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
