Sorry couldn't resist this old chestnut :-) - even more efficient is:
String tables[]=req.getParameterValues("selectbox name");
StringBuffer createview = new StringBuffer();
for (int i = 0; i < tables.length-1; i++) {
createview.append(tables[i]);
createview.append(',');
}
createview.append(tables[tables.length-1]);
