How to Handle Multiple Instances of Page

Hello All,
I'm developing a new page in a Statefull BSP Application.
The Page is developed using View and Controller.
Controller has an instance of a Business Object. Business Object contains the Business Logic.
Everything works untill user opens a single Window, But when user Right Click the Tree link and open another Instance of the same page, then the problm starts.
In this case Both instances of the page are in the same Internal Session, Hence they share the same instance of the Business Object. Hence the Systems behaves unpredictabily.
Can anybody give me some hints to get rid of this issue?
Thanks & Regards
Geogy

Hi Vijay,
Thanks for the reply, But that's not the right aproach.
I cannot change the application to stateless, Since the standard application where the page resides is statefull.
Also some of the business logic I cannot achive with stateless application
Regards
Geogy

How to handle multiple request in the servlet

how to handle multiple request in the servlet...
Example:
java forum...
i'm login in the java forum at this time 1000 members make login in this....how happended in servlet?
if we use thread how to implement in servlet ?

Serlets are already threaded. The application container instantiates the servlet, then uses this instance in a new thread for every use.
This is the reason that you should use (almost) no instance variables in a Servlet, but rather that (almost) everything should be local to the method.

How to handle multiple tables data in Entity Beans?

How to handle multiple tables data in Entity Beans?
i mean, my bean (non trivial) is responsible for frequent
insertion in one table and some deletion on another table.
Can anyone of you...please..?

Is your data model right? If you are adding in one and deleting in another it sounds to me more like a process that an entity, in which case you may revisit your data model and simplify it, add in a session bean with the process method to co-ordinate between the two.
However, if you want to map multiple different tables within a single entity bean it is possible and just part of the mapping. How you actualyl specify it depends on which implementation you are working with.

How to handle multiple datasources in a web application?

I have a J2EE Web application with Servlets and Java ServerPages. Beside this I have a in-house developed API for certain services built using Hibernate and Spring with POJO's and some EJB.
There are 8 databases which will be used by the web application. I have heard that multiple datasources with Spring is hard to design around. Considering that I have no choice not to use Spring or Hibernate as the API's are using it.
Anyone have a good design spesification for how to handle multiple datasources. The datasource(database) will be chosen by the user in the web application.

Let me get this straight. You have a web application that uses spring framework and hibernate to access the database. You want the user to be able to select the database that he wants to access using spring and hibernate.
Hopefully you are using the Spring Framework Hibernate DAO. I know you can have more that one spring application context. You can then trying to load a seperate spring application context for each database. Each application context would have it's own configuration files with the connection parameters for each datasource. You could still use JNDi entries in the web.xml for each datasource.
Then you would need a service locater so that when a user selected a datasource he would get the application context for that datasource which he would use for the rest of his session.
I think it is doable. It means a long load time. And you'll need to keep the application contexts as small as possible to conserve resources.

How to handle multiple actions in the webservice ?

Hi Guys,
I have multiple operations in the webservcie and under soap action in the receiver soap adapter, i dont know how to handle multiple soap operations.
can anybody guide me, how to acheive this ?
Thanks,
srini

Hi Srini !
This weblog shows the general design of a scenario with BPM
/people/krishna.moorthyp/blog/2005/06/09/walkthrough-with-bpm
This link:
http://help.sap.com/saphelp_nw04/helpdata/en/de/766840bf0cbf49e10000000a1550b0/content.htm
show how to insert a predefined BPM pattern. You could use one of the BpmPatternSerialize.... patterns to see how you BPM should look like...
Basically it should be:
1) Receive Step (async/sync, as you need) to trigger the BPM
2) Send step (sync) for first webservice
3) Send step (sync) for second webservice
N) Send step (sync) for N webservice
N+1) if the whole communication is sync, here you need to use a send step to return back the answer to sender.

How to handle multiple site to site IPsec vpn on ASA, any best practice to to manage multiple ipsec vpn configrations

how to handle multiple site to site IPsec vpn on ASA, any best practice to to manage multiple ipsec vpn configurations
before ver 8.3 and after version 8.3 ...8.4.. 9 versions..

Hi,
To my understanding you should be able to attach the same cryptomap to the other "outside" interface or perhaps alternatively create a new crypto map that you attach only to your new "outside" interface.
Also I think you will probably need to route the remote peer ip of the VPN connection towards the gateway IP address of that new "outside" and also the remote network found behind the VPN connection.
If you attempt to use VPN Client connection instead of L2L VPN connection with the new "outside" interface then you will run into routing problems as naturally you can have 2 default routes active at the sametime (default route would be required on the new "outside" interface if VPN Client was used since you DONT KNOW where the VPN Clients are connecting to your ASA)
Hope this helps

How to handle multiple save exceptions (Bulk Collect)

Hi
How to handle Multiple Save exceptions? Is it possible to rollback to first deletion(of child table) took place in the procedure.
There are 3 tables
txn_header_interface(Grand Parent)
orders(parent)
order_items (Child)
One transaction can have one or multiple orders in it.
and one orders can have one or multiple order_items in it.
We need to delete the data from child table first then its parent and then from the grand parent table.if some error occurs anywhere I need to rollback to child record deletion. Since there is flag in child table which tells us when to delete data from database.
Is it possible to give name to Save exceptions?
e.g.
FORALL i IN ABC.FIRST..ABC.LAST SAVE EXCEPTIONS A
FORALL i IN abc.FIRST..ABC.LAST SAVE EXCEPTIONS B
if some error occurs then
ROLLBACK A; OR ROLLBACK B;
Please find the procedure attached

If you have one or two places in your code that need multiple exceptions, just do it with multiple catch statements. Unless you are trying to write the most compact Programming 101 homework program, inventing tricks to remove two lines of code is not good use of your time.
If you have multiple catches all over your code it could be a code smell. You may have too much stuff happening inside one try statement. It becomes hard to know what method call throws one of those exceptions, and you end up handling an exception from some else piece of code than what you intended. E.g. you mention NumberFormatException -- only process one user input inside that try/catch so it is easy to see what error message is given if that particular input is gunk. The next step of processing goes inside its own try/catch.
In my case, the ArrayIndexOutOfBoundsException and
NumberFormatException should be handled by the same way.Why?
I don't think I have ever seen an ArrayIndexOutOfBoundsException that didn't indicate a bug in the code. Instead of an AIOOBE perhaps there should be an if statement somewhere that prevents it, or the algorithm logic should prevent it automatically.

Thanks in advanced.
Narasimha Rao.

Can you have a look at this post: http://redstack.wordpress.com/2010/09/30/iteratingtraversing-arrays-in-bpm/
It's solving a different problem, but the key is that it's using a multi-instance subprocess to iterate over an array of "things" that need to be acted in. In your case it's the set of results from the db query rather than the set of tests in the example. But the principle is the same. You'd take collection of rows from the DB and process them in a multi-instance subprocess. The text that begins with the following would be good place to start:
"Now let’s implement the body of our process. We will use the Subprocess object to handle the traversal of the array of tests. Drag a Subprocess from the component palette on the right into the process and drop it on the line between the Start and End nodes."
In the loop characteristics you'd define whether you want to execute serially or in parallel.

How to reference multiple instances of the same Java object from PL/SQL?

Dear all,
I'm experimenting with calling Java from PL/SQL.
My simple attempts work, which is calling public static [java] methods through PL/SQL wrappers from SQL (and PL/SQL). (See my example code below).
However it is the limitation of the public static methods that puzzels me.
I would like to do the following:
- from PL/SQL (in essence it needs to become a forms app) create one or more objects in the java realm
- from PL/SQL alter properties of a java object
- from PL/SQL call methods on a java object
However I fail to see how I can create multiple instances of an object and reference one particular object in the java realm through public static methods.
My current solution is the singleton pattern: of said java object I have only 1 copy, so I do not need to know a reference to it.
I can just assume that there will only ever be 1 of said object.
But I should be able to make more then 1 instance of an object.
To make it more specific:
- suppose I have the object car in the java realm
- from PL/SQL I want to create a car in the java realm
- from PL/SQL I need to give it license plates
- I need to start the engine of a scpecific car
However if I want more then 1 car then I need to be able to refrence them. How is this done?
Somehow I need to be able to execute the following in PL/SQL:
DECLARE
vMyCar_Porsche CAR;
vMyCar_Fiat CAR;
BEGIN
vMyCar_Porsche = new CAR();
vMyCar_Fiat = new CAR();
vMyCar_Porsche.setLicensePlates('FAST');
vMyCar_Porsche.startEngine();
vMyCar_Fiat.killEngine();
END;
Thanks in advance.
Best Regards,
Ruben

You can do this by manually creating a new iterator binding in your binding tab.
So instead of dragging the VO directly to the page, go to the binding tab, add a new executable iterator binding, and point to that one from your ELs in the page itself.
