Under WEB-INF/tags directory there is a file called select.tag.
I viewed the filed and found there are some lines of java codes wrapped within the

Code:

<%! %>:

<%!
...
try {
Object bean = jspContext.findAttribute(beanName);
Method m = bean.getClass().getMethod(methodName, null);
result = m.invoke(bean, null).toString();
...
%>

My question is: why use "!" after the

Code:

<%? Why not directly use <%.... %>>

Thanks.
