Error invoking WebService in Eclipse with WebLogic 12c plugin

I am using Eclipse Indigo with WebLogic 12c plugin to create a standalone WebService Client which invokes a simple WebService. The WebService is protected by Security Policies Wssp1.2-2007-Wss1.0-X509-Basic256.xml and Wssp1.2-SignBody.xml.
I get the following exception when I run the standalone client:
h2. Exception in thread "main" java.util.ServiceConfigurationError: javax.xml.ws.spi.Provider: Provider weblogic.wsee.jaxws.spi.WLSProvider could not be instantiated: java.lang.ExceptionInInitializerError
The same program works fine using JDeveloper 11g but not in Eclipse Indigo or in Juno. Has anyone faced this issue?
Thanks,
Madhav

The stand-alone client JAR file does not, however, support invoking Web services that use the following advanced features:
Web services reliable SOAP messaging
Message-level security (WS-Security)
http://docs.oracle.com/cd/E14571_01/web.1111/e13760/client.htm#i229632
Can you try running by adding weblogic.jar. but if you run the client inside the wls Server it should work.
Regards,
Sunil P

  • How to integrate Oracle Enterprise Pack for Eclipse with Weblogic Portal

    Hi
    I am following this documentation http://download.oracle.com/docs/cd/E15919_01/wlp.1032/e14252/setup_dev_env.htm#i1013214
    to setup my development environment for developing portal applications, but I cannot set it up, my eclipse does not have PORTAL perspective.
    I have downloaded the Oracle Enterprise Pack for Eclipse 11gR1 (11.1.1.5) and the Oracle WebLogic Portal 10.3 as mentioned in the documentation.
    The Oracle Weblogic Portal 10.3 includes a workshop version of eclipse, but that is not based on a recent Eclipse, that is why I would like to use the Oracle Enterprise Pack for Eclipse 11gR1 (11.1.1.5).
    It is weird int he Oracle Portal 10.3 installation that I cannot install the Weblogic Portal without the Workshop.
    Could you help me in this? How can I integrate the Oracle Enterprise Pack for Eclipse with Weblogic Portal?
    Thank you.

    For WebLogic Portal tooling you have a couple of options. For WebLogic Portal 10.3 and older, Workshop for WebLogic will be your tooling environment.
    Starting in WebLogic Portal 10.3.2, which released this year, the development tools have migrated to Oracle Enterprise Pack for Eclipse. The WebLogic Portal 10.3.2 installer will install both the runtime and the IDE configured with additional WebLogic Portal Eclipse features (Portal Project Configuration, Perspecitives, Palettes, Deployment, etc).
    If you are interest in the latest version, you can download from the WebLogic Portal OTN page - http://www.oracle.com/technology/products/weblogic/portal/index.html

  • Issue with Weblogic 12c(12.1.2)

    My service is working as expected in weblogic 11g.Now we are upgrading to weblogic 12c.
    We are facing an issue of "NullPointerException" , due to the values, not getting  populated during server startup from ra.xml.
    In weblogic 11g the control is not going to that location, which is leading to an exception in Web logic 12c(NPE).
    If we validate the null values, control is invoking twice, one with null values and another time with actual values from ra.xml.
    Please help me on the same.
    Thanks & Regards

    Hi Sai,
    it did  not solve my issue. I am getting SocketException.The post you were talking about is BindException.
    Please help me if you can do something on this.
    Some where i have seen like this
    Using IPv6-Formatted Addresses
    Platform: All
    When using an IPv6-formatted address for WebLogic Server, the URL should include square brackets ('[' and ']') for the host address. Otherwise, WLST may fail to connect to the running server.
    Workaround
    Add square brackets to the host address. For example:
    t3://[fe80:0:0:0:203:baff:fe2f:59e5]:9991.
    But i dont know in which file these hosts contains.

    Any help would be appreciated. I have tried several approaches of class loading like <prefer-web-inf-classes> to true and referred CAT tool to add <prefer-application-packages> and etc. All results in some or other error.

    I could get rid of above error if I hard code the below line in CmisWebServicesSpi class.
    AbstractPortProvider portProvider = new WebSpherePortProvider();
    However, the next set of error I get is RuntimeException resulting from EclipseLink MOXy.

  • Error 403--Forbidden using eclipse and weblogic

    hi,
    i am new here on j2ee
    I am using eclipse3.4 and weblogic 9.1.2 on xp. I am trying to make simple hello world servlet
    here is what i did
    on the eclipse click New and click on Dynamic project
    click on Servlet and write following code for the servlet
    import java.io.IOException;
    import java.io.PrintWriter;
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;

                        "<h1>Hello Worldasd </h1></body></html>");
    folder structure and file web.xml is created by eclipse itself.
    then i started weblogic from the eclipse
    and i have following error

    Error 403--Forbidden
    From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

    The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.

    I do connect with router/modem
    eclipse did create weblogic.xml. here it is

    i did create a user proejct domain in weblogic.
    I did try by login through localhost:7001/console. but it didn't work. following is the problem
    Error 503--Service Unavailable
    From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
    10.5.4 503 Service Unavailable
    The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay may be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.
    Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection.
    any more suggestion will be helpful.
    this is just a start so please i need to solve this problem so that i can move ahead
    thanks

    Other solution:
    on refresh period, default value is 1 minute, force this value at 0 and your connection
    is ok.

    add a test table. DUAL is perfect for that. Everything else seems

  • Domain configuration with Weblogic 12c from ZIP archive

    Hi,
    for development purposes I have set up an Ubuntu Linux system and installed Weblogic 12.1.3 from ZIP archive following the instructions added with the archive (Oracle Fusion Middleware Software Downloads).
    But coming to the point where I want to create the domain, the documentation gets vague and I don't know exactly what to do and why the domain is not and no more scripts are created.
    Documentation states:
    It is recommended that you create domains outside the MW_HOME.
       Linux
        $ mkdir /home/myhome/mydomain
        $ cd /home/myhome/mydomain
        $ $JAVA_HOME/bin/java $JAVA_OPTIONS -Xmx1024m -XX:MaxPermSize=256m weblogic.Server
    So I did the following (normal user is named oracle):
    $ mkdir /home/oracle/chkdom
    $ cd /home/oracle/chkdom
    $ sudo su
    $ source /etc/profile
    $ $JAVA_HOME/bin/java -Xmx1024m -XX:MaxPermSize=256m weblogic.Server
    Weblogic Server starts and the directory structure is created. I am prompted for user credentials to start Weblogic server. But not more than the following output happens:
    No config.xml was found.
    Would you like the server to create a default configuration and boot? (y/n): y
    <06.11.2014 22:54 Uhr MEZ> <Info> <Management> <BEA-140013> </home/oracle/chkdom/config not found>
    <06.11.2014 22:54 Uhr MEZ> <Info> <Management> <BEA-141254> <Generating new domain directory in /home/oracle/chkdom.>
    What's going wrong?

    Okay, forget my posting.
    I had to wait more than half an hour and domain is created.

  • Round Robin was not happening for my cluster with WebLogic Proxy Plugin

              Hi,
              I configured my cluster with software load balancer, HTTPClusterServlet. By default,
              it is load balancing with Round Robin Algorithm. That means one HTTP request
              goes to server1, and the other HTTP request goes to server2. However, it is not
              what I can see no matter for the requests in one HTTP session or not.
              Say I open two browser, and log into my application with two different users,
              one is "cyang", the other is "xpression". Then the HTTP request (for servlet/jsp)
              from two browsers always go to the same server1, server2 is not invoked at all.
              I did see one time, with only one session (one browser with "xPression" user log
              in), the most requests go to server1, suddenly I am brough into log in page, then
              I noticed that the request for "xPression" moved to server2 although server1 is
              still alive. Therefore, at most, I can say it is "Random", rather than "Round
              Robin".
              What is the real meaning for HTTP servlet/jsp load balancing algorithm? Does
              Round Robin mean request go to each server in turns? Does it have to be different
              session or it can be within one session?
              

    It should be sticky. If not, then bug / config error.
