从websphere6.1迁移到weblogic10.3的问题总结--转
http://blog.itpub.net/9399028/viewspace-692974/
以前用weblogic低版本的時候，感覺挺容易的，也沒什么要注意的，這次真正把應用從websphere遷移到weblogic下后，發現問題還是真多了。系統采用war包的方式部署。

原因：
在weblogic上部署war包的話，默認是不展開的，所以如下的hibernate配置不能解析。
<bean id="sessionFactory"
?????????????????? class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">???????????
?????????????????? <property name="mappingDirectoryLocations">
??????????????????????????? <list>
???????????????????????????????????? <value>classpath:/com/edu/nts/entity</value>
??????????????????????????? </list>
?????????????????? </property>
</bean>
解決辦法：
針對weblogic的部署方式，必須改為如下方式。
<bean id="sessionFactory"
?????????????????? class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">???????????
?????????????????? <property name="mappingResources">
??????????????????????????? <list>
???????????????????????????????????? <value>com/edu/nts/entity/AidStudentInfo.hbm.xml</value>??????????????
???????????????????????????????????? <value>com/edu/nts/entity/AidStudentList.hbm.xml</value>
???????????????????????????????????? <value>com/edu/nts/entity/AidStudentListTemp.hbm.xml</value>
???????????????????????????????????? 。。。
??????????????????????????? </list>
</bean>
雖然沒法偷懶用上面的注入方式，但還是可以通過編寫一個小程序生成上面的明細注入片段，修改量不會太大。

原因：
在web.xml中log4j的配置方式問題，默認情況log4j.properties放在classes目錄下，而由于war沒展開，找不到這個文件，所以把它直接放WEB-INF目錄下，并去掉原來web.xml里面的如下配置：
???????? <servlet>
?????????????????? <servlet-name>log4j</servlet-name>
?????????????????? <servlet-class>
??????????????????????????? org.springframework.web.util.Log4jConfigServlet
?????????????????? </servlet-class>
?????????????????? <load-on-startup>1</load-on-startup>
???????? </servlet>
解決辦法：
新建一個servlet，初始化log4j配置文件：
public void init() throws ServletException {
?
?????????????????? InputStream is = getServletContext().getResourceAsStream(
???????????????????????????????????? "/WEB-INF/log4j.properties");
?????????????????? Properties props = new Properties();
?????????????????? try {
??????????????????????????? props.load(is);
?????????????????? } catch (IOException e) {
??????????????????????????? System.err.println("Load log4j configuration failed");
?????????????????? }
?????????????????? PropertyConfigurator.configure(props);
?
???????? }
?
并注冊到web.xml文件中：
<servlet>
??? <servlet-name>Log4jInitServlet</servlet-name>
??? <servlet-class>com.edu.nts.web.servlet.Log4jInitServlet</servlet-class>
??? <load-on-startup>0</load-on-startup>
? </servlet>
?
問題三：
由于種種原因，該應用程序必須部署到服務器的根目錄（/）下面，否則樣式及功能都會出現問題。
解決辦法：
為了把應用程序的context root改到根目錄，創建了一個weblogic.xml文件，放到war包的WEB-INF目錄下，內容如：
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">
??? <weblogic-version>10.3.2</weblogic-version>
??? <context-root>/</context-root>
</weblogic-web-app>
?
問題四：
打開登錄頁面報錯，后臺錯誤如下：
####<2011-4-2 下午06時00分11秒 CST> <Info> <ServletContext-> <javasvr> <AdminServer> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <> <1301738411265> <BEA-000000> <redirect.jsp:1:1: The validator class: "org.apache.taglibs.standard.tlv.JstlCoreTLV" has failed with the following exception: "java.lang.ClassCastException: weblogic.xml.jaxp.RegistrySAXParserFactory cannot be cast to javax.xml.parsers.SAXParserFactory".

<%@ page language="java" pageEncoding="UTF-8"%>
^---------------------------------------------^
>?
原因：jar包沖突，以及jar包加載順序的問題引起
解決辦法：
刪除lib目錄下的xml-apis.jar，并在上面的weblogic.xml中增加如下：
???????? <container-descriptor>
?????????????????? <prefer-web-inf-classes>true</prefer-web-inf-classes>
???????? </container-descriptor>
使classloader首先加載web－info下的jar文件，修改后的weblogic.xml如下：
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="

??? <context-root>/</context-root>
???????? <container-descriptor>
?????????????????? <prefer-web-inf-classes>true</prefer-web-inf-classes>
???????? </container-descriptor>
</weblogic-web-app>

>?
原因：
配置的weblogic連接池名稱命民規則問題。
解決辦法：
由于數據源的jndi為：jdbc/orcl，數據源的名稱必須為jdbc.orcl，否則就會報上面的類似錯誤。
?
問題六：
錯誤信息忘記了，頁面訪問報編譯錯誤。
原因：
類似如下的jstl判斷語法不能正確解析，真是奇怪
${changeForm.change.oldVal == 1 ? 男 : changeForm.change.oldVal ==0?女:’’}
解決辦法：
采用choose語法修改為如下
<c:choose>
???????? <c:when test="${ changeForm.change.oldVal ==1}">男</c:when>
???????? <c:when test="${ changeForm.change.oldVal ==0}">女</c:when>
???????? <c:otherwise></c:otherwise>
</c:choose>
?
問題七：
getServletContext().getRealPath("/upload");返回為null的問題。
原因：
由于weblogic下，war沒有展開，所以也就不存在相對于應用程序的路徑realpath。
解決辦法：
若是為了得到相對路徑，采用以下方式
getServletContext().getResource("/upload").getPath();
若是為了加載資源文件，則采用如下方式
InputStream is = getServletContext().getResourceAsStream(
???????????????????????????????????? "/WEB-INF/log4j.properties");
Properties props = new Properties();
try {
???????? props.load(is);
} catch (IOException e) {
???????? System.err.println("Load log4j configuration failed");
}
PropertyConfigurator.configure(props);
?
問題八：
采用jquery的方式異步請求后臺數據，后臺采用PrintWriter返回結果，結果頁面不能正確加載數據。
原因：
PrintWriter writer = (PrintWriter) response.getWriter();
writer.write("failure");
writer.close();
以上close之前，少了一句
PrintWriter writer = (PrintWriter) response.getWriter();
writer.write("failure");
writer.flush();
writer.close();
