[java] problema con config.xml

[nicolad1988]

salve vorrei salvare le impostazioni del mio programma in un file interno al jar.
file config.xml

 <!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
 <?xml version="1.0" encoding="UTF-8"?>

    <!-- DTD for properties -->

    <!ELEMENT properties ( comment?, entry* ) >

    <!ATTLIST properties version CDATA #FIXED "1.0">

    <!ELEMENT comment (#PCDATA) >

    <!ELEMENT entry (#PCDATA) >

    <!ATTLIST entry key CDATA #REQUIRED>

main

 Properties properties = new Properties();
		InputStream fis = getClass().getResourceAsStream ("/config.xml");
		 try {
			properties.loadFromXML(fis);
		} catch (InvalidPropertiesFormatException e1) {
			e1.printStackTrace();
		} catch (IOException e1) {
			e1.printStackTrace();
		}

errore:

help nessuno sà rispondermi

il tuo config.xml non e un xml ma un dtd ... cioè la definizione della struttura del xml ... (che tu hai copiato dal sito della sun ) ... il tuo xml deve essere composto da un elemento root "properties" con zero o un tag "comment" e zero o più tag "entry" . il tag entry deve avere definito l'attributo key ...

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<comment>commento</comment>
<entry key="property1">value1</entry>
<entry key="property2">value2</entry>
</properties>

Leggiti questo tutorial sui dtd.

cmq bastava definire 2,3 proprietà e invocare il metodo "inverso" storeToXML
