Use of ThreadLocal in EJB to store Transaction id

Hi ,
I my application we need to retain the transaction id for logging . We had a facade layer which are stateless session beans . We use an EJB interceptor to get the transaction id from the request object and put it in a threadlocal . We retrive the transaction id when we log . We have done some POC and it works well .
In some cases we have call to local ejbs to demarcate the transaction boundary , for the local ebjs we call the other helper classes . Just wanted to know if the transaction id can still be retrieved from the helper classes . Any help would be highly appreciated .
Thanks,
Tirthankar

Hello Roberto,
1) Yes, but we anticipated this performance issue by switching to an external Content Server. I also remember one performance issue: when you are uploading an attachement in your session, the system will store it in a temporary table BBP_TRANSCONTENT (the content is not stored in memory). It will be definitively stored in BBPCONT only if the user saves the purchasing document (otherwise we pollute the final table).
2) You have to "migrate" old documents from BBPCONT to the new Content Repository (ex:Content Server). There is a report for that : RSIRPIRL.

You need to use a CallableStatement for this.

Can I use static variable in EJB?

Many books suggest developer don't use static variable in EJB,I want to know why?
I know there isn't any problem if the static varibale is read only
For writable static varible ,what will happen if I use a static Hashtable for share data
Help me!Thank you very much!!

Greetings,
I know that "EJB business methods are not allowed to
block on synchronized resources" Just where do you "know" that from?? The EJB 2.0 Specification, at least, is nowhere in agrement with this statement. If it comes from a book I would question the author's reasoning. Contractually, there's no sound basis for this. In the case of Session Beans, they have an expressedly direct and single-threaded association with a client. From a design viewpoint, it certainly seems unnecessary for a bean to "block" its one-and-only client, but to say that it "is not allowed to" do so is without merit. Entity Beans, on the other hand, are concurrently accessible. Yet, with regard to a transactional context being in effect, the container does indeed block on a bean's business methods. For the bean to do so itself is, therefore, unnecessary. Furthermore, the specification explicitly concedes that a "Bean Provider is typically an application domain expert" and "is not required to be an expert at system-level programming." (EJB 2.0 Spec. 3.1.1) From these statements alone it is reasonable to assume the above statement is meritless since the Bean Provider is not expected to even consider synchronization issues when developing a bean.
But I'm mixed up why we could use "Hashtable" or otherApparently, because your sources are as well...
collection classes in the EJB ,in these method many
methods are synchronized In fact, not only "can we use" them but, with respect to multiple-row finders in Entity Beans we are [i]required to use them (or an iteration of them)! Not all Collection classes are synchronized (so called "heavy-weight collections"). As shown above, that the choice of a particular Collection class might be synchronized is of little consequence since a bean designed under strict adherence to the specification ensures that it is never concurrently writeable.
Could someone provide a good way for this problem?
Please Help Me!!!Regards,

Why use app server and EJB?

we have a project about Component-based Library for Business Information Systems.
We have chosen Point-Of-Sales System as the type of our system.
why do we need to use app server and EJB?
Hope can have replies soon. Thanks so much!
regards
beginning of EJB

Well, you don't need to. You might want to because transaction management is important for point-of-sales and app server/EJB gives you that for 'almost nothing'.

Using a variable in SQL to store intermediate results

I'm new to Crystal Reports, so pardon my ignorance.
I need to write a SQL statement in Crystal Reports (Ver. 11) that uses results from a query and stores them in a variable for further use in the statement. Something like this:
DECLARE @my_variable INT;
SET @my_variable=
CASE
                WHEN DATEPART (m,{?Date})<7
                THEN DATEPART (yyyy,( DATEADD (year,-1, {?Date})))
                ELSE DATEPART (yyyy,( DATEADD (year,0, {?Date})))
END
(Where {?Date} is a date parameter)
Is it possible to achieve this in the above form or some other form in Crystal Reports?
Thanks

Simple answer... When I used the variable, I marked it as a string. There is an email address setting.

Using JarSettings to generate EJB client jar, but supported classes missed

Appreciated for any comments in advance.
I am using @jarSetting to generate EJB client jar file from workshop 9.2. The remote method of EJB has one input parameter that is defined as an interface. The interface is included in client jar, but the implementation of this interface is not.
Please advise how I can add the implementation of this interface to client jar?
Best Regards,
James

Hi James,
I believe the algorithm for creating the client jar is to simply inspect the EJB interfaces using reflection and to include all user defined classes and exceptions that are referenced by the interfaces. In your case, it sounds like a class is not being included because it is not directly referenced by one of the EJB interfaces.
I think the client jar creation algorithm can be described as "best effort" and unfortunately, it does not always end up including all classes needed by the client. I would recommend you add the additional classes manually using the jar tool.

I cannot figure out how to set my apple id to use: itunes (two of accounts), apps store and itunes store. How do I make one password that will be recognized by all these devices? My apple id is constantly not working.

Hi Lrwill,
If the apps that are on your son's iPad were purchased under his Dad's Apple ID, then signing your Apple ID onto the iPad will not help you with updating those apps.
Also, if the iPad was sync'd with his Dad's iTunes library, then hooking it up to your computer/iTunes library, will require you to reset the iPad, and everything that was loaded under the other Library and Apple ID will be wiped out.
Can you provide a little more info about what was set up under which Apple ID and what iTunes library the iPad was sync'd with?
Cheers,
GB

TS1702 We use one ID for the Apps store for 2 iPhones. In the second profile on the Macit is impossible to update apps there is a mistake. What is the decision?

We use one ID for the Apps store for 2 iPhones. In the second profile on the Macit is impossible to update apps there is a mistake. What is the decision?

This happens when you both use the same Apple ID for iMessage. To fix this you have two choices:
On one of the phones go to Settings>Messages>Send & Receive, tap the ID, sign out, then sign back in with a different ID. Note: you can still share the same ID for purchasing in Settings>iTunes & App Stores; or
On both phones go to Settings>Messages>Send & Receive and uncheck the email address(es) shown under "You can be reached by iMessage at". Also uncheck the other phone's phone number, if present.

What are the uses of ThreadLocal

Hi all,
Can anyone give me an example on the use of ThreadLocal class. Does static methods need to be synchronised when working on ThreadLocal variables ?.

Antony Paul

Hi,
I think the documentation for ThreadLocal is pretty good:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/ThreadLocal.html
You usually use a ThreadLocal when you have several threads that needs to have its own local data.

Can I use a network hard drive to store my music

This might be more of an Itunes question, but I would like to know if there is a problem using a network Hard drive to store all my music on? I'll be using 2 computers to access it, 1 computer handles my kids for there Ipods each having there own logins, and the 2nd computer for my Ipod..
Or do I need to have one computer with 3 seperate logins.. I just want to do things the right way without violating anything.
Thanks for your help.

No problem with using network drive. Many do.
Easiest when doing this from the start but can be done at any time. Some things will depends on drive. For me, only one can access drive at a time. create a folder on network drive for the library to be in. For each user on each computer map the folder on the network drive to a drive letter. Set iTunes to use this mapped drive as the library location.
Notes to be aware of. Each user will have access to all files on network drive. Files added by one user will be accessible to other users but they must manually add them to their own library. If multiple users subscribe to same podcast there will be duplicate files of episodes in folder. If one user deletes a file from device other users will be affected if tracks was in their library.

Create a NEW account using these instructions. Make sure you follow the instructions. Many do not and if you do not you will not get the None option. You must use an email address that you have not used with Apple before.
Creating an iTunes Store, App Store, iBookstore, and Mac App Store account without a credit card
Using those instructions you may also be able to select PayPal if that is allowed in your country.
