How to create a connection pooling in Netbeans 6.0 using the oracle driver

hi all,
I am using Netbeans 6.0. Apache Tomcat 6.0.14 server, oracle 9i.
I tried to create a connection pooling using tomcat web server.
I have included the following code in context.xml and web.xml.
CONTEXT.XML:
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/network1">
<Resource name="jdbc/myoracle"
auth="Container"
type="javax.sql.DataSource"
username="scott"
password="tiger"
factory="BasicDataSourceFactory"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:odbc:thin:@127.0.0.1:1521:mydb"
maxActive="20"
maxIdle="10"
maxwait="-1"/>
</Context>
WEB.XML:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<session-config>

<resource-ref>
<description>Oracle Datasource example</description>
<res-ref-name>jdbc/myoracle</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
After that i have included the following JDBC driver's jar files in the $Catalina_Home/lib folder.
classes 111.jar,
classes 111_g.jar
classes12.jar
classes 12_g.jar
classes12dms.jar
classes12dms_g.jar
nls_charset11.jar
nls_charset12.jar
ocrs12.jar
ojdbc14.jar
ojdbc14_g.jar
Then i stop the tomcat web server and start it again.
In jsp page i have included the following code:
Context ctx=new InitialContext();
Context envctx=(Context)ctx.lookup("java:comp:env");
DataSource ds=(DataSource)envctx.lookup("jdbc/myoracle");
Connection con=ds.getConnection(); ----->(In this line an error occured that Connection class cannot be found.)
please help me how to create a connection pooling and rectify the error in conneciton.
Thanks in advance

    How do I load windows 7 on a Mac Air using the super drive?

    You use Boot Camp to partition the SSD in the Air, download the Win 7 Support files from Apple (part of the boot camp process), save them to a USB thumb drive, have the USB superdrive connect to the Air with the Win 7 install DVD in the drive. Once partitioned the system will reboot and start the Win 7 install.

  • How to Create a connection pool in OSB java callout

    Dear Team,
    In our project, we need read some data from DB, and do corresponding operation. currently, we need setup the connection first, execute the SQL, and close the connection.
    But the concurrency of call is very high, is there a way to create a connection pool, then we can use the connection pool to get the connection and execute the SQL, then return the connection to the pool.
    if connection pool is not available, is there any way to create the connection outside the java callout, that we can just execute the SQL in java callout.
    The OSB version is 11.1.1.6.0
    Thanks.
    Best Regards,

    Hi Team,
    Thanks for your help.
    What I need is not only the db connection, may be other kind of things, such as read configuration from file...
    If I write the code in java callout with static java method to create and close the connection, each time when request come in, OSB will create a new connection (or read the file), I think it's not the best practice to do this kind of work.
    I think the weblogic is running in JVM, is there any way we can define variables or new object in the JVM directly?

    Is there any way to create a new file(text, doc, docx, ppt, pptx, xls or xlsx) using the the secondary click (on the desktop or any folder) just like creating a new folder using secondary click! Please do let me know!

    No. You need the Office applications to create them or another application capable of creating those types of files or at least saving files in those formats.

  • How to create datasource/connection pool programatically?

    Hello,
    We are developing a system that connects to multiple databases by dynamically switching datasources, using ADF 12.1.3. Application is deployed on weblogic and glassfish.
    There is no problem on switching and working on multiple datasources which is created previously on the application server (weblogic/glassfish).
    Now we need to create a datasource while system is running.
    Is it possible to create datasource programatically, and list datasource previously created?
    Jdeveloper/ADF: 12.1.3.
    Thanks,
    Ganbat Bayarbaatar.

    Dear Ashish,
    Thank you for your response, but that is not what I was looking for.
    I haven't any problem on changing datasources. I would like to create new datasource on application server.
    On Andrejus's post, there is a comment about what I'm asking:
    Syed : Nice Post. To enhace this more further. How can we get list of JDBC Data sources available in weblogic in the ADF Application.
    Andrejus: By using WebLogic API this should be possible or by accessing MBean...
    Is there any more-detailed blog post or doc, about "Weblogic API", "MBean"  and using them to create datasource?
    Thanks,
    Ganbat.

  • HOW DB POOLING WORK AND HOW TO CREATA A DB POOLING IN JSP

    HI! I'm new in programming JSP and in web programming. I would like to learn how does the DB pooling work and how to create a DB Pooling. THANKS....

    Thanks for the idea but i need a more detail one...
    Hi,
    Db connections are one of the most expensive
    operations in an application.So at applicatin launch
    only multiple connections to the dbase are opened and
    used and returned/closed after usage.
    You can have a loop running 10 times creating a
    connection every time and putting those in a
    Collection object (say hashtable) marked with a key.
    Then in the application code , take an available
    connection from the hashtable and use it . After use
    return /close the connection (your pool can be
    incremental..creating 5 connections evey 10-15

  • A question about creating a Connection pool that uses Oracle JDBC

    Dear all,
    I have an issue with creating a connection pool within a web application in order to be used by several servlets. I appreciate if you could kindly give me a hand.
    I'm using:
    Web server: Apache-tomcat: 6.0.18
    Oracle Database 11g Enterprise: 11.1.0.6.0 - Production
    Operating system: Linux (ubuntu 8.10)
    IDE: Sun Netbeans
    Oralce JDBC Drivers: 11.1.0.7.0-Production (ojdbc6.jar and orai18n.jar)
    JDK 1.6
    Usually, just for creating a connection to my database (without using a connection pool), I proceed in the following way:
    String dbURL = "jdbc:oracle:thin:@localhost:1521:database01";
    String username = "scott";
    String user_password = "tiger";
    String userSqlQuery = "SELECT * FROM mytable";
    Connection connection = DriverManager.getConnection (dbURL, username, user_password);
    Statement statement = connection.createStatement();
    statement.executeUpdate(query_text);This works pretty well allowing to communicate with my oracle database. By this method I have run several projects
    with different queries (SELECT, INSERT, UPDATE, DELETE ,etc.) and each time it worked without any problem and
    returned the result of the query. Therefore I think that there is no problem with JDBC drivers
    However, when I want to create a connection pool, it seems that the lookup method cannot locate Oracle JDBC drivers. That is,
    try
         InitialContext ic = new InitialContext();
         Context envContext  = (Context)ic.lookup("java:/comp/env");
         dataSource = (DataSource)envContext.lookup("jdbc/oracle11gEnterprise");
           Connection connection = dataSource.getConnection();
    catch (Exception e)
         e.printStackTrace();
    }Just after calling dataSource.getConnection() the java.lang.NullPointerException is thrown.
    Any idea?
    Thanks in advance,

    E. Davis,
    http://www.javaworld.com/javaworld/jw-06-1998/f_jw-06-object-pool.html,
    and used it to build an ldap implementation. How can I apply this to

  • Error in creating a connection pool (No suitable driver)

    I try to create a connection pool in a Weblogic server 7.0 with the following config:
    URL:
    jdbc:oracle:oci9:@db_name
    Driver Classname:
    oracle.jdbc.driver.OracleDriver
    Properties(key=value):
    user=user_name
    password=user_password
    dll=ocijdbc9
    server=db_name
    protocol=oci
    my computer (windows 2000) has installed Oracle 9i client, and this connection
    pool will connect to Oracle 8i server. Besides, I have config classes12.zip in
    the "classpath" and ocijdbc9.dll in the "path" environment variables.
    Can Oracle 9i driver connect to a Oracle 8i server? Or there is other problems?
    Thanks in advance.

    Please try URL = jdbc:oracle:oci8:@db_name... that should be fine.
    Yes, you can connect to 8i oracle database using 9i driver.
    Also, make sure you have classes12.zip in classpath and ocijdbc9.dll in path.
    Thanks,
