Performance of mapping Oracle objects to Java classes

Hi,
By retrieving some test data from Oracle database in a Java application, I compared the traditional JDBC/RDBMS solution to JPublisher-generated-classes/Oracle-object-tables solution. The underlaying Oracle database and the client environment was the same in both tests. Although the table schemas were different, they represented the same data.
It seems that the traditional JDBC/RDBMS solution is much faster. Is this a reality or did I make a mistake somewhere?
BR,
Timo

I am also facing performance overhead when using Jpub generated
classes for the object types.
I am using 817 jdbc and jpub but my database is 816. I have seen
that following statements each take around 2-3 seconds to
execute. Is there any communication between driver and database
to resolve the object type ?
Please help.
cCallableStatement =
(OracleCallableStatement)m_cConnection.prepareCall("{call
list_unsync_appts_array(?,?,?,?,?,?,?,?)}");
((OracleCallableStatement)cCallableStatement).setCustomDatum(1,ct_number_arr);
cCallableStatement.registerOutParameter(2,OracleTypes.ARRAY,"T_EVENT_SUMMARY_ARR");
cCallableStatement.registerOutParameter(3,OracleTypes.ARRAY,"T_EVENT_DETAIL_ARR");
cCallableStatement.registerOutParameter(4,OracleTypes.ARRAY,"T_EVENT_SUMMARY_ARR");
cCallableStatement.registerOutParameter(5,OracleTypes.ARRAY,"T_EVENT_DETAIL_ARR");
cCallableStatement.registerOutParameter(6,OracleTypes.ARRAY,"T_EVENT_SUMMARY_ARR");
cCallableStatement.registerOutParameter(7,OracleTypes.ARRAY,"T_ATTENDEE_EMAIL_ARR");
cCallableStatement.registerOutParameter(8,OracleTypes.ARRAY,"T_ATTENDEE_EMAIL_ARR");
cCallableStatement.execute();

Mapping Value Objects to Java Classes

Hi All,
I have one Java Class:
public class MyBean {
    private ArrayList numbers;
I have created one mapping value object for the same in Flex:
package vo
    import mx.collections.ArrayCollection;
    [RemoteClass(alias="com.tcs.example.MyBean")]
    public class MyBean
        public function MyBean()
        public var numbers:ArrayCollection;
but when I fetch the object using Remote Object, the returned object has "numbers" as null even though I'm returning from Java a filled ArrayList.
Does any one know Why is it happening and what should I do for this.
Thanks in advance

Do you have getNumbers and setNumbers methods on your java bean?
Try to activate the logs on blazeDS to see what's going on.

How to use Oracle objects in java code

Hi all!
I'm reading an xls and i need to fill me oracle objects with java code:
OBJECT_NAME OBJECT_TYPE
LETTURA_OBJ TYPE
LETTURA_OBJ TYPE BODY
In the past weeks i've been using both java code into oracle and oracle objects, but new i need to write those objects with data i read with java, anybody can help me?
I know that the easiest work around would be to put the data i read from the excel file into a table and then fill the oracle objects, but now i want to learn how to write directly those objects with a command like the following one:
a sample of the code i'm tryng to write:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED REPORT."Manage_Excel_ASMBS" AS
import java.io.*;
import java.io.IOException;
import jxl.*;
public cass ....
#sql{ variabili_globali.var_ER_F3.Tipo_Lettura := 5}
thanks,
Massimo

mmmh i'm not understanding so much....
well... as i told before i'm working in oracle database environment and i'm developing a java procedure.
now, i have this object
CREATE OR REPLACE
TYPE REPORT.FATTURA_OBJ AS OBJECT (
POD VARCHAR2(1000),
ID_FATTURA NUMBER,
ID_FILE NUMBER,
COERENZA_EA_F VARCHAR2(1000),

import java.io.StringWriter;
public class Manage_Excel_ASMBS
public static void read_Excel(String inputFile,int var_Id_Caricamento, int var_Id_Distributore, String var_Distributore) throws SQLException, IOException
**here i need to put what i'm reading inside the excel file into oracle objects**
/can you please give me a sample ?

Equivalent of a prepared stmt (with mapping table to a java class) ?

Hi,
We can fire raw-sql using SQLCall(). Do we have something similar to make and use prep stmts ?
If we have mapped tables to some java classes, this cud be done with the use of toplink 'Query' classes.
But if I dont have anything mapped and want to use the raw-sql kinda method, is it possible to make and use a prep stmt in toplink ?
Thanks,
Krishna

Hi Donald, You are right...I was actually looking for something to use JDBC code directly for these parts. So is there a way to get a java.sql.Connection out of the TopLink session and then fire prepared statements (JDBC code) using that connection ?
Can we do something like this... (do let me know if this is not the right way to do it at all...or if it is not possible at all)
ConnectionPool oCP = RuntimeServices.getConnectionPools().elementAt(0); // plz ignore that i assumed pools are returned as Vector
java.sql.Connection oCon = oCP.getDatabaseLogin().connect(prop); // is it necessary to give prop (since I got it from existing conn pools that are already setup in the server session)
Thanks,
Krishna

HELP IN Creating customized Oracle Object from Java

How can I create a customized oracle object that has these 3 fields with data persistance:
NAME : VARCHAR2
INSER_DATE : DATE
OBJ:user-defined collection(oracle.sql.array)
using JAVA. Later, that oracle object is enqueue in Oracle avanced Queue.
I've been looking in this site for the answer but had no luck.
I am using Java 1.2 and Oracle 8.1.6.
Any help will be appreciated as I needed so badly. Thanks.

Hi
I assume your attempting to generate a Java class with the approriate getters and setters. If so the JPulisher utility is what your after. You can access it from either JDeveloper or the command line... Its documented in the Oracle Java manuals (jdbc etc.)...
A piece of advice... especially if you using AQ and ADT's or oracle's jms implementation against AQ, make sure you use the Oracle 8.1.7 jdbc drivers, even if your accessing an 8.1.6 DBMS. The performance difference is significant

Mapping data model to java classes and Interface.

Need help in mappning my data model into java classes;
Here are some of the details:
Table, Poll:
PollID int
PollName varchar
BusinessUnit varchar
DisplaySchemeID int // reference to DisplayScheme table.
Table, DisplayScheme
DisplaySchemeID
DisplaySchemeName
etc
Table, URL
UrlID
UrlName
UrlDesc
Table, PollURL
PollURLID
PollID
UrlID
PublishDate
etc
Table, Tag
TagID
TagName
PollID
So, a POLL is associate with a DisplayScheme.
A Poll can have many URLs and a URL can be associate with many Polls , mapped in the PollURL table.
and same is the situation with tags.
Essentially I want to learn how to do one to many mappning and many to many mapping.
Also to add, since I plan to use Ibatis for OR mapping.
So I should a Parameter call to map for creaint a Poll. And to create a poll the form submitted will have:
- PollName
- URLs ( multiple )
- one display scheme.
- Tags ( many )
So if you can show how to write a DAO createPoll method, then it would be great.
Not sure if am asking a lot, but this would be a great example to move forward.

The below is the sample DAO Class.
For your case, you have to create your own PollBean with getters and setters and just pass the object to the method
public int create(Connection con, ProjectBean projectBean) throws SQLException {
          int result = 0;
          String insertQuery = " INSERT INTO" +
                    " M_PROJECT(" +
                    " PROJECT_ID," +
                    " PROJECT_NAME," +
                    " PROJECT_DESCRIPTION) " +
                    " VALUES(?,?,?,?)";
          initPrepareStmt(con, insertQuery);
          setString(projectBean.getProjectID());
          setString(projectBean.getProjectName());
          if(projectBean.getProjectDescription().equals("")){
               setString(" ");
          }else{
               setString(projectBean.getProjectDescription());
          result = executeUpdate();
     return result;
     }

Container Object in Java Class

Hello ,
I have a Mapping program using java class type (Java SAX in this case). I need to access some Runtime constants and the mapping trace object.
In message mapping is simple. We can use the container object that is pass to a UDF and the GlobalContainer Object.
But how can I access the Runtime constants and mapping trace without a container object ?.
Any ideas...?
Thanks in advance.
Yuvan D.

in Your java mapping class
you should import import com.sap.aii.mapping.api.*;
public void execute(InputStream input, OutputStream output)
        throws StreamTransformationException {
        AbstractTrace trace = null;
        String RESULT = new String();
        trace =
            (AbstractTrace) param.get(
                StreamTransformationConstants.MAPPING_TRACE);
trace.addInfo(doc.toString());

Working with Oracle Objects in JAVA - How-to do with views

Hello,
I am trying to access to Oracle object types from Java.
My problem is, I have relational tables, Object Types and Object Views.
All the examples I found from Oracle manuals are working with Object Tables(Table column is created as Object Type).
You run a query and get this object type (oraconn.GetObject(1)) and the query is (SELECT * FROM Object_Table) so its get first column(which is an object type) and cast it to Java Class(with SQLDATA or ORADATA).
The problem is that my data is in Relational Tables and I don't want to export them to Object tables.
I want to get it from Object View.
Is this possible? Or better is anybody has an example???
Thx in advance

Hi,
I think you will be able to help me. your question made me to think that you will be able to help me. Here the question goes.
I have a Stored Procedure which returns a user defined ROWTYPE(its a IN OUT param to the procedure). I need to call this procedure from my Java program. So I would like to know how to do it. Do we need to use any packages provided by oracle or some thing like that.

Should I start with Entity Object or Java Class Diagram ??

Hi,
I come to J2EE / OO application development from non-oo programming world. I am still confused about what step-by-step development approach should I take ?
Should I :
- start with creating Entity Object from available database table ?
- should I start with Java class diagram, followed by generating database tables, then create EO from it ?
Could anybody please help me, what best practice step by step development approach should I take ?
Is there any white paper / docs about this ?
Thank you for your help,
Krist

Krist,
If you are not from the OO world then you may be interested in this new site on OTN (http://otn.oracle.com/formsdesignerj2ee) There is a workshop that starts by looking at an existing datamodel and builds up from there.
If you are starting from nothing, you can indeed start higher at the Class Model level.
I recently started discussing data modeling on my blog (http://www.groundside.com/blog/content/SueHarper/) and there are some very good comments(feedback from readers) that may possibly be useful to you.
If you are new to the UML modeling world, I recommend you read two very good papers by Jan Kettenis on OTN (http://www.oracle.com/technology/products/jdev/collateral/collateral10g.html) They are Getting Strted with UML Class modeling and Getting Started with UML Use Case Modeling.
Shay pointed you to Toplink. There are a lot of resources on OTN for Toplink, including tutorials.
Personally? I think if you have time, and if you can, start with a Class Model and perhaps a Use Case model, then you can start planning your application development from a solid base.

Bing Maps REST route service - java classes

I am able to use the WSDL to generate the classes required to hit the SOAP Web Service. But it appears that the classes generated using the SOAP service do not match the classes used for the REST service. How
can I generate the Java classes required for hitting the REST Route Web Service. I am able to call the REST service and get an XML or JSON response, but having issues creating the objects with the data returned.

The REST and SOAP services are completely different. The SOAP services were created about 8 years ago and the REST services about 4 years ago. The REST services have a bunch more features and functionalities. There are a couple of ways you can consume the
Bing Maps REST services in Java. The first is to manually parse the responses. Here are some examples:
http://javaprogramming.language-tutorial.com/2012/10/geocoding-using-bing-rest-api.html
http://javaprogramming.language-tutorial.com/2012/10/reverse-geocoding-using-bing-rest-api.html
https://ngjon.wordpress.com/2011/05/20/bing-maps-geocoding-rest-service-java-ized/
Alternatively you can create a set of classes that can be used for serializing the responses. I have a set of .NET data contracts for the RST services that can be ported to Java here:
http://msdn.microsoft.com/en-us/library/jj870778.aspx
I also created some tools to parse the REST responses in an Android app a while back. You can find the code for that here:

I just skimmed through your email. You said you

the latest SP. There are many bug fixes done
after SP1.
Web service support in 6.1 is very limited. But, It
looks like 6.1 can handle the case you are trying out.

3 Levels Master Detail View Object with Java class interface

Hi Developers,
I've created 3 tables with one to many relations as below
BOARD ------<- APPLICANT ------<- QUALIFICATION
a board includes many applicants and an applicant includes many qualifications.
When I add these tables to a Fusion Project, JDeveloper 11g helps me to add the Entity Links and View Associations automatically.
Then, I defined these relations in an ApplicantModule's Data Model as below.
[+] BoardVO1
      |
      |--[+] ApplicantVO1
               |
               |--[+] QualificationVO1The problem is: I cannot write any function in QualificationVO and publish it by client interface.
I created a simple function with a single line (System.out.println(...) ) in QualificationVOImpl.java. and selected it in Client Interface. But when I execute it from the ApplicantionModel for testing, an oracle.jbo.NoObjException JBO-25003 is raised. with message: Object ... ApplicantVO1 of type ApplicationModule not found.
Has anyone tried to implement some coding in the third level of a master details view structure as my example? How do you make it works?
I'm using JDeveloper 11.1.1.3 with ADF BC.
Regards,
Samson Fu

Samson,
Looks like a bug (probably with the application module tester). I created your tables:
create table board(board_id number primary key not null);
create table applicant(applicant_id number primary key not null, board_id number not null);
create table qualification(qualification_id number primary key not null, aplicant_id number not null);
alter table applicant add a_fk foreign key(board_id) references board;
alter table qualification add q_fk foreign key(aplicant_id) references applicant;I created a JDev project and got the same results. I've e-mailed a test case off to Frank.
Frank - the method is indeed exposed on the VO instance, and I tried testing that way, but the AM tester gives the error as if it is looking for an AM instance with the VO's name.

Java to Oracle Object mapping

Can any one tell me how to map ORacle object to java. I know we can use STRUCT class. I have vector type (which contains array values) and I want to send this data as object to procedure. Thanks !!

Hi Vyshu,
Getting a similar error
"java.sql.SQLException: Non supported character set: oracle-character-set-838".
I'm using Oracle v10g. And i'm getting this exception when accessing one of the TYPE Objects.
I've tried setting the classpath to ojdbc14.jar and orai18n.jar. But, the issue doesn't seem to get resolved.
Have any thoughts in this?????
Tips are welcome from all .... !!!!
