Exception starting filter [DCCSoloSessionManagerFilter] when starting dscc7 to tomcat 10.0.22

User_2AXQ6

Hello,

I have installed Directory Server on my Windows 2019 servers without issues following the stops from the oracle documentation. I am now trying to deploy the dscc7.war file to a tomcat web server using the UI. the file is deployed successfully, but the dscc7 app does not start. and In the log, I see the error below. I guess it is a configuration issue but I have re-installed twice and hit the same problem. Can you help please?

I can see this class DCCSoloSessionManagerFilter class is in the classes' folder under the WEB-INF folder so not sure why Tomcat is not seeing it. it is located here:

E:\Tomcat10.0\webapps\dscc7\WEB-INF\classes\com\sun\web\admin\directory\dcc\solo

here is the entry in my web.xml. what is the issue ?

<filter>

 <filter-name>DCCSoloSessionManagerFilter</filter-name>

 <filter-class>com.sun.web.admin.directory.dcc.solo.DCCSoloSessionManagerFilter</filter-class>

 <init-param>

   <param-name>ignore-path</param-name>

   <param-value>/images/*</param-value>

 </init-param>

</filter>

<filter-mapping>

 <filter-name>DCCSoloSessionManagerFilter</filter-name>

 <url-pattern>/*</url-pattern>

</filter-mapping>
