[java rmi] PortableRemoteObject method not referenced

Hello everyone.

I use a portable proxy between an IIOP client and server of connection JRMI (activated). While the proxy has an active reference on the login server, it cannot execute his method not referenced. So I try to use the source not cited in the proxy too, but once he gets a reference to the login server (the first time a user IIOP calls the PortableProxy.login () method, the replacement no quoted source method is never called.

It's my proxy code:
public class PortableProxy extends ClientAuthentication, Unreferenced{
     private String path = System.getenv("WORKDIR");
     private ClientAuthentication authLogin = null;
     private static final String authServer = "authServer";
     private static final int authServerPort = 1098;
     private static final String authServerIP = "localhost";
     private static final int portableProxyRMI = 3500;
     private static final String portableProxy = "PortableProxy";
     /**
        * PortableProxy()
        */
     public PortableProxy(){
          Properties prop = new Properties();
          Object obj = null;
          System.setProperty("javax.net.ssl.trustStore",""+path+"client/mySrvKeystore");
          System.setProperty("javax.net.ssl.trustStorePassword", "123456");
          try{
               PortableRemoteObject.exportObject(this);
                  System.setProperty("java.rmi.dgc.leaseValue", "12000");
                  System.setProperty("java.rmi.dgc.checkInterval", "6000");
          }catch(RemoteException re){
               System.out.println("PortableProxy.PortableProxy() RemoteException: "+re.getMessage());
               re.printStackTrace();
          }
          System.out.println("PortableProxy exported");
     }
     
     /**
        * lookRef()
        */
     public void lookRef(){
          Properties prop = new Properties();
          Object obj = null;
          prop.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.rmi.registry.RegistryContextFactory");
          prop.put(Context.PROVIDER_URL, "rmi://"+authServerIP+":"+authServerPort);
          InitialContext ic = null;
          try{
             ic = new InitialContext(prop);
             obj = ic.lookup(authServer);
          }catch(NamingException ne){
             System.out.println("PortableProxy.lookRef() NamingException: "+ne.getMessage());
             ne.printStackTrace();
          }
          authLogin = (ClientAuthentication) PortableRemoteObject.narrow(obj, ClientAuthentication.class);
   }
     
     /**
        * login()
        */
     public Runnable login(String user, String password){
          System.out.println("Sono in PortableProxy.login()");
          Runnable ret = null;
          if(authLogin == null){
               lookRef();
          }
          try{
               ret = authLogin.login(user, password);
          }catch(RemoteException re){
               System.out.println("PortableProxy.login() RemoteException: "+re.getMessage());
               re.printStackTrace();
          }
          return ret;
     }
     
     /**
        * unreferenced()
        */
     public void unreferenced(){
          authLogin = null;
          if(authLogin == null){
               System.out.println("authLogin = null");
          }else{
               System.out.println("Something went wrong: authLogin != null.");
          }
          System.gc();
     }

     /**
     * MAIN
     */
     public static void main(String[] args){
          Properties prop = new Properties();
          PortableProxy proxy = new PortableProxy();
          prop.put("java.naming.factory.initial",  "com.sun.jndi.cosnaming.CNCtxFactory");
          prop.put("java.naming.provider.url", "iiop://localhost:"+portableProxyRMI);
          try{
               InitialContext icProxy = new InitialContext(prop);
               icProxy.rebind(portableProxy, proxy);
          }catch(NamingException ne){
               System.out.println("PortableProxy.main() NamingException: "+ne.getMessage());
               ne.printStackTrace();
          }
     }
}
I closed all the user jvm, but nothing happened. I don't have a reference to the proxy each time, I put it to null.
Where I am doing wrong?
PS: I also want to set the leaseValue and the checkInterval for a shorter time. In this way (under the PortableRemoteObject.exportObject (()) the right way?
Tell me thanks in advance, if you need additional information. Thank you

In my view, that the unreferenced support is available only when the use standard rmi. the iiop based RPC does not support distributed gc.

    I saw that in your SOAP load is a field named body. Rename this field, and then try again.

    get error below when running the code above through driving the demand, but he worked for 1 print the line, but when it's on a loop, it throws this error.

    The Java Exception: java.lang.reflect.InvocationTargetException: during the java.lang.reflect.Method .invoke call.

    I came across the same thing as you. I did a lot of experimenting and found it works:

    var result = (function() {
        var ReflectiveArray = java.lang.reflect.Array;
        var CreateSQL = Packages.PeopleSoft.PeopleCode.Func.CreateSQL;
        var columns = ReflectiveArray.newInstance(java.lang.Object, 1 /* number of selected columns */);
        var results = [];
    
        SQL = CreateSQL("SELECT OPRDEFNDESC FROM PSOPRDEFN WHERE ROWNUM < 10");
        while (SQL.Fetch(columns)) {
            results.push(columns[0]);
        }
    
        return results.join();
    
    }());
    

    He seems to have been a problem with translation between the JavaScript array and the Java array Object []. I solved this by using java.lang.reflect.Array.newInstance to create a new instance of the object [1].

    Next issue to deal with is your memory problem. In the error message, it seems to have something to do with the Garbage Collection and a lot of temporary objects. You declare you line and cell by using the var =... line and cell var =...? If not, then they are in the global namespace and properties of the global object. At the end of each iteration of the loop, use delete line and delete cells. If you declare the var, then set their value null at the end of each iteration. Based on your code, I expect each time through the loop would decrease the number of references, but I saw where setting explicitly using null. The only other temporary object I see is the value in the table. Just for fun, I added this at the end of each loop, and he ran very well:

    columns[0] = null;

    Hello
    Problem is solved.
    In configuration of weblogic-ejb - jar.xml for EJB module, he was trying to get the server in clustered environment, while we have no configuration of the clustered environment
    in the DEV environment. We have commented on the part of the cluster in this config file. Also we were faced with question class version so we used JDK 1.6 for the generation of client project and ear local jar that weblogic uses JDK 1.6.

    Thank you...

  • EN the error using the grid java.rmi.UnmarshalException

    Hello


    I started using Hyperion Financial Reporting on the remote machine and now I installed it on my machine.

    Everything was ok during the installation process. Then I tried to create a new report with a new grid. When I click on the button, EN gives me the following error:


    ********


    ; nested exception is:

    java.rmi.UnmarshalException: error demarshalling return; nested exception is:

    java.io.InvalidClassException: com.hyperion.reporting.graphics.GridObject; incompatible local class: stream classdesc serialVersionUID =-1288366423950156093, local class serialVersionUID =-5245705824007679661

    ********

    Can someone explain to me what I can do to fix this error?

    In my experiences, it gives me this error when a report have a grid or when I try to create a.

    It is perhaps at a level different patch, EN can be sometimes not work so well when the client and server versions do not match.

    See you soon

    xdoxslt sum allows us to avoid the issue while fields sum with the value null. as you already now the condition with the field u do not need xdoxslt

    is - enough try this

    you are able to get a preview of the template with the code of the sum.

    Send me your model and xml. I can try at my side

  • java.rmi.ConnectException: connection refused to host: Connection timed out

    OK, I get the dreaded java.rmi.ConnectException: connection refused to host: Connection timed out

    I've been Googling for solutions for a while and no success, although many people have been in this boat before.

    java.rmi.ConnectException: connection refused to host: 169.254.105.9; nested exception is:
    java.net.ConnectException: Connection timed out: connect

    I ping the server from the client. I can telnet to the 169.254.105.9 1099 very well. I have disabled all firewall, I think - although company policy is we have to run McAfee and seems to have no control over that. When I run the client and server on the same system using localhost everything works fine.

    Can anyone think of other things I could try to understand why my RMI does not connect? Are there diagnoses more I can try?

    Cheers, Eric

    System.setProperty call ("java.rmi.server.hostname", "150.247.94.130");

    has no effect. I call it on the side of the client and the server before making any calls to the RMI API. I always get

    Set it on the server only. That's what it's for. It touches what IP address is placed in the heel when exporting. If you need to call it before you build/export all remote objects, and that probably includes the registry.

  • ProcessTemplate method not found.

    Hi all

    I'm having a rough with the processTemplate class which I hope one of you can help me with.

    First some facts about the system.

    JDeveloper 9i RUP 7.
    XMLP 6.5.3
    Oracle APPS 11.5.10CU2

    I have the following code:

    ...
    dataTemplate.setOutput("/home/appsdev/kkristoff/KKR_TEST_1.xml");
    dataTemplate.processData ();

    OutputStream outputStream = new FileOutputStream("/home/appsdev/kkristoff/KKR_TEST_1.pdf");
    InputStream inputStream = new FileInputStream("/home/appsdev/kkristoff/KKR_TEST_1.xml");

    Properties prop = new Properties ();

    Process template
    TemplateHelper.processTemplateFile (appsContext, / / AppsContext)
    'BKFND', / / short name of the Application of the model
    "HelloReport", / / model model code
    'fr', / / the model ISO language code
    '00', / / ISO of the model territory code
    inputStream, / / the XML data in the model of
    TemplateHelper.OUTPUT_TYPE_PDF, / / output the procesed document type
    prop, / / properties of the treatment model
    outputStream); OutputStream where goes the transformed document.

    inputStream.close ();
    outputStream.close ();

    When I Isaiah to compile the project, I get the following error:

    method processTemplateFile (oracle.apps.fnd.common.AppsContext,
    java.lang.String,
    java.lang.String,
    java.lang.String,
    java.lang.String,
    java.io.InputStream,
    Byte,
    java.util.Properties,
    java.io.OutputStream) is not found in the oracle.apps.xdo.oa.schema.server.TemplateHelper class

    The javadoc for the API tells me that I can use the following method:

    public static void processTemplate (pContext, oracle.apps.fnd.common.AppsContext,
    java.lang.String pAppName,
    java.lang.String pTemplateCode,
    java.lang.String pLanguage,
    java.lang.String pTerritory,
    java.io.InputStream pData,
    pOutputType bytes,
    java.util.Properties pProp,
    PPerformance java.io.OutputStream)

    I checked the class oracle.apps.xdo.oa.schema.server.TemplateHelper to a method described above and which exists.

    Can someone please tell me why JDeveloper complaints regarding this call to the processTemplate method?

    Thank you in advance.

    Kenneth

    Hello

    Use ProcessTemplate method instead of ProcessTemplateFile.

  • enableThemes method not found in the oracle.lbs.mapclient.MapViewer class

    Hello
    I would ask about the error I recently.
    I don't know what's wrong with my code, but I '_enableThemes_ method not found in the class oracle.lbs.mapclient.MapViewer' when I tried to apply a theme to my card using the API of Java Bean.

    Another method does not recognize mapviewer is '_setAllThemesEnabled_ '.

    I don't know how to apply some themes I did for my card despite the use of the method.
    I have already imported oracle.lbs.mapclient.MapViewer.

    I really appreciate your help...

    Hello
    Make sure that you type the correct setting. EnableThemes method requires an array of strings. Try the following:

    mv.enableThemes (new String() {"THEMENAME"});

  • Is there a self-cleaning of the TABLEs not referenced after surgery impdp?

    Assume the following sequence of operations:

    (1.) I export a complete database with expdp in a dumpfile
    2.) I create a new TABLE "mytab" (resp. more generally a object). References/entries in this table will be added to a couple of tables system "all_tables", "dba_tab_privs" and others.
    3.) now I import the previously exported dumpfile to return in the original database with parameter
    TABLE_EXISTS_ACTION = REPLACE FULL = Y

    This operation would replace the table "all_tables' (resp. the table behind this point of view system).
    The reference to "mytab" is getting lost. This is similar to an object that is not referenced in C++ (which must be released) or an object not referenced in Java that is removed by the garbage collector.

    How such an orphaned table/object is managed in Oracle?

    Is there a!-up or a warning?

    Peter

    If you create a table after you export and an import complete export the table you created after that export has been carried out, mytable in your example, should not be affected by import. RDBMS database tables are not superimposed my full import rather the DDL created as part of the export updates base tables.

    Where the table exists the create table in dmp file errors out and impdp (or imp) just ignores the error and continues to stage data loading. The stage of loading data capture and does not take into account continuous duplicate key errors to try to insert data until there is no more to this table, then he goes to try to create the index for the table.

    At least that's how exp/imp has worked and I have not noticed any behavior change with expdp/impdp, although I haven't used utilities heavily again.

    HTH - Mark D Powell.

    Note: the above applies when you import in the db of the source, and not another where you expect changes once the dmp file was made to not be present in the default behavior for a full import to do not destroy the existing database and re-create dmp file. To re-create the tablespaces was the default behavior with version 6.
