Here is a good link that indicate that JavaBean is not only for applets
http://java.sun.com/docs/books/tutorial/javabeans/whatis/beanDefinition.html
quote:
The JavaBeans API makes it possible to write component software in the Java programming language. Components are self-contained, reusable software units that can be visually composed into composite components, applets, applications, and servlets using visual application builder tools. JavaBean components are known as Beans.

  • Need help regarding Java decoding of IMAP attachment (IOStream related ques

    Hi ,
    I need some help regarding the processing of an IMAP attachment , It is a basic IOStream related question I guess.
    I have some attachment to a mail , I try to fetch it using javamail and read the content and write it to a file , I was able to do it successfully when I was using stream.read( tempBuffer) function but when I started using stream.read( tempBuffer, 0, m_maxDataSize ); it is giving me following exception
    java.io.IOException: Error in encoded stream: needed at least 2 valid base64 characters, but only got 1 before padding character (=), the 10 most recent characters were: "/59PT/eXQ="
         at com.sun.mail.util.BASE64DecoderStream.decode(BASE64DecoderStream.java:259)
         at com.sun.mail.util.BASE64DecoderStream.read(BASE64DecoderStream.java:148)
    ***Here is the snippet of code that is running this:***
    m_contentObj = m_message.getContent();
    if(m_contentObj instanceof InputStream)
         System.out.println(" Content is type of InputStream");
         InputStream stream = (InputStream) m_contentObj;
         byte[] tempBuffer = new byte[m_maxDataSize];
         stream.skip( m_currPos );
         int bytesRead=stream.read( tempBuffer, 0, m_maxDataSize );
         System.out.println(" Read the following no of bytes from the Object::"+bytesRead);
         m_currPos+=     bytesRead;
    Please suggest what to do.

    Hi Shamish
    Actually you were on the right track, i think you just have to increase PSAPTEMP a bit and you will be fine. 358 MB seems just too small, i suggest you increase it to at least 2GB.
    1. what will be the difference in use of PSAPUNDO and PSAPTEMP while copy is running. ( i.e. what will be entered in PSAPUNDO and what will be filled in PSAPTEMP.)
    PSAPTEMP: is needed for large sort operations, as mentioned when you have a select with an ORDER BY clause, or if you do join two tables. During the client copy some sorting might be needed for special tables (cluster tables) where data is stored sorted.
    PSAPUNDO: undo space is only needed for DML (data manipulation), if data is changed undo is generated. This obviously is heavily the case during a client copy.
    2. the target client already has a copy taken 1 month before. so I think while importing it first delete existing data and then copies the new one.
    So If I first delete the target client and then take import on it; will it have advantage in regards of getiing UNDO or TEMP segments getting filled ?
    Deleting the client first might help for the undo problem, but you already solved that. I cannot imagine, it will help for the PSAPTEMP issue. As i said i would just increase PSAPTEMP and restart the copy.
    One more add: if you are doing the client copy with parallel processes, this will influence your requirements on temp and undo space, because of the concurrently running processes.
    Best regards
    Michael

  • Need Help Regarding Enabling The Matrix

    Hi All,
    We have got one user form and we have got one choose from list and one matrix, on click of choose from list the value will be displayed in the text box and at the same time matrix should get enabled. But it;s not happening in our case. The value is coming in the text box through choose from list but matrix is not getting enabled. We are able to change the back ground color of the matrix, make first column invisible and all but not able to enable the matrix. We need help regarding this one.
    Regards,
    Jayanth

    Hey first bind the columns of matrix to any user datasource
    and then you can enter any thing into your matrix 
    following code may help
    suppose you have one column
    oForm = SBO_Application.Forms.Item("URFRM")
    oUserDataSource = oForm.DataSources.UserDataSources.Add("URDSName",
    SAPbouiCOM.BoDataType.dt_SHORT_TEXT, 20)
    oMatrix=oForm.Item("URMATRX")
    oMatrix = oItem.Specific
    oColumns = oMatrix.Columns
    oColumn = oColumns.Item("URCOLName")
    oColumn.DataBind.SetBound(True, "", "URDSName")
    oMatrix.Addrow()
    hope this will help
    additionally you can look at this sample

  • I need help regarding measurement of "time domain parameters of Heart rate variability" using labview.

    I need help regarding measurement of "time domain parameters of Heart rate variability" using labview.
    I am using Labview 8 ... I  need to develop a software to accquire the ECG data (simulated enironment ) and compute the time domain parameters of Heart rate variability like "SDNN, SDANN...etc". Can some 1 plllzzzz help me out.Plzz help me if u can.Thanx in advance.

    Hi Andy,
      Thanx for responding.  The input is from a text file. SDNN, SDANN,etc are  the timedomain parameters of heart rate variability.
     SDNN: the standard deviation of the NN or RR interval  i.e. the square root of variance.
    SDANN:the standard deviation of the averageNN interval calculated over short periods, usually 5 min,which is an estimate of the changes in heart rate due tocycles longer than 5 min
    SDNN index, the meanof the 5-min standard deviation of the NN intervalcalculated over 24 h,
     RMSSD: the square root ofthe mean squared differences of successive NN intervals
    NN50: the number of interval differences of successiveNN intervals greater than 50 ms, and
    pNN50 the proportionderived by dividing NN50 by the total numberof NN intervals.
    The problem is dat I am a fresher to the world of Labview. I have jus recently started working on it. Can u please suggest me some some idea as soon as possible.
      As i said  I have the ECG data in the form of text files..I need to create sort of GUI to calculate the time domain parmeters....I need help urgently. Plzzz help me if u can. If u have and .vi example to calculate the RR interval plzz send it to me ASAP.
    Thanku

    Hey Seungly,
    I've realized that my computer runs fine UNLESS I turn the AirPort on to connect to the Internet. The moment I click "Turn AirPort On," the "You need to restart your computer" screen immediately pops up. Is there any connection between AirPort and my problem?
    That could very easily be the case, a bad Airport card. Look at this recent post:
