ERROR [org.springframework.web.context.ContextLoader] - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Parser configuration exception parsing XML from ServletContext resource [/WEB-INF/conf/applicationContext-dataSource.xml]; nested exception is javax.xml.parsers.ParserConfigurationException: Unable to validate using XSD: Your JAXP provider [gnu.xml.dom.JAXPFactory@5e7663] does not support XML Schema.

解決方法：

按錯(cuò)誤提示中說(shuō)的“Are you running on Java 1.4 or below with Apache Crimson? Upgrade to Apache Xerces (or Java 1.5) for full XSD support”，我的jdk版本過(guò)低？！我安裝的可是1.5，在dos窗口中java -version一查看，還真是1.4，這才明白過(guò)來(lái)，是我剛剛裝的Oracle搞得鬼。于是，將環(huán)境變量中oracle的jre刪除掉。
重試，還錯(cuò)？而且還是報(bào)一模一樣的錯(cuò)誤。暈死>_Unable to validate using XSD: Your JAXP provider [gnu.xml.dom.JAXPFactory@5e7663] does not support XML Schema.”把這個(gè)錯(cuò)誤貼到google上，果然解決方法一大堆，不外乎以下幾種：
1，Xerces版本可能過(guò)低，導(dǎo)致解析spring的配置文件時(shí)候報(bào)錯(cuò)，靠這句話本身就有問(wèn)題，spring要解析自己的xml文檔，干嘛拿一個(gè)不能解析的解析工具??？腦子秀逗了。不過(guò)，話雖如此，我還是檔了一對(duì)不同版本的Xerces的jar報(bào)一個(gè)一個(gè)試，失敗！
2，Xerces與j2ee里的xmls.api有沖突，那到底應(yīng)該刪除掉哪個(gè)呢？不管了，試吧，先把Xerces刪除掉，重啟tomcat，失??！跑到myeclipse里將其xmls.api包刪除，失敗！真累啊
3，我實(shí)在找不到第三個(gè)錯(cuò)誤的可能性了，怎么辦，算了，豁出去了，一個(gè)一個(gè)單詞看錯(cuò)誤信息吧，我看啊看啊，終于：一個(gè)下午過(guò)去了，繼續(xù)看啊看啊Your JAXP provider [gnu.xml.dom.JAXPFactory@5e7663] does not support XML Schema.    [b]gnu,[/b]好像在那兒見(jiàn)過(guò)啊，快點(diǎn)想起來(lái)，對(duì)了，jfreechart里好像有這個(gè)東東，一看果然gunjaxp.jar，jfreechart里有這個(gè)東東，刪掉它試試，成功了
