i found this class a while ago on this list it works great, just create a
parameter action forward and then add
params
forward.addParameter("name", "value");
return forward;
import java.util.HashMap;
import java.util.Iterator;
public final class ParameterActionForward extends ActionForward {
private static final String questionMark = "?";
private static final String ampersand = "&";
private static final String equals = "=";
private HashMap parameters = new HashMap();
private String path;
public ParameterActionForward(ActionForward forward) {
setName(forward.getName());
setPath(forward.getPath());
setRedirect(forward.getRedirect());
}
public void setPath(String path) {
this.path = path;
}
public String getPath() {
StringBuffer sb = new StringBuffer();
sb.append(path);
boolean firstTimeThrough = true;
if (parameters != null && !parameters.isEmpty()) {
sb.append(questionMark);
Iterator it = parameters.keySet()
.iterator();
while (it.hasNext()) {
String paramName = (String)it.next();
String paramValue = (String)parameters.get(paramName);
if (firstTimeThrough) {
firstTimeThrough = false;
} else {
sb.append(ampersand);
}
sb.append(paramName);
sb.append(equals);
sb.append(paramValue);
}
}
return sb.toString();
}
public void addParameter(String paramName, Object paramValue) {
addParameter(
paramName,
paramValue.toString());
}
public void addParameter(String paramName, String paramValue) {
parameters.put(paramName, paramValue);
}
}
