Hi,
Replace your getParameterValues("proField" ) with
"request.getParameterValues("proField" )".

Subject: 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
