		return !((String)value).equalsIgnoreCase("false");
	    else
		return ((String)value).equalsIgnoreCase("true");
	}
	if (value instanceof Boolean)
	    return ((Boolean)value).booleanValue();
	return def;
public static booleangetBooleanProperty(java.util.Properties props, java.lang.String name, boolean def)
Get a boolean valued property.

	return getBoolean(props.get(name), def);
public static booleangetBooleanSessionProperty(javax.mail.Session session, java.lang.String name, boolean def)
Get a boolean valued property.

	return getBoolean(session.getProperties().get(name), def);
public static booleangetBooleanSystemProperty(java.lang.String name, boolean def)
Get a boolean valued System property.

	try {
	    return getBoolean(System.getProperties().get(name), def);
	} catch (SecurityException sex) {

	/*
	 * If we can't get the entire System Properties object because

	    try {
		return Integer.parseInt((String)value);
	    } catch (NumberFormatException nfex) { }
	}
	if (value instanceof Integer)
	    return ((Integer)value).intValue();
	return def;
public static intgetIntProperty(java.util.Properties props, java.lang.String name, int def)
