hi
I have a requirement i.e. how to create a dynamic variable in bpel process?
Help me out with this....thanks.

Open your bpel and look for and icon that looks like this... (x)

How to create a local variable in bpel?

Hi,
In my bpel flow I need to call service based upon a pl/sql procedure multiple times. The procedure returns the results of a query in chunks and contains a boolean as an output parameter that tells me whether there are any more records that need to be fetched based upon which I will be calling the service again. I want to achieve this using a while loop. So for the while loop condition I am thinking of creating a local variable in the bpel process and assign it an initial value of false(). Then once the service is called I will set the value of this variable to the output boolean parameter returned by the procedure. So while the boolean is true the service will be called again.
My question is how can I create a local variable in bpel and assign it an initial value of false. Or is there any other way that this can be achieved?
Thanks!!

Hello! thanks for yr response.
I tried creating a new variable by defining a scope. But in the create variable window I cannot define a standalone variable of boolean type I need to pick up the type from an lov that brings up a list of all existing variable! so basically u are just mapping to an existing variable which in my case will not work because I will need to map to one of the elements of the output of the pl/sql procedure based service -- also this element itself is not exposed in the lov only the name "inputParameters" is displayed as the element --all the contents are not exposed.
Any suggestions?
Thanks!

Generating dynamic Attachments between bpel process activities

Dear Experts,
Please suggest me that how to handle dynamic attachments in BPEL process with JDeveloper.
The requirement was need to send an attachment between activities in same BPEL process
and not sending an attachment through mail.
For Instance consider a scenario "Need to issue an appointment order(Activity3) for the candidate if he successfully completed his assigned task(Activity1) and selected(Activity2)".
Thanks ,
Rajesh

Hi Rajesh,
That's a nice requirement without using the Notification services to send the attachments.
However, this can be achieved using the workflow service tasks as mentioned in : http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28981/workflow.htm#BABCAIEF
Using this you can assign, play with attachments via tasks. Hope this helps to some extent!

Error implementing dynamic callback from BPEL process

Hi,
I am trying to use dynamic callback from a BPEL process..
Created a variable of type EndpointReference by importing the ws-addressing.xsd. in the partnerlink wsdl..
I assigned the URL to the variable's address field ...
<copy>
<from expression="'http://172.31.171.123:8888/PubSubWLPOC-CallbackSvc2-context-root/EIPWFServiceCallbackPort'"/>
<to variable="ep_var" query="/ns3:EndpointReference/ns3:Address"/>
</copy>
Gives no error till now...
But when I try to assign the same variable to the partnerlink, I get an error..
<assign name="Assign_7">
<copy>
<from variable="ep_var"/>
<to partnerLink="MyWebService1"/>
</copy>
</assign>
The error is like this(from the $SOA_HOME\bpel\domains\default\logs) :-

The confusing part is when I use xml fragment instead of the variable ep_var, it works fine ...
But I cannot use the same as the callback can be made to any url(which is decided on runtime)
Can someone pls help me with this ?
saptarishi

Hi,
I have done following for dynamic call back and it works..
<copy>
<from>
<_EndpointReference xmlns="http://schemas.xmlsoap.org/ws/2003/03/addressing">
<Address/>
</EndpointReference>
</from>
<to variable="EndpointUrl"/>
</copy>
<copy>
In the above assignment from part is an xml fragment assigned to Endpoint Url
<copy>
<from expression="'http://172.31.171.123:8888/PubSubWLPOC-CallbackSvc2-context-root/EIPWFServiceCallbackPort'"/>
<to variable="ep_var" query="/ns3:EndpointReference/ns3:Address"/>

</copy>

<from variable="EndpointUrl"/>
<to partnerLink="SFDC_plt"/>

Creating simple Business Rules in BPEL process

Hi,
I have an environment consisting of SOA Suite 11g running on Weblogic Server. I'm using JDeveloper 11g for development.
Scenario
I have a BPEL process which starts off by polling a DB table and I then assign the input to a Recieve activity's InputVariable. I have a 'Number' column which will contain a number between 1 and 3. I then require Business Rules (BR) to be set up which read this value, and based on the number, assign a 'Name' string (which is to be the output variable from the business rules) to be used later on in BPEL process.
Problem - I have followed the basic tutorials available in order to set up the business rules, but am getting numerous errors. Firstly, I sometimes find that my input/output variables created during setup of BR component and the XSD based on this, does not have XML Faces automatically created for it (therefore have to create it myself by clicking on the + button and doing this for each element of XSD). When I do get this working, I then double-click on my Business Rules activity in my BPEL process, only to find that the input/output variables here no longer are assignable to my BR input/output variables as I get the following error "Exception: Problem Building Schema!".
I am not sure why this is, but suspect that my XSD (which is very simple anyway) or the setup steps I follow to define the link to my XSD, are wrong.
I have taken the following steps so far:
1. Create empty BPEL process
2. Set up polling adapter to poll DB table
3. Create Receive activity and assigned polled input to created variable
4. Add Business Rules component to composite and set up and create dictionary here. Also set up inputs/outputs to be in form of my XSD elements.
5. Add Business Rules component to my BPEL process and configure this to include input/output variables (*This is where error occurs*)
6. Go back to .rules component in composite to define rule and define rule
Upon deployment, I get many errors most of which pertain to "Unresolved XML element... make sure XML element +xxxxx+ is defined in one of WSDL's that are referenced by the deployment descriptor."
I have only imported a simple XSD containing two elements to this project. The other XSD is the one of my polling adapter. I've not created any input/output variables for the overall BPEL process as didn't think I was required to.
Can you please help in getting this process doing the simple activities described at the top.
I appreciate your help.

Hi,
Create a project with BPEL composite
Now drag a business rule
Now create input variable of type ur requestelement
and output variable of type response element
Now in rules designer page take decision table
and then craete a condition (inputelement.input > 1000) and in the rule select true
now create another rule select false
Npw create an action with assertion and select the parameterized box there
now in designer page for first rule assign some value (say 500) and for second rule some value(100)
Now in bpel u have to assign a value to input var of BR
Deploy the process
If u supply 10000 u will get 500
if u supply 100 u will get 100
In the same way u can do by using If-Then
You can use facts and bucketsets according to ur requirement

Error creating web service proxy for bpel process in jdev 10.1.3

Hi,
I am trying to create a web service proxy in Jdeveloper 10.1.3, and get the following error:
Element type "fault" is missing required attribute "name"
I have created a fault on one of the operations, and in the .wsdl file there is a name attribute:
<operation name="process">
<fault name="TestError" message="client:TestErrorMessage"/>
</operation>
The fault definition in the .wsdl obtained from the process when you access it over http is somewhat different:
<fault>
<soap:fault name="TestError" use="literal" encodingStyle="" />
</fault>
Any ideas how to workaround this problem?

Can we define 'Static Variables' in BPEL process ?

Is the idea of 'STATIC VARIABLES' supported in Oracle BPEL?
What I mean by that is, I need all my in-flight BPEL process INSTANCES to read a common variable and then decide the next course of action.
Is this possible?
Thanks in advance,
Mahendra

Hi Hans,
In Cocoa and Objective-C a static variable needs to be declared in the implementation file and not the header as you would normally do. Standard C variables can be set at the same time as the declaration but Cocoa objects need an extra step.
For example:
#import "TestObject.h"
// declare your static variable here
static NSArray *count;
@implementation TestObject
- (id) init {
self = [super init];
if (self != nil) {
// set the variable here
// the 'if' statement ensures it is only set once
if (!count) {
count = [[NSArray arrayWithObjects:@"One",@"Two",@"Three",Nil] retain];
return self;
@end
Hope this helps,
Martin.

How to assign a parent or child process to BPEL process Dynamically

Hi friends,
root_id (varchar) - the conversation id of the instance at the top of the invocation tree. Suppose A -> B -> C, root( B ) = A, root( C ) = A, parent( B )= A, parent( C ) = B. This instance, instance at the top of the tree will not have this set. There will be relation between ROOT_ID, PARENT_ID and CIKEY in the cube_ instance at dehydration data base.
Here I want to assign root_id or parent_id dynamically to my bpel process dynamically. Let me know if anybody knows about that.
Thanks in advance...
Hari Mandadapu

Hi,
I'm more puzzled as to why you would want to do this? As you have explained these columns provide details of the process tree. Why would you want to alter the values set by BPEL there by changing the process tree it created?

Creating dynamic variable names

I know there has got to a way to do this but I am not finding anything on google. I want to create a dynamic variable name like name + i so when your in a loop the names come out name1, name2 and so on till however many you want. I have tried
int name + i = 3;
int name[i] = 3; // which obviously won't but I had to try
int name{i} = 3;and I am out of ideas. Thanks for all your help.

I'd suggest using variables named j or x when posting code which uses them as array indexes.
[i] - is for italics formatting
[u] - is for underlined formatting
[code] is for class Example { ... } code formatting
etc.

BPEL Process in BPM Studio

Hello,
First, are there any examples, tutorials, or documentation on how to create and run a BPEL process within BPM Studio (5.7) ?
I've gotten quite a ways by trial and error, but am having trouble running / testing out the process.
I've tried doing a Process->Generate Process Interface and Process->Run but nothing happens in BPM Studio when these are performed. What else do i need to do to test out my BPEL process with external webservice ?
Here's the steps i've taken so far.
1. Developed a simple external webservice with netbeans (JAX-WS).
2. Generated WSDL and XSD with wsgen executable.
3. Developed WSDL & XSD for BPEL Process request & reply.
4. Created a new project within BPM Studio.
5. Created a new module under "Catalog" for wsdl introspection.
6. Cataloged webservice component with local wsdl/xsd files.
7. Configured the Server configuration generated under the "External Resources" to point to the webservice host.
8. Configured the web service under "External Resources" to point to the webservice endpoint on the host (Server configuration)
9. Created a new BPEL Process.
10. Created new Instance variables for the process input and output as "component" type that point to the introspected request & response types.
11. Assigned the port type & method of the BPEL Receive to the introspected service defined in #3.
12. Assinged the input variable to the request variable created in #10.
13. Assigned port type & method & output variable to the BPEL reply.
14. Created a BPEL Invoke node between Request & Reply.
15. Assigned port type & method on the Invoke node to instrospected web service defined in #2.
16. Created instance variables for input & output of invoke node based on introspected request & reply
17. Assigned input & output.
Once all of this was complete, doing a Process->Check Design yeilded no errors or warnings.
Thanks for any help,
Chris

Problems in invoking BPEL process

Hi there,
I created with JDeveloper the following BPEL process :
<?xml version = "1.0" encoding = "UTF-8" ?>
<process name="ProvaBPEL" targetNamespace="http://xmlns.oracle.com/ProvaBPEL"

which gets as input a WSLA type (http://www.research.ibm.com/wsla) and returns it as output without performing any operation (just a copy operation).
I have deployed the process and it can be accessed at http://localhost/8888/orabpel/default/ProvaBPEL/1.0. I can see it in the BPEL Console but (first problem) I can't test it because I can't see the usual HTML form the BPEL console shows. I can't see the origine xml form too. If I go to the BPEL endpoint I see the following error message:

The client simply parses an XML file and uses it as bosy of the SOAP message.
JDeveloper compiles it without errors but when I run the project (second problem) I get the following as SOAP response:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/><env:Body><env:Fault xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>env:Server</faultcode><faultstring>java.lang.NullPointerException</faultstring><faultactor></faultactor></env:Fault></env:Body></env:Envelope>
and I can't see any instance of the BPEL Process in the BPEL Console. I'm quite sure the SOAP message is well formed because I can see it in the Running output. I also tried with simpler BPEL process for which I can see the HTML form in the BPEL Console and copying and pasting the SOAP message generated with my client in the Origine XML form the Process was invoked correctly.
Can anybody help me? Thanks in advance.

Great! Thank you for the reply! Now I manage to invocate the BPEL process. I put the line:
smsg.getMimeHeaders().addHeader("SOAPAction", "process");
and now my day is a good day!
However I tried to place the import of the WSLA093.xsd schema outside the types element with:
<import namespace="http://www.research.ibm.com/wsla" location="WSLA093.xsd" />
but it didn't work. Now the wsdl file of the BPEL Process is:
<?xml version="1.0" encoding="UTF-8"?>

Please tell me if it is correct. I also tried to delete the line:
<import namespace="http://www.research.ibm.com/wsla" schemaLocation="WSLA093.xsd" />
from the types element (even if I don't know if it is correct) but I always have the same error in the BPEL endpoint page:
Cannot test this Operation using the Test Page because Could not understand type: {http://www.research.ibm.com/wsla}StringList
Thank you very muche for the help.

[Workaround] Calling BPEL process from jspx causes DCA-40012 error on AS

Hi!
I've created a DataControl for my BPEL process in my application (ADF BC 10.1.3.3).
I've created command button on my jspx page that has ActionListener binded to a backing bean method that calls commit and than my BPEL process through the bindings.
The process consists of reading some DB data, creating XML message and saving it to disk.
If I run my application from JDeveloper, everything is working fine, the file is written to desired folder. But after I deploy my application to AS 10.1.3.3 and try to call the same process, it doesn't get executed. I see this error in log files:
Exception:

I read about bug 5878326 and tried applying the patch Patch for 6404865(Base bug 5878326) in my JDeveloper (on my local machine, not on AS, since there is no JDev on the server).
But this patch doesn't solve my problems. Is there another patch for this or this behavior isn't the same as in bug 5878326?
Thanks, BB.

Hi BB,
It's Phil again.
Thanks for the follow up, especially you aren't working on this subject any more. This is indeed a bug in 10.1.3.3, but not on 10.1.3.1 Application Server. Embedded OC4J server in JDeveloper 10.1.3.3 doesn't produce this error at all. Patch for 5878326 does NOT solve this issue.
However, I have found a walk-around for this issue. Most if it has already being documented.
Oracle recommend two options to access a Web Service, by creating a Web Service Data Control or a Web Service Proxy.
See more info: http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html?_template=/ocom/print
Both approaches work on JDeveloper 10.1.3.3, but the prior option will fail on App Server 10.1.3.3 due to the bug being discussed in this thread.
For the time being, we can opt for the second option. A quick example is provided below.
- Construct a Web Service Proxy by right-click on chosen project, select New ... | Business Tier -> Web Services | Web Service Proxy, provide WSDL URL and complete the wizard. a Web Service Proxy is generated for you at (your package).proxy under Application Sources folder.
- Select this proxy, switch to Struture view, you will see a list of classes contained in the proxy. Look for a class with name (Web Service Name)Client.java. In my case, it is called __soap_getCustomerDB_getCustomerDB_pttClient.java. This class is of particular interest to you, as it provides an interface to invoke Web Service calls, in this case, getCustomerDBSelect_id(GetCustomerDBSelect_id id).
- Now create a new class, which you may extend from the example class below.
/********************** CODE BEGIN *********************************/
package oracle.srdemo.datamodel;
import java.rmi.RemoteException;
import oracle.srdemo.datamodel.proxy.__soap_getCustomerDB_getCustomerDB_pttClient;
import oracle.srdemo.datamodel.proxy.types.com.oracle.xmlns.pcbpel.adapter.db.top.getcustomerdb.GetCustomerDBSelect_id;
import oracle.srdemo.datamodel.proxy.types.com.oracle.xmlns.pcbpel.adapter.db.top.getcustomerdb.CustomerCollection;
public class WsCustomer {
__soap_getCustomerDB_getCustomerDB_pttClient myPort = null;
public WsCustomer() {
try {
myPort = new __soap_getCustomerDB_getCustomerDB_pttClient();
} catch (Exception e) {
e.printStackTrace();
* @param customerId
* @return
public CustomerCollection getCustomer(int customerId) throws RemoteException {
GetCustomerDBSelect_id id = new GetCustomerDBSelect_id();
id.setId(String.valueOf(customerId));
return myPort.getCustomerDBSelect_id(id);
/********************** CODE FINISH *********************************/
- Save the class, rebuild the project.
- Right-click on this class and select 'Create Data Control'. You should find a new Data Control named (Your Class Name)DataControl is generated on Data Control Palette.
- You can drag-and-drop available methods from the data control onto you jspx page, rebuild and test it on embedded OC4J Server.
- Deploy the ear or war file on App Server.
Hope this helps.
Regards,
Phil

Dynamic properties in a process

Hi everyone,
I am trying to find a solution to create some dynamic properties in my process.
JPD are good but too many things are hard-coded and changing them needs the project
to be recompiled :(
My aim is to remove most of the hardcoded values and let the administrator set
them later at the deployment time.
Do you have any idea if it is possible to add custom dynamic properties that could
be edited in the same way as the service broker control ?
Moreover some of the process settings are in the javadoc (such as the delay for
a timer path, the amount of retry for an exception etc..)
Is there any solution to set them at the runtime ?
Thanks for any help/idea you could provide,
Mael

You can get the task infromation by calling the task control method TeskInfo getTaskInfo()

Dynamic variable and/or XML LazyLoader HELP

I am loading images via xml lazyloader into my air app
I need var b to be "img" + item.id dynamically
any ideas???
for each (var item : LoadingItem in lazy.items)
var b : Bitmap = lazy.getBitmap(item.id);
addChild(b);
If you dont know the lazyloader code then can you please explain how to create a dynamic variable for a bitmap???

so i should set type here
var img:bitmap = {}
then create the variable like this in my for statement?
img[this[item.id]] = lazy.getBitmap(item.id);
lets say item was 1,2,3
Then
img[1]
img[2]
img[3]
would be able to hold a different bitmap
thanks in advanced
