在WAS 8.5.5.10中从我的应用程序连接Db2数据库时，我面临以下异常。我的应用程序是用1.8构建的，我在web.xml中提到了db2配置细节。指导我解决这个问题。
org.springframework.jndi.JndiLookupFailureException: JndiObjectTargetSource failed to obtain new target object; nested exception is com.ibm.websphere.naming.CannotInstantiateObjectException: Exception occurred while the JNDI NamingManager was processing a javax.naming.Reference object. [Root exception is javax.xml.stream.FactoryConfigurationError: Provider javax.xml.stream.XMLInputFactory could not be instantiated: java.util.ServiceConfigurationError: javax.xml.stream.XMLInputFactory: Provider com.ctc.wstx.stax.WstxInputFactory not a subtype]

Web.xml中
<resource-ref id="FrontEnd_DataSource">
<description>DB2 database</description>
<res-ref-name>db2_DB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
有人对此有所了解吗？
[根异常是javax.xml.stream.FactoryConfigurationError：无法实例化提供程序javax.xml.stream.XMLInputFactory：java.util.ServiceConfigurationError：javax.xml.stream.XMLInputFactory：Provider com.ctc。 wstx.stax.WstxInputFactory不是子类型]
