Netui:Checkboxoption, set checked without javascript

Question

I am working on weblogic 8 portal and attempting to set the checkboxoption to checked when the page initially renders with the following code with style=(quotes) checked:true (quotes), sorry if i'm typing (quotes) since it's emptying it out on the forum.
<netui:checkBoxGroup dataSource="{pageFlow.displayDocuments}">
<%
if (pageContext.getAttribute("isDocumentExposedToInternet").toString().equalsIgnoreCase("true")) {
%>
<netui:checkBoxOption value="{container.index}" tagId="chkBox" style=(quotes) checked:true (quotes) onClick="setRdoValue(this)">TRUE</netui:checkBoxOption>
<%
} else {
%>
<netui:checkBoxOption value="{container.index}" tagId="chkBox" style=(quotes) checked:true (quotes) onClick="setRdoValue(this)">FALSE</netui:checkBoxOption>
<%
%>
</netui:checkBoxGroup>
does anyone know if this is the only way to set the checkbox value? I can't really do it with javascript since i need an onclick event to access it and i need this to be checked when the page initially renders.
thanks in advance.

Hi
This is the code snippet I have that is working fine and checking the check boxes values properly.
<netui:checkBoxGroup dataSource="actionForm.credTechHighFreq" orientation="vertical">
     <c:forEach items="${sessionScope.GRACE_LOOKUPS['Credential_High Frequency']}" var="eachHighFreq">
          <%-- workshop:varType="com.hid.iod.forms.IoDLookUpForm" --%>
               <netui:checkBoxOption value="${eachHighFreq.iodLookUpId}">${eachHighFreq.codeDescription}</netui:checkBoxOption>
     </c:forEach>     
</netui:checkBoxGroup>
In above code sniippet, I have actionForm.credTechHighFreq that stores the IDs of the selected checkbox. I can check multiple checkboxes. this is the variable I have in my Form class.
private long[] credTechHighFreq;
The checkboxOptions are retrieved from a session variable, which is kind of lookup value which has like Id and Desc. Desc is what I show on screen. Id is the one behind the screens.
So when I retireve this data and open the page for the very first time, if my datasource [] is having say like 1, 3, 5, these 3 checkboxes are checked.
NOW if you want to have default values, then you need to fill the datasource [] list say with like 1, 3. So these are like default. Do this only if the list is empty. Infact I do this by adding alwasy [0] and the value wil lbe like "Please Select".
For CheckBox or RadioButton, or SelectBoxes, always there will be like a Key/Value Pair. Like what we see next to checkbox and when we checkit or uncheckit, the datasource that is behind this visible value. Using style attribute is not the right way and may not work also. style attribute is used only for css stuff like for look and feel stuff only. You are iterating through "pageFlow.displayDocuments" and what is the object like datatype for each of these objects. Those should have like key/value paris.
Inside a checkboxgroup, when we check any Checkbox (for now lets assume we can check only one), then the checked behind id value is what stored in the datasource attribute for checkBoxGroup. Incase if you can check multiple checkboxes, then the datasource will be Array/List of selected items.
Incase if you can check only one option like True or False, instead of CheckBox use Radio Button.
