Added wrapping for Throwables to avoid ClassCastException: see Bugzilla 31171 for details. The Exception associated with this page context, if any. getExpressionEvaluator public ExpressionEvaluator getExpressionEvaluator()(Code) Provides programmatic access to the ExpressionEvaluator. The JSP Container must return a valid instance of an ExpressionEvaluator that can parse EL expressions. getOut public JspWriter getOut()(Code) getPage public Object getPage()(Code) getRequest public ServletRequest getRequest()(Code) getResponse public ServletResponse getResponse()(Code) getServlet public Servlet getServlet()(Code) getServletConfig public ServletConfig getServletConfig()(Code) getServletContext public ServletContext getServletContext()(Code) getSession public HttpSession getSession()(Code) getVariableResolver public VariableResolver getVariableResolver()(Code) handlePageException public void handlePageException(Exception ex) throws IOException, ServletException(Code) handlePageException public void handlePageException(Throwable t) throws IOException, ServletException(Code) include public void include(String relativeUrlPath) throws ServletException, IOException(Code) include public void include(String relativeUrlPath, boolean flush) throws ServletException, IOException(Code) initialize public void initialize(Servlet servlet, ServletRequest request, ServletResponse response, String errorPageURL, boolean needsSession, int bufferSize, boolean autoFlush) throws IOException(Code) popBody public JspWriter popBody()(Code) proprietaryEvaluate public static Object proprietaryEvaluate(String expression, Class expectedType, PageContext pageContext, ProtectedFunctionMapper functionMap, boolean escape) throws ELException(Code) Proprietary method to evaluate EL expressions. XXX - This method should go away once the EL interpreter moves out of JSTL and into its own project. For now, this is necessary because the standard machinery is too slow. Parameters:   expression - The expression to be evaluated Parameters:   expectedType - The expected resulting type Parameters:   pageContext - The page context Parameters:   functionMap - Maps prefix and name to Method The result of the evaluation pushBody public BodyContent pushBody()(Code) pushBody public JspWriter pushBody(Writer writer)(Code) release public void release()(Code) removeAttribute public void removeAttribute(String name, int scope)(Code) removeAttribute public void removeAttribute(String name)(Code) setAttribute public void setAttribute(String name, Object attribute)(Code) setAttribute public void setAttribute(String name, Object o, int scope)(Code) Fields inherited from javax.servlet.jsp.PageContext final public static String APPLICATION(Code)(Java Doc) final public static int APPLICATION_SCOPE(Code)(Java Doc) final public static String CONFIG(Code)(Java Doc) final public static String EXCEPTION(Code)(Java Doc) final public static String OUT(Code)(Java Doc) final public static String PAGE(Code)(Java Doc) final public static String PAGECONTEXT(Code)(Java Doc) final public static int PAGE_SCOPE(Code)(Java Doc) final public static String REQUEST(Code)(Java Doc) final public static int REQUEST_SCOPE(Code)(Java Doc) final public static String RESPONSE(Code)(Java Doc) final public static String SESSION(Code)(Java Doc) final public static int SESSION_SCOPE(Code)(Java Doc) Methods inherited from javax.servlet.jsp.PageContext abstract public void forward(String relativeUrlPath) throws ServletException, IOException(Code)(Java Doc) public ErrorData getErrorData()(Code)(Java Doc) abstract public Exception getException()(Code)(Java Doc) abstract public Object getPage()(Code)(Java Doc) abstract public ServletRequest getRequest()(Code)(Java Doc) abstract public ServletResponse getResponse()(Code)(Java Doc) abstract public ServletConfig getServletConfig()(Code)(Java Doc) abstract public ServletContext getServletContext()(Code)(Java Doc) abstract public HttpSession getSession()(Code)(Java Doc) abstract public void handlePageException(Exception e) throws ServletException, IOException(Code)(Java Doc) abstract public void handlePageException(Throwable t) throws ServletException, IOException(Code)(Java Doc) abstract public void include(String relativeUrlPath) throws ServletException, IOException(Code)(Java Doc) abstract public void include(String relativeUrlPath, boolean flush) throws ServletException, IOException(Code)(Java Doc) abstract public void initialize(Servlet servlet, ServletRequest request, ServletResponse response, String errorPageURL, boolean needsSession, int bufferSize, boolean autoFlush) throws IOException, IllegalStateException, IllegalArgumentException(Code)(Java Doc) public BodyContent pushBody()(Code)(Java Doc) abstract public void release()(Code)(Java Doc)
