tomcat移植到weblogic下问题小结

1.HQL不能执行。解决方法：在/web-inf下新增weblogic.xml 内容如下：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE weblogic-web-app PUBLIC "-//BEA Systems, Inc.//DTD Web Application 10.0//EN" "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd"><weblogic-web-app> <container-descriptor>  <prefer-web-inf-classes>true</prefer-web-inf-classes> </container-descriptor></weblogic-web-app>

2.在weblogic下启动时报错；解决方法：删除lib下一个包 名为：xml-apis.jar

3.dwr报session error

解决方法：在web.xml中配置DWR的Servlet的时候添加以下配置

              <servlet>

              <servlet-name>dwr-invoker</servlet-name>

              <servlet-class>

                     org.directwebremoting.servlet.DwrServlet

              </servlet-class>

              <!-- 解决dwr报session error 错误 -->

       <init-param>

           <param-name>crossDomainSessionSecurity</param-name>

           <param-value>false</param-value>

       </init-param>

       <!--end  解决dwr报session error 错误 -->

              <init-param>

                     <param-name>debug</param-name>

                     <param-value>true</param-value>

              </init-param>

              <init-param>

                     <param-name>activeReverseAjaxEnabled</param-name>

                     <param-value>true</param-value>

              </init-param>

              <init-param>

                     <param-name>

                            initApplicationScopeCreatorsAtStartup

                     </param-name>

                     <param-value>true</param-value>

              </init-param>

              <init-param>

                     <param-name>maxWaitAfterWrite</param-name>

                     <param-value>500</param-value>

              </init-param>

              <load-on-startup>1</load-on-startup>

       </servlet>

 

4 .打印问题

1). 修改了打印工具框架

2). 在每个实现了DataSource的类中的getManager()方法中用

InpuStrean is = request.getSession().getServletContenxt().getResourceAsStream(filePath);//其中filePath是.jasper的存放路径以“/”开头。

Return new ReportManager(is,….);

5.页面问题：在weblogic下的项目，页面上用El表达式：${表达式?值1:值2}

若值2为变量时，则“：”后面必须加上一个空格，或者用小括号将值2括起来，不然页面会报错。
