InitialContext() and lookup

Context ctx = new InitialContext();
URL program= (URL)ctx.lookup("url/program");
Where does the ctx.lookup search for the "url/program"?
--My guessing would be from a system file such as abc.xml. If this is correct, I have questions about it:
For IBM RAD, it may setup its system file as resource.xml, while for Oracle JDeveloper, it may set up as application.xml, etc. Now how does the ctx.lookup know where to look up the system file? (I mean, this system file can be different for each IDE manufacturer).
If my understanding is wrong, what should be the right explanation?
Thanks
Scott

The javadoc of Context and InitialContext explains quite well these things.

Import of Main and Lookup table in a single Map

Hey Guys,
I am developing a Proof of Concept to Import Main and Lookup-Flat in a single Import Map (by using a single excel file).
Below is my Table structure:
Main Table: Customer
--->Customer_Number (Text,Unique Field, Display Field)
--->Sales_Area (Lookup Flat)
Lookup Table: Sales_Area
Sales_Area_ID (Text,Unique Field,Display Field)
Sales_Area_Desc (Text,Display Field).
The import File (excel) has below attributes:
Customer_Number,Sales_Area_ID,Sales_Area_Desc.
When i start both Main Table and Lookup tables are empty (there is no data in Data Manager for either of the tables)
Now in the Import Map, i selected source as the excel file and target as the Main table.
I did mapping of Customer_Number as usual after that I created a compound field for Sales_Area_ID+ Sales_Area_Desc and did the mapping of this compound field. then did the mapping for Sales_Area_ID and Sales_Area_Desc.
Now since there is no data in lookup table, i select the "Add" button in the "Value Mapping" section. when i execute this map, it works perfectly and data is loaded in both the Main table and lookup table but if a new value comes in the excel(a value which does not yet exist in lookup table), the map fails, when i open it , it says that i need to redo the Value Mapping, again i click on "Add" button and it starts working. So basically the Import Map fails whenever i get a value in excel which does not yet exist in Lookup table.
Now my question is, is there a way to automate my import map, i thought clicking on "Add" button will take care of all the lookup values which are not already present.
Can anyone please help me in this regard.
Thanks
Saif

Hi Saif,
You can try the following option.
Right click on the lookup filed/compound filed in destination fields, and select the option 'SET MDIS Unmapped Value Handling' as 'ADD'.
Cheers,
Cherry.

Lookup Flat Table and Lookup Qualifier Table

Hi,
Can any body confirm that if I will change the type of lookup-flat type field to lookup-qualifier type field. But the structure of Lookup Flat table and Lookup Qualifier table will be the same then the Java code written to populate the lookup-flat type field will work without any changes with its new type (lookup-qualifier).
Right now when I run the code after the above said changes, no error comes but no values is assigned to that field.
Another way to ask this question, can a simple Qualifier Lookup table(without having any qualifier type field) be used as like Lookup flat table.
I would appreciate if any body can help me in this regard ASAP.
Regards
Shahid Nadeem

Hi Alok,
I think this Qualifier importing after main table import is quite trickier that you estimate.
1)Map all the fields of qualified table with source fields whther they are qualifiers or non-qulaifiers.
- we will only be able to view the Non Qualifier field in the qualified table.
2)Now the main step is when you finish all field and value mapping there will be also a Target field name on your qualified table with values of display field. this field must be mapped to a source field to import qualified table. do value mapping also.
- This target field is the linkup field you are talking abot i feel, and it is viewed only in the main table and, as i have only on one non- qualifier this will not be a combination of any display fields.
3)I am not abl eto see the Non -Qualifier in my main table
So how do i proceed.
Kindly guide
Thanks

Intial Context and lookup tunning ?

Doing a inital context and lookup for an EJB for every user in my webapp takes a lot
of time, is there any tunning that can be done,can i get the Home Handle and put
it in Application scope and have subsequent users reuse it ?
Any examples or ideas will be appreciated.
Thanks
Joe

The caveat is you still need to get the initial context per user per request
(but you can cache the home handle.) The reason is that the WLS security
context is allocated on a per-thread basis, and since each request can
be served from different threads, this context needs to be refreshed on
each request.

Differenct between Lookup Error Output and Lookup No Match Output

Hi All
I'm new in SSIS and reading book for SSIS and unable to understand the difference between Lookup Error Output and Lookup No Match Output in Lookup transformation. Are these terms same or is there any difference between them ?. Please guide
Thanks
Regards
Muz

Nope. Error output is more generic ie any errors happening inside lookup can be redirected to error output by default. This includes lookup match failures as well as data conversion error, truncation error etc. Upto SSIS 2005 this was the only output available
in addition to match output inside lookup so if you want to capture unmatched rows you had to redirect them to error output itself.
But from SSIS 2008 onwards they've introduced one more output called no match output. This gives you ability to redirect only no matched rows through no match output so that you'll be able to distinguish between unmatched rows and other error rows.
You can configure this option inside Specify how to handle rows with no matching entries option in Lookup Editor. You can choose Ignore Failure,
Redirect rows to no match output,Redirect rows to error output etc as options
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

Questions on InitialContext and replica-aware stub caching

Hi All,
We have a cluster and deployed with some stateless ejb session beans. Currently we only cached the InitialContext object in the client code, and I have several questions:
1. in the current case, if we call lookup() to get a replica-aware stub, which server will return the stub object, the same server we get the InitialContext, or it will load balanced to other servers every time we call the lookup method?
2. should we just cache the stub? is it thread safe? if it is, how does the stub handle concurrent requests from the client threads? in parallels or in sequence?
One more question, when we call new InitialContext(), it will take a long time before it can return a timeout exception if the servers are not reachable, how can we set a timeout for this case?

You can set the timeout value programatically by using the

Hi, I tried setting the parameters before, but it only works for stub lookup and ejb call timeout, not for the creation of InitialContext. And any idea for my 2nd question?

InitialContext and PROVIDER_URL

I'm creating an InitialContext in a server-side object, relying on the WebLogic Server
to use the local naming service. This works as expected. However, once created,
I would like to determine the URL and initial context factory for the local naming
service. When the following code is executed:
InitialContext myCtx = new InitialContext();
ht = myCtx.getEnvironment();
myContext = (String)ht.get(Context.INITIAL_CONTEXT_FACTORY);
myServer = (String)ht.get(Context.PROVIDER_URL);
if(myServer == null)
myServer = (String)ht.get(weblogic.jndi.WLContext.PROVIDER_RJVM);
..the initial context factory is returned as expected from the environment hashtable,
but both PROVIDER_URL and PROVIDER_RJVM are null. Is there any way to determine
what the correct URL for the local naming service is? (Assuming that there is no
guarantee that it is at localhost:7001)
Thanks in advance,
Mike

I figured this out myself . A bug (6089084) was reported and closed as Not-A-Bug. Sun App server has a workaround on it. Instead of using InitialContext() with programmatically specified properties, specify the ejb-name/jndi-name binding in ejb descriptor file (with jndiname format : 'corbaname:iiop:<host>:<iiop port>#<Bean's JNDI name>'), create an InitialContext without any added properties, and use 'java:comp/env/<ejb-name>' for lookup.

Some basic questions about rmi registry context "bind" and "lookup"

We have more processing to do than can be accomplished with a single computer. To solve the problem I've implemented a distributed computing solution using RMI. (The first time I saw RMI was about 2 weeks ago, so please bear with me!)
The implementation is a proof of concept not a fully fleshed out system. I have one "Workunit Distributor" computer and any number of "Data Processor" computers all on the same lan segment. "Workunit Distributor" and "Data Processor" computers are both RMI client and server to each other. The "Data Processor" computers are given the ip address and name of the "Data Distributor" on the commandline when they start. They communicate their willingness to receive and process a workunit to the ""Workunit Distributor" via a RMI call. Work units are sent to available "DataProcessors" and results are eventually returned to the "WorkunitDistributor" (minutes or hours later). The model program works quite well, and appears to be capable of doing the processing we need to get done.
But now that it seems viable, I've been asked to make it a little more scalable, flexible and self configuring. In particular, instead of one "Workunit Distributor", any number of "Workunit Distributors" should be allowed to show up or disappear from the lan at any time and the system should continue to function. I've worked out a good scheme for how this can be done, but I have a couple of questions about the RMI registry (registries?). I'm trying to keep from implementing some functionality that may already be available as a library or subsystem.
With my current model design, each computer binds to its own registry with a unique name. For instance:
CRDataProcessorImpl crdpi = new CRDataProcessorImpl(svr);
Context crDataProcessingContext = new InitialContext();
crDataProcessingContext.bind("rmi:"+hostName, crdpi);
Currently the "Data Processors" get the info they need for a Context lookup() of the one and only "Workunit Distributor" from the commandline. And the info the "Workunit Distributor" needs to do a Context lookup() of a "DataProcessor" is passed to it from each "DataProcessor" via a RMI call.
But in the newer (yet to be implemented) scheme where any and all "Workunit Distributors" show up and disappear whenever they feel like, the naming bootstrapping scheme described above won't work.
I can imagine a few ways of solving this problem. For instance, having "Workunit Distributors" multicast their contact information on the lan and have a worker thread on each "Data Processor" keep track of the naming information that was multicast. Another alternative (more organized, but more complex) might be to have a dedicated host with a "well known" address and port that "Workunit Distributors" and "Data Processors" could all go to, to register or look up at an application level. Sort of a "domain name service" for RMI. But both these schemes look like a lot of work to implement , debug and maintain.
The BEST thing would be if there was one plain vanilla RMI registry that was usable by all RMI enabled computers instead of having each computer have its own local name registry. In volume 2 of the Core Java2 book it says that every registry must be local. I'm only hoping there's been progress since the book was published and now a central rmi registry is available.
If you have any ideas about this I'd like to hear what you know.
Thanks in advance for any advice.
Lenny Wintfeld
ps - I don't believe web services, as full featured as it is, is a useful alternative. I'm moving 100's (in the future possibly 1000's) of megabytes back an forth for processing.

The local bind/rebind/unbind restriction is still there and it will always be there.
I would look at
(a) RMI/IIOP, where you use COSNaming as a registry, which doesn't have that registriction, and which also has location-independent object identifiers
(b) Jini.

Creating a single context index on a one-to-many and lookup table

Hello,
I've been successfully setting up text indexes on multiple columns on the same table (using MULTI_COLUMN_DATASTORE preferences), but now I have a situation with a one-to-many data collection table (with a FK to a lookup table), and I need to search columns across both of these tables. Sample code below, more of my chattering after the code block:
CREATE TABLE SUBMISSION
( SUBMISSION_ID             NUMBER(10)          NOT NULL,
SUBMISSION_NAME           VARCHAR2(100)       NOT NULL
CREATE TABLE ADVISOR_TYPE
( ADVISOR_TYPE_ID           NUMBER(10)          NOT NULL,
ADVISOR_TYPE_NAME         VARCHAR2(50)        NOT NULL

INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (5,3,5,'Williard', 'Forsberg', 'AMS');
COMMIT;I want to be able to create a text index to lump these fields together:
SUBMISSION_ADVISORS.FIRST_NAME
SUBMISSION_ADVISORS.LAST_NAME
SUBMISSION_ADVISORS.SUFFIX
ADVISOR_TYPE.ADVISOR_TYPE_NAME
I've looked at DETAIL_DATASTORE and USER_DATASTORE, but the examples in Oracle Docs for DETAIL_DATASTORE leave me a little bit perplexed. It seems like this should be pretty straightforward.
Ideally, I'm trying to avoid creating new columns, and keeping the trigger adjustments to a minimum. But I'm open to any and all suggestions. Thanks for for your time and thoughts.

I would create a procedure that creates a virtual document with tags, which is what the multi_column_datatstore does behind the scenes. Then I would use that procedure in a user_datastore, so the result is the same for multiple tables as what a multi_column_datastore does for one table. I would also use either auto_section_group or some other type of section group, so that you can search using WITHIN as with the multi_column_datastore. Please see the demonstration below.

Lookup() in ui tree from fxml and lookup from java built tree

Hi,
when I try to find a control by its id I use the lookup()-Method. If I load the ui tree from fxml, I have to call something like root.lookup("#theControlId"). If I built the ui tree in java I can use look("theControlId"). Is this right? I am a little bit confused. Probably the id from fxml is used as id but is meant of the CSS id?
What should I do If I have a mixed ui tree. Some parts from fxml, some parts java coded?
Regards
Oliver

Probably the id from fxml is used as id but is meant of the CSS id?I think the rule is:
1. If there is an fxml id and no css id explicitly set, then the fxml loader will set the css id of the element to the fxml id.
2. If there are both an vxml id and a css id explicitly set, then the fxml loader will set the css id of the element to the explicit id.
For instance:
<Label text="Address Book" fx:id="book"/>
@FXML Label book;After book is injected, it will have the the css id book assigned to it automatically and can be looked up up via:
root.lookup("#book");
<Label text="Address Book" fx:id="book" id="the-cat-in-the-hat"/>
@FXML Label book;After book is injected, it will have the the css id the-cat-in-the-hat assigned to it automatically and can be looked up up via:
root.lookup("#the-cat-in-the-hat");As opfl points out, in any case "Search by id must be prefixed with #"

Tab key and lookup table

Hi,
How to use the 'Tab' key to open a lookup table, E.g. BP Code, Name?
Alternatively, how to use the 'Tab' key to call a formatted search? I hope to follow the standard in SBO and do away the Shift-F2.
I am using VB and 2004B. Your input will be appreciated.

I think you can mimic every user action with UIAPI.
Therefore, e.g. in Sales Order Form you activate the BPCode item (.Click) and hit Tab (.SendKeys(vbTab)).
You could also try clicking the the iconitem ("67") next to BPCode.
If you want to assign a Choose From List (CFL) to an item of your choice using UIAPI then you should wait for 2005.
Shift-F2 is standard in SBO UI for launching FSs, why would you like to disable it?
If you want to enable tabbing to kick-off an existing FS, then you should capture the tabbing event (et_KEY_DOWN) in your item and then use SendKeys for sending Shift-F2 to keyboard.

Value Mapping and Lookups

Hi all,
I know something about Value Mapping.
And I heard that the Lookups (DB and RFC) are types of Value Mapping.
I am confused how value mapping is related to lookups.
Request you all to provide me some information regd.this.
Thank you.
Regards
Krishna.

Hi,
All the links above are quite useful in understanding Value Mapping and RFC lookups.
Both solutions could be used for getting values from R3 tables at runtime. However, there's difference in way both operate.
RFC lookup is performed at runtime, since it is executed from the UDF in message mapping. Thus at runtime, call is made to R3 table and value is fetched.
In value mapping replication, Value Mapping program is run from SAP R3 and values from table are updated in XI Runtime Cache. Thus at runtime, while performing message mapping, call to R3 system is not made. Values are available in XI cache.
Thus, it is quite obvious that Value Mapping is more performace efficient since it doesn't make a call to SAP R3 system for each incoming message. If the table data does not change very frequently(since for every change value mapping scenario has to be run for update of XI cache), and it is not very large, then it is a good option as compared to RFC lookup.
However, in cases where either data is frequently changing in table or the volume of data is too large, RFC lookup should be prefered choice.
Hope it would be helpful.
Thanks,
Bhavish

InitialContext and javax.rmi.PortableRemoteObject

I've been trying to locate a very annoying problem that I get when I try to bind remote objects in JNDI. I have now located the problem but I have no idea why this causes a problem or how to fix it. It seems that creating an InitialContext has different effects depending whether I create an instance of javax.rmi.PortableRemoteObject before.
Here's what I am doing...
1:Context ctx = new InitialContext(); //Create Initial context
2://Instantiate remote object (extends PortableRemoteObject and stubs gen with rmic with -iiop flag)
3:Hello hello = new HelloImpl();
4:ctx.rebind("hello", hello); //Bind to JNDI
5:System.out.println("Object bound!!!!!");
This code works fine. The problem occurs when I try to instantiate the remote object before creating the InitialContext for the first time (I.e. I move line 3 to the top) I then get the following exception:
2007-aug-13 09:32:26 com.sun.corba.ee.impl.util.Utility autoConnect
VARNING: "IOP00511403: (INV_OBJREF) Class rmi.HelloImpl not exported, or else is actually a JRMP stub"

at parlayxws.usecases.ejb.px_spec_v2_1.RunEjb.main(RunEjb.java:43)
I assume the problem is in the javax.rmi.PortableRemoteObject's (HelloImpl's) constructor since that is the only code that's beeing executed. But how could that effect the instantiation of the InitialContext? I should also say that it seems that it is only the first time that an InitialContext is created that is critical. If I create on instance of it before instantiating the first PortableRemoteObject, all subsequently created instances of InitialContext succeed in binding remote (RMI-IIOP) objects.
Can someone help me understand why this happens and how to avoid it? I don't want to have to create an InitialContext the first thing I do in the code. It seems the PortableRemoteObject constructor somehow changes the configuration in a way that makes the bindings fail... How? Why? Can I prevent it from happening?
Any input appreciated!

my bean is running in my EJBServer, and I have it in the classpath of the RmiRegistry (which runs as part of my server). The RmiRegistry is an actual ".bat" file that starts an RMI Registry (I assume).
The client is not a bean and is run like this:
java com.titan.cabin.Client_1
All it does is create a cabin and then read it back. It works, it not only gets the context, but also creates, persists and reads that cabin bean.
Is it because java automatically finds all RmiRegistries running on the computer? This makes sense, but I read on java.sun.com that you need a stub class for your clients. And if it is true, then how does it get the context and remote/home interface of a bean on another server?

Data copy and lookup

Hi Gurus,
I have the below scenario and would like to know what would be the best approach.
I have a planning model. (model name = Plan)
I have a copy of my planning model with an additional dimension cost center (model name = plan_copy)
I need to copy data from plan model to plan_copy model and populate the cost center dimension by lookup a DSO in BW.
DSO contains master data with the right keys that I need to lookup while copying data.
Please let me know what would be the best approach to do it?
Should I bring the DSO data in BPC somewhere? I can't bring it in a dimension as its one to many relationship data.
Should I bring it in any type of BPC model and write script logic to lookup in the new BPC model?
Can I use a BADI to lookup in the DSO while copying data?

We performed similar transfer of data from one planning model to another using DM package linked to BADI. In your scenario there is additional complexity of doing lookup from DSO and should be possible.
Also check these references for performing lookup in DSO.
abap code to populate data from DSO
something about SAP: How to look for DSO&#8217;s tables?
