Expecting suggestions to resolve this.

Hi Eugene,

It sounds like you may be trying to build DSpace with an unsupported Java version (possibly Java 17?).  At this time, DSpace 7 only supports Java 11 as noted in the installation instructions at https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-JavaJDK11(OpenJDKorOracleJDK)

If you run into other issues, let us know on this list.

Dear Tim,

I have resolved that issue and completed the installation - both backend and front end. I have installed apache2 and set up the reverse proxy as well with https.

URL of this instance is - https://rer.jfn.ac.lk/

But, I am getting an error message when trying the login.html - "Failed to connect with backend"

Part of the /dspace-source/dspace/config/local.cfg is given below:

dspace.dir=/opt/dspace

dspace.server.url = http://localhost:8080/

dspace.ui.url = http://localhost:4000

Kindly help me to resolve this issue.

Thanks

Hi Eugene,

Please see our "Common Installation" issues guide, especially the sections on how to find the underlying error message: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-Troubleshootanerrororfinddetailederrormessages

I suspect the underlying error might be this "No _links section found at...", but you should check to be sure. If that's the error though, here's the guide for fixing it: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22No_linkssectionfoundat...%22errorfromUserInterface

Several other guides are listed in that same section for other common error messages, so it's important to find the detailed​ error message, as this will guide you to which fix should work for you.

Good luck and let us know on this list if you need more help.

Tim
