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"

         334 
         )

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

         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**

         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}

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
