Unable to send the full value of the action class to jsp

Hello

I have the script as,

In my class action.

DemoAction.java
int samplevar = 3;

Add to the string since the application only accepts objects.

The example of string = "" + samplevar ".

request.setAttribute ("sampleVar", model);

Demo.jsp

< % int demovar = Integer.parseInt (request.getAttribute ("sampleVar")); % >

But I can't get the value... what could be the reason please help...

Welcome to the forum.

You should better stick with one type of the number object:
Whole sample = new Integer (samplevar);
or leave conversion autoboxing (java 1.5 +)
Whole sample = samplevar;

request.setAttribute ("sampleVar", model);

You must put in the answer, and not in the application...
response.setAttribute ("sampleVar", model);

>

Demo.jsp

<% int demovar = Integer.parseInt(request.getAttribute("sampleVar")) ; %>

<%-- when passing an Integer object this changes to: --%>
<% int demovar = ((Integer)request.getAttribute("sampleVar")).intValue(); %>

Good bye

    Unable to send the message from my account to my other in Outlook Express 6

    What is a Pop3 account? IMAP? Hotmail? Can I assume that it used to work? If it worked until recently, follow these steps.
     
     
    Spend most of your messages out of the Inbox and then create new folders to send and sent items box after having moved the messages you want to save to a local folder that you create.
     
    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.
     
    In Windows XP, the files of user OE (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.
     
    With OE closed, find the DBX files for the items in the Outbox and sent and delete them.  New ones will be created automatically when you open OE.
     
    After you're done, followed by compacting your folders manually while working * off * and do it often.
     
    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.
     
    General precautions for Outlook Express:
     
    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

  • Unable to send the form without attachment if file upload fails

    Hi all

    I have a form, in which I have a component of the input file.

    Scenario 1 - if I do not attach and submit the form, it is successful.

    Scenario 2 - if I attach a file of size less than 2 MB and then submit, it is successful.

    Scenario 3 - if I attach a file of size greater than 2 MB and then submit, ADF gives an error message saying "the file is large" that is expected.

    3.1 - in scenario 3, after the failure of downloading files, I want to send the form without attaching any file. But the form is not filed and the warning message still appears.

  • Unable to get the Service class

    I did a few test installs workspace as assessment locations.

    Whenever I try to buried in the central offices of data service to make changes, I may enter only once and then from there, there is no way to show, edit or copy the default COS value; all I get is the error above.

    This is a new installation, following the manual and most of the default settings, including ssl certificates. only, I joined the domian and configured the device connector to collect thinapp packages.

    Everything works fine and I have had no error installation and configuration of vApp.

    I tried to put this device into maintenance mode and discount online and also rebooted it but no luck.

    Someone at - it had the same problem? Is there a way around it?

    Thank you!

    I sent the following to you as a private on 20 June message e-mail, did you receive it? I now obscured the real email address.

    Hello

    Thank you for sending the detailed log. After watching the token, it seems that there may be two user records using the same email id-

    We do not support two users having the same email address. It is possible the user you are connected to the workspace horizon, providing data breach, as is an e-mail duplicate. Therefore, you are not able to access the COS.

    Can you change the email address and the new provision? Or remove the other user?

  • TCP Comm send the Hex data

    I have an embedded device server that has a controllable set of 8 pins of the user. The format of order for these pieces requires a TCP message which is 9 bytes long and hexadecimal.

    I use TCP Communicator - Active .VI in the LV7.1 examples, make a link to the server of the device. There is no problem with the connection - but I'm unable to send the message in HEX format.

    The transmitter/receiver always converts my entry into ASCII and the command fails so. Also, he fragments the typed command bytes and when I probe the resultng with a network Analyzer (Ethereal) data package I see that the VI has fragmented the bytes of data in several discrete packages.

    The order message I want to send is in this format: FF 00 00 00 FF 00 00 00 1B

    Any suggestions to solve the problem?

    Thank you

    You must either create your string in hexadecimal display mode so that you know that you enter hexadecimal values, rather than characters, or use a byte array, and then use the function to the array of bytes to a string . I would opt for the latter because it is easier to understand.

    Note that the table is an array of integers of U8 whose formatting the hexadecimal value, and using a field width minimum 2 characters, zeros on the left and with the radix displayed. Makes it more clear that this is a hexadecimal value.

  • I'm unable to send emails from my Outlook

    Everything worked ok, for centuries. All of a sudden I'm emails send unable o of my Outlook.

    "The message I get is:"unable to send the message. " Please check the e-mail address of your account properties.

    When I "send a Test Message" from Outlook, tools, accounts. All actions are completed in addition to sending a test message when I get also the statement.

    Hello

    If it happened all of a sudden, so maybe it was a virus?
    I put t know why you're not able to send emails.
    I think that you should check the properties of the e-mail account. Check the data you POP3 and SMTP server.
    I m not an expert in Outlook, but this option should be somewhere in the email account properties.

    The last option would be to remove the e-mail account in outlook, then a new creation of the new account.
