error 404 : dspace backend update 7.4 to 7.6

[Jorge Alberto Bonilla Castaneda]

hello everyone

I followed the documentation in this process but when I finished I received an HTTP 404 message when entering /server

I was reading similar cases saying that it could be some kind of problem with permissions, but that doesn't convince me because with version 7.4 everything worked normally.

somebody could help me ?

Check your Tomcat logs.  If Tomcat can't load the server webapp cleanly then /server will return a 404.  Happened to me earlier in the week.

It could be something else, but I usually start with Tomcat.  There's also a page on the DSpace wiki with some troubleshooting tips: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error

Well, reviewing the log I have these errors :

Any idea how to solve them?

[DSpace Technical Support]

The key error here is this one:

 Caused by: java.lang.ClassNotFoundException: org.dspace.app.bulkaccesscontrol.model.BulkAccessConditionConfiguration

That appears to be saying that Tomcat cannot find your "dspace-api.jar" file?  That class should be in the JAR which begins with "dspace-api", so if it's "NotFound", then that implies that Tomcat cannot see this JAR.  Maybe your build or deploy didn't work properly for the backend?   Or maybe your Tomcat "server.xml" isn't loading the correct "server" webapp directory?

It's difficult to say for certain, but it definitely sounds like your backend is not installed correctly (or misconfigured in some way).
