Hi, This error seems to be a Tomcat specific error, and may not have to do with DSpace itself (I don't see anything DSpace specific in those logs you sent along). So, you may want to look more closely at the Tomcat error logs and see if it's reporting additional errors there.
Based on the information you've provided, we don't have enough information to help you resolve this issue. Please, take a look at our guide on Troubleshooting Errors, which provides useful information about where to find error messages, where to search for answers, and what to send along to mailing lists for help: https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error - Tim On Thu, Sep 28, 2017 at 7:46 AM Ηλιας Χρηστου <[email protected]> wrote: > org.apache.catalina.startup.Catalina start > SEVERE: The required Server component failed to start so Tomcat is unable > to start. > and > org.apache.catalina.startup.Catalina start > SEVERE: The required Server component failed to start so Tomcat is unable > to start. > org.apache.catalina.LifecycleException: Failed to start component > [StandardServer[8005]] > at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:153) > at org.apache.catalina.startup.Catalina.start(Catalina.java:693) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:294) > at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:428) > Caused by: org.apache.catalina.LifecycleException: Failed to start > component [StandardService[Catalina]] > at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:153) > at > org.apache.catalina.core.StandardServer.startInternal(StandardServer.java:738) > at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:147) > ... 7 more > Caused by: org.apache.catalina.LifecycleException: Failed to start > component [StandardEngine[Catalina]] > at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:153) > at > org.apache.catalina.core.StandardService.startInternal(StandardService.java:444) > at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:147) > ... 9 more > Caused by: org.apache.catalina.LifecycleException: A child container > failed during start > at > org.apache.catalina.core.ContainerBase.startInternal(ContainerBase.java:1129) > at > org.apache.catalina.core.StandardEngine.startInternal(StandardEngine.java:300) > at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:147) > ... 11 more > how to solve these problems? > > -- > You received this message because you are subscribed to the Google Groups > "DSpace Technical Support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at https://groups.google.com/group/dspace-tech. > For more options, visit https://groups.google.com/d/optout. > -- Tim Donohue Technical Lead for DSpace & DSpaceDirect DuraSpace.org | DSpace.org | DSpaceDirect.org -- You received this message because you are subscribed to the Google Groups "DSpace Technical Support" group.
