is one example. However, you can still override the context and service mapping using descriptors.
The descriptor is [weblogic-webservices.xml|http://e-docs.bea.com/wls/docs103/webserv_ref/dd.html] ...
Here is a sample:
<?xml version='1.0' encoding='UTF-8'?>
<weblogic-webservices xmlns="http://xmlns.oracle.com/weblogic/weblogic-webservices" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-webservices http://xmlns.oracle.com/weblogic/weblogic-webservices/1.0/weblogic-webservices.xsd">
<webservice-description>
<webservice-description-name>YourEJBService</webservice-description-name>
<webservice-type>JAXWS</webservice-type>
<port-component>
<port-component-name>YourPort</port-component-name>
<service-endpoint-address>
<webservice-contextpath>rootPath</webservice-contextpath>
<webservice-serviceuri>/uri</webservice-serviceuri>
</service-endpoint-address>
</port-component>
</webservice-description>
</weblogic-webservices>
Note: you may use the <WLHTTPTransport/> element with the [ jwsc ant task|http://e-docs.bea.com/wls/docs103/webserv_ref/anttasks.html#wp1069899] . This will build your service and automatically create the appropriate descriptors.

Using the UWL API inside a Web Service

I wrote a Web Service to get the number of new tasks and the total number of tasks for a user like it is displayed in the UWL in the DefaultView.
The numbers are retrieved by the following code:
user = com.sap.security.api.UMFactory.getAuthenticator().getLoggedInUser();
// JNDI lookup for getting the service because we are not in the PRT container
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sapportals.portal.prt.registry.PortalRegistryFactory");
InitialContext initialContext = new InitialContext(env);
uwlService = (IUWLService) initialContext.lookup("/broker/services/" + IUWLService.ALIAS_KEY);
if (uwlService == null) {
     throw new Exception("Cannot get UWL Service");
context = new UWLContext();
if (user == null) {
     throw new Exception("No user");
context.setUser(user);
context.setLocale(user.getLocale());
session = uwlService.beginSession(context, 200);
context.setSession(session);
context.setAllowBackEndConnections(true);
itemManager = uwlService.getItemManager(context);
UWLView view = uwlService.getViewManager(context).getView("DefaultView", context);
if (view != null) {
     QueryProperties properties = new QueryProperties();
     properties.setMaxNumberOfItemsToFetch(0);
     QueryResult result = itemManager.getItemsForView(context, view, properties, null);
     totals = itemManager.getTotalAndEmphasizedItemCountForView(context, view, "", null);
In the first step I chose basic authentication. When debugging I see that the web service gets the information about the logged on user. The UWLService, item manager, session and view, all of them are determined resp. created.
But when calling getItems the UWL exception "Logged in users context or session doesn't exist" is thrown.
When calling the same functionality from Web Dynpro everything works fine.
Service and session are determined like this
uwlService = (IUWLService) WDPortalUtils.getServiceReference(IUWLService.ALIAS_KEY);
context = new UWLContext();
IUser user = WDClientUser.getLoggedInClientUser().getSAPUser();
wdContext.currentUIStateElement().setUserName(user.getFirstName() + " " + user.getLastName());
context.setUser(user);
context.setLocale(WDResourceHandler.getCurrentSessionLocale());
session = uwlService.getUwlSessionForWebDynproClient(context);
Does anyone know how to work with the UWL API in a web service context?
Thanks in advance
Antje

Hi Experts,
We are also facing the same issue as of Yomesh.
The strange part here is that, yesterday, the code was fetching the User and we were able to run the whole web service.
Suddenly, this doesnt seems to be working today. And after debugging, we found that, the User is not being returned with the below code:
user = UMFactory.getAuthenticator().getLoggedInUser(wsContext.getHttpServletRequest(), null);
Any help is highly appreciated.
Thanks in Advance!!

How do we deploy several Web Services under the same Root Context?

We have several webservices, each in their own WAR file, running on OC4J 10.1.3. They each have their own Root Context and Oracle Welcome Servlet. This works well, and since they are all separate we can easily hot-deploy updated versions.
The drawback is separate URL's like :
.../RootContext1/WebService1
.../RootContext2/WebService2
.../RootContext3/WebService3
How do we assemble our Web Services to share a single Root Context? We are hoping to achieve URL's like this :
.../WebServices/WebService1
.../WebServices/WebService2
.../WebServices/WebService3
Do we have to bundle them all into the same WAR/EAR (and loose the power of individual deployment) or is there another way?
Thanks in advance!

If each one is a separate WAR file, then at the OC4J level each one will need a separate root context as it gets bound into the default-web-app.
I guess the corollary question here is if there is someway to combine multiple webservice endpoints into one WAR file -- which can then be mapped to a single root context.
I'll try and get someone more WS savvy than myself to take a look at this for you.
And Clever Apache is a viable option.

Sending controller context value attributes to web service model

Hi,
I have put some parameters (value Attributes) in controller context and mapped to different views. Is there any way by which i can send the values to the web service model , each time the web service is called? like through header or some thing like that??

Hi Sujesh,
Read those value attributes in your controller using following code:
wdcontext.currentContextElement().get<attribute>();
and then set these value in your web service model.
<model name> model = new <model name>();
model.set<attribute>(<value>);
wdcontext.node<nodename of your web service model>().bind(model);
wdcontext.current<nodename of your web service model>element().modelobject().execute();

Bhavik

(SJAS9) Reading a context param in a web service

Platform - SJAS9, NB5.5
I am trying to add a web service to a small web project and I need database access for it.
My web.xml defines 2 different resource-refs for my databases, jdbc/development and jdbc/production. There is also a global context-param named database with values of development or production that defines which database the web app should be using.
I have two database pools set up under SJAS9 for these resource names, and the servlets can access these just fine using :
    protected Connection getConnection() {
        Connection conn = null;
        try {
            String datasourceName = "jdbc/" + getServletContext().getInitParameter("database");
            Context initCtx = new InitialContext();
            Context envCtx = (Context)initCtx.lookup("java:comp/env");
            DataSource ds = (DataSource)envCtx.lookup(datasourceName);
            log.debug("retrieving database connection for " + datasourceName);
            conn = ds.getConnection();
            log.debug("done");
            conn.setAutoCommit(false);
            return conn;
        catch (SQLException ex) {
            log.error("error getting a connection", ex);
            return null;
        catch (NamingException ex) {
            log.error("error finding the datasource", ex);
            return null;
    }I have just added a web service to the project, and I can't find a way to get the context param. When I created the web service, Netbeans added some annotation around it, and it is not extended any class or implementing any interface (that I can see).
For the web service, there is no appropriate method equivalent for the call
            String datasourceName = "jdbc/" + getServletContext().getInitParameter("database");so how do I retrieve the context param database so I can know which resource pool to obtain the connection from inside the web service?
Thanks
Chris

Here's how to invoke getServletContext() from a web service:
First you'll need to add "ServiceLifecycle" to the list of implmentations of your class:
public class MyService implements WebServices.MyServiceSoap, Remote, ServiceLifecycle {}Next you'll need to add the following:
private ServletContext servletContext;
public void destroy(){}
public void init(Object context) throws javax.xml.rpc.ServiceException {
   ServletEndpointContext soapContext = (ServletEndpointContext) context;
   servletContext = soapContext.getServletContext();
Hope this helps!

IRM Web Services Adding a New Role to a Context

We are in the process of using the IRM web services to create a system that will automatically create users/contexts and seal documents over the web.
So far I can successfully create users and groups and assign permissions properly as well as create context.
I am having trouble adding roles to the context.
The error I'm getting is "The attribute 'Features' is mandatory".
The problem is that there is no function to add features to the ContextRole object.
How do I set up the features so that I can save then new ContextRole?
Tom

Hi Tom
Response from engineering on your latest questions:
Depending on which web service code generator is used, collection typed properties may or may not be provided with set operation. If the code generator does provide a set method for collections, then you can just specify the set of features you require as so:
// Java
Collection<Feature> features = new ArrayList<Feature>();
features.add(feature);
ContextRole role = new ContextRole();
role.setFeatures(features);
However if the set method is NOT provided, then you need to manipulate the collection directly, by using the get method and then using the standard collection methods to alter the contents.
// Java
ContextRole role = new ContextRole();
role.getFeatures().add(feature);
These two examples are functionally the same, they both create a context role object with one feature.
Kind regards
Andrew

About context-root setting method of Web service

When you generate Web service, please teach me the context-root setting method.
With JDev9.0.5, Although it sets in webservices.xml.
With JDev10.1.3, There is no context-root element
Environment:

Hi,
can you please describe, how you build this asynchronous HelloWorld service?
With Jdeveloper 10g building asynchronous java webservices is not supported.
So how did you build this asynchronous webservice?
If this HelloWorld service is a bpel project, then the invocation from another BPEL via invoke and receive should work...

@common:context annotation on web service problem

Is there a problem with using the @common:context annotation for a conversaitonal web service, such that session information isn't maintain?
My problem is that when i authenticate from a jsp or programmatically, i have session info. I continue to have this info prior to calling the conv. ws, but after that, from the conv. ws and any control, JPD, etc... that i use the session info is lost. This is a problem for me because i want to use role security and the anonymous user always is used at the point of the ws and on.
Is there anyway around this, is this a bug, or am i just using this incorrectly?

I am having the same issue. The one thing I did notice when I compared the output from the sample and my app is the following;
RESPONSE;
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<state xsi:type="xsd:string">OH</state>
</return>
</ns1:getCityStateResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The major difference seems to be that the string 'urn:usps-' has been added to
xmlns:ns1="CityStateLookup"
making it
xmlns:ns1="urn:usps-CityStateLookup"
I built mine thru the wizards, trying to replace the compute the values prior to automatic row-processing, as well as calling the web service after retrieving ZIP from the database and computing city and state. In every case, I get a successfull call but a blank response value and no city and state.
Any help would be appreciated.

Web services and servlets in same context

I would like to provide web services and servlets under the same context, where the servlets are handled by a controller mapped to multiple urls.
If I map the servlet controller with
<url-pattern>/servlet</url-pattern>
then /prjServ/servlet works in a browser but of course any other urls (eg /prjServ/servlet/fred) do not.
If I change the web.xml to be
<url-pattern>/servlet/*</url-pattern>
all attempts to access the servlet get requested resource not available.
The web service continues to work fine whichever mapping I use for the servlet (the web service is /prjServ/mlm).
Does the web service handling affect the way I can map the servlets?

No, it should not. For the JAXRPC SI, the web services are implemented
via one common servler.

Getting servlet context in a web service

Hi,
I have a problem but have no solution to it and am not sure of the approach.
I am creating a web service. Some parameters will be passed to this web service. I need to capture these parameters and put it in a hash table so that it is available to another applicatins servlet context i.e.
there will be two calls .
first the web service is invoked and the parameter is stored in the hash table of the applications servlet context.
Next when the application is invoked it shud refer to the hash table and get the data in the hash table that was stored by the web service and process it.
How can this be achieved?

Well, some experts will wanna kill me for told that, but, lets go....
Comparing with the JVM, a context is like a class path (of course they have many differences). In other worlds the context is a directory (or war file) where the web server (for example TOMCAT) wiil search your .class files (or.war, .jar, etc...)
All context are "pointed" to a dir, for example you can point the context /myapps to a dir of your OS (for example /home/your_username or in a windows system - C:\Program Files.
Then when you acces this context at the browser, the browser will show this directory hierarchy. For you execute your servlet you need to create a WSDL (the descritor file). This file is nothing more than a XML document (that had rules) and link a servlet at a context, (for example the servlet Hello can pointed to the path /hello, and then, this servlet is "install" at the context /myapps). After this, you can access your servlet at the path http://computer_address/myapps/hello.
Note: Step by step, you need:
1) create the web application strucuture directory (the WEB-INF, classes, etc...)
2) write the servlet
3) write the web.xml
4) compile the servlet
5) create a context - point the context to the web app structure "father"
6) install this servlet at the context
7) access the servlet
I hope this help you to understand some things, but for learning I recomended the Tomcat manual!!!! Good Luck.

Web Services - UDDI Context Menu

Hi
I have been following the documentation on the creation of a web service and all was well until I wanted to pubish it. The documentation tells me to right click on the UDDI icon in the variants tab of the Virtual Interface and select publish.
However, I do not get a context menu appear.
Any ideas anyone? I'm on ECC6.
Cheers
Ian

Hi,
you may want to try the wsdl4j api, provided by ibm. You can download it from ibm's site. This api provides the tools you need to get everything out of a wsdl file, like methods, in-parameters, out-parameters etc. Now, to completely create the remote call at runtime, you need to create the request and response datatypes at runtime, in case they are not primitive (could be java beans for example). If you know the way to do this, please make a post because this is as far as i have gone implementing a trully dynamic client. i don't know how to create and use new classes at runtime.
i hope i gave you some help
