Hi :-)
* is the following right?
- StatesBean is your Helper class
- STATES_BEAN_NAME is a "public static String" object in StatesBean
if(the above is not right) return; //haha ^_^
* is StatesBean.STATES_BEAN_NAME.hashCode() the same one
before/after MyServlet reloading?
* and I suggest you try the following:
don't use StatesBean.STATES_BEAN_NAME as the "name" when you
setAttribute(...): i.e. I suggest you try:
- before reloading:
getServletContext().setAttribute( "haha", new StatesBean() );
- after reloading:
Object o = getServletContext().getAttribute( "haha");
try{
if(o!=null) StatesBean sb=(StatesBean)o;
}catch(Exception e){System.out.println(e);}
* can you post the code of your StatesBean? and
the version of TOMCAT? because I also want to
know why :-)
