Problems with RMI Codebase

Hello,
i have installed Tomcat in a path with whitespaces. Our Application use RMI (as server componend) to communicate with other Applications.
when I start Tomcat i get an Exception like this:
(by the way: no protocol: Audit -> Audit is a part of the path with whitespaces and it is nessessary that the tool runs with whitespaces in the path e.g. Program Files)
java.rmi.ServerException: RemoteException occurred in server thread; nested exce
ption is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested excep
tion is:

Please help me, its urgent.
Best regards

Hi Chris,
the Exception java.net.MalformedURLException: no protocol: Audit means that your path is incorrect, try
<protocol>://<path>/
for Example

i don't know if it helps but i had the following problem:
an rmi-component software plus a servlet contacting the system.
and rmi from the servlet in tomcat did not seem to work ...
java.rmi.MarshalException: error marshalling arguments; nested exception is:

finaly i changed back to tomcat 4.0.x but it still was not any better, when i found out that most of the problems resulted from pathnames...
tomcat 4.1.24 had a problem with pathnames getting too long (2k on win 2000) and tomcat 4.0 produced errors because of the blank in it's path name "Tomcat 4.0" so i made a new installation with C:\Tomcat4 as home directory and - what a surprise - things turned out fine and rmi worked.

Problem with RMI in ADB T75 receiver

Hi:
I have a problem with an xlet that uses the RMI (IXC) API in the ADB T75 development settop box.
I export an object (of type MyObject) implementing the Remote interface, and, later, I import it with no problem.
The problem appears after importing the object, when I try to cast the imported object to the type of the exported object (type MyObject) for using it (example on page 371 of the marvelous Morris book).
If I import the object in the same xlet where I export it (a little bit useless), the process works fine as the class of the imported object (remoteObject.getClass().getName()) is the same of the exported object.
But, when importing the object from another xlet, doing the cast fails (ClassCastException). This time, remoteObject.getClass().getName() returns the name "stub_MyObject_ca_ba" ( "ca" is the OrgID and "ba" is the AppID of the exporting xlet). That is, the middleware is returning to the importing xlet an object of the stub class.
The ClassCastException seems to be right, as the the superclass of the "stub_MyObject_ca_ba" is directly java.lang.Object. That is, the types of the exported object (MyObject) and the returned object (stub_MyObject_ca_ba) are not in the same hierarchy.
Has anyone one explanation or solution?
May be a bug of the ADB T75 settop box?
Thanks in advance for your comments

Problem solved. This was posted by Pretorius_594 on Feb 27, 2004.
Sorry for bothering.
The problem was due to that I was doing a cast to the original object (MyObject). That is:
remoteObject = lookup(...)
MyObject importedobject = (MyObject)remoteObject.
I saw such an example in the Morris and Smith-Chaigneau book, but, definetively, that code seems not to work (at least in the ADB receiver)
Th right solution is to extend the Remote interface (MyRemote) and to cast the importedobject to that type. That is:
public interface MyRemote extends Remote ...
remoteObject = lookup(...)
MyRemote importedobject = (MyRemote)remoteObject.

Trouble with RMI codebase

Hi, i've created a file transfer application via RMI, it work very well, i can transfer file longer than 1 GB without any problem.
But when i copy my project with all classes to another directory, it doesn't work. I'm sure that the trouble is in the VM options :
"-Djava.rmi.server.codebase=file:E:\RMIFileTransfer\classes\ -Djava.security.policy=file:E:\RMIFileTransfer\policy\RMI.policy ", that points to the old directory. I don't want to change "E:\RMIFileTransfer\" in the VM options each time i move my project!!!
How can be java.rmi.server.codebase and java.security.policy properties setted by an user input, or in the main( String args[] ) method? (sorry for my bad english...)

(a) use a JAR file, not a directory system
(b) the codebase setting has to have the same meaning throughout the system, i.e. to the server, the registry, and the client. Obviously a file: URL is not likely to comply, because every host has its own file system. Have a look into providing the JAR file via an HTTP service and using an http: URL.

Problems with RMI

hi friends,
I am doing my project in grid computing.I am using RMI. but sometimes what happens is when i submit the jobs to the machines and after completion when i collect the values and display the output, sometimes i am not able to get the whole image completed back.Some part of the image doesn't appear there. What might be the proble?

The problem might be that you do not provide any details and expect us to be visionaries...

Problem using CORBA clients with RMI/EJB servers..!!!???

Hi,
I have a question on using EJB / or RMI servers with CORBA clients using
RMI-IIOP transport, which in theory should work, but in practice has few
glitches.
Basically, I have implemented a very simple server, StockTreader, which
looks up for a symbol and returns a 'Stock' object. In the first example, I
simplified the 'Stock' object to be a mere java.lang.String, so that lookup
would simply return the 'synbol'.
Then I have implemented the above, as an RMI-IIOP server (case 1) and a
CORBA server (case 2) with respective clients, and the pair of
client-servers work fine as long as they are CORBA-to-CORBA and RMI-to-RMI.
But the problem arises when I tried using the RMI server (via IIOP) with the
CORBA client, when the client tries to narrow the object ref obtained from
the naming service into the CORBA idl defined type (StockTrader) it ends up
with a class cast exception.
This is what I did to achieve the above results:
[1] Define an RMI interface StockTrader.java (extending java.rmi.Remote)
with the method,
public String lookup( String symbol) throws RMIException;
[2] Implement the StorckTrader interface (on a PortableRemoteObject derived
class, to make it IIOP compliant), and then the server to register the stock
trader with COS Naming service as follows:
String homeName =....
StockTraderImpl trader =new StockTraderImpl();
System.out.println("binding obj <" homeName ">...");
java.util.Hashtable ht =new java.util.Hashtable();
ht.put("java.naming.factory.initial", args[2]);
ht.put("java.naming.provider.url", args[3]);
Context ctx =new InitialContext(ht);
ctx.rebind(homeName, trader);
[3] Generate the RMI-IIOP skeletons for the Implementation class,
rmic -iiop stock.StockTraderImpl
[4] generate the IDL for the RMI interface,
rmic -idl stock.StockTraderImpl
[5] Generate IDL stubs for the CORBA client,
idlj -v -fclient -emitAll StockTraderImpl.idl
[6] Write the client to use the IDL-defined stock trader,
String serverName =args[0];
String symList =args[1];
StockClient client =new StockClient();
System.out.println("init orb...");
ORB orb =ORB.init(args, null);
System.out.println("resolve init name service...");
org.omg.CORBA.Object objRef
=orb.resolve_initial_references("NameService");
NamingContext naming =NamingContextHelper.narrow(objRef);
... define a naming component etc...
org.omg.CORBA.Object obj =naming.resolve(...);
System.out.println("narrow objRef: " obj.getClass() ": " +obj);
StockTrader trader =StockTraderHelper.narrow(obj);
[7] Compile all the classes using Java 1.2.2
[8] start tnameserv (naming service), then the server to register the RMI
server obj
[9] Run the CORBA client, passing it the COSNaming service ref name (with
which the server obj is registered)
The CORBA client successfully finds the server obj ref in the naming
service, the operation StockTraderHelper.narrow() fails in the segment
below, with a class cast exception:
org.omg.CORBA.Object obj =naming.resolve(...);
StockTrader trader =StockTraderHelper.narrow(obj);
The <obj> returned by naming service turns out to be of the type;
class com.sun.rmi.iiop.CDRInputStream$1
This is of the same type when stock trader object is registered in a CORBA
server (as opposed to an RMI server), but works correctly with no casting
excpetions..
Any ideas / hints very welcome.
thanks in advance,
-hari

On the contrary... all that is being said is that we needed to provide clearer examples/documentation in the 5.1.0 release. There will be no difference between the product as found in the service pack and the product found in the 5.1.1. That is, the only substantive will be that 5.1.1 will also
include the examples.

With reference to your and other messages, it appears that one should not
expect that WLS RMI-IIOP will work in a complex real-life system, at least
not now. In other words, support for real-life CORBA clients is not an

We currently publish an IDL example, even though the IDL programmingmodel in Java is completely non-functional, in anticipation of the support
needs for uses who need to use IDL to talk to the Weblogic server,
generically. This example illustrates the simplest connectivity; it does not
address how
to integrate CORBA and EJB, a broad topic, fraught with peril, imo. I'llnote in passing that, to my knowledge, none of the other vendors attempt
this topic either, a point which is telling if all the less happy to hear.
For the record then, what is missing from our distribution wrt RMI-IIOPare a RMI-IIOP example, an EJB-IIOP example, an EJB-C++. In this you are
correct; better examples are forth coming.
Still, I would not call our RMI-IIOP implementation fragile. I would saythat customers have an understandably hard time accepting that the IDL
programming model is busted; busted in the sense that there are no C++
libraries to support the EJB model, and busted in the sense that there is
simply no
support in Java for an IDL interface to an EJB. Weblogic has nothing to doit being busted, although we are trying to help our customers deal with it
in productive ways.
For the moment, what there is is a RMI (over IIOP) programming model, aninherently Java to Java programming model, and true to that, we accept and
dispatch IIOP request into RMI server objects. The way I look at it is this:
it's just a protocol, like HTTP, or JRMP; it's not IDL and it has
practically nothing to do with CORBA.

Eduardo,
Can you give us more details about the comment below:
I fear that as soon as the call to narrow succeeds, the remainingapplication will fail to work correctly because it is too difficult ot
use an idl client in java to work.It seems to me that Weblogic's RMI-IIOP is a very fragile
implementation. We
don't need a "HelloWorld" example, we need a concrete serious example(fully
tested and seriously documented) that works so that we can get a betteridea
on how to integrate CORBA and EJB.

Please post request to the news group...
As I said, you must separate the idl related classes (class files and
java
files) from the rmi classes... in the rmic step, you must set a newtarget
(as you did), emit the java files into that directory (it's not clearyou
did this), then remove all the rmi class files from the class path... ifyou
need to compile more classes at that point, copy the java files to theidl
directly is you must, but you can not share the types in any way.
I fear that as soon as the call to narrow succeeds, the remainingapplication will fail to work correctly because it is too difficult otuse
an idl client in java to work.

Hi Eduardo,
Thanks for the help. That is the way I compiled my CORBA client, by
separating the IDL-generated stubs from the RMI ones, but still I
get a
CORBA.BAD_PARAM upon narrowing the client proxy to the interfacetype.
Here's what I did;
+ Define the RMI interfaces, in this case a StockTrader interface.
+ Implement RMI interface by extendingjavax.rmi.PortableRemoteObject
making
it IIOP compliant
+ Implemnnt an RMI server, and compile using JDK1.2.2
+ use the RMI implementation to generate CORBA idl, using RMI-IIOPplugin
utility rmic;
rmic -idl -noValueMethods -always -d idl stock.StockTraderImpl
+ generate Java mappings to the IDL generated above, using RMI-IIOPplugin
util,
idlj -v -fclient -emitAll -tf src stocks\StockTrader.idl
This creates source for the package stock and also
org.omg.CORBA.*
package, presumably IIOP type marshalling
+ compile all classes generated above using JDK1.2.2
+ Implement client (CORBA) using the classes generated above, NOTthe
RMI
proxies.
+ start RMI server, with stockTrader server obj
+ start tnameserv
+ start CORBA client
Then the client errors when trying to narrow the obj ref from the
naming
service, into the CORBA IDL defined interface using,
org.omg.CORBA.Object obj =naming.resolve(nn);
StockTrader trader =StockTraderHelper.narrow(obj); // THIS
ERRORS..!!!
throwing a CORBA.BAD_PARAM exception.
any ideas..?

Please see the post on june 26, re Errors compiling... somewherein
there,
I suspect, you are referring to the rmi class file when you are
obliged
to
completely segregate these from the idl class files.

Problem in Rmi in machine with two IP local & internet

I am having problem in Rmi in machine with two interfaces local & internet
i.e..
if I set property java.rmi.server.hostname+ to the one with internet ip address using System.setProperty()
I can not access Rmi through local LAN
if I do not set the property Everything works fine in LAN but I can not access the RMI from Internet
Pls tell me the solution

Application to use Weblogic 6.0. All the rmi services run in an
external VM seperate from the WL server. This setup works fine with
plain RMI, I have converted this to WL and JNDI. I get the following
error after a few connections to the service have been made. It always
happens.
<Feb 18, 2001 10:53:39 PM EST> <Error> <ConnectionManager> <Closing:
'weblogic.r
jvm.t3.T3JVMConnection@91cee' because of: 'Client received a routed
message from
an unknown JVM: '-5623439693736234706C:24.185.83.208''>
I have taken the Stock Applet example from WL5.1 and it also exhibits
the same problems. Since there are no examples with RMI and JNDI in
WL6 maybe I am missing something. I create an initial an IntialContext
and I can list and see any objects. But I will always wind up getting
these errors that Peer has shutdown because a message has been
received from an unknown VM. I have dumped out the info of and the
message is coming from a "known" VM but the weblogic rmi subsystem
seems to have lost the information. Any ideas or help would be
grateful.
Thanks

RMI problem with j2sdk1.4

Hi,
I have written a simple Ping program, to exercise me with RMI, this program worked fine with jdk1.3, now I have downloaded j2sdk1.4 and I have installed it, I runned the RMI program but now I have a run-time error message.
Could you explain me what can be happened?
Thanks a lot

The error message + stacktrace would help...
did you also compile with jdk1.4 or just execute with the jre shipped with 1.4?

IllegalAccessError passing object with RMI

Hi,
I am playing with RMI at the moment.
I have a Remote class that implements a Remote interface
The interface has one method which the class implements and this is to get a TestSerial object.
If I run without using a Securitymanager then there are no problems.
When I do use the SecurityManager then there is an error.
This error remains even if set the permissions in the policy file to java.security.AllPermissions
Does anyone know why this is?
thanks in advance,

Problem with RMIClassLoader.loadClass

I am having problem in RMI for SSL. Please reply back.
I have a class which has call to
RMIClassLoader.loadClass( "TestClass");
I am testing with SSL. But it gives ClassNotFoundException for the TestClass even if TestClass is present.
My code
public class loader
public void getInformation()
try
System.setSecurityManager(new RMISecurityManager());
System.setProperty ("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
System.setProperty("java.rmi.server.codebase", "https://localhost:443/ ");
System.setProperty("java.security.policy", "test.policy");
Class c = RMIClassLoader.loadClass( "TestClass");
catch ( ClassNotFoundException e )
e.printStackTrace();
loader class is present in a separate directory than the TestClass. TestClass is present in the root of https://localhost:443/ . It works for http setting on port 80, but not for https on port 443.
test.policy file exists both in the loader directory and TestClass directory.
This is the policy file
grant {
permission java.security.AllPermission;
if i put the TestClass directory in the classpath of loader class it works. But i want loader class to download TestClass from https://localhost:443/ .
Please help.

I am using JDK1.3. Does 1.3 support RMIClassLoader.loadClass()
for SSL?
The stack trace i am getting now
java.lang.ClassNotFoundException: TestClass

Will JDK1.4 help? I will try with JDK1.4.

Remote Delta link setup problem with Bean / Access Service

Hello,
I am trying to setup Remote Delta Link (RDL) between two portals. (Both portals same version - EP 7.0 EHP1 SP 05 - are in the same domain)
I already have the Remote Role Assignment working without any issues.
The following have been done successfully:
1. Same user repository has been setup for both the portals
2. Setup trust between producer and consumer (SSO working fine)
3. Producer added and registered succesfully on consumer
4. Permissions setup on producer and consumer
4. pcd_service user with required UME actions setup
I am able to see all the remote content in the Consumer portal.
When I try to copy the remote content and paste it as local content, I am getting the following error:
Could not create remote delta link to object 'page id'. Could not connect to the remote portal. The remote portal may be down, there may be a network problem, or your connection settings to the remote portal may be configured incorrectly.
After increasing the log severity, I am able to see the following in Default Trace:
com.sap.portal.fpn.transport.Trying to lookup access service (P4-RMI) for connecting to producer 'ess_int' with information: com.sap.portal.fpn.remote.AccessServiceInformation@31c92207[connectionURL=hostname.mycompany.com:50004, shouldUseSSL=false, RemoteName=AccessService]
com.sap.portal.fpn.transport.Unable to lookup access service (P4-RMI) with information: com.sap.portal.fpn.remote.AccessServiceInformation@31c92207[connectionURL=hostname.mycompany.com:50004, shouldUseSSL=false, RemoteName=AccessService]
AbstractAdvancedOperation.handleDirOperationException
[EXCEPTION]
com.sap.portal.pcm.admin.exceptions.DirOperationFailedException: Could not retrieve the bean / access service to connect with producer
Could not retrieve the bean / access service to connect with producer
Like you can see above, there is some bean / access service which is not retrieved successfully. I am not sure if this is a permission problem on the consumer.
I have checked that the P4 ports are configured correctly (standard - not changed) and I am able to telnet from producer to consumer (and vice versa) on the P4 port.
I am stuck at this point and am not able to find any information on this.
I would really appreciate if some one can point me in the right direction.
Thank you for reading.
- Raj

Hi Raj,
Please check your config of the P4 port on the producer. Is it really 50004 (check SystemInfo of the producer)?
I do think there's a problem with the P4 communication since RDL requires P4 connection.
Do you have load balanced consumer-producer connection? Please refer to this blog for further details

Problem with setting oracle type parameter in viewobject query

Hi There,
I am facing a problem with JDev1013. I have a view that has JDBC positional parameters that are supposed to be in parameters for function like:

      NULL,
      ? /* code */,
      NULL,
      TRUNC(SYSDATE),

Problem with IE and pubblishedIntoWall

Hi to all,
   i have a problem with InternetExplorer and CallBack
In my flex code i have :
flash.external.ExternalInterface.addCallback("pubblishedIntoWall", pubblishedIntoWall);
The javascript code:
function pubblishedIntoWallCarrello() {
        document.getElementById("composer").pubblishedIntoWall(1)
In both Firefox and Chrome the javascript works in the right way.
In internet explorer the function pubblishedIntoWall is not called.
Have some one got an idea of this problem?
Thanks for your time

First of all, thank for your reply

Problem with socket permissions!

Hi All!
I'm developing an applet that displays an image after downlading it from a server; this server is different from the server I download the applet from, so I have problems with security. In fact I get the following exception:
java.security.AccessControlException: access denied (java.net.SocketPermission 172.16.1.22:8080 connect,resolve)
I'm using:
- Java Plugin 1.3;
- Netscape 7.0;
- IE 6;
I've tried to self-sign the applet but with no results (maybe I cannot use selfsigned certificate with java plugin 1.3);
After that I've created a new policy file ("MyPolicy" file)and mentioned it into:
C:\Program Files\JavaSoft\JRE\1.3.1_03\lib\security\java.policy
but it didn't resolve my problem (maybe I'm doing something wrong in creating my policy file??!!).
Which steps do I have to follow in order to make my applet connect to images server without security problems?
Thanks so much in advance,
Carlo

1.     Compile the applet
2.     Create a JAR file
3.     Generate Keys
4.     Sign the JAR file
5.     Export the Public Key Certificate
6.     Import the Certificate as a Trusted Certificate
7.     Create the policy file
8.     Run the applet
Susan
Susan bundles the applet executable in a JAR file, signs the JAR file, and exports the public key certificate.
1.     Compile the Applet
In her working directory, Susan uses the javac command to compile the SignedAppletDemo.java class. The output from the javac command is the SignedAppletDemo.class.
javac SignedAppletDemo.java
2.     Make a JAR File
Susan then makes the compiled SignedAppletDemo.class file into a JAR file. The -cvf option to the jar command creates a new archive (c), using verbose mode (v), and specifies the archive file name (f). The archive file name is SignedApplet.jar.
jar cvf SignedApplet.jar SignedAppletDemo.class
3.     Generate Keys
Susan creates a keystore database named susanstore that has an entry for a newly generated public and private key pair with the public key in a certificate. A JAR file is signed with the private key of the creator of the JAR file and the signature is verified by the recipient of the JAR file with the public key in the pair. The certificate is a statement from the owner of the private key that the public key in the pair has a particular value so the person using the public key can be assured the public key is authentic. Public and private keys must already exist in the keystore database before jarsigner can be used to sign or verify the signature on a JAR file.
In her working directory, Susan creates a keystore database and generates the keys:
keytool -genkey -alias signFiles -keystore susanstore -keypass kpi135 -dname "cn=jones" -storepass ab987c
This keytool -genkey command invocation generates a key pair that is identified by the alias signFiles. Subsequent keytool command invocations use this alias and the key password (-keypass kpi135) to access the private key in the generated pair.
The generated key pair is stored in a keystore database called susanstore (-keystore susanstore) in the current directory, and accessed with the susanstore password (-storepass ab987c).
The -dname "cn=jones" option specifies an X.500 Distinguished Name with a commonName (cn) value. X.500 Distinguished Names identify entities for X.509 certificates.
You can view all keytool options and parameters by typing:
keytool -help
4.     Sign the JAR File
JAR Signer is a command line tool for signing and verifying the signature on JAR files. In her working directory, Susan uses jarsigner to make a signed copy of the SignedApplet.jar file.
jarsigner -keystore susanstore -storepass ab987c -keypass kpi135 -signedjar SSignedApplet.jar SignedApplet.jar signFiles
The -storepass ab987c and -keystore susanstore options specify the keystore database and password where the private key for signing the JAR file is stored. The -keypass kpi135 option is the password to the private key, SSignedApplet.jar is the name of the signed JAR file, and signFiles is the alias to the private key. jarsigner extracts the certificate from the keystore whose entry is signFiles and attaches it to the generated signature of the signed JAR file.
5.     Export the Public Key Certificate
The public key certificate is sent with the JAR file to the whoever is going to use the applet. That person uses the certificate to authenticate the signature on the JAR file. To send a certificate, you have to first export it.
The -storepass ab987c and -keystore susanstore options specify the keystore database and password where the private key for signing the JAR file is stored. The -keypass kpi135 option is the password to the private key, SSignedApplet.jar is the name of the signed JAR file, and signFiles is the alias to the private key. jarsigner extracts the certificate from the keystore whose entry is signFiles and attaches it to the generated signature of the signed JAR file.
5: Export the Public Key Certificate
The public key certificate is sent with the JAR file to the whoever is going to use the applet. That person uses the certificate to authenticate the signature on the JAR file. To send a certificate, you have to first export it.
In her working directory, Susan uses keytool to copy the certificate from susanstore to a file named SusanJones.cer as follows:
keytool -export -keystore susanstore -storepass ab987c -alias signFiles -file SusanJones.cer
Ray
Ray receives the JAR file from Susan, imports the certificate, creates a policy file granting the applet access, and runs the applet.
6.     Import Certificate as a Trusted Certificate
Ray has received SSignedApplet.jar and SusanJones.cer from Susan. He puts them in his home directory. Ray must now create a keystore database (raystore) and import the certificate into it. Ray uses keytool in his home directory /home/ray to import the certificate:
keytool -import -alias susan -file SusanJones.cer -keystore raystore -storepass abcdefgh
7.     Create the Policy File
The policy file grants the SSignedApplet.jar file signed by the alias susan permission to create newfile (and no other file) in the user's home directory.
Ray creates the policy file in his home directory using either policytool or an ASCII editor.
keystore "/home/ray/raystore";
// A sample policy file that lets a JavaTM program
// create newfile in user's home directory
// Satya N Dodda
grant SignedBy "susan"
     permission java.security.AllPermission;
8.     Run the Applet in Applet Viewer
Applet Viewer connects to the HTML documents and resources specified in the call to appletviewer, and displays the applet in its own window. To run the example, Ray copies the signed JAR file and HTML file to /home/aURL/public_html and invokes Applet viewer from his home directory as follows:
Html code :
</body>
</html>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
width="600" height="400" align="middle"
codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,1,2">
<PARAM NAME="code" VALUE="SignedAppletDemo.class">
<PARAM NAME="archive" VALUE="SSignedApplet.jar">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
</OBJECT>
</body>
</html>
appletviewer -J-Djava.security.policy=Write.jp
http://aURL.com/SignedApplet.html
Note: Type everything on one line and put a space after Write.jp
The -J-Djava.security.policy=Write.jp option tells Applet Viewer to run the applet referenced in the SignedApplet.html file with the Write.jp policy file.
Note: The Policy file can be stored on a server and specified in the appletviewer invocation as a URL.
9.     Run the Applet in Browser
Download JRE 1.3 from Javasoft
