Re: how to pipe values from select-Tag ?

Hi there ( if there is still anybody :-)),

well,
what the hell is going wrong with my <select>-value. Shame on me but i don't get it.

///////////////////////////////////////////////////////////////////////
                out.println("<center>"
    
        +"<select name=\"proField\" "
        +"<option><---------------------------------------------------></option>");
        for(i = 1; i<length;i=i+2)
        {	
                out.println("<option value=\""+vec.get(i)+"\">"+vec.get(i)+"</option>");
   
        }
        out.println("</select>");
                i=0;


out.print("<br><br><br><br><br><br>"+
	
"<table>"+
"<colgroup><col><col width=\"0%\" span=\"4\"></colgroup>"+
"<tr>"+
"<td>"+
"<FORM ACTION = \"http://10.48.229.45/examples/servlet/Select\" METHOD = \"GET\">"+
"<input type = \"submit\" name=\"edit\" value = \" edit\" height=\"20\" width=\"10\">"+
"<input type=\"hidden\" name=\"alias\" value=\""+alias+"\" >");
"........................................................................................................"
out.println("</form>"+
"</td>"+
"<td>"+
........

///////////////////////////////////////////////////////////////////////////////////////////////////////

in line"..............................................................................................." i would place a hidden textfield with the content of the selected item in "proField".
Then I transfer data by triggering the button to a Class(here:Selected) that receives data in doGet(...) Method. So far so good. But if I want to have the selected Item I got problems.
getParameterValues("proField") should return a String []. Ok. But the Array is null :-( ?

I got a Method for it :
                
                 private String getFile()
        {
                String[] pfad = getParameterValues("proField" );
                return pfad[0];
        }
 
and i call it like that : 

"<ínput type=\"hidden\" name=\"file\" value=\""+getFile()+"\">");

( this is the hidden Textfield  with the content of the returned String....

There's errormessage :

               C:\ServletDevel\WebExcel\CheckLoginMod.java:127: cannot resolve symbol
                   symbol  : method getParameterValues (java.lang.String)
                   location: class CheckLoginMod
        String[] pfad = getParameterValues("proField" );
                                ^


Please Help.

Thx 

Bastian
