  • How to run and compile a java servlet on Tomcat?

    Hi, I am very new to servlets in Tomact.
    I went to the java tutorial and from the address below I copy an example (SimpleServlet).I try to run and compile it in Tomcat, But I don't know how can I do that. I appreciate if somebody tell me the command line for compiling and running this example and the necassary steps. (My Tomcat is installed perfactly).
    http://java.sun.com/docs/books/tutorial/servlets/overview/simple.html
    Thankx

    Hello,
    I have the similar question.
    Instead of going thru sun's tutorial, I tried onjava's ("http://www.onjava.com/pub/a/onjava/2001/04/19/tomcat.html?page=1").
    I could see the jsp page, but when I tried to add a servlet, I got an error "Page not found". I followed exactly the same way they describe. The only thing I noticed was the resulting page on the tutorial had the URL of ".../servlet/...".
    Is this "servlet" directory something we are supposed to create our own? If so, under what directory? Or do we need to set up anything in order for the servlet to be referenced that way?
    Thanks in advance.

  • How to run report from form using run_object_report

    I AM USNING FORMS9I/REPORTS 9I , HOW TO RUN REPORT FROM FROM USING RUN_REPORT_OBJECT AND HOW
    TO PASS PARAMETER AS WE DID IN RUN_REPORTS PLEASE HELP ME

    here an example !
    I hope this example you can use it
    PROCEDURE pr_reporte IS
    BEGIN
    DECLARE
         repid REPORT_OBJECT;
    v_rep VARCHAR2(100);
    rep_status Varchar2(20);
    d1 DATE;
    d2 DATE;
    BEGIN
         d1 := :GLOBAL.DIA_INI;
         d2 := :GLOBAL.DIA_FIN;
         repid := find_report_object('rep_lab02');
         SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER,'p_fec_uno='||to_char((add_months(last_day(d1),-1) +1),'DD/MM/YYYY')||' '||
         'p_fec_dos='||to_char(d2,'DD/MM/YYYY'));
         SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESFORMAT,'pdf');
         v_rep := RUN_REPORT_OBJECT(repid);
         rep_status := report_object_status(v_rep);
         WHILE rep_status in ('RUNNING','OPENING_REPORT','ENQUEUED') LOOP
              rep_status := report_object_status(v_rep);
         END LOOP;
         IF rep_status = 'FINISHED' then
              WEB.SHOW_DOCUMENT('/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=repserver','_blank');
         ELSE
              ventana('E','error reporte no encontrado','S');
         END IF;
    END;
    END;
    The 'rep_lab02' is the name of the report that you give in the node reports
    p_fec_uno and p_fec_dos they are the parameters in the report
    repserver is the name of server created with rwserver

  • How to run and use LCRE

    Dear all,
    I downloaded and installed the trial LiveCycle ES3 Server of Jboss from below link.
    http://www.adobe.com/content/dotcom/en/devnet/livecycle/downloads.html
    After installation, I don't know how to make the configuration or how to run LCRE, which is the executive one?
    I just want to use LCRE to extend the PDF form. Thanks.

    What is your usecase ? Do you want to Reader Extend PDF files so that users can fill forms using Adobe Reader ?
    Is the number of users who would receive Reader Extended documents more than 500?
    And do you reader extend large volume of documents?
    If the answer is yes to any of the above questions then LC RE is the right product to use

    Gurus,
    Please suggest if there is a way to run .bat files using DAC ? I suppose it can be done by configuring Execution Type as External Program. Please suggest how can this be achieved.
    Thanks

    I performed the same steps given in the link and ran the ex plan, but the task shows running and never completes. In my case i have created bat file for a different purpose (not for purging cache).
    Is the path shown in Step 5 the default path or it can be any path ? Please suggest.

    Lavanya,
    This question relates to shell scripting and in IMO it is not an oracle question.
    I have made some initial assumptions before my proposed solution.
    PLEASE note that this is untested, but can just guide you as a template for solving your problem.
    Assuming that you have properly set up the control file and mapped each and every table in it as per the file information which you have..
    Assuming the text file to be in the format of : ------ (as suggested by other posters earlier, this file holds instructions about the file and table mapping which shall be used by your sqlldr process.)
    tmp.txt:
    text_file_1-------------should goes to----customer_info_table
    text_file_2------------should goes to------customer_address_table
    text_file_3-----------should goes to-------customer_order_table
    while read line
    do
    SQLLDR CONTROL=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.ctl,
    LOG=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.log,
    BAD=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.bad,
    DATA=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.txt
    USERID=scott/tiger
    done <tmp.txtAll I am trying to run from the above shell script is : -- PLEASE TEST it if it matches your requirement.
    SQLLDR CONTROL=text_file_1.ctl, LOG=text_file_1.log, BAD=text_file_1.bad, DATA=text_file_1.txt USERID=scott/tiger
    SQLLDR CONTROL=text_file_2.ctl, LOG=text_file_2.log, BAD=text_file_2.bad, DATA=text_file_2.txt USERID=scott/tiger
    SQLLDR CONTROL=text_file_3.ctl, LOG=text_file_3.log, BAD=text_file_3.bad, DATA=text_file_3.txt USERID=scott/tigerRepeating my assumptions, I assume you have all those files required for SQLLDR process to run (ctl file, data file...)

  • Error message when trying to play music on computer states The song ... could not be used because the original file could not be found.  However, my library shows how many items and the GBs used.  How do I locate the files?

    When I try to play my iTunes music on my computer, an error message comes up and state "The song (title of song) could not be used because the original file could not be found.  Would you like to locate it?
    When I click on Locate It, I cannot find where the music file may be located.  Does anyone have any suggestions?
    This all occurred when I attempted to do a backup to an external hard drive.  Unbeknownest to me, the files did not copy over and do not appear on the external hard drive. 
    When I open my iTunes library, at the bottom of my music list it shows how many songs and the GBs, so it appears that the files are still there; however, cannot be located.
    Thank you.

    Hi angela dfromtx,
    When tracks in iTunes display a it means the file cannot be located; it may have been moved or deleted. You'll have to locate the file manually if it is still available. For more information refer to the following article:
