hi can u tell me how to use xml syntax with jsp
for example
<%="hello"%>
<%
int i=0;
%>
<% int i=0;%>
<% for(i=0;i<8;i++)
{%>
out.println(<%=i%>
;
<%
}
%>
<%="hello2"%>
gives the output
hello int i=0; out.println(0); out.println(1); out.println(2); out.println(3); out.println(4); out.println(5); out.println(6); out.println(7); hello2
but if i try with xml syntax
<jsp:expression>
"hello"
</jsp:expression>
<jsp:scriptlet>
int i=0;
</jsp:scriptlet>
<jsp:scriptlet> for(i=0;i<8;i++)
{</jsp:scriptlet>
out.println(<jsp:expression>i</jsp:expression> ;
<jsp:scriptlet>
}
</jsp:scriptlet>
it gives weird output
"hello" int i=0; for(i=0;i<8;i++) { out.println(i); }
how u r doing it with xml?
for example
<%="hello"%>
<%
int i=0;
%>
<% int i=0;%>
<% for(i=0;i<8;i++)
{%>
out.println(<%=i%>
;<%
}
%>
<%="hello2"%>
gives the output
hello int i=0; out.println(0); out.println(1); out.println(2); out.println(3); out.println(4); out.println(5); out.println(6); out.println(7); hello2
but if i try with xml syntax
<jsp:expression>
"hello"
</jsp:expression>
<jsp:scriptlet>
int i=0;
</jsp:scriptlet>
<jsp:scriptlet> for(i=0;i<8;i++)
{</jsp:scriptlet>
out.println(<jsp:expression>i</jsp:expression>
;<jsp:scriptlet>
}
</jsp:scriptlet>
it gives weird output
"hello" int i=0; for(i=0;i<8;i++) { out.println(i); }

Because the XML contained in it isn't well-formed -- it contains XML opening tags "html" and "body" without corresponding closing tags. By using a CDATA section you tell the HTML parser to treat the content as flat character data, not as XML.
If you are unsure about the concept of well-formedness I'd recommend you read a good XML tutorial; you won't properly understand JSP XML format unless you understand XML.

Yes you can, as this is well-formed XML.cant i just say
<jsp:text><title>asdasd<title></jsp:text>
