Object Life Cycle service Vs. Naming service

Hi,
In tuxedo CORBA, I find that Object Life Cycle service & Naming service have something
similar that the are both used to find object reference, aren't they?Then, I'm
interested in what make them diferrent in this action(find object reference) and
why to use one but not the other one?I can't be very clear from the docs.
Thanks and Regards
George

You are correct in that there is some overlap here (ask OMG about
this...). BEA historically recommended the use of the FactoryFinder
(BEA did not initially even support the Naming Service) since the whole
intent of the FactoryFinder was to "provide a naming service for Factory
objects" (rather than for instances). BEA believed that this was a
"best practices design pattern" to building scalable applications. Of
course, there is nothing preventing you from using the Naming Service to
do exactly the same thing and in fact, many existing applications were
written using the Naming Service in this way (since most other ORB
vendors did not implement the FactoryFinder) and as such, BEA added
support for the Naming Service.
Hope this helps,
Robert

Ho do we use Activity object of a Service Request object. I am trying to
create an Activity object for a existing Service Request object.
I am looking for some sample code.
I greatly appreciate your help.

drangineni, assuming you know the service requestid or externalId of the
Sr you are dealin gwith you would first set that value.
ServiceRequest1[] objSRList =new ServiceRequest1[1];
objSRList[0] = new ServiceRequest1();
objSRList[0].ServiceRequestId = <YourSRId>;
Then you create an array of activities and initialize the first one:
objSRList[0].ListOfActivity = new Activity[1];
objSRList[0].ListOfActivity[0] = new Activity();
Now set the data fields
objSRList[0].ListOfActivity[0].Subject ="My Subject";
objSRList[0].ListOfActivity[0].Description ="My Description";
objSRList[0].ListOfActivity[0].Display = "Task"; //valid values are either
"Task" or "Appointment"
Then call the ServiceREquestInsertOrUpdate method on the ServiceRequest
WebService and pass in the above variable.

Ah yes, I forgot you also need to specify a unquie Id for the activity.
It's kinda strange.
Try adding this:
ServiceRequest[0].ListOfActivity[ActivityLength].ActivityId = "DummyId";
//OD will overwrite this with a real Id
Or if you have a unquie ID for your Activities you can use:
ServiceRequest[0].ListOfActivity[ActivityLength].ExternalSystemId = <Your
Unique Value>;
Hope that helps,

Hi all,
I have a similar problem, but mine is returning a message that field
"Display" is required. Looking at this post and the documentation it is
obvious that Display is a required field, but my WSDL did not include a
field called "Display", so my proxy did not generate one.
I tried adding a field called Display to the WSDL and the proxy class, but
I get a different error... I figure I maybe cannot add it manually like
that - but I think the bigger problem is it is not part of the WSDL that
Siebel OD generates for me in my admin account.
On top of that Display is not shown in the list of fields for Activity
through the admin interface.. is it possible my account is bugged? Am I
missing something simple here? BigSlick, I see you mention a .Display in
your code sample so I thought you might understand what is wrong. Here is
my code (I am trying to add a activity to a lead).
Thanks for any insight into this!
private void InsertLeadActivity(Session session, NameValueCollection data,
string leadID)
try
if (blnDebug)
Response.Write("Setting up Activity ";
// instantiate the proxy service
Activity_Service.Activity activityProxy = new Activity_Service.Activity();
// set up the target URL
activityProxy.Url = session.GetURL();
activityProxy.CookieContainer = session.GetCookieContainer();
// set up input argument
ActivityNWS_Activity_Insert_Input input = new
ActivityNWS_Activity_Insert_Input();
input.ListOfActivity = new Activity1[1];
input.ListOfActivity[0] = new Activity1();
if (blnDebug)
Response.Write("Getting Data ";
// dg note: name value
// input.ListOfActivity[0].MrMrs = data["MrMrs"];
input.ListOfActivity[0].LeadId = leadID.ToString();
input.ListOfActivity[0].Description = DataToString(data);
input.ListOfActivity[0].Subject = "Website Submission Activity";
input.ListOfActivity[0].Priority = "3-Low";
//input.ListOfActivity[0].DueDate =
DateTime.Now.AddDays(7).ToShortDateString();
input.ListOfActivity[0].Owner = this.defaultLeadOwner;
input.ListOfActivity[0].Type = "Call";
//input.ListOfActivity[0].Display = "Task";
input.ListOfActivity[0].ActivityId = "DummyId";
input.ListOfActivity[0].ExternalSystemId = "web";
activityProxy.Activity_Insert(input);
catch (Exception exInsertActivity1)
if (blnDebug)
Response.Write(" Error inserting activity. " +
exInsertActivity1.ToString() + " ";

Figured it out.. the field "Display" is also known as "Activity"........
Here are some notes for other people.. good luck and feel free to write me
at raskawa-at-gmail-com if you want a code sample.
Some unpublished nice to knows for Siebel On Demand Activities....
In summary:
- .Activity is also known as Display in documentation and on the error
messages coming back from the WS. Also, it appears based on these boards
some people actually have a .Display field. Maybe different accounts
generate different WSDL's.... buggy.
- If a error message is thrown saying "Description is required" it really
means "Subject is required" (make sure .Subject has a value)
- If a error message is thrown complaining that ActionType is not right..
that is really .Type.. make sure it's lookup value is valid for the
dropdown values in your CRM OD system.
My code/values that worked..
input.ListOfActivity[0].LeadId = leadID.ToString();
input.ListOfActivity[0].Description = DataToString(data);
input.ListOfActivity[0].Subject = "Website Submission Activity";
input.ListOfActivity[0].Priority = "3-Low";
//input.ListOfActivity[0].DueDate =
DateTime.Now.AddDays(7).ToShortDateString();
input.ListOfActivity[0].Owner = this.defaultLeadOwner;
input.ListOfActivity[0].Type = "Call";
input.ListOfActivity[0].ActivityId = "DummyId";
input.ListOfActivity[0].ExternalSystemId = "web";
//input.ListOfActivity[0].Display = "Task"; //doesn't work
input.ListOfActivity[0].Activity = "Task"; //does work.

Hi,
This is surgientweb (under my own login now..)
Anyway, I wanted to add that I figured out that there are two ways to add
a Activity to a Lead. Via the Lead object (by getting a ListOfActivities)
OR by creating a Activity directly and just adding your "LeadID" to it (or
you can also add a "ContactID" to relate the activity to a Contact.)
Feel free to email me for a code example (raskawa....at....gmail)

Hi Stephane,
You can definitely read the categories using Tables in CRM. The logic is a bit complicated though.
Use the following steps to retrieve Categories using Std. CRM Tables:
1. Pass transaction GUID in field GUID of table CRMV_REPORT_SUBJ and get KATALOGART, CODEGRUPPE and CODE field values in lv_catalog, lv_codegrp and lv_code.
2. Now you need to concatenate these 3 fields values carefully like this:
CONCATENATE lv_catelog lv_codegrp ' ' lv_code into lv_category1.
Remember there are 4 spaces between lv_codegrp and lv_code.
3. Now pass this lv_category1 in field OBJEXT in table CRMC_ERMS_CAT_OK and get OBJGUID in field lv_objguid.
4. Pass this lv_objguid in field OBJ_GUID and LNK_TYPE = 'IS_CODE' in table CRMC_ERMS_CAT_LN and get value of CAT_GUID in lv_cat_guid.
5. Pass this lv_cat_guid in field CAT_GUID in table CRMC_ERMS_CAT_CA and get value of CAT_ID in field lv_cat_text.
Remember this lv_cat_text is the text value of your last level of category of transaction.
6. To get its upper cateogry level value, simply use table CRMC_ERMS_CAT_HI and get parent guid value and pass this as CAT_GUID again in table CRMC_ERMS_CAT_CA to get its text.
Alternatively, you can also use class method cl_crm_ml_category_util=>get_parse_all to get all levels of categories.
Hope this helps.
Thanks

Autorisation object for accepting service entry sheet in ML81n

Dear Sapiens,
What is the authorisation object for accepting service entry sheet in ML81n, here with my client some users are not getting the acceptance flag.
kindly guide.
Viji kantha

Hi,
I would like to share with you additional information on activities 75 and 76 to the different release objects:
To accept the service entry sheet the user has to have both
activities 75 and 76. Please note that it is not possible to accept an entry sheet
without activity 76.
Activity 76 means maintain service entry sheets,
Activity 75 means accept service entry sheets.
In order to accept the entry sheet, you must change into the
change mode. In order to change into the change mode, you
need the activity 76.
This activity 76 will be used in both creating and changing of the
entry sheet.
Regards,

The object in Directory Services has a class missing

Hello,
In Pending Events we have a few events for users (who are not yet managed by NSM for AD) with the following actions (and action states):
Evaluating Add Member (Evaluating user policy)
Create User (Getting policy for the user)
The last error message is: 92 : The object in Directory Services has a class or attribute mismatch and is not valid. Viewing the nsmengine-ad-(date).log file, I can see the following entries:
01 2014-04-02 08:55:20 3600 3 8003 1436 2908 cc::ds_ad::GetObjectListAsyncEx() - Called piDirSearch->GetNextRow(...), HRESULT = 80072030, Result = 15.
01 2014-04-02 08:55:20 3600 5 0008 1436 2908 PolicyTools::GetEffectivePolicies - Failed to get indirect group memberships for CN=<UserDetails>,DC=local. Result = 15.
A quick search for the error number indicates that the error (80072030) is that there is no such object on the server. All our DCs are Global Catalogs and I can confirm the users exist and are valid. Some of our groups do have a large number of members (up to 30,000).
Any idea what could be causing the issue and how to resolve it?
Thanks,
Jonathan

Which version of NSM are you using? Specifically, what Engine build are
you on? The easiest way to check this is in the Engine Status panel of
the NSM Admin client.

Live cycle service timeout

I have application which call adobe live cycle service such as assembler service,form data integration service,reader extension service etc. in my application we set timeout as 30 min. when i call large files for assembling and it looks like assembling service take more time to assemble. but after 30 min my application will time out but as i saw live cycle log it still process the old request.
Is there anyway to set timeout for assemble service or in general live cycle service other than pdfgeneration so that when my application timeout same time in server also that request should terminate

There are multiple timeouts that are relevant for a process. Orchestration Timeout should help here.

Life cycle of a web dynpro callable object

What is the life cycle of a web dynpro callable object.
Means when that Web dynpro callble object is used in a GP process which method of that component called first and what is the sequence of the method execution in that.
Can anyone please explain me.

Sorry ritu there was one mistake in the above two replies.
The actual execution of the methods when a callable objects is get executed is as following
1.component controller's init() method
2. interface's init() method
3.view's init() method.
4.interface's execute() method
5.view's wDoModifyView() method.
If you want to change anything on your view according to the change in the interfac's execute method.
Then you have to do that coding in view's wDoModifyView() method.

shanto aloor.

Transient Object in Appliaction Service

Hello *,
I have three Entity services:
one for product data from PLM -> external,
one for price data from SD -> external,
one for additional data -> local.
These three services I'd like to aggregate in one application service (PriceObject) which is remote enabled and accessible as a Web Service.
When my GUI or any other application wants to have a PriceObject, they call my PriceObjectService with material data (key) as input and get a complete PriceObject (including data from all three entity services).
Normally, if I add entity services as dependencies to my application service it can just return one of the entity services in operations tab.
So I think my question is:
How can I realize a transient object as application service which aggregates entity services and returns the aggregation?
Thanks in advance and best regards
Joschi

Hello Joachim,
Unfortunately there is no way to create a custom "Aggregate" output Data Structure which would hold these 3 Entity Services. You can create custom data structures, but there are no options for Entity types. You should be able to create an output Data Structure that holds 3 object references, but then the client would have to look up each entity by it's service interface.
Did you build Entity relationships for all 3 of these Entities? If so, then you can return one from your PriceObject and then the client can navigate to the other 2 through the generated getEntity() methods.
Maybe the best option would be to create a complex Data Structure which basically mimics the aggregate structure of your three Entities. In your PriceObject application service method, you would have to copy over the data from the 3 Entities into the new Transient data structure.
Regards,
Austin.

Proxy object from "Enterprise Service" in SE80 is not available?

Hi all,
We are currently working on SAP CRM, the component version is SAP CRM ABAP 6.0 (SAP CRM 2007).
Previously the component version was SAP CRM 5.0, so as you can understand it has been upgraded from 5.0 to 6.0.
Now when we use the transaction code SE80 and try to create a "proxy object" from "Enterprise Service" in the context menu, this feature is no more available.
Initially it was available in SAP CRM 5.0.
Can anyone tell me What is missing in the current version SAP CRM ABAP 6.0 ? Do we need to install any Add-on?

Yes...I got it...

Object type for service notification?

Hi guys,
In workflow what is the object type to create service notification (IW51). How can I find it?

The object type for service notifications is BUS2080. You can find it via transaction SWO1 - use the search help on the Object/Interface field. You can also use the Business object repository (Browser) button on SWO1.

Could not generate stub objects for web service invocation in ColdFusion

I was able to call the services on the development box - windows server without any problem at all, everything was working fine but the moment i uploaded to a linux box production server I get this error. "Could not generate stub objects for web service invocation in ColdFusion"
What could be the cause of this problem, i have googled a lot but no solution yet any ideas.

Let me make it simple:
1. Server A is our development server.- hosted inhouse with coldfusion installed.
2. Server B is our production server - a linux server with coldfusion installed hosted on the internet
3. Server C is a third party server containing the webservice - this is a windows server with .net
coldfusion is installed on Server A, the code works here and can connect to server C without any problem. It gets the required respone
but when the code was uploaded to server c it gives the error when we run it.
now i tried just a simple code which works fine on server A below:
<cfinvoke webservice="http://www.webservicex.net/CurrencyConvertor.asmx?WSDL" method="ConversionRate" returnvariable="ConversionRateResult">
 <cfinvokeargument name="FromCurrency" value="EUR" />
 <cfinvokeargument name="ToCurrency" value="USD" />
</cfinvoke>
<cfdump var="#ConversionRateResult#" />
But when i uploaded it to server C: it returns the error
Cannot generate stub objects for web service invocation.
Name: http://www.webservicex.net/CurrencyConvertor.asmx?WSDL. WSDL: http://www.webservicex.net/CurrencyConvertor.asmx?WSDL. java.io.FileNotFoundException: /opt/coldfusion8/stubs/WS728929035/NET/webserviceX/www/Currency.java (No such file or directory) It is recommended that you use a web browser to retrieve and examine the requested WSDL document to ensure it is correct. If the requested WSDL document cannot be retrieved or is dynamically generated, it is likely that the target web service has programming errors.
The error occurred in /home/works/public_html/currency.cfm: line 7
5 : <cfinvokeargument name="FromCurrency" value="EUR" />
6 :
7 : <cfinvokeargument name="ToCurrency" value="USD" />
8 :
9 : </cfinvoke>
Now if you try the preceeding code on a windows environment it works fine but the moment you put in the in the linux environment it generates this error
I feel that the error may actually be :
java.io.FileNotFoundException: /opt/coldfusion8/stubs/WS728929035/NET/webserviceX/www/Currency.java (No such file or directory)
but i am clueless as to what to do next
Ok so I tried the wget command on the linux
this is what i got
-bash-3.2# wget http://www.webservicesx.net/CurrencyConvertor.asmx?WDSL

How to pass objects between servlet services

I wanted to pass an object from one service to another service and that object must be visible only for these two services. I don't want to use session.setAttribute or session.getAttribute to do this. When I use request.setAttribute and request.getAttribute methods not helping me to do this. Is there a way to do this?
Between, how these request.setAttribute and request.getAttribute methods useful?
regds
-raju

Actually, I set attribute in one of the service
methods. Within that service method a form will be
there. After pressing submit button in that form, the
other service will be called. Does it mean that both
the services are not in the same request scope, even
if they are in the same servlet?They are on different request scopes. Each time the user clicks a link, they make a request to the server. The server processes the request creates a response and send that response back to the client. Once the response it sent (and finished being sent) the request is done with, and anything is request scope goes out of scope. When the user clicks the submit button, a NEW request (and request scope) is made to handle that ...
Your best bet is to use a session here. It is the easiest way to maintain state between requests. That is what the session is designed for.

Component life cycle doesn't apply to objects created w/in ActionScript block??

i don't understand why init() is never called. typically one can initialize variables in the constructor, but since this is mxml, the constructor is automatically created for us and the programmer seems to have no access or override privileges. so what to do?? am i failing to grasp some aspect of the component life cycle process?? how should i go about initializing properties??

NOTE: the code above might seem a little ridiculous, but that's b/c i reduced it down. imagine a baseComponent and derivedComponent where the myString has a default value in the base case and needs to be overridden in the derived case. appreciate any insights and thanks,

Thanks Corey and Mike
I suppose I should have been more aware about when the initialize event gets dispatched -- the concept just wasn't registering for me and I was totally miffed about how to initialize variables on construction.
Do you have to initialize before the instance is added to the display list?
Yes, I was mixing both mxml and AS classes and the derived classes had no display objects to attach to the stage (they were mostly classes made to modify run time behavior). You can check out my previous post, which gives the code for where or why this might be needed.
I ended up initializing mxml class variables during construction in the following way:
------------------------------ classes/BaseClass.as ------------------------------
package classes
public class BaseClass
 public var myString:String = "hello, world";
 public function BaseClass() {
 init();
 protected function init():void {
 // intentionally left empty
------------------------------ classes/DerivedClassI.mxml ------------------------------
<?xml version="1.0" encoding="utf-8"?>
<classes:BaseClass xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/halo"
 xmlns:classes="classes.*"
 myString="hello, cruel world!">
</classes:BaseClass>
------------------------------ classes/DerivedClassII.mxml ------------------------------
<?xml version="1.0" encoding="utf-8"?>
<classes:BaseClass xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/halo"
 xmlns:classes="classes.*">
<fx:Script>
 <![CDATA[
 override protected function init() : void {
 myString = "hello, cruel cruel world!";
 ]]>
</fx:Script>
</classes:BaseClass>
------------------------------- Main.mxml ------------------------------
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/halo">
<fx:Script>
 <![CDATA[
 import classes.*;
 import mx.collections.ArrayCollection;
 [Bindable] private var list:ArrayCollection = new ArrayCollection( [
 new BaseClass(),
 new DerivedClassI(),
