download a file

[Edoardo Campagnano]

Hi to all,

here's the problem: I have a file in my DB as a byte[] array and i want a
link to permit the user to download the file. First, I'm able to ricreate a
disk-version of the file using FileOutputStream, the file is good (I can
open it on the server) but is generated on request thus i can't use it as an
asset in tapestry, how can I permit the user to obtain it?

 

Thanks a lot, Edoardo

Sorry for the other mail, this is the complete one

 

Hi,

I'm trying to compute a value at the moment my formi s submitted, in this
way

 

head

script type=text/javascript

  function getMessage() {

  document.myForm.myHidden.value=myComputedValue

  }

  /script

/head

body

form jwcid=[EMAIL PROTECTED]:AjaxForm onSubmit=javascript:getMessage();

  span jwcid=[EMAIL PROTECTED] value=ognl:myHiddenField/

submit jwcid=@tacos:AjaxSubmit
listener=listener:testMethod/

/form

/body

 

The idea i sto assign at submit time the value myComputedValue to the
hidden field and pass it to the server, but it doesn't work.

 

Any idea?

Accessing HiveMind Registry

[Edoardo Campagnano]

Hi to all,

I've got a small prioblem with HiveMind. I wrote a small Service but I must
use from a class taht is outside a Tapestry component and can't be declared
abstract. I need something like in the HiveMind manual:

 

(from the HiveMind home page)
.
Registry registry = RegistryBuilder.constructDefaultRegistry();
MyService service = (MyService)
registry.getService(com.mypackage.MyService, MyService.class);

.

 

The key is access the Registry but in this way it throws an exception. I'
don't know how but I'm sure it is possible

Problem with tacos:Grid component

[Edoardo Campagnano]

Hi,

I've been able to run the Tacos demos on my tomcat installation, then I try
to copy some elements in my Page components. Alol ok but the Grid. When it
reneders the copy of the demo, instead of renedering the rows as 

 

..

rows:[
{stringColumn:String
0,intColumn:0,floatColumn:0.0,dateColumn:2006-09-22},
{stringColumn:String
1,intColumn:10,floatColumn:100.5,dateColumn:2006-09-23},
{stringColumn:String
2,intColumn:20,floatColumn:200.7,dateColumn:2006-09-24},
{stringColumn:String
3,intColumn:30,floatColumn:300.75,dateColumn:2006-09-25},

...

 

(this is rendered in the demo application)

 

In my application it renders 

 

..

rows:[
{stringColumn:,intColumn:,floatColumn:,dateColumn:},
{stringColumn:,intColumn:,floatColumn:,dateColumn:},
{stringColumn:,intColumn:,floatColumn:,dateColumn:},
{stringColumn:,intColumn:,floatColumn:,dateColumn:},

..

 

As you can see, without the values. Verified that the List is well passed in
the java, I don't know why it doesn't work

Please help me, 

 

bye
