jsp useBean tag

+Pie Number of slices to send: Send
hi
iam having a problem with jsp useBean tag.
is the synax <jsp:useBean.. >
</jsp:useBean>
or just <jsp:useBean.... />
i mean which is the correct way of closing
and also is it compulsory to put all set and get propery tags
between the opening and closing useBean tags.
recently when iam trying with jrun it gave me an error when iam
trying to instantiate a bean class through this tag. i've kept the jsp file in the default web application directory and the class file in web-inf/clases folder.
the following is the error iam getting
500 Internal Server Error

Either syntax should work. The syntax I normally use is:
<jsp:useBean class="FooBean" id="foo" scope="session">
</jsp:useBean>
However, the other syntax will also work:
<jsp:useBean class="FooBean" id="foo" scope="session" />
As far as the set and get property tags, put them between
the useBean tags if you want them to execute only when the
bean is first instantiated. If the bean is reused, either
on that page or another one, any set or get property tags
will be ignored. For good general info on useBean, go to:

It's hard to be sure what's causing your error without seeing
the line of code it referenced. My guess it that you have a
declaration statement without a semi-colon at the end:
<%! int i=0 %> instead of <%! int i=0; %>
