Connectivity of database through applet

Hi to all,
I want to how to make the connectivity of database(preferably mySql) to java application through applet....

Possible answers to a more focused question:
Make sure the jar file containing the JDBC driver is in your applet's classpath.
Read the JDBC tutorial.
Make sure that the network connectivity between your client and the database is working.
Any of those sound right? No? Want to ask a more specific question?

}To give an applet special privileges you can specify the prifs in the java.policy file or sign the applet and choose "yes I trust" or "yes I allways trust" when the applet is loaded.
To give special prifs with the java.policy, it should look like this:
grant {
permission java.lang.RuntimePermission "usePolicy"; // prevents the popup from showing for signed applets
grant codeBase "file:C:/-" {
permission java.security.AllPermission;
grant codeBase "http://localhost/-" {
permission java.security.AllPermission;
};

How to connect 10g database through Enterprise manager???

Hi All,
I want to connect the database through Enterprise manager.
My database is on 10g. Version is 10.1
Please tell me the procedure to connect the database through E.M.
Thanks and Regards,
Prathamesh.

Are you thinking of the Enterprise Manager supplied with Oracle9i? If yes - it doesn't work quite that way ... and the 9i java OEM is not compatible.
Use the enterprise manager supplied with the 10g database, called the dbconsole (look for a service or start it using 'emctl start dbconsole') and access it using http://{localhost}:5500/em
If that doesn't satisfy you, load the updated version of the OEM 9i java standalone from the 10g client disk.

How to Connect MySQL Database Through JTable?

Hi,
How to Connect MySQL Database Through JTable? anyone of u knows these concept please send me coding of that Part..
Thanks,
Guru..

Start by reading the tutorials. There's a section on Swing which shows you how to use tables and a section on JDBC which shows you how to use SQL.
And you can always search the forum as well since there are working examples of both posted on the forum.
If you need further help with a specific problem then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the [Code Formatting Tags|http://forum.java.sun.com/help.jspa?sec=formatting], so the posted code retains its original formatting.

Connecting to database through Captivate?

Hello all...
I am using captivate4.
My question description: I have a requirement to connect to database through captivate(any version) & retrieve the data & . I have "N" number of categories in my course where the user will be given an option to select the category according to his preference. I would like to place the questions(category wise) in the data base (so that adding the additional questions would be more flexible) & would like to call it into Captivate quiz accordingly based on the user selection.
How is this possible?
Thanks & regards,
Pullela.

Have a look at Jim Leichliter's blog, if someone can do it it will be him:

How to connect Oracle database through Microsoft ODBC?

My ODBC Configuration:
DSN name is :db
Username : india
Server :db.world
Now, i am trying to connect with oracle database through SQL*plus or TOAD.
But, it is giving the following error.
ORA-03121: no interface driver connected - function not performed
Database version : 9.2.0.1.0
Operating System : Microsoft Windows XP
ODBC Version : 2.575.1117.00
I am trying to connect with the database like this:
Username : india
Password : india
Database : ODBC:db
Can i connect like this otherwise whether i need install any other supporting driver?

Now, i am trying to connect with oracle database
through SQL*plus or TOAD.
But, it is giving the following error.
ORA-03121: no interface driver connected -
function not performed
I am trying to connect with the database like this:
Username : india
Password : india
Database : ODBC:db
As already stated, you can not use the DSN in SQL*Plus (nor TOAD, afaik)!
I can reproduce the error message with the following:
C:\>sqlplus a/b@ODBC:c
SQL*Plus: Release 11.1.0.6.0 - Production on Mon Aug 4 21:34:58 2008
Copyright (c) 1982, 2007, Oracle. All rights reserved.
ERROR:
ORA-03121: no interface driver connected - function not performedLooking up the message, it says:
Cause: A SQL*Net version 1 prefix was erroneously used in the connect string
Looks like this has nothing to do with your DSN - it is more a matter of not using a proper connection string.
If 'Test Connection' works then you should probably proceed to work with Crystal Reports, using the DSN in question.
However, you should note that the old MS ODBC driver for Oracle was designed for OCI 7 (and for databases 7.x-8.x) and is now considered obsolete by both MS and Oracle.
Deprecated MDAC components and MS KB Article 244661.
Use the Oracle ODBC driver included with a supported Client version instead.
Edit:
Clarifying and adding references.

Go to System Administration
-> System Configuration
-> System Landscape
-> select a Folder where you want to store your system object
-> right click -> New System
-> in the wizard, select JDBC System
-> enter values
-> edit
Then fill in the correct values as stated here:
http://help.sap.com/saphelp_nw04/helpdata/en/84/d5df3df2ad685ae10000000a11405a/frameset.htm
Then assign an Alias and enter some usermapping data for the system.
You then can use the ConnectorService to get a native sql connection and fire statements. I'm sure you can find some examples here.

How to connect access database through oracle sql prompt

i want to connect access database via oracle , i am trying to import all the data in Access table into oracle table how it is possible .
A.R

The simplest way, if You have already created tables in Oracle DB, is to open the Access MDB, link Oracle tables via ODBC and build a query to append rows reading from Access tables to Oracle tables.
Hope this helps

Connecting Oracle DataBase through WebDynpro

Hi,
I created a Dynamic table, now I should display the data from Oracle Database. I tried in many various ways to connect to database, but the data is not retrieving.
Can u explain the reasons and give necessary coding to retrieve the data.
Its very very urgent.

Hi
I think you can do using the APIs provided by SAP.
Check this link
JDBC Reference
or
Try connectinc using lookup.
try{
InitialContext ctx=new InitialContext();
javax.sql.DataSource ds=(javax.sql.DataSource)ctx.lookup("jdbc/SAPJ2EDB");
java.sql.Connection con=ds.getConnection();
java.sql.Statement stmt=con.createStatement();
con.close();
catch(Exception e)
wdComponentAPI.getMessageManager().reportException("Exception "+e,true);

Visual Studio 2010 64bit cann't connect Oracle database through 64bit ODBC Driver

Hi,
I am developing an 64bit And-In software. My OS is windows7 64bit Ultimate. Developer tool is
Microsoft Visual Studio 2010 Ultimate 64bit any-CUP.
Server is SUN server and Oracle database 10.2.0.5 64bit enterprise edition.
I have installed instantclient-odbc-win64-10.2.0.5 on my computer.
I am able to connect through the command line sqlplus user/pass@server.
In date source(c:\windows\system32\odbcad32.exe), ODBC Driver connection successful.
But in VS2010 C#, use Tools -> Connect Database,I get an error 193 (Oracle in
instantclient10_2,c:\ora10_64\SQORA32.dll) cann't be loaded.
SQORA32.dll is 32bit ODBC Driver or 64bit ODBC Driver?
How can I connect database with vs2010 64bit?
Regards

There is no Visual Studio 2010 Ultimate 64bit as far as I know. It's a 32 bit app. Generally you'd need to install a 32 bit client to use the 32 bit tools.
Hope it helps,

Connect to Database through FORM builder

I have configured 2 listeners to my database, both connect to the database ok but when I try to connect through my form builder I keep getting the error message
"cannot resolve service_name" even though it's already connected through my net configuration assistant. Is there a seperate connect properties file for my form builder?

You need to add an entry in the tnsnames.ora file that is in the Oracle_home that Forms is in.

Thank you so much!
Jess

Thank you.
If i were to use a policy file... what should i do to let the browser know about that? Sorry i'm a completey idiot on this.
expected outcome:
typing an URL on the browser, say, http://abc.com/test.html --
an applet will load and the database in the root folder (applet is also in here) would be retrieved.
Thank you.
