Hello,
it seems that the Digester Class of Struts is a strange thing.
I take the following XML-Document (in a String):
<?xml version="1.0" encoding="UTF-8"?>
<login usr="Benutzername"
hilfe="true"
rn="Hartmut Bernecker"
mail="[EMAIL PROTECTED]"
txt="Persoenlicher Begruessungstext des Benutzers"
spr="de"
med="medium">
<grp name="Gruppe 1" txt="Begruessungstext 1"></grp>
<grp name="Gruppe 2" txt="Begruessungstext 2"></grp>
</login>
------------------------------------------------------------------
Then I want to parse it with a Digester object as follows:
------------------------------------------------------------------
Digester digester = new Digester();
digester.setDebug(1);
digester.setValidating(false);
digester.push(this);
digester.addObjectCreate("login/grp",
"de.dhw.asim.components.benutzer.BenutzerGruppe");
digester.addSetProperties("login/grp");
digester.addSetNext("login/grp", "addGrp",
"de.dhw.asim.components.benutzer.BenutzerGruppe");
digester.addObjectCreate("login",
"de.dhw.asim.components.benutzer.LoginObjekt");
digester.addSetProperties("login");
digester.addSetNext("login", "setLoginObjekt",
"de.dhw.asim.components.benutzer.LoginObjekt");
try {
digester.parse(new InputSource(new StringReader(pXml)));
}
catch (IOException e){
e.printStackTrace();
}
catch (SAXException e)
{
e.printStackTrace();
}
--------------------------------------------------------------------------
Then I receive the following Message:
It seems that the stack can not be controlled.
Please give me an idea of what happens here and how to do it in the
right way!!
--------------------------------------------------------------------------
