Reg: Lookup

Hi,
Can any one send me the steps how to use the lookup in ODI.
I have got source, source/lookup and target.
Thanks,
Gvel

Becker,
In that case you specify your join condition to de executed on Stage or Target environnement. In first case the target-based lookup tabe will be loaded into Stage area in order to be joined. In the other case the join will be done directly on Target environnement, while inserting/updating the Target Table.

Registry.lookup() return Remote object from different ip address

I've got this error using
Registry reg = LocateRegistry.getRegistry(serverName, Registry.REGISTRY_PORT);
service = (ILogin) reg.lookup("service");and when I use debugger I've got this
RegistryImpl_Stub[UnicastRef [liveRef: [endpoint:[10.240.161.66:1099](remote),objID:[0:0:0, 0]]]]
Proxy[ILogin,RemoteObjectInvocationHandler[UnicastRef [liveRef: [endpoint:[10.240.161.54:2074](remote),objID:[-4308ea07:116adade605:-7fff, 9133145996543447416]]]]]Why the Registry return a service from different IP address ?
I've run this code for several times and it works. But today it cannot connect to the RMIServer.
Any idea ?

Thanks, i found my missing prppertis is
// optional. Defaults to localhost. Only needed if web server is running
// on a different host than the appserver
props.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
// optional. Defaults to 3700. Only needed if target orb port is not 3700.
props.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
to set the port and host back

RMI call back - How to refer to the client project from the server project?

Hi, I am working on an RMI assignment which basically needs me to use the RMI call back for the server to notify the clients.
I have 2 projects , one for the client and another for the server.
In the client project, I have a client interface and the main client class implements this interface.
In the server project, I have a server interface and a class that implements this interface.
I can use the server interface in the client project's code by adding the server project in the path of the client project. it lets me use the server interface in the code if I put "import.." statement.
But the issue is I can not do the same to access the client interface from within the server project's code. Since that will be a circular reference, the compiler does not let me use the client interface from within the server's code. This is putting me in a great difficulty and I am stuck here. What should I do so that I can use the client interface and the compiler won't complain?
Thanks for any help..
Regards.. js

Let me explain what I tried: I manually generated stub class of the client using the Eclipse IDE as mentioned in my previous message. The StockMSClient_Stub.class got created in my client project.
The common project has the 2 interfaces - one from the client and one from the server.
I have added reference to the common project from the client and server projects to use the interfaces.
With the above mentioned in place, when I run the server project, the registry binding of the server objects is very fine. But I am getting error in the applet at the line where I am passing the client object to the method provided by the server interface. The following is the code snippet in the applet where I am getting the error.
specifically the line: String response = objs.login(userId, password, smsClient);     ====================
public void login() {
            Registry reg = null;
            String userId = "test";
            String password = "test";
            this.smsClient = new StockMSClient();
            try {
     reg = LocateRegistry.getRegistry(rmiHost,rmiPort);
                      UserInterface obj = (UserInterface) reg.lookup(rmiStrings
                                                                                                                    [1]);
     User u = obj.find(userId);
     if (u == null) {
          System.out.println("This user is not valid");
     } else {
                     UnicastRemoteObject.exportObject(smsClient);
     reg = LocateRegistry.getRegistry(rmiHost, rmiPort);
     LoginLogoutInterface objs = (LoginLogoutInterface) reg
                             .lookup(rmiStrings[0]);
                    //getting error at the following line.
                    String response = objs.login(userId, password, smsClient);
                     System.out.println("response :" + response);
           } catch (AccessException ae) {
                   System.out.println(ae);
           } catch (NotBoundException nbe) {
                  System.out.println(nbe);
           } catch (RemoteException re) {
                  System.out.println(re);
} //end login()====================
Error is:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
     java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
     java.lang.ClassNotFoundException: sms.rmi.graphics.StockMSClient_Stub (no security manager: RMI class loader disabled)================
I don't know why this is happening..Please help.

Dont think RMi is HTTP tunneling through proxy firewall

Hi Guys,
Does anyone know how to monitor if RMI is using the option toHTTP tunnel through a proxy ???
Many of clients sit behind firewalls/proxies that enable HTTP only. I thought RMI would, as a default, use HTTP tunneling POST, RESPONSe methods to get through, but it does not.
Would that case be insted of using Naming.lokup("RMIServer"); that i should use
Registry reg = LocateRegistry.getResgistry(serverAddress, serverPort);
reg.lookup("RMIServer");
Any help would be greatly appreciated.

RMI doesn't have an option like that. Sockets do, and you get it for any socket including RMI by setting socksProxyHost and socksProxyPort.
The RMI HTTP tunnelling thing happens when there is an HTTP server at the server side. which redirects the request to an RMI server via rmi-cgi.cgi or the RMI servlet. It's automatic, as a fallback, and you can enforce its use via a system property which you can find in the Javadoc Guide to Features/Remote Method Invocation/Useful java.rmi system properties.

Cannot invoke remote method

can you please tell whatis wrong in the program.

How to compile package which contain class outside the package

I am writing a JDBC driver.
I have the following package structure in the folder:
MyDriver
    |_manager.jar
    |_com
           |_ jdbc
                   |_ HXDriver
                   |_ HXConnection
                   |_ HXResultSet
                   |_ HXStatementIn manager.jar, there is a remote object Interaface(Manager.java) which I need to use inside HXConnection.
My question is how to compile(or/and how to set the classpath)so that I can compile the 4 classes inside jdbc package.
I tried this:
C:\MyDriver>javac -cp .;manager.jar com/hx/jdbc/*.java
However, this does not work, compiler says it cannot find Manager
Please help me.
Cheers

Problem connecting RMI-Server using a servlet

Hi All..
I have a RMI-client server model woring fine in AIX box.I am currently in a need to create one web client(may be with servlet or JSP).
I wrote a sample servlet which try to connect to the RMI server. But when I run the servlet Its simply try to connect and then wait for unlimited time,not even print any exception/error.
Both my RMI sevrer and Tomcat are in the same box.
I am sending the servlet code for your reference.
import java.rmi.*;
import java.rmi.registry.Registry;
import java.rmi.registry.LocateRegistry;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import ir77.mon.engine.*;
public class WebClient extends HttpServlet
public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
XmlServerIntf xmlServerIntf = null;
PrintWriter out = res.getWriter();
res.setContentType("text/plain");
try{
out.println("Connecting to server......");
//Seems this one is sufficient.(either this code or the below one)
//String strServerUrl = "rmi://" + "192.168.100.22" + "/ir77.mon.engine";
//xmlServerIntf = (XmlServerIntf) Naming.lookup(strServerUrl);
//Try with this one also
Registry reg = LocateRegistry.getRegistry("192.168.100.22", 2004);
xmlServerIntf = (XmlServerIntf) reg.lookup("rmi://192.168.100.22/ir77.mon.engine");
out.println("Connected to server");
catch (Exception e){
System.out.println("Exception in WebClient"+e);
when I run the servlet in the browser with "http://192.168.100.22:8080/WebClient" its simply prints " Connecting to server......" and waits.
Note : 192.168.100.22 - where my rmi server starts and 2004 -where I created by rmiregistry.I created it using LocateRegistry.createRegistry(2004);
I have tried starting tomcat with "-security" option too but no responds as well.
Do I have to provide some grant permission in catlina.policy file?If yes what?
currently I have tried with giving all permission..
Do I need to change the RMI server code?
Any help will be highly appreciated....

Hi genady,
Oh....Ya I like to...I thought no body was interested...as I didn't get any reply from anybody....
Well The first thing is that with the look up method in the servlet
it should be like :
Registry reg = LocateRegistry.getRegistry("ip address of the rmi server", port number);
RMIServerInterface = (type cast with RMIServerInterface) reg.lookup("rmi binding string");
Now you are able to get the server interface object & you can call any method.
Next you have to provide the grant permission in the catalina.policy file to the folder where you have your application like....
grant codeBase "file:${catalina.home}/webapps/ROOT/WEB-INF/classes/-" {
permission java.security.AllPermission;
Or you can give specific permissions also.
Finally you have to run the tomcat as : $catalina.sh start -security
Note: One more thing you have to keep in mind that's the structure of your application. ie com.mon.yourapp.......u have to create the same structure in tomcat's classes folder .
Its done...........

Starting and stopping an RMI server

I'm trying to figure out how to best stop and start my server.
My server class has two executions. One for starting and one for stopping.
Start Steps:
1) create my remote object ( an extension of UnicastRemoteObject )
2) create a registry ( LocateRegistry.create() )
3) bind my remote object
When I run this start method of my RMI server class, everything get's set up. I'm not doing any sort of waiting loop or anything to determine the lifecycle of my server. My understanding is that my rmiregistry, and my registered remote object, will continue to be available indefinitely. Perhaps this is incorrect.
Stop Steps:
When I want to stop the server, I'm calling my stop method. This is another invocation of my server class, so it's a separate JVM. In this stop method I want to do the following steps:
1) get the registry that I created earlier, by port number
2) get my remote object via reg.lookup()
3) unbind my remote obect ( reg.unbind() )
4) unexport my remote object ( UnicastRemoteObject.unexport ( myRemoteObj, true ) )
My concerns here are whether this makes sense. Does the unexport method work like this? i.e. from a remote handle to the object -- I'm not in the local JVM when the stop method runs. Also, does the rmiregistry "just die" at this point? It's not holding anything and when my method exits there's no reference to it anywhere. Except maybe in client code . . .

My understanding is that my rmiregistry, and my registered remote object, will continue to be available indefinitely. Perhaps this is incorrect.That's correct as long as you store static references to them both in the server JVM.
My concerns here are whether this makes sense. Does the unexport method work like this? i.e. from a remote handle to the objectNo. You have to have the actual remote object. You could make shutdown() an RMI method itself.
Also, does the rmiregistry "just die" at this point?No, you have to unexport that as well.

NoRouteToHostException

I've seen a few other threads with this issue, but I'm not quite sure why I'm having the issue.
I'm running the RMI server and client on the same linux box. The server starts up on port 1099 and binds the object without issue.
I start the client and can list the available objects, but when I attempt to invoke one of the mehtods, I get the NoRouteToHostException.
I updated the CouponServicesLinkImpl default constructor to call the super constructor with 1099, but I think this is overkill.
Any thoughts?
Client Code
    public static void testClient() throws Exception
        Registry reg = LocateRegistry.getRegistry("localhost");
        String[] list = reg.list();
        System.out.println( list[0] ); // <<----successfully lists "CouponServices"
        CouponServicesLink link = (CouponServicesLink)reg.lookup("CouponServices");
        System.out.println( link.toString() ); // <<----Shows Proxy[ISPRemote,RemoteObjectInvocationHandler[UnicastRef [liveRef: [endpoint:[XX.XX.XX.XX:1099](remote),objID:[-536e44f3:129a950f14b:-7fff, -8506899594546368628]]]]]
        link.invokeRetrieveProcessAsRecords(); // <<-----thorows java.rmi.ConnectIOException: Exception creating connection to: XX.XX.XX.XX; nested exception is:        java.net.NoRouteToHostException: No route to host
        link.cleanup();
    }Server Code:
            System.out.println( "creating registry @ 1099");
            Registry registry = LocateRegistry.createRegistry(1099);
            System.out.println( "Creating object for registry");
            CouponServicesLink stub = (CouponServicesLink)new CouponServicesLinkImpl();
            System.out.println( "Binding CouponServices");
            registry.rebind( "CouponServices", stub);
            System.out.println( "Waiting for Clients");
        } catch (Exception e) {
            System.err.println("exception:");
            e.printStackTrace();
        }

Gotcha. That corrected the issue and I appreciate the resource information.
Is there an explanation about why the RMI server logic can properly serve the listings without the hostname property, but cannot serve the objects without it? Or is that just "the way it is".

RMI connection refused

Hello to all,
I have created and completed an RMI chat application and tested it on my localhost. It worked all right.
Now I want to make it live i.e. run it through internet.
Is it same as running on localhost only we have to change the IP address for locating registry.
I have done that and uploaded the server file on host, also I have the IP address of that host.
I have replaces localhost whit the give IP address but connection refused exception is thrown.
I have located the registry on the server through IP address then when I use
Registry reg=LocateRegistry("xx.xx.xx.xxx");
System.out.println("1");
chatAppIF chatStub=(chatAppIF)Naming.lookup("rmi://xx.xx.xx.xxx:xxxx/service");
System.out.println("2");
int i=chatStub.logMeIn(user,pass);
System.out.println("3");Output screen shows
1
2
Client exception: java.rmi.ConnectException: Connection refused to host: xx.xx.xx.xxx; nested exception is:
java.net.ConnectException: Connection refused: connectWhile when i use
Registry reg=LocateRegistry("xx.xx.xx.xxx");
System.out.println("1");
chatAppIF stub=(chatAppIF)reg.lookup("service");
System.out.println("2");
int i=chatStub.logMeIn(user,pass);
System.out.println("3");it give output as
1
Client exception: java.rmi.ConnectException: Connection refused to host: xx.xx.xx.xxx; nested exception is:
java.net.ConnectException: Connection refused: connectIs there is difference between naming.lookup() and reg.lookup() method?
I think Naming.lookup() finds the registry but cannot find the method logMeIn() while reg.lookup() has no success.
anyway why the connection is refused?

The argument to Naming.bind()/rebind()/unbind() and Naming.lookup() is a URI of the form rmi://hostname[:port]/path.
The argument to Registry.bind()/rebind()/unbind() and Registry.lookup() is just the path part.
The data returned by Naming.list() is an array of URIs.
The data returned by Registry.list() is an array of paths.
In other words Naming.list() returns items which can be used as arguments to Naming.lookup(), and Registry.list() returns items which can be used as arguments to Registry.lookup().
The reason is that when you construct a Registry, via LocateRegistry.getRegistry(), you supply the host and port at that point, so specifying it again in the bind/lookup string would be redundant. There's nothing stopping you doing that but the resulting name won't be compatible with what Naming.bind() would have done.

Using Applets and RMI on WL6 - Error marshaling transport header; nested exception is: - java.io.EOFException

I have a project that I am porting from WL5.1 to WL6. It was working fine
in WL5.1
but cannot get it working in WL6. So, I went back to the HelloWorld
example to
see if I could get it working. The problem I am having is basically getting
applet to
talk to a server via RMI. The applet works fine alone and RMI works fine
alone.
I can't get the applet to talk to the server via RMI.
I am trying to get the "HelloWorld" applet example in WL6 working with RMI.
I previously had the same app working in WL5.1 with SP9 but cannot get it
working in WL6.
I am running WebLogic Server 6.0 with SP2.
I have registered a startup class in the WebLogic console
named "HelloServer". When starting up the server, it states
that the HelloImpl class has been registered as "HelloServer".
When starting up the client applet I get the following error:
java.rmi.MarshalException: Error marshaling transport header; nested
exception is:
java.io.EOFException
These are two different methods of looking up the same object.
The exception occurs at the "lookup" method call in both cases.
"myserver" is the name of my machine that WL is running on.
7001 is the port that WL is using.
Registry reg = LocateRegistry.getRegistry("myserver", 7001);
obj = (Hello)reg.lookup("HelloServer");
or...
obj = (Hello)weblogic.rmi.Naming.lookup("rmi://" +
getCodeBase().getHost() + ':' + port + "/HelloServer");
I previously ran this same program under WL5.1 SP9 and everything works
fine.
I defined the startupClass in the weblogic.properties file in WL5.1
Can anyone tell my what is causing this exception and how to correct the
problem?
Thanks

Unmarshalling arguments Problem

I'm new to RMI. I opened the rmi registry on windows , tried to run my server , but every time I run this server I get the exception:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:

public class Server implements MyRemoteServer{
    public String sayHi() {
        return "Hi , I'm the fuckin' server.";
    public Server() throws RemoteException{
    super();
}I searched for the answer and I noticed there is something called code base, Is this my problem ,If any one has an idea please let me know.

Thanks I used c , and it worked , but when I tried to run the client I got an exception:

RMI Doesn't Work Over Firewall

Hi,I need urgent help!!! I am writing a RMI server which will be hosted behind the firewall and the client could be anyone. I started my RMI server but I have problem connecting to it. Here's my codes:
If you look at the Client.java class, my code got as far as:
Registry reg = LocateRegistry.getRegistry("216.16.45.33", 2001);
I could get the registry but the lookup of "MyServer" failed. I encounter, the "java.rmi.ConnectException: Connection refused" at the Client side.
More info:
I am using Linksys router and I have already set the router to forward all traffics at port 2001 and 2999 to go to the computer that hosts the RMI server. Can someone point me to the right direction? THANKS GUYS!!!!

On what platform (Linux or windows) your server is running?
And more important, what IP address this server has?
When it tries to bind object to IP that is not set to this machine, then it fails. RMI server does not say any error or something...
I had the same problem. I added second interface (linux command):
ifconfig eth0 xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is my public IP.

REG: RFC lookup

Hi all,
In my scenario i need to use RFC lookup for the receiver system . Can u guys suggest me a method how to implement the RFC lookup.
Thanks,
Siva.

Hi,
Check this blogs for the steps:
1)Use this crazy piece for any RFC Mapping Lookups!
2)The specified item was not found.

Reg : RFC Lookups

Hi..
Now i have a scenario for u instead :
this is what gimme a solid realistic approach :
i have records in this format lets say :
RecordID   ordertype
900           0305
900           0305
920           DS01
900           0304
900           0305
920           DS02
Now here is what i have look into :
for all 900's whose Ordertype is same i have to make a call and then to decide to create/change by an RFC Lookup, with this RFC Lookup i have to then decide on which IDOC i have to map to . So that means i have to sort all the records of 900's based on ordertype with in the mapping itself and then make a call to IDOC .
I am not expecting whether to use XSLT / Java mapping , I can only use custom functions. Lemme know whatz the best approach?
for all 920's its not that complex but all 920 goes to one IDOC.
Any clue?
regards..sankar

Hi Michal,
>>>>>I'd go with Shravan's approach for sure
please send link for this, i do not have shravan's approach?
Hope you got my problem: or else see follow:
I am outlining the scenarios here :
I have a flat file with a following type of records:
RecordID   ordertype
900           0305    ..............................
900           0305    .............................
920           DS01 .............................
900           0304 .........................................
900           0305 .....................................
920           DS02 .......................
930    -->not concerned with these type of records
Now here is what i have look into :
for all 900's whose Ordertype is same i have to make a call and then to decide to create/change by an RFC Lookup, with this RFC Lookup (i.e. i have to group all the records with ordertype same ) i have to then decide on which IDOC i have to map to .
i.e. For all 900's with one ordertype if i find that there exists an OPEN_PO then i have to call one IDOC with one set of values along with values returned from that RFC
if its OPEN_PO is blan that i should send values to another IDOC
for all 920 records i have to call another IDOC .
I am not expecting whether to use XSLT / Java mapping , I can only use custom functions. well lemme know whatz the best approach?
Please help
thanks,
regards
sankar
