<%@ page import yourjavafile.java%>
<%
Test str_test = new Test();
String query1="select name from usermaster";
str_test.queryset(query1);
out.println("query has been set");
%>

Subject: Re: bean and jsp question
If you want to use the useBean tag, your constructor should NOT have
argument.
That's a part of the beans definition.... Of course you could find a
workaround.
<jsp:useBean id="toto" class"..." scope="..." >
<% toto.init(arg1, arg2); %>
</jsp:useBean>
The code between <jsp:useBean..> and </jsp:useBean> is only executed
when the
instance is created ....
Hope this help
