[jboss-user] [Beginners Corner] - Digester problem...ClassNotFoundException
Hi all,
I have a problem using the class com.sun.org.apache.commons.digester.Digester:
| public class HibernateConfig {
| private String name;
|
| public String getName() {
| return name;
| }
|
| public void setName(String name) {
| this.name = name;
| }
| }
And this method in another class
| public Configuration digest() throws MappingException, ClassNotFoundException,
IOException, SAXException {
| Digester digester = new Digester();
|
| digester.push(this);
|
| digester.addObjectCreate("classes/class",
br.com.ze.configuration.HibernateConfig.class);
| digester.addBeanPropertySetter("classes/class/name");
|
| digester.addSetNext("classes/class", "addClass");
|
| HibernateConfigurationApplier hconf = null;
| if(xmlClassesConfigFile != null)
| hconf = (HibernateConfigurationApplier) digester.parse(xmlClassesConfigFile);
| else
| hconf = (HibernateConfigurationApplier)
digester.parse(xmlClassesConfigInputStream);
|
| Configuration configuration = new Configuration();
|
| for(HibernateConfig clazz: hconf.classes)
| configuration.addClass( Class.forName(clazz.getName()) );
|
| return configuration.configure();
| }
|
And the following XML file:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <classes>
| <class>
| <name>br.com.ze.common.model.Banco</name>
| </class>
| <class>
| <name>br.com.ze.common.model.Contrato</name>
| </class>
| <class>
| <name>br.com.ze.common.model.Produto</name>
| </class>
| <class>
| <name>br.com.ze.common.model.Segmento</name>
| </class>
| </classes>
|
When I execute the following:
| public static void main(String[] args) throws MappingException, FileNotFoundException,
ClassNotFoundException, IOException, SAXException {
| Configuration conf = new
HibernateConfigurationApplier("WebContent/WEB-INF/persistent-classes.xml").digest();
| }
|
It runs just fine, but when I execute the same line in a javax.servlet.Filter Iôve
done:
| public void init(FilterConfig filterConfig) throws ServletException {
| Configuration config;
| try {
| config = new
HibernateConfigurationApplier(filterConfig.getServletContext().getResourceAsStream("WEB-INF/persistent-classes.xml")).digest();
| } catch (Exception e) {
| throw new ServletException(e);
| }
| }
|
I get this exception:

The exception is thrown at digester.parse()
Iôm using Eclipse Europa, JAVA 6 and JBOSS 4.2.2
Any help??!?!?!
Thanks in advance.
