Escape codes for substring and bold????

i am writing a servlet to process a form i made with HTML.
The servlet works with the form data and sends an e-mail.
I use escape characters for returns, tabs and stuff like that. Is there a code to BOLD or SUPERSCRIPT a peice of the output?
THANKS!

The HTML code for bold is <b>bold</b>, if that's what you were asking. And there's <sub> too. If you weren't asking that, what were you asking?

    Typically the way that you redeem a gift card is to go to either the app store or iTunes - go to the featured tab in the app store or the music tab in iTunes - swipe to the bottom of the screen. Tap on Reedem at the bottom and go from there.

  • Language codes for 'english' and 'english-2' must differ?

    I am trying to build my project but as I do I get the following pop up: Compiler: Language codes for 'english' and 'english-2' must differ. What do I need to change?

    You have added a language to your project which you don't need. Look in the outline view at the bottom for the folder called langauges, then delete the second one. Both will be English and this cannot be the case on a DVD - the player will not know which assets to use on a menu if there are two langauges the same.
    The languages are used when you want to create a disc that will display the correct menu backgrounds when used in players in different countries - the DVD player settings will have a language set up, and the DVD will use the appropriate language files to construct the menus accordingly.

  • Lanuage codes for 'english' and 'english-2' must differ ERROR

    Hello, I'm trying to burn a single layer DVD for a clent of mine and whenever I pressthebuiold/format button a error that states: (lanuage codes for 'english' and 'english-2' must differ) pop up. I have been using DVD studio for some time now and have never ran into this. I don't belive I have changed any settings. anyone have any answers?
    thank you for your time
    Mike

    Hi Mike
    This is a common problem. You've added a second language by mistake and it's the same as the 1st one.
    Look at the bottom of your outline and you'll see "English" and "English-1". Delete "English-1" and re-build.

  • Escape codes for laser printer Kyocera FS-3920dn in reports 6i

    Hi,
    I use many reports for printing on laser printer Kyocera FS-3920DN. But now I need print some reports on special performed paper. For this we added 1 paper tray to printer ( Now we have 2 trays in printer ). How can I define for new reports which tray have to use ??? I wish to specified for report2.rep to use automaticly tray 2. Its a way through PRT file use escape codes ?? Have you any experience pls??

    In the report itself you can use:
    SRW.SET_PRINTER_TRAY('tray');
    see the online help.
    We do it differently, though. Our printers have 2 trays, one with blank paper and one with pre-printed logo paper.
    On each PC there are two printers defined (PRINTER_BLANk and PRINTER_LOGO). They point to the same printer, just a different tray.

  • XML escape sequences for brackets and xmltype.extract

    G'day gang, I'm hoping somebody would be kind enough to help me with the following query please.
    I have a web service that is returning the following XML stream into an XMLType in the database:
    <OutOfStockAdviceResponse xmlns="http://abc.org/abcWebServices">
      <OutOfStockAdviceResult>
      & lt;Response& lt;ResponseCode& gt;0& lt;/ResponseCode& gt;
      & lt;ResponseMessage& gt;Successful& lt;/ResponseMessage& gt;
      & lt;/Response& gt;
      </OutOfStockAdviceResult>
    </OutOfStockAdviceeResponse>You'll note the & lt; and & gt; characters (note to display these strings in OTN I've had to add a space between the & and the lt; or gt;. The spaces don't actually occur in the real XML data coming back).
    What's odd about this XML stream coming back is it is mixing the use of the XML angle brackets with the escape character equivalents (eg. & lt; and & gt;) half way through the XML stream. Is this valid for an XML stream to do this? Any idea what would cause this? Is it possible the source is creating 2 separate XML streams using different character sets and then concatenating them to get this result?
    The reason I'm asking is I'm attempting via PL/SQL to extract the ResponseCode and ResponseMessage tags with the following code:
      v_response_code := XMLType.extract(v_response,
          '/OutOfStockAdviceResponse/OutOfStockAdviceResult/Response/ResponseCode/text()',
          'xmlns="http://abc.org/abcWebServices"').getnumberval;
      v_response_msg  := XMLType.extract(v_response,
          '/OutOfStockAdviceResponse/OutOfStockAdviceResult/Response/ResponseMessage/text()',
          'xmlns="http://abc.org/abcWebServices"').getstringval;Both calls are failing with:
    ORA-30625: method dispatch on NULL SELF argument is disallowedCan anybody point me in the right direction for solving this issue? Is there a way to get the xmltype.extract function to recognize the different character encoding schemes (if they do indeed actually exist)?
    Any help appreciated.
    CM.
    PS. Apologize for the weak subject line.

    Since that Serviceis actually returning the escaped representation of '<' and '>' inside OutOfStocAdviceResult, the XML Parser considers that whole block of text to be simply a text node child the parent element, not valid XML. Hence the result of your XPath expressions is null and you get the ORA-30625 when you try to invoke the getNumberVal() and getStringVal() methods, which is the PL/SQL equivilant of a Java Null Pointer Exception.
    You can solve it as follows...
    set define off
    set serveroutput on
    declare
      v_response xmltype;
      v_response_code number(4);
      v_response_msg varchar2(64);
      v_xmltext varchar2(256);
      v_OutOfStockResponse xmltype := xmltype(
    '<OutOfStockAdviceResponse xmlns="http://abc.org/abcWebServices"> 
      <OutOfStockAdviceResult>
        & lt;Response& gt;& lt;ResponseCode& gt;0& lt;/ResponseCode& gt;& lt;ResponseMessage& gt;Successful& lt;/ResponseMessage& gt;& lt;/Response& gt; 
      </OutOfStockAdviceResult>
    </OutOfStockAdviceResponse>');
    begin
      select extractValue(v_OutOfStockResponse,'/OutOfStockAdviceResponse/OutOfStockAdviceResult','xmlns="http://abc.org/abcWebServices"')
        into v_xmltext
        from dual;
       dbms_output.put_line('Text = ' || v_xmlText);
       v_response := xmltype(v_xmltext);
       v_response_code := v_response.extract('/Response/ResponseCode/text()').getnumberval();
       v_response_msg  := v_response.extract('/Response/ResponseMessage/text()').getstringval();
       dbms_output.put_line('Code = ' || v_response_code);
       dbms_output.put_line('Msg = ' || v_response_msg);
    end;Note that like you I had to insert space characters between in the 'lt' and 'gt' escape sequences...
    When this is run you get the following
    SQL> set define off
    SQL> set serveroutput on
    SQL> --
    SQL> declare
      2    v_response xmltype;
      3    v_response_code number(4);
      4    v_response_msg varchar2(64);
      5    v_xmltext varchar2(256);
      6    v_OutOfStockResponse xmltype := xmltype(
      7  '<OutOfStockAdviceResponse xmlns="http://abc.org/abcWebServices">
      8    <OutOfStockAdviceResult>
      9      & lt;Response& gt;& lt;ResponseCode& gt;0& lt;/ResponseCode& gt;& lt;ResponseMessage& gt;Successful& lt;/ResponseMessage& gt;& lt;/Response& gt;
    10    </OutOfStockAdviceResult>
    11  </OutOfStockAdviceResponse>');
    12  begin
    13    select extractValue(v_OutOfStockResponse,'/OutOfStockAdviceResponse/OutOfStockAdviceResult','xmlns="http://abc.org/abcWebServices"')
    14      into v_xmltext
    15      from dual;
    16     dbms_output.put_line('Text = ' || v_xmlText);
    17     v_response := xmltype(v_xmltext);
    18     v_response_code := v_response.extract('/Response/ResponseCode/text()').getnumberval();
    19     v_response_msg  := v_response.extract('/Response/ResponseMessage/text()').getstringval();
    20     dbms_output.put_line('Code = ' || v_response_code);
    21     dbms_output.put_line('Msg = ' || v_response_msg);
    22  end;
    23  /
    Text =
    <Response><ResponseCode>0</ResponseCode><ResponseMessage>Successful</ResponseMes
    sage></Response>
    Code = 0
    Msg = Successful
    PL/SQL procedure successfully completed.
    SQL>Basically we extract the encoded text using extractValue() which will de-escape the escapted characters and then create a new XMLType which we can operate on

  • Reg:T-CODE for open and close period for materials(new plant).

    hi sap guru's
    T-code for following process
        can anybody send me , how to create calendar to new plant . and what is the T-code to be use for open and close period of materials for new plant.
    thanks
    sakthi..

    Hi Sakthi,
    I am assuming that you are asking about the factory calendars which are assigned while difing the plant.
    Factory calendars are created through transaction "SCAL".
    Opening and closing of MM periods can be done through transaction MMPV.This is based on the company code.Before using MMPV ,you can look the last opened period in the transaction MMRV.
    Reward points if it helps.

  • Parameters for substr and dbms_lob.substr

    The syntax for substr in SQL functions and for the function in dbms_lob package is not matching and hence confusing for programmers. It will be less confusing if parameters for both functions are of the same order.
    In Sql functions the the syntax for substr is substr(string, offset, amount)
    In dbms_lob package the syntax for the substr function is dbms_lob.substr(lob_loc, amount, offset)
