Good morning,
I work with Tomcat4.0.3 e windows NT 4.0.
I installed in common/lib these jar: commons-beanutils.jar (v. 1.5),
commons-collections.jar (v. 2.1), commons-logging.jar (v. 1.0.2) and
commons-digester.jar (v. 1.3).
Inside my servlet I coded like this:
============================================
Digester digester = new Digester();
digester.setValidating(false);
digester.addObjectCreate("region","it.tosca.util.Region");
digester.addObjectCreate("region/city","it.tosca.util.City");
digester.addBeanPropertySetter("region/city/code","code");
digester.addBeanPropertySetter("region/city/area","area");
digester.addBeanPropertySetter("region/city/description","description");
digester.addBeanPropertySetter("region/city/address","address");
digester.addBeanPropertySetter("region/city/telephone","telephone");
digester.addBeanPropertySetter("region/city/fax","fax");
digester.addBeanPropertySetter("region/city/email","email");
digester.addSetNext("region/city","addCity");
File file = new
File("/home/Sil/SilXML/info_region.xml");
Region li = (Region)digester.parse(file);
System.out.println(li.toString());
=============================================================
At runtime I caugth this error:
10 [HttpProcessor[8080][4]] ERROR digester.Digester - Begin event threw
exception
java.lang.ClassNotFoundException: it.tosca.util.Region

I solved this problem by moving commons-digester.jar from common/lib to
webapps/Sil/WEB-INF/classes and unzip the jar in last directory.
I think it was a Class loader problem. Is there a way for success leaving
commons-digester.jar in common/lib?
Do I have to use another class loader type? How can I set it?
Can you help me?
Best regards,
Simone Nannetti
