J2ee Connector basic questions

          Hi all,
          I have a few basic questions about j2ee technology and legacy systems.
          In the past year I have used Bea Jolt to "talk" with Tuxedo legacy code,now I
          read about weblogic j2ee Connector and I have the following question: they are
          2 technology in competition, or they can be collaborative ? I mean If I want to
          "talk" to legacy system I can choose between:
          1) "portable" solution (so I keep j2ee Connector)
          2) Vendor tecnology (Bea Jolt or Tuxedo connector)
          Please correct me if I'm wrong...I'm a bit confused on this topic....
          Thanks
          Francesco

Basic questions about Notes domino connector

Hi,
I have a very basic question about the Lotus Domino connector for OIM. We have a requirement to provision accounts into the domino mail server and while doing that also update some information directly into a separate nsf file.
I checked the documentation and it seems while configuring an IT resource, we need to give the Mail DB path, and thats the only place where it refers to it.
Could you guys please let me know if this can be done? Can I write directly to a different nsf file, which is not like provisioning to the complete mail server. So the other attributes in the IT resource may not be able to be set up as its just the file I need to provision into.
Looking forward to your response.
Thanks, M

Does j2ee connector support socket connection?

Can I write a resource adapter to connect with a socket server?


Thanks a lot. I think I will also be a beaer, since I was borlander before.
          This problem cause by I installing wls7.0 and wls6.1 together. After I
          remove wls7.0, everything ok! I think you should check this problem.
          May I introduce our project at first? Now our team is developing Telecom OSS
          system. there is lots of legancy system written by unknown language and in
          unknown tier. The Telecom customer want to put new system into execution
          smoothly. I think about WLI. As you said, I can use adapter in weblogic,
          aren't I? I am not very clear. I will check by myself.
          I have also asked another question in other group, but no answer. it is:
          How to use weblogic.j2eeclient.Main? I really want to have a general test
          ejb client. That is, given ejb classes name and method name and method
          parameter value, I can get any ejb object method result. How can I do it?
          Can reflection and classloader do it?

OC4J 9.0.4 stand alone - basic questions

Hi,
I'm upgrading my web applications from OC4J (1.0.2.2) to OC4J 9.0.4.
I have a few basic questions. Since I asked these as part of another thread and didn't get a response, I thought starting a new thread might help...
1. Does the JSP compiler in OC4J 9.0.4 (JSP container) work with the JDK version set in the path ? (I'm not using OJSP).
2. I read that OC4J 9.0.4 is J2EE 1.3 compliant. With OC4J 1.0.2.2 , I used the j2ee.jar file (that was bundled with J2SDKEE 1.3) to compile my Servlets/Struts code. I copied it into the OC4J_HOME directory and set the Classpath to it, to build my classes.
With 9.0.4, can I still use this j2ee.jar file or do I need to use the jar files (Servlet.jar) in the OC4J_HOME/lib directory?
3. Could somebody throw some light on why some jar files are placed in OC4J_HOME while others are in the OC4J_HOME/lib directory ? What is the difference?
Any help/suggestions will be greatly appreciated.
Thanks,
Shyam

Hi, shyam:
It is nice to raise different questions in different threads.
1. Does the JSP compiler in OC4J 9.0.4 (JSP container) work with the JDK version set
in the path ? (I'm not using OJSP).I believe you are referring to the runtime JSP engine, which compiles your JSP when you first access it. The answer is yes.
To see the compilation setting when oracle jsp engine is compiling jsp files, start oc4j with the debug flag:
java -Dbuild.debug=true -jar oc4j.jar
2. I read that OC4J 9.0.4 is J2EE 1.3 compliant. With OC4J 1.0.2.2 , I used the
j2ee.jar file (that was bundled with J2SDKEE 1.3) to compile my Servlets/Struts code.
I copied it into the OC4J_HOME directory and set the Classpath to it, to build my
classes. With 9.0.4, can I still use this j2ee.jar file or do I need to use the jar files
(Servlet.jar) in the OC4J_HOME/lib directory?Not sure what to say about j2ee.jar of j2SDKEE1.3 since I have never used it. For Servlet code, they are pure java code as long as you use the right libraries. Use the one in OC4J_HOME/lib if possible, although it probably does not matter much. For JSP file, there is no problem of compilation if you do not want to precompile them. All you need is packaging them and deploying them.
3. Could somebody throw some light on why some jar files are placed in OC4J_HOME
while others are in the OC4J_HOME/lib directory ? What is the difference?The executable jars are in OC4J_HOME directory. Besides that, I do not see see much difference.

Mind answering some basic questions for a few bright HS students?

I am a HS computer science teacher who seeks a professional mentor regarding JDBC. While I have successfully
- installed a MySQL database,
created, queried, updated the database,
- read the Java Tutorial and:
used Connect/J and written a main method to manipulate a
database
created very simple applets to query or update a database with
their run methods.
I have basic questions about how pieces fit together in web application development and how one can best take advantage of OOP when dealing with a database. My motivation are a few very bright post-AP students who have an excellent grasp of OOP and data structures; they are curious to see how Java is used in web applications.
The sample code I have found on the Web has all been small main method examples. I would like to see and discuss a truly OOD application with JDBC, and to discuss how the pieces fit together.
So, aware of our ignorance and of how dangerous a little knowledge can be, and not expecting to go live with an application anytime soon, we seek a very high level understanding of current professional practice (like: "Where does tomcat fit in here?") as well as some direction while we get our hands dirty. (I hope that makes sense.)
If you have time to correspond with us via e-mail, answer some very basic questions, and perhaps take a look at some code as we work through it, we would love to hear from you off-line ([email protected]). We would also appreciate knowing where to look for a good OOD sample application. Thanks.

Complete this tutorial and you will have a much better understanding.

Basic question on Adobe document services

Hi
We have a ECC50 instance - the basis component of which has been given to us from our headquarters that has stripped off the J2EE server ( i.e given a WAS640 with just the ABAP runtime installed ).
Now, we are planning to use Adobe Interactive forms - for simple applications - like our field sales able to create a sales order by entering data -offline and submitting it to our ECC50 box.
Now, question is - the ADS - that provides runtime services - does it need a J2EE server - or can I assume that this version of our ECC50 has ADS installed on the ABAP stack - and we still go ahead and plan using Adobe Interactive Services assuming that ADS ( PDF document object )would be available to our ABAP environment to process a PDF form that comes in from field sales ?
Thanks in advance for answering this very basic question.

Hello Karthik,
the ADS only runs on the Java stack, so yes you will need to have SAP Web AS Java installed to deploy and run Interactive Forms.
The functionality of ADS can then be accessed both from Java and ABAP applications.
Cheers,
Matthias

J2EE Connector Architecture(Omni Portlet)

Hello,
In the Developer Guide ,(http://download-west.oracle.com/docs/cd/B14099_10/portal.1012/b14134/pdg_matrix.htm#CEGFBJEC)
it is mentioned about J2EE Connector Architecture as a data source. In the omni portlet data source type it is not listed. How can I configure and use it for data source?
I am using 9.0.4 version of Portal
Any help is highly appreciable.
Thanks

We are trying to do a JCA Adapter and are running into the same type of questions as you. Clearly, no one is watching this topic. Have you found a reference application to test the RA against?

Basic question

Hello, i have a basic question. if i have defined 2 fields in a cube or a dso:
Name Quantity
and from the external flat file i get some characters for my quantity field. would my load fail? for standard dso and for write optimized?
NOTE: quantity field is a keyfigure defined as numeric.
and the load coming in has "VIKPATEL" for Quantity field and not numbers.
thanks

Hi Vik,
Yes, the load will fail.
May be you coud first load this data into BW (into PSA) and set both fields as characters fields. Then you can create DSO, do transformation from this PSA to the DSO, and put your logic as to what do you want to do with those Quantity that is not number (e.g. convert to 0, or 'Not assgined', etc).
You can use transfer rule, or a clean up ABAP code in the start routine.
Hope this helps.

Pl/sql vs sql basic question

Hi,
I have a very very basic question, so excuse me for that... I just would like to know the difference ( and the difference in usage) between sql and pl/sql?
thank you
Yann

SQL - the structured query language - is the language available for extracting data from the database. It is a 4GL, and each command stands alone and performs a database action.
PL/SQL is the 3GL primarily intended to control the flow of a series of SQL commands. PL/SQL does not, in any way, interact with the data in the database. It does, however, allow SQL statements to be called, or even created, in a specific order.
SQL is capable of a LOT more than people usually realize. Unfortunate, as people often create PL/SQL programs when single SQL statements will do the job. I encourage reading the O'Reilly 'Mastering Oracle SQL' book ... only after fiunishing that book do I recommend any of Feuerstein's excellent PL/SQL books.

Basic questions on data modeling

Hi experts,
I have some basic questions regarding data modeling within MDM. I understand the available table types and the concept of lookup fields. I know that the MDM data modeling concept is different to the relational concept. But having a strong database background my first step was to design a relational data model which I would like to transfer to a MDM repository. Unfortunately I didn't found good information material on this. So here are some questions maybe you can help me:
1) Is it the right approach to model n:m relationships with multivalued lookup fields? E.g. main table Users with lookup field from subtable SapAccounts (a user can have accounts in different SAP systems, that means more than one account).
2) Has a record always be unique in MDM repositories (e.g. should we use Auto ID's in every table or do we have to mark a combination of fields as unique)? Is a composite key of 2 or more fields represented with marking these fields as unique?
3) The concept of relationships in MDM is only based on relationships between single records (not valid for all records in a table)? Is it necessary to define all relationships similar to the relational data model in MDM? Is there something similar to referential integrity in MDM?
4) Is it possible to change the main table to a sub table later on if we realize that it has also to be used as a lookup table for another table (when extending the data model) or do we have to create a new repository from scratch?
Thank you for your answers.
Regards, bd

Yes you are correct. It is almost difficult to map relational database to mdm one. But again MDM is not 'just' a database. It holds much more 'master' information as compared to any relational db.
1) Is it the right approach to model n:m relationships with multivalued lookup fields? E.g. main table Users with lookup field from subtable SapAccounts (a user can have accounts in different SAP systems, that means more than one account).
Yes Here you need to use MV look up tables or can also try Qualifier tables if it gets more complex
2) Has a record always be unique in MDM repositories (e.g. should we use Auto ID's in every table or do we have to mark a combination of fields as unique)? Is a composite key of 2 or more fields represented with marking these fields as unique?
Concept of uniqueness differs here that you also have something called Display Fields (DF). A combination of DF can also be treated as Unique one. For instance while importing records if you select these DF as a combination, you will eliminate any possible of duplicates based on this combination. Auto Id is one of the ways to have a unique id once record is within MDM. While you use UF or DF to eliminate any possible duplicates at import level
3) The concept of relationships in MDM is only based on relationships between single records (not valid for all records in a table)? Is it necessary to define all relationships similar to the relational data model in MDM? Is there something similar to referential integrity in MDM?
Hmm... good one. Referencial Integrity. What I assume you are talking is that if you have relationships between tables then removing a record will not be possible as it is a foreign key for some record. Here MDM does not allow that. As Relationships within MDM are physical and not conceptual. For instance material can have components. Now if material does not exist then any relationship to components is not worthwile to maintain. Hence relationshsip is eliminated. While in relational model relationships are more conceptual. Hence with MDM usage of lookups and main table you do not need to maintain these kind of relationships on your own.
4) Is it possible to change the main table to a sub table later on if we realize that it has also to be used as a lookup table for another table (when extending the data model) or do we have to create a new repository from scratch?
No. It is not possible to convert main table. There is only one main table and it cannot be changed.
I went for the same option but it did not work. What I suggest is to look up your legacy system one by one and see what fields in general can be classified as Master, Reference, Transactional - You will start getting answers immediately.

Basic question regarding SSIS 2010 Package where source is Microsoft Excel 97-2005 and there is no Microsoft office or Excel driver installed in Production

Hi all,
I got one basic question regarding SSIS 2010 Package where source is Microsoft Excel 97-2005. I wanted to know How this package works in production where there is no Microsoft office or Excel driver installed. To check that there is excel driver installed
or not, I followed steps: Start-->Administrative Tools--> Data Sources(ODBC)-->Drivers and I found only 2 drivers one is SQL Server and another one is SQL Server Native Client 11.0.
Windows edition is Windows Server 2008 R2 Enterprise, Service Pack-1 and System type is 64-bit Operating System.
We are running this package from SQL Server Agent and using 32-bit (\\Machine_Name\d$\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\DTExec.exe /FILE "\\Machine_Name\d$\ Folder_Name\EtL.dtsx" /CONFIGFILE "\\Machine_Name\d$\Folder_Name\Config.dtsConfig"
/MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING E) to run this package. I opened the package and tried to find out what connection we have used and found that we have used "Excel Connection Manager" and ConnectionString=Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=F:\Fares.xls;Extended Properties="EXCEL 8.0;HDR=YES"; and source is ‘Excel Source’
I discussed with my DBA and He said that SSIS is having inbuilt Excel driver but I am not convinced.
Could anyone please clear my confusion/doubt?
I have gone through various links but my doubt is still not clear.

Thanks Shiven:) If Answer is Helpful, Please Vote

Hi S Kumar Dubey,
In SSIS, the Excel Source and Excel Destination natively use the Microsoft Jet 4.0 OLE DB Provider which is installed by SQL Server. The Microsoft Jet 4.0 OLE DB Provider deals with .xls files created by Excel 97-2003. To deal with .xlsx files created by
Excel 2007, we need the Microsoft ACE OLEDB Provider. SQL Server doesn’t install the Microsoft ACE OLEDB Provider, to get it we can install the
2007 Office System Driver: Data Connectivity Components or
Microsoft Access Database Engine 2010 Redistributable or Microsoft Office suit.
The drivers listed in the ODBC Data Source Administrator are ODBC drivers not OLEDB drivers, therefore, the Excel Source/Destination in SSIS won’t use the ODBC driver for Excel listed in it by default. On a 64-bit Windows platform, there are two versions
of ODBC Data Source Administrator. The 64-bit ODBC Data Source Administrator is C:\Windows\System32\odbcad32.exe, while the 32-bit one is C:\Windows\SysWOW64\odbcad32.exe. The original 32-bit and 64-bit ODBC drivers are installed by the Windows operating system.
By default, there are multiple 32-bit ODBC drivers and fewer 64-bit ODBC drivers installed on a 64-bit platform. To get more ODBC drivers, we can install the 2007 Office System Driver: Data Connectivity Components or Microsoft Access Database Engine 2010 Redistributable.
Besides, please note that 2007 Office System Driver: Data Connectivity Components only install 32-bit ODBC and OLEDB drivers because it only has 32-bit version, but the Microsoft Access Database Engine 2010 Redistributable has both 32- bit version and 64-bit
version.
If you have any questions, please feel free to ask.

If I upgrade to Mountain Lion on the computer that will install it, will my WIFI still work on the computer that cannot be upgraded? I know this is a very basic question

If I upgrade to Mountain Lion on the computer that will install it, will my WIFI still work on the computer that cannot be upgraded? I know this is a very basic question. Trying to hold out as long as I can, but purchasing an iPhone for Christmas and new iMac next year when warrently expires.

Thank U very much for the quick reply, I wanted to upgrade this weekend, but still on the fence. I can live with the software that is not compatible, they are on another compuetr, just didn't want the obvious stuff to stop working.

Basic questions about Infocube

Hi, everyone.
I got very basic questions about infocube data handling.
With infopackage, I extracted all the data about employees from R/3.
But there were some mistakes during inputting employee data, like positions,
so I just extracted those employees data once more.
Now I have two requests in infocube, where the first one has some wrong data.
Is there any solutions about this?
I might got it all wrong, so as beginner, any suggestions and explanations will
be grateful.

Hi,
You can manually delete the earlier request by going in the Manage option of the cube. select the request and click on delete icon at the bottom.
Other option is to make setting in the Infopackage to delete similar or overlapping request.
Data target tab --> 6th column Automatic loading / deletion of similar request. --> click on the blank icon --> you will get a pop-up --> select the radio button - "delete existing request" --> Select Conditions --> Infosource are same, datasource are same and source system are same, --> selections are "Same or More Comprehensive "
Assign points if useful
