JBoss3 basic example problem

I started an common example of stateless bean HelloWorld on JBoss 2.4 server and it works,but when I tried to start the identical example on JBoss 3.0 following problem has occurred. During the deploy process there was no any error messages on JBoss console.
Here is console output after running the example:

Hi,
Where is the jboss.jar mentioned?The error is due to unavialibility of the class,the classloader is not able to find(load) the class.So please set jboss.jar,it is avialable at Jboss3.0.2/server/all/lib/jboss.jar.
I used to try this way long back but I found the ant tool to be better utility to work with.Why dont you check the Orielly Workbook at the google and download it.
Regards

About coordinate Mapping Basics example

I revise the coordinate Mapping Basics example,but there are a lot of like sawtooh between the background image and pepople
,i hava a question is there some parameters in K4W V2 SDK can be modified to achieve optimal results?

The samples just provides a rough outline that is generates via the body index frame. There are no parameters to that pipeline as it is the raw data provided by the runtime.
You will need to filter the edges and provide your own blending to the background similar to the v1 backgroundremoval filter. Unfortunately, that sample has not not been ported to v2.

Basic example on Check-boxes using AS3.0 in flash

Hi all,
I need a basic example containing 3 or 5 check-boxes and
should display the names of check-boxes which are
selected in a text-box.
Thanx a lot...

Go to the help subject "CheckBox class" and click "view
examples": The example is an exact answer to your question :-)

Is anybody has the example problem for AD/DA converter controled by PIC16F84?

In my circuit( Multisim 9), I use PIC16F84 as the
MCU to control the DAC and ADC. I want to ask if anyone has the example
problem for the controlling?
Further more, the I/O port of
PIC16F84 seems can not be connected with the digital output of DAC, so
I asked myself, is it right that for PIC16F84, the I/O port can only
connected with the serial port of DAC and ADC? Or it needs a converter
to adapt to the input port of DAC?
Looking for any help! Thanks!

You can test the new Design Circuit Suite (includes Multisim10 with MCU10 and Ultiboard 10 with Ultiroute10). When you open Samples you find the folder MCU with PIC folder. In these you can find some examples to PIC16F84. With that as pattern you should solve the problem.
I attached you here the MCU examples in the *.zip

Really Basic Spry problem

I'm new to CS3. I'm using Dreamweaver, and I want to use the
Spry XML deatail region display. I followed the tutorial for the
Aquo example. When I transfer all of the files to my server, the
spry js effects don't work. No errors, just no function. I checked
the file paths and made sure they matched and that files were in
the right directories on the server. It seems like this must be
something so basic that it's not in the help files. Can anyone
help?

Printing/ printing example problems

i needed to print something in a program i'm writing for a school assignment, so i searched the java site i found a example:
"http://java.sun.com/docs/books/tutorial/2d/printing/example-1dot2/ShapesPrint.java"
i picked the code parts that i needed and tried printing to a file, this didn't work, but no exceptions where thrown, so i tried printing to a different file type (i tried jpg/gif and bmp) non worked, so i tried printing for real, no effect. So i figured i was doing something wrong thus i copied the intire code, the code didn't print jack.
so i tried other examples which where very similar, same fx: no content what so ever, yet the file sizes differd depening on what needed to be drawn, so it did something.
now my question how do i print something?
i would be greatfull if someone would provide me with a working code example which can print to a file/paper

if i'm correct the example prints the contents of a file to a specified file using the dialog.
i copied the example and specified a gif image to be printed, i gave the argument print to file in the dialog.
i also changed
DocFlavor flavor = DocFlavor.INPUT_STREAM.PNG; to
DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF;
now the file dialog give a out.prn file in the textfield, i changed this to out.gif, which didn't work at all. i created a black gif file. without contents and it didn't match the originals file size.
so basically this didn't work.
also this is part of my problem i forgot to specify that i need to print contents of the program (in example a jtable / drawn strings etc, proberly a whole panel). this example doesn;t include that
i really need to get this working, so plz help me out here (btw remove the example from my first post from the java site it doesn't work)

WLS 7.0 JTA Oracle example problem

Hi,
I am trying to get the Weblogic 7.0 JTA, Oracle example working.
This example uses two deployed EJB's and different data sources to
transfer money from one to the other.
The example specifies that one of the database pools should be using
an OCI driver. Unfortunatley I don't have these drivers, and really
only want to use the Oracle JDBC thin drivers. The drive I am using is
oracle.jdbc.xa.client.OracleXADataSource
I have set up two database connection pools, both using XA Java thin
drivers.
Every time I run the example is throws an XA error: XAER_PROTO. I
think this is something to do with the XA transaction not being setup.
Have you been able to get the example to work???
Is there some technique in setting up Oracle XA database pools, and
datasources that I am missing?
I am using Oracle 8.1.7.
Thanks for your help.
Regards.
Andy

Hi!
I'm trying to set up my web application to use client-cert
authentication. I've set in web.xml login config to
<auth-method>CLIENT-CERT</auth-method>. When I'm accessing my
application I'm always getting 401 Unauthorized. If I set
login to BASIC, browser pops up login dialog and everything works
fine.
I've done following:
- created and installed in WLS trusted CA certificate
- created and installed client certificate signed by that CA in

- configured WLS to use ssl and set "Client Certificate Enforced"
- managed to connect to document root or console application

Now I'm really stuck and have no ideas.
Please help. Thanks in advance.

Basic Design Problem: Using an interface as flag

My problem is pretty basic - i just want to know the best way to design that:
Imagine, you have an interface Example. There are two abstract classes implementing this - ExampleOne and ExampleTwo.
Now there may be dozens of classes that subclass one of these two. They provide certain things that may be cacheable or not. By default it should be, but if the class implements NonCacheableExample its results must not be cached.
I tried it by adding an attribute "cacheable = true" to the Example interface and "cacheable = false" to the NonCacheableExample. This doesn't work of course - when i try to retrieve the attribute from whatever class it is always "true", no matter if it implements NonCacheableExample or not. I guess the attribute inherited from the abstract class is "stronger" than the one from the interface.
The only easy way I could imagine would be to add an interface CacheableExample, so that a class needs to implement either Cacheable- or NonCacheableExample - however I'd like it to be cacheable by default.
Puh... I hope that was somehow understandable. Any ideas?

If the abstract class appears "stronger", that's because it's the only one with attributes.

Puh... I hope that was somehow understandable. Any
ideas?You have have a Cacheable interface that includes addToCache() and removeFromCache() methods. The AbstractCacheable implementations of these methods can default to meaningful behavior. The AbstractNonCacheable can implement these methods in such a way that they're no-ops or throw the runtime exception that indicates OperationNotSupported.
Personally, I think this is a bad design. You don't want to build in cacheable or not into an object. If you look at what people are doing with POJO persistence, they go to a great deal of trouble not to have to build persistence into the objects. No marker interfaces like Persistable. I think you should follow this course, too.
Why would something NOT be cacheable? If you have a cache and an object, under what circumstances would you want to absolutely prohibit caching?
Better to stop spending so much time thinking about this and more time thinking about getting a good cache, preferrably not one that you have to write. EHCache and OSCache come to mind. Go get those and get on with it. Neither of them require anything like a Cacheable interface.

HELP me please with a basic Mac Problem

I recently updated to Yosemite, and I have a question that can hopefully be fixed. Even as I am typing, the problem is occuring. The issue is that right now, my cursor is in this little box typing, but all of a sudden, its gone. For example, when you're in Microsoft word or when you're on the internet, and you click on something ELSE, like opening Photo Booth or whatever, the original thing you were on grays out because it is not the primary focus, my macbook is doing that so every few seconds, it removes the "focus" from the internet, or microsoft word, and i have to re-click on the **** thing every few seconds.
another example, I am typing on microsoft word for 2 minutes and the microsoft bar thing is dark gray. without notice, the dark gray turns light gray and now I am getting that little "beep" sound because my cursor is no longer in microsoft word and it stops me from typing anything until i click on word again. any issues why this is happening?

I got a table with 7 columns (parameter:NUMBER).
column1 column2 column3 ...etc.
1 20 3000
0 22 12123
1 24 3244
1 18 4535
1 29 5654
1 40 5775
0 30 2344
0 23 2366
With the procedure (schritt2) above you can calculate the regression function STATS_CROSSTAB(column1,column2,'CHISQ_OBS') with the parameter table_name and two column_names. I get as result:
count(column) age chi_square chi_significance
101 38 38.4 0.002
The problem is that I must repeat the calculation 6 times for 7 columns.
The calculation-code:
OPEN cur_cross FOR 'WITH '
||'att_grp AS '
||'(SELECT '||column1||' as x1 , lev, '||column2||', '
||' CASE'
||' WHEN '||column2||' <= lev '
||' THEN 1 '
||' ELSE 2 '
||'END attribute_group '
||'FROM '||table_in||', '
||'(SELECT level AS lev '
||'FROM dual '
||'WHERE level >= (SELECT MIN('||column2||') FROM '||table_in||') CONNECT BY level <= (SELECT MAX('||column2||') FROM '||table_in||'))) '
||'SELECT count(lev), lev, '
||'ROUND(STATS_CROSSTAB(x1,attribute_group,''CHISQ_OBS''),4)) AS chi_square, '
||'ROUND(STATS_CROSSTAB(x1,attribute_group,''CHISQ_SIG''),4) AS significance, '
||'dense_rank() over (order by ROUND(STATS_CROSSTAB(x1,attribute_group,''CHISQ_OBS'' ),4) DESC) AS rank '
||'FROM att_grp '
||'GROUP BY lev '
||'ORDER BY lev';
Is there a alternative to put this calculation code in a FOR LOOP??

Oracle BPM - Expense Management Example problem

Hi,
I have just started to explore Oracle BPM Version 10.3.2 and I am trying to execute the Expense Management Project as given in the starters documentation.
http://download.oracle.com/docs/cd/E13154_01/bpm/docs65/tutorial/index.html
After deploying the process and going into the workspace using
http://localhost:8585/workspace
I am not getting anything listed in the Applications tab. It is showing the following error:-
Could not retrievePrincipal applications for process '/ExpenseReporting'.
I searched in this same forum and came across this post:-
Re: Why there is no application in workspace?
which says that it may be due to version conflicts or some error coming up in the problems tab.
I checked my problems tab but it is not showing anything.
Eliminating this I thought it may be due to version conflicts (as i am following the post) so I uninstalled all my JDK's and just installed jdk 1.6 update 21 but still I got the same problem - i think this solved the issue for some users (Satya Anareddy)
Then in one comment in the same post given by Dan (Daniel Atwood ) i tried using the default 1.5 JM.
But still I am getting the same error.
I am completely confused as to what the problem could be.
Please could anyone give me some directions.
Thanks,
Rohit

Please follow this step may this solve your problem.
please modify any thing in process "ExpenseReporting" for example any transition or any activity to place some where else or any other modification and then save that process. Then clean the project and build and deploy it.
if this also not solve the problem then export that project to and import it again in your workspace (Create new workspace or change the project name in same workspace ) and then again clean, build and deploy the application then test in work space.

Visual basic code problem

Hello!
I want to use visual basic to build a htm which can control labview throght datasocket, i set the switch
as " Swithc until release " in visual basic, the code is
Private Sub CWButton1_Click()
CWDataSocket1.Data = CWButton1.Value
End Sub
but the led of labview can't light on.
is the code problem?
thanks!

The problem is most likely because you have the code in the Click() event handler. The click event in VB is a left mouse down AND mouse up over the controls. If you are wanting it to send out the value when you press and hold the button down, change the event handler to the ValueChanged event.

Hi,
LabVIEW Example Finder uses NI Service Locator in the background. Try to restart the Service Locator and see if that helps. More information on this can be found at the following link.

JWSDP 2.0 JAX-RPC example problem Fast Infoset

Hi,
I installed JWSDP 2.0 and and Tomcat 5.0 for JWSDP. The server runs fine and the example HelloWorld is accessible (I can see the WSDL file in my browser: http://localhost:8080/jaxrpc-HelloWorld/hello?WSDL).
The Problem is that I can not run the client: I tried "ant run-client". The error occurs while trying to create a stub in the file "HelloClient.java" with the following line of code:
stub = (HelloIF_Stub) (helloWorldService.getHelloIFPort());
This is the error I get:
[java] Exception in thread "main" java.lang.NoClassDefFoundError: org/jvnet/fastinfoset/FastInfosetSource
[java] at hello.HelloWorldService_Impl.getHelloIFPort(HelloWorldService_Impl.java:59)
[java] at hello.HelloClient.setUp(HelloClient.java:68)
[java] at hello.HelloClient.main(HelloClient.java:45)
[java] Java Result: 1
I am not sure about the structure of the application, so I don't know where to look for the "FastInfosetSurce" file.
Thanks for any help.
Best regards.

Hi,
I reselved the problem by just copying the FastInfoset to the jaxrpc\lib directory (I am sure this should work in a different way).
Well, the next problem I am getting is that the "XMLStreamWriter" class cannot be found. This class is contained in jsr173_api.jar.
I guess my main question is the following:
Which projects are necessary to get this simple helloWorld example to work?
I did set the JWSDP_HOME varible. Is there another setting I have to make to have all necessary jar-files available and to be able to run the samples?
Could anybody point me to a tutorial that does not only show a few lines of code (as the HelloWorld sample in the JWSDP-Tutorial) but that would instead lead me through a step-by-step sample application that I write by myself and actually runs at the end? The example in the JWSDP-Tutorial uses all kinds of existing config files which are not explained.
Thanks for your help.

PI Demo Examples problems with executing CTC template for client setup

Dear SAP community,
I use PI 7.30 SP 4 and get the following exception if I use the CTC template to set up the PI demo examples in client 105
and 106
Web Services Configuration
Description
Exception in step "SRT_TECHNICAL_SETUP"
Exception details : java.lang.Exception: BAPIRET2 SRT_ADMIN 050 Could not create service destination
State
Step was skipped
In client 107, the template works after I delete the SAP_WSRT user. In clients 105 and 106, this leads to the exception above,
If the SAP_WSRT user exists, I get the exception that this user alreadz exists if I run the template.
What should I do to fix this problem and properly implement the template on all clients?
PS: I use admin users with SAP_ALL rights. Maybe I use the wrong master password, because I use the one of my SAP_ALL user. This works at least for using the template within client107.
Andreas

Hi Mark,
in my case the workaround of deleting the service user works only in Client 107.
The additional problem with a missing service destination occurs already after deleting the service user in Clients 105 and 106. Will this additional problem also be treated in the new note?
Joerg-Joachim Klossika already added the workaround to this note for the existing service user I proposed to him.
I still cannot resolve the problem with the missing service destination.

Andreas

Please explain Importance of Interfaces ....? [Basic Conceptual Problem..]

Hi everyone..
i am new to java..i want to know the importance of interfaces in java....
interface A{
public void print();
class B implements A{
public void print()
System.out.println("Please explain me the importance of Interfaces");
the class B can also be defined with out interface as the following...
class B {
public void print()
System.out.println("Please explain me the importance of Interfaces");
Both the classes have the same functionality ... then what the use of declaring an Interface and implementing it...?
PLEASE EXPLAIN BASIC USE OF INTERFACES....?
Note: Ignore any syntax errors in the code that i have written above
thanks in advance

In Java, mostly we use inheritance for code reuse.
public class Toy{
public class Ball extends Toy{
}Suppose there is another class Type which doesn't related to Toy family.
public class Tyre{
}Now we know that Ball and Tyre are bouncable. So we will have to implement bounce() method in both class which behave differently.
public class Ball extends Toy{
public void bounce() {
}Suppose there is another class Type which doesn't related to Toy family.
public class Tyre{
public void bounce() {
}*If want to collect bouncable things into a single collection, then how can we do that?*
There is way, we can use abstract class:-
public abstract BouncingThings {
public abstract void bounce();
}Now things that are bouncable can extend BouncingThings class and the collection of bounce things will be
BouncingThings [] bouncingThings;
But there is one problem Java doesn't allow multiple class inheritance. So Ball can't extend both Toy and BouncingThings.
We can use interface:-
public interface Bouncable{
void bounce();
public class Ball extends Toy implements Bouncable{
public void bounce(){
public class Tyre implements Bouncable{
public void bounce(){
Bouncable[] bouncableThings = { new Ball().new Tyre() };Edited by: SandipGaikwad on Oct 16, 2007 12:23 PM
