JRockit - Sun RMI Issue?
Hi All,
I am getting the following error when running a Junit test where I call a method in an EJB in WLS 8.1 SP2 running on Linux using JRockit 1.4.1-05. JUnit is using Sun jvm 1.4.2_05.
Perhaps I should use an older version of the Sun jvm?
Thanks,
-Tony

Error in trying dynamic class loading in sun rmi tutorila
Hi,
I am trying the sun rmi tutorial http://java.sun.com/docs/books/tutorial/rmi/. I am not able to download the stub class from the codebase to client. The server is running in a linux box while the client in a w2k box.
Linux box (server)
==================
web server setting
Alias /rmi_codebase /home/wing/try/java/rmi
rmiregistry setting
unset CLASSPATH
rmiregistry
rmi server
classses
/home/wing/try/java/rmi/client/ComputePi.class
/home/wing/try/java/rmi/client/Pi.class
/home/wing/try/java/rmi/compute/Compute.class
/home/wing/try/java/rmi/compute/Task.class
/home/wing/try/java/rmi/compute/ComputeEngine.class
/home/wing/try/java/rmi/compute/ComputeEngine_Skel.class
/home/wing/try/java/rmi/compute/ComputeEngine_Stub.class
java.policy
grant {
permission java.security.AllPermission;
startup with script as follows
java -cp /home/wing/try/java/rmi -Djava.rmi.server.codebase=http://localhost/rmi_codebase/ -Djava.rmi.server.hostname=man82.air.com.hk -Djava.security.policy=/home/wing/try/java/rmi/java.policy
engine.ComputeEngine
(the server is started happyily)
W2k box (client)
================
class the same as server except removing the stub (ComputeEngine_Stub).
java.policy
grant {
permission java.security.AllPermission;
startup script
java -Djava.rmi.server.codebase=http://man82/rmi_codebase/ -Djava.security.policy=java.policy clientComputePi man82 20
The error encounter is
ComputePi exception: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: engine.ComputeEngine_Stub
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: engine.ComputeEngine_Stub
at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)
at java.rmi.Naming.lookup(Naming.java:83)
at client.ComputePi.main(ComputePi.java:14)
Caused by: java.lang.ClassNotFoundException: engine.ComputeEngine_Stub
at java.net.URLClassLoader$1.run(URLClassLoader.java:198)
at java.security.AccessController.doPrivileged(Native Method)
Is this problem related to codebase setting or security?
BTW, I have tried to put the stub to the client as well, it works.
Thanks in advance of any ideas or input.
WingBased on my previous post, I have performed some more testings of the tutorial code and find that the java.rmi.server.codebase could not be specified in the client side.
Instead, the client follows the codebase set in the server, and thus, the localhost could not used in the server when the client is in separate machine.
This is a bit different from the tutorial, please enlighten me if you have any comments.
To make the dynamic download works,
server side
change the codebase property from http://localhost/rmi-codebase/ to http://man82/rmi_codebase/
client side
remove the codebase property http://man82/rmi_codebase/
It is funny that if I add the codebase property when start up the client, it won't work.
Thanks in advance for any ideas and input.

WLS 6.1 SP2 NSAPI and iPlanet (Sun One) issues
Hi. I am going nuts with this NSAPI issue. I am working in a Solaris 8 environment,
WLS 6.1 SP2 and iPlanet (Sun One)and NSAPI. I can get everything to work fine
and dandy in aniPlanet 4.1 environment. I can not get it to work in an Iplanet
(Sun One) 6.x environment. It appears that some things work differently between
the versions of iPlanet (ie. things contained in magnus.conf and/or obj.conf).
I have tried moving things, removing things, adding things and nothing seems
to work....it's almost as though the NSAPI, etc. are being ignored.
I've attached my magnus.conf and obj.conf files (I cut and pasted them into a
single file so I could upload it). Can anyone help me out here...I've been working
for weeks on this and can't seem to get any answers.
Thanks!
Doug
P.S. For security purpses I changed the first part of the IP add. in the files
to 1234567, etc.
Thanks
[conf_files.txt]Hi Doug
U have to put the following section
Init fn="load-modules" funcs="wl_proxy,wl_init" shlib="./libproxy.so"
Init fn="wl_init"
into magus.conf
and put the rest into obj.conf
Best Regards
Alex

Does anybody know of a good reference document on how to properly install
the NSAPI
plug-in for WLS6.1 & iPlanet6(SunOne) on Unix (Solaris). Many of the references
that
I have been finding are either incomplete, have typo's and are mostly Windows
oriented
(ie. with the .dll's, paths, examples, etc.)
My problem is that our old iPlanet 4.x works fine...everything proxies,
etc. iPlanet
6 just doesn't want to seem to communicate with WLS 6.1 SP2 We tried many
of the
saem things from the 4.x magnus & obj.confs...but things look somewhat different
in iPlanet 6.x (did they move tings..such as the fn's from one to the other,
etc.)
If so..and there are big differences in installing iPlanet 4.x vs. 6.x
then many
of the docs out there are inaccurate. Does anyone know if there is a newer
version
of the NSAPI plug-in for Unix.
I would love to see a basic, working set of magnus.conf obj.conf, MIME,etc
from someone
who has actually gotten NSAPI to work between WLS 6.1 and iPlanet 6 on Unix
(Solaris)
It blows my mind that 4.x works and 6.x doesn't. An updated NSAPI plug-in
, if it exists and perhaps fixes the problem, would make my day. Any ideas?
Thanks!

Jrockit JVM GC issue - weblogic performance and crashes at times
On enabling the verbose gc for memory debug, we have observer the following and we frequently face a JVM issue i.e JVM will be unresponsive due to GC pause and on checking we found the following in GC log.

After consultaion with oracle support team, they have asked to us increase the TLA size and we did as follows but we still see the same message.
tried setting

it was still a problem, tried

Are there any standard tuning recommendations for Jrockit JVM to come over this GC issue? At present, we are using following JAVA options.
-XXlargeObjectLimit:32k -XXminBlockSize:32k -XXtlaSize:min=32k,preferred=64k -verbose:gc -Xverboselog:/tmp/gc.log -Xverbose:memory,gcpause,memdbg,compaction,gc -Xverbosetimestamp -Xgcreport
-RR

RangaIf you want to optimize for pausetime, you can use for example
-Xms512m -Xmx512m -Xns256m -XXkeepAreaRatio:25 -Xgcprio:pausetime -XpauseTarget:200msThe parameters xms and xmx can be adjusted to your wishes. -
How tom invoke an EJB from another EJB using the sun rmi protocl in Weblogi
Hi,
I am particularly new to EJB.
My scenario is
client invoking-->EJB-----invoking ----(Either a webService or an EJB)
in WEBLOGIC
Is it possible that a call from EJB to another EJB or WebService use Sun's RMI as underlying protocol instead of t3 or IIOP which are used in Weblogic ?
Would be really a great help if you could provide me some sample on it on weblogic.Hi Stefan,
You don't need to provide the InitialContextFactory for running a standalone client. The following should work just fine:
Context initial = new InitialContext();
System.out.println("Looking up ...");
Object objref = initial.lookup(EJB); //the lookup name should be a global JNDI name //and not from the java:comp namespace
System.out.println("Looked up EJB");The JNDI implementation looks for the jndi.properties file in your classpath. So make sure that you have the appserv-rt.jar from your <server_installation>/lib directory in your classpath.
HTH,

Hi All,
I have an RMI system, that in command line works perfectly, as expected. However, I have transferred my Client to Servlet and am running it though Tomcat. Now when ever I try and invoke a remote method I receive an error message.
The error is generated as a result of catch statement for the following:
server = (Server)Naming.lookup(fullname);I know the Client code is being evaluated as it generates the HTML error message from the catch. Using a System.out.println and the Tomcat log files I caught the error and wrote it to a log file. It was as follows:
Caught an exception doing name lookup on rmi://localhost/Bank-Server: java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: ServerImpl_Stub (no security manager: RMI class loader disabled)
Caught an exception doing name lookup on rmi://localhost/Bank-Server: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:

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

I have read a little about it and when running the security manager a special command needs to be entered at runtime to invoke the policy? How on earth is this done in a Web application situation?Connection refused: connectIt could be some configuration problem.

Ciscoworks/Sun Solaris issues command
Our Ciscoworks on Solaris always issues commands rusersd to other servers, here is an example to server02, which should not happend. the server itself has nothing to do with ciscoworks.
Can you please tell me why it is issuing this? and how to stop it?
10.Y.Y.101 is the Ciscoworks server,
thanks, Han
Here is one of them: X.X.100.117 Server02
Here are a couple log entries from :

Remote Connection Issue in Oracle JRockit
Hi,
I Tried configuring Jrockit and integrating weblogic server with it.
I was successfull in monitoring the locally deployed app through integrated weblogic in JRMC 4.0.
Please suggest if the following steps mentioned are proper or not.
1) Installed JRMC 4.0 .
2. Configured in default domain/bin folder of Weblogic server setDomainEnv.cmd as follows:-(Configuring oracle Jrockit in Weblogic since i have to use Jrockit JVM instead of Sun JDK Hot Spot)
set BEA_JAVA_HOME=C:\Program Files\Java\jrmc-4.0.0-1.6.0
set SUN_JAVA_HOME=D:\Oracle\Middleware\jdk160_18
if "%JAVA_VENDOR%"=="Oracle" (
set JAVA_HOME=%BEA_JAVA_HOME%
) else (
if "%JAVA_VENDOR%"=="Sun" (
set JAVA_HOME=%SUN_JAVA_HOME%
) else (
set JAVA_VENDOR=Oracle
set JAVA_HOME=C:\Program Files\Java\jrmc-4.0.0-1.6.0
3.Inturn i modified Java_Options in my local weblogic server startWebLogic.cmd and Remote weblogic server startWebLogic.cmd as follows:-
Local weblogic server startWebLogic.cmd :-
set SAVE_JAVA_OPTIONS="-Djava.rmi.server.hostname=ZSLW521 -Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
export JAVA_OPTIONS
Remote weblogic server startWebLogic.cmd :-
set SAVE_JAVA_OPTIONS="-Djava.rmi.server.hostname=ZSLW577 -Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
export JAVA_OPTIONS
4. My Oracle Jrockit Start parameters are as follows:-
C:\Program Files\Java\jrmc-4.0.0-1.6.0\bin>java -Xmanagement:port=7091,ssl=false,authenticate=false,autodiscovery=true
and even i am getting the status as follows in command prompt:
[INFO ][mgmnt ] Remote JMX connector started at address zslw577:7091
[INFO ][mgmnt ] Local JMX connector started
[INFO ][mgmnt ] JDP autodiscovery started at address 232.192.1.212:7095
Iin jrmc4.0 UI i am getting JDP (JRockit Discovered protocal)as follows:-
1. Discovered --> JDP --> zslw577:zsl.local and
zslw51
2.But the Problem is that in the tabbed menu
Discovered-->LOACL-->Getting Local JRockit Weblogic server Instance and Not Remote Server Weblogic Server Instance
is when i am trying to establish a connection :-

RKI had the same problem, but adding:
-Djava.rmi.server.hostname=my_hostname
to the remote WebLogic Server start script that I want to monitor solves the problem.
In my case, my WLS runs on OEL 5, and I monitor it via JRMC (R28.0.0-679) on Windows XP):
# Start JRockit MngSrv to enable JRMC monitoring:
JR_XMNG="-Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
export JR_XMNG
JAVA_OPTIONS="-Djava.rmi.server.hostname=your_hostname ${JAVA_OPTIONS}"
export JAVA_OPTIONS
JAVA_OPTIONS="${JAVA_OPTIONS} ${JR_XMNG}"
export JAVA_OPTIONS

RMI "UnmarshalException" issue
Hi,
I am doing a sample RMI application in the following step by step process but in the *8th* step I am getting exception so please kindly resolve my issue.
Step-1: creating Service interface
AddServiceInterface.java
====================
import java.rmi.*;
public interface AddServiceInterface extends Remote
public int add(int a, int b) throws RemoteException;
Step-2: Compiling Service interface
D:\BAJI\Programs\JAVA\rmi\rmi_server>javac AddServiceInterface.java
D:\BAJI\Programs\JAVA\rmi\rmi_server>
Step-3: creating the Service interface implementation class
AddService.java
============
import java.rmi.*;
import java.rmi.server.*;
public class AddService extends UnicastRemoteObject implements AddServiceInterface
public AddService() throws Exception
public int add(int a, int b) throws RemoteException
return (a+b);
Step-4: Compiling the Service interface implementation class
D:\BAJI\Programs\JAVA\rmi\rmi_server>javac AddService.java
D:\BAJI\Programs\JAVA\rmi\rmi_server>
Step-5: Start the RMI service
1)openned a new command prompt and typed the following command
2)d:\> rmiregistry
Step-6: Create stub and skeleton classes
D:\BAJI\Programs\JAVA\rmi\rmi_server>rmic AddService
D:\BAJI\Programs\JAVA\rmi\rmi_server>
Step-7: Create RMI Server Application which export the Server object into Naming service
RMIServerApp.java
===============
import java.rmi.*;
public class RMIServerApp
public static void main(String[] args) throws Exception
AddServiceInterface asi = new AddService();
Naming.bind("rmi://localhost/as",asi);
System.out.println("\n\n***************** Registored into Naming Service ****************\n\n");
Step-8: Compiling & execute
D:\BAJI\Programs\JAVA\rmi\rmi_server>javac RMIServerApp.java
D:\BAJI\Programs\JAVA\rmi\rmi_server>java RMIServerApp

I am wondering as to why is it trying to connect to a local host 127.0.1.1 instead of the IP Address specified at by"xxx.xx.xx.xx" in the program?
I have the stub class and the service interface classes on my client-side.
Thanks.I am wondering as to why is it trying to connect to a
local host 127.0.1.1 instead of the IP Address
specified at by"xxx.xx.xx.xx" in the program?Because that only specifies where the lookup should be done, i.e. where the Registry is. This lookup() returns a stub to your remote object which has its own IP address and port embedded into it, and that's where 127.0.0.1 is coming from - you're not doing Registry.lookup at this point, you're calling your remote method.
This indicates a DNS or /etc/hosts misconfiguration - your primary IP address is coming up as 127.0.0.1 instead of whatever your public IP address is. Famous Linux issue. You should really fix it in your DNS or /etc/hosts, but you can work around it by setting -Djava.rmi.server.hostname=<public IP address> at the server JVM. -
Every thing works just fine as both the Client and server runs on the same system,, but as i run one of them on a remote m/c,well i am using vmware for that, Client is not able to locate server's stub and server is not able to locate clients classes for dynamic loading..
I am sure its an issue with the way i set the codebase url's but how should i change them.
presently, i set them as
file:/E:/surshikradmin/workspace/rmi-server/bin/ for server..
and kind of same way for client.. should i add the host name too,,but how??? Any help would be highly helpful since its been years i am dealing with issue and solving it will make ma project go rock..
Client side stack trace if it coul help!

RMI-IIOP JNDI lookup returns com.sun.corba.se.internal.iiop.CDRInputStream
I have two different RMI-IIOP java clients, one is working fine and the other is not. Both are using weblogic.jndi.WLInitialContextFactory from wlclient.jar in WLS 8.1sp5 and JDK 1.4.2_6.
One java client is a straight-forward java main. JNDI lookup is returning EJBHome_Stub correctly loaded by sun.rmi.server.LoaderHandler$Loader
The other java client is a complex java program with multiple threads and many jars. A thread does the same JNDI lookup as the simple java client, but the object returned is of type com.sun.corba.se.internal.iiop.CDRInputStream_1_0$1 which has NULL classloader (bootstrap classloader).
What condition triggered the WebLogic InitialContext to default to com.sun.corba.se.internal.iiop.CDRInputStream?Kevin Fung <> writes:
This is usally symptomatic of an IOR without the corresponding stub
being loaded, usually because the correct security manager is not
set. However the client jar bypasses the security manager to try and
avoid this problem, so I am confused as to why you are seeing this. Do
you know which object it is accessing? Can you try putting IIOP stubs
for it in the client?

client.java:9 is:

also, the server side binding is:
-CommandsImpl acct = new CommandsImpl();
-Naming.rebind("rmi://localhost:1099/Thing", acct);
i dunno if i am braindead or if there is something wrong here... i had read elsewhere about delclaring the registry location, if that makes sense... if that is the case, how do i do this?
Thanks in advance!well, here we are again, talking to myself ;)
anyways, i did take your advice and a updated my code... its a little slopyy, as i didn't really go back over it, but it runs and i get that same error... KoQ (the client) cannot run without the ServerCommands.class file being along side it... even if i copy it to the directory, java doesn't like it... the only way it works is if i run KoQ(client) and the server out of the same directory and they share the ServerCommands.class file... its pointless to have to have them both share that same file, because then the server must be the client as well, both running out of that same directory.... ahhhhhhh!
