Help connecting to SSM Database

Good day SSM Geeks,
Again another question..., hope you guys can help me.
How do I connect to SSM Database?
I need to extract a table with all the initiatives by context (containing: Owner (Team), Budget, Schedule, Target End, Comments, etc..)
We are developing a web solution to improve the Milestones and Sub-milestones of initiatives component.
Again, any help with it, Iu2019ll appreciate.
Frederick

Hi
1.- Try to type MSTSC in Windows Execute Command (Run window)
2.- Name of remote desktop -> connect
3.- Username and Password required (probably the same you are using as administrator)
4.- Once in remote desktop, open Application Server Administration. You should see all tables, processes...
I hope it helps

Need help connecting to a database with an applet

I am making a Java game that runs in an applet and needs to connect to a Java DB database. I created the database and table in NetBeans and now I have no idea how to connect this applet to the database. I tried using a DataSource and an InitialContext and I got a NoInitialContextException. Any help would be appreciated thanks.

Already made the InitialContext. This is the code I used in the applet:
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("jdbc:derby://localhost:1527/GameDatabase");
Connection con = ds.getConnection();
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM Scenery");

Newby Needs Help Connecting to Oracle Database

I'm very very new to java. I'm trying to write a program to connect to and read some fields in an oracle table. I'm having problems and am not sure how to correct it. I downloaded and installed the oracle thin driver. I'm using Eclipse 3.3 and JRE 1.6. This is my code:
import java.sql.*;
public class One {
     public static void main(String[] args) {
          try {
               DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
               System.out.println("let's connect");
               Connection conn=DriverManager.getConnection(
          "jdbc:oracle:thin:@a571p05.pt.com:1521:orap1","username","password");
                    System.out.println("I'm connected");
                    Statement stmt=conn.createStatement();
                    ResultSet rset=stmt.executeQuery(
                         "select CUSTNUM,CUST_LNAME from TBL.CUSTOMER where " + "CUSTNUM=\"12345678900\"");
               System.out.println("Result set?");
               while (rset.next())
                    System.out.println(rset.getString(1)); //Print col 1
               stmt.close();
          catch(Exception x) {
               System.out.println("Unable to connect!");
          System.exit(0);
If I just run it, this is the output:
let's connect
I'm connected
Unable to connect!
So, it looks like it may be connecting, at least it runs the line that establishes the connection then the next line which prints a comment. However, it seems to fail at some point thereafter. I've tried debugging it and as far as I can tell, it's erroring out on thie line:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
with this stack trace:
Thread [main] (Suspended)

I checked the project properties\java build path and I have JDBC_THIN_DRIVER and JRE_SYSTEM_LIBRARY listed there. Do I need something else? I'm not quite sure what I'm missing or what the errors are telling me. Any help, or pointers are appreciated. Thanks much!

I would write that class more like this, assuming that customer ID is a String:
import java.sql.*;
public class One
   private static final String DEFAULT_DRIVER = "com.oracle.jdbc.Driver";
   private static final String DEFAULT_URL = "jdbc:oracle:thin:@a571p05.pt.com:1521:orap1";
   private static final String DEFAULT_USERNAME = "username";
   private static final String DEFAULT_PASSWORD = "password";
   private static final String SQL = "select CUSTNUM,CUST_LNAME from TBL.CUSTOMER where CUSTNUM=?";
   private static final String DEFAULT_CUSTOMER_ID = "12345678900";
   public static void main(String[] args)
      Connection conn = null;
      PreparedStatement stmt = null;
      ResultSet rset = null;
      try
         Class.forName(DEFAULT_DRIVER);
         conn = DriverManager.getConnection(DEFAULT_URL, DEFAULT_USERNAME, DEFAULT_PASSWORD);
         stmt = conn.prepareStatement(SQL);
         String customerId = ((args.length > 0) ? args[0] : DEFAULT_CUSTOMER_ID);
         stmt.setString(1, customerId);
         rset = stmt.executeQuery();
         while (rset.next())
            System.out.println(rset.getString(1));
      catch (Exception x)
         x.printStackTrace();
      finally
         close(rset);
         close(stmt);
         close(conn);
   private static void close(Connection conn)
      try
         if (conn != null)
            conn.close();
      catch (SQLException e)
         e.printStackTrace();
   private static void close(Statement stmt)
      try
         if (stmt != null)
            stmt.close();
      catch (SQLException e)
         e.printStackTrace();
   private static void close(ResultSet rset)
      try
         if (rset != null)
            rset.close();
      catch (SQLException e)

Dw cs5 with existing wordpress site hosted on yahoo need help connecting to existing remote database

I am having trouble establishing a database connection. I can connect with test databases but am having trouble using dreamweaver wtih my existing wordpress website. Am I able to use dreamweaver to edit and live view my changes before uploading the changed files to my live site? Am I able to access my existing wordpress database with dreaweaver? I have imported it to my testing server/database but still seem to be having trouble establishing a connection with it (think maybe my folder hierarchy might be off).
macintosh HD/Applications/MAMP/htdocs/nwm/wp/index.php
"nwm" is the name of the folder that I have copied all of my site files to and the folder I have dreamweaver pointing to. "wp" is what I have all of the wordpress files in (the ones I copied from my yahoo server - including all my current theme files etc.)
I am trying to put the info into the mysql connection dialog box:
Connection Name: Testing (i am assuming this name is for my benefit only and doesn't actually matter)
MySQL Server: mysql
User Name: *****
Password: *****
Database: wp
and am getting this message
MySQL Error#: 2013
Lost connection to MySQL server at 'reading initial communication packet', system error 61
did some google seaches of the error. Tried turning off the firewall, and the advance tab allow mysql incoming (there were 2 one was allow one was not allow. I changed both to allow)
Cant really find anything on yahoo to help me out. Looked in phpmyadmin database named wp: wp_users to get the username and password (which due to previous look for help - I think the password was encrypted cuz it looked like a bunch of mumbo jumbo and am fairly certain I know the correct password).
Any help would be greatly appreciated!! I spent $50 on live chat last night trying to resolve the issue only to find out at the end that the guy really didn't understand my problem and doesn't have dreamweaver. I have also watched countless videos on Lynda.com and have been thru forum after forum. While this problem is only a couple weeks old since I just got CS5. I have been having trouble making any headway learning php since I cant seem to make it past the set up parts. I have done the php / mysql essential training on lynda.com with relative success except that I really dont want to work with any more exercise files so I didn't go on to the beyond the basics. I recently went thru most of the Dreamweaver CS5 and Wordpress 3. Also did the first 4 chapters of Dreamweaver CS5 with PHP and MySQL. I need to start integrating things into my live sites. I am also trying to work my way thru the learning php, mysql, javascript book by o'reily media by robin nixon (as fun as reading a math text book) can't get thru it since I can't relate any of it to my current sites/needs
I am on MacBookPro OSX 10.6.6
Installed MAMP to specification on all 20 tutorials I have tried including lynda.com
Tested the testing server and is working
Just installed dreamweaver cs5
have been using wordpress online to create and edit posts (recently upgraded to 3.? whatever the latest update was online which I believe update the files on my yahoo server?)
Have also installed wordpress on my computer (several times thru each tutorial trying to get this right.)
Am I expecting the impossible?

If wordpress controls it's own connection why am I unable to use the live view. I have synced the remote site to my local computer so all the files should be just as they are online with the exception of the DB which contains most of the content.
I have done all of those steps. I have even exported the database from inside internet phpmyadmin and imported into computer phpmyadmin. When I hit live view I get one of couple of errors.
1. "One is that the dynamic related files could not be displayed due to an internal server error"
At some point I was able to view some sample files inside dreamweaver. But I would like to be able to view my real site files. I was able to "connect" to the local databases (not the copy of my real one - I think that maybe that was because it is somehow nested inside another db an am going try to reimport to new location). And then I changed the host/username/password trying to deal with the internal server error. Now instead I get the cannot connect to the database Error 2016 or whatever from the origianl post. Also, I am using yahoo if that matters and all I can find about what their server name is: mysql - is that correct?
I have been thru this so many times with so many different tutorials I am losing track of what is what.
2. Can I access my remote database within dreamweaver? I do not want to create dummy files (seems to be a waste of time). And while if it had worked exporting/importing a duplicate on to my computer would have satisfied me for a little while it also seems some what counter productive. Since every post and page is different if I were doing a daily updates etc how would I be able to change the formating or design of them if I can't access the remote files. Would I re- import everytime I want to work on it to get current database?
I am trying to be clear. I listed all the specs I could think as listed in your "how to get help fast post" (yes I read that at least twice too) of all of the steps and possible reasons for my problems. I also thought that the forum was on a seperate site so I didn't think it would count as a duplicate. I am frustrated to tears and am feeling incredibly stupid that after all this time and all these tutorials yes you are right I obviously am not understanding what is going on which is why I am on this forum.

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.

First you need to make sure you have the proper OBDC driver installed so Windows knows where to look. What OS is on your desktop?

Need help connecting to database on website!!!!

Hi there
I am doing a school project and have decided to make a database which i can store user info and car info (its a car auction program)
But i am having trouble with the connection to the database... we have been told to use jdbc odbc connection so is there a way to use this method to connect to my database?
this is my connection code when connecting to the database locally:
con = DriverManager.getConnection("jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=CarDealership.accdb");
i omitted the other code because it is pretty standard code to do this connection.
But now i want to connect to a database of the same name on this site:
sites.google.com/site/card3al3rsh1p
what must i change in my code to be able to connect to the database on the internet????
please please plssssssss help me really want to get this to work
thanks and regards

OK I apologise and realise I was in a rush. I will try explain more clearly now.
I am using Netbeans 7 and am having troubles connecting my java program to a Microsoft Access database which is on this website:
sites.google.com/site/card3al3rsh1p/
The database name is "CarDealership.accdb".
When I use the class below to connect to my database locally, it is a success.
import java.sql.*;
public class DB {
Connection con;
Statement stm;
ResultSet rs;
public DB(){
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection("jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=*CarDealership.accdb*");
} catch(Exception ex){
System.out.println("Error opening database.");
System.out.println(ex);
System.out.println("Database successfully opened.");
However, when I change the bold text above (or the text between the asterisks, not sure if it will change) to "sites.google.com//site//card3al3rsh1p//CarDealership.accdb" it throws an error signifying that it can't find the file specified.
I am unsure of how to connect my program to an external file so I need assistance in how to change the url String of the DriverManager.getConnection() method above so it can connect to the database on the website mentioned above. I would appreciate it if you could assist and thanks.

Connecting to a database on another machine, please help!!!!!!

Hi there,
I am new to oracle and at the minute I am using Oracle 9i. I have set up a database on one machine (PC2) and would like to create an odbc from another machine (PC1) to connect to this database. I have set up a listener for (PC1) the using oracle net manager on PC2. what I want to know is: is there anything else I need to do on the PC2 end???? Also, what needs to be done on the PC1 end??? please help!!!

If everything is setup and working properly on the Server PC2, you can just test the ODBC from PC1 (assum you already have an Oracle ODBC drive).

And i see another thing that confuses me. Your URL connection string is
con = DriverManager.getConnection("jdbc:mysql://localhost:8080/own"); meaning that your database is in your machine and listens in port 8080 for incoming connections. But that is the default port that Tomcat listens! Maybe you should change this line to
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/own");where 3306 is MySQL's default port.
Hope these help.

Help using C# application to connect to oracle database

I'm new to database.
I'm developing a C# GUI application in visual studio 2008 that is suppose to interact with oracle. After researching and trying out several sample codes, nothing works and I'm in desperate need of some help/advice/suggestions.
The simplest example I'm trying is to just get a button to run a simple SQL query. The code is:
private void button1_Click(object sender, EventArgs e)
string oradb = "Data Source=acme.gatech.edu;User Id=gtg880f;Password=******;";
OracleConnection conn = new OracleConnection(oradb); // C#
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = "select Location_Name from warehouse where Location_name = 'atlanta'";
cmd.CommandType = CommandType.Text;
OracleDataReader dr = cmd.ExecuteReader();
dr.Read();
label1.Text = dr.GetString(0);
conn.Dispose();
I've installed many many version of oracle database and have included the Oracle.Data.Access under reference.
If I use putty and connect to acme.gatech.edu via port 22, I can type sqlplus / and run the query "elect Location_Name from warehouse where Location_name = 'atlanta'" and it'll work.
After some research, some say that if I can connect via sqlplus that means i can connect to the database but what do i need to implement to enable my c# code in visual studio to be able to do that.
I did a search on the forum but found nothing that matches this. In essence, I'm not sure what/how to specify such that I can connect to the acme.gatech.edu server and run sql commands.
Thanks,

There're two ways you can get data in and out of database using .NET
#1 System.Data.OracleClient namespace - it's .NET avail out of the box
#2 Oracle.DataAccess.Client - aka "ODP.NET"
               Download: http://www.oracle.com/technology/software/tech/windows/odpnet/index.html
Or download Beta because as of today it's the only version which supports .NET "TransactionScope" (I just tested seems like still it is NOT working Re: 10g Express + ODP.NET (version 2.111.6.20) > support TransactionScope? http://www.oracle.com/technology/software/tech/windows/odpnet/index1110710beta.html
QuickStart: http://www.installationwiki.org/ODP.NET_Getting_Started_Guide
Also there's a doc under Start menu>Programs>Oracle - OraOdac11g_BETA_home>Application Development>"Oracle Data Provider for .NET Developer's Guide"
It's worth reading just scroll down quick for code fragment.
Anyway here's two small examples:
Example 1: System.Data.OracleClient (Using library from M$)
          * First you'll need to add reference to "System.Data.OracleClient".
          IDbFactory oDbFactory = DbProviderFactories.GetFactory("System.Data.OracleClient");
          IDbConnection oConn = oDbFactory.CreateConnection();
          oConn.ConnectionString = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;";
          // Or ...
          oConn = new System.Data.OracleClient.OracleConnection("Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;");
     Example 2: ODP.NET from Oracle
          IDbFactory oDbFactory = DbProviderFactories.GetFactory("Oracle.DataAccess.Client");
          IDbConnection oConn = oDbFactory.CreateConnection();
          oConn.ConnectionString = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;";
          // Or ...
          oConn = new Oracle.DataAccess.Client.OracleConnection("Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;");
string strSQL = "... SQL statement...";
          int nPersonId = 0;
          string strFirstName = null;
          Person oPerson = null;
          string strSQL = "SELECT Id FROM PERSON";
          oCmd = oConn.CreateCommand();
          oCmd.CommandText = strSQL;
          oCmd.CommandType = System.Data.CommandType.Text;
          IDataReader oRdr = oCmd.ExecuteReader();
          while (oRdr.Read())
               if (!Convert.IsDBNull(oRdr["Id"]))
                    nPersonId = (int) oRdr["Id"];
               if (!Convert.IsDBNull(oRdr["FirstName"]))
                    strFirstName = (string)oRdr["FirstName"];
               oPerson.Id = nPersonId;
               oPerson.FirstName = strFirstName;
Example CREATE TABLE:
          DECLARE
          count_item int;
          BEGIN
               SELECT count(1) into count_item FROM user_sequences WHERE sequence_name = 'AUDITLOGSEQUENCE';

Help Connecting A Stateless Session Bean To MySQL Database

Hi, I'm trying to connect a simple stateless session bean that has been
deployed using the admin console to a MySQL database that has been
set up and pinged using the JDBC Resources/Connection Pools part of the
admin console.
When I attempt to connect to the database using the session bean I get the
following error message:

Obviously this means that the bean can't connect to the database but I am
unsure why this is. When I set up the database using the admin console
I set the the jndi name to jdbc/test and I've tried using the following look up
code to find the database that is referenced by the JNDI name:
Context context = new javax.naming.InitialContext();
          DataSource ds = (DataSource) context.lookup("jdbc/test");
and also
Context context = new javax.naming.InitialContext();
DataSource ds = (DataSource)context.lookup("java:comp/env/jdbc/test");
Neither of these methods work.
When I look at the JNDI Tree Browsing window which is available from the
admin console there is no mention of the database at all, there are four
items in the three, they are:
UserTransaction
->jdbc
->ejb
DBBean
Do I need to add a JNDI reference somewhere in order for the bean to locate
the database? I thought that when I created the database in the admin
console and specified a JNDI name this would be all that's required in order
for beans to locate the database, obviously not.
If anyone can offer any advice at all I would be very very grateful.
Ian

stmt.execute("use YOUR_DATABASE_NAME");
// then your db queries.This approach works for me.
It also works to specify the database in the query like this:
InitialContext initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
DataSource ds = (DataSource) envCtx.lookup("jdbc/myDB");
Connection conn = ds.getConnection();
try {
       Statement statement = conn.createStatement();
       ResultSet rs = statement.executeQuery("select * from myDB.news");
       ...As you can see I added myDB. to the query.
But why is this necessary?
If I use DriverManager instead, this is NOT necessary. Like this:
Connection connection = null;
try {
       Class.forName("com.mysql.jdbc.Driver");
       connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/myDB", "username", "password");
       Statement statement = connection.createStatement();
       ResultSet rs = statement.executeQuery("select * from news");
       ...Why do I not have to run the query statement.execute("use YOUR_DATABASE_NAME"); or specify the database name in the query statement.executeQuery("select * from myDB.news"); when I use DriverManager to obtain a Connection when I have to do that when using a DataSource?
It don't seem very efficient to have to run the extra query ( use db-name ) before I run any other query in my application.

Pls help - cant connect to my database while my class is part of a package

Can anyone please tell me why one can't connect to a database, while the class is part of a package?
package Application;
import java.sql.*;
public class GameDatabase
GameDatabase ()
connect ();
public void connect ()
try
String url = "jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb)};DBQ=Profiles.mdb";
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
Connection dbcon = DriverManager.getConnection (url);
catch (ClassNotFoundException a)
System.out.println ("ClassNotFoundEx");
catch (SQLException e)
System.out.println ("SQLEx");
public static void main (String [] args)
new GameDatabase ();
gives a SQLexception while the "package Appplication;" is present,
yet works perfectly when its commented.
Any suggestions how to bypass this?

Well, it just cannot find the file? Maybe you've to supply a path?
Further on, one more lesson:
System.out.println ("ClassNotFoundEx");
System.out.println ("SQLEx");Please don't ignore exceptions. They are not intented for phun. Rather use e.printStackTrace();

SQL SEREVR CONNECTION TO LOCAL DATABASE FAILED ,help!!

Hai,
I detached my dev database from sql server 2000 enterprise manager and then i replaced my old data files mdf,ndf and ldf with the new once on the same location. now when i start sql server it is not showing any of databases , i also registered the sql server again and it gives me mesage can't connect to database login failed.
i think there must be some password at db level which is causing problem.
if i have to change the old password at this stage what should i do??
hope i find some solution
regards
jase

Hi,
you must logon with another user. Use a local admin. Logon on Windows with another local admin and connect to your SQl Server. Once you are connected attach the database again. Then you are able to connect via sidadm again.
The root cause is, that the default database of the sidadm is detached, so the sidadm cannot log on.
A second way can be to use the osql.exe tool. Open a command promt and run
osql -E -dmaster
This should you connect to the default instance of the server and switch to the master database, Then you can run
exec sp_defaultdb '<sid>adm','master'
go
Then you should be able to logon as sidadm as well.
regards
Clas
