hi,
ur Action class is correct. may be the problem is with ur struts-configuration.xml file.
u given tha,
if( (admnName.equals(admn)) && (admnPwd.equals(pwd)))
{
request.setAttribute("kk",admnName);
forward = mapping.findForward("view");
}
else
{
forward = mapping.findForward("index");
}
return(forward);
And check ur struts-config.xml entry should match with this,
<action-mappings>
<action path="/xxx" type="xxx">
<forward name="view" path="/ur path/view.jsp" />
<forward name="index" path="/ur path/index.jsp" />
</action>
</action-mappings>
Normal Jsp page we send this procedure :
admincheck.jsp:
<% if( (admnName != admn) && (admnPwd !=pwd )) {%>
<jsp:forward page="index.jsp">
<jsp:param name="errMsg"
value="Sorry Your UserName and Password is Mismatch" />
</jsp:forward>
<% } %>
index.jsp
<%
String error = request.getParameter("errMsg");
if(error != null)
out.println("
<font color=FF0000 size = 3>" + error + "</font>
");
%>
In Struts How to send error message.Will you help me what is the procedure .
if( (admnName.equals(admn)) && (admnPwd.equals(pwd)))
{
request.setAttribute("kk",admnName);
return(mapping.findForward("view"));
}
else
{
return(mapping.findForward("index"));
}
Please help me.
hi,
if u want to send the static error message, u can send it through the StrutsConfig.xml file.
else
{
return(mapping.findForward("index"));
}
In forward statement use this syntax,,
<actionmappings>
<action name="" path="">
<foward name="index" path="/Index.jsp?errMsg=Sorry your UserName and Password is Mismatch" />
</action>
</actionmappings>
In other way, if u want to send the dynamic error msg,
else
{
request.setAttribute("errMsg", " ur msg");
return(mapping.findForward("index"));
}
these two ways will work.

pavan.
