Business operations in the studio

I have an existing web based application already running on weblogic that uses
ejbs. I want to make use of one ejb installed in this existing application in
weblogic studio to define a business operation. To do this, I guess I should also
deploy the same ejb onto "Weblogic Integration" application which is a separate
application ( or in other words add an ejbcomponent element to application element
of "Weblogic Integration" application and update application.xml in META-INF of
Weblogic/integration/lib). If I do this, this is essentially turning out to deploying
the same ejb into two applications. Is this correct. So deploying an ejb twice
in two different applications on a single weblogic server means giving them two
distinct jndi names. Is this procedure correct or is there a better alternative.

are the methods static?

Hi,
I defined several Business Operations with Java Class. Next I addedseveral
public methods in that class.
After that I tried to define new Business Operation with new method butnew
methods didn't appear in "Method to Call" combobox.

WLPI: business operations JNDI lookup & service pack

Hello,
I ran into a problem attempting to define a business operation in the Studio application
using WLPI 1.2.1 (without service pack 1). Everything works up to the point where
I press the Done button and Studio attempts to create a new business operation
object. I am getting a JNDI lookup exception. It appearsejb-name of method in
isolation-level must be the same name as that of the weblogic-enterprise-bean
Studio is looking up the name 'com.bea.wlpi.businessoperation' while the business
operation bean is bound under 'com.bea.wlpi.BusinessOperation'.
In an attempt to fix this problem I upgraded to service pack 1, but am now unable
to deploy wlpi-ejb.jar because of the following error: "ejb-name of method in
isolation-level must be the same name as that of the weblogic-enterprise-bean".
Can anyone help me create a business operation?
Thanks,
Martin

Make sure that this Datasource you created is Targetted to Admin Server and full Cluster (incase of cluster domain). From Admin Console, select your datasource and check for the Targets tab. Since its JNDI lookup error, most probably it may not be deployed properly.

[q] variables not seen in WLPI business operation window

hI,
I am assigning a java object instance to WLPI variable.
Then I try to call one of the methods of this Java Object (Using business
operation)
but in the Drop Down list in the WLPI I don't see the assigned variable !
Am I missing something ?
( I Use WLPI 2.0 on WL6.0 sp 2 )
Thanxs,
Ronen Yaari

I seem to have answered my own question...
The problem was fixed when I defined 2 business operations, a GetBusOpInstance
operation and for example, a PerformSomeProcessing business operation.
The GetBusOpInstance maps to the constructor in my class file, while the PerformSomeProcessing
business operation maps to some other public method.
I am only interested in the PerformSomeProcessing operation, but in order to use
it, i first need to create an instance of the class, So i explicitly need to call
GetBusOpInstance to do this (Remember to assign it to a java class).
Subsequently, this "instance variable" is used to execute the PerformSomeProcessing
operation.
This seems quite verbose, but can probably be overcome by using statically defined
methods. (I need to try this out to confirm it)

Hi there
I have experienced a similar problem. With the business operation in
my studio
classpath, i am able to select a workflow variable in the instance variable
dropdown
box. However, when i try to run the workflow, i get an exception when
wlpi attempts
to run the business operation :

</actions>
<completed>2001-08-09 16:38:26.393</completed>
</wlpirequest>>
It does not seem to have saved the instance variable.
However when I look at the workflow task, i can see that the instance
variable
assignment is still valid.
What gives?

Hi Ravi,
This is a known issue with WLI 2.0. The workaround for it is to put
the
Java class you are using for your business operation into the classpath
of
Studio.
Hope this helps,

Unable to find business operation

Hi all:
I am using WLPI 1.2.1.
I have a workflow whose start node is of "Timed" type i.e it triggers at regular
intervals. The first business operation that I perform after I have executed the
start node is an operation on the Java Class. This Java class has been added as
one of the business operations to the WLPI and appears as such in the BUSINESSOPERATIONS
table.
The problem I am running into is that when I start my server and the triggerring
of my workflow happens, I get an exception saying that "business operation bcLatchClosedCreate
can't be found" where "bcLatchClosedCreate" is the name of my business operation.
The Java Class which is accessed through this business operation is a public class
and I have defined business operation to instantiate and call methods on it. As
soon as this exception occurs the record (which tells what is the next time for
trigger) is deleted from the TIMEDEVENT table and no futher triggering of this
workflow occurs.
However, if I resave this workflow, triggering starts again and everything is
fine. The business is found and no exception occurs. It is only at the start of
the server that I have the problem which essentially renders the workflow useless
as no triggering happens in future.
Is there is nay programmatic way to start and stop the automatic triggering of
a timed workflow.
Following is the exception:
Fri Mar 29 13:45:07 EST 2002:<I> <EJB JAR deployment c:/marketreadyproject2/lib/wlpi-ejb.jar>

Multiple integration flows for different business operations

Hi - I have following business requirement & need ur advice.
There are different business operations (read as INSERT/DELETE/QUERY) to performed on same business object (read as CUSTOMER). In order to develop these integration use case I can have following three approaches.
*1. Single Requestor ABCS & Single Provider ABCS -* Develop single integration flow & implement logic for the business operations in them. That means, Develop single Requestor ABCS for all business operations, which will call the EBS and again EBS would call same Provider ABCS. Both Requestor & Provider ABCS would implement business logic for all business operations required.
*2. Single Requestor ABCS & Multiple Provider ABCS -* In this case the flows for all business operations starts with single point service. That means, Develop single Requestor ABCS for all business operations, which will call the EBS and again EBS would call different Provider ABCS based on the business operations. The Requestor ABCS would implement business logic for all business operations required. There would be different ABCS service for different business operations.
*3. Multiple Requestor ABCS & Multiple Provider ABCS -* In this case the completely independent flows are to be developed for all business operations. Independent Requestor ABCS and independent Provider ABCS. Off course if there some common business logic for all or some business operations, those can be implemented as common service & can used across all independent flows for different business operations.
Please do suggest what approach would be best one to pick up. Or it is case to case basis. In case yes, please suggest the criteria on which the decision can be taken.
Thanks In Advance
Priyadarshi

Hi Pryadarshi,
AIA recommends having an ABCS for each Verb and Noun combination for a specific Business Process, i.e. CreateCustomerABCS and UpdateCustomerABCS. Therefore, #3 would be the preferred approach. This is to allow for maximum flexibility. However, you may have a process that demands to model the integration as #2.
The decision would depend on how the participating application services are modeled and the granularity of individual service call. For example, a ProcessCustomer invocation at the source end may call CreateCustomer provider service.

Authorization object & Business operation for issue permit & reject permit

Hi all,
I have created a new notification type (copied from PM) and have assigned tasks to the notification. In this notification i wanted to use the icons issue permit and reject permit for certain users (but not for all). So i need to provide the business operations to the basis guy to attach it for the specified roles.
I am not able to find these business operations.
Any help on the above would be highly appreciated.
Thanks and regards,
Santosh.

Hi,
Pls check authorization object used to control the assign or issue a particular permit
Object: I_SOGEN
Sorry u can not control the authorization bcoz above object not works for notification also there is no business operation in notification to control the approval or rejection of permit.
U have to use the user status by which u can control the approval or rejection of permit.

Configuring Business Operations in WLIntegrator 2.1 Studio

Hi,
I deployed a SessionBean and few CMPs in a deployable jar on WLI 2.1.I was able
to test the deployment through a java client.
Now, when i go to a workflow template in WLI Studio and select Configuration-->Business
Operations and click on add button, I`m getting following exception on server console:

Make sure your EJB is configured in the same Application as the WLPI code
Any pointers to what may be the problem and how to solve it.
Thanks,

Hi,
check in your administration console/Deployments/EJB: the WLPI application
code is propably deployed into the WLPI_Application. I did not find another
way to tell my EJB to be deployed in the same application than editing the
config.xml (which is hopefully not the recommended way to do it).
In the config.xml should be a tag like:
<Application Deployed="true" Name="WLPI_Application" Path="lib">
insert your myEjb.jar like the following (the URI has to be relative to the
given path, in this case "lib"!):
<Application Deployed="true" Name="WLPI_Application" Path="lib"
[other WLPI applications]
<EJBComponent Name="myEjb" Targets="myserver"
URI="../../../src/toplink/tutorial/ejbtest/myEjb.jar"/>

Java.io.NotSerializableException when trying to invoke java class Business Operations in studio

According to WLI docs, the Java Class Business Operations doesn't need to be Serializeable.
But somehow everytime I try to invoke the Busines Operations in studio, It always
throws me exception : java.io.NotSerializableException. Is it something wrong
with my Java Class ? The operation seems to be executed successfully but after
that It looks like WLI is trying to serialize the object into database which can
not be done because the Java Class is not serializeable. Changing the Java Class
to serializeable is not an option since I don't have any control on this class.
Please advise...

Martin

How to create business operation for starting workflows

How to create business operation for starting workflows from worklist?
When I call methods that implements business operation from java class everything
works fine(wlpi-ejb.jar is required), but when I call business operation from
Studio I can't use classes from wlpi-ejb.jar.

Business operation is called by WLIS. So, I include wlpi-ejb.jar into WLIS classpath.
Studio uses deployed EJB from wlpi-*.jar, I don't know why Studio doesn't see
methods from deployed EJBs when WLIS classpath contains wlpi-ejb.jar.

Still got problems with java class business operations

Hi all,
I've read the latest on business operations and java class files, but my problem
remains - the workaround of putting the class file in the studio classpath did
not work for me.
To breifly recap the problem -
I am unable to assign an instance variable when trying to call a predefined business
operation of a java class. Calling the constructor seems to work okay and I can
assign the result to a variable of type "java object" but that's as far as it
goes. If I try placing the class file in the studio classpath, my "Instance Variable"
dropdown list dims, but I am still prompted to choose one when I press okay.
I'm using process integrator 2 sp2 on wls6.

What platform are you running on?
I have found the same problem when trying to run wlpi remotely.
We have a sun box with the WLI installation. When i run wlpi on that
box, and
do the business operation configuration as u describe below, i get instance
variables
populated in the drop down box of the business operation window. I can
then select
the java object my instance is assigned to.
However, when i connect remotely using the studio and try to view the
business
operation settings, nothing appears in the instance drop down box.
When i go back to the console and run the studio on the same machine
as the installation,
the instance variable drop down is populated once again.
So all i can say is, configure the workflow on the machine have the running
installation,
and then it should work. It did for me :)
Hope this helps

Business operations can only access classes from the application and extension

save,
I am getting this error.BTW, I am using Oracle 8i as Database:
--------------- nested within: ------------------
weblogic.utils.NestedRuntimeException: Error writing 'Context hashcode: '8856607
22', primaryKey: '41', flags: '', needsRefresh: 'false', needsFlush: 'true', pin
ned: 'true', ejbObject hashcode: '881204274', bean hashcode: '885136434'' to per
sistent store - with nested exception:
[java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a
LONG column
I checked my drivers and everything.I was able to successfully run the ddl
provided for Oracle and also when I created a
WorkFlow template, the name of the Template got saved into the database.
Thanks in Advance.

Hi,
I'm trying to follow the tutorial on creating a Business Operation for WLPI
1.2.1. However, I get the following errors whenever I try to add a new
Business Operation:
The server was unable to complete your request.
RemoteException: EJB Exception: ; nested exception is:
java.lang.NoClassDefFoundError
java.rmi.RemoteException: EJB Exception: ; nested exception is:
java.lang.NoClassDefFoundError
java.lang.NoClassDefFoundError
<<no stack trace available>>
===================
I'm using WLPI 1.2.1 and Java 1.3 (which from the docs seems like it should
work). Any help/insight is appreciated...
