JSP:Datatags

Question

i have 2 questions:
1)
i have a query which returns rows with three attributes.However the number of rows it returns may vary.
i want to display these rows in a table.the table is dynamic(cos i dont know how many rows the query will return),hence i want a table which will scroll automatically as the rows increase.this table has to be editable.
how can i achieve all this ,either using data tags or html table.
2) i want to provide combo boxes using inputselect datatag,however this tag does not allow to show default value.i want the combo box to be bound to the databse,so that i can just say update/insert in my submit.jsp page.
please help

Hi here is the solution for your question # 2:
Step 1:
create a dynamic view object which returns the set of values for the list.
<jbo:CreateViewObject appid="<%= sPool %>" name="CgRefCodesView1" >
SELECT RV_LOW_VALUE AS RV_LOW_VALUE FROM CG_REF_CODES WHERE RV_DOMAIN = 'YESNO' ORDER BY 1 DESC
</jbo:CreateViewObject>
<jbo:DataSource id="DS_Lookup_Type1" appid="<%= sPool %>" viewobject="CgRefCodesView1" ></jbo:DataSource>
Step 2: Get the original value into a variable. And Declare HTML select input type.
By using rowset iterator every time compare the datasource value(declared in dynamic view object) with the original value. If matched say selected. please follow the code
below.If you find any problems I will explain
in detail.
<%
String myVar = (String) DS_Master.getRowSet().getCurrentRow().getAttribute("XenograftFlag");
%>
// or you can assign default value to myVar in the above code
<SELECT name="XenograftFlag" >
<jbo:RowsetIterate datasource="DS_Lookup_Type1">
<%
myVar1 = (String) DS_Lookup_Type1.getRowSet().getCurrentRow().getAttribute("RV_LOW_VALUE");
try {
if (myVar.equals(myVar1)) {
%>
<OPTION SELECTED><jbo:ShowValue datasource="DS_Lookup_Type1" dataitem="RV_LOW_VALUE" />
<% }else { %>
<OPTION><jbo:ShowValue datasource="DS_Lookup_Type1" dataitem="RV_LOW_VALUE" />
<% }} catch(Exception e) {
%>
<OPTION><jbo:ShowValue datasource="DS_Lookup_Type1" dataitem="RV_LOW_VALUE" />
<% } %>
</jbo:RowsetIterate>
<%
try {
if (myVar.equals("")) {
%>
<OPTION SELECTED>
<% }else { %>
<OPTION>
<% }} catch(Exception e) {
%>
<OPTION SELECTED>
<% } %>
</SELECT>
