RuntimeException-LateBound/EarlyBound example
Hi
I have tried to run the late bound and early bound examples,but in the process
when iam running the RunLateBoundSingleMachine.bat
RunEarlyBoundSingleMachine.bat,iam getting a runtime exception with the following
message:
Error Message

Could somebody throw some light if we do require a weblogic license for these
examples to run?
Your help is appreciated.

Hi Damon,
I have the filelist in C:\bea and the directory that is pointing is F:\WebL6.1.Iam
currently running both Jcom bridge and WLS in the same machine.I have written
the same to the support team as well.
Thanks

hi Nandula,
The jCOM runtime is looking for a valid license.bea file. The beahomelist
file
contains the list of directories where it would look for this license
file.
So if
the directory F:\WebL6.1\ is in your beahomelist file and there a valid
license
is located at F:\WebL6.1\license.bea, jCOM will find it.
Are you running the jCOM Bridge on the same machine as your WLS? Currently
jCOM does not support running the jCOM Bridge on a separate machine.
thanks

Hi Damon,
I do have this file under c:\bea.
Well can you tell me if i have to include something in that file ifthe
example
needs to run
Thanks

Hi Damon,
I have a valid license for weblogic 6.1 now.My installation directoryis
in F
drive (F:\WebL6.1\wlserver6.1).Yet iam unable to run this example.Theerror iam
getting is the same.How do we solve this problem?
Thanks

WebLogic jCOM requires a valid 6.1 license in order to run.
what is your WLS installation directory?

Help using jCOM with a WLS6.1 server talking to a COM server instead of an VB/COM client
Hi all,
I successfully ran the BEA's EarlyBound example that has a VB Client talking to
WLS6.1 Server via JIntegra. However, I been unsuccessful in trying to find an
example that has WLS talking to the jCOM bridge to the Wrapper to a COM Server.
How can I use the jCOM/jIntegra tools to reverse the EarlyBound example, if possible,
and have an EJB talk to a "Wrapped" COM Server?To use GPO multitimbrally, first you create a new multi instrument and cable it directly into the audio instrument into which you've loaded GPO. Let's say it's audio instrument #1. The crucial next step is to set audio instrument 1's MIDI channel to ALL (done via the parameters section on the LH side of the screen).
Next, name the multi something like GPO ( LOL ) and click on channels 1 - 8 on that multi-instrument in order to activate them. From this point on, instead of selecting Audio Instrument #1 in your arrange window, you select "GPO" (on whatever channel you want, in this case, 1 - 8).

I am a beginner in learning Weblogic Platform(Weblogic Platform7.0 with sp2),and
now I'm studying the JCOM examples.
Everything goes on well in the examples of "zeroclient" and "latebound",but there's
a problem in "earlybound".
I have succeeded in registering the type library and setting JVM (cmdline:"regtlb
containerManagedTLB.tlb examplesServer"),and I can find "containerManagedTLB"
in References of Visual Basic.
In a word,I think all preparation work is completed.
But there is a fault when it runs at the line "Set mobjHome = objNarrow.narrow(objTemp,
"examples.ejb20.basic.containerManaged.AccountHome")".
=============Let's look at the source code:===================
Dim mobjHome As containerManagedTLB.ExamplesEjb20BasicContainerManagedAccountHome
Dim objTemp As Object
Dim objNarrow As New containerManagedTLB.JCOMHelper
Set objTemp =
CreateObject("examplesServer:jndi:ejb20-containerManaged-AccountHome") -->code
run correctly here
Set mobjHome =
objNarrow.narrow(objTemp, "examples.ejb20.basic.containerManaged.AccountHome")-->this
line is wrong
===============================================================
I don't know where is the problem,and it makes me very painful!

What can be done to make these code examples work on web Browsers?
I have tried numerous versions of ?Hello World? examples over the web to display the text on a web page. All the examples work on my local machine in the application viewer, but they don?t work when from a web browser. I have tried both Firefox and IE.

Exception: java.lang.reflect.InvocationTargetException The latter code is very short and would serve the intended purpose most ideal. It can accept input and allow me to replace the ?System.out.println? function that works so well to display when working with code in the development environment.
Thanks in advance for any input on this.

As per your suggestion, I changed the “extend” to Applet and changed it to “JApplet”. Making that change will result in code that won?t even compile.Right. You're going to have to change your program to actually work as an applet.
Either that or use Java Web Start, which is probably the best option.Thanks. The code I presented was my attempt to find examples that represented the advice I thought I was getting (to use JFrame and JLabels). I?m changing the direction of the examples I?m looking for now.
>
The current code as published by sun.com actually compiles and displays in the Netbeans programming environment. It looks great. But I?m kind of stuck with the missing link for making it output to the browser.Different things work in different ways. You wrote a standalone application which compiles and runs. Writing an applet is a different thing, and works in a different way. Read the applet tutorials for more information on applet methods and the applet lifecycle.Thanks. I?m reading. I try to execute some of the examples from my reading, but and stuck. So, I?m asking for some clarifications of some of the components I?m stuck with. Having some of my questions answered would help me to understand better the lots of reading and studying that I?m doing.
I?m taking in all the advice that is given, and I appreciate it a lot.
>
Thanks for the hints. Thanks also in advance if you happen to know how to change the extend to Applet or JApplet instead of “JFrame” and it works.This is made clear in the applet tutorials. It's more than just changing the class to extend. Note that Applet/JApplet extends Panel/JPanel, so that changes the way your program is constructed. Basically, you don't have to create your own frame.Also, I don?t want a frame. I?m trying to find a way to make my question clear. I appreciate the time you?re taking to respond to a new user?s scope.
>
But again, web start is probably a better choice if you have a running app.
You should probably abandon the idea that you just have to nudge a program slightly in a new direction to make a wholly new thing. Programming is all about reducing complex problems to a set of concrete solutions.Absolutely. I have some examples that will actually print a string to a browser. However, those examples will print what?s written in the immediate code, with no apparent method (that I can) make into a variable. The ?Hello World? example that I find that has a main class is the ones that are failing. The ones that don?t have a main class will print.
I have been trying to find a way to pass a variable to this code that will print over the web:
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;
public class HelloWorld extends JApplet {
//Called when this applet is loaded into the browser.
public void init() {
//Execute a job on the event-dispatching thread; creating this applet's GUI.
try {
SwingUtilities.invokeAndWait(new Runnable() {
public void run() {
JLabel lbl = new JLabel("Hello World");
add(lbl);
} catch (Exception e) {
System.err.println("createGUI didn't complete successfully");
}However when I try to add a functioning main class and change the ?Hello World? to a string variable, it fails. I understand it fails because I?m having a missing link about how to turn the class into something that can take input.
I know I?ll be ridiculed for the example I?m about to print, but I?m printing it to give an example of having a variable for my output.
Look at the code that fails (just to get an idea of what I?m trying to explain):
* To change this template, choose Tools | Templates
* and open the template in the editor.
package test1;
* @author teama
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;
public class HelloWorld extends JApplet {
//Called when this applet is loaded into the browser.
public void init() {
//Execute a job on the event-dispatching thread; creating this applet's GUI.
try {
SwingUtilities.invokeAndWait(new Runnable() {
public void run(String myhello) {
JLabel lbl = new JLabel(myhello);
add(lbl);
} catch (Exception e) {
System.err.println("createGUI didn't complete successfully");
public static void main(String[] args) {
// This is the output of my calculation
// HelloWorld.void("Hello World")
run("My Hello")

SSL/TLS with Anonymous Diffie-Hellman example anywhere?
I'm trying to connect to a server using ssl or tls using TLS_DH_anon_WITH_AES_128_CBC_SHA as my cipher suite, and I'm running into problems (exceptions). Is there an example anywhere showing how this can be done? I have been Googling, and I cannot find something useful.
My code is:
try {
Security.addProvider(new SunJCE());
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, null, null);
SSLSocketFactory sslFact = ctx.getSocketFactory();
SSLSocket socket = (SSLSocket) sslFact.createSocket(getURL()
.getHost(), getURL().getPort());
socket.setEnabledCipherSuites(enabledCipherSuites);
socket.startHandshake();
} catch (Exception e) {
e.printStackTrace();
}and my errors are:
javax.net.ssl.SSLException: java.lang.RuntimeException: Could not generate secret
... (some stuff omitted)
Caused by: java.lang.RuntimeException: Could not generate secret
... (some stuff omitted)
Caused by: java.security.NoSuchAlgorithmException: DiffieHellman KeyFactory not availableAny suggestions, please?Hmmmm ... not a lot of info in the following document from the Safari Development Center, and it's a bit dated too, but just in case it's of any use as a starting point:

Thanks !!I have same problem.
Midi trigger patern correctly. When trying idividual souds, it works but running sequencer do not trigger sound.
HW MacBook Pro (model 2008)
Soudcard: MOTU 828, M-Audio ozonic, internal speaker
Midi: Korg nanoPad, Roland Fantom, m-audio Ozonic,
I invesigate and i found out this:
1)
When open MainStage and automaticaly load Concert, pres midi key - no sound
Then I close just concert not MainStage, open recent concert (same), press midi key - seq playing, soud works
2)
Switch of automatic loading last opened Concert, quit and start MainStage, open Concert manualy and no sound.
Close concert, open again, soud works
3)
Switch automatic concert loading on, open MainStage - no sound
Open preferences, audio / change buffer size, hit applay - sound works
4)
Setup previous buffer size, change routing to buffer
Restart MainStage, no sound, change routing back to output - no sound
Change audio driver to System Setting - sound works - system setting goes to same soundcard
Restart MainStage - no sound
Change system sound output to Internal Speaker - no sound
Change system sound output to soundcard - sound works
5)
Preferences - change audio to System settings, switch off I/O Safety Buffer - below Buffer Size setting
Restart Mainstage - SOUND WORKS
Restart MainStage again - SOUD WORKS -
Errors compiling the rmi-iiop example.
Hello,
I have WebLogic Server 5.1, jdk1.3, Inprise's Visibroker for Java 4.0
and Visibroker for C++ 4.0 all on Windows NT.
I am following the steps on the index.html page in the
examples/rmi_iiop/hello directory in my weblogic directory. The errors
occur at step 5 of the section "Build the client".
The errors are output by the java compiler. They are:
examples\rmi_iiop\hello\_HelloWorld_Stub.java:17:
examples.rmi_iiop.hello._HelloWorld_Stub should be declared abstract; it
does not define bind() in examples.rmiiiop.hello._HelloWorld_Stub
public class HelloWorldStub extends javax.rmi.CORBA.Stub implements
HelloWorld {
^
examples\rmi_iiop\hello\HelloImpl.java:12:
examples.rmi_iiop.hello.HelloImpl should be declared abstract; it does
not define isa(java.lang.String) in examples.rmi_iiop.hello.HelloImpl
public class HelloImpl implements HelloWorld {
Are there issues with jdk1.3? Or have I misapplied some steps?
Any help would be greatly appreciated.
David Hallam
[email protected]The problem you are having is that the compiler is picking up another copy of HelloWorld... see if you can run the compiler with verbose turned on and find where it is getting the interface from... or try using javap...So, here is the output when I compile in verbose mode:

I am running it right now on Fedora Linux.
When I run the demo TPTest.java
as written
ThreadPool thp = new ThreadPool(100);
int count = 10000;
I get and error at the very end of the run like this :

at demo.test.ShutdownHook.run(TPTest.java:14)
Is this correct behaviour?
General this the only error I see. If I start changing the count and Threadpool size to
other combinations, I occasionally get other errors similar to this one as well.

Why not to use static methods - with example
Hi Everyone,
I'd like to continue the below thread about "why not to use static methods"
Why not to use static methods
with a concrete example.
In my small application I need to be able to send keystrokes. (java.awt.Robot class is used for this)
I created the following class for these "operations" with static methods:
public class KeyboardInput {
private static Robot r;
static {
try {
r = new Robot();
} catch (AWTException e) {
throw new RuntimeException(e + "Robot couldn't be initialized.");
public static void wait(int millis){
r.delay(millis);
public static void copy() {
r.keyPress(KeyEvent.VK_CONTROL);
r.keyPress(KeyEvent.VK_C);
r.keyRelease(KeyEvent.VK_C);
r.keyRelease(KeyEvent.VK_CONTROL);
public static void altTab() {
r.keyPress(KeyEvent.VK_ALT);
r.keyPress(KeyEvent.VK_TAB);
r.keyRelease(KeyEvent.VK_TAB);
r.keyRelease(KeyEvent.VK_ALT);
// more methods like paste(), tab(), shiftTab(), rightArrow()
}Do you thinks it is a good solution? How could it be improved? I've seen something about Singleton vs. static methods somewhere. Would it be better to use Singleton?
Thanks for any comments in advance,

I think a singleton might be a better approach for you. Just kill the public constructor and provide a getInstance method to provide lazy initialization.Thanks maheshguruswamy for advising on the steps to create a singleton from this class.
Could you maybe advise also about why do you say that it would be better to use singleton? What's behind it? Thanks!In short, it seems to me that a single instance of your class will be able to coordinate actions across your entire application. So a singleton should be enough.But that doesn't answer why he should prefer a singleton instead over a bunch of static methods. Functionally the two are almost identical. In both cases there's only one "thing" on which to call methods--either a single instance of the class, or the class itself.
To answer the question, the main reason to use a Singleton over a classful of static methods is the same reason the drives a lot of non-static vs. static decisions: Polymorphism.
If you use a Singleton (and and interface), you can do something like this:
KeyboardInput kbi = get_some_instance_of_some_class_that_implements_KeyboardInput_somehow_maybe_from_a_factory();And then whatever is calling KBI's public methods only has to know that it has an implementor of that interface, without caring which concrete class it is, and you can substitute whatever implementation is appropriate in a given context. If you don't need to do that, then the static method approach is probably sufficient.
There are other reasons that may suggest a Singleton--serialization, persistence, use as a JavaBean pop to mind--but they're less common and less compelling in my experience.
And finally, if this thing maintains any state between method calls, although you can handle that with static member variables, it's more in keeping with the OO paradigm to make them non-static fields of an instance of that class. -
Exception running J2EE Kodo car example
on Windows2000, Jboss3.2, running the Kodo J2EE tutorial example When I
add a car to the database (default Hypersonic datasource) I obtain this
exception:
HTTP ERROR: 500 RuntimeException; nested exception is:
com.solarmetric.kodo.runtime.FatalDataStoreException:
java.sql.SQLException: You cannot commit during a managed transaction!
[code=0;state=null] NestedThrowables: java.sql.SQLException: You cannot
commit during a managed transaction!
RequestURI=/sample/Save.jsp
Can you help me?If you are using managed XA transactions, you need to specify a second
connection factory Kodo can use for things like allocating sequence
numbers and other database operations that should not be dependent on the
current global transaction. See the documentation on the various
ConnectionFactory2 settings, and our documentation on XA transactions. -
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...

Eduardo,
These directions worked perfectly, thank-you. One point though, this is
COMPLETELY different to the directions on the index.html page in the
examples directory.

Eduardo Ceballos wrote:
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...

Another question, I used a iplanet web server as a proxy server with a
cluster of two weblogic servers pluged in, although I set
weblogic.properties to round-robin, however, when I run a fibonacci servlet,
it does not do the round-robin. It always go to one machine for a lot of
times. Any idea?
Thank you for your help.

May i presume that your cluster is configured on a shared file system?.
I have seen this problem only if you cluster is configured on different machines
and if the directory structure is not identical.
let us know..

Non-blocking SSLEngine example
Since the example of using SSLEngine with non-blocking IO that comes with Java is quite limited, I have decided to release my own for anyone who wants to see how I solved the various problems that you must face. The example is designed to be a generic non-blocking server that supports SSL.
This is only meant to be an example, as I wrote this mostly in order to learn how to use the SSLEngine, and therefore has certain limitations, and is not thouroughly tested.
You can download the file at: http://members.aol.com/ben77/nio_server2.tar.gz
Here is also the code for SecureIO, which is roughly analagous to the Java example's ChannelIOSecure:
package nio_server2.internalio;
import java.io.IOException;
import java.nio.ByteBuffer;
import java.nio.channels.*;
import java.util.concurrent.*;
import javax.net.ssl.*;
import static javax.net.ssl.SSLEngineResult.HandshakeStatus.*;
* Does IO based on a <code>SocketChannel</code> with all data encrypted using
* SSL.

* SSLTasker is responsible for dealing with all long running tasks required
* by the SSLEngine
* @author ben
private class SSLTasker implements Runnable {

public void run() {
Runnable r;
while ((r = engine.getDelegatedTask()) != null) {
r.run();
if (inNet.position() > 0) {
regnow(); // we may already have read what is needed
try {
System.out.println(":" + engine.getHandshakeStatus());
switch (engine.getHandshakeStatus()) {
case NOT_HANDSHAKING:
break;
case FINISHED:
System.err.println("Detected FINISHED in tasker");
Thread.dumpStack();

} catch (IOException e) {

} catch (IOException ex) {

}That's the reason for checkHandshake(), it is called on every read and write and detects a new handshake and configures the setup properly. As far as the server requesting a new handshake, I did not put that in. It would be simple enough though, you would just need to call SSLEngine.beginHandshake() + then call checkHandshake().
Also, my echo server example had a bug, I forgot to call bu.flip() before queueWrite(), so I fixed that, as well as adding an onConnect method that is called when a connection has been established. The new version should be up at the origional address shortly.
