Parameters:

schemaUrl - URL of the schema to parse

h - The hashtable to populate.

Throws:

findAndReadFile

public void findAndReadFile(java.lang.String filename,
                            java.util.HashMap<Tagpath,SchemaNode> h,
                            java.lang.Class clazz)
                     throws JNCException
