Calling remote EJB from Weblogic 8.1 to websphere 5.1

Hi, I'm trying to get a connection from my weblogic 8.1 to a EJB in a websphere 5.1
I'm connecting via IIOP without seurity, first I have a problem with the connection, in the server log appears:
<b>java.net.UnknownHostException: remoteDNS:remoteDNS</b>
but, it appears not at the beginning the connection, it appears when the EJB I've called, returns me the method I invoked and my weblogic didn't recognize the remote server because it have to return a DNS or IP: port and it doesn't occour, I'm not behind a FW.
Then I made modifications to the sever I register some websphere jars in the classpath but when I made this another problem become, the log shows me a message that says that the initialcontext class could not be loaded, and when I modified the classpath to recognize this the other parts of my site breakdown because their initialcontext were different.
Basically, I want some help in How to make the connection to websphere via IIOP or another protocol and what are the requeriments that I need to modify in my Weblogic, and in my class of connection.
I almost tried to make a network channel to comunicate to the websphere but it didn't work.
Can anybody give me suggestions on what to try??
Thanks

I believe there is a document that describes this.
Java EE 4 interop requires that you do not need to put WebSphere
ORB/ICF classes in your WLS classpath and vice versa. You should
simply be able to make EJB refs to the remote side using an
appropriate corbaloc URL.
Can you post your EJB config and code?

    The procedure apex_cdc.enable_table_capture i created myself with no authid mentioned explicitly, so it uses definer rights, by default.
    BUt this procedure is simply a wrapper for sys.dbms_cdc_publish.create_change_table.
    When I look on the security model for this sys.dbms_cdc_publish, i see it runs under invoker rights. (http://www.psoug.org/reference/dbms_cdc_publish.html).
    The code is like this:
    CREATE OR REPLACE PROCEDURE enable_table_capture
              i_owner               IN VARCHAR2,

  • Can I call an EJB from the database?

    Hi,
    I've just spent the last few days attempting to call an EJB from a stored procedure in a 10g database (and still haven't succeeded).
    Now having spent hours searching the web (and this forum) for any successful examples (so far I have found none) I thought I'd add a message to see if there is anybody out there who has done this successfully. If so can you please provide me some details on how to do this?
    Alternatively, I'd appreciate any input on how I can overcome my current hurdle in attempting to do this myself.
    Here's how far I've got in my attempt:
    I have a simple stateless session bean deployed to both Oracle 10gAS (a standalone OC4J container in 10.1.3) and to Weblogic 9. I have a client java class that calls a method on this bean and displays some ouput if successful. This all works from a standalone JVM (version 1.4) on both Weblogic and 10gAS.
    I then tried to load the required libraries for Weblogic onto the database (namely the Weblogic.jar file). This resulted in the addition of some 32,000 odd objects of which 30,000 odd could not be resolved. I figured a lot of these may be down to JVM version issues (I believe that Weblogic 9 uses the 1.5 JRE) so I decided to put the Weblogic test on the back burner for now and just use the Oracle app server.
    The tests with the Oracle app server looked promising. I only needed a handful of libraries to be loaded onto the database and all the relevant classes required for my test client had resolved (including the initial context factory required to do the jndi lookup of the bean). After granting all the permissions I believed I needed I'd got to the point where I could do a jndi lookup of the EJB; but when I tried to create an instance of the beans remote interface I got the following error:
    java.security.AccessControlException: the Permission (java.lang.RuntimePermission getClassLoader) has not been granted to ProtectionDomain (file:generated/by/proxy <no certificates>)

    Has anybody come across this before? If so can they help?
    If not has anybody out there actually managed to call an EJB method (without going via an RMI server/Servlet/or any other proxy).
    Any help in this matter would be greatfully appreciated.
    Cheers,
    Anand.

    Sure, here's the code. It's what JDev generates automatically but I have seperated some things into several diffrent lines so I could experiment easier.
    final Context context = getInitialContext();
    Object o=context.lookup( "SessionEJB4" );
    Object l= PortableRemoteObject.narrow( o, SessionEJB4Home.class );
    final SessionEJB4Home sessionEJB4Home = (SessionEJB4Home)l;
    SessionEJB4 sessionEJB4 = sessionEJB4Home.create();
    String ret=( sessionEJB4.hello( ) );
    As I mentioned, for this I have used EJB2.1 bean, because I had same problems with EJB3.0, so I tried earlier versions of Java to make sure that is not the problem.
    hello() method just returns string "hello".
    Of course, this works in standalone client that is not loaded into database.
    Now, I loaded all the jars mentioned in this thread, using loadjava options -v -resolve, and I loaded client using options -v -resolve -genmissing . Select query on user objects in database shows that client class and relevant classes are all valid.
    Then I created stub and ran it. First it stopped throwing exception ORA-29532: Java call terminated by uncought Java exception: Java.lang.NoClassDefFoundError.
    Method I try to run returns String value which is hello message if it works fine, else it prints the part of the stack trace. In this case, after p[revious error, When I try to run it again, i get return from the method :
    Lookup error: java.lang.NoClassDefFoundError; nested exception is:
         java.lang.NoClassDefFoundError
    com.evermind.server.rmi.RMICall.throwRecordedException(RMICall.java:89)
    com.evermind.server.rmi.RMIClientConnection.waitForJndiResponse(RMIClientConnection.java:371)
    com.evermind.server.rmi.RMIClientConnection.lookup(RMIClientConnection.java:179)
    com.evermind.server.rmi.RMIClient.lookup(RMIClient.java:283)
    com.evermind.server.rmi.RMIClientContext.lookup(RMIClientContext.java:51)
    javax.naming.InitialContext.lookup(InitialContext.java:347)
    simpleejbproject.EJB4Client.hello(EJB4Client.java:35)
    Of course, regular version of the client I run frokm command line works fine.
    So I'm kind of a stuck here. I followed all directions, tried it on oracle 9 and oracle 10 DB, the problems remain the same. Am I missing something here?
    Thanks
    Just to add, getInitialContext()
        private static Context getInitialContext() throws NamingException {
            Hashtable env = new Hashtable();
            // Oracle Application Server 10g connection details
            env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.rmi.RMIInitialContextFactory" );
            env.put( Context.SECURITY_PRINCIPAL, "oc4jadmin" );
            env.put( Context.SECURITY_CREDENTIALS, "manager1" );
            env.put(Context.PROVIDER_URL, "opmn:ormi://mserv:4005:home/TestEjb4");
            return new InitialContext( env );
    It goes withouth any exceptions.

    Did you package your JSPs in a WAR and your EJBs in a JAR and package the
              WAR and JAR in an EAR? That is how to do it in 6.0. Works well.

  • Urgent!!!!How to deploy only an EJB from Weblogic to oc4j.

    Hi
    How can i deploy only EJB from Weblogic into oc4j without any web application or client coming into pitcture as my client access bean remotely....
    regards,
    Sapthapathi

    If you are migrating from ejb1.1->ejb1.1 you shouldn't have many changes - your ejb-jar.xml file should be the same (I assume you are still talking about ejbs). Once you pull over the base ejb - then if you want to, mess around with the automatically generated orion-ejb-jar.xml file. Obviously - those are all app server specific. I go back and forth between wls6.1 and oc4j all the time. When going from wls5.1 to oc4j - what particular issues do you run into. What do you mean, in particular, by configuration changes?
    Curious -
    Ray
    hi,
    EJBs and other applications can be migrated from weblogic to oc4j but many changes are required.These changes are mainly configuration changes rather than code changes.Infact there are many problems in effect while migrating and delloyment.Hope oracle is a bit more attentive to this issue.

    i'm having a problem in lookingup my remote EJB from my
    jakarta application.
    That exact code works perfectly if I run it standalone. I
    am using the same JRE. Jakarta has also loaded the
    openejb-0.8.3.jar and openejb_client-0.8.3.jar
    What I dont understand is why jakarta
    would behave differently than command-line java when I
    am
    running in the same JRE on a single machine.
    Any help would be much appreciated.

    Several fairly major improvements have been maid in OpenEJB specifically for the Tomcat people. For one, the whole way you integrate them has completely been rewritten. Now all you have to do is copy a openejb_loader-0.9.1.war into the Tomcat webapps directory and change an init-param in it. Pretty straight forward. OpenEJB 0.8.3 won't work with Tomcat in the same VM, however OpenEJB 0.9.0 and up have been totally revamped in all things related to classloading so that it can co-exist with Tomcats unique classloading architecture.
    O'Reilly just published an article detailing the ins and outs of the integration, it's a pretty good read:

  • How to call remote API from root SharePoint 2013 domain (not an app)

    I'm trying to follow the article
    http://msdn.microsoft.com/en-us/library/office/fp179895%28v=office.15%29.aspx
    For a SharePoint 2013 hosted under O365, do I need to create an app to use the SP.* methods in sp.js? I need to call a remote API from the root domain (https://mycompany.sharepoint.com). But the app, as mentioned in the article
    above, deploys on a whole different URL (https://mycompany-a2d3f4t454.sharepoint.com).
    I need to be able to call the API from pages like https://mycompany.sharepoint.com/pages/default.aspx. Is this not possible?

    Hi,
    According to your description, my understanding is that you want to call remote API from the root domain site.
    Yes, you can use SharePoint hosted app to achieve it. SharePoint hosted app has app web and host web, you can create an app to call the remote api in the host web from app web.
    Here are some detailed articles for your reference:

  • Challenge: call local ejb from remote ejb on weblogic 9.2

    Hi ALL,
    How do I call to local ejb from remote ejb object. The jar file is deployed on weblogic server 9.2, if you want get it http://geocities.yahoo.com.br/lindembe/BEAProject.jar and the source code are http://geocities.yahoo.com.br/lindembe/BEAProject.zip. It is a sample app with two ejb that works so good on JBOSS, JOnAS, but BEA Weblogic.....
    The complete problem you watch http://forum.java.sun.com/thread.jspa?threadID=768718&messageID=4387570#4387570
    or
    http://forums.bea.com/bea/message.jspa?messageID=600043148&tstart=0

    Your code in SigemFacadeBean should just do:
    InitialContext ctx = new InitialContext();
    when you lookup the local EJB. (This will work on all app servers. There's no need to put an app-server specific intial context factory in your code.)
    Also, you can remove the jndi-name setting for the local ejb from your weblogic-ejb-jar.xml. jndi-name is only applied to remote ejbs.

    Hi,
    I didn't configure the JNDI stuff in WLS per se. I created a simple session bean and the meta data in the jar of this determined the JNDI setup.
    Once this is deployed on either WLS it can then be seen in Weblogic Console by clicking on View JNDI Tree. The full JNDI name is present and correct on both WLS to which it is deployed.
    Does that answer your questions or are you asking how I configured the SOA Suite composite? In which case I selected the EJB in the Partner Link swimlane. Viewed the properties and added
    java.naming.provider.url

  • Problem in calling Local EJB in weblogic 7.0

    Hi,
    I'm calling a Local Ejb from a client application, but i'm getting the following exception
    Exceptionjavax.naming.NameNotFoundException: Unable to resolve 'local' Resolved:
    '' Unresolved:'local' ; remaining name 'local'

    But I have given the correct JNDI name in the deployment descriptor and whereever necessary
    If any one knows abt this, pls reply back, its urgent
    Thanks in advance

  • Calling Remote interface from client

    Hi there!
    I am working on a BMP (using weblogic 6.1)
    My problem is - How do I contact remote interface from client. In my jndi tree I have mentioned only Home interface. Right now I am calling my remote interface like this:
    //contact home interface
    Object obj = ctx.lookup("APIHome");
    APIHome home = (APIHome) javax.rmi.PortableRemoteObject.narrow(obj, APIHome.class);
    //creating remote somehow - I got this clue from a website
    rem = home.findByPrimaryKey(new EntityPK("test1","test2"));
    //calling getter & setter methods
    rem.setWidth()
    rem.getId();
    This works...but doesn't make any sense to me. Why should we initialize remote interface as above. Or is there any other option. Can somebody please explain me more clearly about this concept.
    Thanks very much
    regards
    -Manasvi

    The HomeInterface contains two types of methods - create and find. The create methods create an instance of the entity bean(i.e., a record in the database) and the finder methods finds an existing record in the database, constructs an entity bean representing this row and returns the remote interface of this bean to the client for further manipulations.

  • Connecting to Remote EJB from Servlet in same application

    Please help!
    I was able to connect to SessionBeans and EJB from my sample java client in OCJ4 but when I try to do same thing from my web application using servlets, I get the below NullPointerException error.
    The JNDI lookup works fine using java client but difficult from a servlet.

    SessionCartEJBHome home = (SessionCartEJBHome)jndiContext.lookup("SessionCartEJBBean");

    WARNING: Unhandled Exception thrown: class javax.ejb.EJBException

    Avi,
    Thanks for your response. I am actually returning a new InitialContext in a function call in the servlet. What I have noticed though is that JDeveloper creates two ear files for the application. One for the ejbs called ejb1.ear and another for the web files webapp1.ear. These are located in the applications subdirectory in OC4J directory.
    I know I have two projects in the application, model and viewController. I am just trying to follow the MVC pattern.
    In short, I don't think the web and the ejbs are in same ear file. I made the web project depend on the ejbs though. There is an option to set such. I don't know how to tell JDeveloper to put them all in one ear file.
    I will appreciate any suggestion.
    Thanks
    Matilda
