Here is a simplified overview of what you need to do. If you still would
like code, I can still supply you with it, but I think this will be easier
to understand.
ActionForm:
2 fields with associated getter and setters:
String[] CheckboxNames
String[] CheckboxValues
You must populate this form before you hit the JSP to display it (if you
want to preset the values). So, figure out all the possible values, and
then figure out what you want checked. So, for example...
checkboxNames[0] = "String1";
checkboxNames[1] = "String2";
checkboxNames[2] = "String3";
checkboxNames[3] = "String4";
and
checkboxValues[0] = "String2";
checkboxValues[1] = "String4";
Then say
MyForm form = new MyForm();
form.setCheckboxNames(checkboxNames);
form.setCheckboxValues(checkboxValues);
And put the form in the session.
When you get to your jsp, retreive the form from the session, and place it
into the page context:
pageContext.setAttribute("MyForm", myform , PageContext.PAGE_SCOPE);
Then, where you want the multiple checkboxes on your jsp, do the following:
<html:form name="MyForm" action="entry.do" type="com.mypackagemname.MyForm">
<TABLE border="1">
<logic:iterate name="MyForm" property="CheckboxNames" id="item1">
<TR>
<TD align="center">
<bean:write name="item1" />
</TD>
<TD align="center">
<html:multibox property="CheckboxValues">
<bean:write name="item1" />
</html:multibox>
</TD>
</TR>
</logic:iterate>
</TABLE>
<html:submit value="Save Changes"/>
<html:reset/>
</html:form>
THen when you press submit and go to your actionClass, you can compare
CheckboxNames to CHeckboxValues to see what was checked.
Did that explain it enough?
Hope it helps,
Becky
