Java applet to connect to Oracle Database?

Hello,
I need to make a standalone java applet where I can enter the following:
database url:
driver:
database:
user name:
password:
host name:
port:
and then click "ok" and it is supposed to connect me to my Oracle account set up at my school. Ive never done anything like this before. Can anyone please provide me with some code to get started? Thank soooo much!

look into jdbc. You will find it a bit more tricky if you insist on using an applet (why not an app?), as they do not by default have permission to do this sort of stuff (security issues). You will need to create the applet, and then sign it using a certificate. You may be able to get a development-only certificate for free from some eastern european website... I would strongly urge you to use an app instead if you are in any way able to.

ODI topology connection error - oracle database

Hi,
I'm trying to connect to oracle database installed on a remote server through odi client installed on my windows machine. Oracle db is on RHEL 64 bit, I believe. I know the connection details such as hostname, sid etc but i'm not able to establish a connection using the oracle jdbc driver. I can perfectly connect to the db via sqldeveloper using tnsnames and also basic connection which rules out the possibility that i might be giving incorrect SID name in ODI connection since I'm using the same details for both
Error which i received is:

tnsping works fine. To solve the problem, I changed my JDBC connection string to another format which uses connect description with service name and that solved the problem. This is what I used.
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on) (ADDRESS=(PROTOCOL=TCP)(HOST=) (PORT=1521)) (ADDRESS=(PROTOCOL=TCP)(HOST=) (PORT=1521)) (CONNECT_DATA=(SERVICE_NAME=)))

How to connect to Oracle database from webdynprojava application

Hi
How to connect to Oracle database from webdynprojava application. where can we provide the code to connect to database.?
Thank You.

Hi,
You need to create Java Bean model. The bean is a typical java bean with default constructor, getter and setter. You can have additional methods for query etc. The attributes in the class will be your model node and attributes.
However you need to configure the connection and create JNDI using visual administrator before writing the code.
You can also consider writing Session EJB with oracle and using them in WD.

Java Class to connect to oracle

Hi all,
I am a new in Java in database...
I have written a java class to connect to oracle and to get some information from the databse. In the class i use the driver oracle.jdbc.driver.OracleDriver.
When I exeute the code in JDeveloper it works fine.
I have loaded the classes to database (10gR2), have written the wrapper function. That all was compilled without errors.
But when I execute the wrapper function I get in SQL*Plus my custom Error-Message from Java Code "Not able to connect to oracle".
The oracle driver classes are owned by sys. Should SYS grant to the user any special rights with dbms_java.grant_permission?
Or is it any other way to connect to the database, in which the java classes are loaded? The user is connected with SQL*Plus. The Java Classes are owned by the user. Should I use JDBC to connect to the same database?
Best regards,

Hi
You don't need to re-connect... Have a look here...

Passing Array of java objects to and from oracle database-Complete Example

Hi all ,
I am posting a working example of Passing Array of java objects to and from oracle database . I have struggled a lot to get it working and since finally its working , postinmg it here so that it coudl be helpful to the rest of the folks.
First thinsg first
i) Create a Java Value Object which you want to pass .
create or replace and compile java source named Person as
import java.sql.*;
import java.io.*;
public class Person implements SQLData
private String sql_type = "PERSON_T";
public int person_id;
public String person_name;
public Person () {}
public String getSQLTypeName() throws SQLException { return sql_type; }
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
person_id = stream.readInt();
person_name = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeInt (person_id);
stream.writeString (person_name);
ii) Once you created a Java class compile this class in sql plus. Just Copy paste and run it in SQL .
you should see a message called "Java created."
iii) Now create your object Types
CREATE TYPE person_t AS OBJECT
EXTERNAL NAME 'Person' LANGUAGE JAVA
USING SQLData (
person_id NUMBER(9) EXTERNAL NAME 'person_id',
person_name VARCHAR2(30) EXTERNAL NAME 'person_name'
iv) Now create a table of Objects
CREATE TYPE person_tab IS TABLE OF person_t;
v) Now create your procedure . Ensure that you create dummy table called "person_test" for loggiing values.
create or replace
procedure give_me_an_array( p_array in person_tab,p_arrayout out person_tab)
as
l_person_id Number;
l_person_name Varchar2(200);
l_person person_t;
l_p_arrayout person_tab;
errm Varchar2(2000);
begin
     l_p_arrayout := person_tab();
for i in 1 .. p_array.count
loop
     l_p_arrayout.extend;
     insert into person_test values(p_array(i).person_id, 'in Record '||p_array(i).person_name);
     l_person_id := p_array(i).person_id;
     l_person_name := p_array(i).person_name;
     l_person := person_t(null,null);
     l_person.person_id := l_person_id + 5;
     l_person.person_name := 'Out Record ' ||l_person_name ;
     l_p_arrayout(i) := l_person;
end loop;
p_arrayout := l_p_arrayout;
     l_person_id := p_arrayout.count;
for i in 1 .. p_arrayout.count
loop
insert into person_test values(l_person_id, p_arrayout(i).person_name);
end loop;
commit;
EXCEPTION WHEN OTHERS THEN
     errm := SQLERRM;
     insert into person_test values(-1, errm);
     commit;
end;
vi) Now finally create your java class which will invoke the pl/sql procedure and get the updated value array and then display it on your screen>Alternatively you can also check the "person_test" tbale
import java.util.Date;
import java.io.*;
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.driver.*;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class ArrayDemo
public static void passArray() throws SQLException
Connection conn = getConnection();
ArrayDemo a = new ArrayDemo();
Person pn1 = new Person();
pn1.person_id = 1;
pn1.person_name = "SunilKumar";
Person pn2 = new Person();
pn2.person_id = 2;
pn2.person_name = "Superb";
Person pn3 = new Person();
pn3.person_id = 31;
pn3.person_name = "Outstanding";
Person[] P_arr = {pn1, pn2, pn3};
Person[] P_arr_out = new Person[3];
ArrayDescriptor descriptor =
ArrayDescriptor.createDescriptor( "PERSON_TAB", conn );
ARRAY array_to_pass =
new ARRAY( descriptor, conn, P_arr);
OracleCallableStatement ps =
(OracleCallableStatement )conn.prepareCall
( "begin give_me_an_array(?,?); end;" );
ps.setARRAY( 1, array_to_pass );
     ps.registerOutParameter( 2, OracleTypes.ARRAY,"PERSON_TAB" );
     ps.execute();
     oracle.sql.ARRAY returnArray = (oracle.sql.ARRAY)ps.getArray(2);
Object[] personDetails = (Object[]) returnArray.getArray();
Person person_record = new Person();
for (int i = 0; i < personDetails.length; i++) {
          person_record = (Person)personDetails;
          System.out.println( "row " + i + " = '" + person_record.person_name +"'" );
                    public static void main (String args[]){
     try
                         ArrayDemo tfc = new ArrayDemo();
                         tfc.passArray();
     catch(Exception e) {
                    e.printStackTrace();
          public static Connection getConnection() {
     try
                         Class.forName ("oracle.jdbc.OracleDriver");
                         return DriverManager.getConnection("jdbc:oracle:thin:@<<HostNanem>>:1523:VIS",
                         "username", "password");
     catch(Exception SQLe) {
                    System.out.println("IN EXCEPTION BLOCK ");
                    return null;
and thats it. you are done.
Hope it atleast helps people to get started. Comments are appreciated. I can be reached at ([email protected]) or [email protected]
Thanks

Hi Sunil,
I've a similar situation where I'm trying to insert Java objects in db using bulk insert. My issue is with performance for which I've created a new thread.
http://forum.java.sun.com/thread.jspa?threadID=5270260&tstart=30
I ran into your code and looked into it. You've used the Person object array and directly passing it to the oracle.sql.ARRAY constructor. Just curios if this works, cos my understanding is that you need to create a oracle.sql.STRUCT out of ur java object collection and pass it to the ARRAY constructor. I tried ur way but got this runtime exception.

Here's a code snippet I used :
Object optionVal[] =   {optionArr[0]};   // optionArr[0] is an Option object which has three properties
oracle.sql.ArrayDescriptor empArrayDescriptor = oracle.sql.ArrayDescriptor.createDescriptor("TT_EMP_TEST",conn);
ARRAY empArray = new ARRAY(empArrayDescriptor,conn,optionVal);If you visit my thread, u'll see that I'm using STRUCT and then pass it to the ARRAY constructor, which works well, except for the performance issue.
I'll appreciate if you can provide some information.

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

Help needed in connecting to oracle database in unity

Hi,
I have been trying to connect to Oracle database in my codes. I have tried using OdbcConnection and OleDbconnection. But both did not allowed me to connect to the database. The database, testDb, can be accessed using SQL plus as well as the SQL developer. I even tested the connection successful using ODBC data source administrator.
the following is my code for the connection string:
OdbcConnection connectionString = "Driver={Oracle ODBC Driver};Server=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP )(HOST=127.0.0.1)(PORT=1521))(CONNECT_DATA=(SID=Te stDb)));Uid=scott;Pwd=password;";
the error i got is [ODBC Driver Manager] Data Source name not found and no default driver specified.
for the driver parameter, i have tried using "Microsoft ODBC for Oracle". It gives me another error stating that the oracle and network components are not installed.
I even tried "Oracle in OraDb11g_home1" which was specified in the ODBC Data Source Administrator. The same error came out.
Below are some of my specifications:
Platform: Windows 7 64bit
Oracle: Oracle Database 11g Release 2 (64bit)
Unity: 4.1.2
Can someone please help me with this? What is it that i have done wrong?
Thanks.

whenever localhost (127.0.0.1) is used, this means that no remote client can ever connect to this system
The problem involves ODBC configuration & has nothing to do with Oracle.

I am able to connect to the database using SQL*Plus with the same credentials.
Any help is appreciated!

I take it you solved this problem, since you posted this: installing Oracle 10.1.0.2.0 (32 bit) on windows 2003 server

Pls help thanks in advance.

There are 2 places you need to keep TNS names.ora file for OBIEE to connect.
1. Oracle client which is in your machine
2. OBIEEhome>Oracle_BI1\network\admin
I'm sure you would have it in your oracle client. Copy paste the same TNS names in this path too.
Then open rpd and right click on any table in physical layer and click view data. You should see the results.
if this doesn't work check your credentials.
mark if this helps

Issues when trying to connect to Oracle database

Hi
We have set up a linked server in SQL Server to connect to an Oracle database. We are using SQL Server 2008 R2 Enterprise (64 bit) on Windows Server 2008 and Oracle client 11g 11.02.00.01 connecting to Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production using UTF8.
Most tables are selectable without error, however, we got this error message for some:
Msg 7347, Level 16, State 1, Line 1
OLE DB provider 'OraOLEDB.Oracle' for linked server 'OurLinkedServer' returned data that does not match expected data length for column '[OraOLEDB.Oracle].Ourfieldname'. The (maximum) expected data length is 6, while the returned data length is 2.
This error message refers to a column of type char(3)
Will the characterset cause this error (I’ve read that SQL Server doesn’t support UTF8)?
If not, is there some other resolution that anyone can think of?
Any suggestions are greatly appreciated.
Thanks a lot!
Tom

Thank You for replying, Justin!
Yes, I can connect successfully to the database through other tools - at the moment I tried SQL*Plus, Net8 Easy Config and Schema Manager.
The Oracle client in the NT machine is 8.0.5.0.0. And unfortunately I do not know anything about the Oracle installation on this machine and at the moment I don't have that person near me too whom to ask also. But I think the installation was ok, because the connection through ODBC was working before the DB upgrade as far as I understood (sorry, again at the moment I don't know what was the previous version of DB. I will ask that information as soon as possible).
The main problem that bothers me at the moment is that I can't install 8.1.* series OraODBC driver with 8.0.5.0.0 Oracle Installer. I managed to install 8.0.6.6.0 version of the driver, but not the newer ones. As far as I've understood I have to upgrade the whole Oracle in the NT machine to upgrade that installer. Am I correct?

How to connect to oracle database from visual basic 2010 express edition

I have installed visual basic 2010 express edition on windows xp. But visual basic 2010 express edition supports Microsoft sql server database file,Microsoft sql server compact 3.5, Microsoft access database file. I want to connect to oracle database from visual basic 2010 express edition. So what drivers are required and how to do connectivity?

Hello,
I wasn't clear on what you were using to make the connection. I had a look in Visual Studio 2010 (don't have express to test sorry).
I think you mean the Data Sources available under the menu Data-> Datasources. this seems to match the description you give when I
look at the list of datasource options.
In here you can make ODBC connections via the Microsoft .net Data Provider .
If you select ODBC as a datasource you can see listed the DSN's you created - for example I see 2 which use the Oracle ODBC driver.
This assumes you installed an Oracle Client + the oracle version of the ODBC driver (comes with the oracle client).
Once you created a server connection then you should see it in the server explorer.
You can also download the Oracle Developer Tools for Visual Studio which is an add on for VS.
** I suspect this is only for VS 2010 and I didn't see that Express was supported.

Let me know if that helps.

Cannot connect to Oracle database from SQL Server

Hi
We have set up a SQL Server linked server and tried to use this SQL Server linked server to connect to Oracle database. We are using SQL Server 2008 and Oracle client 11g 11.02.00.01. However, we got this error message:
Msg 7347, Level 16, State 1, Line 1
OLE DB provider 'OraOLEDB.Oracle' for linked server 'OurLinkedServer' returned data that does not match expected data length for column '[OraOLEDB.Oracle].Ourfieldname'. The (maximum) expected data length is 6, while the returned data length is 2.
We are able to connect some of the tables ok but some of the tables are not connected and got the above error message.
Any suggestions are greatly appreciated.
Thanks a lot

Hi
Here is more information. We just found out that the Oracle database team changed the character set to something else and then they changed it back to UTF8.
Currently, it is using UTF8 character set on the Oracle side. Will this causing us this error message on our sql server linked server?
The error message said "The (maximum) expected data length is 6, while the returned data length is 2."
This refers to a field/column with char(1)
Any suggestions are greatly appreciated
Thank you
