BPM support Inheritance ?

Hi,
Is BPM/BPM object support inheritance property of OOPS concept ?
If so then how and how can we implement that in ALBPM ?
Thanks in advance.

Others have probably gotten Type inheritance to work, but I haven't been able to get it to work since 5.7 and suggest you try Behavior inheritance instead.
I uploaded a project that has XML content going to a child process and back up to the parent process successfully. This exported project is on: http://www.4shared.com/file/123127271/a7da63f0/XSDIntrospectionToChildProcess.html.
In the Catalog's "XSDIntrospect" module you'll see both the introspected XSD and the BPM Object that inherits from the XSD. Inside both the parent process and called child subprocess, this BPM Object is used as an instance variable ("po"). In this project, the values entered in the parent's XML are passed successfully to the child and then from the child back up to the parent successfully.

Does BPM support the JAVA config file feature.

Hi ,
Does BPM support the JAVA config file feature? like based on env(local, dev, test, stage, prod) BPM aaplication can have different values for the same property/variable using the config file. How can BPM identify its env (local, dev, test, stage, prod)
Thanks In Advance!

Hello Robert,
I am refering here to both C++ client and Coherence Server. Will it work in either of the cases?
Thanks,
JayHi Jay,
Coherence server: it definitely won't do anything with C++.
C++ client: for the cache store of a local cache residing within the C++ client you may be able to specify it, but it will have nothing to do with the cluster itself. I never worked with the C++ client, so I can't guarantee you can configure it that way. Look at the following page for further documentation:

Servicegen doesn't support inheritance?

I have a method in a ejb class which returns class Product. The Product itself inherits class ProductBase. The ejb itself works ok. I then wrap the ejb with webservices, using servicegen to generate serialization class, and clientgen to generate client jar and then test the web services. The problem is that I can get all bean properties defined in the Product class, not in the ProductBase. This leads me wondering if oo inheritance feature is stripped off by using servicegen. Any idea what happens? Is there any way to fix it? Will appreciate your help.

It seems to me that this is a servicegen bug. I found a another thread in the group which discussed pretty mush the same thing.

Runtime constant (Filename) errors out in BPM

Hi,
I have a BPMCollectTime scenario to collect the Source files. The filename (Message Mapping/Transformation) from the files is captured in TRANSFORM STEP(before sending them out from BPM). The file is sent to SEND step one at a time.
Question : Filename of the source file is captured through user defined function.
Following is the code.
================
String v_result_time; //test Variable
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
if (key == null) { v_result_time= "Create Key Failed";}
else
{v_result_time= "Create Key worked";
String valueOld = conf.get(key);
v_result_time = valueOld;
return v_result_time;
The Mapping gives a runtime error in the BPM. This is a sporadic error.
I have selected the Adapter specific attribute(File name).
The BPM errors out sometimes? I am not sure if I am missing any setting. If I delete the work item and run the same scenario it works.
Question 1 : What is the cause of the above error?
Question 2 : Does BPM support Adapter specific attribute such as filename?
Kindly Advice.
Thanks,
Gowri

Hi Everyone,
Thanks for all the help.
DTN will not change the response filename to source filename. This option cannot be used. The correlation id is defined as response file name. Response filename is fixed for invoice file.
Here is the example.
For invoice file name HDTN20070430163110.TXT, response file received is nav1_2b5.rsp file. For HDTN20070430163314.TXT , response file is nav1_2b5.rsp
So my correlation id is dummy fixed value. I have known the fact that it is not possible to use context object filename.
Bhavesh - I have defined transform step for accessing filename using dynamic configuration. Following is the code used in mapping.
================
String v_result_time; //test Variable
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
if (key == null) { v_result_time= "Create Key Failed";}
else
{v_result_time= "Create Key worked";
String valueOld = conf.get(key);
v_result_time = valueOld;
return v_result_time;
====================================
BPM errors out sometime with following error

How should inheritance of permissions on AD behave?

Hi Forum members, I am not an AD expert in fact far from it. We have an in house software and we have used Active Directory to authenticate NT accounts to login to our application. In our application we can configure/setup AD groups in such a way that those
group members can get access to specific features and servers in our application. Please see my situation described below:-
I have the following config in place in my application:
LondonGroup (a user group, as present in AD) can manage HR Module of server LondonServer.
BirminghamGroup (as present in AD) can manage Finance Module of server BirminghamServer.
So when a user of AD group LondonGroup logs in to our application, he/she can manage the HR module on LondonServer. Similarly when an user of BirminghamGroup logs in, he/she can manage Finance module on BirminghamServer. That's all fine. The issue arises
when someone in AD makes BirminghamGroup a sub group of LondonGroup i.e. BirminghamGroup is a member of LondonGroup. When this is setup, when a user of AD group LondonGroup logs in to our application, he/she can manage the HR module on LondonServer -
which is still fine BUT when a user of BirminghamGroup logs in he/she can now access HR and Finance modules of both LondonServer and BirminghamServer!! This could be because we support inheritance feature of AD where a sub group should get all access permissions
from its parent group. But is this a problem? for e.g in our application we never set up BirminghamGroup to get access to HR module on LondonServer!
so my question is:
1) Is this expected behaviour from AD point of view? Is this because the Group setup on the AD is wrong (but there is nothing stopping users to do this)
2) Our application looks for the configured Groups and then traverses down the tree to locate the user and on the way additively gives access rights - is this a wrong implementation?
Sorry for the long story but any guidance will be highly appreciated.

Yes This is by design. There is nothing wrong in it. As Pierre mentioned it is called 'Group Nesting'.
I believe your application is following the concepts of 'Group Nesting' which is fine. It is behaving properly.
If you would like to not to have these sort of traversing in your application, you need to isolate the user accounts of being member in 'Nested Groups'.

Multiple inheritance in remote interfaces for EJB 3.0 session beans on Webl

Hi All,
We started migration from EJB 2.1(WLS 8.1) to EJB 3.0(WLS 10.3.2) and identified few serious problems. One of them is related with multiple business interfaces inheritance. I wrote simple example that presents point of the problem.
we have session bean AImpl:
+@Stateless(name="A")+
+@Remote({A.class})+
+@TransactionAttribute(TransactionAttributeType.REQUIRED)+
+public class AImpl implements A {+
+@Override+
+public void writeA() {+
System.out.println("A");
+}+
+@Override+
+public void writeB() {+
System.out.println("B");
+}+
+@Override+
+public void writeC() {+
System.out.println("C");
+}+
+}+
with remote interface A:
+@Remote+
+@JNDIName(A.JNDI_NAME)+
+public interface A extends B, C {+
public static String JNDI_NAME = "A_JNDI_NAME";
void writeA();
+}+
As you can see A extends B, and C. Definition of both interfaces is very simple:
+public interface B {+
void writeB();
+}+
+public interface C {+
void writeC();
+}+
Everything looks nice until we want to invoke some method on AImpl bean. For above implementation code:
A a = ctx.lookup(A. JNDI_NAME);
a.writeA();
a.writeB();
a.writeC();
writes down ”A \n B” and throws exception:
caused by: java.lang.NoSuchMethodException: pl.gov.arimr.zszik.bazowe.slowniki.ejb.A_vt0zts_AImpl_1032_WLStub.*writeC()*
at java.lang.Class.getMethod(Class.java:1605)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.getTargetMethod(RemoteBusinessIntfProxy.java:165)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.invoke(RemoteBusinessIntfProxy.java:57)
so.. in stub generated by WLS there is no method from interface C ! What more interesting after small change in interface A rely on change in interface implementation order from B, C to C, B (+public interface A extends C, B {+) server writes down only A and I have stack like below:
Caused by: java.lang.NoSuchMethodException: pl.gov.arimr.zszik.bazowe.slowniki.ejb.A_vt0zts_AImpl_1032_WLStub.*writeB()*
at java.lang.Class.getMethod(Class.java:1605)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.getTargetMethod(RemoteBusinessIntfProxy.java:165)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.invoke(RemoteBusinessIntfProxy.java:57)
After this experience I came up with suspicion that Weblogic 10.3 does not support inheritance from multiple interfaces in one “generation”. Instead of that it takes only the first interface from the list.
Does anybody have some experience with such a situation? maybe someone have an idea how to work around this problem?

This is Not Supported in WebLogic that the Remote Interface extends other Interfaces. Because Annotation Processor just looks up inside the implemented interface methods. The actual interface which is Implemented by the Bean Class. So the Methods declared inside the Interface B and Interface C will be ignored and will not be available as part of the generated Stubs. Thats why u are getting NoSuchMethodError.
You can even contact Oracle Support on this...there are 3-4 Cases on it. And the Solution is Work As Designed.
Workaround is : edit your interface A as following
Declare all the Business Methods only in the Remote Interface and not inside it's Super Interfaces.
Example:
@Stateless(name="A")
@Remote({A.class})
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public class AImpl implements A {
@Override
public void writeA() {
System.out.println("A");
@Override
public void writeB() {
System.out.println("B");
@Override
public void writeC() {
System.out.println("C");
@Remote
@JNDIName(A.JNDI_NAME)
public interface A extends B, C {
public static String JNDI_NAME = "A_JNDI_NAME";
void writeA();
void writeB();
void writeC();

Problem while configuring OSB External Resource in BPM Studio

Hi
I have just started using the BPM Studio 10.1.3. I want to invoke my Oracle Service Bus proxy services from one of the activities in the BPM Process flow.
I created an external resource of type Oracle Service Bus and while trying to catalogue the OSB Component I found that only my WSDL Web Service proxy services with http transport protocol are available to be catalogued. I couldnt find the proxy services of the type Messaging Service, Any SOAP Service, Any XML Service created on Oracle Service Bus.
Am I missing anything in the configuration or is it that BPM Studio does not support these protocols(jms,mq etc).
Also, in the Studio Reference there is a mention of Oracle BPM(native) transport that BPM supports for cataloguing OSB Components apart from http and https.
What is this protocol and how and where can i configure the same to help me catalogue the other OSB proxies?

What kind of XML concepts does XSU support?

What about other tags like choice nodes, sequences?
Does XSU also support inheritance and is it capable of recognizing multiple occuring elements? Or can all this achieved only via an XSLT transformation of the original document?
Thanks for your help,

Thanks for your help,
Bernhard I think you mean using XSU for data loading. Then, what XSU support is a format like:
<ROWSET>
<ROW>
<COLUMN_NAME>....</COLUMN_NAME>
</ROW>
</ROWSET>
Currently the XML SQL Utility (XSU) can only store data in a single table. Otherwise, you need help from XSLT or INSTEADOF Trigger.

Cons of using BPM

Hi All,
I know BPM is used when I need to implement a scenario which needs stateful processing. Also BPM is used when I need to go for a synchronous-asynchronous bridge. Also BPM supports good error handling.(Pls correct me if I was wrong any where)
When BPM provides me a lot of advantages why should i avoid using BPM as far as possible. Coz when I go through some previous threads a lot of experts advise not to go for BPM. Can you pls tell me why is that? Any docs where I can find cons of BPM would be of great help.
Thanks & Regards,
Jai Shankar.

Jai,
The mappings in XI get executerd on the Java Stack, whereas the BPM is executed in the Business Process EnNgine , which is a part of the ABAP stack.
So, a BPM has multiple calls between the JAVA and ABAP stack and causes a performance bottleneck
Like you mentioned BPM provides Stateful Message Processing and from what I have seen, normally during design stages of any XI Interface, when the choice is between whether to go for a BPM or not , the following questions are asked,
1. What is the number of times the interface will be run per day.
2. Can the interfaebe implmeneted without a BPM and if yes, then what is the approach and what is the disadvantage of avoiding a BPM.
ALso, http://help.sap.com/saphelp_nw04/helpdata/en/43/d92e428819da2ce10000000a1550b0/content.htm
Just check the Step types with low and high resource consumption and normally , the decision is based on the entire flow and the requirement of the interfaces.

Bhavesh

I want to change default language in BPM workflow when login to BPM workspace (ex: Vietnamese ...) and change properties default of Task, BPM supports multilanguage?
Does somebody know how can i do it ?
Thanks.

It is the same with Bpm. I will post the screen shot.
Edit: http://imgur.com/WoB2V
That shows that the same functionality in BPM workspace screen is missing. You can choose the browser or the LDAP it says. Like I said, you must have a parameter in your LDAP provider, setting the default language for seperate users, but I haven't seen this working yet.

Inheritance in EJBs

I am trying to find out if Weblogic supports functionality that TOPLink provides to
represent inheritance.
(http://www.webgain.com/products/toplink/mapping_workbench/demos/
check the "Using Advanced Descriptor Functions", "Inheritance").
I want to have a parent class which has multiple children (i.e. an Account class,
subclasses as Checking, Savings, Loan, etc.). These would all be stored in one database
table. A single 'findAccountsForCustomer' method could return a mixed collection
of the specific child objects.
Is this something available in a current version of Weblogic, or something planned
for the future? Or, is this something that requires a 3rd party mapping tool?

How does this differ from the second option I listed?
Thanks,
Bob

You can achieve inheritance using Entity Beans. Its not the simplest ofthings -
but its do-able. (Although I will admit I havent done this for aproduction application).

You would create an AccountBean - which is the base-class implementation.Your other
Checking, Savings, Loan Beans inherit from it. (Strictly they dont haveto - this
is only so you have implementation inheritance.)
Then, you would also create an AccountLocal - which is the base-classcomponent interface.
Your other CheckingLocal, SavingsLocal, LoanLocal Interfaces inherit fromit. (this
is so you get polymorphism at the client level)
Your PK classes must be the same all. (though, I forget why at the moment)
You need to create a home for each Bean (this makes sense - you have tohave a factory
that knows what its creating/finding).
You need to list all of them in the DDs. (the CMP mapping duplication is apain)

Its all a bit dicky doing it by hand. But if you can get your hands onWSAD4, it
will automate this all for you (Sadly, it only supports EJB1.1.... but youcan see
how it does it)
The thing to remember is that if they are in the same table (I wouldreconsider that
decision) then your findByPrimaryKey method will never be able todistinguish between
them.
The finders are a bit tricky - you need to do the aggregation of thesub-types.

EJB does not support inheritance. You are limited to standard Java's
inheritance capabilities.
If you want to use entity beans, you have the following two options:
1) Have a generic Account entity bean with an account type field (rather
than subclassing).
2) Use Java inheritance, set up an entity bean for each type (Savings,
Checking, etc.) and use a session facade. The findAccountsForCustomer()
method in the session facade will hit each entity bean type and combine
the
results.
I would probably go with the first option. You can use the Strategy
pattern
or something comparable to handle the implementation differences between
the
Account types.
