解决办法

在WEB-INF文件夹下，加上weblogic.xml，让WebLogic 10先引用WEB-INF下面的jar，内容如下：


<?           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           =           "http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsdhttp://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd"           >          


                      <           weblogic-version           >10.3.1</           weblogic-version           >

                      <           container-descriptor           >

                      </           container-descriptor           >          


           </           weblogic-web-app           >

这里解释了xml-api.jar的问题 
http://stackoverflow.com/questions/4925901/classcastexception-while-parsing-xml-with-weblogic

这篇文档再次印证了那两个问题

解决办法

删掉war包中的xml-apis就可以了

问题原因说明

因为我们刚在weblogic.xml里设置了优先加载WEB-INF中的jar，那么要删掉冲突的jar。
http://www.liferay.com/community/wiki/-/wiki/Main/Weblogic+tips 里说的很清楚：

 



The weblogic.xml Web application deployment descriptor contains a <prefer-web-inf-classes> element (a sub-element of the<Container-descriptor> element). By default, this element is set to false. **Setting this element to true subverts the classloader delegation model so that class definitions from the Web application are loaded in preference to class definitions in higher-level classloaders.** This allows a Web application to use its own version of a third-party class, which might also be part ofWebLogic Server. 
**When this setting is enabled in weblogic.xml, the following jars has to be removed from portal WEB-INF/lib** (jars with javax.xmlpackage): 
jaxrpc.jar
stax.jar
wstx.jar
xml-apis.jar



问题3(java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval())


org.springframework.beans.factory.BeanCreationException: Error creating bean with name            'sessionFactory'            defined in ServletContext resource [/WEB-INF/dorado-home/app-context.xml]: Invocation of init method failed; nested exception is **java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z**

           Factory.doCreateBean(AbstractAutowireCapableBeanFactory.java:           519           )



解决办法

把war中的hibernate-jpa-2.0-api-1.0.0.Final.jar删掉。

问题原因说明

war和Weblogic 10本身都有jpa的jar包，冲突。

问题4(**java.lang.NoClassDefFoundError: javax/persistence/Cacheable**)


org.springframework.beans.factory.BeanCreationException: Error creating bean with name            'sessionFactory'            defined in ServletContext resource [/WEB-INF/dorado-home/app-context.xml]: Invocation of init method failed; nested exception is **java.lang.NoClassDefFoundError: javax/persistence/Cacheable**

                      at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:           519           )




解决办法

将hibernate-jpa-2.0-api-1.0.0.Final.jar放到%WEBLOGIC_HOME%\jdk160_11\jre\lib\ext中，让它在Weblogic 10的JPA jar之前引用。

如果使用的是jrockit，则应该将这个jar放在%WEBLOGIC_HOME%\jrockit_160_05\jre\lib\ext中

问题原因说明

Weblogic 10.3里的jpa是1.0的（%WEBLOGIC_HOME%\modules\javax.persistence_1.0.0.0_1-0-2.jar），而我们使用的是2.0版本的。而JPA 1.0好像不支持缓存，所以，单纯的删除hibernate-jpa-2.0-api-1.0.0.Final.jar是不行的。

解决办法

把velocity-tools-2.0.jar删掉

问题6(Bad date header)


java.lang.IllegalArgumentException: Bad date header:            'Mon, 04 Jul 2011 06:33:24 GMT'                   at weblogic.servlet.internal.ServletRequestImpl.getDateHeader(ServletRequestImpl.java:           983           )



解决办法

安装WebLogic 10gR3版本的CR380042_103GA.jar补丁，具体办法：



首先将CR380042_103GA.jar（ 点击下载）拷贝到WebLogic的domain的lib目录下；



然后修改setDomainEnv.sh/setDomainEnv.bat（前者对应linux系统，后者为windows系统），在最后设置的CLASSPATH中增加，如下： 

CLASSPATH=.../mydomain/lib/CR380042_103GA.jar;${CLASSPATH}

 

问题7(javassist.util.proxy.ProxyFactory.setUseCache(Z))

            at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:            644            )




xwork-core-2.1.6.jar导致的

参考ISSUE: http://www.bsdn.org/projects/dorado7/issue/dorado7-1157

问题8：(weblogic.application.ModuleException)


weblogic.application.ModuleException:           


            com.ctc.wstx.stax.WstxInputFactory cannot be cast to javax.xml.stream.XMLInputFactory



 

这是因为包冲突了，如果项目的lib里有wstx-asl-xxx.jar，部署之前先从war包里删除这些jar包，再部署就可以了。
注意还要在WEB-INF目录下添加一个weblogic.xml，设置属性优先使用当前应用的包文件。配置内容参考问题1

 问题9：No bean named 'dorado.packagesConfigLoader' is defined

解决办法就是在WEB-INF目录下添加weblogic.xml文件，配置内容参考问题1
