Hi Seshu,
Rather than coding in the CO, create a method in AM and then call the method in the CO. I will give you sample code to handle this requirement.
add this in processFormRequest method of CO where you are setting the actions of Create and Cancel buttons.
if( pageContext.getParameter("Clear")!=null)
          am.clearForm(pageContext, webBean);
And in AM,
public void clearForm(OAPageContext pageContext, OAWebBean webBean)
     SiteDetailsVOImpl vo = getSiteDetailsVO();
OAMessageTextInputBean Item1_nameBean = ( OAMessageTextInputBean )
webBean.findChildRecursive("Item1_name ");
     Item1_nameBean.setValue(pageContext, null );
     OAMessageLovInputBean Item2_nameBean =( OAMessageLovInputBean )
webBean.findChildRecursive("Item2_name");
     Item2_nameBean.setValue(pageContext,null );
     vo.setWhereClauseParam(0,"####"); // here # is a junk char to make the condition as false
     vo.setWhereClauseParam(1,"####");
vo.executeQuery();
As we are passing the Junk values in setWhereClauseParam, and the condition go false, the form should be cleared.
Check with the above information and post the outcome.
