Hi,
If you were using Tomcat setup, I would recommend to update a newer version of Tomcat that supports java8. As I understand this is a servlet container issue, so we need to upgrade embedded jetty version to a version that supports java8. In mean time, you can use/test/try multi-process installation : http://www.molgun.com/deploying-apache-manifoldcf-to-apache-tomcat-on-ubuntu-server.html http://manifoldcf.apache.org/release/trunk/en_US/how-to-build-and-deploy.html#Command-driven+multi-process+model On Sunday, May 18, 2014 2:59 PM, Arcadius Ahouansou <[email protected]> wrote: Hi Karl and Ahmet . I just tried this on windows8 64bit and I am seeing the same issue when I try to access the page http://localhost:8345/mcf-crawler-ui/documentstatus.jsp The stack-trace is the same as on Linux (see below) @Karl: Maybe, your Manifold startup picked up JDK6-7? @Ahmet: I am using the standard download http://www.apache.org/dyn/closer.cgi/manifoldcf/apache-manifoldcf-1.6-bin.zip The Jetty version 7.4 in ManifoldCF relies on the Tomcat Jasper JSP compiler and the Eclipse ecj.jar Java compiler. Apparently, ecj.jar is not compatible with the JDK8 There are many discussions about this know issue at : - https://bugzilla.redhat.com/show_bug.cgi?id=1080026 - https://github.com/processing/processing/issues/2260 and also - https://support.lucidworks.com/hc/en-us/articles/201784186-Error-in-Javac-compilation-for-JSP-in-LucidWorks-Search-UI My System: C:\>echo %JAVA_HOME% c:\Program Files\Java\jdk1.8.0 C:\> C:\>java -version java version "1.8.0" Java(TM) SE Runtime Environment (build 1.8.0-b132) Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode) C:\> Stacktrace: Caused by: org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 1 in the generated java file The type java.util.Map$Entry cannot be resolved.
