Am trying to connect to database using thin driver am getting an error.may i know the exact problem. If any one provide the solution in steps wise better.The following is the error.
Exception in thread "main" java.lang.ClassNotFoundException: oracle.jdbc.oracledriverThe JAR file is not in your classpath. Depends on what JAR you are using (ojdbc14.jar, ojdbc5.jar, etc). Bottom line, it can't find the class for the driver due to the JAR not being in the classpath.

    looks like you didnt complete the install of the instant client. the ORACLE_HOME and TNS_ADMIN points to the location of the tnsnames if you dont have the full tns string in your jdbc connection string

  • Getting exception while trying to connect mysql database

    hi
    i am using mysql as database while connecting to database using jsp i am getting the following exception
    "java.lang.ClassNotFoundException:com.mysql.jdbc.Dr iver"
    can any one tell wha tis the actual problem
    regards

    If you've tens of applications on the server which
    makes use of the same driver/JAR, then you can put
    this JAR in the classpath of the server to save
    WAR/EAR space. And about differing versions: I am not
    used to do so. Otherwise just put the different/older
    version in the classpath of the webapp and then give
    it higher priority in the classloader.If you are using Enterprise Applications, disk space for the code should be your last concern. If you don't have enough of that for each of the applications to have their own space for the third party jars that they use, then you need a new server, as the one you have is not going to be able to handle the load anyway.
    And as far as fiddling around with the classpath to avoid jarfile "collision" or incapability, good luck. The first time you add a new application all the others will stop working and you will have to spend two days reordering the classpath properly, so that they all work again. I know, because I have seen it happen, even though I suggested to them to do it the other way, they insisted on doing things the way you suggested and, like I said, as soon as they added the next application, the server was down for two days, until they got all of the classpath/(classloader priority) issues straightened out.

  • Not able to connect to database using toad

    we have a 11.1.0.7 database on solaris machine.
    when the development team tries to connect to it using toad, it gives them ORA-01017: invalid username/password error.
    We are using TNS entries to connect. From the same client machine, we are able to connect using SQLPLUS and SQL Developer using the same TNS entry. However, its not working on TOAD.
    Toad Version is 9.0.1. Any help is much appreciated.
    Thanks.

    Hi Muneer,
    My answer is arriving to this forum late, but I'll tell you what is happening to benefit others who have this issue. Older versions of Toad convert the case of the password to upper case when they attempt to authenticate to Oracle. Versions of Oracle prior to 11G had case insensitive passwords so it did not matter. But when 11G came out with it's case sensitive passwords, Toad could no longer authenticate. You can test this yourself by modifying the password for your Oracle account (usnig sqlplus) so that the password is completely upper case.....Toad will suddenly be able to authenticate.
    You will find that sqlplus and SQL Developer don't have a problem. That is because they don't convert the password to upper case, they just leave it as it is. I don't know why older versions of Toad convert the password to upper case, but that is what they do. Newer versions of Toad fix the issue. I believe that Toad versions 9.5 and later should work. I've also read, however, that 9.5 had issues with Oracle 11G client libraries so you might just want to upgrade to the latest/greatest version of Toad.

  • Ora-12154 when trying to connect to database from fortran application

    I am trying to connect to database and run an simple select query to a table(without any where clause) using pro*fortran code.

    Hi Nitin
    Thanks for the helpful! With your point I'm now Pro! Great thanks.
    By the way have your seen that?
    Files such as LISTENER.ORA, TNSNAMES.ORA, SQLNET.ORA, if configured manually, or copied and edited from earlier releases of Oracle Database may have record attributes that are incompatible with Oracle Database 10g release 2. The software cannot read such files. The required record format is stream_lf and the record attributes are carriage_control and carriage_return.
    This may result in:
    Inability to start the listener
    Services not registered with the listener
    Inability to connect to other databases
    ORA-12154: TNS:could not resolve service name
    Run the following command on each file affected:
    $ DIR/FULL filename
    An output similar to the following may be displayed:
    Record format: Variable length, maximum 255 bytes
    Record attributes: Carriage return carriage control
    If the output includes the preceding entries, then run the following command:
    $ CONVERT/FDL=SYS$INPUT filename filename
    RECORD
    CARRIAGE_CONTROL CARRIAGE_RETURN
    FORMAT STREAM_LF
    ^Z
    Otherwise herewith an interesting metalink note. Doc ID:      Note:437597.1

  • Not able to connect to database using jdbc

    Respected sir/madam,
    I am new to java and i am trying to connect to database which is necessary for me in project when i wrote the code using class.forName i am able to compile but when runnig i am getting two exceptionns one is oracle.jdbc.driver.oracledriver not found or excetion in thread main class not found please help me

    Subash,
    1) Please refrain from cross-posting (posting the same message into two or more forums). This question was better asked in the JDBC forum as you eventually put it but you already posted here so if that happens again next time just leave the original thread be.
    2) Your compilation classpath and your runtime classpath are not related. As a matter of fact with well written JDBC code and under most conditions you should not need your driver in your compilation classpath at all, only your runtime one.
    3) Your driver is not in your runtime classpath. That is the error that you need to resolve.

  • Connecting with database using setproperty over SOAP connection

    The following method connects to a MySQL database.
    public void setDBDriverName(String in)
         dbDriverName = in;
    public void setDBConnection(String in)
         dbConnection = in;
    public void connectToMySQLDatabase() throws SQLException
         if(dbCon == null)
                 try
                    Class.forName(dbDriverName);     // SQL driver
                    dbCon = DriverManager.getConnection(dbConnection);           // JDBC url
                    s = dbCon.createStatement();
                       catch (Exception e)
                    System.out.println("Could not connect to database using " + dbConnection + " at " + dbDriverName + " : " + e.getMessage());
         else
                System.out.println("Could not connect to databse : Already connected");
    }The method is part of a webservice, in which I use setproperties to set the database connection because the webservice must work with different types of databases like Oracle and MySQL.
    <jsp:useBean id="ContactHistorieClassid" scope="request" class="proxy.soap.ContactHistorieClassProxy" />
         <jsp:setProperty name="ContactHistorieClassid" property="DBConnection" value="org.gjt.mm.mysql.Driver" />
         <jsp:setProperty name="ContactHistorieClassid" property="DBDriverName" value="jdbc:mysql://localhost/contacthistorie" />
         <jsp:setProperty name="ContactHistorieClassid" property="clientID" value="1" />
    <%
         ContactHistorieClassid.connectToMySQLDatabase();
    %>What am I doing wrong here?

    Forgot what happens, sorry. After trying to use the ContactHistorieClassid.connectToMySQLDatabase() method, my server console tells me that it cannot connect to the database, even though it returns the values as they were set in the setproperty.
    When I manually enter the values like this...
    Class.forName("org.gjt.mm.mysql.Driver");     // SQL driver                
    dbCon = DriverManager.getConnection("jdbc:mysql://localhost/contacthistorie"); .. it works properly. So the setproperties are executed as the should be.

  • Packet received fails when trying to connect to database

    Dear experts,
    i always received an error message: Packet Received Failed whenever i tried to connect to my 9i database. Once a while i will b able to connect without problem but sometimes is very annoying that i keep receiving this error and i have to retries a lot of time to connect depending on my luck.
    Does anyone have any idea what could be wrong here?
    Many thanks in advance for your advise.

  • How to connect to database using sqlplusW (windows based  sqlPlus)

    Hi
    Thank you for reading my post
    I did some search and i find that i should use some kind of SYSTEM/SYSTEM@ORCLE
    to connect to database using windows based sqlplus.
    in the above SYSTEM is username and password and ORCLE is SID.
    but sqlplusw says that
    could not resolve the connect identifier specified.
    where i can find complete information about HOST string ?
    thanks

    You can look inside yours tnsnames.ora file it can be found in %ORACLE_HOME%\network\admin
    MOB92 =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = xxx)(PORT = 1521))
    (CONNECT_DATA =
    (SERVICE_NAME = MOB92.world)
    Here my network service name in MOB92 so in sqlplus I would use:
    system
    password
    mob92
    and it should work. If you have no such entry in tnsnames.ora file you can use for example Network Configuration Assistant to configure your network service name.
