Dynamic service binding in ESB

Hi,
I am trying to do dynamic binding in ESB (using service registry key) and facing the following issue:
1>I have added the uddi Inquiry url in the esb_config.ini:
uddiInquiryURL=http://ossi-1042.idc.oracle.com:8888/registry/uddi/inquiry/
2>In the ESB, I am invoking BPEL through soap service. There are 2 BPEL processes, say B1 and B2. I am giving the wsdl location of B1, and in the endpoint properties i am adding the registry key of B2 (so that I can find out if the registry key property is working):
<endpointProperties>
<property name="registryServiceKey" value="uddi:797f8d80-fbbf-11dc-a4bb-27e52611a4ba"/>
</endpointProperties>
When I run the instance, always B1 is getting invoked, proving that the registry key is not being used and thus dynamic service binding is happening.
Kindly help me out in this.
Thanks and regards,
Pavan

I tried applying the patch, but it gives the following error:
OPatch detects your platform as 207 while this patch 6133448 supports platforms:
0 (Generic Platform)
This patch is not suitable for this operating system.
Please contact support for the correct patch.
ERROR: OPatch failed during pre-reqs check.
OPatch returns with error code = 150
I downloaded for the OS I am on, but always the generic patch downloads; i guess this generic one should work for all platforms. Opatch version is 1.0.0.0.56.

Dynamic context binding in web dynpro alv

I use dynamic context binding (see code below to show and edit the ALV table.
'DB_TABLE' is a tranparent table. It works fine.
But now this table should be expanded with additional fields which are only known at runtime and could be different from case to case.
How can I get these fields in the context dynamically?
DATA:
        rootnode_info TYPE REF TO if_wd_context_node_info,
        dyn_node      TYPE REF TO if_wd_context_node,
        tablename   TYPE string.
rootnode_info = wd_context->get_node_info( ).
tablename = 'DB_TABLE'.
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
    parent_info = rootnode_info
    node_name = tablename
    structure_name = tablename
    is_multiple = abap_true ).
DATA:
        stru_tab TYPE REF TO data.
FIELD-SYMBOLS: <tab> TYPE table.
CREATE DATA stru_tab TYPE TABLE OF (tablename).
ASSIGN stru_tab->* TO <tab>.
SELECT * FROM (tablename) INTO CORRESPONDING FIELDS OF TABLE <tab>.
dyn_node = wd_context->get_child_node( name = tablename ).
dyn_node->bind_table( <tab> ).

You should create a structure dynamically and use this as the context structure. See the coding below, where a structure is created, which contains CARRID and CONNID.
DATA: node_info type ref to if_wd_context_node_info,
      struct_type TYPE REF TO cl_abap_structdescr,
      table_type type ref to cl_abap_tabledescr,
      comp_tab    TYPE cl_abap_structdescr=>component_table,
      comp        LIKE LINE OF comp_tab,
      my_table    type ref to data,
      my_row      type ref to data.
field-symbols: <table> type table,
                 <row> type data,
                 <flight> type sflight.
* build a structure description from the list of single fields
comp-name = 'CARRID'.
comp-type ?= cl_abap_datadescr=>describe_by_name( 'S_CARR_ID' ).
APPEND comp TO comp_tab.
comp-name = 'CONNID'.
comp-type ?= cl_abap_datadescr=>describe_by_name( 'S_CONN_ID' ).
APPEND comp TO comp_tab.
* note this structure contains the fields "CONNID" and "CARRID"
struct_type = cl_abap_structdescr=>create( comp_tab ).
* now the nodeinfo is created
node_info = wd_context->get_node_info( ).
node_info = node_info->add_new_child_node(
    name                         = 'MY_NODE'
    IS_MANDATORY                 = ABAP_true
    IS_MULTIPLE                  = ABAP_true
    STATIC_ELEMENT_RTTI          = struct_type
    IS_STATIC                    = ABAP_false
* fill new node;
data: l_node type ref to if_wd_context_node,
        l_flight type STANDARD TABLE OF sflight.
l_node = wd_context->get_child_node( 'MY_NODE' ).
l_flight = wd_assist->get_flights( ).
* if you could create a local data type, would be fine, but if you have to do it dynamically ...
struct_type = node_info->GET_STATIC_ATTRIBUTES_TYPE( ).
* create tabledescriptor from structdescription (standard table, no keys)
table_type = cl_abap_tabledescr=>create( p_line_type = struct_type ).
create data my_table type handle table_type.
assign my_table->* to <table>.
loop at l_flight assigning <flight>.
    create data my_row type handle struct_type.
    assign my_row->* to <row>.
    move-corresponding <flight> to <row>.
    append <row> to <table>.
endloop.
l_node->bind_table( <table> ).

OSB Dynamic service call or dynamic route and transactions

Hello,
I've got the following problem in my OSB architecture for asynchronous incomming services.
OSB version is 10.3.1
ConnectionFactory is XA
Problem domain:
Dynamic service call or dynamic route within transaction boundary
Elements within transaction:
1.     JMS Queue ->
2.     Upper Proxy Service (De-queue) ->
3.     Lower Proxy Service (Canonical Service) ->
4.     Business Service (Data Service) ->
5.     Database Adapter->
6.     Database
Dynamic element
Upper Proxy Service (De-Queue) must be able to determine which Lower Proxy Service (Canonical Service) has to be called on the basis of the message taken from the JMS Queue without losing the transaction (this doesn’t work yet).
Already tried possible solutions:
•     Make a service call dynamic by setting the $inbound name attribute. This results in a this property is read-only error.
•     Use a Dynamic route instead of a service-call. This results in a loss of transaction. The message is deleted from the Queue without taking failure or success into account.
•     Use a Dynamic route with a quality of service set to exactly once in the header. This seems to be ignored, results in a loss of transaction.
•     Use a Dynamic route with an explicit reply with failure for errors. Results in a loss of transaction.
•     Use a Dynamic Publish. This doesn’t fit the required flow because it has no response.
I hope someone can shed some light on this because I'm at a total loss. I found some references in the forum to what seems to be the same problem but without definite answers. A work-around is also a viable answer.
Regards,
Bas Mul

Hi,
I'll try to clarify.
Upper proxy dequeues a message.
Depending on a value of a specific tag within the message a canonical proxy service (out of 5 at the moment but this numer could increase) has to be called (and be dynamic transform transformed to the format of the specific canonical).
The canonical service must then pass the message to a database adaper's business service which is responsible for the database insert/update/read.
If something in the chain from dequeue to database action goes wrong the message may not dissapear from the queue.
Somehow a dynamic route in the message flow between dequeue proxy and canonical proxy breaks the transaction.

Dynamic value binding for InputTextField - Expression within an expression

Hi,
I have this requirement where I have to use an EL expression's output as a bean's property in the value attribute of a InputTextField. E.g.
          <h:dataTable value="#{entity.formats}" var="field">
               <h:column>
                    <h:outputLabel value="#{field.shortDesr}"/>
               </h:column>
               <h:column>
                    <h:inputText value="#{*entity."+#{field.shortDesr}+*"}"/>
               </h:column>
          </h:dataTable>
The JSF page will be a generic one so the fields within a form will be dynamic and will be formed at run-time. Since the exact bean property(entity in the code above) for a particular field is not known before, it needs to be dynamicaly built
To give more clarity. In the following snippet, i know that entity is the bean to be used but which property(XXX) the text field has to be bound is not known and needs to be assigned at run-time.
<h:inputText value="#{entity.*XXX*"/>
Is this possible? Are there any direct JSF solution or work arounds for it? Appreciate your inputs.
Thanks
Ranjith

A: Dynamic value binding for InputTextField - Expression within an expression

Hi BaluSC,
Your solution is totally acceptable. But I was also looking for something that can make possible direct binding to the bean properties without going through a Map.
In the meantime, I worked around the problem by not using the DataTable. Instead I loop the collection and add the Form elements programatically (code given below). With this I am able to achieve the desired effect of binding directly to the bean's property. But I am hitting another problem now, On submit the form Seam throws up 'No active conversational context" error while binding the #{sdmManager.grid} attribute. Now, I am trying to figure out how to come across it.
JSF
     <h:panelGrid columns="2" binding="#{sdmManager.grid}">
</h:panelGrid>
Bean code
     public HtmlPanelGrid getGrid(){
     grid = new HtmlPanelGrid();
     List<UIComponent> children = grid.getChildren();
     Collection<FieldFormatData> formats = dataManager.getFieldFormatData();
     for(FieldFormatData format:formats){
          HtmlOutputLabel outputLabel = new HtmlOutputLabel();
          outputLabel.setValue(format.getShortDesr());
          children.add(outputLabel);
          HtmlInputText inputText = new HtmlInputText();
          inputText.setSize(10);
          inputText.setMaxlength(10);
          System.out.println("Binding ................................... " + format.getEntityField());
          inputText.setValueBinding("value", FacesContext.getCurrentInstance().getApplication().createValueBinding("#{entity."+format.getEntityField()+"}"));
          children.add(inputText);
     return grid;

All System Groups/Services disappeared in ESB Control after redeploy

Hi all,
SHORT: all entries in the "Services" pane of the ESB control have suddenly disappeared.
DETAILED: After a few successful cycles of changing/deploying/running and viewing instances of my ESB service via the ESB control, I redeployed and run the application. The previously successful test I ran did not get a reply from the service. Obviously, this could be either due to me breaking the service with the last change or because of some crash in the SOA Suite. So I tried to get more information via the ESB console but all System Groups and Services have disappeared - the left "Services" pane is empty.
Restarting the SOA Suite does not fix this.
==> any suggestions on what could have happened and how to resolve this without reinstall ? (we don't want this to happen in production, do we ;-) ?)

two collegues of mine ran into a similiar problem. Their ESB console seemed empty as well.Until one of them let the console open for about 10 minutes and the services/system re-appeared.
Indicating that when the services do not show up could also be caused by a serious performance glitch or the services are calling external systems which time out.
Another option is to wait for a few minutes and see if your services etc show up again.
I don't know where this performance degradation is coming from though. The only thing I noticed is that the ORAESB schema ( advanced install ) is installing al of its objects in the USERS tablespace and that most ( almost all ) tables do not have any indexes / pk / fk's on them.
Maybe one or two indexes could speed up the ESB repository considerably.
Dave, In the upcoming 10.1.3.3 release is the repository in any way altered? Default tablespace? PK/FK and/or extra indices on certain tables/columns?

Failure upon calling web service on the ESB deployed from jDeveloper

Hello!
I've created a database adapter and a routing service that calls the database adapter. When registering the services on the ESB, I get error when I try to call it, as the Wsdl references a wsdl file on http://localhost:8888...... As I see it, it should refer to in on the same server as the esb (soa suite) runs? I think this might be a deployment issue in jDeveloper, maybe ant? Any clue on this?
brgds, Paul Jørstad

Thank you very much for you reply!
But I do not get any further.. In the ESB control, the Soap Endpoint URI still says:
SOAP Endpoint URI
http://localhost:8888/event/xal/rs_product_p_get_complete_bom_flat
And in my wsdl file:
<soap:address location="http://oslsoad1/event/xal/rs_product_p_get_complete_bom_flat"/>
I've tried to de-register, and register the service.

Dynamic Data Binding at runtime

For future applications, flexibility will be an important feature. One of the biggest drawbacks of forms is/was, on my opinion, not being able to create new items at runtime.
JClient will easily overcome this restriction. But how about data binding ?
Imagine the following situation: We've got a VO "order" with the "custname" incorporated as lookup data. At runtime, the user decides that she needs to see the "custloc" as well (put an additional JTextField into some whitespace on his panel). As I understand it is possible to build a view link to tie an instance of the VO "customer" to the "order" (I'd prefer that over adapting the query statement of "order" at runtime). But how can I create the new iterator binding and control binding needed to populate the dynamically created attributes with the data from "customer"? And, further on, how will I be able to make the changed configuration of my panel persistent, let's say into the DB ? Or does the data binding concept of 10g just not cover this requirement?

Dynamic partnerlink binding problem

I am trying to create a dynamic partnerlink as in http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html .
When I am trying to create this with LoanService.wsdl, it works correctly for me but when I try to create it for my own service, it is showing up some errors which I fail to understand.
I have three services service1,service2,service3.
I have created another web service called CallPartnerService in which I have imported the service.wsdl to create the partnerlink. After that I am following the instructions in the cookbook to create the create the partner reference variable, copy the partnerReference variable into the Service partner link etc
However, when I run it, I get the following error on invoking the partner service.
Cannot find binding operation.
in WSDL located at "file:/D:/product/10.1.3.1/OracleAS_1/bpel/domains/default/tmp/.bpel_CallPartnerService_1.0_a8cb48601311c51027d61ee288d499df.tmp/Service.wsdl", cannot find a binding operation of "process", portType "{http://xmlns.oracle.com/}Service"

Service binded on only one ethernet interface

Hello everyone.
I am stuck with a little problem on Snow Leopard Server.
I want to open an auxiliary ssh server on the port 443, so I duplicated the /System/Library/LaunchDaemons/sshh.plist
I modified the label with a new name and set the socketName to https (443)
After loading and starting the services I have the following pb:
on 127.0.0.1:443 the server is working fine.
on my LAN interface (en1 or en2)10.0.0.1:443 the server is working fine
on my WAN interface (en0) 82.XX.XX.XX:443 the server cannot be reached...
the firewall is setted to let pass everything and I am sure of any NAT.
even if I try an "ssh 82.XXX.XXX.XXX -p 443" on the server itself, I have no answer.
Any idea?
Best Regards

Construct your MulticastSocket with not just a port number but with a SocketAddress as the bind address, containing the port number and a non-null InetAddress representing the local IP address to bind to, i.e. the network interface to listen at. If the InetAddress is null or absent the socket listens at all local network interfaces.
MulticastSocket.setNetworkInterface() controls which interface is used when sending.
If you are doing all this, so as to restrict multicasting, you also need to make sure to join and leave your multicast group(s) via the same network interface(s) as above.

What's the meaning of a yellow DB-Adapter service in an ESB Instance?

Hi Forum,
I have implemented a really small ESB routing application, taking 3 Values, which will be written to a database using a routing service and a DB-Adapter. When calling this service via URI of the local endpoint (at the definition tab of ESB Control) everything works fine so far.
Next I tried to invoke this service from a BPEL process. But all I got was a yellow marked DB-Adapter in the ESB instance. This is accompanied by a R tag on the adapter. The details tab states that a rollback has been done because of an error "undefined" on a non transactional endpoint.
By the way, there is no error tab displayed in ESB Control and moreover no BPEL instance is logged. I asume that is a result of the rollback. So there is pretty few information on what has happened.
Unfortunately I couldn't find anything of value on the web dealing with non transactional endpoints.
Has anyone got a clue, what the reason for this strange behavior could be?
TIA,
Marco

Hi James,
thanks a lot for your answer. You've been totally right, it was a error in payload. Actually, after fiddling about with no success to get it right, I ended up with no ESB instance trace at all :-(
So I decided to restart the server and guess what, everything looked nice. The instance came up with tracking information and error log showing that the payload was incomplete.
And even the main problem of being unable to deploy a BPEL-Process because of an undefined partner link type (which I couldn't follow as the PLT was enclosed in the wsdl of the ESB service and that led me to designing a small repro case) vanished into thin air.
This SOA-Suite seems to be a sort of weird. At the moment I can't figure out how to successfully run a real-life project using this technology :-(
Working on a research project now, I hope to be getting more experienced before it gets down to business.
Cheers
Marco

Dynamic element binding between XML based PDF form and WDA context

Hi Experts,
I am working on a XML based interactive form.There is a table node in the XML interface which generated by WDA context, and binding on a subform in the PDF form.
I tried to add instances to the subform using javascript. Unfortunately, I can not get the internal table in WDA.
If I initialize the table to 10 lines in WDA , and then add 5 line to it in PDF, when I submit the PDF, I can only get 10 lines in the WDA framework. It seems that the element which is create dynamically can not be past to the interface.
Could you tell me why? And is there any other better solution? I just want build a table in PDF form in runtime and pass it to WDA context.
Thanks a lot!
Best Regards,
Guo Guo Qing

Hi Thomas,
Thank you for your reply.
I think the performance will be a problem if I create the elment in WDA using submit event. I need to create hundreds of record dynamically. I must find some way to reduce the communication between the WDA and PDF form. Maybe I can set a container with a number of elements before the PDF output. Do you have some better ideas?
Best Regards,
Guo Guo Qing
