10.1.3, Session Edior, Specifying custom session event listener

When in 9.0.4.4, we can specify custom sesson event listener in session editor.
Using 10.1.3 mapping workbench/session editor, I haven't found a way of doing it. Is this supported?
Thanks.
Haiwei

Never mind. After adding jar to the classpath, I now can specify custom sesson event listener in the session editor. Thanks.

The service is working fine from a web page that my coworker did. I have not installed soap UI yet, but I used it at my last job. Since I posted this I have a new computer, have installed BizTalk Server 2013 R2 and Visual Studio 2013 Premium.
This is what I've done...
Created a new Host called BizTalkServerApplication64 with the '32-Bit only' unchecked.
Created a new host instance using the new host.
Created a new Send Handler for both Adapters 'WCF-BasicHttp' and 'WCF-Custom' using the new host.
configured both Send Ports (WCF-BasicHttp and WCF-Custom) to use the new send handler.
Have tried binding the logical port to both basic and the custom ports.
Now I get a different error which is:
Error Description: System.ServiceModel.CommunicationException: An error occurred while receiving the HTTP response to http://lbenson/MDSVC2/Service1.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due
to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. --->
System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host...
Any suggestions for this error? I'm not sure if this means I'm closer to getting it work or further.
Thanks for your help!

Postmerge session event question

We have implemented a custom session event listener that utilizes the postmerge session event.
We have observed some unexpected behavior and were hoping that the product architect or manager could explain this behavior.
We have the following graph of objects:
A has a many-to-many privately owned collection of B
B in turn has a many-to-many privately owned collection of C
After commiting a transaction involving object A we observe:
postMerge event for A
postMerge event of each of A's privately owned Bs
yet NO postMerge event for any of B's privately owned Cs
Questions:
1) Is this the expected behavior?
2) Since we need to do some processing of Cs, we are using the postMerge event that occurs on Bs to update the Cs. Is this a safe/correct approach?
3) In a transaction that involved only updates to Cs, (no changes to A or B), would we see a postMerge event for each updated C?
Thanks in advance for any clarification you can provide.
...Steve

You could paste the results (tkprof ?) of the trace.
The "missing" time could be an uninstrumented wait --- i.e. a wait event that is not captured in v$session_event. Particularly because you are using external calls.
For example, see "Case Study 1" at http://blog.tanelpoder.com/2007/08/27/advanced-oracle-troubleshooting-guide-part-2-no-magic-is-needed-systematic-approach-will-do/

How to specify custom SQL in polling db adapter with logical delete option

Hi all,
I am writing a SOA composite app using JDeveloper SOA Suite 11.1.1.4 connecting to a SQL Server db using a polling DB Adapter with the logical delete option to send data to a BPEL process.
I have requirements which go beyond what is supported in the JDeveloper UI for DB Adapter polling options, namely:
* update more than one column to mark each row read, and
* specify different SQL for the logical delete operation based on whether bpel processing of the data polled was successful or not.
A complicating factor is that the polling involves two tables. Here is my full use-case:
1) Polling will select data derived from two tables: e.g. 'headers' and 'details' simplified for this example:
table: headers
hid - primary key
name - data label
status - 'unprocessed', 'processed', or 'error'
processedDate - null when data is loaded, set to current datetime when row is processed
table: details
hid - foreign key pointed at header.hid
attr - data attribute name
value - value of data attribute
2) There is a many:1 relationship between detail and header rows through the hid columns. The db adapter polling SELECT shall return results from an outer join consisting of one header row and the associated detail rows where header.status = 'unprocessed' and header.hid = details.hid. (This is supported by the Jdeveloper UI)
3) The polled data will be sent to be processed by a bpel process:
3.1) If the bpel processing succeeds, the logical delete (UPDATE) operation shall set header.status = 'processed', and header.processedDate = 'getdate()'.
3.2) If bpel processing fails (e.g. hits a data error while processing the selected data) the logical delete (UPDATE) operation shall set header.status = 'failed', header.processedDate = 'getdate()', and header.errorMsg = '{some text returned from bpel}'.
Several parts of #3 are not supported by the JDeveloper UI: updating multiple columns to mark the row processed, using getdate() to populate a value of one of those column updates, doing different update operations based on the results of the BPEL processing of the data (success or error), and using data obtained from BPEL processing as a value of those column updates (error message).
I have found examples which describe specifying custom SQL using the polling delete option to create a template then modifying the toplink file(s) to specify custom select and update SQL to implement a logical delete. (e.g. http://dlimiter.wordpress.com/2009/11/05/advanced-logic-in-oracle-bpel-polling-database-adapter/ and http://myexperienceswithsoa.blogspot.com/2010/06/db-adapter-polling-tricks.html). But none of them match what I've got in my project, in the first case because maybe because I'm using a higher version of JDeveloper, and in the second I think because in my case two tables are involved.
Any suggestions would be appreciated. Thanks, John

Hi John,
You've raised a good scenario.
First of all let me say that the purpose of the DB polling transaction, is to have an option to initiate a process from a DB table/view and not to update multiple fields in a table (or have other complex manipulation on the table).
So, when choose to update a field in a record, after reading it, you are "telling" the engine not to poll this record again. Sure, i guess you can find a solution/workaround for it, but I don't think this is the way....
The question now is what to do?
You can have another DB adapter where you can update the data after finishing the process. In that case, after reading the data (on polling transaction) - update the header.status = 'processed' for example, and after processing the selected data update the rest of the fields.
Hope it make some sense to you.

How to specify custom table name for subclasses in Kodo 3?

I'm migrating our codes from Kodo 2.5.x to version 3.
In Kodo 2.x, specifying the class/subclass table name uses the extension
like this "@jdo.extension vendor-name="kodo" key="table"
value="DyeStuffs"" when using XDoclet to generate the .jdo metadata files.
It no longer works in Kodo 3. Following the Kodo's documentation, I have
upgraded XDoclet to 1.2b3 and changed all doclet tags to the ones that
XDoclet understands.
I noticed in the documentation, to specify custom table mapping, it uses
nested vendor extensions. E.g
<extension vendor-name="kodo" key="jdbc-class-map" value="vertical">
<extension vendor-name="kodo" key="table" value="TABLOID"/>
<extension vendor-name="kodo" key="ref-column.JDOID"
value="MAG_ID"/>
</extension>
So how do I specify nested extensions when using with XDoclet's tags?
Need help as I have to complete the migration by end of the week.
Thanks,
Makas

Does it mean I have to map all classes and fields to the existing tables?As I tried to point out earlier, in 3.0 all mapping information must be

long as you're not using XDoclet for all your mapping! :)
It seems quite a pain to manually map all the existing tables and
fields, especially when Kodo gave the table and field names. I don't
mind mapping the tables, but mapping the fields will be a horror with
105 tables. Have I missed out anything in the migration documentation
that might help me with this process? Also does Kodo require the
..mapping file to work or having everything in .jdo file is sufficient
(looking at the documentation it seems ok to have .jdo file only)?
If I do, I prefer to regenerate all tables without the base table,
basically having tables to include all the fields from the base table.
And migrate all existing data to the new table structure.I'm not entirely clear on what you want. Are you saying that you want
each subclass to have its own table and repeate the columns from its
superclass table in its own?
Yes, that is exactly what I want.
If so, then this is not supported by Kodo (yet... we're working on it
though).
Ok, I'll settle having Kodo 3 to only map back to the original tables,
as I believe Kodo 3 will provide some performance improvement as
compared to 2.x.

WebDynpro ABAP - inter session events possible?

Hi Experts,
I have a ABAP-WebDynpro application with various tabstrips to show and maintain process data within a production process. Each tabstrip contains several data of a specific process step. At the beginning, very few data are already present. While production progresses, chemical analysis is being taken and machine data is gathered. Assoon as new data for the process step is available, a refresh should be performed.
Though not perfect in every aspect, we made this scenario work in a similar way in ABAP Dynpro by using inter session eventing (ISE). Is there a possibility to trigger events in WebDynpro cross-session - for example after adding data to the database?
Best regards
Jens

There is no real cross session eventing available in Web Dynpro. The problem is two fold. First, UI updates can't be initiated by the server in HTTP (unlike the SAPGUI which does have a push mechanism to the client). This is a current limitaiton of HTTP itself and not something Web Dynpro related. So to trigger the phase model of Web Dynpro, something must occur on the client to trigger the server event. In NetWeaver 7.0 and 7.01 you have to use the timedTrigger UI element to acomplish this:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/da/a6884121a41c09e10000000a155106/frameset.htm
You then generally used a shared memory object (or even temporary database entries) to communicate data or events between to different processes. For instance a background job is running and places it status in a shared memory object attribute. The Web Dynpro can then fire a TimedTrigger every minute to check the value of this shared memory object attribute.
In NetWeaver 7.02 we improve this process with a new capability called the Web Dynpro Notification Service. Instead of the timedTrigger, we can simulate a push of data/events to the client using AJAX. We open an secondary server request to the ICM to check the status of an event. That way we don't have to disrupt the client side activity or incurre the full Web Dynpro Phase Model until we know a change in the status of our event has occured. Also since the status info is stored in the ICM Cache, you don't even have to fall into an ABAP Workprocess to check the status.

Creation of Flex Components Listening to a Custom Flex Event

Hi,
I would like to create a component in Flex which will always listen to a Cutom Event.
Say, I create an event named "MyEvent" in Flex. I associate this event toa custom component, say MyComponent (extends Button). When ever this even is triggered , I should have a set of Components listening and tracking this event using an event listener in their definition.This should be in a framework level. That is, even if we add more components in our application, they should be able to listen to the Custom Event.
Or in short, is it possible to make all the components in an application listen to a custom event triggered?

Thanks for your answer.Can u please give an example so that I can understand it.Excuse me,I am a beginner in flex.

When to use Custom Adapter, Event Beans and Spring beans

Hi,
I have basic question on when or on what basis/scenario the Custom Adapter, Event Beans or Spring beans should be used.
All three has same implementation methods.
Please help me in understanding when to use Custom Adapters, Event Beans or Spring beans.
Thanks,
Sri
Edited by: 897694 on Mar 7, 2012 8:12 AM

custom adapters:
you have to use a custom adapter when you don't find any adapter in ocep which will serve your purpose.
Most of the times you use an adapter to connect the application with external things like http server, etc It can be both to listen the events or to send the events outside.
Event Beans:
This type of beans does most of the work that an adapter code does but in convention beans are not used to connect the application with external stuff
You can use Beans as event sink etc In this case using an using an adapter is not suggestable.
If you implement Interfaces like Initializing Bean for an adapter code it won't work properly, you have to use an event Bean in that case.
Spring beans:
Spring beans are used when the bean code doesn't implement EventSink or EventSender.
These beans are used to enable something (eg: make ${wlevs_dev_home}/abc/a/b.java this path is not understandable by java code unless you override the path using a spring bean)
Most of the things which doesn't need a connection between components in the application (eg cache loader: you can do this using spring beans and event beans both but spring beans doesn't need a connection with cache)
Hope this small writeup helps you :)

How does custom event listener work.

Hi,
With reference to Custom Event Listener, I wanted to know the behaviour of Custom Listener whether they are sync or async.
For Example :
Suppose i have a method1() which has the listener1() get invoked at some operation at line #1 of method();
The task of listener1() takes 2 minutes aprox.
Then my question is does method1() waits until listener1() finishes its task(2 Minutes) ?
What is he default behavior of listner1()
Can we change the default behavior of custom listners ?
Thanks & Regards,

How to enqueue custom AWT event?

hi,
in my applet I need to use custom AWT events. I subclass them from java.awt.AWTEvent and set their id to higher as AWTEvent.RESERVED_ID_MAX - as recomended in documentation.
But how to enqueue such event? A tried to use following approach:
getToolkit().getSystemEventQueue().postEvent( myEvent );
and it works fine - but only in browsers usings Sun's VM implementation. In browsers using Microsoft's VM I'm getting following exception:
com.ms.security.SecurityExceptionEx[matlu/client/ClientConnection.enQueue]: Event queue access denied.
So the question is: is there any other way to enqueue custom event, which will keep Microsoft's security manager happy?
thak you very much
Lubo Matecka

I know it must be visible... (But it doesnt have to be bigger than 1 pixel...)
The code I posted is just to illustrate the idea.
If you need to post multiple events you just replace the AWTEvent member with a LinkedList (or some similar FIFO).
Then in postEvent you do theLinkedList.addFirst(yourEvent)
And in paint() you do AWTEvent ev = (AWTEvent)theLinkedList.removeLast();
process ev.
if(theLinkedList.size() > 0)
repaint();Yes. I have run into the same problem, and I did not use the repaint- trick...
My applet communicates with the server in a separate thread. When a response receives the communication thread should post an event to the AWT- thread to get the response processed.
My solution here is to process the thread in the communicator- thread. This is a bad solution because it might create multithreading bugs.... but it has proven to work ok in practice.
Another example is like this. The use presses the mouse at Component B so that:
1 Component A gets a focusLost event.
2 Component B gets a mousePressed.
3 I want to do something in component A that should be done after component B has processed the mousePressed event. This can be solved without using events. You just have to write some more code (You are already in the right thread).
