Identifying EJB3 Application

hi,
how can i differenciate an EJB3 and EJB2 Applications without seeing the source code?
regards,
panneer

Check the version number <ejb-jar> element or check the doctype at the start of the the ejb-jar.xml deployment descriptor. This file is located in the META-INF folder in the EJB's jar. If you have an EAR file, unpack the EJB jar file(s) first.
If there is no ejb-jar.xml file packed with in the jar, assume that you have an EJB3 application.

Build EJB3 application

Hi,
I tried doing a sample ejb3 application by following a step by step process. JSF-EJB3-Glassfish-Netbeans
It ran fine.
But when i tried to import & build the same application in another computer, the BUILD failed:
pre-init:
init-private:
init-userdir:
init-user:
init-project:
do-init:
post-init:
init-check:
init:
deps-jar:
deps-j2ee-archive:
C:\Workspace\sample1\nbproject\build-impl.xml:105: The following error occurred while executing this line:
Target "dist-ear" does not exist in the project "sample1".
BUILD FAILED (total time: 0 seconds)
The build.xml (a snippet) goes as below:
<target depends="init" name="deps-jar" unless="no.deps"/>
<target depends="init" name="deps-j2ee-archive" unless="no.deps">
<ant antfile="${project.sample1-ejb}/build.xml" inheritall="false" target="dist-ear">
<property location="${build.dir}" name="dist.ear.dir"/>
</ant>
<ant antfile="${project.sample1-war}/build.xml" inheritall="false" target="dist-ear">
<property location="${build.dir}" name="dist.ear.dir"/>
</ant>
</target>
The error is at line "<ant antfile="${project.sample1-ejb}/build.xml" inheritall="false" target="dist-ear">"
Has anyone come across this eror? PLease suggest a solution.
Thanks

EJB3 application error

Hello,
My EJB3 application is deployed (as an EAR file) in Oracel AS 10.1.3 on two Solaris boxes. The two environments are supposed to be identical. The application runs as designed in one environment, while throwing the following exception in the other.
Could you help me determine the cause of this error?
Is there a way to see the proxy classes generated by the EJB compiler during deployment?
Thank you,
Michael

I put the interfaces in a separate XX-si-jar file always.
The implementation jar then depends on that service interface jar which gets deployed on both the client and the server.
This way I can distribute my si without including implementation which I can change without needing to affect the clients.Yeah, that seems like the only real solution to me. Using Maven it shouldn't be that hard to manage either now that I think about it. Did you ever get into trouble with a client being based on an outdated interface jar? I can imagine that it can be a bit of a release management drama to keep these things synced.Interface changes when they did happen resulted in full redeployments because the client usually has to change anyway to use the changed functionality. Most interactions are through static interfaces so this doesn't arise too much.
In volatile interactions, a common approach is to define a generic interface EJB whose implementation can delegate the calls to other (potentially future) services. The problem with this is that return types have to be simple.
>
It's one of the reasons why I'm not a fan of optional interfaces in 3.1.Well the optional part is optional ;) To me it is a very useful addition since I usually only deal with local interfaces when I use EJB technology. I always found it a bit of a bother to HAVE to create an interface also, I welcome the change.It is handy to be able to roll out an app with a few classes all bundled in one deployment file if there is no requirement for multiple implementations of an interface or for remote invocation support.
I just feel that it's a lot of flexibility to sacrifice when doing the interfaces is not really a lot of effort with today's development tools.

How to identify which application is deployed wirelessly by BES?

From BlackBerry Manager, can we identify which application is deployed wirelessly by BES, which is deployed by end user himself? thanks.

Thanks, but is a thumb rule that smaller table will be hashed ?
Also, how can i be sure by seeing the executing plan that smaller table is hashed ?

How to identify the application accessing the ESB service?

Hi All,
We have few applications accessing a single service deployed on ESB server.
ESB server is a Linux server with the complete SOA Suite Installation done.
Where on the ESB or the server can we locate or if there are any logs which could help us identify which application is accessing the service.
Any direction on this would be really very helpful.
Thanks & Regards,
Shilpa

Well, you haven't disclosed too much information. How would you like to identify an application? What protocol is in use? Is there any authentication involved? Is it possible for you to send a unique application id with each request on your own?
It all depends on what you have and what you need. In many cases, I would be happy with client IP address in my HTTP access.log ...

Identify the Application Version Cs/Cs2/Cs3???

Hi All,

It's not the endianness inside single bytes (thank the Silicon Gods for that!).[*] It's when you are working with values that require more than a single byte -- i.e., everything above 255 (which is the highest value that can be expressed -- normally -- with a single byte).
Everyone can see that 4589 is less than 9341, even though it has the same number of digits, because, well, the first one's rightmost digit is '9' and the second one's is '1' but that doesn't make sense, because it's the leftmost digit that counts most.
You're thinking, "Sure, but what about that endianness thingy?"
It's the same thing. Suppose you get two 2-byte values:
(a) 123 and 85
(b) 86 and 100
Which 2-byte value is the largest? Well, obviously it's the first one, as the most significant part (123) is clearly larger than that of the other (86). Now suppose you have to design a computer chip, and you have to decide in which order to store 2-byte values. It's quite obvious to you, me, and, for example, Motorola engineers, how you would do that: most significant byte first, then least significant.
Unfortunately, the designers of the most prevalent microchip to date, Intel, decided to do it ... the other way around. (Insert appropriate smiley/sad face/horror here). For some reason, they reckoned it useful to store the least significant part first. Remember, back in "the day" when this was decided, using two bytes to store a number was ... well, how golly big numbers do you computer techies want to process!? Two bytes, that's up in the thousands! Imagine!
So I imagine there must have been a highly technical reason for it.
The term "endianness", by the way, comes from Gulliver's Travels -- which, I'm sure, most of you read. Remember the Civil Wars on which end to start eating an egg?
Applying this to the (a) and (b) numbers, when you are asked "what is the bigger two-byte number?", then you ask "Is it Most Significant Byte first, or Least Significant first?" Is it the former, then it's (a); for the latter, it's (b).
[*] Above-criticized engineers had no problem in deciding that in
10010001
the highest bit value (128) is always on the left, and the lowest (1) is always on the right.

Identify the application server programatically

Hi,
Can anyone help me how to detect that how to programatically identify which application server is being used by my web application?
Thank you in advance.

I want to identify which application server my application is using.I want to do this programatically.so it the server is weblogic, weblogic specific actions can be performed.If the server is websphere, websphere server specific actions i will perform.

Need help identifying the application responsible for an insert...

Hi,
I'm a MSSQL guy and Oracle is still a bit mysterious to me. I'm looking for some assistance tracking down the application in an environment which is responsible for particular inserts.
For example, suppose I have 10 different programs running and inserting values to a DB. I need to know which one of them inserts a "0" in a particular column.
I found a trigger which will tell me the user, unfortunately these programs use a shared credential so that doesn't help me.... here's what I've got:
CREATE OR REPLACE TRIGGER check_for_zero_insert
AFTER INSERT
ON DATA_TABLE_0001
FOR EACH ROW
DECLARE
v_username varchar2(10);
BEGIN
-- Find username of person performing the INSERT into the table
SELECT user INTO v_username
FROM dual;
-- Insert record into audit table
INSERT INTO audit_table
( samplevalue
sampletime,
username )
VALUES
( :sampletime,
:samplevalue
v_username );
END;
But again, username won't help me, I need the originating process if at all possible (either an executable name, PID, or something to identify the specific application on the other side.)

use this in your trigger
select sys_context('USERENV','OS_USER') ||'-' ||user into v_username from dual;
You might need to increase the v_username data type length.
Thanks,

Second transaction in the background in an EJB3 application?

Hi!
Is there any way (preferrably with container-managed persistence, but even manually) to implement 2 transactions in EJB3 that fullfil the following criteria:
a)
pseudo-code:
T1 {
doSomething1
start T2 in background
doSomething2
commit
T2 {
doSomething
commit
b)
conditions: T2 "depends" on T1 in the sense that
1. T2 starts during T1
2. if T1 is rolled back ==> T2 must be rolled back, too
(==> this implies: T2 ends after T1 OR T2 waits for T1 to finish before committing)
3. if T2 is rolled back ==> doesn't cause T1 to rollback
c)
graphically: (intended for viewing with a fixed-width font)
("_" = "commit", "." = waiting)
T1
[ ]---> T2
OR
T1
[ ]---> T2
[_] _The hardest part seems to me to make T2 wait until T1 finishes (in the otherwise unlikely but possible case that T1 finishes first). You can safely presume that the two transactions run on the same JVM, but of course a solution that doesn't rely on this presumption would be even better.
I have tried to find ways for T2 to somehow monitor T1, but on my first half-hearted try I couldn't find anything.
Any ideas?
Thanks,
Agoston

2. if T1 is rolled back ==> T2 must be rolled back, tooI don't think that's possible, the nested transaction is going to be isolated. Otherwise what would be the point of creating it!
The hardest part seems to me to make T2 wait until T1 finishesImplying that T2 is created in a different thread, otherwise T1 would be suspended until T2 finishes in a normal container managed transaction environment. Why thread them when it matters in which order they finish?
I have tried to find ways for T2 to somehow monitor T1, but on my first half-hearted try I couldn't find anythingPerhaps because you've been looking in the context of EJB technology, while you should have been researching 'java concurrency'.

How to identify which application users are connected to in an rdp session

so we have an rdp gateway with couple of servers acting as brokers. users connect to the RD web access site and see a list of applications. usually these applications are the same but with different parameters like (done through the RemoteApp manager)
app1: C:\Program Files\app.exe arg: C:\appdata\group1\file
app2: C:\Program Files\app.exe arg: C:\appdata\group2\file
i'm trying to find a way to tell which app the users are connecting to at a point with no luck, any help will be appreciated
Noor

Hi Noor,
Thank you for posting in Windows Server Forum.
From your description I can understand that you want the user name with app they have in their session.
You can achieve with below command.
Query process User name
Displays information about processes running on a terminal server. You can use this command to find out which programs a specific user is running, and also which users are running a specific program.
More information:

How to identify runnings applications?

Hi,
I like to quit applications before shutdown. Where do I find the listing of runnings applications in 10.8.5?
Thanks

If old eyes are a problem, then here's another way. Press COMMAND-TAB to open the App Switcher. Open apps are displayed and you can switch thru them to shut them down. Or you can use a keyboard shortcut:
Command-Option-Control-Media Eject (⏏)
Quit all applications (after giving you a chance to save changes to open documents), then shut down the computer

Programatically identify the application server vendor

Hi everyone,
We have just passed J2EE certification for an application migrated from WebLogic to NetWeaver 6.40.
Now, we are trying to merge code and resources as much as possible, but there are part of the code where it is just not possible to write generic, and we want to detect what is the type of the application server running.
Is there any simple code to write - like some env/system property to check - which makes it possible to know that we are running on SAP's J2EE engine ?
Any help is appreciated,
Thanks

Hi Vladimir,
Thanks for the proposal, I will try to implement it and see how it is handy.
Actually, the original application is targetted to version 8.1 SP4 of WebLogic app server, which is rather loose on some aspects of the J2EE specifications. Namely it doesn't care when you use non-XA resources, i.e. execute local transactions, when a JTA transaction has already started.
Our application makes use of this "looseness" for performance gain, i.e. some transactions need not be part of the global transaction and makes the system overall faster when executed as local. This also allows flexibility whether we want to privilege performance or data consistency without changing the code.
NetWeaver's J2EE engine, on the contrary, has a strict constraint on this: if a JTA transaction is started, every transactional resource used thereafter must be XA. Conversely, if not JTA transaction was started, then XA resources cannot be used.
As we want to keep the flexibility to use XA or non-XA resources without changing the source code, parts of the code involving JTA transactions and XA/non-XA resources should be switched depending on the app server type.
But I just realized we might as well just test the class of resources involved...
I will give you points after tested your proposal.

EJB3 portable application.

Hi there!
I have to develop a EJB3 application for differents servers (WL, JBoss, Webphere, might GlassFish). I�ve only tested WL and JBoss, and i�ve met with some problems. WL has some problems with local JNDI ( doesn�t work :) and JBoss doesn�s support servlet inyection yet. I think that the JNDI naming convention is different in every server ( i read it�s out of EJB3 specification). Probably i�ll meet more differences.
Do you have any suggestion (link, doc,..) to make a EJB3 application most portable as possible?
Thanks in advance for any help;

First, the font is too small, resulting in a lot of white space on the screen. Unless and otherwise u create ur own bitmap font , u cant make ur system font to be displayed same in all the devices since every device has its own system font.
I was forced to define a command for the OK button. If I did not, my first menu item, was assigned to the Middle Soft Key, instead of the Left Soft Key. On the Samsung, the command does not show up.I came across the same problem .As the softkey code in nokia and samsung differs u get this problem . I will give a snip of code . May it can help u
switch(keycode){
         case LEFT_SOFT_KEY:   // -6 for nokia
         case LEFT_SOFT_KEY: // -21 for motorola
                 now ur code should start here for the left soft key
                 break;This is how i made my application run over all the diff devices

Currently Running Applications - How to identify them.

I'm trying to figure out how I can identify running applications.
I know if I -- for example -- minimize iTunes, I can see the iTunes icon on the end of my Dock. No problem there.
However while exploring I discovered the "Force Quit" menu item and when I clicked it, I could see that Photoshop and a number of other applications was running...but there were not showing up on the Dock.
Is there a way of knowing what applications are running, besides going to "Force Quit."

Hi Dr. Dave;
You might try depressing the control or apple key and "tab" at the same time. That should bring up a bar on your screen with icons for all of the open applications. If you release and depress the "tab" key you should cycle through all of you open applications. Whichever one is selected when you release the keys will be the application you will be in next.
