Dequeuing from AQ Using Java

I want to dequeue messages from a queue and process them using a Java program. I understand that the asynchronous notification facility is not available for Java. Is there another way I can receive the messages and process them without having to continually pool the queue?

OTN has some sample apps that use AQ with XML messages:
[list][*]WebStore B2B Exchange
[*]B2B with XML
[list]

  • How to send sms to mobile from tomcatserver using java code?

    Hi,
    Could you please let me know that,
    How to send sms to mobile from tomcatserver using java code? Please provide the code snippet.
    Thanks in advance.

    Yes, but something needs to send that message. You can't just take an arbitrary computer and send an SMS, it does not have the hardware to do that.
    So either you have a mobile through which you do that or more likely - you use some sort of online service to do it. Whatever choice you make will determine what code you will have to write to get it done. Nobody is going to deliver the code to you, that's your job. It is also your job to figure out what service you are going to use.

  • How to extract the number from image using java

    Hello every one
    i want to develope a project which can extract the number from image
    that i can use as inter or String or char.
    Is there any API in java which provide this type of facility.
    right now i m using java 5
    thanks in Advance
    Jignesh

    In my project i have a image in that i have a
    co-ordinate (x,y) I am still puzzled as to what you seek. It sounds to me like you have a point (x, y) represented by p. in java it's just p.getX() p.getY()
    i want to convert that cordinate to numeric form,
    i mena i want to use that cordinate in somewhere else
    in project.point.getX() point.getY()
    So need to convert it into numeric form u can called
    it OCR also.OCR is optical character recognition. If I want out and took a picture of the US Declaration of Independence and then wanted the words on the parchement in the picture in text form, then I would run the picture through a software program and it would try to optically recognise what lettering and number were present in the picture. In the end, I would have a text of what is written on the US Declaration of Independence.
    Is that what you want?

    <Humidity>89.9</Humidity>
    </Weather>
    </DLList>
    Please help.Let me know if any other information is required
    Thanks

    OK, here goes :
    For the example, I'll use a TB_DISTRICT table with the following structure :
    create table tb_district (
    sr_no number(3),
    district_name varchar2(100)
    );loaded with data from this page :
    http://india.gov.in/knowindia/districts/andhra1.php?stateid=KA
    and this XML document (one additional record compared to the one you posted) :
    <DLList xmlns="http://www.test.com/integration/feed" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <Weather>
    <StateName>Karnataka</StateName>
    <ForecastName>Bagalkote</ForecastName>
    <Humidity>89.9</Humidity>
    </Weather>
    <Weather>
    <StateName>Karnataka</StateName>
    <ForecastName>Devengiri</ForecastName>
    <Humidity>89.9</Humidity>
    </Weather>
    <Weather>
    <StateName>Karnataka</StateName>
    <ForecastName>Dharwad</ForecastName>
    <Humidity>70.1</Humidity>
    </Weather>
    </DLList>In order to access the XML, I'll also use this Oracle directory object :
    create directory test_dir as 'D:\ORACLE\test';Final relational tables are :
    create table BUSINESS_TABLE
      STATE         VARCHAR2(30),
      DISTRICT_NAME VARCHAR2(30),
      HUMIDITY      NUMBER
    );and
    create table REJECT_TABLE
      STATE         VARCHAR2(30),
      DISTRICT_NAME VARCHAR2(30),
      HUMIDITY      NUMBER,
      ERROR_MESSAGE VARCHAR2(500)
    );With XMLTable function, we can easily break the XML into relational rows and columns ready to use for DML :
    SQL> alter session set nls_numeric_characters=". ";
    Session altered
    SQL>
    SQL> SELECT *
      2  FROM XMLTable(
      3    XMLNamespaces(default 'http://www.test.com/integration/feed'),
      4    '/DLList/Weather'
      5    passing xmltype(bfilename('TEST_DIR','test.xml'), nls_charset_id('CHAR_CS'))
      6    columns
      7      state         varchar2(30) path 'StateName'
      8    , district_name varchar2(30) path 'ForecastName'
      9    , humidity      number       path 'Humidity'
    10  )
    11  ;
    STATE                          DISTRICT_NAME                    HUMIDITY
    Karnataka                      Bagalkote                            89.9
    Karnataka                      Devengiri                            89.9
    Karnataka                      Dharwad                              70.1
    Then with a multitable insert, we load both the business table and the reject table (if the district name does not exist in TB_DISTRICT) :
    SQL> INSERT FIRST
      2    WHEN master_district_name IS NOT NULL
      3      THEN INTO business_table (state, district_name, humidity)
      4                VALUES (state, district_name, humidity)
      5    ELSE INTO reject_table (state, district_name, humidity, error_message)
      6              VALUES (state, district_name, humidity, 'Invalid district name')
      7  WITH xml_data AS (
      8    SELECT *
      9    FROM XMLTable(
    10      XMLNamespaces(default 'http://www.test.com/integration/feed'),
    11      '/DLList/Weather'
    12      passing xmltype(bfilename('TEST_DIR','test.xml'), nls_charset_id('CHAR_CS'))
    13      columns
    14        state         varchar2(30) path 'StateName'
    15      , district_name varchar2(30) path 'ForecastName'
    16      , humidity      number       path 'Humidity'
    17    )
    18  )
    19  SELECT x.*
    20       , t.district_name as master_district_name
    21  FROM xml_data x
    22       LEFT OUTER JOIN tb_district t ON t.district_name = x.district_name
    23  ;
    3 rows inserted
    SQL> select * from business_table;
    STATE                          DISTRICT_NAME                    HUMIDITY
    Karnataka                      Dharwad                              70.1
    SQL> select * from reject_table;
    STATE                          DISTRICT_NAME                    HUMIDITY ERROR_MESSAGE
    Karnataka                      Bagalkote                            89.9 Invalid district name

    Hi,
    I have a problem with synchronization of the java commands.
    In the Before Parammeter Form trigger, I have:

    order by substr(nome, 11);
    begin
    -- Create the context for logged user

    if PK_SCA.SCA_GET_USER_RIGHTS(:sca_module_name, :AUTHID) IS NULL then
    srw.message(100, 'Access denided!');
    return (FALSE);
    end if;

    i := i + 1;
    if i = 1 then
    v_txt := '<OPTION SELECTED VALUE="' || reg.codigo || '">' || reg.nome;

    rt := RUNTIME.GetRuntime();
    proc := RUNTIME.exec(rt,'rm ' || :p_file);
    return (TRUE);
    end;
    The problem is that there isn't a "synchronize" command, and the
    RUNTIME.exec(rt,'rm ' || :p_file) don't works (it does nothing) because
    the SRW.SET_AFTER_FORM_HTML has a large delay and the following
    command is ignored.
    How can I solve it?
    thanks,
