Problem in Connectivity to Derby Database in Netbeans IDE

I am using the newest version of Netbeans IDE
I already set the variable for JAVA_HOME and DERBY_HOME along with the path variables.
I am trying to connect to Database in Network Mode
using the following code
try
Class.forName("org.apache.derby.jdbc.ClientDriver");
catch(ClassNotFoundException exception)
exception.printStackTrace();
but it is giving the runtime error that "Unable to load Driver"
Please help me to get through this

Try adding the following to your class:
import org.apache.derby.jdbc.ClientDriver;
If it produces an error, your driver *.jar file is not in the classpath.

  • Point Database tutorial but using Derby Database in NetBeans IDE

    Hi
    I am getting an error when I am trying to run the EJB Entity beans BMP example "savingsaccount" in the examples folder of j2eetutorials .
    I have using NEtBeans IDE + Sun APP server and the following the tutorial Netbeans + J2ee tutorials...
    THe problem is the tutorial talks about a "pointdatabase" 8.1 verson and the Sun App Server I have is 8.2 which has "Derby Database".
    However I made the necessary changes in the code. Siill the error is someting like this :

    ....and more...
    So I am not sure whether this is some fault of the application or the database access errior...?
    Someone who tried this let me know plz...
    thanks

    Microsoft SQL Driver 2005 JDBC Driver is not the Derby driver.
    You need the correct JDBC driver for the database you are using, you can't simply grab the first one you find.

  • Connecting to Derby database

    Well I switched over from Notepad++ to Netbeans to simplify the GUI processes. And of course by simplify I mean almost eliminate. In any case now that the basic underlying information needs have been identified and I have a GUI, the next step is an appropriate database for said information. However I am having some issues creating and connecting to the Derby database.
    I have already gone to Tools > Libraries > New Library, "JavaDBEmbedded" with the following classpath and Javadoc. All is good so far.
    C:\Sun\sdk\javadb\lib\derby.jar
    C:\Sun\sdk\javadb\javadocI used the following statement(s) to load the driver. I tried this both within the class and a method for a button. Within the method the first try is fine, however I am still getting an error for the second try.
    private void jButtonCreateActionPerformed(java.awt.event.ActionEvent evt) {                                             
    //Create the database below
    //Load the following driver
    try {Class.forName("org.apache.derby.jdbc.EmbeddedDriver");}
    catch (Exception driver) {}
    try {Connection dbConnection = DriverManager.getConnection("jdbc:derby:Map1;create=true", "Username", "Password");}
    catch (ClassNotFoundException ex) {ex.printStackTrace();}
    //Create the database above
    }Driver Manager doesnt strike me as a variable. Which is saying to me its trying to set one variable equal to another. Which means there is a problem creating a new instance of the "Connection" class?? Is there something I need to import to use the connection class?
    Cannot find symbol
    Symbol: Class Connection
    Location: jPanelMain
    Cannot find symbol
    Symbol:variable DriverManager

Which means there is a problem creating a new instance of the "Connection" class?? Is there something I need to import to use the connection class?Driver Manager isn't a variable. It's a class that provides a static factory method called getConnection that returns a java.sql.Connection for some given parameters. You can find more information about the Driver Manager class (and the getConnection() methods in particular) here. You need to import java.sql.DriverManager and java.sql.Connection.

  • How can i connect to remote database from netbeans

    Hi,
    I have got MySQL database server installed and running on a different machine. Is there any way to connect and browse database remotely using netbeans 5.5?
    I have added connector/driver for that database. i can connect and browse the database with host: "localhost" and port number. But when i specified the ip address of that machine, it gives me error.
    Can anyone help please.
    cheers.

    well, its not working in App server either.
    In App server admin console, on that connection pool if i define servername as "localhost", it works fine. If i change it to the remote machine's ip address, then it doesn't work.
    Any idea will be appreciated.
    cheers.

  • Problems with connection with Oracle Database (Dreamweaver)

    I'm trying to create a connection with a oracle database, with JDBC.
    In order to do that, I've downloaded the classes12.zip driver in my machine. This is the driver from Oracle.
    I've put this file into directory c:\Program Files\Macromedia\Dreamweaver MX\Configuration\JDBCDrivers.
    So, I've gone to Window -> Application -> Databases menu into Dreamweaver MX, clicked in the plus (+) signal and choosed Oracle thin Driver (Oracle).
    I've filled thin window with the following values:
    Connection name: conn1
    Driver: oracle.jdbc.driver.OracleDriver
    URL: jdbc:oracle:thin:@machinename:1521:SID
    Username: ....
    Password: ...
    When I click in the Test button into this window, the following success message appears:
    Connection was made successfully!
    But when I go to Bindings window to build a Recordset, the connection doesn't get the tables, and the following error message appears:
    Unable to retrieve tables from this connection, click on 'Define...' button to test this connection.
    Does somebody know the answer for this problem?
    Thank you.

    Don't bother with a loopback adapter unless you are using a laptop that needs Oracle to work whether connected or unconnected to the business network. Much simpler to just arrange for DHCP to assign you a fixed IP address (a lease reservation).
    It's the change of IP address which trips Oracle up, not the existence of DHCP. So if you can make sure your IP address will be the same, no matter how you acquire it, that's all you have to do.
    Installing a loopback adapter which isn't the primary interface at the point you install Oracle will mean your installation will get very confused as to whether to address things via the 127... address or the "normal" IP address. And yes, at that point, you'll not be able to connect to instances, or run listeners or do all sorts of other things reliably.
    If it were me, I'd uninstall the mess you probably now have as far as Oracle goes, install something like VirtualBox (free) or VMware Workstation (costs) and enjoy your Oracle experience inside the confines of a virtual machine whose networking setup you can configure and control to your heart's content, without it screwing up your real machine's ability to connect to your work's network when it needs to.

  • Problem in connection to the database

    Hi friends,
    I'm new in this forum and also Oracle.
    I installed Oracle 9i. Then I installed Oracle Suite 9i.
    When I was installing Oracle suite, at the and, it asked me Hostname in directory usage configuration, I tried different things like "localhost", mycomputer name and so on but it didn't accept. Now when I open oracle form and I want to connect to database, it doesn't accept and exit from Oracle form.
    Please write to me how I can solve this problem
    Thanks

    please post Forms related questions in the Forms discussion forum: http://forums.oracle.com/forums/index.jsp?cat=19
    Did you configure SQLNET?
    What error number did you get?
    Try looking up the error number in the Oracle documentation on OTN.

    Thx in advance

    student-java wrote:
    it gives the errors HTTP status 404-Servlet action is not availableThis is unrelated to the datasource configuration.
    HTTP 404 is a "Page not found" error. The request URL is simply wrong. Either there's a typo in the URL, or there is a typo in the servlet mapping, or the servlet is not there where you think.

  • Urgent: Problems with connecting to a database

    I have problems with getting a connection to both Oracle and Access.
    For Access I added the .jar files in my classpath.
    For Oracle I don't know which files I should add to the classpath.
    Here's the code:
    To connect with Access:
    public class AccessDatabase extends JFrame {
         private Connection conn;
         private Statement stmt;
         public AccessDatabase() throws SQLException,IOException{          
         DriverManager.registerDriver(new easysoft.sql.jobDriver());
         System.out.println("Connecting...");
    conn= DriverManager.getConnection ("jdbc:odbc:easysoft:db1");
         System.out.println("Connected");          
              stmt=conn.createStatement();
         ResultSet r=stmt.executeQuery("select name,adress from Tabel1");
         while(r.next()){
              String a=r.getString("name");
              String b=r.getString("adress");
              System.out.println(a+""+b);
    and for Oracle:
    public class AccessDatabase extends JFrame {
    private Connection conn;
    private Statement stmt;
    public AccessDatabase() throws SQLException,IOException{          
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    System.out.println("Connecting...");
    conn= DriverManager.getConnection ("jdbc:odbc:easysoft:db1");
    System.out.println("Connected");          
    stmt=conn.createStatement();
    ResultSet r=stmt.executeQuery("select name,adress from Tabel1");
    while(r.next()){
              String a=r.getString("name");
              String b=r.getString("adress");
              System.out.println(a+""+b);
         }}}     

    For getting connection from oracle you need to do 2 things.
    1-- As said earlier put classes12.zip in classpath
    2. For getting connection use as below ---
    instead of --conn= DriverManager.getConnection ("jdbc:odbc:easysoft:db1");
    Use thin driver ---
    conn = DriverManager.getConnection (jdbc:oracle:thin:@servername:portno , UserName,Password);
    replace servername UserName,Password in code you will get the connection.
    Thanks

  • Connect to Oracle Database Using Netbeans

    I am trying to connect to Oracle but it keeps saying that it is locked.
    ***Error:
    Cannot establish a connection to jdbc:oracle:thin:@localhost:1521:XE using oracle.jdbc.OracleDriver (ORA-28000: the account is locked )
    Just a FYI, this is the link that I am using to go through this program...
    https://netbeans.org/kb/docs/ide/oracle-db.html
    Any suggestions anyone??

    Ok, I uninstalled and reinstalled Oracle and it still wasn't working. However, it was an user issue. When I went back to the link that I previously posted and reread, it gave me the user name and the password that I was supposed to use, in order for this to work.
    username: systems
    password: whatever I used to set up Oracle.
    So, I didn't KISS - Keep It Simple Stupid.
    Thanks for trying to help.
    hope

  • Problem in connecting Non Oracle Database from Oracle

    Hi:
    I want to access "MS ACCESS" from Oracle 10g (10.2.0.1) using Windows XP.
    I tried my best, applied all proper instructions I found from books and from Internet, but getting an error.
    Here is what I did:
    My Oracle database is called "ORCL" and "MS ACCESS" is called "access_1".
    There is only one table "Employees" in "access_1".
    1. Accessed ODBC from Start | Control Panel | Administrative Tools.
    2. Clicked on Users DSN | "access_1" | Add.
    3. Clicked on "Drive do Microsoft Access (*.MDB)" .
    4. Hit Finish.
    5. Entered at DATA SOURCE NAME "ODBC1" and at DESCRIPTION "Connect Oracle to MS Access". Also I clicked on SELECT and chose the "Access_1.mdb" which is located at "C:\Documents and Settings\Muhammad\My Documents" folder. Clicked OK. and clicked on OK again.
    6. Now I went to Oracle side and configured listener as follows: (Only portion is shown here)
    # listener.ora Network Configuration File: C:\oracle\product\orcl\network\admin\listener.ora
    # Generated by Oracle configuration tools.
    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = C:\oracle\product\orcl)
    (PROGRAM = extproc)
    (SID_DESC =
    (SID_NAME = hsodbc)
    (ORACLE_HOME = C:\oracle\product\orcl)
    (PROGRAM = hsodbc)
    LISTENER =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (ADDRESS = (PROTOCOL = TCP)(HOST = RIYAZDESKTOP)(PORT = 1521))
    7. Configuring the hs file located at C:\oracle\Product\Orcl\hs|admin as follows:
    # HS init parameters
    # HS_FDS_CONNECT_INFO = <odbc data_source_name>
    # HS_FDS_TRACE_LEVEL = <trace_level>
    HS_FDS_CONNECT_INFO = odbc1
    HS_FDS_TRACE_LEVEL = OFF
    # Environment variables required for the non-Oracle system
    #set <envvar>=<value>
    8. The TNSNAMES.ORA File is located at C:\:\oracle\product\orcl\network\admin\ and has the following text (only the related text is shown here):
    # tnsnames.ora Network Configuration File: C:\oracle\product\orcl\network\admin\tnsnames.ora
    # Generated by Oracle configuration tools
    access_db.world =
    (DESCRIPTION =
    (Address = (PROTOCOL = TCP) (HOST = RIYAZDESKTOP) (PORT = 1521))
    (CONNECT_DATA = (SID = hsodbc))
    (HS=OK)
    9. The database link is created as follows:
    SQL> create database link access_db USING 'access_db.world';
    Database link created.
    SQL>
    10. Now the test and selection:
    SQL> select * from employees@access_db;
    select * from employees@access_db
    ERROR at line 1:
    ORA-28545: error diagnosed by Net8 when connecting to an agent
    Unable to retrieve text of NETWORK/NCR message 65535
