Try this :
TestBean bean = new TestBean();
Digester digester = new Digester();
digester.setValidating(false);
digester.push(bean);
digester.addObjectCreate("toplevel/element/");
digester.addCallMethod("toplevel/element/field1", "setField1", 0);
digester.addCallMethod("toplevel/element/field2", "setField2", 0);
digester.parse (blah);
and you have a nice bean (mind the ending / on addObjectCreate.
Probably betwixt will serve a better needs for your needs and (can be)
simpeler (check it out from cvs, and look at the testcases for
examples..)
