Rmic -iiop error

Hi all,
when trying to compile my RMI implementation class with rmic -iiop I get the following exception:
[918] rmic -iiop com.siemens.mobile.omip.core.oam.v10>
error: java.rmi.server.RemoteServer is not a valid remote implementation: has no remote interfaces.
1 errorWithout option -iiop rmic works fine (also my RMI object does).
Any hints welcome ...
Regards, Hounce

My implementation extends PortableRemoteObject.
But your right, this was the problem, because my ant-task <rmic> also compiled some older stuff (still derived from UnicastRemoteObject), therefore I recognized no change in the error message when introducing the PortableRemoteObject like stated in the RMI-IIOP Programmer's Guide http://java.sun.com/j2se/1.3/docs/guide/rmi-iiop/rmi_iiop_pg.html.
Thanks a lot,
Hounce

Rmic -iiop not creating _Stub

Hi,
I am compiling in 1.4 using rmic -iiop - it is not creating the Stub class (it only creates the Tie class). Anything I need to do for that to happen.
As a consequence when error when I run my RMI Server
Error starting service: RemoteException- java.rmi.StubNotFoundException: Stub class not found:
Thanks a lot,
Sanjay

I am doing that:
public interface IAccountService extends java.rmi.Remote {....
public class AccountServiceImpl implements IAccountService {....
I am compiling :
rmic -iiop AccountServiceImpl
This creates the AccountServiceImplTie.class but not the _Stub
Thanks a lot,
Sanjay

Jdk1.3.1 bug with rmic -iiop?

Hi
Does anyone know whether there is a bug with the rmic -iiop feature of jdk1.3.1?
When I try to use rmic -iiop, with the -classpath option, it throws a java.lang.ClassFormatError.
e.g.
rmic -classpath .;C\irfeclient\requestrecord.jar -iiop com.ch.irfe.curvegen.xtools.CurveGenImpl
If I leave out the current directory when setting the classpath, the compiler says it can't find the implementation class com.ch.irfe.curvegen.xtools.CurveGenImpl.
If I just try using rmic without -iiop, it works. However I need to generate iiop stubs.
Has anyone managed to resolve this one?
many thanks
Lyndsey

I've done some further investigation and I think it is a bug with jdk1.3.1. I have tried using IBMs JDK that comes with WebSphere 3.5, and it works fine.

how can i fix those errors... anybody..please help!!!!

Hi
I get exactly the same error message.
Did you manage to fix it?
If so, can you tell me how!
Appreciated.

Re: Errors compiling the rmi-iiop example.

As I said, apparently, you are trying to compile the IDL client in java using the RMI client classes. THere are two problems with this:
1-- you must compile the rmi class definitions into a directory that can be easily excluded from the class path at the time you compile the idl definitions.
2-- the idl definitions and the resulting classes are useless wrt the rmi definitions and wls, so the resulting classes must be compiled into directories other than those used by wls and the rmi clients.
Another way to look at this is as follows:
To compile the rmi definitions, you do:
set ORIGINALCLASSPATH=CLASSPATH
set CLASSPATH=../fooclasses;$CLASSPATH
javac -d ../fooclasses rmi/FooImpl.java
Then,
-- you compile the jrmp classes as:
rmic -d ../jrmpclasses rmi.FooImpl
-- you compile the weblogic classes as:
java weblogic.rmic -d ../wlsclasses rmi.FooImpl
that is, you are allowed to compile from the same implementation class so long as it is compliant
-- you compile the rmi-iiop classes as:
java weblogic.rmic -iiop -d ../rmiiiopclasses rmi.FooImpl
that is, as with jrmp and wls, the rmi-iiop classes share the same base type definitions and implementation.
However, the idl classes are another matter. To compile the idl classes, you must generate the idl, generate the java files and generate the idl class files into another, separate directory, one which does not include any of ../fooclasses, ../jrmpclasses, ../wlsclasses or ../rmiiiopclasses
directories.
That is,
java weblogic.rmic -idlDirtecory ../idl ...
set CLASSPATH=ORIGINALCLASSPATH
set CLASSPATH=../idlclasses;CLASSPATH
cd ../idl
idl2java rmi/Foo.idl
javac -d ../idl rmi/*.java
Hope this helps...

I created a Resource Bundle in the src directory a WSAD project. It's named Messages_en_US.properties. I've tested getting strings from this resource bundle, in an ejb, on Websphere, at runtime and it works fine.
The problem comes when I want to create a static enum class which references this resource bundle. When I do that and run Generate RMIC, I get the following error in a window:
com.ibm.etools.rmic.RMICException: RMIC Command returns RC = 1. The problems which stopped RMIC are displayed, and have also been recorded in the log file.
Then in the log file, I get this exception:
!MESSAGE java.lang.ExceptionInInitializerError: java.util.MissingResourceException: Can't find bundle for base name com.retek.mdm.app.attribute.service.impl.Messages, locale en_US

Apparently, because I created a static variable, RMIC tries to instantiate it, and then it can find it. Any ideas?
Thanks,
Tim

Not sure if this is the answer but...
Websphere starts it's Web container after it's EJB container. If the class that tries to call that is in the ejb level it might not have read the property file yet because that is in the web level.
We had this problem and it was traced back to the threading of the start up.

RMI/IIOP HelloWorld problem

I saw this topic in an old thread but couldn't find the answer. My
problem was the same, the client app was stuck at the line
obj = nc.resolve(path);
Could you post your solution if you know the answer to this problem.
Thanks a lot.

Yes, you are right. I'm currently using jdk1.3. Is there a fix or do I
have to go back to jdk1.2? Thanks a lot.

I think that was the problem. How do I fix that?

As I said, apparently, you are trying to compile the IDL
client in java using the RMI client classes. THere are two
problems with this:
1-- you must compile the rmi class definitions into a
directory that can be easily excluded from the class path at
the time you compile the idl definitions.
2-- the idl definitions and the resulting classes are useless
wrt the rmi definitions and wls, so the resulting classes must
be compiled into directories other than those used by wls and
the rmi clients.
Another way to look at this is as follows:
To compile the rmi definitions, you do:
set ORIGINALCLASSPATH=CLASSPATH
set CLASSPATH=../fooclasses;$CLASSPATH
javac -d ../fooclasses rmi/FooImpl.java
Then,
-- you compile the jrmp classes as:
rmic -d ../jrmpclasses rmi.FooImpl
-- you compile the weblogic classes as:
java weblogic.rmic -d ../wlsclasses rmi.FooImpl
that is, you are allowed to compile from the same
implementation class so long as it is compliant
-- you compile the rmi-iiop classes as:
java weblogic.rmic -iiop -d ../rmiiiopclasses rmi.FooImpl
that is, as with jrmp and wls, the rmi-iiop classes share the
same base type definitions and implementation.
However, the idl classes are another matter. To compile the
idl classes, you must generate the idl, generate the java
files and generate the idl class files into another, separate
directory, one which does not include any of ../fooclasses,
../jrmpclasses, ../wlsclasses or ../rmiiiopclasses
directories.
That is,
java weblogic.rmic -idlDirtecory ../idl ...
set CLASSPATH=ORIGINALCLASSPATH
set CLASSPATH=../idlclasses;CLASSPATH
cd ../idl
idl2java rmi/Foo.idl
javac -d ../idl rmi/*.java
Hope this helps...

Error Starting WebLogic Server 5.1 (SP11)

Hi,
I have installed weblogic server 5.1 (SP11) in NT, I tried to start the Weblogic
Server and got the message "weblogic server started", immediatly after that I
got the message " IIOP service not started as vm 1.3 was not found". Do you know
what could be causing these IIOP error message?. Any help.
Thanks in advance,
RChandra

51 SP11 is shipped with IIOP stuff and by default this sub-system is enabled.
If you don't want IIOP, you can turn it off with the following system property
-Dweblogic.system.enableIIOP=false weblogic.Server
Otherwise make sure to start the server with 1.3 VM .

Why cann't rmic find the class?

I have write some RMI Code,and I could compile them correctly,but when I wanted to generate Stub and Skel by rmic ,it showed me that:
E:\JavaPro\CH21-05>rmic RmiTestServer
error: Class RmiTestServer not found.

I don't know why?
Here the source which helps to understand the problem:

How can I solve this problem?

I made it by runing the following command line:
rmic -classpath E:\JavaPro\CH21-05 RmiTestServer
and it created two files: RmiTestServer_Skel.class and RmiTestServer_Stub.class
Thank you very much!

Obtaining an IOR for RMI-IIOP

Hi -
I'm working to modify a C program (gnuplot) so that it can remotely call functions in Java.
My current plan is to use RMI-IIOP on the Java side. I'd like to create a class that implements java.rmi.Remote via some local implementation class, instantiate it, then obtain a stringified IOR for that object and pass it to gnuplot, which can then use the IOR to call remote methods.
Also, I'm planning to use CORBA DII on the client side, since I want a generic program where the remote method names can be set by user options at run time.
Does this make sense? I'm working with this tutorial code:
http://java.sun.com/j2se/1.5.0/docs/guide/rmi-iiop/tutorial.html
and am stuck on obtaining an IOR in the server code.
Any help would be appreciated...

Well, I figured it out. The key method is remoteToCorba in com.sun.jndi.toolkit.corba.CorbaUtils. Here's my server code:
//HelloServer.java
import java.io.*;
import org.omg.CORBA.ORB;
import com.sun.jndi.toolkit.corba.CorbaUtils;
public class HelloServer {
    public static void main(String[] args) {
        try {
            // Step 1: Instantiate the Hello servant
            HelloImpl helloRef = new HelloImpl();
            // Step 2: Initialize the ORB
            ORB orb = ORB.init(args, null);
            // Step 3: Convert the Hello servant to a CORBA object
            org.omg.CORBA.Object corba_obj;
            corba_obj = CorbaUtils.remoteToCorba(helloRef, orb);
            // Step 4a: Announce the IOR to STDOUT
            String ior = orb.object_to_string(corba_obj);
            System.out.println("IOR: " + ior);
            // Step 4b: Announce the IOR to a file
            FileWriter fw = new FileWriter("hello.ior");
            fw.write(ior);
            fw.close();
            System.out.println("Hello Server: Ready...");
         } catch (Exception e) {
            System.out.println("Trouble: " + e);
            e.printStackTrace();
}And here's the matching client code:
//HelloClient.java
import java.io.*;
import org.omg.CORBA.ORB;
import javax.rmi.PortableRemoteObject;
public class HelloClient {
    public static void main( String args[] ) {
        HelloInterface hi;
        try {
            // Step 1: Initialize the ORB
            ORB orb = ORB.init(args, null);
            // Step 2: Obtain the stringified IOR from a file
            FileReader fr = new FileReader("hello.ior");
            BufferedReader br = new BufferedReader(fr);
            String ior = br.readLine();
            // Step 3: Convert the IOR to a CORBA object reference
            org.omg.CORBA.Object objref = orb.string_to_object(ior);
            // Step 4: Narrow the CORBA object reference to the concrete type
            hi = (HelloInterface) PortableRemoteObject.narrow(
                objref, HelloInterface.class);
            // Step 5: Invoke the method.
            hi.sayHello( " MARS " );
        } catch( Exception e ) {
            System.err.println( "Exception " + e + "Caught" );
            e.printStackTrace( );
            return;
}The other two files are unchanged from the original example:
//HelloInterface.java
import java.rmi.Remote;
public interface HelloInterface extends java.rmi.Remote {
   public void sayHello( String from ) throws java.rmi.RemoteException;
//HelloImpl.java
import javax.rmi.PortableRemoteObject;
public class HelloImpl extends PortableRemoteObject implements HelloInterface {
   public HelloImpl() throws java.rmi.RemoteException {
       super();     // invoke rmi linking and remote object initialization
   public void sayHello( String from ) throws java.rmi.RemoteException {
       System.out.println( "Hello from " + from + "!!" );
       System.out.flush();
}Compilation and usage is straightforward:
javac *.java

Simple RMI/IIOP app : "no security manager: RMI class loader disabled"

Hello colleagues!
I do not understand the problem at all, and asking for your kind help.
This is my first code for RMI/IIOP. We are using JBoss as application server.
What I've done :
1) created test.Command interface , extending Remote
2) created test.CommandImpl , implementing above mentioned interface and java.io.Serializable, and extending javax.rmi.PortableRemoteObject.
BTW, Serializable is not implemented in some tutorials, but absence of Serializable causes NotSerializableException when trying to rebind (next step).
3) in server code, created initial context and called
context.rebind("test/Command",new CommandImpl());
4) Ran rmic -iiop test.CommandImpl . A result was two new cass files, CommandImplTie.class and CommandStub.class , both are also in package "test".
5) Created remote client and put CommandStub.class to client
classpath (under package "test", too).
6) In client code, initialized the context and called
context.lookup("test/Command").
On this line (lookup), the following exception is being raised :
javax.naming.CommunicationException. Root exception is java.lang.ClassNotFoundException: test.CommandImpl (no security manager: RMI class loader disabled)

Is _Stub class all that client needs from server classes, to obtain
the reference ? I tried to put _Tie also to client, but with the same result.
All Jndi paths to JBoss server are correct, as I've used them successfully in other applications.
Many thanks in advance,
Daniel

Next few words to the topic.
I made tests with canonical RMI/IIOP tutorial from Sun.
When I use Sun's ORB (orbd.exe) , everything work fine. I started
orbd on the same PC as JBoss, and client and server are running
remotely.
But with JBoss ORB, I have the same exception as described above.
Server starts and registers in JNDI successfully, but client can not
obtain a remote reference. Exception is being thrown on
context.lookup().
So the difference is definitely in security managers for two ORBs.
I also tried to create new RMISecurityMananger and set it, but with
no effect.
Any ideas ?
TIA,
Daniel.

ClassCastException for RMI-IIOP client hitting CORBA server

I am writing a RMI-IIOP client to connect to an existing CORBA C++ server. I started out with writing a RMI Interface mimicking the IDL and then converting into a stub using rmic -iiop option. I then use COSNaming to connect to the server. When I narrow the reference using PortableRemoteObject.narrow(), I get a ClassCastException. Probably because the object that I get from naming service will be a CORBA object which cannot be casted to RMI Interface object.

I am writing a RMI-IIOP client to connect to an existing CORBA C++ serverAs it says in [the Javadoc|http://java.sun.com/j2se/1.5.0/docs/guide/rmi-iiop/rmiiiopUsing.html#when], you can't do that. For RMI/IIOP you have to start with a PortableRemoteObject and rmic -iiop. You can use a C++ client to that but you can't use an RMI/IIOP client to a C++ server.
Use IDLJ.

C++/RMI-IIOP

Hello,
I am fairly new to the RMI-IIOP technology. I basically have remote objects written in Java. I wish to call them via a C++ client. Are the following steps correct?
1. compile the remote object classes
1. rmic -iiop on the remote object to get the Stub and Tie classes
2. rmic -idl on the remote object to get the IDL files
3. run idl->C++ compiler to get the C++ stubs
4. write a C++ client that calls the remote object
5. start the orb
6. start the server
7. run the client
Any help/ pointer to sample code will be greatly applreciated
Thanks
AP

Problems with rmic v1.1

Hi,
I have to use the JDK1.1.8, if I compiled the interface and the implementation of the interface everything was fine.
But when I try to create my stub and skeleton with rmic, I get this message:
rmic prog
error: File ./prog.class does not contain type prog as expected, but type my.test.prog.prog. Please remove the
file, or make sure it appears in the correct subdirectory of the class path.
error: Class prog not found.

By convention, most java tools expect to find a "packaged" class in a directory hierarchy that relects the packaging. In other words, a class defined like
com.myco.myapp.ImportantApplication.class
will be placed under a base directory, in a subordinate directory thus:
/basedir/com/myco/myapp
In turn, java tools will find this class if you suppli classpaths such as
java -classpath basedir/
Note the trailng slash. This tells java that this is a directory name.
rmic works the same way.

Difference between Java IDL and RMI-IIOP

Hi,
I am new to CORBA / RMI and I am trying to clear my concepts a little bit. Suppose, we want to create a remote object that should be accesible from CORBA clients. Does anyone know what the difference is between creating this object as an RMI object (with RMI-IIOP) and using the java IDL?
In other words, if I am not wrong, it is possible to write the object in java (pretty much like writting an RMI remore object), generate the IDL with rmic and then any CORBA client can access it provided it has the IDL.
Are there any advantages in doing it the other way (explicitely instantiating an ORB in the code, etc) ?
By the way, if we use the first choice (RMI-IIOP), when is the ORB getting called? Is it called by the Tie class, which is generated by rmic -iiop?
Thanks!
