[q] variables not seen in WLPI business operation window

Question

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

Answer 1

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 :
<<wlpirequest>
<started>2001-08-09 16:38:24.080</started>
<requestor>wlpisystem</requestor>
<templateid>5001</templateid>
<template-name>test</template-name>
<templatedefinitionid>4001</templatedefinitionid>
<instanceid>9008</instanceid>
<actions>
<error time="2001-08-09 16:38:26.391">WorkflowException: An error
occurred
during exception handler processing.
Empty instance object for business operation "CreateReply"
in template
"test".</error>
</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,

Hi,
Can you please elaborate your reply.
I am also facing the same problem. Instance variable defined is notseen in the
drop down box. Please help me.
Thanks,
Ravi.

Starting from WLPI 2.0, the business operation will do automatic
type
filtering on variables that perform business operation, and variables
that
to be assigned the result of business operation. This filteringreflects
WLPI variable casting policy which is documented.
Please reexamine types of your variables and see if the filteringmakes
sense to you.
