取arraylist的HashMap裡面的值

Map map = new HashMap();
Iterator iter = map.entrySet().iterator();
while (iter.hasNext()) {
    Map.Entry entry = (Map.Entry) iter.next();
    Object key = entry.getKey();
    Object val = entry.getValue();
}

web service 的bug

org.springframework.beans.factory.BeanDefinitionStoreException: Parser configuration exception parsing XML from ServletContext resource [/WEB-INF/servlet-context.xml]; nested exception is javax.xml.parsers.ParserConfigurationException: Unable to validate using XSD: Your JAXP provider [gnu.xml.dom.JAXPFactory@4cf1e2d9] does not support XML Schema. Are you running on Java 1.4 with Apache Crimson? Upgrade to Apache Xerces (or Java 1.5) for full XSD support.

我以為是spring的問題，實際上刪除gnujaxp.jar檔就可
