Problems with Oracle 9i and Tomcat

Hello,
I am running Tomcat and Oracle 9i. I am trying to get my connection pooling working so I can use a JNDI. But I am having a problem.
When I include everything in a jsp file it connects to the database and produces a result.
Connection conn = null;
try
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection(
"jdbcracle:thin:@xxx.xxx.xx.xx:1521:dev",
"happy",
"xxxx");
When I have it in the Context I just get:
A Java.nullpointerexception
My server.xml is:
<parameter>
<name>url</name>
<value>jdbcracle:thin:@xxx.xxx.xxx.xxx:1521:dev</value>
</parameter>
With the same parameters for username and password as above.
My servlet is:
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception("Oops - No Context");
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/database");
if (ds != null)
conn = ds.getConnection();
All your help is appreciated:

Try out the new driver by Oracle ojdbc14.zip or ojdbc.jar

  • Some problems with servlet.jar and tomcat 4.1.27

    Hello everybody,
    I used to work with tomcat 3.3.1 and i've decided to use tomcat 4.1.27 now. The manual explains that we have to change de version of servlet.jar, it's done with servlet-2.3.jar but on tomcat starting i have this message:
    jar not loaded. See servlet spec [...]. Offending class: javax/servlet/Servlet.class
    what can i do, i've red all de documentation and i think all versions a OK??
    thanks per advance
    antoine

    I am running Tomcat 4.1.18, so your configuration may be slightly different. I found the Servlet.class file you are missing residing in the Tomcat/common/lib directory in the Servlet.jar file. Check your path and also make sure your Servlet.jar file contains the missing class.

  • I have a problem with JDBC Realm in Tomcat/Oracle/Win XP

    I have a problem with JDBC Realm in Tomcat.
    I have attached my server.xml file located in the
    C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\server.xml
    The Problem is that when I login I get the user name and password prompt but it does not resolve.
    When I enter in the tomcat-users.xml password with memory realm uncommented it works fine.
    C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\tomcat-users.xml
    Is there a cache or something I need to reset for the JDBC Realm to work?
    I have attached my tables and contents as well...
    Did I miss something????
    Thanks

  • Oracle 9i, Rel.2 - Problems with dynam statement and cursor

    Hello,
    I have the following problem with Oracle 9i, Release 2:
    I have a SQL-statement, which I create with the help of a configuration table. That means I don’t know how this statement looks at runtime. It could be look like this:
    SELECT Att1, Att2, Att3
    FROM Tab1
    or this…
    SELECT Att1, Att2
    FROM Tab1
    or this…
    SELECT Att1
    FROM Tab1
    etc.
    That means I don’t know in advance how many columns will be in the select-clause.
    Here my code snippet until here:
    v_query_str := 'SELECT ' || v_select_clause_str
    || ' FROM cb.' || v_table;
    ,,v_select_clause_str" willl be created dynamically
    ,,v_table" is as well from the config-table
    Now I want to iterate through the result of the query and do further processing.
    For this reason I wanted to use a cursor, iterate through the rows and save every value of each row in an own variable (but I don’t know the number of columns!!!).
    But how can I open a cursor and iterate through it without knowing the number of columns???
    The following code is NOT working:
    TYPE t_dataColumnComp IS TABLE OF VARCHAR2(200);
    a_dataColumnComp t_dataColumnComp;
    --here I create the query…
    v_query_str := 'SELECT ' || v_select_clause_str
    || ' FROM cb.' || v_table;
    OPEN c_tempAtt FOR v_query_str;
    LOOP
    FETCH c_tempAtt INTO a_dataColumnComp; --THIS DON’T WORK
    EXIT WHEN c_tempAtt%NOTFOUND;
    FOR i IN 1..a_dataColumnComp.COUNT
    LOOP
    DBMS_OUTPUT.PUT_LINE(a_dataColumnComp(i));
    END LOOP;
    END LOOP;
    CLOSE c_tempAtt; --close cursor variable
    Regards
    Homer

    You will need to use DBMS_SQL to handle this since the number of columns in the result set is not known until runtime.
    See here for an example of using DBMS_SQL:

    Hey Kanwal,
    You can try the following statement
    UPDATE TABLE_NAME SET DATE_COLUMN = to_date('08/16/2000 12:45:00','mm/dd/yyyy HH:MI:SS'
    WHERE .... ;

  • Performance problem with Oracle

    We are currently getting a system developed in Unix/Weblogic/Tomcat/Oracle environment. We have developed a screen that contains 5 or 6 different parameters to select from. We could select multiple parameters in each of these selections. The idea behind the subsequent screens is to attach information to already existing data/ possible future data that matches the selection criteria.
    Based on these selections, existing data located within the system in a table is searched and those that match are selected. Also new rows are created in the table against combinations that do not currently have a match. Frequently multiple parameters are selected, and 2000 different combinations need to be searched in the table. Of these selections, only about 100 or 200 combinations will be available in existing data. So the system is having to insert 1800 rows. The user meanwhile waits for the system to come up with data based on their selections. The user is not willing to wait more than 30 seconds to get to the next screen. In the above mentioned scenario, the system takes more than an hour to insert the new records and bring the information up. We need suggestions to see if the performance can be improved this drastically. If not what are the alternatives? Thanks

    The #1 cause for performance problems with Oracle is not using it correctly.
    I find it hard to believe that with the small data volumes mentioned, that you can have perfornance problems.
    You need to perform a sanity check. Are you using Oracle correctly? Do you know what bind variables are? Are you using indexes correctly? Are you using PL/SQL correctly? Is the instance setup correctly? What about storage, are you using SAME (RAID10) or something else? Etc.
    Facts. Oracle peforms exceptionally well. Oracle exceptionally well.
    Simple example from a benchmark I did on this exact same subject. App-tier developers not understanding and not using Oracle correctly. Incorrect usage of Oracle doing a 100,000 SQL statements. 24+ minutes elapsed time. Doing those exact same 100,000 SQL statement correctly (using bind variables) - 8 seconds elapsed time. (benchmark using Oracle 10.1.0.3 on a Sunfire V20z server)
    But then you need to use Oracle correctly. Are you familiar with the Oracle Concepts Guide? Have you read the Oracle Application Developer Fundamentals Guide?

  • Problem with Oracle 11g(32 bit) installation on windows 7 ultimate edition

    Hello all,
    I have a problem with Oracle 11g(32 bit) installation on windows 7 ultimate edition (32 bit).
    I have successfully installed it immediately after OS installation. But today, i have decided to deinstall it and go for Oracle 10g version for 32 bit.
    Everything went normal during installation, but i can see the services is not present in services.msc. Also its throwing some exception for dbca, netca
    Now i tried to deinstall it and again go for 11g. But even the same story here..
    Can anybody give me a solution for this..
    -Regards
    Rajesh Menon

    ur problem is that u install latest version and now u trying to installing old version.
    now u need to uninstall 10g and delete oracle from services, if the probleme presist then u should
    install fresh windows 7.
    Regards
    SaqibNo need to install a fresh OS. That's like tearing your house down just because you wired a lamp wrong and blew a circuit breaker.
    There are MeaLink notes on how to eradicate an Oracle install from Windows, but it boils down to this:
    Stop all Oracle services
    In the registery:
    - Delete all oracle services from the register (HKLM\SYSTEM\CurrentControlSet
    - Delete the entire Oralce folder from HKLM\Software
    reboot
    Delete the ORACLE_HOME directory and any other Oracle related directories/files. Offhand, it seems like there is an Oracle directory under Program Files.
    reboot

  • A lot of problems with Oracle BI SEE 11g

    I have a lot of problems with Oracle BI SEE 11g
    1. I upgraded my BI SEE 10 repository and can it openning in offline mode.
    2. I can't deploy my upgraded repository in EM MW Control 11g - when i try to open Farm_bifoundation_domain->Business Intelligence->coreapplication, i get error "Stream closed
    For more information, please see the server's error log for an entry beggining with: Server Exception during PPR, #41".
    Opening Logs by EM control doesn't work too.
    in file middleware\user_projects\domains\bifoundation_domain\servers\AdminServer\logs\AdminServer.log i see this event:

    Have you any ideas?
    3. Ok, i taking sample repository and adding a new datasource in it:
    Database: Oracle 8i
    Connection pool:
    Call interface OCI 8i/9i
    Data source name:
    (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (Host = oraapp) (Port = 1521) ) ) (CONNECT_DATA = (SID = MYSID) ) )
    This settings are working fine in BI 10.
    In BI 11g i get this funny error: "The connection has failed". I lost my time in attempts to connect to Oracle DB 8, but have not results. After that i hacked button "Query DBMS" at "Features" tab, pressed it and when get error "ORA-03134: Connections to this server version are no longer supported.".
    Therefore Oracle 8 DB as datasource not supported. Am i right?
    4. In sample repository i added oracle DB 10 as datasource, then added two dual tables and their connection to all layers.
    Now i open BI Answers, and trying to create report with one dummy column, Now i have this error:
    Error
         View Display Error
    Odbc driver returned an error (SQLExecDirectW).

    Turribeach, Thanks for you time.
    1. It was not a question
    3. Yes, i have read platforms, but not supported datasources. Now i see, that BI 11g support as datasource Oracle DB 9.2.0.7 or higher. I am sorry.
    4. I'm using OCI connection type
    Now i recreate Database in Physical schema and answers is showing report data for me! But only from one table, when i use columns from to tables from one datasource, i geting error:

    Does anybody have the same problem like this? I've used the same method in my previous project to create oracle.jbo.domain.Date with current time using java.sql.Timestamp, but I don't know why this error happened.

  • Problem with Data Model and Analysis View

    I create an analyze in BI Publisher and then i create a data model using this object.
    When i try to generate an XML with a number of rows the BI Publisher return an empty XML (Only with de DATA_DS tags but no data).   To bypass this problem i make and XML file by hand and this allow me to create reports and design it but when i try to view the reports i got the message that says "No Data Found".
    So i was check the analysis and all looks appears to be fine,  In the results tab it show me a complete table with the data i was looking to use.
    So i try to repeat the error and when  i try to create the XML for the Data Model i found this two error in the logs:

    As i understand there is has a reference to a null value but i cant find what column of the analysis has the problem.
    Any ideas about how to solve or debug this?
    Thanks

    I follow your instructions and it works fine. I can create the XML and the reports can show data.
    So, i already know that there is no problem with the data and with the BI Publisher installation but i still doesn know what is the problem with the analysis view that fails.
    Any idea how to debug it?
    Thanks.

  • Please Help:  A Problem With Oracle-Provided 'Working' Example

    A Problem With Oracle-Provided 'Working' Example Using htp.formcheckbox
    I followed the simple steps in the Oracle-provided example:
    Doc ID: Note:116534.1
    Subject: How to use checkbox in webdb for bulk update using webdb report
    However, when I select a checkbox and click on the Update button, I get a "ORA-01036: illegal variable name/number" error. Please advise. This was a very promising feature.
    Fred
    Below are step-by-step instructions provided by Oracle to create this "working" example:
    How to use a checkbox in WEBDB 2.2 report for bulk update.
    PURPOSE
    This article shows how checkbox can used placed on WEBDB report
    and how to use it.
    SCOPE & APPLICATION
    The following example to guide through the steps to create a working
    example of this.
    In this example, the checkbox is used to select the records. On clicking
    the update button, the pl/sql procedure is called which will update col1 to
    the string 'OK'.
    After the update is done, the PL/SQL procedure calls the report again.
    Since the report only select records where col1 is null, the updated
    records will not be displayed when the report is called again.
    Step 1 - Create Table
    From Sqlplus, log in as scott/tiger and execute the following:
    drop table chkbox_example;
    create table chkbox_example
    (id varchar2(10) not null,
    comments varchar2(20),
    col1 varchar2(10));
    Step 2 - Insert Test Data
    From Sqlplus, still logged in as scott/tiger , execute the following:
    declare
    l_i number;
    begin
    for l_i in 1..50 loop
    insert into chkbox_example values (l_i, 'Comments ' || l_i , NULL);
    end loop;
    commit;
    end;
    Step 3 -Create SQL Query based WEBDB report
    Logon to a WEBDB site which has access to the database the above tables are created.
    Create a SQL based Report.
    Name the report :RPT_CHKBOX
    The select statement for the report is :
    select c.id, c.comments, c.col1,
    htf.formcheckbox('p_qty',c.id) Tick
    from SCOTT.chkbox_example c
    where c.col1 is null
    In Advanced PL/SQL, (REPORT, Before displaying the form), put the following code
    htp.formOpen('scott.chkbox_process');
    htp.formsubmit('p_request','Update');
    htp.br;
    htp.br;
    Step 4 - Create a stored procedure in the database
    Log on to the database as scott/tiger and execute the following to create the
    procedure.
    Note: Replace WEBDB to the appropriate webdb user for your installation.
    In my database, I had installed webdb using WEBDB username, hence user webdb owns
    the packages.
    create or replace procedure chkbox_process
    ( p_request in varchar2 default null,
    p_qty in wwv_utl_api_types.vc_arr ,
    p_arg_names in wwv_utl_api_types.vc_arr ,
    p_arg_values in wwv_utl_api_types.vc_arr
    is
    i number;
    begin
    for i in 1..p_qty.count loop
    if p_qty(i) is not null then
    begin
    update chkbox_example
    set col1 = 'OK'
    where chkbox_example.id = p_qty(i);
    end;
    end if;
    end loop;
    commit;
    /* To Call Report again after updating */
    SCOTT.RPT_CHKBOX.show
    (p_request=>'Run Report',
    p_arg_names=>webdb.wwv_standard_util.string_to_table2(' '),
    p_arg_values=>webdb.wwv_standard_util.string_to_table2(' '));
    end;
    Summary
    There are essentially 2 main modules, The WEBDB report and the pl/sql procedure (chkbox_process)
    A button is created via the advanced pl/sql coding which shows on top of the report. (The
    button cannot be placed at the bottom of the report due to the way WEBDB creates the procedure
    internally)
    When any button is clicked on the report, it calls the pl/sql procedure chkbox_process.
    The procedure is called , WEBDB always passes the parameters p_request,p_arg_names and o_arg_values.
    p_qty is another parameter that we are passing additionally, This comes from the checkbox created
    using the htf.formcheckbox in the report select statement.
    The pl/sql procedure calls the report again after processing. This is done to
    show how to call the report.
    Restrictions:
    -The Next and Prev buttons on the report will not work.
    So it is important that the report can fit in 1 page only.
    (This may mean that you will not select(not ticked) 'Paginate' under
    'Display Option' in the WEBDB report. If you do this,
    then in Step 4, remove p_arg_names and p_arg_values as input parameters
    to the chkbox_process)

    If your not so sure you can use the instanceof
    insurance,
    Object o = evt.getSource();
    if (o instanceof Button) {
    Button source = (Button) o;
    I haven't thoroughly read the thread, but I use something like this:if (evt.getSource() == someObjRef) {
        // do that voodoo
    ]I haven't looked into why you'd be creating a new reference...

    I guess the weblogic.jar is not included in the studio.
    So, i added weblogic.jar (Weblogic 10.3) and wlclient.jar (Weblogic 10.3)
    It is working in my simple java code. But, still not working in BPM Studio.

  • Problem with special characters and xmldom.writetoclob

    Hi!
    I have a problem with oracle parser in pl/sql.
    My situation:
    i have a clob with valid xml with for example decoded characters:
    (spaces between & and # are for good representing characters by browser - in really there is no spaces)
    <xml>
    <any><![CDATA[ & #187; ]]> text <![CDATA[ & #187; ]]></any>
    </xml>
    i read this xml from clob, parse it and put into another clob by using
    xmldom.writetoclob procedure.
    And in second clob i have"
    <xml>
    <any>& #38;#187; text & #38;#187; </any>
    </xml>
    (ampersand is representing as & #38; !) Why there is not the cdata sections ?
    Why the value of these sections changed?
    Any ideas? I'm using newset xdk (9202) in 8.1.7.3 database.
    Please help!

    Hi John,
    According to your description, my understanding is that the Author showed incorrect character in SharePoint 2013 search result page.
    I tested the same scenario per your post in my environment, and the Müller showed correctly in SharePoint search result page.
    I recommend to reset the index in Search Service Application and run a full crawl to see if the issue still occurs.
    Best regards.
    Thanks
