我面临相关问题。我已经在 Weblogic 上安装了 WebCenter Sites。我的环境是
RHL 5 甲骨文 11gr1
在我们的托管服务器上部署“cs”期间，出现 log4j 错误。我必须编辑 weblogic.xml 并添加以下内容
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
部署“cas”时发生相同的 log4j 错误，必须将上述内容添加到 cas weblogic.xml
然后是找不到 cas.properties 文件的错误。
该文件位于 /home/oracle/oracle/webcenter/sites/bin 以及其他三个文件
host.properties jbossTicketCacheReplicationConfig.xml 和 libsigar-amd64-linux.so
一旦我将它们复制到 /cas/WEB-INF/classes 中，我就能够毫无错误地部署 cas，并且 Webcenter Sites 安装成功。
我可以成功访问登录页面
[http://192.168.14.125:16400/cas/login?service=http%3A%2F%2F192.168.14.125%3A16400%2Fcs%2Fwem%2Ffatwire%2Fwem%2FWelcome]
一旦我尝试使用 fwadmin 登录，它就会进入重定向循环。

我用这篇文章中提到的条目编辑了 setDomainEvn.sh
if [ "${PRE_CLASSPATH}" != "" ] ; then
PRE_CLASSPATH="/export/home/bea/domains/cas/WEB-INF/lib/commons-lang-2.4.jar;/export/home/bea/domains/cas/WEB-INF/lib/quartz-1.5.2.jar;/export/home/bea/domains/cas/WEB-INF/lib/jstl-api-1.2.jar;/home/oracle/oracle/webcenter/sites/MSXML.jar${COMMON_COMPONENTS_HOME}/modules/oracle.jdbc_11.1.1/ojdbc6dms.jar${CLASSPATHSEP}${PRE_CLASSPATH}"
export PRE_CLASSPATH
else
PRE_CLASSPATH="/export/home/bea/domains/cas/WEB-INF/lib/commons-lang-2.4.jar;/export/home/bea/domains/cas/WEB-INF/lib/quartz-1.5.2.jar;/export/home/bea/domains/cas/WEB-INF/lib/jstl-api-1.2.jar;/home/oracle/oracle/webcenter/sites/MSXML.jar${COMMON_COMPONENTS_HOME}/modules/oracle.jdbc_11.1.1/ojdbc6dms.jar"
export PRE_CLASSPATH
fi
即使在那之后我也遇到了同样的错误。
观察者很有趣，我已经安装了带有 oracle 数据库选项的 Webcenter 站点，但是在我的 cas.properties 文件中，我有以下条目
#database.hibernate.dialect=org.hibernate.dialect.OracleDialect
#database.hibernate.dialect=org.hibernate.dialect.MySQLDialect
database.hibernate.dialect=org.hibernate.dialect.HSQLDialect
任何想法这里发生了什么？
