Simple Java EJB question.

When it comes to EJB v3 Remote and Local interfaces,
(With JBoss EJB Container Software in mind, for this question,)
-Does the Remote interface for the EJB include method signatures from the Bean class
-that are to be seen
-that are to be hidden?
-Does the Local interface for the EJB include method signatures from the Bean class
-that are to be seen
-that are to be hidden?
Which is which for
-EJB 2.1 ?
-EJB 3.x ?
- is EJB 3.x reverse compatible in that it allows use of the javax.ejb.* interfaces,
and would accept a EJB 2.1 approach, or does it force one to use Annotations
exclusively?

Simple Java Coding Question

I know this is a simple question, but I can't search for the answer to this because it involves syntax that Google and the like don't seem to search for..
I am trying to figure out some Java code that I have found. I would like to know what:

My first thought was that they meant to look at the position in the array one less (or more) than i (j). But that doesn't seem to be the case. A is an array of Strings, if that matters...
Thanks for you help.

Plzzz write prog to this simple java threads question

Write a program in C to create four processes. The original processes creates
two children before it prints out "PARENT". The children processes print
"CHILD1" and "CHILD2" respectively. The first child process creates a child
process that prints out "GRANDCHILD".
Note: The output must be guaranteed to print out in the following order each
time it is executed:
GRANDCHILD
CHILD2
CHILD1
PARENT
a. Write the program using C or C++ and forks to create the children processes.
b. Write a second program using Java and Threads for the children processes.
The output statements for CHILD1, CHILD2 and GRANDCHILD must come from print
statements in the run method of the thread.

Most people here will not do your homework for you. If you post a reasonable question that shows you've made some effort, and what the results of that effort were, and provides details about what parts you're having trouble with, then somebody will probably provide guidance so that [you can complete the work.

Simple Java SDK question for server group assignment

I have a snippet of code below in which I am trying to apply the setProcessingServerGroup() and setProcessingServerGroupChoice() methods to my report object. My question should be relatively simple: I believe I need to cast(?) my iObject report object to iProcessingServerGroupInfo per the API in order to use the setProcessingServerGroup() and setProcessingServerGroupChoice() methods, but I'm not sure how to do so.
Can someone please advise how to cast my iObject to iProcessingServerGroupInfo?
Thanks in advance...
Code:
IInfoObject iObject = (IInfoObject) childReports.get(i);
int sgID_view = Integer.parseInt(serverGroupID_view);
int sgPref_view = Integer.parseInt(serverGroupPref_view);
!!!!! CONVERSION / CAST NEEDED HERE !!!!!
iProcessingServerGroupInfo.setProcessingServerGroup(sgID_view);
iProcessingServerGroupInfo.setProcessingServerGroupChoice(sgPref_view);

To followup, I've been able to cast to IShedulingInfo in order to use the setServerGroup() and setServerGroupChoice() methods successfully:
IInfoObject iObject = (IInfoObject) iObjects.get(i);
ISchedulingInfo iSchedulingInfo = iObject.getSchedulingInfo();
iSchedulingInfo.setServerGroup(427);
iSchedulingInfo.setServerGroupChoice(2);
But I don't know how to perform the cast to be able to access the setProcessingServerGroup(), sterProcessingServerGroupChoice() methods.
Any help appreciated.
Thanks!

Simple java architecture question

This should be a simple question to answer but I haven't been able to find a good answer.
I have an application that establishes a network connection with a server and registers event listeners on that connection.
What I want to do is find a way without a busy-wait/while loop to keep the main() thread running so that the listeners can do their job.
Here is a sample of what I've got:
public static void main(String[] args)
SomeConnection conn1 = null;
try
conn1 = new SomeConnection("someaddress");
TrafficManager tm = conn1.getTraffictManager();
TrafficHandler th = tm.createTraffichandler(new MessageListener()
                    public void processMessage(Message message)
                         System.out.println("Received: " + message.toString());
     catch (Exception e)
          e.printStackTrace(System.out);
     conn1.disconnect();
The problem is that the application doesn't stay running to respond to traffic coming across the connection.
Any guidance would be appreciated.
Thanks

Well, what is the job of the MessageListener if it isn't to listen for messages? And apparently it isn't doing that because your application terminates.
Bear in mind that I don't have any idea how any of those four classes work, or even how they are supposed to work. So let me just quote this line from the API documentation of the Thread class which says when your application will terminate:
"All threads that are not daemon threads have died, either by returning from the call to the run method or by throwing an exception that propagates beyond the run method."
That must be the case in your application.

Simple Java Sound Question...

Can I draw waveforms while capturing data? If yes, how. If no, why.
Thanks. I need the answer ASAP, please help.

Hi nfactorial,
Can I draw waveforms while capturing data?If you would like to do that in Java you would need to know about how to use the Java language in general and especially about the Java Sound and Java2D APIs.
If yes, how.It would be too much to explain to answer such a general question. A general answer is, you need to use the Java Sound API to capture the data for which a waveform should be drawn. The Sound API delivers data as a stream of bytes typically encoded in pulse coded modulation (PCM) format. The data stream has digital samples each representing a level of sound pressure for a certain point in time. The stream of samples in the amplitude/time domain need to be transformed to a spectrum of samples in the amplitude/frequency domain, i.e. a number of PCM samples need to be mapped to the frequencies that should be displayed. This is done with the fast fourier transformation algorithm. Each set of amplitude/frequency values can then be displayed as a waveform by using some line drawing logic. The entire process would need to run constantly, i.e. as bytes are received from the sound data stream transformation and drawing is triggered.

Simple Java Array Question

// This is how I was taught to make a simple array. You have to define the size first.
String [] test1 = new String[4];
test1[0] = "1";
test1[1] = "2";
test1[2] = "3";
test1[3] = "4";
out.println(test1[0]);
out.println(test1[1]);
out.println(test1[2]);
out.println(test1[3]);
//If the size is not defined in this second example, why does it still work?
String [] test2 = {"1","2","3","4"};
out.println(test2[0]);
out.println(test2[1]);
out.println(test2[2]);
out.println(test2[3]);
They both produce the same results.

// This is how I was taught to make a simple array.

out.println(test2[2]);
out.println(test2[3]);
They both produce the same results.Umm..the size is just as well defined in your second as in your first...it is a four element array.
The second way is akin to the first...also
String[] s = new String[]{"Hello","I","contain","five","elements"};
System.out.println(s[5]); Will compile..you will get a run-time ArrayIndexOutOfBoundsException (it is a 5 element array, 0-4, but java will not assume that the variable s is not changed between those two lines of code)..
Array index/boundary checking is done at run-time, not compile-time.
In fact:
String[] s;
//let's say up in the program
//and
public void printS(int i)
System.out.println(s);
Will also compile...and if something else happens to set s as a 10 element String array:
printS(9);would work

Simple java pgm - question

Hallo,
to the following pgm I had question:
static void printPrimes (int max) (= wavy bracket;
boolean(should be angular brackets) sieve = new booolean (angular br max+1
angular br)
int i,j;
for (i=2; i = max;i++)sieve(angluarbr i angular br)= true
i= 2
while (i= <= max;) (=wavy bracket Out.println (i+ " "); // is prime
for (j=i; j <= j+i) sieve(angular br j angularb.) = false;
while (i <= maxAmpersandAmpersand !sieve (angular br angular br)I++;
) wavy br ) wavy br.
I hope this is still kind of readable.
Q's are:
after the first "for" there is a new i=2, which seems to staty at 2 all the time; the following while does not change this value ( the beginning for i++ does not change this) and so seems to print 2 at all times (??)
then the inner loop seems to count up all the doubbles of the new prime number and thrwoes it out as false at the end of it;
the i values (increased with i++ seemsto refere at all times to the unit numbers and only indirect to the un it values, which are written/ assigned to it (??)
I seem to wonder how the pgm can print out anythings else the 2's.
I would appreciate any help to that.

I hope this is still kind of readable.No, it's not. http://forum.java.sun.com/help.jspa?sec=formatting
Why are you omitting the braces and brackets? And why don't you type "program"? Aren't we worth the additional time it takes?
Q's are:
after the first "for" there is a new i=2, which
seems to staty at 2 all the time; the following
while does not change this value Why should it? You don't tell it to.
( the beginning for
i++ does not change this)It does. It just gets re-set to 2 after the for loop-
and so seems to print 2 at
all times (??)Yeah. What else?
then the inner loop seems to count up all the
doubbles of the new prime number and thrwoes it out
as false at the end of it; That part is definitely unreadable.

Simple rmi-ejb question

Or you know easier way to make an InitialContext?
Using jndi.properties? But what should it be then??
Please help!
Thanks a lot to alL!!
Best regards, Boris.

well, since you don't specify your app server, how's this?
weblogic.jndi.WLInitialContextFactory
if that doesn't work, try this
com.inprise.j2ee.jndi.CtxFactory
if that doesn't work, try this
com.evermind.server.rmi.RMIInitialContextFactory
if that doesn't work, try this
org.jnp.interfaces.NamingContextFactory
if that doesn't work, try this
com.ibm.websphere.naming.WsnInitialContextFactory
And if that doesn't work, look through your docs again, or maybe try google. Note that whatever you do, you have to have the appropriate jars on your classpath.
Good Luck

Simple Java regex question

I have a file with set of Name:Value pairs
e.g
Action1:fail
Action2:pass
Action3:fred
Using regex package I Want to get value of Name "Action1"
I have tried diff things but I cannot figure out how I can do it. I can find Action1: is present or not but dont know how I can get value associated with it.
I have tried:
Pattern pattern = Pattern.compile("Action1");
CharSequence charSequence = CharSequenceFromFile(fileName); // method retuning charsq from a file
Matcher matcher = pattern.matcher(charSequence);
if(matcher.find()){
int start = matcher.end(0);
System.out.println("matcher.group(0)"+ matcher.group(0));
how I can get value associated with specific tag?
thanks
anmol

read the data from the text file on a line basis and you can do:
String line //get this somehow
String[] keyPair = line.split(":")g
System.out.println(keyPair[0]); //your name
System.out.println(keyPair[1]); //your valueor if you've got the text file in one big string:
String pattern = "(\\a*):(\\a*)$"; //{alpha}:{alpha}newline //?
//then
//do some things with match objects
//look in the API at java.util.regex

Problem with getNodeValue() - simple Java XPath question

I am trying to extract the node values from a XML file:
<root>

     <boxes>
       <box>
          <spec>22</spec>
          <spec>2222</spec>
       </box>
       <box>
          <spec id="BA" value="short"/>
          <spec id="BB" value="thin"/>
          <spec id="BC" value="black"/>
          <spec id="BD" value="full"/>
          <spec id="BE" value="7"/>
          <spec id="BF" value="deactive"/>
       </box>
     </boxes>
     <circles>
       <circle id="CA" value="blue"/>
       <circle id="CB" value="green"/>
     </circles>
</frame>
</root>I use this code:
         XPathFactory factory = XPathFactory.newInstance();
         XPath xpath = factory.newXPath();
         XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec");
         Object result = xPathExpression.evaluate(doc, XPathConstants.NODESET);
         NodeList nodes = (NodeList) result;
         for (int i = 0; i < nodes.getLength(); i++) {
             System.out.println(nodes.item(i).getNodeValue());
         }But only:
null
null
null
null
null
null
null
null
get printed. I would have assumed:
22
2222
null
null
null
null
null
null
since the two first spec nodes contains the above numbers. Any ideas?

change this:
XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec");to this:
XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec/text()");Need to xpath all the way down to the text of the node.
You could use
System.out.println(nodes.item(i).getTextContent());with your current xpath but if the spec node has children, these will also be included in the output.

Efficiency Question: Simple Java DC vs Used WD Component

Hello guys,
The scenario is - I want to call a function that returns a FileInputStream object so I can process it on my WD view. I can think of two approaches - one is to simply write a simple Java DC that does so and just use it as a used DC so I can call the functionality from there. Or create another WD DC that exposes the value (as binary) via component interface.
I'm leaning on the simple Java DC approach - its easier to create. But I'm just curious on what would be the Pro-side (if there's any) if I use the WD Component interface approach? Is there a plus for the efficiency? (Though I doubt) Or is it just a 'best/recommended practice' approach?
Thanks!
Regards,
Jan

Hi Jan
>one is to simply write a simple Java DC that does so and just use it as a used DC so I can call the functionality from there
Implemented Java API for the purpose mentioned in your question is the right way, I think. The Java API can be even located in the same WebDynpro DC as your WebDynpro components. There is not strongly necessity to put it into separate Java DC.
>Or create another WD DC that exposes the value (as binary) via component interface
You should not do this because in general WD components' purpose is UI, not API. Implementing WD component without any UI, but with some component interface has very-very restricted use cases. Such WD component shall only be a choice in the cases when the API is WebDynpro based and if you have to strongly use WebDynpro Runtime API in order to implement your own API.
If your API does not require WebDynpro Runtime API invocations or anything else related to WebDynpro then your choice is simple Java API.
>But I'm just curious on what would be the Pro-side (if there's any) if I use the WD Component interface approach? Is there a plus for the efficiency?
No. Performance will be better in simple Java API then in WebDynpro component interface. The reason is the API will not pass thought heavy WebDynpro engine.

Creating a simple java client for a session EJB local interface

Hi all
Is it possible to create a simple java client for a session ejb local interface with JDeveloper.
The problem is that it creates a test client for a remote interface only...
i.e.
MySessionEJB sessionEJB = context.lookup("MySessionEJB")
and once i try to adjust it manually for the local interface...
MySessionEJBLocal sessionEJB = (MySessionEJBLocal) context.lookup("MySessionEJBLocal") (MySessionEJBLocal - is the name of my local interface)
it generates the exception:
javax.naming.NotFoundException: SessionEJBLocal not found
at...........................(RMIClientContext.java:52)
There is still no problem with accessing the local interface object from the jsf project where i've added <ejb-local-ref> tag into the web.xml file.
but i need the possibility of testing the simple java client for the local interface to test business methods wich should return objects without indirect properties
Thanks in advance.
Alex.

Pedja thanks for reply.
I still dont understand what is wrong with my example.
The first peace of the code i wrote (getting the reference to the remote interface object) works pretty well, and even more it is produced automatically by JDeveloper, so why we cant get a reference to the local interface object the same way?
Certanly we should use the local interface for getting access to the resource functioning under the same local jvm and i think it doesnt metter wich app server we really use wls or oas or others
Thanks. Alex.

How to update the file in simple java archive file on Netweaver2004s

We have a J2EE application containing few properties file packed inside a java archive. These properties are Configuration properties which we are required to change few times after deployment.We are using SAP Visual Administrator to deploy\undeploy our application.We found out that Visual Administrator dose not support update of files packed in a simple Java Archive in Single File Update Option. It only allows updates of EJB Modules archive.
Please let us know if there is any other way we can update a file inside a simple java archive.

Well, Thanks for the help but,. i didn't understand
try not opening the file every time. As I only know that I need to open a file if i would like to update the records..
The update is not happening :
Firstly it shows like this (new.txt):

Can we call a simple java application from ESB

Please let me know how this can be done by using a ESB. The application jar exists on the host server. How we can pass parameters etc and receive results from this application.
Any help will be greatly appreciated.
Prakash

Not sure if I completely understand your question, but you can certainly try following ways:
- call your java application via WSIF. ESB with JAVA wsif is available in 10.1.3.3.1 only (it is not supported in 10.1.3.3 very well).
- you will have to include this jar file in server.xml or bpel/system/classes so that it is available to the SOA jvm.
- You mentioned it is simple java application, but if your java API has complex (object) input and output, you will need some work
