How to use Unicode_More precisions

This is my problem
i want to code de text into between two "" in a given file.i use Stringtokenizer to select the tokens requered.
after gettting the tokens, i have to code them, i.e replace each caracter by its corresponding unicode, something likes \u00ff for exemple.
after coding all the tokens in the file i display the text.
i'm sorry for my bad english;
thank for help

Don't use String tokeniser use a char array and pass each one by reference as a parameter eg
new Unicd uni1 = getUnicode(aChar)
and have a seperate class file ie: Unicd.java to store each char refence and return the appropriate unicode letter-num combo

  • How to use the set functions effectively in webi ,please let me know with detail

    how to use the set functions effectively in webi ,please let me know with detail

    Hi,
    we use use set functions on heirarchies with aggregate functions mostly .
    If you include member_set, Min returns the minimum value of the aggregated data for all members in the member set.
    Member_set can include multiple sets separated by semicolons (;).
    The list of member sets must be enclosed in {}.
    If the member set expression does not specify a precise member or node, the hierarchy referenced must be present in the table, then the member set expression references the current member in the hierarchy in the table. If the hierarchy is not in the table, the function returns the message #MULTIVALUE.
    Eg .
    1)     Ancestor
    =Sum([YTD] ; {Ancestor([Test Hierarchy];2)})
    2)     IsLeaf
    =[Test Hierarchy].IsLeaf
    You can use this function when you want to show your Measure only at lower level .
    3)     .Depth
    =[Test Hierarchy].Depth
    This is also function used with hierarchy to find Level of Members .

  • How to use Changed Data Capture?

    Hello,
    I want to use CDC to load my DW in real time. I am testing ODI in that mode.
    I have two tables:
    SRC Employe (empl_ID, name, surname, salaire, age) and TRG Employe( empl_ID, name, surname, CreDate, UpdDate) on SQL Server 2005. I wish to load data from SRC Employe to TRG Employe. I want that this data are charged in real time.
    how to do this? I know that I must use OdiWaitForData and OdiWaitForLogData but in ODI documentations, explanations are not sufficient.
    how to use OdiWaitForData and OdiWaitForLogData?
    thanks in advance
    Billyrose

    Hello,
    but when I created a package and added OdiWaitForLogData, pb began. the step that has OdiWaitForLogData succeed. but my interface failed. the step "Load Data" failed.why?
    There is no reason for that. WaitForXXX does not affect the data stored in the CDC infrastructure, but just detects it.
    - What type of CDC are you using: simple or consistent set?
    - Did your interface used journal data only?
    - What error did you get precisely on the "Load Data" task?
    Could you tell me how to schedule a package?For scheduling, I think you should have a look at "Generating a Scenario" in the user manual. under the generated scenario node, you'll see the schedule node and you can start scheduling from here.

  • How to use case when function to calculate time ?

    Dear All,
    May i know how to use case when function to calculate the time ?
    for the example , if the First_EP_scan_time is 12.30,  then must minus 30 min.  
    CASE WHEN FIRSTSCAN.EP_SHIFT <> 'R1' AND FIRSTSCAN.EP_SHIFT <> 'R2'
    THEN ROUND(CAST((DATEDIFF(MINUTE,CAST(STUFF(STUFF((CASE WHEN SHIFTCAL.EP_SHIFT = 'N1'
    THEN CONVERT(VARCHAR(8),DATEADD(DAY,+1,LEFT(FIRSTSCAN.EP_SCAN_DATE ,8)),112) + ' ' + REPLACE(CONVERT(VARCHAR(8),DATEADD(HOUR,+0,SHIFTDESC.EP_SHIFT_TIMETO + ':00'),108),':','')
    ELSE LEFT(FIRSTSCAN.EP_SCAN_DATE ,8) + ' ' + REPLACE(CONVERT(VARCHAR(8),DATEADD(HOUR,+0,SHIFTDESC.EP_SHIFT_TIMETO + ':00'),108),':','') END),12,0,':'),15,0,':') AS DATETIME),CAST(STUFF(STUFF(LASTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME)) / 60.0 - 0.25) AS FLOAT),2)
    ELSE ROUND(CAST((DATEDIFF(MINUTE,CAST(STUFF(STUFF(FIRSTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME),CAST(STUFF(STUFF(LASTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME)) / 60.0) AS FLOAT),2) END AS OTWORK_HOUR

    Do not use computations in a declarative language.  This is SQL and not COBOL.
    Use a table of time slots set to one more decimal second of precision than your data. You can now use temporal math to add it to a DATE to TIME(1) get a full DATETIME2(0). Here is the basic skeleton. 
    CREATE TABLE Timeslots
    (slot_start_time TIME(1) NOT NULL PRIMARY KEY,
     slot_end_time TIME(1) NOT NULL,
     CHECK (start_time < end_time));
    INSERT INTO Timeslots  --15 min intervals 
    VALUES ('00:00:00.0', '00:14:59.9'),
    ('00:15:00.0', '00:29:59.9'),
    ('00:30:00.0', '00:44:59.9'),
    ('00:45:00.0', '01:00:59.9'), 
    ('23:45:00.0', '23:59:59.9'); 
    Here is the basic query for rounding down to a time slot. 
    SELECT CAST (@in_timestamp AS DATE), T.start_time
      FROM Timeslots AS T
     WHERE CAST (@in_timestamp AS TIME)
           BETWEEN T.slot_start_time 
               AND T.slot_end_time;

  • How to use catch ---CATCH ... ENDCATCH

    Hi Expert:
          How to use CATCH ... ENDCATCH  the statement, would you please explain it with an example non-numeric exception.  that is to say, if it is not a number , an exception would be received and handled. Would you please  give me more discription about how to handle it?
    couldn't thank you more.
    Best regards.

    Hi,
    Variants:
    1. CATCH SYSTEM-EXCEPTIONS except1 = rc1 ... exceptn = rcn.
    Effect
    You can catch ABAP runtime errors in the processing block enclosed in the CATCH ... ENDCATCH statements.
    Note the following:
    rc1 ... rcn must be numeric literals.
    CATCH ... ENDCATCH may be placed anywhere where IF ... ENDIF (for example) may occur. It is local, not cross-event.
    It may be nested to any depth.
    It only catches runtime errors in the current call level. This means, for example, that runtime errors resulting from PERFORM- or CALL FUNCTION statements are not trapped by CATCH ... ENDCATCH.
    Specifying a SYSTEM-EXCEPTION
    You can specify the following as except1 ... exceptn:
    The error ID of the runtime error that you want to catch (ex. CONVT_NO_NUMBER)
    An ERROR class
    OTHERS, any remaining catchable errors.
    Catchable runtime errors are assigned to ERROR classes. If you specify an ERROR class, all of its associated runtime errors will be caught. If you specify OTHERS, the system traps all catchable runtime errors.
    Keyword dependency
    Within CATCH ... ENDCATCH, a particular runtime error will only be caught if it is caused by a particular keyword.
    You can find out the keywords with which you can catch a particular runtime error:
    In the keyword documentation. This specifies the catchable runtime errors for the keyword,
    In the
    Assignment of keywords to ERROR classes.
    If the system catches a runtime error,
    the current processing block is interrupted, and the program processing jumps directly from the statement where the error occurred to the ENDCATCH statement. This occurs irrespective of the number of control structures (IF, DO, LOOP, SELECT, CATCH, etc, ...) bypassed in so doing.
    No guarantees can be made about the contents of any fields involved in the runtime error following the ENDCATCH statement.
    The
    return code
    is set as follows:
    After the ENDCATCH statement, SY-SUBRC is set to the corresponding value "rcn". This is the value assigned to the runtime error or ERROR class in the CATCH statement. If there is more than one "exceptn = rcn" expression in the runtime error, the "rcn" from the first expression is used. This is particularly significant if there are two ERROR classes which contain the same runtime error.
    If the system does not catch a runtime error, the value of SY-SUBRC after the ENDCATCH statement is 0.
    Example
    Nested Structures
    The example below calculates the factorial of the program parameter "fact ". If "fact" is too large, the system catches the runtime error COMPUTE_BCD_OVERFLOW . In this case, the system leaves the current DO...ENDDO loop at the MULTIPLY... statement, and jumps to the ENDCATCH statement.
    PARAMETERS fact TYPE i.
    DATA: fact_save TYPE i,
    res(16) TYPE p.
    ARITHMETIC_ERRORS contains COMPUTE_BCD_OVERFLOW ***
    CATCH SYSTEM-EXCEPTIONS ARITHMETIC_ERRORS = 5.
    res = fact_save = fact.
    SUBTRACT 1 FROM fact.
    DO fact TIMES.
    MULTIPLY res BY fact. "<- COMPUTE_BCD_OVERFLOW
    SUBTRACT 1 FROM fact.
    ENDDO.
    ENDCATCH.
    IF sy-subrc = 5.
    WRITE: / 'Overflow! Factorial of', fact_save,
    'can not be calculated.'.
    ELSE.
    WRITE: / 'Factorial of', fact_save, 'gives', res.
    ENDIF.
    Examples
    Keyword Dependency
    In the first example, the runtime error CONVT_NO_NUMBER is caught during conversion with MOVE.
    In the second example, the runtime error cannot be caught, since the keyword SELECT has no primary conversion function.
    In the third example, the conversion takes place in an auxiliary field (MOVE 'abc' TO int.) andn the SELECT statement uses only operands with the same type. This enables the system to catch the runtime error.
    DATA I TYPE I.
    CONVERSION_ERRORS contains CONVT_NO_NUMBER ***
    CATCH SYSTEM-EXCEPTIONS CONVERSION_ERRORS = 1.
    MOVE 'abc' TO I. " <- Error: CONVT_NO_NUMBER
    ENDCATCH.
    IF SY-SUBRC = 1.
    ENDIF.
    TABLES SFLIGHT.
    CATCH SYSTEM-EXCEPTIONS CONVERSION_ERRORS = 1.
    SELECT * FROM SFLIGHT
    WHERE SEATSMAX = 'abc'. " <- Error: CONVT_NO_NUMBER
    ENDSELECT.
    ENDCATCH.
    TABLES SFLIGHT.
    DATA int LIKE SFLIGHT-SEATSMAX.
    CATCH SYSTEM-EXCEPTIONS CONVERSION_ERRORS = 1.
    MOVE 'abc' TO int. " <- Error: CONVT_NO_NUMBER
    SELECT * FROM SFLIGHT WHERE SEATSMAX = int.
    ENDSELECT.
    ENDCATCH.
    Note
    Using Runtime Error ID and ERROR Class
    You are recommended only to use ERROR classes in the CATCH statement wherever possible. Assignment of keywords to ERROR classes contains a simple description of which errors are covered by a particular ERROR class.
    You should only use the runtime error ID if the error situation can be very precisely defined. For more information about when runtime errors occur, see alphabetical list of all catchable runtime errors.
    Note
    Performance:
    The CATCH...ENDCATCH statements require about
    3-4 msn (standardized microseconds) of runtime, if no runtime error occurs.
    If the statements then have to catch a runtime error, they may require more runtime, depending on the type of the runtime error. In the least serious case, this will be another 3-4 msn. In more serious cases, it can be up to 20 msn. For most cases, the increased runtime will be around 5-10 msn.

  • Can't figure out how to use home sharing

    Since the latest couple iTunes updates, my family and I can not figure out how to use home sharing. Everyone in our household has their own iTunes, and for a long time we would just share our music through home sharing. But with the updates, so much has changed that we can no longer figure out how to use it.
    I have a lot of purchased albums on another laptop in the house, that im trying to move it all over to my own iTunes, and I have spent a long time searching the internet, and everything. And I just can't figure out how to do it. So.... how does it work now? I would really like to get these albums from my moms iTunes, onto mine. I would hate to have to buy them all over again.
    If anyone is able to help me out here, that would be great! Thanks!

    The problem im having is that after I am in another library through home sharing, I can't figure out how to select an album and import it to my library. They used to have it set up so that you just highlight all of the songs you want, and then all you had to do was click import. Now I don't even see an import button, or anything else like it. So im lost... I don't know if it's something im doing wrong, or if our home sharing system just isn't working properly.
    Thanks for the help.

    Batch processing usually involves using actions you have recorded.  In Action you can insert Path that can be used during processing documents.  Path have some size so you may want to only process document that have the same size.  Look in the Actions Palette fly-out menu for insert path.  It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

  • How to use airport time capsule with multiple computers?

    I'm sure there are some thread about this but i couldn't find it... so sorry for that but hear me out! =)
    I bought the AirPort Time Capsule to back up my MBP
    And so i did.
    then i thought "let give this one a fresh start" so i erased all of it with the disk utility and re-installed the MBP from the recovery disk.
    I dont want all of the stuff i backed up just a few files and some pictures so i brought that back.. so far so good.
    Now i want to do a new back up of my MBP so i open time machine settings, pick the drive on the time capsule and then "Choose" i wait for the beck up to begin, and then it fails.  It says (sorry for my bad english, im swedish haha) "the mount /Volume/Data-1/StiflersMBP.sparsebundle is already in use for back up.
    this is what i want:
    i want the "StiflersMBP.sparsebundle" to just be so i can get some stuf when i need them. it's never to be erased.
    i want to make a new back up of my MBP as if it's a second computer...
    so guys and girls, what is the easiest and best solution?
    Best regards!

  • ** How to use TO_DATE function in Stored Proc. for JDBC in ABAP-XSL mapping

    Hi friends,
    I use ABAP-XSL mapping to insert records in Oracle table. My Sender is File and receiver is JDBC. We use Oracle 10g database. All fields in table are VARCHAR2 except one field; this is having type 'DATE'.
    I use Stored procedure to update the records in table. I have converted my string into date using the Oracle TO_DATE function. But, when I use this format, it throws an error in the Receiver CC. (But, the message is processed successfully in SXMB_MONI).
    The input format I formed like below:
    <X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">
    Value in Payload is like below.
    <X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">TO_DATE('18-11-1991','DD-MM-YYYY')</X_EMP_START_DT>
    Error in CC comes as below:
    Error processing request in sax parser: Error when executing statement for table/stored proc. 'SP_EMP_DETAILS' (structure 'STATEMENT'): java.lang.NumberFormatException: For input string: "TO_DATE('18"
    Friends, I have tried, but unable to find the correct solution to insert.
    Kindly help me to solve this issue.
    Kind Regards,
    Jegathees P.
    (But, the same is working fine if we use direct method in ABAP-XSL ie. not thru Stored Procedure)

    Hi Sinha,
    Thanks for your reply.
    I used the syntax
    <xsl:call-template name="date:format-date">
       <xsl:with-param name="date-time" select="string" />
       <xsl:with-param name="pattern" select="string" />
    </xsl:call-template>
    in my Abap XSL.  But, its not working correctly. The problem is 'href' function to import "date.xsl" in my XSLT is not able to do that. The system throws an error. Moreover, it is not able to write the command 'extension-element-prefixes' in my <xsl:stylesheet namespace>
    May be I am not able to understand how to use this.
    Anyway, I solved this problem by handling date conversion inside Oracle Stored Procedure. Now, its working fine.
    Thank you.

  • Sender Mail Adapter - S/MIME - How to use it?

    Hi guys,
    I am trying to figure out how to use the S/MIME security parameter of the Sender Mail Adapter in PI 7.1.
    Could anyone point me to some useful documentation/examples/blogs ?
    Or perhaps explain what steps are involved when configuring this parameter?
    We are pulling emails from an Microsoft Exchange server.
    Many thanks,
    Aldo

    First of all one sender mail adapter has to be tight with a specific sender email address.
    The email has to be decrypted as whole, you cannot decrypt parts of it.
    Then you store certificates to secure store in J2EE server and point to it in send agreement, this should be equal to HTTPS setup
    Check security guide:
