passing multiple values
I don't know if this is possible and it's difficult to explain. I have a form which shows a list of records from a table. Beside each record there is a checkbox. If the checkbox is checked it takes the value from the first field and passes it onto the next page. But what I want to do is when the box is checked I want to pass on the values from the first two fields as it's a combined primary and I'm using these values for a search condition where in delete sql statement. Here is the code for passing one value is it possible to pass two??
for (int i=0;i<v1.size();i++) { %> <tr><td><%=v1.get(i)%></td> <td><%=v2.get(i)%></td> <td><%=v3.get(i)%></td> <td><center><input type=checkbox name=delete value="<%=v1.get(i)%>"></td> </tr>

Tough question. There's really not enough info there to address it well, so forgive me if I missed your point.
It looks like you have declared (somewhere, at some point) a Vector v1. It also appears that this Vector contains form data and checkbox info that needs processing. Right so far? If I am correct, I'd suggest that you write a separate void class that accepts a Vector and pass v1 to this class: Code:
public void processV1(Vector v1){
synchronized(v1){
. . .
}
. . .
}
Another possibility: Code:
Vector v1 = parametersToVector(request.getParameterNames(), request);
public Vector parametersToVector(Enumeration enumeration, HttpServletRequest request){
Vector v = new Vector();
String param;
if(enumeration == null) return v;
// process Hashtable of parameters
while( enumeration.hasMoreElements() ) {
try{
param = enumeration.nextElement();
}
catch(NoSuchElementException nsee){}
. . .
}
}
Kind of awkward using the second way. It's a good idea to whisk the logic out of the page though. If I didn't answer you question, provide more detail.
