Unfortunately, Tomcat is not enough for LiveCycle ES 8.0
Tomcat is only a Web Container, meaning it can provide services only to JSPs and servlets. LiveCycle also has EJBs which need the services of an EJB Container. Therefore, you need a full-fledged J2EE application server such as JBoss 4.0.3SP1, IBM WebSphere AS 126.96.36.199 or Bea WebLogic AS 9.2
Please note, JBoss actually has Tomcat 5.5 as its Web Container implementation.
We have installed LiveCycle Reader Extensions using the turnkey installation with JBoss. I dont't know how to process the watch folder mechanism in Reader Extensions. Could you please help me how to use the built-in Watched Folder mechanism and also could you please provide any other Documentation available for this mechanism
