Field Summary

protected java.lang.ClassLoader	classLoader The class loader to use for accessing our XML parser.
static boolean	validating

Constructor Summary

ParserUtils()

Method Summary

protected TreeNode	convert(TreeNode parent, org.w3c.dom.Node node) Create and return a TreeNode that corresponds to the specified Node, including processing all of the attributes and children nodes.
static ParserUtils	createParserUtils(java.lang.ClassLoader parentLoader) Create (if necessary) and return an instance of ParserUtils that has been loaded by our subordinate class loader (and therefore should have access to the XML parser that is visible to repositories of that class loader).
TreeNode	parseXMLDocument(java.lang.String uri, java.io.InputStream is) Parse the specified XML document, and return a TreeNode that corresponds to the root node of the document tree.
void	setClassLoader(java.lang.ClassLoader classLoader) Set the class loader used to access our XML parser.

Method Detail

parseXMLDocument

public TreeNode parseXMLDocument(java.lang.String uri,
                                 java.io.InputStream is)
                          throws JasperException

Parse the specified XML document, and return a TreeNode that corresponds to the root node of the document tree.

Parameters:

uri - URI of the XML document being parsed

is - Input stream containing the deployment descriptor

Throws:

JasperException - if an input/output error occurs

JasperException - if a parsing error occurs

setClassLoader

public void setClassLoader(java.lang.ClassLoader classLoader)

Set the class loader used to access our XML parser.

Parameters:

classLoader - The new class loader

convert

protected TreeNode convert(TreeNode parent,
                           org.w3c.dom.Node node)

Create and return a TreeNode that corresponds to the specified Node, including processing all of the attributes and children nodes.

Parameters:

parent - The parent TreeNode (if any) for the new TreeNode

node - The XML document Node to be converted

createParserUtils

public static ParserUtils createParserUtils(java.lang.ClassLoader parentLoader)

Create (if necessary) and return an instance of ParserUtils that has been loaded by our subordinate class loader (and therefore should have access to the XML parser that is visible to repositories of that class loader).

Parameters:

parentLoader - The web application class loader
