                          throws JasperException

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

Parameters:

location - Location (eg URI) of the XML document being parsed

is - Input source containing the deployment descriptor

Throws:

JasperException - if an input/output error occurs

JasperException - if a parsing error occurs

parseXMLDocument

public TreeNode parseXMLDocument(String uri,
                                 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

setEntityResolver

public static void setEntityResolver(EntityResolver er)

Set the EntityResolver. This is needed when the dtds and Jasper itself are in different classloaders (e.g. OSGi environment).

Parameters:

er - EntityResolver to use.

convert

protected TreeNode convert(TreeNode parent,
                           Node node)
