unwinding the stack
org.apache.jasper.runtime.PageContextImpl private void _initialize(Servlet
servlet, ServletRequest request,
127 ServletResponse response, String errorPageURL,
128 boolean needsSession, int bufferSize, boolean
autoFlush)
129 throws IOException {
.......
143 if (request instanceof HttpServletRequest && needsSession)
144 this.session = ((HttpServletRequest)
request).getSession();
145 if (needsSession && session == null)
146 throw new IllegalStateException(
147 "Page needs a session and none
is available");
which is called by org.apache.jasper.runtime.JspFactoryImpl
internalGetPageContext
89 private PageContext internalGetPageContext(Servlet servlet,
ServletRequest request,
90 ServletResponse response, String errorPageURL, boolean
needsSession,
91 int bufferSize, boolean autoflush) {
92 try {
93 PageContext pc;
94 if (USE_POOL) {
95 PageContextPool pool = localPool.get();
96 if (pool == null) {
97 pool = new PageContextPool();
98 localPool.set(pool);
99 }
100 pc = pool.get();
101 if (pc == null) {
102 pc = new PageContextImpl();
103 }
104 } else {
105 pc = new PageContextImpl();
106 }
107 pc.initialize(servlet, request, response, errorPageURL,
108 needsSession, bufferSize, autoflush);
internalGetPageContext is referenced in the run method as shown
148 public Object run() {
149 return factory.internalGetPageContext(servlet, request,
response,
150 errorPageURL, needsSession, bufferSize, autoflush);
151 }
but none of this *should happen if the jsp execution did'nt double submit*
