Hi Finally I got the answer for my own question.............
<html:image src="Images/Export.gif" styleClass="button" value="Export"property="export" />
<html:image src="Images/Search.gif" styleClass="button" value="Search" property="search" />
I am using above tags and if you want to check the values of this property you can check it by below code
if(request.getParameter("export.y") != null)
{
System.out.println(request.getParameter("export"));
objRptCaseDetailsExportBean.setStrBtnStatus("export");
strAction="export";
}else if(request.getParameter("search.x") != null){
objRptCaseDetailsExportBean.setStrBtnStatus("search");
strAction="search";
}
