WL6.1 GA- IIOP examples question

Hi,
I have a couple of questions about the WL6.1GA - IIOP example. First when attempting
to build the example, the ant script halts with the following error:
compile_client:
Unable to create client.idl.
BUILD FAILED
E:\bea\wlserver6.1>>\samples\examples\iiop\ejb\stateless\cppclient\build.xml:41:null
On a closer look at the build.xml, the halt occurs with the WL defined ant class:"weblogic.ant.taskdefs.iiop.CppIdlSetup"
My first question, has anybody else been able to build the example as supplied
? Is there any massaging required ?
As I understand it, the previous step in the build (ejbc) generates the required
idl interfaces (Trader.idl, TradeResult.idl, TraderHome.idl) for accessing the
ejb.
So I'm very curious in seeing what the WL defined ant task is doing and defining
for ant generated idl (client.idl). Is the src for the WL defined ant task available
anywhere ?
Thanks in advance.

Hi Andy,
The env. vars were set. Thanks for the
explanation, I was curious as to the latter :)

fixed just before release. I will check. Did you set the examples
environment before running ant?>

idl interfaces (Trader.idl, TradeResult.idl, TraderHome.idl) for accessingthe
ejb.Correct, but bugs in Visibroker make it necessary to pre-parse the idl
into a single file. Inprise have confirmed this as a defect and may
fix this for the next release of Visibroker at the end of the year.
So I'm very curious in seeing what the WL defined ant task is doingand defining
for ant generated idl (client.idl). Is the src for the WL defined anttask available
anywhere ?All it does is pre-process the idl, e.g. cl -E -Iidl TraderHome.idl >
client.idl.

Build process for ejb iiop example

Hello and thank you in advance,
I'm trying to build the examples under iiop examples for WL6.1 (Win NT), and the
'ant' build xml file contains a tag line <createidl ... which causes the build
to fail. I've been unable to find anything on this tag.
Am I supposed to replace this line with some other code? If so, then can anyone
help with the code.
Thanks!

OCA example questions on Oracle website

May I ask those with more experience -- the sample OCA exam questions on the Oracle website (not any purchased practice test, just the 8 example questions) seem more devilish to me than any training materials or books I have read. The code is unformatted and unindented, deliberately tricky, static blocks popping up willy-nilly outside of methods and such, and for every question you just have to hack it out line by line. Whereas on practice tests I am scoring well, I got most of these samples wrong at first pass. There's not a single sample question there that's anything like the simple multiple choices I am getting in practice exams about basic concepts such as what is inheritance, what are interfaces, what is an abstract class, etc. etc. I guess my question is -- should I really be getting ready for 90 scary code-deciphering questions, even though my training materials reassure me I am doing just peachy? [I am keenly worried, by the way, about this question making it look like I don't like digging into troublesome code or that I am whining that it is "too hard."]
P.S. I am such a newbie I guess that I don't know basic things, but I am curious as to what the term "brain dump" means -- I have read on the forum that it is a form of cheating. I infer that it is basically training for exams by using quickie cheat-sheets instead of truly absorbing and knowing the material? Is that the definition? Why in heck would somebody want to get a certification that way if they couldn't actually do the work?
Best wishes to all.

Best wishes to all.I sometimes refer, somewhat cynically as is my way, to the 8 or so samples questions as the 'beta rejects' ... questions that were tried on the beta exam but rejected for the production exam. From my memory (perhaps a little poor) some are less than perfect.

DB Insert Example question

I want to insert data into a SQL database using the Insert Example.vi, as a base for my code. I have to add a large number of parameters to the database. My questions:
Is there a limit to the number of parammeters I can add?
I noticed that the example added two parameters (Device name and number of samples) It then uses "DB tools free object.vi" two times. Do I have to call the "DB tools....vi" once for every parameter I send?
thanks
Bob

There is no "limit" to the amount of fields that you can pass through an ODBC to SQL other than your connection timing out if it is EXTREMELYYYYY large.... I would guess that for all practical purposes you would not reach this point.
You can use the Insert Data vi which you would just have to specify the table name that you want to insert. Keep in mid that if you use this functiuon, you need to insert a cluster with THE SAME exact amount of fields as your table in the database. You would use this function if you want to insert a value to every single field in the database. If you dont, then you would use the Execute SQL Query vi, which you would wire a string with your query which in this case would be an INSERT statement.
I hope this helps.

XSQL SVG Example questions

The SVG example provided with the XSQL servlet is excellent and illustrates at least 5 different (and very useful) techniques. Congrats to whoever came up with it.
This one example shows SVG, named templates, use of xsl:variable, use of xsl_param, use of xsl:with-param, use of xsl:call-template and the apparent use of java classes from a jar file ala java server pages.
The example also raises several questions:
1. The example uses two namespace declarations I haven't seen before -
xmlns:Color="http://www.oracle.com/XSL/Transform/java/java.awt.Color"
and
xmlns:Integer="http://www.oracle.com/XSL/Transform/java/java.lang.Integer"
These appear to be allowing the use of Java classes in some jar file similar to the way Java server pages might do it.
It this correct? Is this because these two classes were built-in to the XSQL servlet? What other classes can be used? All of them? From any jar file? Is more documentation available?
2. What does the 'doctype=system="svg-19990812.dtd"' line do? There is no such DTD on my system but the demo works fine. There are references to DTDs with similar names in the FOP samples and in Adobe's samples but the name is slightly different.
3. Why is the media-type image/svg? The SVG 1.0 spec dated 2 Nov 2000 in section 1.2 says the SVG mime type is "image/svg+xml".
4. Why is there no namespace declaration for the svg tag or any of the svg related tags? Samples from other vendors seem to always have a declaration.
Thanks again for a great piece of code.

Rick,
You'll find a further-refined, and fully-explained version of the SVG example in Chapter 16 of Building Oracle XML Applications. This chapter covers the use of XSLT extension functions and illustrates how to use Java extension functions with the Oracle XSLT engine.
[list=1]
[*]The two namespaces you list are the way that the Oracle XSLT engine allows you to map extension functions in a namespace to methods of a Java class. This example illustrates using two different built-in classes of the JDK, java.awt.Color and java.lang.Integer. These are not specific to (or built-in in any way to the) XSQL processor or the XSLT engine, but are base classes in the JDK. You can use any Java extension functions in your XSLT stylesheets. The only requirement is that you (1) get the namespace correct to assign a namespace to the appropriate fully-qualified classname, and (2) make sure the classes you want to use are in the CLASSPATH.
[*]The <xsl:output> attribute doctype-system provides a value to be used for the SYSTEM URI of the <!DOCTYPE in the transformed output. The particular value was required by the SVG draft at the time I built the demo. It must be handled by a special entity-resolver built into the SVG Viewer that you're using, which explains why not having on your system as a physical file doesn't stop the demo from working.
[*]The media-type is image/svg instead of image/svg+xml because the SVG demo was built before the final draft of SVG went out. This value was apparently changed in one of the final drafts. It appears that the Adobe SVG viewer registers itself as the handler for both.
[*]See http://www.w3.org/TR/SVG/struct.html#NewDocument. The spec appears to allow both unqualified use of <svg> as well as namespace-qualified <svg:svg> when SVG is embedded within another document.

RMI-IIOP Example for Java SE 6

Hi.
Can someone provide me an example (link or code) of how to write an RMI-IIOP remote object, bind it to jndi (glassfish) and then call it from within the glassfish application server (I'm calling from an EJB).
The guide available at http://java.sun.com/javase/6/docs/technotes/guides/rmi-iiop/tutorial.html is unfortunately not helpful because it the code there does not work when binding the remote object in glassfish JNDI (using empty InitialContext constructor) as opposed to the orbd daemon that is described in the guide.
Am I not allowed to bind RMI-IIOP objects in glassfish application server JNDI, i.e. do I have to use orbd?
Do you have to generate stubs for the remote objects in Java SE6? The tutorial says to do it but the exception I get on glassfish application server is not from the _<interface-name>Stub.java but rather from <interface-name>_DynamicStub.java.
Any help is greatly appreciated!

Are you trying to create an RMI-IIOP server inside an
Application Server (Glassfish)?I'm not really sure about how it all works but I don't think so. I am exporting my Remote objects (using PortableRemoteObject) from a standalone Java SE client app. Relating this to normal RMI I had assumed that this automatically started an RMI-IIOP server on an anonomous port, although I now see that the javadoc says that the export method only "Makes a server object ready to receive remote calls.", whatever that means. So if calling the export method doesn't start an RMI-IIOP server then I'm guessing I would have to start one, and then yes, if possible, I would like to do it in glassfish and avoid starting up more applications.
I am guessing I am missing something fundamental here..
The tutorial uses the JNDI Registry (tnameserv). (and
it works fine)Is that what is automatically started when glassfish application server is started?
Have you looked into using a Portable Object Adapter?No, I have not. I want to keep it as simple and close to regular RMI though, so if possible I would like to avoid POA.

Old Producer/Consumer Example question

how would I take this code, the old producer/consumer example, and make it for 2 consumers and 1 producer?
basically, like this:
Producer put 1
Consumer #1 got 1
Consumer #2 got 1
Producer put 2
Consumer #1 got 2
Consumer #2 got 2
etc.....
***********Producer.java***************
public class Producer extends Thread {
private CubbyHole cubbyhole;
private int number;
public Producer(CubbyHole c, int number) {
cubbyhole = c;
this.number = number;
public void run() {
for (int i = 0; i < 10; i++) {
cubbyhole.put(i);
System.out.println("Producer #" + this.number
+ " put: " + i);
try {
sleep((int)(Math.random() * 100));
} catch (InterruptedException e) { }
***********Consumer.java***********
public class Consumer extends Thread {
private CubbyHole cubbyhole;
private int number;
public Consumer(CubbyHole c, int number) {
cubbyhole = c;
this.number = number;
public void run() {
int value = 0;
for (int i = 0; i < 10; i++) {
value = cubbyhole.get();
System.out.println("Consumer #" + this.number
+ " got: " + value);
***********CubbyHole.java***********
public class CubbyHole {
private int contents;
private boolean available = false;
public synchronized int get() {
while (available == false) {
try {
wait();
} catch (InterruptedException e) { }
available = false;
notifyAll();
return contents;
public synchronized void put(int value) {
while (available == true) {
try {
wait();
} catch (InterruptedException e) { }
contents = value;
available = true;
notifyAll();
***********ProducerConsumerTest.java***********
public class ProducerConsumerTest {
public static void main(String[] args) {
CubbyHole c = new CubbyHole();
Producer p1 = new Producer(c, 1);
Consumer c1 = new Consumer(c, 1);
p1.start();
c1.start();

instantiate another consumer.
public class ProducerConsumerTest {
public static void main(String[] args) {
CubbyHole c = new CubbyHole();
Producer p1 = new Producer(c, 1);
Consumer c1 = new Consumer(c, 1);
Consumer c2 = new Consumer(c, 2);
p1.start();
c1.start();
c2.start();
but then modify CubbyHole so that it checks that it has been consumed twice (as thats what you want, you said). Instead of using boolean available, use an integer flag that counts how many times its been consumed, and then reset the flag when it gets to 2. Something like that. Is this a college question? Do your homework. ha ha.

Java Proxies Inside Story Example: questions

Hi,
I've tried to implement the example of the document "Java Proxies and SAP XI - The Inside Story, Part II". Actually it's not running and I don't know why. Maybe anybody of you already implemented the described scenario successfully and can support me here:
InvokeProxy.jsp
- in the first code line, why is is import="http2Db.ProxyCall"? When I have a look at the coding, I think it should be import="http2Db.InvokeProxy"?
I've created the EAR project and deployed it to the J2EE Engine. When I try to test the scenario invoking the JSP side I just get back "The page cannot be displayed", the normal browser exception message. How can I check what goes wrong? Here I'm wondering that the Send Button of the HTML form in the JSP page invokes the function proxyfun(). That function itself has the following codeline within:
document.frm_proxy.action="ProxySender.jsp"
What's that for a jsp page? I cannot find it in the "Java Proxies[...].pdf"?
BR
Dennis

up
Has nobody tried this scenario before? Cannot imagine as it's always mentioned when there's a question concerning java proxy implementations as a reference
I mean the following documents:
https://sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/f272165e-0401-0010-b4a1-e7eb8903501d

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...

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...

Bluetooth simple client example question

Dear all,
I am not sure whether I am close to make it. I update my bluetooth driver {http://forums.ni.com/ni/board/message?board.id=170&message.id=301780#M301780}, so it seem the labview (simple bluetooth server example) can work with my bluetooth (please read the first picture). However, the error message comes up when I run the simple client program. I have a question. Do I have to make the client and the server program in two computer?
I need your help
Thanks

Just want to make a couple things clear
1. my bluetooth device is working well, after I remove dell driver and using XP bluetooth stack <-----I think
2. I can run the server without no problem, the problem comes from the client part.
I have attached the pic from the device manager
Please help, failure will lose my job

Need help with problem using sound and vibration examples. question repost

I am generating a wav file using the sound and vibration example vi "SVXMPL_Wav Recorder(DAQmx)" using a ni 7422 board. Then, using the example vi SVXMPL_Getting started with SVT(Simulated)" attempting to play back that file. the wav file will load and play back on the graphs fine but when I click the "Play Wav File" which sends the audio to the computers speaker, I get the error "Cannot recognise sound Format". It plays the shipped example files fine. I can also play the wav files I generate on a Windows audio player. Don't know a lot about the sound and vibration toolkit or wav file formats but need to get these two to work together. Using LV 8.5 and sound and vibration toolkit 4.0. This is a bit of a repost of the same question ask last week but not answered. Thanks

Did you see Coq Rouge's reply in your original thread? Which thread are you going to continue?

Query by example questions

I have a couple questions. I have been using query by example and I really like it. What I want to do though I haven't seen, and i am new enough to toplink that i dont know the best way to do it.
Say I have a table t with 1 column (name : varchar2)
What I want to do is a query on name using the like operator (I know how to do this), what I dont know how to do is tell it to ignore case. So for example
select * from t where upper(name) like 'BU%'; something to this effect.
Any help greatly appreciated. If I cant do this with query by example which query method would you suggest?

If you use a QueryByExamplePolicy, you should be able to specify to use likeIgnoreCase for String.
i.e.
queryByExamplePolicy.addSpecialOperation(String.class, "likeIgnoreCase");
If you were using the Expression API this would be,
builder.get("name").toUpperCase().like("BU%");
or,
builder.get("name").likeIgnoreCase("BU%");

Scroll bar on clusters example - question

Hello,
I know there are allot of toppics about this subject but I found an example that would do the trick for me.
But it won't work. I can scroll but nothing happens...
I'll post the original example i found and an example to show you how i'm using it.
My cluster contains a boolean 2D array and a nummeric 1D array.
It is not the actual data but the setup is the same.
kind regards,

i'm affraid I did something wrong again
I think it could be a solution but it won't fill up.
I'll send you the original VI i'm working on.
You won't be able to run it though 'cause i'm using hardware.
I kept the original layout too so you could see what the idea actually was. But yours is an option too.
thanks for your time and effort!

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.

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:

Spry Examples - Question

I'm not sure this is the case but it seems to me there are
many more examples referenced than on the "samples" page??
I would like to propose (if not already asked) that we have
an area that all the Spry examples + some good users examples
posted with a small description on one page or location. Others may
have other ideas as well... It just makes it easier than searching
through the slow forum here.... :o)
Thanks, Matt M
