Simple Java Oracle Interaction

I am completely new to using Java to access Oracle. I have a very simple project and everything I can find on Java/Oracle interaction seems much more complex than my needs.
Simply put, I need to query my DB (oracle10g) and gather the results into a JTable. That is it. What would be very useful is something like Sun provides with their API Specifications, but for the Oracle commands I would need to implement this. Can anyone point me in the right direction??
Finally, in order to access and oracle DB from Java, must I be developing in J2EE, or will regular old Java do the trick??
Thanks in Advanced

J,
If you downloaded the entire JDK (from SUN), it contains some sample code on how to connect a "JTable" to a database. Look in the "demo\jfc\TableExample" subdirectory (of your JDK installation).
Oracle provides lots of sample code, as well. Have you looked at the JDBC page of the OTN Web site?
No, you don't need to use J2EE.
Good Luck,
Avi.

How to Deploy a Simple Java Web service in Oracle E Business Suite Server

Hi,
I have created a simple Java webservice using Jdev11g.
I am able to Test the Webservice using Jdev11g itself.
How Can i migrate the same to Oracle E Busienss Suite( - 9iAS ) so that webservice clients connect to 9iAS instead of my local machine
Thanks,
Gowtam.

Hi Sudhakar,
If you are used to working with ant then you can very well use eclipse to deploy your web service.
You would usually have the ant script in the source root working directory. From eclipse if you select the build file from the navigator view and right click you will see a run ant option in the pop up menu.
Select that option and you would be able to see each targets with a checkbox select option. So define each target maybe one for wsdl2java conversion, one for compilation and one for deploying your web services. You can either make all of them run by having depends option on or you can run them individually as it takes your fancy.
I am not sure about debugging a web service yet.
Hope this helps

The truth is out there? Does anyone know the URL?

PL/SQL Object Type - Java oracle.jbo.domain

PL/SQL Object Type <-> Java oracle.jbo.domain
can anybody help me, getting my domains to work?
Following scenario:
in pl/sql we have an object type called MULTI_LANGUAGE. This type is used for storing multilingual texts as nested table in one(!) column.
So the object MULTI_LANGUAGE contains a member variable LANGUAGE_COLLECTION of type LANGUAGE_TABLE, which itself is a nested table of objects
of the type LANGUAGE_FIELD (this again is only a language id and the corresponding content)
Also the methods setContent(langID, langContent) and getContent(langId) are defined on Object MULTI_LANGUAGE.
For example: Table having primary key, 2 other columns and one column of object type MULTI_LANGAGE (=nested table of objects)
|ID|Column1|Column2| multilingual Column |
|--|---------------------------------------|
| |       |       | ------------------- |
| |       |       | | 1 | hello         | |
| |       |       | ------------------- |
|1 | foo   | bar   | | 2 | hallo         | |   <- Row Nr 1
| |       |       | ------------------- |
| |       |       | | 3 | ola           | |
| |       |       | ------------------- |
|--|-------|-------|-----------------------|
| |       |       | ------------------- |
| |       |       | | 1 | world         | |
| |       |       | ------------------- |
|2 | abc   | def   | | 2 | welt          | |   <- Row Nr 2
| |       |       | ------------------- |
| |       |       | | 3 | ??? ;-)      | |
| |       |       | ------------------- |
|--|-------|-------|-----------------------|Now i've tried to modell this structure as an oracle.jbo.domain.
class MultiLanguage extends Struct having this StructureDef:
attrs[(0)] = new DomainAttributeDef("LanguageColl", "LANGUAGE_COLL", 0, oracle.jbo.domain.Array.class, 2003, "ARRAY", -127, 0, false, "campusonlinepkg.common.LanguageField");
and
class LanguageField extends Struct having this StructureDef:
attrs[(0)] = new DomainAttributeDef("Id", "ID", 0, oracle.jbo.domain.Number.class, 2, "NUMERIC", -127, 0, false);
attrs[(1)] = new DomainAttributeDef("Content", "CONTENT", 1, java.lang.String.class, 12, "VARCHAR", -127, 4000, false);
Is there anything wrong with this StructureDef?
When running the BC-Browser with -Djbo.debugoutput=console -Djbo.jdbc.driver.verbose=true parameters I get suspect warnings when browsing the records

Seems as if the framework can't read the TypeDescriptor or does not know which descriptor to read (XMLTEST.null??)
Do I have to implement my own JboTypeMap?
Please help, I'm stuck.
Thanks in advance, Christian

Thanks for your suggestion, but it seems to me as if there is one level missing.
in pl/sql I have following structure:
Struct MULTI_LANGUAGE (Object type) - outermost
Array LANGUAGE_TABLE (nested table type)
    Struct LANGUAGE_FIELD (Object type simple) - innermostthe reason why i had to wrap another struct around the array was because it is not possible to define methods on a nested table. this is only possible on objects.
on the outermost object type (which holds the array of language fields) I needed to define following 2 methods for direct access:
getContent (langId in number) returns varchar2
setContent (langId in number, langContent in varchar2)
I would like to rebuild the same structure in java, because newly written java code should live in perfect harmony with legacy pl/sql code ;-)
Both applications (Java and pl/sql) have to access the same data as long as migration to java goes on.
Is this nested structure too much for a Domain?
Any other suggestions?
Thanks again, Christian

Calling simple Java Code from 11g BPM

Hi,
I know this has been round the houses but I cant find a satisfactory solution for my scenario. I would like to call some simple java code from BPM (11.1.1.6). I guess I need to expose it as a service but it seems overkill to be via soap so any advice you can give would be much appreciated. Creating a jar that I can call somehow would be perfect.
This is my scenario:
- I am creating a Security POC for BPM
- The BPM Process is exposed as a web service and authenticated using SAML
- I am testing by calling the WS from OSB
- I want to be able to get the WLS Principal and display the username and the roles for the launching user, from within the BPM process
- This is possible using some simple weblogic client api code shown below
- So all I want to do is call this code from BPM somehow
- Anyone point me in the right direction ?
cheers
Tony
subject = Security.getCurrentSubject();
for(Principal p: subject.getPrincipals()) {
if(p instanceof WLSGroupImpl) {
groupList.add(p.getName());
} else if (p instanceof WLSUser) {
principal = p.getName();
}

The problem to communiate java classes and forms solved !
i have add my .jar file to $OA_JAVA/oracle/apps/fnd/jar and now i can communicate between forms and java.
I can create an object, i can get simple message from class, but when i try to create
ServiceFactory factory = ServiceFactory.newInstance();
ive got ORA-105100...
can anybody help ?

Missing Defines Error in Simple Java Stored Procedure

Anyone have any suggestions on what might be causing the unusual behavior described below? Could it be a 10g java configuration issue? I am really stuck so I'm open to just about anything. Thanks in advance.
I am writing a java stored procedure and am getting some SQLException's when executing some basic JDBC code from within the database. I reproduced the problem by writing a very simple java stored procedure which I have included below. The code executes just fine when executed outside of the database (10g). Here is the output from that execution:
java.class.path=C:\Program Files\jEdit42\jedit.jar

Executing outside of the DB
Driver Name = Oracle JDBC driver
Driver Version = 10.1.0.2.0

Simple Java class using SQLJ not compiling.

Hello all, I have a simple Java class that is using SQLJ. It will not compile though. I am not sure what I should set for classpath. Any ideas? This is what I have so far.
set PATH=C:\jdk1.2.2\bin;c:\oracle\ora81\jdbc\bin;

then
javac SQLJTester.java
Here is my .java file ---
import java.io.*;
import java.sql.*;
import sqlj.runtime.*;
import sqlj.runtime.ref.*;
public class SQLJTester {
public static void update() throws Exception {
java.sql.Timestamp timeNow;

END
public static void main (String[] args) {
try {
SQLJTester.update();
System.out.println ("Updated successfully");
catch (Exception e) {
System.out.println ("Caught an exception.");
Thanks ahead for your time,
Justin

When sqlj files are compiled and translted to java file with them the file with extension .ser is also generated. browsers do not recognise this .ser files they only understand .class files which the download using <codebase> instead of class path. so thats why you r not able to use sqlj in servlet. try to customize the profile. Now can some one inform how to use sqlj from eclipse. does it support?. i need to downoad sqlj.exe for that. if anyone has idea from where i can download sqlj.exe pls inform me at [email protected]

Simple Java DB example

I am using Java 1.6 and Eclipse Galelio on Vista, Do I need to configure anything is there any story of setting path?
How to check my Java DB is working or not or everything is fine or not?
I found many totorial with simple Java DB example but they seem dealing with previous version of JDK, I guess SUN too on http://java.sun.com/developer/technicalArticles/J2SE/Desktop/javadb/ , kindly provide me the simplest example which uses Java DB.
I am not able to figure out the whole thing of JAVA DB , how it works, in plain language I want to know is there any way of interacting with database from Command prompt? If so how?

A simple Java program to be compiled with ojc and executed with java.exe

Hi ,
This thread is relevant to Oracle Java Compiler (file ojc) and jave.exe file.
I have written a simple java program which consists of two simple simple classes and using the JDev's 10.1.3.2 ojc and java files , i'm trying to execute it after the successful compilation....
The problem is that trying to run it... the error :
Exception in thread "main" java.lang.NoClassDefFoundError: EmployeeTest

How can i solve this problem...????
The program is as follows:

For compilation... i use :

For execution , i issue the command:
D:\ORACLE_UNZIPPED\JDeveloper_10.1.3.2\jdk\bin\java EmployeeTest
NOTE:I tried to use the jdk of Oracle database v.2 but the error :
Unable to initialize JVM appeared....
Thanks , a lot

Hi,
Thanks god....
I found a solution without using Jdev.....
C:\oracle_files\Java\Examples>SET CLASSPATH=.;D:\E-Book\Java\Sun_Java_Book_I\Corejava
C:\oracle_files\Java\Examples>D:\ORACLE_UNZIPPED\JDeveloper_10.1.3.2\jdk\bin\javac EmployeeTest.java
C:\oracle_files\Java\Examples>D:\ORACLE_UNZIPPED\JDeveloper_10.1.3.2\jdk\bin\java EmployeeTest
What does Ant has to do with this?Sorry, under the Ant tree a classpath label is found....I'm very new to Java and JDev...
You need to include the jar file that has the Day method in it inside project properties->libraries.I have not .jar file.. just some .java files under the corejava directory.... By the way , I have inserted the corejava directory to the project pressing the button Add Jar/Directory.... , but the problem insists..
Thanks , a lot

How to pass a HTTP request from a simple java class

Is it possible to pass an HTTP request from a simple java class.if yes how?

Is it possible to pass an HTTP request from a simple
java class.if yes how?If you're talking about creating a HttpRequest object and passing it to a servlet, that would be a red flag to me that your design is flawed. You shouldn't have to do that - the application server (Tomcat, Weblogic, etc) should be the only thing that has to worry about creating that kind of object and passing it to you.

How do I call a simple java class from a bpel process?

Hi.
In JDeveloper 10.1.4.3.0 I've created a simple java class that does an ftp get operation followed by an unzip. The class uses some 3rd part libraries (jars).
I want to use a simple bpel process to schedule a daily execution of this java class, and deploy it all to our SOA-server, - and was looking into using the <bpelx:exec> function.
The java class and the bpel process is all stored in the same JDeveloper project.
How do I put this together so that both my java class and the necessary jars are available to the bpel process?
I've looked into the JavaExecSample.bpel, and it's says something about "...the class com.otn.samples.javaexec.CreditCalculator is locally packaged with this BPEL process".
How do I do that?
Can I make it and test it all locally from my workstation (only JDeveloper installed, I guess there's nothing that can execute the bpel code?), or do I have to compile class etc (make war-file?) and deploy to SOA server (BPEL-INF/lib or classes?) before anything can be tested?
(I guess all this is simple, once you know how, but being a newbie to this I need a shove in the right direction :-)
Regards,

To create a java class and dependent jars inside the BPEL process project you need to do the following:
1. Right click on your BPEL process project and select New and then Java Class from the Items.
2. Make the BPEL process project, JDeveloper would compile the java classes and add them into the BPEL suite case jar, see the output folder and check the BPEL suite case jar file for java classes and dependent jars.
You can test your Java classes from JDeveloper IDE, no need to deploy the classes on SOA server. When you make the BPEL project it compiles .bpel files and Java classes. You can test your classes once .bpel file and java classes compiled successfully.

Efficiency Question: Simple Java DC vs Used WD Component

Hello guys,
The scenario is - I want to call a function that returns a FileInputStream object so I can process it on my WD view. I can think of two approaches - one is to simply write a simple Java DC that does so and just use it as a used DC so I can call the functionality from there. Or create another WD DC that exposes the value (as binary) via component interface.
I'm leaning on the simple Java DC approach - its easier to create. But I'm just curious on what would be the Pro-side (if there's any) if I use the WD Component interface approach? Is there a plus for the efficiency? (Though I doubt) Or is it just a 'best/recommended practice' approach?
Thanks!
Regards,
Jan

Hi Jan
>one is to simply write a simple Java DC that does so and just use it as a used DC so I can call the functionality from there
Implemented Java API for the purpose mentioned in your question is the right way, I think. The Java API can be even located in the same WebDynpro DC as your WebDynpro components. There is not strongly necessity to put it into separate Java DC.
>Or create another WD DC that exposes the value (as binary) via component interface
You should not do this because in general WD components' purpose is UI, not API. Implementing WD component without any UI, but with some component interface has very-very restricted use cases. Such WD component shall only be a choice in the cases when the API is WebDynpro based and if you have to strongly use WebDynpro Runtime API in order to implement your own API.
If your API does not require WebDynpro Runtime API invocations or anything else related to WebDynpro then your choice is simple Java API.
>But I'm just curious on what would be the Pro-side (if there's any) if I use the WD Component interface approach? Is there a plus for the efficiency?
No. Performance will be better in simple Java API then in WebDynpro component interface. The reason is the API will not pass thought heavy WebDynpro engine.

What's wrong with this simple java file

I am learning java input methods. When I tried to compile the below simple java file, there were two errors.
import java.io.*;
public class MainClass {
   public static void main(String[] args) {
    Console console = System.console();
    String user = console.readLine("user: ");
    System.out.println(user);
}The compiler errors:
h:\java\MainClass.java:5: cannot resolve symbol
symbol : class Console
location: class MainClass
Console console = System.console();
^
h:\java\MainClass.java:5: cannot resolve symbol
symbol : method console ()
location: class java.lang.System
Console console = System.console();
^
2 errors
Could anyone take a look and shed some lights on this?

I have changed to "import java.io.Console;" but this below errors:
h:\java\MainClass.java:1: cannot resolve symbol
symbol : class Console
location: package io
import java.io.Console;
^
h:\java\MainClass.java:5: cannot resolve symbol
symbol : class Console
location: class MainClass
Console console = System.console();
^
h:\java\MainClass.java:5: cannot resolve symbol
symbol : method console ()
location: class java.lang.System
Console console = System.console();
^
3 errors

How to get the profile object in simple java class (Property accessor)

Hi All,
Please guide me how to get the profile object in simple java class (Property accessor) which is extending the RepositoryPropertyDescriptor.
I have one requirement where i need the profile object i.e i have store id which is tied to profile .so i need the profile object in the property accessor of the SKU item descriptor property, which is extending RepositoryPropertyDescriptor.
a.I dont have request object also to do request.resolvename.
b.It is not a component to create setter and getter.It is simple java class which is extending the RepositoryPropertyDescriptor.
Advance Thanks.

Iam afraid you might run into synchronization issues with it. You are trying to get/set value of property of a sku repository item that is shared across various profiles.
Say one profile A called setPropertyValue("propertyName", value).Now another profile B accesses
getPropertyValue() {
super.getPropertyValue() // Chance of getting value set by Profile A.
// Perform logic
There is a chance that profile B getting the value set by Profile A and hence inconsistency.
How about doing this way??
Create PropertyDescriptor in Profile (i.e user item descriptor), pass the attribute CustomCatalogTools in userProfile.xml to that property.
<attribute name="catalogTools" value="atg.commerce.catalog.CustomCatalogTools"/>
getPropertyValue()
//You have Profile item descriptor and also storeId property value.
// Use CustomCatalogTools.findSku();
// Use storeId, profile repository item, sku repository item to perform the logic
Here user itemdescriptor getPropertyValue/setPropertyValue is always called by same profile and there is consistency.
