1. 解析，jsp页面之后将整个jsp页面存放到的数据结构中

  public static class Nodes {

        private List list;

        private Node.Root root; // null if this is not a page

        private boolean generatedInBuffer;

        public Nodes() {
            list = new Vector();
        }

        public Nodes(Node.Root root) {
            this.root = root;
            list = new Vector();
            list.add(root);
        }

        /**
         * Appends a node to the list
         * 
         * @param n
         *            The node to add
         */
        public void add(Node n) {
            list.add(n);
            root = null;
        }

        /**
         * Removes the given node from the list.
         * 
         * @param n
         *            The node to be removed
         */
        public void remove(Node n) {
            list.remove(n);
        }

        /**
         * Visit the nodes in the list with the supplied visitor
         * 
         * @param v
         *            The visitor used
         */
        public void visit(Visitor v) throws JasperException {
            Iterator iter = list.iterator();
            while (iter.hasNext()) {
                Node n = (Node) iter.next();
                n.accept(v);
            }
        }

        public int size() {
            return list.size();
        }

        public Node getNode(int index) {
            Node n = null;
            try {
                n = (Node) list.get(index);
            } catch (ArrayIndexOutOfBoundsException e) {
            }
            return n;
        }

        public Node.Root getRoot() {
            return root;
        }

        public boolean isGeneratedInBuffer() {
            return generatedInBuffer;
        }

        public void setGeneratedInBuffer(boolean g) {
            generatedInBuffer = g;
        }
    }

jsp文件是否是可以存放在jar文件中呢？从下面的这段代码中貌似是可以的

public URL getResource(String res) throws MalformedURLException {
        URL result = null;

        if (res.startsWith("/META-INF/")) {
            // This is a tag file packaged in a jar that is being compiled
            URL jarUrl = tagFileJarUrls.get(res);
            if (jarUrl == null) {
                jarUrl = tagFileJarUrl;
            }
            if (jarUrl != null) {
                result = new URL(jarUrl.toExternalForm() + res.substring(1));
            }
        } else if (res.startsWith("jar:file:")) {
                // This is a tag file packaged in a jar that is being checked
                // for a dependency
                result = new URL(res);

        } else {
            result = context.getResource(canonicalURI(res));
        }
        return result;
    }
