Dear all, now I am create a dababase application. My database use JData Store. But I don't know how to connect application with it. Can you tell me this proplem?
Thank!

Do a google search for JDBC, or go buy a book.
You will need a JDBC driver which supports your database. Or you might be able to use the JDBC-ODBC bridge if there's an ODBC driver for your database.

How to connect webdynpro application to database (Sql server)

Hi Experts,
Can someone suggest me how to connect webdynpro application to SQL Server. (Possibly in detail)
Thanks Regards,
Sandeep

hi sandeep,
here is a sample code which connects to a backend database Oracle; Connection is same for all DBs as you are using open sql commands.
 try {
 String eposta = wdContext.currentContextElement().getEposta();
 String tel = wdContext.currentContextElement().getTelefon();
 String company = wdContext.currentContextElement().getCompany();
 String message = " ";
 String onerikonusu = " ";
 String oneri_mdurum = " ";
 String oneri_odurum = " ";
 String oneri_bfaydalar = " ";
 String oncelik1 = " ";
 String uygulama = " ";
 String tarih = (new SimpleDateFormat("dd-MM-yyyy").format(new java.util.Date()));
 String saat = (new SimpleDateFormat("HH:mm:ss").format(new java.util.Date()));
 //java.sql.Date tarih = java.sql.Date.valueOf(creationDate);
 //java.sql.Time saat = java.sql.Time.valueOf(creationTime);
 if (wdContext.currentContextElement().getMesaj() != "")
 { message = wdContext.currentContextElement().getMesaj(); }
 if (wdContext.currentContextElement().getOneri_konusu() != "")
 { onerikonusu = wdContext.currentContextElement().getOneri_konusu(); }
 if (wdContext.currentContextElement().getOneri_mdurum() != "")
 { oneri_mdurum = wdContext.currentContextElement().getOneri_mdurum(); }
 if (wdContext.currentContextElement().getOneri_konusu() != "")
 { oneri_odurum = wdContext.currentContextElement().getOneri_odurum(); }
 if (wdContext.currentContextElement().getBekfaydalar() != "")
 { oneri_bfaydalar = wdContext.currentContextElement().getBekfaydalar(); }
 if (wdContext.currentContextElement().getOncelik() != "NULL")
 { oncelik1 = onceliktxt.toUpperCase(); }
 if (wdContext.currentContextElement().getUygulama() != "NULL")
 { uygulama = app.toUpperCase(); }
 InitialContext ctx = new InitialContext();
 javax.sql.DataSource ds =
 (javax.sql.DataSource) ctx.lookup("jdbc/SAPEPPDB");
 java.sql.Connection con = ds.getConnection();
 con.setAutoCommit(false);
 java.sql.Statement stmt = con.createStatement();
 String sql;
 int rows;
 sql = "insert into tmp_feedbacks " +
 "(puid, name, tel, email, company, konu, oncelik, uygulama, mesaj, onerikonusu," +
 "oneri_mdurum, oneri_odurum, oneri_bfaydalar,tarih,saat) " +
 "values ('" + username + "', " +

 "'" + oneri_mdurum + "', " +
 "'" + oneri_odurum + "', " +
 "'" + oneri_bfaydalar + "', " +
 "'" + tarih + "', " +
 "'" + saat + "' " +
 stmt = con.createStatement();
 rows = stmt.executeUpdate(sql);
 con.commit();
 stmt.close();
 catch(Exception e){
 IWDMessageManager msgMgr =
 wdComponentAPI.getMessageManager();
 msgMgr.reportException(e.getMessage(),true);
 }
The value ctx.lookup("<jdbc_pool>"); depends on your system id.
if your system id is SID the the string has to be jdbc/SAPSIDDB
you can check it via visual admin >> server >> services >> jdbc con.

How to connect Java Application to ORACLE8i over SSL connection

Hi,
I would like to know how to make an existent Java application connect to an ORACLE8i database over a secure SSL connection?
can I user ResultSets?
Could you please tell me what parameters to set on the database and, especially, what new code must be added for the Java Application so send data over an SSL connection.
Your advice/hints will be greatly appreciated.
Vani

Use usual Oracle' encryption. SSL configuration is a nightmare.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());

Normally, if you are executing the client from the command line, you do not specify the classpath in a XML file (unless you are using ant or something similar). You can specify the classpath by using the -classpath option.
Try something like
java -classpath <path_to_jboss>/client/jbossall-client.jar;Betting_server.jar BettingServer
You can check the classpath in your client with the statement
System.out.print(System.getProperty("java.class.path"));

How to connect to a remote database in a lan??

Hey guys......! I need to connect to a remote msaccess database in a lan and import its data into my mysql database.I know how to connect to a msaccess database using ODBC.But I don't know how to connect to a remote database without creating dsn in the machine where database is.One thing more...I want to know, how can I import data into my mysql database?? Is there any query for that or simply I have to select data from msaccess database and insert into tables of my database??Please, send me the source code in the forum itself and explain also.This is the last feature of my project.So I need to do it as soon as possible.

If the mdb file in LAN, Just map the network drive.[Windows Explorer/Tools/Map Network Drive] in your system from which we need to access the remote mdb. Then go to ODBC Data Source Admin.. and create a new data source[Microsoft Access Driver] . After clicking the Select button, you will find a Network Drive will be visible on your Drives drop down. Select the map Drive, If not visible then just click the Network button there and map the network path where the mdb files reside. And use the JdbdOdbcDriver class to connect from java.
