Web Service to do Java PDK .setProperty() and .store()

I had posted this in the EP Content Development group, but received no response. Sorry for the cross post but this is relatively urgent for me.
I am working on a Portal Component in the PDK for .NET which will take values selected from a CheckBoxGroup, concatenate it to a string and write that to a single Personalization preference.
However, the PDK for .NET does not support writing Personalization preferences to the PCD. Thus, I have determined the solution to be:
Make a Portal Service that takes a value and writes it to the Personalization of an iView. Basically it needs to simply do a:
IPortalComponentProfile profile =
request.getComponentContext().getProfile;
profile.setProperty("selectedVal", myData);
profile.store();
Then this will be converted to a Web Service. However, how will the Web Service know what iView its writing Personalization for?
I've searched and searched and come up with little clues here and there that I've somewhat pieced together but no concrete solutions. Please help. Thanks! --Shibli

Hi,
I took a look at the portal javadoc and there is another getComponentContext method that gets a string, urn, perhaps that will help.
Take a look <a href="https://media.sdn.sap.com/javadocs/NW04/SP12/runtime/com/sapportals/portal/prt/component/IPortalComponentRequest.html#getComponentContext(java.lang.String)">here.</a>

  • Any difference in creating a web service from a java class or session bean?

    Hi,
    The JDeveloper tutorial at http://www.oracle.com/technology/obe/obe1013jdev/10131/devdepandmanagingws/devdepandmanagingws.htm demonstrates creating a web service from a plain java class. I'm wondering:
    - Is it possible to create a web service from a stateless session bean instead of a java class? If so, what's the proper way to do this in JDeveloper? When I tried doing so in JDeveloper 10.1.3.0.4 (SU5) using the J2EE Web Service wizard, the wizard did not list the session bean in the Component To Publish dropdown (it does list any java classes available in the project). I can proceed by manually typing in the name of the session bean. After the wizard completes though, the @Stateless annotation that had been in my session bean class code is removed and replaced by a @WebService annotation. The end result is that it looks like it made no difference whether I had tried to create the web service from a session bean or plain java class as the annotations in the resulting web service code are the same (although if I had started from a session bean, the class for the web service still implements the Local/Remote EJB interface that the session bean originally implemented).
    - Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean? I'm creating the web service from scratch so I also need to either build the java class or stateless session bean the web service would be based on from scratch too.
    Thanks for any ideas about this.

    Hi,
    EJB Session beans (EJB 3.0) are deployed as WebServices by annotating the class with @WebService and the methds with @WebMethod (both tags require you to add the JSR-181 library to your project (available in the JDeveloper list of libraries)). Unlike the J2E WebService, the EJB session bean service is turned into a WebService upon deployment. This means you obtain teh WSDL file after deployment
    - Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean?
    The difference is that EJB Session bean based web services are integrated with the J2EE container, which means that they can leverage container services like transaction handling, data sources, security, JMS etc.

  • Invoking a AXIS Web Service with a Java object as input argument

    Hi
    I've been trying to execute a bpel process that invokes a web service deployed through axis.
    This web service takes a java object as input argument as opposed to data types that are directly mapped to java types through the SOAP engine.
    I deployed and tested the service outside of BPEL using a test client class. Everything works well.
    When I try to configure the "Assign" and "Invoke" activities so that service can be invoked, I cannot see the data structure through the variable picker and I see the following message:
    "The element {urn:ComplexTypeWebService}TimeSheetBean is not know to the schema container. Perhaps a schema file that uses it needs to include or import its definition.There mat also be an XML schema issue (non resolvable schema) which prevents {urn:ComplexTypeWebService}TimeSheetBean from being seen by the schema processor."
    Is there any example that demonstrates how to invoke an axis web service in such scenario? What am I doing wrong?
    Please, let me know.

    The passing of Java objects in and out of a web service is NOT supported. variables must be xml documents defined by a XML schema. In my opinion, missing Java object and WSDL is not a good idea. -Edwin

    Because you weren't told what to get, perhaps you already have it eh?
    What you want to read up about is JAX-WS, which is the webservice API bundled by default with your JDK (Java 6 and up). You'll find the wsimport tool in the bin directory of your JDK. I recommend you explore that directory and read up about all the executables you can find there, to be more prepared in the future. Know the tools you work with and all that. Most tools have a manual on this website:
    http://www.oracle.com/technetwork/java/javase/tech/index.html
    (under tools and utilities). Not wsimport, that is part of the jax-ws documentation. Better you look for jax-ws tutorials using Google, it will be quicker.

  • Invoking a web service from a java code

    Hello
    I created a simple Web service using JDevlper. It contains two methods
    1) getInf int () {
    return inf;}
    2) void setInf (int a) {
    inf = a;}
    I have deployed it on Oracle Application server. By inserting the address in a browser, I tried both methods and it works correctly.
    Here I am looking how to invoke this web service using a java client and use the method setInf (5 ) / * for example * /.
    I search but I have not found an answer that works :(. I hope you could help me to solve this problem.
    Thank you in advance

  • Calling a soap web service from a java desktop application

    Hi,
    Does anyone know how to call a soap web service from a java desktop application? I've seen examples using Apache Axis, but it sounds like Axis needs to run on a web server and we are trying to avoid that. My initial thought was that, "of course we need a web server", but I'm wondering if there is a way to do this without a web server.
    Any help is greatly appreciated.
    thank you,
    Julie

    If you are the consumer you don't need any web server. The web server is only needed in the provider end.
    In java 6 there is a built in framework to call web services without the need of third parties (such as apache axis)
    take a look at:
    https://jax-ws.dev.java.net/guide/Developing_client_application_with_locally_packaged_WSDL.html
    http://java.sun.com/webservices/technologies/index.jsp
    For the provider end there is also a built in http server to expose web service via HTTP without the need to
    use any external web server.
    take a look at:

  • Q: General : When will you use Web Service as opposed to just Servlet and/or EJB?

    Hi,
    I don't know if this is an appropriate question to ask for this class as it's not
    workshop
    specific. I was wondering how will I decide when it is appropriate to use a web
    service as opposed to say servlet or an EJB for my application? What is a good
    rationale to use?
    Thanks,
    Sadhana

    Hi Adam,
    Thanks a lot for giving such a lucid explanation of my vague question!
    I understand now the difference between when to use EJBs/Servlets/Web Services.
    Thanks again!

    Hi Sadhana,
    Web service versus Servlet versus EJB. Which one to use? That is a very
    good question.
    EJBs should be the core desription and processing of your business rules.
    They generally
    have good performance, are easy to integrate into your security set up but
    they require
    access using the RMI-IIOP protocol. This means that generally EJBs are not
    accessible
    outside of your firewall and their clients have to be written in Java (other
    enterprise
    objects or applets or GUI applications).
    Servlets often form a web-based front end to EJBs. They also have good performance,
    integrate into security and only require HTTP access. This means they are
    accessible
    outside your firewall and any client with a HTTP or web API can call on
    them, however,
    there is no standard contract or rules for this type of interaction so you
    will need
    provide direct input into development of the client.
    Web services are also accessible via HTTP and so can be accessed from outside
    your
    firewall. In fact, Web services internally within Workshop and WebLogic
    actually
    operate by using servlets and EJBs but the main advantage is that the mechanism/contract
    for interacting with the web service is a well defined standard (WSDL) and
    can actually
    be registered or retreived dynamically (UDDI). Since web service standards
    are open,
    most popular programming languages already provide client APIs to interact
    with them
    thus freeing the web service developer from direct interaction with the
    client developer
    and letting the client be developed on any platform. The penalty for this
    openness
    is a small performance hit (XML translation) and a slowly maturing security
    model.
    So in summary, use EJBs for business operations that have Java clients within
    your
    enterprise, use servlets to provide web style access to your business operations
    (like web pages) and use web services to enable automated clients that can
    be written
    on any platform either inside or outside your enterprise (firewall). In
    fact, it
    is common to write the EJB first and then to expose some parts of it outside
    of your
    enterprise by writing a web service wrapper (maybe using the EJB controls
    that we
    saw in class).
    I hope this helps.

  • Security: web services on WLS 8.5, ALSB and proxy on 9.1

    Hi everyone, here's my current situation. I've got some web services running on WLS 8.5, and I've imported them as Business Services into ALSB. The web services themselves are not secured, but I modified the WSDLs so that I could create proxy services which enforce the security.
    The security enforcement works when I test it through ALSB test console. However, now I'm trying to create a client web service to invoke the proxy. The client is being made using Workshop running on 8.5 server.
    I can get the client to successfully invoke the proxy with no policies attached. Then I made a proxy with BEA's Auth.xml required for inbound messages. The keystores are identical on both the proxy server and the client server.
    <input>
    <wsp:Policy>
    <wsp:PolicyReference URI="policy:Auth.xml"/>
    </wsp:Policy>
    <soap:body use="literal"/>
    </input>
    I imported the WSDL into workshop and created a java control from it. I attached a WSSE policy file to the control:
    <wsSecurityOut>
    <encryption>
    <encryptionKey>
    <alias>flcoi1</alias>
    </encryptionKey>
    </encryption>
    </wsSecurityOut>
    Added this control into a blank web service. The only error being returned from the server is:
    com.bea.control.ServiceControlException: SERVICE FAULT:
    Code:java.lang.NullPointerException
    String:null
    Detail:
    END SERVICE FAULT
    with no further explanations. Does someone know what would cause this exception? Or if it's even possible to do what I'm trying (between WLS 8 and 9)?

    Hi!
    In my tries to get security to work between WL 8.x to ALSB I realized that WL 8.x don't have support for WS-Security (and therfore WS-Policy) that ALSB uses, but maybe there are some workarounds...

    Thanks

    OK, then pls follow below steps;
    - Go to step 'Create Users' in solman_setup System Preparation scenario and make sure the user SM_INTERN_WS has a green status. Use the 'Test Login' button to make sure the user is not locked and has correct credentials maintained in solman_setup
    - Immediately after checking the user status, navigate to Configure Connectivity->Enable Web Services and execute again the 'Create Logical Ports' automatic activity, in order to propagate the correct credentials to the Logical Port definitions.
    - If the above operation is not successful, repeat the two steps above, providing a different user Id in 'Create Users' step, eg SM_INTERN_W1. This will prevent situations where the user gets locked by Logical Ports using an obsolete password.
    Let me know the results.

  • Web service functions in SSO without username and password

    Is there a way to use the Public Report Web Service functions when configured in SSO and without passing a username and password? I was able to try out the web service and make it work. As we all know, you need to pass a username and password for each web service call unless your reports can be accessed by guests. In an SSO + LDAP server configuration, there are cases in which you are not allowed to get the password. The password can not be decrypted.
    Is there a way to still use web service? or do you need to use the url approach instead? But if you use the url approach then you may be limited to generating reports only.
    I'm thinking there should be since if you are already logged in for SSO then you should be able to generate.
    Any way to configure this?

    <i>When I access web reports from bw.</i>
    i hope you are not talking about BEX web reports , since you have mentioned ITS.
    Is it a standlone ITS or intergrated ITS?
    can you post the url pattern here.
