Multiple web services sharing same session?

I was wondering if anyone has ever implemented multiple web services for an application that allowed the web services to share the same session?
Furthermore, I was wondering if support might be included/buried in the WSDL spec. somewhere?

There are a number of standards emerging to support long-running conversations among Web services as well as Web service composition. Can you expand on what you're trying to achieve?

Multiple web apps sharing same cache in a single JVM ?

Is it possible to share cache across multiple web apps running in the same app server (multiple web apps, single JVM) ?
Thanks for any info.

Hi Bob,
Cluster membership is scoped to the ClassLoader, so if your application server provides a ClassLoader-per-application, this will work fine.
This is supported for both Coherence (NamedCaches) and Coherence*Web (HTTP sessions).

Multiple Web Services in one Jdeveloper project

Hi all,
I'm currently trying to implement a series of web services, all relating to one application. I'm using the top-down approach, where I generate the web service from a WSDL file, and add my implementation to the generated classes. The WSDL file imports all sorts of XML Schemas (xsd-files) and Jdeveloper correctly generates all the necessary java-classes for me. Lets call the first web service I create WS-1.
This all works fine and I'm a happy panda. I can call the web service, it works, I can modif the wsdl and regenerate the web service to e.g. change the input etc. All this works.
Just until the point where I want to create a second web service (lets call this WS-2). This new web service doesn't use all the XML Schemas that the first web service does, it is more simple with regards to in-/output. The problem arises when I modify WS-2 and Jdeveloper regenerates the Web service files (.java and the files in the WEB-INF/wsdl-directory). When I do this, it deletes the imported xsd-files that WS-1 uses (removes them from WEB-INF/wsdl).
And when I regenerate WS-1 to get my xsd-files in again, then when I regenerate WS-2 it imports all the unnecessary xsd-files into the wsdl for WS-2.
Something tells me, that there is a connection or shared library between all web services in one Jdeveloper project. That they all imports and uses the xsd-files in WEB-INF/wsdl.
Is this true? Can't I have multiple web services (and wsdl-files) using different types (schema definitions) in the the same Jdeveloper project?
One solution I can think of, is to have all my web services in different projects under the same application. But is this really necessary?
I'm using Jdeveloper 10.1.3.3.0.

Hi,
pure from a coder instinct I think I would prefer them to be in separate projects for better reuse and clean separation. If I need project 1 to access aclass from Project 2, I can check the dependency check box in the project properties. Is there any business requirement that makes you think having all of these in a single project will help ?

Btw.: I agree that JDeveloper shouldn't constraint developers from doing what they want and if this is a limitation the feel free to file a bug

Does any one have insights about it?

Hi Swapna,
from your screenshot it seems that you actually try to call the service in your Data Source Expression field. You should set path to the WSDL file here actually - this could be either URL to SAP or to filesystem, as Anton suggested (this could be faster). Have you created endpoint binding for your service in transaction SOAMANAGER? If yes, then simply download the corresponding WSDL with binding or copy the URL which leads to it. But also test whether you are able to retrieve the WSDL without logging into SAP (close all browser windows and then open a new one otherwise session ID from other browser windows can be reused).
If you have to give username and password, then setup anonymous alias in transaction SICF, for example.
Pleas, check my previous post on the same subject here: Re: BCM7 IVR : SOAP request for client identification in CRM .
Maybe it could help.

Dawood.

OWSM and Webservices -Define policies once for multiple web services

I thought that through using OWSM we had the possibility to use the same Policy Lines for multiple web services.
Mostly when web services are used/integrated within an application, the same rules need to be defined and I thought this requirement could be met when using OWSM.
But you need to define the policy requirements on each web service that's passing through a gateway or agent, why isn't it supported to define policy lines one level higher to be able to use the same requirements for multiple web services?

Nathalie,
For this purpose OWSM allows you to use Template Policy Pipelines.
For individual services, you can than replace the pipeline with the Template.
But I have to agree with you here: the templating functions are rough on the edges, e.g. limited editing capabilities.
Hope this helps.
Best regards, Sjoerd

Certificate error while connecting to multiple web service

I am having a web service test client through which I can connects and get reports from multiple web services.
In Development unix box, we are using "self-signed certificate" using keystore type JKS. In Production server, we are using certificate from CA.
The web service is running in Development and in Production.
Now I have developed single test client with a drop down selection for different web services. For example, if we select "Development", the request will go the development web service and if we select "Production", the request will go to Production web service.
Now while connecting to Develpment service, we are settings the below certificates details Because we are using the self signed certificate.
System.setProperty("javax.net.ssl.keyStore",keyStoreFileLocation);
System.setProperty("javax.net.ssl.keyStorePassword",keyStorePassword);
System.setProperty("javax.net.ssl.keyStoreType", keyStoreType);
System.setProperty("javax.net.ssl.trustStoreType",trustStoreType);
System.setProperty("javax.net.ssl.trustStore",trustStoreFileLocation);
System.setProperty("javax.net.ssl.trustStorePassword",trustStorePassword);
I am clearing the System properties using the System.clearProperty() while pointing to Production service. because in Production we are using the CA certificate from Thawte so these details are not required at all and our JRE (java 5) is pre configured to support that CA certificate.
I am using Resin-2.1.12, axis1.2 and java5.
Now the problem is
(1) for the first time, when I send the request to Production Service URL, the report gets generated. For the next time when we are running against Development, it's giving below certificate error.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
(2) Now restart resin and run the test client against Developemnt service URL, here report gets generated and for the next time, run the test client against Production, it's giving the certificate error.
So for the 2nd request, it always gives the error irrespective of the web service instance selected.
Please suggest ....thanks in advance.

Hi ,
No, due to the issue is happening only on one computer.
The error "(401) Unauthorized" usually indicates that the connection has been established but the permission check fails. InfoPath Form Services uses the application pool identity of the web
application to connect to resources.
Does the account which login the computer have permission to connect to User Profile Service Application?
For a workaround, you can go to IIS Manager , set the User Profile Application Pool to Anonymous Access and try again.
Also you can have a look at the blog:

Web Service from stateful Session Bean deleted after server restart

Hi,
i created a stateful session bean and from this a web service.
I am able to deploy it and it works really fine.
My problem is: after a server restart the web service is gone and i
have to deploy it again.
I have some other web services (but these are web services from stateless session beans)
but they "survive" the server restart.
I don't want to deploy the web service after every server restart, did I forget something or
is it a general problem of stateful session beans or web services?
Thanks in advance
Jens

Regarding multiple web service

Hi,
I am working on web services in EJB.
for securing the web service, we use jboss-wsse security.
Can i have multiple web services with few web services being secured and the others in-secured?
Thanks in advance.

Friends,
Can you please help me out with this logic? Thanks!

Can't have multiple Web Service connections in SP1

Hello,
I'm currently interested in adding more than 1 Web Service connection to a particular xcelsius file, but after adding the first connection, the option is disabled in the Data Manager screen. Is there a workaround for this, since before service pack 1 you could have any amount of connections and as off upgrading this was changed.
Regards

Yeah I totally agree, It's like someone giving you a bunch of new appliances for your home but then telling you that your not going to have any electricity. This product is pretty much usless to me now.
Just the thought of having to partially develop in one version of xcelsius and then port over to a version that has SP1 installed makes me ill. From what I can tell Xcelsius Engage Server still has multiple web service connection functionality enabled (http://www.businessobjects.com/product/catalog/xcelsius_engage/comparison.asp), I'm interested to see what the cost will be to upgrade to Server.

Is it possible to define multiple web services in one project?

I'd like to publish multiple components within one project as web services. but when I try to create it using the project New menu, it only prompts me and allows me to select one component . So does this mean only one web service can exist in one project?

Sunil
Thanks for the prompt reply.
I think I should have worded my question more clearly.
I have a project with multiple Java classes. I'd like to convert two of them into web services.
There are two ways to co this.
1. I right click on each class and select the Generate J2EE Web Service option. This will work correctly and allow multiple web services to be generated.
but this is not what I want to do .
What we are trying to do is to generate web services at the project level. I am following instructions in OTN web services tutorial :
http://www.oracle.com/technology/obe/obe1013jdev/ws/wsandascontrol.htm
So , this is what I do :
1. Right-click on my project and select New from the context menu.
2. In the New Gallery, expand Business Tier in the Categories list and select Web Services, then select Java Web Service from the Items list. Click OK.
3. In the Select J2EE Web Service Version dialog, select J2EE 1.4 (JAX-RPC) Web Service, then click OK.
4. Click past the welcome page
5. This brings me to the page where I can select the web service and class.
This is where I am stuck - it seems I can only select one web service here . Unless I am missing something.
Or should I just repeat the process multiple times - running the wizard once for each class ?
Thanks for the help.

Combine multiple web services with the same SQL query into one

Hello,
I would like to ask a question regarding combine multiple similar web services into one. Can you please tell me if it is possible to combine 4-5 web services into one since they built on the same SQL query with 5 different criterias or condition so that the user can enter any of the 5 criterias to populate the data on the form instead of having 5 different web services?
e.g Query: Select appName, permit#, address, phone, description, type, section, from table where appName = can be 'appName, permit#, address, phone, or description' to populate the rest of the data to the form.
Does any one have ever done some thing like this in Workbench ES? If so please assist. I know it can be easier to build it in Visual Basic, C#, or dot.net but the requirement is to build it in workbench ES.
Thanks in advance,
Han Dao

If you are querying for Name, PhoneNumber, and SSN, and you queried for all people with a phone number that started with 867, you would have a potentially long list of people. So to keep track of all of the people, we store each record in XML complex elements. The root node is just any name you want, and the repeating element is the complex element name.
So using the example from above, I'm going to specify the following:
     Root Node: Result
     Repeating Element: Person
So now when I do a query, my resultXML will look like:
<Result>
      <Person>
             <Name>Alex</Name>
             <PhoneNumber>867-5309</PhoneNumber>
             <SSN>111-11-1111</SSN>
      </Person>
</Result>
If your query returned multiple results (like ours would probably), it would look like:
<Result>
      <Person>
             <Name>Alex</Name>
             <PhoneNumber>867-5309</PhoneNumber>
             <SSN>111-11-1111</SSN>
      </Person>
      <Person>
             <Name>Han</Name>
             <PhoneNumber>867-2169</PhoneNumber>
             <SSN>222-22-2222</SSN>
      </Person>
</Result>
So Result and Person is just to give a little bit of structure to the xml result (containers really). So you can name them whatever is helpful for you.
The column name mappings map the query columns (Name, PhoneNumber, SSN) to some node in the XML (Name, PhoneNumber, SSN). So you don't need to specify which field maps to what in the form. Just copy the column names to the element name so you have a 1-to-1 naming. If you want to manipulate the XML a bit though, you could do:
Column Name               Element
Name                            YourName
PhoneNumber                Phone
SSN                              Secret
which would then make your xml look like:
<Result>
      <Person>
             <YourName>Alex</YourName>
             <Phone>867-5309</Phone>
             <Secret>111-11-1111</Secret>
      </Person>
</Result>
It lets you change the XML element names to whatever you want. Otherwise by default they take on their column names.
In your form, you could bind to the WSDL through the Data Connections pane and point it to your web service. This will then create form elements that you can just drag and drop allowing you to have the information available when the service gets ran. Once the service is called, you can modify the field's data to get whatever information you need in order to populate other form fields.
If that is too confusing, feel free to send me your form (e-mail is on profile page) and I'll add comments to it to show you how to set up the form for the web service call (and also give me the link to your webservice)

Multiple users to share same session

Hi guys. I am writing a Flash game, where the state of the game and the moves will be stored in the session. Several users will be sharing the same game session though.
Flash will send variables containing the move made by a particular player to a Servlet, that will be on a different web server. That Servlet will then return to Flash, when requested an XML response containing the state of the game for the next player.
Lets say there are always 3 players playing per game. How do I share this same session among those 3 users?
Question 1:
Is there a way to store a Vector of sessions in a Servlet?
Question 2:
Supposed the above answer is yes, I could send back and forth an id for the session between Flash and the Servlet. Is it possible to associate a session stored with a particular id? And how would I retrieve that session based on a given id?

Do you want to run multiple games concurrently? If so, the application object won't work, because all the user data will then be available to all users.
I would recommend that you continue to use the session-per-user paradigm. Instead of storing all the game data in session, store it in a global lookup structure (a Singleton or static variable of the servlet, probably a Hashtable). Key the game data for each user off of a unique id (potentially the session id?). In each user session, store the id's of the other users they are playing against.
So, when you are responding to a request from one user, you can quickly get the id's for the other players, use those to lookup the necessary game data for those users, and then use it to create your response.
At that point, all you need is some way to expire the data from your storage structure. If you store a "last access" timestamp along with the game data, you can use a thread to expire old data in much the same way that a session would be expired.

Implementing Web Service with Stateless Session Bean

I have a web service that I've built using the WorkSpace Studio tools (create a WSDL, generate the Java code from the WSDL, fill in the skeleton methods in the service implementation class). This service is deployed as a web module within an EAR to WebLogic Server 10.0 and is working great as a web service.
I'd like to be able to also call the operations on this service via an EJB interface (from a different application on the same server). I followed the guidelines for adding EJB annotations to the web service implementation class (from [http://edocs.bea.com/wls/docs100/webserv/jws.html#wp215790]). I added the @Session annotation to the class, implemented javax.ejb.SessionBean, and added the ejbXXX() methods. This all makes perfect sense, and looked like it was going to work. However, WorkSpace Studio now gives me a compile error on the class that says "EJB backed WebServices are not supported."
A few internet searches for that error didn't return anything relevant.
It seems like I followed the instructions correctly. Is there a better way to build a service like this that is both a web service endpoint and a stateless session bean?
Thanks!
-Eric

Having separate EJB and web modules certainly makes things easier, but I have non-trivial (i.e. not feasible to copy) application logic that I'd like to expose with both a bean interface (for intra-application usage) and a web service interface (for public consumption).
I've tried starting with a "web application" WorkSpace Studio project and adding bean annotations. This produces the error I originally described. I also tried starting with an "EJB" WorkSpace Studio project and adding web service annotations. This fails at deployment time with errors about missing web service descriptors (the error is correct - the web-service-related descriptor elements are missing from the deployment descriptors).
The documentation explicitly presents this as an option (annotating a class with both web service and session bean annotations), but how does one actually make this work?

Simulate Multiple users connecting to same session

Hi All,
Is there anyway we can simulate multiple users connecting to the same session in oracle using PL/SQL.
Thanks,
MK.

As per the architects in our company, lots of users connect to the same session and access the database.Exactly what does this mean? A single session can service one user at a time. I would wager that the architects are envisioning (or describing) a connection pooling setup where the middle tier server maintains a relatively small number of connections to the database (each with its own session most likely) and users operate by getting a connection from the pool, making a request, and returning the connection back to the pool. At any given point, only one user can be using a connection.
If that's the case, you would simulate this by simply executing code in a loop in PL/SQL.
Of course, if this is the case, each connection in the connection pool would its own copy of the collection and so each connection would get its own list of order numbers. You'd have to develop some way to ensure that each session populated its collection with a different set of order numbers.
