Hello Mohamed, It looks like your error message was cut off / incomplete. I don't see any mention of DSpaceLocaleAction class in the error stack that you posted (and it looks to me like it might be missing key information).
However, based on what you included, my guess would be that you might have older configurations (something in the [dspace]/config/ directory) that are conflicting with newer ones. You might want to try temporarily moving the [dspace]/config directory to a backup location (e.g. [dspace]/config.backup) and then re-running "ant update" (from the DSpace 6.2 [src]/dspace/target/dspace-installer/ folder). This will reinstall all the default 6.x configurations into [dspace]/config/ You could then try seeing if the application runs -- and if so, re-modify your configurations as needed. If this doesn't work, I'd suggest checking your dspace.log files more closely to see if any other errors are occurring *prior* to the one you posted. It's possible there's other prior errors that resulted in this later one. Let us know on the list if you need further help, Tim On Fri, Apr 6, 2018 at 5:23 PM Mohamed Mohideen Abdul Rasheed < mohid...@umd.edu> wrote: > After upgrade to DSpace 6.2 from DSpace 5.7, the following stacktrace is > logged and the application fails to start: > > 2018-04-06 21:39:07,045 ERROR > org.dspace.app.xmlui.cocoon.DSpaceCocoonServletFilter @ Serious Error > Occurred Processing Request! > javax.servlet.ServletException: org.apache.cocoon.ProcessingException: > Sitemap: error invoking action > at <map:act type="locale"> - jndi:/localhost/sitemap.xmap:794:64 > at > org.apache.cocoon.servlet.RequestProcessor.service(RequestProcessor.java:230) > ... > at java.lang.Thread.run(Thread.java:745) > Caused by: org.apache.cocoon.ProcessingException: Sitemap: error invoking > action > at <map:act type="locale"> - jndi:/localhost/sitemap.xmap:794:64 > at > org.apache.cocoon.ProcessingException.throwLocated(ProcessingException.java:111) > ... > ... 52 more > Caused by: org.dspace.core.PluginInstantiationException: Cannot load > plugin class: java.lang.ClassNotFoundException: > at > org.dspace.core.LegacyPluginServiceImpl.getAnonymousPlugin(LegacyPluginServiceImpl.java:211) > at > org.dspace.core.LegacyPluginServiceImpl.getPluginSequence(LegacyPluginServiceImpl.java:194) > ... > ... 65 more > Caused by: java.lang.ClassNotFoundException: > at java.lang.Class.forName0(Native Method) > at java.lang.Class.forName(Class.java:274) > at > org.dspace.core.LegacyPluginServiceImpl.getAnonymousPlugin(LegacyPluginServiceImpl.java:206) > ... 73 more > > We have not made any changes to the DSpaceLocaleAction class and our > dspace.cfg have locale configured as > default.locale = en > > > I will appreciate any pointers on what could be causing this problem. > > -- > 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 dspace-tech+unsubscr...@googlegroups.com. > To post to this group, send email to email@example.com. > 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.
