JAVA JDBC code for Oracle 9i

I need java jdbc code for oracle 9i as soon as possible.

All the information you need is on the web. For some of it, you'll need to register with Oracle. It's free and they don't send annoying emails (at least to me).
Sample code:

You don't need a DSN if you use Oracle's JDBC driver.
You didn't read ANY of the previous replies. What makes you think this one willk help? Or any instruction, for that matter?
Sounds like you just want someone to give it to you. OK, I'll bite, but you have to figure out the rest:

Error when SDM JDBC driver for Oracle

When deploying the JDBC driver for Oracle on PI 7.0, I failed to achive. I got the following trace information from SDM.
After checking the system directory structure, I found that very interesting thing. First I downloaded aii_af_jmsproviderlib.sda from the directory of ../SAP AG/0/3.0...and zip oracle jdbc driver into it, and I deployed the sda file with SDM back to the system with the option update deployed SDAs that hava any version. Curious the sda file was put into another directory of ../SAP AG/1/3.0... a new directory which was just created during the deployment.
This never happen before and is this the reason why deploy failed.

How can I install JDBC drivers for Oracle?!?....

i have a program that has this line:
import oracle.jdbc.pool.OracleDataSource;
that gives this error when I compile it:
package oracle.jdbc.pool does not exist
So I think I need to install JDBC drivers for Oracle. (?)
I went here: [http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_111060.html]
and downloaded the files for JDBC Thin.
Then I followed this: [http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/111070_readme.html]
by entering these commands (I'm using Ubuntu):
export CLASSPATH=$CLASSPATH:/path/to/files/ojdbc6.jar
export CLASSPATH=$CLASSPATH:/path/to/files/orai18n.jar
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/files
When I type echo $CLASSPATH I can see that those commands worked, but it hasn't made any difference when I try to compile.
I still get the same error. Is it because I didn't do anything about the .so files? The readme page didn't mention them in the installation section.
Please help! I am so stuck...

I don't think you need the shared libraries (.so files) and given what I saw when I glanced at those pages, I don't think they'd even work for you, although maybe I just didn't read enough of it.
What happens when you type
javap oracle.jdbc.pool.OracleDataSourceon the command line?
How are you invoking javac? Are you perhaps passing a classpath argument?
Are you sure that the path to the jar files is correct? Are the paths relative?

Oracle Fusion Middleware Java API Reference for Oracle ADF Mobile

Where can I find "Oracle Fusion Middleware Java API Reference for Oracle ADF Mobile"?
Thanks a lot for your time.

Hi, this is referring to the JavaDocs for Java methods/classes supported by ADF Mobile. You can typically right (or ctrl) click on any ADF Mobile specific Java method and select "JavaDoc". You can open up a sample app that contains any Java class - for example the HR sample app, and find any method with name "adfmf*". You should be able to see the Java doc for the ADF Mobile related methods/classes.
Thanks,

Can anybody give me the jdbc code for postgres database.

Hello all,
I tried to search for sample jdbc code for postgres. But I couldn't find working sample. Can anybody please post the sample jdbc code for connecting to postgres database.
I have already added the jar file, "postgresql-8.0-312.jdbc3.jar" to the build path.
Thanks.

Hi,
Thanks for your reply!
I wrote the following code, but the insert doesn't add a row.
try {
          Class.forName("org.postgresql.Driver");
          //Preparing Conenction String
          Connection con = DriverManager.getConnection("jdbc:postgresql://<name>:5432/sales_office_test", "sales_office_data","sales_office_data");
          PreparedStatement prepSt = con.prepareStatement(
                              "INSERT INTO office_personnel (office_id, salutation, firstname, lastname, email_address,"
                              + " cellphone, phonenumber, extension, password, username) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");
                         prepSt.setString(1, newOfficeIds);
                         prepSt.setString(2, whopperUserSalutation);
                         //Close statement
                         prepSt.close();
     } catch (ClassNotFoundException e1) {
          // TODO Auto-generated catch block
          e1.printStackTrace();
     } catch (SQLException e1) {
          // TODO Auto-generated catch block
          e1.printStackTrace();
     }If I print the connection object I get
Sql connection value: org.postgresql.jdbc3.Jdbc3Connection@10965c3 I double checked the same query by directly executing it on the web interface to the postgres, works fine there and creates the row...
What could be wrong.
Thanks

Where is java source code for TitledBorder

Where is java source code for TitledBorder?
I don't want to decompile it, as it may be slightly different than the original.
Is it in some jar file on my computer?
Thanks

It's different from the original because the names of objects are different. I decompiled them, because I didn't feel like paging through that URL to find them.
I was trying to fix the TitledBorder, because it leaves like 2 pixels of padding outside of the border, but all the variables I change in that class don't seem to correct that.

Choosing jdbc driver for Oracle 9.0.1 with sdk 1.4.1?

Hi all experts...
I am really beating my head over this... I had java sdk 1.3.1 installed and i am writing an application for oracle database 9.0.1 The driver i had was a classes12.zip file that i included in the classpath to run the application.
Now, i have upgraded my java to 1.4.1 but my application is not picking up the zip file anymore! I am getting No suitable driver:08001 error and NoClassDefFoundError. I checked the oracle website, they dont have a 9.0.1 driver for sdk 1.4.
Is my current driver compatible?
Do i have to upgrade my oracle DB to 9.2 and use another driver?
Or is just one of those classpath problems?
Part of my code is given below:
private static Statement createStatement(String driver, String url, String user, String password)throws IllegalArgumentException, SQLException, ClassNotFoundException
if (url == null || driver == null)
     throw new IllegalArgumentException("No database specified");
try
Class.forName(driver);
catch(ClassNotFoundException e)
System.out.println("Class not found: "+driver);
conn = DriverManager.getConnection(url, user, password);
return conn.createStatement();
CLASSPATH=C:\projects\MauiWSxml\resources\classes12.zip;
I will be grateful to any help ...Pleeeeessseeee
Thanks in advance

Great progress! Excellent!
I'd recommend that you get rid of that CLASSPATH system variable immediately. Don't use it anymore.

}Put this code in a directory with your classes12.zip. Type:
javac -d . -classpath classes12.zip DataConnection.javaYou should get a DataConnection.class file in that directory. Then type:
java -classpath classes12.zip DataConnection <sql> oracle.jdbc.driver.OracleDriver jdbc:oracle:thin:@<host>:1521:<database> <username> <password>where <sql> is any SQL statement that will work against your Oracle instance, <host> is the database server, <database> is the Oracle instance, <username> and <password> give you access to Oracle. (DON'T type the chevons <> - I just included them for illustration.)
If that won't connect, change the name of classes12.zip to classes12.jar and try again.
This WILL work. - MOD

Seeking for jdbc drivers for oracle

I am new to java. I want to connect java with oracle databases(8i or 9i)
but don't know the driver name and how to use it, and from where i can
download it for free...

Hi ,
To connect to Oracle U certainly need the Thin Driver classes12.zip in the ClassPath . And here is the code Example .
import java.sql.SQLException;
import java.sql.Connection;
import java.sql.Statement;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import oracle.jdbc.driver.*;
import java.sql.DriverManager;
public class MyJdbc
public MyJdbc( int startPoint)
     try {
          Class.forName( "oracle.jdbc.driver.OracleDriver" );
     }catch(ClassNotFoundException nf)
          System.out.println("Clas Not Found" + nf.toString());
     try
          DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
          /* Connection */
             String      url="jdbc:oracle:thin:@10.236.148.52:1521:DPEG"; // Machine IP , POrt No and SID
          Connection con = DriverManager.getConnection(url , "username","pasword");
       String sqlString = "Select EName , Age , Dob From Emp ";
          Statement stmt = con.createStatement();
          ResultSet rs = stmt.executeQuery(sqlString);
           while(rs.next())
                    System.out.println("Name " + rs.getString("ENAME"));
                    System.out.println("Age " + rs.getString("AGE"));
                    System.out.println("Dob " + rs.getString("DOB"));
           rs.close();
           stmt.close();
           con.close();
    }catch(SQLException z)
      System.out.println("######" + z.toString());
      z.printStackTrace();

JDBC Connection for Oracle

Hello Experts,
I'm having some trouble getting a JDBC connection to work correctly and I am in need of some advice.
Background:
I have setup a test Portal 7.00 SP14 with an Oracle 10.2.0.2.0 database on a Windows 2003 X64 server. The Portal system was up and running and connecting to a WAS6.20 systems. We do not have BI or XI in our landscape.
I needed to connect to an Oracle 10.2.0.3.0 database from visual composer to read some data from tables to do a proof of concept. From what I understand this connection will be a JDBC connection. I have setup a new system using the JDBC template, assisnged an alias, and entered the connection URL . I was unable to connect.
I read that I need to add the driver using Visual Composer. I did so with the following instructions:
Install JDBC Driver
Start the Visual Administrator
Logon at WebAS
Open: Server, Services, JDBC Connector, Drivers
Choose Create New Driver or DataSource on the toolbar
Specify an arbitrary name for your driver entry such as OracleDriver and click OK
Now search for the Oracle JDBC Driver JAR file on your local harddisk.
I restarted the Java instance with SMICM after completing this task Java will not start. Is there anyway to roll back that change to get Java back up and running?
Also is there a better way to go about making this oracle connection?
Best Regards,

Hi,
although [this guide|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/92d80512-0a01-0010-32a3-cd3735bd9275] is for Visual Composer I find it very helpful in setting up JDBC connections to databases. There is a very deltailed section about setting up a system to a MS SQL Server and the relevant data if you want to connect to Oracle:
4.2 BI JDBC Connector to Oracle
Located at:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
Driver: oracle.jdbc.driver.OracleDriver
URL: jdbc:oracle:<drivertype>:@<database>
jdbc:oracle:thin:@myhost:1521:orcl
Hope this helps,
Holger.

Can someone checkout this JDBC code for me?

I'd be very grateful if an expert out there would check out my code for me, which I am about to use a great deal.
I've written this to save me some duplicated code, but since I haven't seen this approach much in my travels, I'm wondering if it has any particular flaws.
A separate DbAccess class is instantiated for any database access work, and once instantiated, getConnection is called and once finished closeConnection must be called.
You can get a ResultSet instance with just a little code and it's up to the calling programme to close it again.
The only things left open are the Statements, but they will get garbage collected or at any rate will be closed with the connection (whichever is sooner).
Is there anything wrong with this code?
import java.sql.*;
import javax.naming.*;
import javax.sql.*;
public class DbAccess{
     * The chosen datasource for this instance of the class
    private String dataSource;
     * The connection held in this instance (created by calling getConnection())
    private Connection con;
     * Instantiates a DbAccess instance, setting the datasource
    public DbAccess(String datasource){
     this.dataSource = dataSource;
     * Gets a connection to the database chosen in constructor parameter:
     * NB The calling programme MUST call closeConnection() after it's finished with it!
    public void getConnection()
     throws NamingException,
            SQLException{
     Context ctx = new InitialContext();
     DataSource ds = (DataSource)ctx.lookup(dataSource);
     con = ds.getConnection();
    }//end getConnection()
     * Closes the connection previously obtained with getConnection(), this MUST be called when the calling
     * programme has finished using the database.
    public void closeConnection()
     throws SQLException{
     con.close();
    }//end closeConnection()
     * Returns a ResultSet for a simple query, using a plain Statement
     * @param query - the complete database query
     * @return ResultSet for the query in the parameter
     * N.B. The calling programme MUST close the ResultSet after it's finished with it!
    public ResultSet getResultSet(String query)
     throws SQLException{
     Statement stmt = con.createStatement();
     ResultSet rs = stmt.executeQuery(query);
     return rs;
    }//end getResultSet()
     * Returns a ResultSet for a simple query, using a PreparedStatement, and accepting
     * a String parameter that can contain a String for a single setString().
     * @param query - the complete database query
     * @param stringToSet - the String for the preparedStatement's setString() method
     * @return ResultSet for the query in the parameter
     * N.B. The calling programme MUST close the ResultSet after it's finished with it!
    public ResultSet getResultSet(String query, String stringToSet)
     throws SQLException{
     PreparedStatement ps = con.prepareStatement(query);
     ps.setString(1,stringToSet);
     ResultSet rs = ps.executeQuery();
     return rs;
    }//end getResultSet()
}//end class

Ok, guys you've thoroughly trashed my code, fine, and
I half expected it because there's nothing like this
code about the placeYou're suffering from delusions of grandeur. There are plenty of approaches to that particular itch. The closest to what you're trying to achieve would probably be Spring's JDBCTemplate:
http://www.springframework.org/docs/api/org/springframework/jdbc/core/JdbcTemplate.html
Hibernate, iBatis, EJB3, and myriad others tackle the issue in other ways.
, but are we therefore concluding
that reducing the jdbc code is virtually impossibile
- and there's an awful lot of it every time you want
to do a query?My major objection to your approach is that you introduce a variety of bugs without significantly reducing the amount of JDBC code required. Most of what you're after in your class can be achieved by a convenience method to acquire the Connection object.
1) If (ok maybe it's a big if) - if I always close
the connection, the statements aren't being leaked
right?Not necessarily. To the best of my recollection the spec doesn't mandate this. And even if it does I've certainly encountered drivers that don't clean up statement resources that aren't explicitly released. So there's a theoretical and practical aspect to this.
2) I'm using Tomcat datasources, for getting the
connection, and I thought that you just had to call
con.close() for it to return to the pool. Am I wrong
on this?No, you're right - but nothing in your class prevents the user from calling getConnection twice and leaking a connection - the least you could do in the circumstances is prevent that by throwing an exception if they try.

How to get full source code for Oracle ADF?

Hi,
I 'm referring to the following URL http://download-west.oracle.com/docs/html/B25947_01/intro003.htm and it has mentioned that full source for Oracle ADF is available :
"Full source for Oracle ADF is available to supported customers through Oracle Worldwide Support. The full source code for the framework can be an important tool to assisting you in diagnosing problems and in correctly extending the base framework functionality for your needs."
Does anyone know how to obtain such information from Oracle support? Is this from metalink

One possible snag in the process is that you will have some legal paperwork to sign. Depending on your company's policies, this could pose a problem.
