RE:Form creation

[Stuart . Jameson]

Hi,

Got a  query about when ActionForm is created.

In struts config I map appname/MyQueries.do URL to MyQueryAction class via
struts config.  In execute method I expected the form to exist but it is
null (I haven't submitted the form yet I know but I thought the MyQueries.do
GET would act like I'd submitted the form).  

How do I force creation of the session scoped form? Do I have to set this up
myself first time I use it? I want to do this because I have select boxes
that have default values that the form knows about and I need to get these
default values out of the form in order to run my query the 1st time.

Am I making an complete architectural howler by wanting a form to exist so I
can set up the page before I use it?  

TIA

Stu

Not sure that the algorithm 'randomly' calculates the date but here you

RE:options

[Stuart Jameson]

Having trouble using

I have a container, MyTypesList to store a list of MyType beans

beanList contains the following.

private Vector myTypes;  (of type MyType)

MyBean has properties  ID and typeName.

I'm trying to output a select box that displays the possible typeNames and submits the 
value of ID in order to populate the typeID property of another bean.  

I don't quite understand how to reference the properites in the bean in my list.
I seem to have to do the following








 
** How do I reference the properties in myTypes from here?

Thanx  Stu

RE: File upload

[Stuart Jameson]

Thanks Rob,

Problem was I hadn't found the struts docs for FormFile. 

  public void setMyFile(FormFile file) {
myFile = file;
  }
  public FormFile getMyFile() {
return myFile;
  }

 Struts deals with file upload for you.  Suspected it might but I didn;t rtfm 
sufficiently before posting a question.

Try flushing the buffer before closing.

pw.flush();

or create the PrintWriter using the output stream and the autoflush flag set
to true.

PrintWriter pw = new PrintWriter(new BufferedWriter( new
FileWriter("C:\\Demo.out"), true);

HTH,

robert

RE: File upload

[Stuart Jameson]

Hi,

Got a problem with uploading files to the server.

I don't get any errors but the files I try and upload are always empty

Code I'm using in the Action::perform() method looks like this



PrintWriter pw = new PrintWriter(

new BufferedWriter( new FileWriter("C:\\Demo.out") ) ); 
int i = in.read();
while (i != -1) {
pw.print((char) i);
i = in.read();
}
pw.close();


Demo.out is created but empty.

Any pointers of what I need to add to my jsp page or to my Action servlet greatly 
appreciateed.

losing checkbox info between pages

[Stuart Jameson]

Hi,

I have 1 form split over 2 pages.  Page 1 has a checkboxA page 2 has checkboxB

Unless I put a hidden field A in page 2 and a hidden field B in page 1 the checkboxes 
aren't set correctly (because reset() is called each the page is submitted).  

I assume there is a better way to do this.  Anyone tell me how I should write it so 
that HTML people can just move the checkboxes between pages without having to worry 
about moving a hidden field as well?

Hope someone can enlighten me,
