Use cases:
|
||
|
|
|
||
|
|
1. Simple dispatch
|
||
|
|
- servlet does startAsync()
|
||
|
|
- background thread calls ctx.dispatch()
|
||
|
|
<a href="<%=response.encodeURL("/examples/async/async0")%>"> Async 0 </a>
|
||
|
|
|
||
|
|
2. Simple dispatch
|
||
|
|
- servlet does startAsync()
|
||
|
|
- background thread calls dispatch(/path/to/jsp)
|
||
|
|
<a href="<%=response.encodeURL("/examples/async/async1")%>"> Async 1 </a>
|
||
|
|
|
||
|
|
3. Simple dispatch
|
||
|
|
- servlet does startAsync()
|
||
|
|
- background thread calls writes and calls complete()
|
||
|
|
<a href="<%=response.encodeURL("/examples/async/async2")%>"> Async 2 </a>
|
||
|
|
|
||
|
|
4. Simple dispatch
|
||
|
|
- servlet does a startAsync()
|
||
|
|
- servlet calls dispatch(/path/to/jsp)
|
||
|
|
- servlet calls complete()
|
||
|
|
<a href="<%=response.encodeURL("/examples/async/async3")%>"> Async 3 </a>
|
||
|
|
|
||
|
|
3. Timeout s1
|
||
|
|
- servlet does a startAsync()
|
||
|
|
- servlet does a setAsyncTimeout
|
||
|
|
- returns - waits for timeout to happen should return error page
|
||
|
|
|
||
|
|
4. Timeout s2
|
||
|
|
- servlet does a startAsync()
|
||
|
|
- servlet does a setAsyncTimeout
|
||
|
|
- servlet does a addAsyncListener
|
||
|
|
- returns - waits for timeout to happen and listener invoked
|
||
|
|
|
||
|
|
5. Dispatch to asyncSupported=false servlet
|
||
|
|
- servlet1 does a startAsync()
|
||
|
|
- servlet1 dispatches to dispatch(/servlet2)
|
||
|
|
- the container calls complete() after servlet2 is complete
|
||
|
|
- TODO
|
||
|
|
|
||
|
|
6. Chained dispatch
|
||
|
|
- servlet1 does a startAsync
|
||
|
|
- servlet1 does a dispatch to servlet2 (asyncsupported=true)
|
||
|
|
- servlet2 does a dispatch to servlet3 (asyncsupported=true)
|
||
|
|
- servlet3 does a dispatch to servlet4 (asyncsupported=false)
|
||
