About jdbc and axis

hello..!
I want to learn webservices using java and MySql. can anybody tell me how can I set up jdbc connection in my w/s? I am using tomcat and axis.
Thank you.
.Mohit

Axis and JDBC aren't really related technologies. Learn how to write a JDBC program. Learn how to write an Axis program. Er... that's it.

  • A very surprise problem about JDBC and connection pool

    I occur a very problem about JDBC and connection pool on Weblogic Platform
    8.1.
    There is a table in Oracle
    Table
    Name: t1
    id varchar2(5);
    content clob;
    id is primary key.
    If I use a connection pool to connect to Oracle,like following program:
    InitialContext ic = new InitialContext();
    DataSource ds = (DataSource) ic.lookup("cgOracleDataSource");
    con = ds.getConnection();
    then following program will throw a ClassCastException
    String sql = "select content from t1 where id = ?";
    PreparedStatement pst = con.prepareStatement(sql);
    pst.setString(1,"001");
    oracle.sql.CLOB clob = (oralce.sql.CLOB)rs.getClob("content") //this
    statement will throw ClassCastException
    but if I use JNDI to connect to Oracle,like following program, then those
    program above is ok
    private String dbdriver="oracle.jdbc.driver.OracleDriver";
    private String dburl="jdbc:oracle:thin:@192.168.7.148:1521:ep";
    private String username="ep";
    private String password="epuser";
    Class.forName(dbdriver);
    conn = DriverManager.getConnection(dburl, username, password);
    conn.setAutoCommit(false);
    On the contrary, if I use JNDI to connect to Oracle, following program will
    throw ClassCastException
    weblogic.jdbc.vendor.oracle.OracleThinClob clob =
    (weblogic.jdbc.vendor.oracle.OracleThinClob)rs.getClob("content");
    but it is fine if I use connection pool to connect to Oracle.
    I am confused this problem, who can tell me why?

    When you are getting connection using datasource lookup from weblogic
    connection pool, this connection is internally wrapped and hence you have to
    cast it to weblogic.jdbc.vendor.oracle.OracleThinClob which you do and so it
    works.
    But when you get connection by loading driver straight, you are getting naked
    oracle connection. In this case when you cast it to oracle.sql.Clob it works,
    as you have seen in your test case.
    I hope this explains what is going on with your code.
    Thanks,

    Hi Graham
    I'm making a bit of progress. I found a website that suggested the following
    This is a problem of the used sockets with Windows NT. You can request the active sockets with the command netstat. The problem is a function of:
    MaxUserPort (default 5000)
    KeepAliveTime (default 120)
    it suggested the workaround was connection pooling
    I have run netstat to look at the number of connections when the problem occurs and waited for the timeout to reset the os back to the minimum and on each occasion my report has run
    Does this sound logical?
    If so
    do you have any examples on connection pooling
    it seems that even if i have closed my database connection it still doesn't free my port that was used, that's why i get this error
    i am looking for a way to close my db connection and free its socket or port used at the same time, hope you can help,
    thanks in advance

  • A question about JDBC and MySQL

    hello dear friends,ask a question:
    if in MySQL database, i have defined a clumon as TEXT data type.
    when i use JDBC, i use which kind of java data type to hold TEXT,
    i mean which getXXX() method i should use.
    is it possible i just use getObject() and cast it to a binarystream??
    thanks in advanced.

    use this:
    declare it 1st
    String x ="";
    then u can now get the value of the field...
    x = getString("<fieldName>");is there length limitation?
    for example, i want store a String which is got from a JTextArea, i also treat it as String and insert into the column with TEXT datatype like
    insert table_name (text_column) values( string_1)
    this works in JSP, should work in JAVA too...
    hope i helped... ^_^

  • About JDBC and JNDI

  • Question about JDBC and Oracle 10g AL32UTF8

    Hey all,
    Currently I have a Java program that uses lib: ojdbc14.zip. It works fine for our Oracle 10g database, but when we converted our character set to AL32UTF8, our program seems to have stopped working properly. For instance, I grab a count(*), to see how many rows an ID has in a table. Then I take that list and display and count(*) that are greater than 0. Well, my first getString works properly to generate the select count(*) statements for all the tables in the database. But then when I execute those select count(*) I can grab out the number greater than 0. That's column 1. Then the owner name is displayed in column 2. and the table name is displayed in column 3. When I do a getString(2) we only get the first letter (sometimes) of the owner of the table. Same with the table name.
    For instance, before AL32UTF8
    getString(2): SCOTT
    getString(3): PEOPLE
    After
    getString(2): S
    getString(3): P
    Now to open my connection I use:
    static Connection conn;
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    conn = DriverManager.getConnection(connection_string, username, password);
    And to create query I use:
    Statement query_1 = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
    Any help will be greatly appreciated. Thanks
    Sincerely,
    Mel

  • Which tutorials may you suggest for JDBC and servlets?

    Hello, i would to learn about JDBC and servlets.
    May you please suggest me a good tutorial(e.g.post me a link) in order to study for JDBC and servlets?
    e.g. How to make a servlet etc.
    Thanks, in advance!

    I agree with PhHein, it's best to learn one technology and then the other. (Just my two cents, but start with JDBC from a simple standalone application, then when that is working, try to tackle Servlets, since you will need to also learn how to get them working in a container like Tomcat).
    Here is a tutorial that has both concepts in it at the same time. Site is down now, but is usually up. http://www.roseindia.net/jdbc/jdbcconnectivity.shtml
    Also, you will eventually want to download a J2EE container such as Tomcat or Jboss.

  • JDBC and FTP sender channels stop polling

    Hi,
    We have a great volume of sender JDBC and FTP sender channels.
    For this reason there is nothing unusual to have temporary error connections.
    Several months ago, with an XI 3.0 system, sender channels recover its functionality  automatically when temporary error connection is solved.
    But now, he have migrate to a  PI 7.1 sytem, and in the same scenario and configuration,  sender channel stop polling after a temporary error . In cc monitor this channels remains in  green status and there were no signs of stopped interfaces.
    Timeouts are correctly defined and there is no difference between channel configuration in our Xi and PI system.
    How to solve this problem?
    Thanks, in advance.

  • Adapter Limitations Of Sender  JDBC and Mail Adapter

    hi All,
    could you tell me the limitations of JDBC and Mail Adapter .i need to document these details .
    Regards
    Vidya Sagar

    HI Vidya,
    If i was you, i would do a list of things that i would need about these adapters, o i would search the SAP.help documentation for a first view and later ask about this possibility. Another way is to read the SCN doubts about these adapters and you can find some problems. You should think about the PI version as well.

  • JDBC and Linguistic Sorting

    The problem: oracle jdbc thin driver doesn't see environment variable NLS_SORT
    Description:
    We have a lot of code written in coldfusion and now we would like to switch form CF5 to CFMX. We use oracle thin driver to connect CFMX to oracle DB.
    The problem is that "order by" doesn't work as earlier. It seems that it jdbc driver couldn't make linguistic sorting, only binary. I tried with different versions, classes12.jar and ojdbc14.jar (the newest from otn).
    I know that i could solve problem if use sql function nlssort but it is not acceptable for us. We couldn't change all our source code. We would like to use env variable NLS_SORT to control this behaviour.
    I also wrote small standalone java program to test this directly but it doesn't see NLS_SORT. sqlplus from same shell works well.
    Is it possible to set oracle jdbc thin driver to use NLS env settings (NLS_SORT)?
    If yes, how? If not, what is the way to do linguistic sorting using jdbc?
    Thank you,
    Zeljko

    Zeljko,
    I don't have an answer for you (sorry), but I can suggest some resources where you may find the answer (hopefully -- assuming you haven't already tried them).
    The section entitled JDBC and Globalization Support in chapter 18 ("Advanced Topics") of the "Oracle9i JDBC Developer's Guide and Reference, Release 2 (9.2)".
    [Note: Since I couldn't see any details in your post about which Oracle version you are using, I assumed it was 9.2. However, you can access Oracle documentation for all the latest versions from the [url=http://tahiti.oracle.com]Tahiti Web site.]
    The Globalization Development Kit may be helpful.

  • How to use JMS with tomcat and Axis

    Hello
    I'm new in ii, so i'm still a little bit lost. I have been implementing web services with tomcat and Axis. However, these services are synchronous and I would like that some services were asynchronous.
    I've been reading about the topic and I've found that JMS is a good solution for it. I have already downloaded JMS in my computer but now I don't know what else to do. I've been trying to run the SimpleQueueSender.java example but I get the error:
    JNDI API lookup failed: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
    But I have attached all .jar from F:\Sun\MessageQueue\lib
    In addition to this, for my first webservices I used the Java2WSDL, WSDL2Java and AdminClient (axis tool) to create my web services bindings, stubs and skeletons and to deploy the web service on the server. Do I have to use them now with JMS? or now the deployment must be performed in a different way?
    Thank you in advanced,

    The error means that you have to specify the type and location of your jndi store. You could create a jndi.properties file and put two properties in it:
    java.naming.provider.url=file\\\:////var/jndi
    java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory
    for a file based jndi store. Then you have to make sure your jndi.properties file is in your CLASSPATH. Then you have to use something like imqadmin to create your jndi store and store in it your administrative objects like Queues and QueueConnectionFactories.

  • JDBC and ABAP proxy

    Hello guys , need help with the following scenario :
    ZTable as sender through Xi to db. i have never worked on this type before . Need some help in any blogs or scenarios dealing with the same . Interfacing ztable through a abap proxy.
    I am also confused on the concept of client and server proxy . Please suggest
    Krishnah

    Hi Krishna,
    <u><b>
    CLIENT PROXY:</b></u>
    A WSDL description from a UDDI server (or an Internet page) is usually used to make a service executable in the Internet and to describe the interface of this service. You require a client proxy and not a server proxy to call this service by using the Web service infrastructure.
    <u><b>SERVER PROXY:</b></u>
    You can only generate ABAP server proxies from a WSDL description if they originate in the Integration Repository.You can also generate server proxies for Java and client proxies for ABAP from message interfaces.

  • ####a question about jdbc driver

    A question about jdbc driver: for Oracle JDBC drivers which will not allow O/R
    tools to access columns over 4 kb. This affects some of the functionality of my
    application.A workaround is to use the my JDBC driver that acts as a wrapper to
    ensure that columns over 4 kb read and persist properly. my JDBC driver determines
    which actual driver to load based on the connection URL. If you pass in a URL
    that contains the string jdbc:oracle:thin, it will know to load oracle.jdbc.driver.OracleDriver.
    If the URL contains the string jdbc:db2, it will know to load COM.ibm.db2.jdbc.net.DB2Driver,
    and so on.
    now i have set CLASSPATH for my jdbc wapper,when I Creating and Configuring a
    JDBC Connection Pool,i have to input my driver name such com.lawrence.driver.....then
    i did,all
    is well,then i restart my WLS,when load config.xml,some errors such as "No registered
    driver accept URL:jdbc:oracle:thin:@localhost:1521:lawrence",if i set driver name
    is oracle.jdbc.driver.OracleDriver,all is good,no any errors.
    I find some questions like:
    1.for WLS8.1 ,it is only find some registed driver?
    2.why it cannot load my driver wapper when it is loading jdbc Connection Pool,but
    when the WLS start is finished, i Creating and Configuring a JDBC Connection Pool
    then it is right?

    my JDBC driver like this:
    public class myDriver implements Driver {
         public static String DB2_DRIVER = "COM.ibm.db2.jdbc.net.DB2Driver";
         public static String DB2_URL = "jdbc:db2:";
         public static String HYPERSONIC_DRIVER = "org.hsqldb.jdbcDriver";
         public static String HYPERSONIC_URL = "jdbc:hsqldb:";
         public static String MYSQL_DRIVER = "com.mysql.jdbc.Driver";
         public static String MYSQL_URL = "jdbc:mysql:";
         public static String ORACLE_DRIVER = "oracle.jdbc.driver.OracleDriver";
         public static String ORACLE_URL = "jdbc:oracle:";
         public static String POSTGRESQL_DRIVER = "org.postgresql.Driver";
         public static String POSTGRESQL_URL = "jdbc:postgresql:";
         public static String SQLSERVER_DRIVER =
              "com.microsoft.jdbc.sqlserver.SQLServerDriver";
         public static String SQLSERVER_URL = "jdbc:microsoft:";
         public boolean acceptsURL(String url) throws SQLException {
              return true;
         public synchronized Connection connect(String url, Properties props)
              throws SQLException {
              if (_driver == null) {
                   Class driverClass = null;
                   try {
                        if (url.startsWith(DB2_URL)) {
                             driverClass = Class.forName(DB2_DRIVER);
                        else if (url.startsWith(HYPERSONIC_URL)) {
                             driverClass = Class.forName(HYPERSONIC_DRIVER);
                        else if (url.startsWith(MYSQL_URL)) {
                             driverClass = Class.forName(MYSQL_DRIVER);
                        else if (url.startsWith(ORACLE_URL)) {
                             driverClass = Class.forName(ORACLE_DRIVER);
                        else if (url.startsWith(POSTGRESQL_URL)) {
                             driverClass = Class.forName(POSTGRESQL_DRIVER);
                        else if (url.startsWith(SQLSERVER_URL)) {
                             driverClass = Class.forName(SQLSERVER_DRIVER);
                        _driver = (Driver)driverClass.newInstance();
                   catch (Exception e) {
                        throw new SQLException(e.getMessage());
              Connection con = _driver.connect(url, props);
              return new myConnection(con);
         public int getMajorVersion() {
              return _driver.getMajorVersion();
         public int getMinorVersion() {
              return _driver.getMinorVersion();
         public DriverPropertyInfo[] getPropertyInfo(String url, Properties props)
              throws SQLException {
              return _driver.getPropertyInfo(url, props);
         public boolean jdbcCompliant() {
              return _driver.jdbcCompliant();
         private Driver _driver;
